difficult的名词形式是difficulty，复数形式是difficulties。difficult的基本意思是“难的”,指难以做到的、难以解决的、难以理解的、难以承受的事物,多用于智力或情感方面,侧重需付出大量思考或运用技巧方能解决。difficult的用法：1、difficult可用作定语、表语或宾语补足语。例：English is a difficult language to learn.译文：英语是一门难学的语言。2、作表语时,后面可接介词of或to引起的短语,也可接动词不定式,句子的主语是动词不定式的逻辑宾语。例：We had hoped that we would be able to leave tomorrow, but it"s beginning to look difficult.译文：我们原希望明天可以出发,但是这事开始显得困难起来。3、用作宾语补足语例：I found English difficult at first.译文：起初我发觉英语难学。扩展资料：difficult是形容词，没有无可数和不可数的说法，difficult的名词difficulty，才有可数和不可数的说法。difficulty后常接“of+ n. / v -ing”或“in+ v -ing”作定语, in有时可省去,不用动词不定式。difficulty作“困难,麻烦”解时,指必须付出大量的思考和运用技巧才能解决的任何困难,当表示抽象的困难时,是不可数名词,既不能与不定冠词连用,也不能用于复数形式。表示具体的难处、难事、麻烦时,是可数名词,既可与不定冠词连用,也可用于复数形式。difficulty引申还可作“困境(尤指经济上的拮据)”解,这时常用复数形式。参考资料来源：百度百科-difficult

Rotary drilling reverse circulation ( either using drilling mud and / or compressed air or gas) can be a useful alternative to direct circulation methods. The reverse circulation technique is particularly useful for drilling relatively shallowlarge diameter boreholes. In a typical reverse circulation operation utilizing drilling mud，the drilling mud ( or treated water) flows from the slush pump ( or mud pump) to the top of the annulus between the outside of the drill string and the inside the borehole，down the annulus space to the bottom of the borehole. At the bottom of the borehole the drilling mud entrains the rock bit cuttings and flows through the large orifice in the drill bit and then upward to the surface through the inside of the drill string. At the surface the cuttings are removed from the drilling mud by the shale shaker and the drilling mud is returned to the mud tanks.Figure 14. 5 Dual tube ( or dual drill pipe) closed reverse circulation operationReverse circulation can also be carried out using air and gas drilling techniques. Figure 14. 5 shows a typical application of reverse circulation using compressed air as the drilling fluid ( or mist，unstable foam) . This example is a dual tube ( or dual drill pipe ) closed reverse circulation system. The closed system is characterized by an annulus space bounded by the inside of the outer tube and the outside of the innertube. This is a specialized type of reverse circulation and is usually limited to small single and double drilling rigs with top head rotary drives. Dual tube and dual drill pipe are available from a number of manufacturers in the United States and elsewhere in world.Reverse circulation drilling operations require specially fabricated drill bits. Figure 14. 6 shows a schematic of the interior flowchannel of a tricone rotary drill bit designed for reverse circulation. These drill bits utilize typical roller cutter cones exactly like those used in direct circulation drill bits. These bits，however，have a large central channel opening that allows the circulation fluid flowwith entrained rock cuttings to flowfrom the bottom of the borehole to the inside of the drill string and then to the surface.Most tri-cone drill bits with a diameter of 5 3/4 in or less are designed with the central flowchannel as shown in above figure. These direct circulation drill bits usually have three orifices that can be fitted with nozzles. Tri-cone roller cutter drill bits for reverse circulation operations are available in diameters from 4 2/3 to 31 in. The larger diameter bits for reverse circulation operations are usually custom designed and fabricated. Dual wall pipe reverse circulation operations require special skirted drill bits. These skirted drill bits are also custom designed for the particular drilling operation. Most reverse circulation tri-cone bits are manufactured by companies that specialize in geotechnical and mining drilling equipment.Figure 14. 6 Schematic of the internal flowchannel of a tricone rotary drill bit designed for reverse circulation operations

highest occupied molecular orbital最高占有分子轨道; 例句Molecular orbital of the conjugated diene. 共轭二烯基态的分子轨道。

是处理双原子分子及多原子分子结构的一种有效的近似方法，是化学键理论的重要内容。它与价键理论不同，后者着重于用原子轨道的重组杂化成键来理解化学，而前者则注重于分子轨道的认知，即认为分子中的电子围绕整个分子运动。

就是属于SCI哦

一个是存在化学键,是离子化合物.一个是存在分子间力,也就是范德瓦尔兹力,也可称为范德华力.是分子化合物.离子化合物之间有离子键,也就是有电子得失.分子化合物之间的范德华力不存在电子得失.

简单的分子的物质是共价化合物,它本身不能电离出离子,所以不能导电.

请仔细查看此杂志的投稿说明：Compliance with Ethical StandardsTo ensure objectivity and transparency in research and to ensure that accepted principles of ethical and professional conduct have been followed, authors should include information regarding sources of funding, potential conflicts of interest (financial or non-financial), informed consent if the research involved human participants, and a statement on welfare of animals if the research involved animals.Authors should include the following statements (if applicable) in a separate section entitled “Compliance with Ethical Standards” before the References when submitting a paper:Disclosure of potential conflicts of interestResearch involving Human Participants and/or AnimalsInformed consentPlease note that standards could vary slightly per journal dependent on their peer review policies (i.e. double blind peer review) as well as per journal subject discipline. Before submitting your article check the Instructions for Authors carefully.The corresponding author should be prepared to collect documentation of compliance with ethical standards and send if requested during peer review or after publication.The Editors reserve the right to reject manuscripts that do not comply with the above-mentioned guidelines. The author will be held responsible for false statements or failure to fulfill the above-mentioned guidelines.Disclosure of potential conflicts of interestAuthors must disclose all relationships or interests that could have direct or potential influence or impart bias on the work. Although an author may not feel there is any conflict, disclosure of relationships and interests provides a more complete and transparent process, leading to an accurate and objective assessment of the work. Awareness of a real or perceived conflicts of interest is a perspective to which the readers are entitled. This is not meant to imply that a financial relationship with an organization that sponsored the research or compensation received for consultancy work is inappropriate. Examples of potential conflicts of interests that are directly or indirectly related to the research may include but are not limited to the following:Research grants from funding agencies (please give the research funder and the grant number)Honoraria for speaking at symposiaFinancial support for attending symposiaFinancial support for educational programsEmployment or consultationSupport from a project sponsorPosition on advisory board or board of directors or other type of management relationshipsMultiple affiliationsFinancial relationships, for example equity ownership or investment interestIntellectual property rights (e.g. patents, copyrights and royalties from such rights)Holdings of spouse and/or children that may have financial interest in the workIn addition, interests that go beyond financial interests and compensation (non-financial interests) that may be important to readers should be disclosed. These may include but are not limited to personal relationships or competing interests directly or indirectly tied to this research, or professional interests or personal beliefs that may influence your research.The corresponding author collects the conflict of interest disclosure forms from all authors. In author collaborations where formal agreements for representation allow it, it is sufficient for the corresponding author to sign the disclosure form on behalf of all authors. Examples of forms can be foundhere:The corresponding author will include a summary statement in the text of the manuscript in a separate section before the reference list, that reflects what is recorded in the potential conflict of interest disclosure form(s).See below examples of disclosures:Funding: This study was funded by X (grant number X).Conflict of Interest: Author A has received research grants from Company A. Author B has received a speaker honorarium from Company X and owns stock in Company Y. Author C is a member of committee Z.If no conflict exists, the authors should state:Conflict of Interest: The authors declare that they have no conflict of interest.Research involving human participants and/or animals1) Statement of human rightsWhen reporting studies that involve human participants, authors should include a statement that the studies have been approved by the appropriate institutional and/or national research ethics committee and have been performed in accordance with the ethical standards as laid down in the 1964 Declaration of Helsinki and its later amendments or comparable ethical standards.If doubt exists whether the research was conducted in accordance with the 1964 Helsinki Declaration or comparable standards, the authors must explain the reasons for their approach, and demonstrate that the independent ethics committee or institutional review board explicitly approved the doubtful aspects of the study.The following statements should be included in the text before the References section:Ethical approval: “All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.”For retrospective studies, please add the following sentence:“For this type of study formal consent is not required.”2) Statement on the welfare of animalsThe welfare of animals used for research must be respected. When reporting experiments on animals, authors should indicate whether the international, national, and/or institutional guidelines for the care and use of animals have been followed, and that the studies have been approved by a research ethics committee at the institution or practice at which the studies were conducted (where such a committee exists).For studies with animals, the following statement should be included in the text before the References section:Ethical approval: “All applicable international, national, and/or institutional guidelines for the care and use of animals were followed.”If applicable (where such a committee exists): “All procedures performed in studies involving animals were in accordance with the ethical standards of the institution or practice at which the studies were conducted.”If articles do not contain studies with human participants or animals by any of the authors, please select one of the following statements:“This article does not contain any studies with human participants performed by any of the authors.”“This article does not contain any studies with animals performed by any of the authors.”“This article does not contain any studies with human participants or animals performed by any of the authors.”Informed consentAll individuals have individual rights that are not to be infringed. Individual participants in studies have, for example, the right to decide what happens to the (identifiable) personal data gathered, to what they have said during a study or an interview, as well as to any photograph that was taken. Hence it is important that all participants gave their informed consent in writing prior to inclusion in the study. Identifying details (names, dates of birth, identity numbers and other information) of the participants that were studied should not be published in written descriptions, photographs, and genetic profiles unless the information is essential for scientific purposes and the participant (or parent or guardian if the participant is incapable) gave written informed consent for publication. Complete anonymity is difficult to achieve in some cases, and informed consent should be obtained if there is any doubt. For example, masking the eye region in photographs of participants is inadequate protection of anonymity. If identifying characteristics are altered to protect anonymity, such as in genetic profiles, authors should provide assurance that alterations do not distort scientific meaning.The following statement should be included:Informed consent: “Informed consent was obtained from all individual participants included in the study.”If identifying information about participants is available in the article, the following statement should be included:“Additional informed consent was obtained from all individual participants for whom identifying information is included in this article.”
