Jack is too young to go to school. And what"s more , he is poor in health.I wish I could unsay what I said just now.There is reason to suspect that the death occurred between 6:30 and 7 yesterday evening．Poor old George has broken down in the world since his business failed.If our admiration is true, genuine, and progressive we will in the end come to admire the good and cease to_ admire the bad.I was surprised to hear that Tom had failed his exam.About a hundred and fifty yards away I could just make out (勉强看出) three figures approaching the road in our direction.Death often comes swiftly and without warning in time of war.You are welcome to my dictionary，Whenever you need it，just tell me. Don"t be nervous ! It is only a small test. Surely， all of you will pass it. Professor Janssen has agreed to extend the time limit for our term paper.

( 1) As part of the hydrologic cycle，groundwater is always in motion from regions of natural and artificial replenishment to those of natural and artificial discharge. Bodies of stagnant，usually saline，w ater trapped in various porous geological formations do exist，but as long as they do not participate in the hydrologic cycle，they are of little interest to the groundw ater hydrologists.( 2) The porosity n can be an important controlling influence on hydraulic conductivity K. In sampling programs carried out w ithin deposits of w ell-sorted sand or in fracture rock formations，samples w ith high n generally also have high K. How ever，the relationship does not hold on a regional basis to various possible rock and soil types. Clayey soils，for example， usually have higher porosities than sandy or gravelly soils but low er hydraulic conductivities.( 3) In recent years the term aquitard has been used to describe the less-permeable beds in a stratigraphic sequence. These beds may be permeable enough to transmit w ater in quantities that are significant in the study of regional groundw ater flow ，but their permeability is not sufficient to allow exploitation of groundw ater w ithin them. Most geological strata are classified as either aquifers or aquitards.( 4) Of all the words in the hydrologic vocabulary，there are probably none with more abundant meaning than the term aquifer. It means different things to different people，and perhaps different things to the same person at different times. It is used to refer to individual geologic layers，to complete geologic formations，and even to groups of geologic formations. The term must alw ays be view ed in terms of the place w here it is used.( 5) One of the main characteristics of groundwater motion is that it occurs at very， sometimes extremely， low velocity. How ever， because of the large cross-sectional areas through w hich this motion takes place，large quantities of w ater are transported. This chapter deals mainly w ith the basic law s governing the motion of groundw ater in aquifers，and w ith the porous media and aquifer parameters. Only saturated flow is considered here. Unsaturated flow w ill be further discussed in Chapter 6. Darcy"s law indicates that groundw ater velocity is directly proportional to the hydraulic gradient.( 6) Salt ( as NaCl only) applied to a highway during the winter for prevention of icing problems has cause contamination of a shallow unconfined aquifer near the highw ay. It has been observed that Cl content of w ater from many domestic w ells，w hich w as formerly soft，has become hard as Cl has risen. The large increase in hardness can be contributed to the effect of road-salt contamination.( 7 ) Many field workers have observed an anomalously large rise in water levels in observation w ells in shallow unconfined aquifers during heavy rainstorm. It is now recognized that this type of w ater-level fluctuation is the result of air entrapment in the unsaturated zone. Air pressure in this zone is much greater than atmospheric pressure. This type of w ater-level rise bears no relation to groundw ater recharge，but because it is associated w ith rainfall events，it can easily be mistaken for it. The most obvious feature is the magnitude of the ratio of w ater- level rise to rainfall. Changes in atmospheric pressure can produce large oscillations in w ater levels in w ells or piezometers penetrating confined aquifers. The relationship is an inverse one; increases in atmospheric pressure create declines in observed w ater levels.( 8) Phreatic aquifers can be replenished from above by precipitation falling directly over the ground surface overlying the aquifer，provided the ground surface is sufficiently pervious. Some parts of a certain area may be completely impervious ( houses，streets，and highw ays or an impervious rock) and do not contribute to the natural replenishment of the aquifer beneath them. Confined aquifers are replenished by groundw ater inflow from an adjacent phreatic aquifer w hich，in turn，is replenished from precipitation. In principle，infiltration is unsaturated dow nw ard flow from the ground surface to the w ater table. The relationship betw een natural replenishment and total precipitation is governed，among others，by the follow ing factors: type of precipitation， climatic conditions， soil moisture prior to storm， storm characteristics， topography of ground surface，perviousness of ground surface and vegetation cover，etc. The natural replenishment of an aquifer can be determined，depending on the amount of precipitation and lithology of the unsaturated zone，etc.( 9) Artificial recharge may be defined as man"s planned operations of transferring water from the ground surface into aquifers. Artificial recharge can be implemented by several methods. The choice of method for each particular case depends on the source of w ater，the quality of the w ater，the type of aquifer，the topographical and geological conditions，type of soil，economic conditions，etc. Artificial recharge can be carried out through injection w ells and surface spreading pits. Artificial recharge plays an important part in augmenting groundw ater resources and in the improvement of groundw ater quality.( 10) However，the depth to the fresh water-saline water interface is underestimated by the Ghyben-Herzberg relation. The exact position of the interface can be determined by draw ing flow -net for steady-state outflow of groundw ater to the sea. On the other hand，the fresh w ater- salt w ater interface is not a sharp boundary but a zone of diffusion mixed w ith salt w ater and fresh w ater. Both the field observation and numerical modeling confirm the necessity of considering dispersion effect in the analysis of seaw ater intrusion. ( 11) There exist many examples of the occurrence of land subsidence of large areal extent as a result of pumping groundw ater. The most spectacular one in an urban area is in Mexico City，w here almost the entire metropolitan area has subsided more than 3 m ( w ith up to 8 m at some locations) . The San Joaquin Valley in California has experienced subsidence at a rapid rate of 30 cm to 40 cm per year，reaching a total subsidence of 9 m at some locations. Other places in w hich significant land subsidence has occurred are Taipei Basin，Tokyo，the Texas Gulf Coast，London and Bangkok. In almost all these places，the aquifers contain compressible clay strata，or a sequence of confined aquifers are separated from each other by compressible clay strata.( 12) Groundwater has an important impact on the generation of landslides. When the slope is w ater-bearing，pore w ater pressure along the potential sliding plane is needed to be determined. If observation w ells have been installed in the slope，the observed hydraulic head， h，can then be converted to pore pressure，p as follow s p = ρwg ( h － z) w here z is the elevation of the potential sliding surface，ρwis the density of w ater，and g is the gravitational acceleration. Pore w ater pressure must be taken into account in the analysis of the potential of landslides.

20以内加减法一般是小学一二年级的数学题，平均每题2秒。所以100题一般规范3-4分钟。如果学生是初学，可以考虑稍微延长做题时间到5分钟。

最近论坛上发了一个连载帖子——吴鉴鹰单片机实战项目精讲，因此受到不少网友的关注，在这里吴鉴谢谢各位网友的支持、关心和信任。 在帖子中留了几个群号，有两千多读者加了群，通过QQ向我询问了很多问题，如果在工作不是太忙的时候我看到了就会回答，但是有时候做项目太忙就没时间解答。 为此，在这里应群内成员以及一些网友的要求，专门写一篇文章来针对这些问题做一个总结。希望能为大家的疑惑有一点点帮助就足以。不足之处，也希望大家客观指出，君子和而不同。1、学习单片机有用吗？ 有很多初学者有这样的困惑，单片机初学者感觉入门很难，学着学着，就会产生这样的疑问——自己辛辛苦苦学习单片机，将来有用吗？ 单片机只是一个工具，重要的还是思想，有了自己的想法，电子行业地域辽阔，随便你闯。单片机这个切入点入手还是不错的，可以让你尽快进入电子殿堂的大门，如果你还在上学，不要眼睛里面只盯着暂时的薪水，哪怕是毕业两三年的也一样。重要的是掌握程度和对技术的理解程度，有句话叫“水到渠成”，到时候再去研究工资的事情也不晚。2、学习嵌入式编程有必要从51单片机开始吗？ 我原本来在读大学的时候，有很多同学听说学习ARM很牛逼，于是就跑到图书馆借了一两本关于ARM的书，学一两天后发现跟自己想的不太像，于是学着学着就慢慢放弃了。所以我总结一下，与其迈很大的步子，不如放慢脚步一步步走。从最基本的做起，一步步走，等单片机学会之后再进行像ARM，DSP之类高端处理器的运用，也就能得心应手了，如果想一口吃成一个胖子，只怕最后没胖起来，倒把自己给噎死了！3、会用高端处理器就牛了吗？ 不少网友问我：是不是学会了ARM、嵌入式操作系统就会很牛？是不是单片机就是运用在低档产品上，ARM做出来的产品就高端了。 首先，从本质上说，是同一类东西，都是嵌入式应用方面的主力。十八般兵器，没有优劣之分，只是在乎持兵器的人修为高低，当年解放军凭借小米加步枪不也取得了抗战胜利。微处理器，单片机、DSP、FPGA、ARM，每一种都有自己的侧重点，都具备自己的优势和劣势。单片机：技术比较成熟，运用在工控领域比较多，但进行嵌入式应用显得太庞大，因而派生出ARM单片机进行高端应用，可以进行操作系统的移植，但是现在一些高端单片机也可以移植操作系统，单片机跟ARM并没有什么本质的区别。DSP：是数据处理的缩写。也可以做控制运用，它的优势是运算，主要用在运算量大的领域，如数字信号处理，图像处理，视屏处理，导弹雷达上也等等。如果要用的好，需要学会很多高深的算法，需要有较强的数学功底。FPGA：可编程逻辑阵列的缩写。实际上就是做一个芯片，用软件实现它的内部连接，达到用软件的方法实现硬件的目标。是用硬件实现的一种方法。是早期单片机（功能简单的逻辑应用）的现代实现方法。总结：一个嵌入式软件工程师，其实核心竞争力不是你会运用什么芯片，当你会了一两种以后，再学其他的，就会觉得很容易了。一个真正的有竞争力的工程师，应该是具备良好的编程习惯，编程思路，还应该具备扎实的数学功底。只有把握核心的东西，才能走的更远。4、单片机行业技术研发有前途吗？ 这也是初学者最为关心的一个话题，单片机行业的技术研发将来前途如何？著名的高尔夫球手，老虎伍兹说过一句话：我只需成为高尔夫数一数二的高手,钱自然会追着我来。 单片机技术研发，也就是一个类型的职业岗位，同样叫做“单片机工程师”，能力、经验、学历，参差不齐，因此待遇肯定也不尽相同。 高待遇者，年薪数百万也有，低收入者，养家糊口都难。 只有倒闭的企业，没有倒闭的行业！ 不是行业没有前景，只能反思自己为何没有足够的优秀。5、单片机技术研发太苦太累，值得去坚持吗？ 在论坛里看到很多人在抱怨：现在电子行业的研发做起来太累，待遇又不是很好，感觉没什么出路。既然我们选择了单片机行业，就坚持做下去，不要轻信别人讲的：单片机研发工程师没有前途，太苦太累。 学好单片机你至少可以找一份技术性的工作，就算目前累一点，至少你可以看到希望，随着自己经验的积累，未来的路会越走越宽！至少可以坐在办公室里面，有自由的时间可以支配。 你知道那种专业课没学好，只能去车间做一线工人的感觉吗？坐在车间里像一个机器人一样每天重复同样的工作吗？你喜欢过那种一点自由都没有，在流水线上忙碌着，连上厕所时间都没有的工作吗？我相信没有人喜欢！ 所有不要被一些工作了几年的工程师的话语所迷惑，说做技术很苦，拿的钱又少，当你真正有一天想去做技术，发现原来因为自己缺少知识的积累，没有公司愿意要你。 简单地分享了自己对单片机领域一些问题的看法，欢迎同行积极分享自己的心得，能让更多初学者少走弯路，摆正心态进行单片机的学习。

第一题的一小题4位的扩展成8位的要进行位扩展，2片一组，16K的存储空间，所以需16组，共需(16K/1K)*(8/4)=32片1K*4的芯片。1片是1K的存储空间，所以需要10跟片内地址线，因为是16组，所以需要4根片选线，采用部分译码，还多余6条地址线，8086有20根地址线，10根片内地址，4根片选线。二小题不需要进行位扩展，只需要进行字扩展，需要512K/8K=64片。一片8K,所以片内地址13根，64片，所以片选6根，同样是部分译码。第二题 我没学过这个模块，不过也可以做，应该是对的。1个模块128K，第一个模块首地址是10000H,末地址是2FFFFH,第二个模块首地址是30000H，末地址是4FFFFH,第三个首地址是50000H，末地址是6FFFFH，第四个是70000H和8FFFFH。第三题。20位的物理地址是如何形成的，用段首址乘以10H,加上偏移地址就是啦。给你解释一下为什么。因为8086是16位机，内部寄存器是16位的，16位只可以寻址64K,但是8086系统的地址线有20根啊，有1M的寻址空间，所以就把整个存储空间分段，每段不超过64K就可以了，段内有一个偏移地址，这个地址是16位的。比如你这题，C018是段首址，FE7FH是段内偏移地址，实际逻辑地址为C018H*10H+FE7FH=C0180H+FE7FH=CFFFFH帮你把作业做完啦，呵呵。你这个家伙好懒哎，计算都帮你做了，我还翻了一下书。我可不是为了分数啊，互相学习啦，呵呵，很开心的。以后这块可以问我，看的出来微机原理你们刚上不久啊，记住我的ID，可以直接问我的。这题不懂得地方可以继续问，我会解释的

好复杂啊 这么多题 一个还差不多

苦了你了，我用的是清华大学的教材，你的那个我没有，微机原理好难啊
