|采纳率93.3%设A,B,C速度分别为Va,Vb,Vc,物体通过AB段与BC段所用时间相同,都设为t
因为AB平均速度=位移/时间=(Va+Vb)/2=L1/t (1)
BC平均速度=位移/时间=(Vb+Vc)/2=L2/t (2)
AC平均速度=位移/时间=(Va+Vc)/2=(L1+L2)/2t (3)
(1)-(2),得到(Va-Vc)/2=(L1-L2)/t (4)
(4)+(3),得到Va=(3L1-L2)/2t,Vb=(L1+L2)/2t
因为Vb^2-Va^2=2aL1
a=(Vb^2-Va^2)/2L1=[((L1^2+2L1L2+L2^2)/4t^2-(9L1^2-6L1L2+L2^2)/4t^2]/2L1

Ishmael is a pleasing character,who plays the role of the main character as well as narrator.He makes up for with a full personality that his described extensively throughout the book.Ishmael is a man who seeks what is best described as “inner peace”.He is very content with himself when on the water,and has a great love for being a seaman.He joins the crew of the Pequod to satisfy his longing to be back on the ocean,but as it turns out,the particular voyage he is to set out on is not what he had suspected.For this ship would be commanded by a half-crazed captain in a desperate search for a viscous white whale.Over all,Ishmael is definitely the most civilized and wise man in the story.1年前查看全部

You look handsome and young!(handsome和young都是形容词,应该是并列关系,用and).I think you are bright and energetic ,with strong career ambition.(bright,energetic 形容词并列,需用and 连接,而with strong career ambition是介宾短语,也相当于形容词,但由于有with,不能与前两者并列使用and)

The above-mentioned irregularities in the structure of a medium may be implied by its continuous nonhomogeneity. However, more frequently they are manifestations of the geometric structure of its interfaces. In the latter case, the class of layered-homogeneous isotropic media with plane-parallel interfaces proves to be most typical and physically expressive. Within the framework of such a class of media, it proves to be possible to elucidate the physical nature of any interference formation in the most distinctive way, to establish the dependence of specific irregularities of wave fields on the frequency band in which the fields are recorded, and also to provide a physically obvious quantitative description of the setting up of interference wave fields that occur both at small and at arbitrarily large epicentric distances. At the same time, such a class of models proves to be the simplest and most adequate for developing methods of a mathematical
quantitative description of interference wave fields. It contains models of media that allow one, in principle, to conduct investigations by mathematically exact methods. Therefore, the results obtained here may be regarded as solutions of the corresponding model problems, and these solutions may be used to extend the methods devised for calculation of fields to both media of a more general nature and to the case of simplified strategies applied in the engineering theory of waves.

《感旧赠故人》*
多少缘尽如一梦,怎解匆匆十载情.
每记山间岳麓灯,常忆雨下湘江亭.
当年语笑蜗庐馨,今此飘蓬任风鸣.
世情大都随流水,肯信明日再聚行.

本诗大意是:人生匆匆认识很多人,可谓有很多缘分,可惜都象梦醒那样不能长久.只有这一段深情保留了10年,不是其他人所能了解的啊.
现在还时常回忆起湖南岳麓山下曾挑灯共读典籍,也曾在湘江边,橘子洲头看湘江的烟雨.
那时候青春年少,常常梨涡浅笑不识愁滋味,如今孤身漂泊只能任凭冷风吹过肩头.
时光逝去一切都如流水不能再拥有,但坚信终有一天我们还能重逢再续此缘.
第一句诗人反起一笔概叹许多逝去不再拥有的缘分,再正写十载缘分忽然能重续的复杂心情.使用了正反手法.
第2句诗人回忆了过去的美好时光,使用了借代的修辞手法,以岳麓灯湘江亭代追忆中的美好时光.
第3句前半句收第2句的美好回忆,后半句启如今的形单影只,形成对比转折,心情从复杂,到欣喜,转到悲伤.
第4句又一转,用相信必有再聚首之时来鼓励自己.
诗人使用大量借代来寓情于景,又使用对比手法来表达复杂心情,“怎解”二字堪称本诗“文眼”.

Vous avez fait des progrès et votre français est ____ qu`avant.

这道题书上答案说应该选A。书上给出的解释是bien也可以作形容词,意为“好的”,通常作表语(如:C`est très bien),其比较级mieux。但是我就不明白为什么meilleur不对,按说bon也是形容词,所以这里是meilleur应该也是对的啊。

A) serait B) soit C) est D) serais

又据题可知:当a=1190时,y=14.1
代入得 14.1=1190*x+26,解得x=-0.01
所以,所设一次函数为:y=-0.01a+26
