一前一后

It barred the vast opening of the faubourg, that is to say, three streets, from angle to angle; ravined, jagged, cut up, divided, crenelated, with an immense rent, buttressed with piles that were bastions in themselves throwing out capes here and there, powerfully backed up by two great promontories of houses of the faubourg, it reared itself like a cyclopean dike at the end of the formidable place which had seen the 14th of July.

它挡住进入那一郊区的一大片岔路口，就是说，从这端到那端，它连续遮拦着三个街口，忽高忽低，若断若续，或前或后，零乱交错，在一个大缺口上筑了成行的雉堞，紧接着又是一个又一个土堆，构成一群棱堡，向前伸出许多突角；背后，稳如磐石地靠着两大排凸出的郊区房屋，象一道巨大的堤岸，出现在曾经目击过七月十四日的广场底上。

I'm not sure how it started -- I think I probably just collapsed one evening after chasing a preschooler and a toddler all day.

我不知道什么时候开始这么做--我想大概那是有一天的晚上跟在一位学龄前一位刚学会走路的孩子后面追逐了一天后开始的。

Results showed that the RFAs in DCS of Masson pine CTMP were mainly composed of oleic acid,linoleic acid,DHA,pimaric acid,abietic acid and oxidized products of DHA.The ratio of fatty acids to resin acids in FR-DCS,CTMP-DCS,BCTMP-DCS were 1:2.8,1:2.1 and 1:3.8,respectively.

结果发现，马尾松化机浆DCS中的脂肪酸主要有油酸、亚油酸等，树脂酸主要有脱氢枞酸、海松酸、枞酸以及脱氢枞酸氧化物等；一段磨后浆、漂前浆、过氧化氢漂后浆DCS中脂肪酸与树脂酸的比例分别约为1：2.8、1.2：1、1：3.8。

Firstly, on the basis of summarizing the research results, this paper deeply discusses the calculating model to analyze the instantaneous motion state in vehicle collision and the interrelation between restitution coefficient and vehicle collision speed. The simplified Gim tyre model is introduced, this type model has the fast computing and higher calculating precision, it is the practical vehicle type model in the analysis of vehicle collision accident at present. According to the collinear collision and two-dimension collision, the paper establishes the impact model at vehicle collision moment and the post collision movement model.

本文在总结前人研究的基础上，分析了车对车碰撞作用瞬间状态的计算模型及碰撞恢复系数与碰撞前、后速度的关系：介绍了Gim轮胎理论模型的简化形式，该模型计算速度快、计算精度高，尤其在车轮大侧偏角运动时其计算精度远远优于其它轮胎模型，是目前在汽车碰撞事故分析中最为实用的汽车轮胎理论模型：根据交通事故中最普遍的一维碰撞和二维碰撞的不同情况，分别建立了碰撞作用瞬间的力学模型和碰撞后车辆动力学模型。

The steps are as the following:1、Preparing the cerebrospinal fluid one hour before the experiment,take some of them for cryopreservation;2、Without paralyse,cuting down the rat head quickly and dislodge the hippocamp part which is used in the experment in freezing liquid,and trim the hippocamp distrct.3、Fixing the hippocamp tissue on the vibratome,to cut down a brain slice with 300μm,use the haustorial tube to move the slice to the preincubate dish,cultivanting it for one hour.Then move it to the record incubation chamfer.4、Preparing the glass micloelectrode and fill it with NaCl,the corcentation is 3mol/L.5、adjusting the recorder,after cultivate the brain slice in the incubation chamfer for 2 hours,the expermentize can be gone on.6、In order to ensure the accurate of the experimental result,use only one medicine concentration for one brain slice in every experiment.

本实验研究方法是：1、实验前1小时配制好所需脑脊液并充以95% O2和5% CO2的混合气，取小部分冷冻保存；2、在乙醚麻醉下，快速断头并在冷冻液里取出包含海马的大脑部位，修整出所需海马区；3、将海马组织固定于振动切片机上切出300μm厚的海马脑片，用广口吸管转移至预孵育皿培养一小时，后再转移到记录用孵育槽内；4、拉制好玻璃微电极，并充以3mol/L的NaCl；5、调试好记录仪器，将脑片在孵育槽内培养2小时后进行实验；6、为了保证实验结果的准确性，每一块脑薄片只进行一个浓度的药品实验。

Robert Audley's heart sank within him as the shabby hired vehicle stopped at a stern-looking barred fence, and the driver dismounted to open a broad iron gate, which swung back with a clanking noise and was caught by a great iron tooth planted in the ground, which snapped at the lowest bar of the gate as if it wanted to bite.

罗伯特·奥德利的心往下一沉，当破破烂烂的马车停在面目冷峻的铁栅栏前的时候；马车夫下车推开一扇宽阔的铁门，铁门哐啷一声向后晃动、撞在埋在地里的一个铁牙齿上，铁牙齿扑在铁门的最低的一根铁条上，仿佛要咬它似的。

In this paper the size of the crank-slider mechanism is synthesized,and the point location is correctly selected for the six-bar linkage mechanism.

对于这种轨迹串联的组合机构，由于后一基本机构的运动，取决于前一基本机构中从动件的轨迹，要求连杆上M点作一过从动件的固定铰接点D的一段直线，从而使构件DM可以作间隙的旋转运动。
