Seven cars of a freight train in Washington have derailed over the Anacostia River. A Fire Department official says there are no injuries and there is no cause for concern.

一辆货物火车的7节车厢在华盛顿Anacostia河上方脱轨，一名消防官员表示事故中没有人受伤，事故原因尚未确定。

In Chapter 19 we will analyze how well-positioned Android is in the mobile space.

在第19节我们将分析如何能在Andorid移动空间中找准好的位置。

Group one received 0.375% bupivacaine;Group two 2.5% chloroprocaine;Group three in which 1:200 000 adrenaline was added to 2.5% chloroprocaine. Anesthesis was performed by interscalene brachial plexus block.The onset and duration of analgesia,the level of block as well as adverse effects were recorded.

肌间沟法行臂丛神经阻滞，观察阻滞起效时间及持续时间、神经阻滞节断数、术中镇痛质量、不良反应以及注药前、注药后5、10、30、60分时心率和平均动脉压。

And linking the principle of choosing computer visual inspection system hardware, the paper constructs hardware structure of visual inspection system, and develops measure software of thread geometry parameter and applies all above research results to quantificationally measure geometry parameters such as half angle of thread, coning and pitch of conical joint screw thread of graphite electrode, at last educes influencing expressions of the shelter of lead angle to half angle of thread change, it establishes theory base for error amendment.

论述了微小零件尺寸及形状误差的常用测量方法，提出了将视觉检测技术应用到微小零件尺寸及形状误差的测量中，构建了视觉检测系统的硬件结构，开发了相应的测量软件，应用第三章介绍的各种边缘检测方法对传动用滚子链链板进行了边缘检测对比实验，找出适合的边缘检测方法，并应用上述各章的研究结果对传动用滚子链链板节距以及圆形零件的圆度误差进行了测量。

It is helpful to think of "angular displacement" as having a direction of translation attached with it.

之所以说"数学上"等价，是因为在本节中，我们会对"方位"，"角位移"，"旋转"作精确的区分。

Any of various annelid worms of the class Polychaeta,including mostly marine worms such as the lugworm,and characterized by fleshy paired appendage s tipped with bristles on each body segment.

多毛目环节动物多毛目中的任一种环节动物蠕虫，主要包括海生蠕虫，如海蚯蚓，特征是其身体的每一节上都长有尖端带刚毛的、多肉的成对附属物

A three-dimension FEM model of normal L4-5 was built, and the lumbar facet joints were treated as to contact with each other. Various motions of L4-5 were simulated by changing the loads: anteflexion, retroversion, right rotation, right bending and longitudinal compression.

本文建立了L4-5正常运动节段的有限元模型，将两小关节面处理为接触模型，分析了小关节面在腰椎前屈、后伸、侧弯、旋转及压缩运动状态下的受力情况，发现小关节在承载方面作用较大，特别是抗旋转运动过程中作用更明显。

Ajax son of Telamon was more angry than any, for the man had fallen close be, him; so he aimed at Polydamas as he was retreating, but Polydamas saved himself by swerving aside and the spear struck Archelochus son of Antenor, for heaven counselled his destruction; it struck him where the head springs from the neck at the top joint of the spine, and severed both the tendons at the back of the head.

他当即 投出闪亮的枪矛，对着回退的普鲁达马斯，但后者迅速跳到一边，躲过了。。幽黑的死亡――枪尖吃中安忒诺耳之子阿耳开洛科斯，永生的神祗注定他必死的命运。枪矛扎在头颈的交接处，脊椎的最后一节，切断了两面的筋腱；所以，倒下时，他的头、嘴和鼻子抢先落地，远在腿和膝盖之前。

The effects, of protection and treatment with, combined Ch, NaF and a trophie were significantly better than that with atropine alone. In isolated phrenic nerve-diaphragm preparation of rat, isolated jejuneal preparation of, guinea pig, and the metabolic experiment of rat liver, the results of the, assay on the rat blood ChE activity indicated that antidotal effect of NaF may be due to the antidese...

大鼠离体膈神经膈肌、豚鼠离体空肠和大鼠肝脏代谢实验及对大鼠全血胆碱酯酶活力测定的结果表明，NaF的抗毒作用可能是由于其对神经肌肉接头和/或神经节中的N受体的抗脱敏作用；而Ch则可能通过其对ChE的保护和/或加速被抑制ChE的复能，阻碍Ach到达M受体部位而发挥作用。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
