For improving the maneuver stability,safety and decreasing the tire wear,the combination of the optimization software,modefrontier and msc.adams,is applied to design the steering mechanism,with bottom angle of steering trapezoid,arm length,kingpins distance and axles distance as design parameters,transmit angle as constraint,minimum error between theoretical and practical steering angle as objective function,and simulated annealing as the optimization algorithm.

为了提高汽车操纵稳定性、安全性及减少轮胎磨损，将数值优化软件modefrontier同机械动力学仿真分析软件m sc.adam s集成，以转向梯形底角、转向臂长度、主销中心距和轴距为设计参数，传动角为约束，以转向时内轮实际转角与理论转角的误差最小为目标函数，采用模拟退火算法对转向机构进行最优化设计。

To ensure a secure connection between the arm and the disc nut, split pin is used.

为了确保臂杆和阀瓣螺母之间的安全连接，使用了开口销。

Based on the six-wheel mobile robot, research on the robot tumbler joint transmission device has been done. Through comparing various transmission devices, the RV transmission mechanism is studied.

本文以六轮腿自主移动机器人作为研究平台，重点对机器人转臂关节传动装置进行了设计研究，在比较多种传动装置优缺点的基础上，采用RV传动机构作为研究对象。

The upper arm angles slightly backward from point of shoulder to elbow, and is never perpendicular to the ground.

前臂与呈略微直角，臂有一个略微向后的角度，并且决不垂直于地面。

This will create a good shoulder rotation if both arms are moving in the same direction.

这样两臂同向运动会形成好的转肩。

In the instant of touchdown of the left foot, the angle between shoulder and hip was 58°, the angle of pull was 136°, the angle of axis between shoulder was 19°, the speed of left shoulder was 3.49 m/s, the speed of right shoulder was

①腾空阶段，拉引角变化幅度大，投掷臂并没有随身体向投掷方向转动，而是向后主动用力，这可能是发生肩锁关节扭伤脱位的重要因素。

The relationship of three Brachionus calyciflorus morphotypes (two short-spined, single-spined and spineless ones) was studied in the laboratory.

在实验室条件下研究了萼花臂尾轮虫3种形态型(双短侧棘刺、单短侧棘刺和无侧棘刺)个体之间的关系。

Methods Three adult rat models were set up, including the model of total left brachial plexus root avulsion injury, the nerve transfer model of contralateral seventh cervical nerve root to median nerve, as well as the callosotomy model.

结果： 1、成年大鼠全臂丛根性撕脱伤后：（1）在双侧SmI记录SEP：不同时间段电刺激患爪正中神经支配区，在双侧SmI 均未诱发出SEP；电刺激健侧前爪正中神经支配区，在健爪同侧SmI未记录到SEP，只在其对侧SmI记录到SEP，且不同时间段的SEP位点数目均明显多于正常对照。

Objective To study the protective effects of Schwann cell derived neurotrophic factor on motoneurons of spinal anterior horn from spinal root avulsion induced cell death.

目的 研究雪旺细胞源神经营养因子对臂丛神经根性撕脱所致前角运动神经元死亡的保护作用。

It extends your reach by five feet [1.5 meters], making it that much easier for someone to haul you back into the raft—always the preferred option.

它把你的臂展伸长了 5 英尺（1.5 米），使别人能容易得多地把你拉回筏子——这永远是首选。

Do you know, i need you to come back

你知道吗，我需要你回来
