For the optimization of mechanism design of rolling cut shears, a CAD software of rolling cut shears was developed and was used for the analysis of the factors such as crank radius, link rod length, phase difference, center distance of cranks and the offset position of upper blade carriage, which influenced the cutting quality, strength parameters and the load of main parts.

为了实现滚切剪机构设计的最优化，开发了滚切剪计算机辅助设计软件，利用该软件对影响滚切剪剪切质量、力能参数以及主要杆件受力的曲柄半径、连杆长度、相位差、曲柄中心距以及上刀架偏移量等因素进行了分析研究。

On the condition that the axes of two chain wheels are in the same horizontal plane, the paper considers that the mesh drive of chain and chain wheel is equal to single small angle movement of four-rod mechanism every time on tight side.

在两链轮的回转中心同处一水平面的条件下，视紧边每一时刻链条与链轮的啮合传动为四杆机构作小转角的单向运动，建立起相应的链条速度模型，并据此分析了影响链传动中链条速度波动的因素，得到了一些有益的结

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。

A robust mathematical design model based on the response surface method was established for steering trapezoid mechanism. In the model, movement precision during steering course was chosen as the objective function; kingpins distance, axles distance, trapezoid mechanism's bottom angle and steering arm length were defined as the design variables; minimum transmission angle and maximum angle error were considered as the restraint condition.

对于转向梯形机构，以转向过程的运动精度为目标函数，以主销中心距、轴距、转向梯形底角和转向梯形臂长度四个参数作为设计变量，以最小传动角及最大角度误差作为约束，建立了基于响应面方法的稳健设计数学模型。

Jingan Branch is not even though the defendant, but Oh is still trying to own the legal knowledge to analyze the elusive "shadow hospital": It is not an independent legal entity and should not bear civil liability independently, nor permit to practice medical institutions ; its origins surgeon, nursing staff from the Jing'an District Central Hospital; it does not have an independent operating theaters, medical record room, no drugs, did not check equipment, apart from a director of the department permit brand hang out, it is actually anything NOT.

尽管静安分院已经不是被告，但吴胜则仍试图以自己的法律知识来分析这家难以琢磨的&影子医院&：它不是独立法人，不能独立承担民事责任，更没有医疗机构执业许可证；它的手术医生来路不明，护理人员来自于静安区中心医院；它没有独立的手术室、病案室，没有药品、没有检查设备，除了一个主管部门允许挂出的牌子，它其实什么都没有。
