Based on AC servomotors, NC Heavy Duty Mechanical Driving is a combination of new and high technology (information technology, auto control, modern electrotechnics, new material, etc.) and traditional mechanical technology.

基于交流伺服电机的数字化重载机械驱动技术，是高新技术(信息技术、自动控制、现代电工、新材料等)与传统的机械技术的结合。

It is: sets the RFID label on the hanger, the card reader can get the information of the label and sends to the epigyny of the terminal unit of the station; when the hanger passes the reader of any working station; estimates the hanger whether or not enters the station to process manufacture after the epigyny receives the signal of the hanger, the programmable logic controller controls the pulling-in switch of the corresponding station according to the instruction from the epigyny.

该方法包括：在吊架上设有RFID标签，当吊架经过某个工作站进站口前的RFID读卡器时，读卡器会读到吊架标签上的信息，经由工作站终端设备发送给上位机；上位机接收到吊架检测信号后，判断此吊架是否进入工作站进行加工，可编程逻辑控制器根据上位机的指令控制相应工作站点的进站开关合上。

From dynamic customer demand, supply chain is composed of supplier and retailer, combining P-control strategy with z-transformation, a dynamic model is given, building model of traditional, EPOS, VMI supply chain respectively.

研究在动态顾客需求下，生产商和零售商所组成的供应链系统，采用P-控制策略和z变换相结合，给出一个动态模型，并分别对传统、EPOS和VMI供应链进行建模，通过仿真，分析和比较顾客需求信息对三种供应链性能影响的效果。

With the theory, any straight lines and quadratic curve′s equidistance curve can be indirectly interpolated with the help of outline and wire circle′s information, it is unnecessary to calculate equidistance curve .

该理论直接利用轮廓曲线和丝圆的信息，不需计算等距曲线，间接实现任意直线和二次曲线的等距曲线的插补，有效地避免了传统计算等距曲线产生的计算误差，简化了数控机床控制程序设计，提高了机床的控制精度。

The method controls the move of head flying over the disk by firmware and analyzes the width change of projection of the read head, write head and erase band. The experiment shows skew angel can change off-track capability of magnetic head and change the radial error propagation of radial error of self servo-writing.

分离式磁头对硬盘驱动器伺服信息自刻写的影响同样不容忽视，为此提出了一种测定磁头偏移磁道能力大小的方法：通过控制磁头飞行过程，并在飞行过程中动态获取读头信号幅度和比特误差率，从而获取磁头磁道偏移能力。

噪声控制或利用噪声源信息对机器进行工况监测和故障诊断，首先必需识别噪声源信号。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
