Because any reports on the active control of rotating disk haven't be seen in China up to now, and this experiment research is important, so the complete set of active control system of rotating disk are built independently. The push-pull type electromagnet is applied to control the vibration of the circular disk. The power amplifier circuit that can respond to wide scope in frequency from DC to AC is designed by improving the existing circuit. The sensor signal is first low-pass filtered, then the proportional control plus the differential control circuit easy used in practice are applied to finish the more effective control. The electromagnetism shield is used as possible to decrease the signal disturbance from the electromagnet to eddy sensor.

考虑到目前国内尚未见到有关旋转圆盘振动主动控制的相关报导以及实验的重要性，自行设计制作了一整套旋转圆盘振动主动控制系统：提出并采用推拉型电磁作动器来控制圆盘的振动；在改进现有电路的基础上，自行设计了具有较理想特性的驱动电磁作动器的功率放大器；根据实际控制环境的特点，设计了先进行低通滤波，再采用比例和实用的近似微分电路构成的控制器，并采用了电磁屏蔽来减小电磁铁对传感器的干扰，以实现更有效的控制。

Roundness tolerance of pitch diameter Roundness tolerance for a minimum of 345o circumferential arc of the pitch diameter shall not exceed .002 inch (0.051 mm) total, or one half the pitch diameter tolerance if the pitch diameter tolerance is less than .004 inch (0.102 mm); roundness tolerance of the remaining 15o maximum circumferential arc shall not exceed .004 inch (0.102) total, provided such tolerance does not result in excrescence on the thread flank.

The ORF2 gene is the most important protein-code gene for porcine circovirus, and is the main gene differing porcine circovirus typel from porcine circovirus type2 (PCV2). To construct a specific PCR detecting method, we designed a pair of primers to amplify a partial fragment of ORF2 gene from PCV2, referring to fifteen strains complete genome published in Genbank. The PCR product was about 0.67kb in size detected by gelose gel electrophoresis.

猪圆环病毒的开放阅读框2(ORF2)是其主要结构蛋白的编码基因，也是区分猪圆环病毒1型(PCV1)和猪圆环病毒2型(PCV2)的重要基因，本研究参照GenBank已发表的15株PCV2基因序列，设计合成一对引物，对PCV2的ORF2基因进行PCR扩增，产物经琼脂糖凝胶电泳，呈现一条大小约0.67kb的特异条带，经条件筛选，建立了猪病料中PCV2感染的PCR检测方法。

A novel no touch measuring method for traditional products was put forward and a precise model of Direct Linear Transform was presented for the aberration in the images occurred at every turn. Rectangle mark tag and location parameter are no longer needed in this algorithms. A method of tolerance reckon by curve equation was also provided. In order to raise the operation speed Hough circle detection method was improved. In the meantime circle detection method to images with more than one circle was applied, so that the concentricity calculation is possible.
