The definition of generator angle is proposed in this paper. A new method to deduce generator angle by using rotor rotation signal is illustrated, which compares the phase difference between GPS timing pulse and RRS. Using only mechanical signal, the technique unfreezes limitation of zero-cross of generator terminal voltage during transient process. Automatic correction of initial generator angle is also proposed .

本文介绍了同步发电机绝对转子角的定义，提出了一种测量绝对转子角，进而获得高精度的相对转子角的方法；此方法不使用机端电压过零整形脉冲，而是将机组键相脉冲与GPS 定时脉冲比相，并能够自动整定初始位置角，因此，测量结果不受发电机运行状态的影响，能够在各种运行方式和扰动情况下获取高精度的绝对转子角。

To evaluate the variability of repeated QT dispersion measurements and the range of normal value,simultaneous standard 12-lead surface electrocardiogram tracings were obtained in 100 normal subjects and 50 myocardial infraction patients.The reproducibility of QTd was assessed with different paper speeds and the normal rangs was analysed.

为评价QT离散度测定的重复性和制定正常值范围，采用同步十二导联心电图机测量100例正常人和50例心肌梗死患者的QTd，分析QTd在不同纸速时测量的重复性情况，以及测量QTd正常值范围。

The paper is based on rotational parts of a kind of Screen Press machine tool. In order to guarantee the kinematics precision and stability of large rotational part, the technology of dual servo motor synchronous dive is adopted instead of conventional hydraulic servo drive.

文章以一种屏压机的转台及其传动机构为研究对象，为确保该大型回转部件的运动精度和平稳性，采用以双伺服电机同步驱动取代传统的液压伺服驱动的设计方案。

At last, based on the methods above, a PROFIBUS-based networked motion control prototype system and a CANopen-based networked multi-axes motion control system of shearing machine were realized.

最后，基于上述方法，完成了基于PROFIBUS的网络化运动控制原型系统和基于CANopen的剪板机网络化多轴同步控制系统的开发。

At the same time, also owns the world's most advanced production equipment, such as: Germany LEMANN company's eight production lines gravure ink, Switzerland BUHLER Topas9000sc company's two production lines and key equipment used computer-controlled all the sanding machine K-120, and also Sync with the British company ink, Spain chemical plastic packaging gravure ink used in polyurethane adhesive technology, real set by the company, industry and trade integration.
