| | The dynamic theory by which a conventional electrocardiograph can tracing ECG with high fidelity is present by applying automatic control theory and the author's research result on stability theory of multistage feedback amplifiers. The dynamic characteristics of main amplifier is analysed. The stability criteria and the stability margin of amplifiers are given. Moreover, regulations for dynamic design of conventional electrocardiographs and the calculation methods for dynamic parameters are suggested. The... | | 应用自动控制理论和作者关于多级反馈放大器稳定性理论的研究成果,对常规心电图仪能够高保真地记录心电信号的动态理论进行了研究和探讨。分析了主放大器的动态特性,推导了电路的稳定判据和稳定储备计算公式,提出了动态设计的规则和确定动态参数的方法。本文的结论和有关产品的调试结果是一致的。 | | 文摘来源 | | In this paper, the incorrectness of the general mechnical torque calibration equipment that is applied in the production and scientific research at moment is indicated. The simple self-equilibrium type of two-component torque calibration device is advanced. The cross talk of calibration process is eliminated. The precision of measurement is increased. This equipment can be used for the eleme- nts of the lathe(the type of C620 or C630). It is very convenient and economical. | | 本文指出了当前在科研和生产中采用的一般机械式扭矩加载器的某些缺点和错 误;提出一种自平衡式单臂双用纯扭矩加载装置,可以消除定标过程的附加干扰,保 证检测精度。该装置简单,合理、适用。 | | 文摘来源 | | In this paper, a method to extend the functions of single beam GDM 1000 monochromator has been reported. Softwares have been used to compensate the errors resulting from the fluctuation of light source on the basis of adaptive noise cancelling principle and widrow's LMS algorithm(the maximum error in transmission measurements is ±0.005T). The computer linking hardwares are very simple and all softwares are written in BASIC Language. The method is of high adaptability. The computer linked system while preser... | | 本文报道了一种用AppleⅡ微型计算机与GDM1000单色仪联机实现分光光度计功能的方法,并根据自适应噪音消除器的原理及Widrow最小二乘方算法,利用软件来补偿由于光源不稳所引起的误差(用于透射测量的最大偏差为± 0.005T)。联机系统保特原有高分辨率(0.5cm~(-1))和高波数精度(2cm~(-1))的优点,可用于测量透射谱、吸收谱、反射谱,可进行谱线累加从而提高信噪比,还能很方便地得到微分谱提高分辨能力。文中还给出一些应用的实验结果。 | | 文摘来源 | |   | | << 更多相关文摘 |
