详细地说明了磁传感器在开发中的两种方案与电路原理。-Detailed description of the magnetic sensors in the development of two programs with the circuit principle.

数字频率计的设计可以分为测量计数和显示。其测量的基本原理是计算一定时间内待测信号的脉冲个数，这就要求由分频器产生标准闸门时间信号，计数器记录脉冲个数，由控制器对闸门信号进行选择，并对计数器使能断进行同步控制。控制器根据闸门信号确定最佳量程。-The design of digital frequency meter can be divided into measurement and display count. The basic principle of its measurement is calculated under test signal within a certain period of time the number of pulses, which have a standard requirement by the divider gate time signal pulse counter records the number of signals from the controller to choose the gates and counters to make off synchronous control can be carried out.Controller based on the gate signal to determine the optimum range.

一篇介绍自动调焦用于生物显微镜的英文章，包括其总体结构。-The bioengineering is a popular and fast-developing researching topic in recent years. Among them, the observation of microorganism is a very important experimental approach of bioengineering. As the biological sensing chip technology becomes mature, it is even beneficial to the research. Most of the biological sensing chips for measuring and observation adopt different type of precise microscopes and the corresponding software.
