Students of the tin shui wai government secondary school , the senior champion team , explaining how their rain gauge works 高级组冠军天水围官立中学的同学在介绍他们的雨量计操作原理。
The wind profiler works on the principle similar to that of a radar by sending out pulses of electromagnetic waves vertically upward into the atmosphere 气流剖析仪的操作原理与雷达相类似，两者都是向天空发出电磁波脉冲探测大气。
To measure the rate of rainfall , the jardi rate - of - rainfall gauge operates on the principle that the position of the float in a collecting chamber is proportional to the rate of inflow of water 天文台以查迪型jardi降雨率测量器来量度降雨率。该测量器的操作原理在于集雨室内浮子的位置高低与水的注入率成正比。

Based on the second development method of pro / e ， developed the eular elements operation library and the form feature library in pro / e environment ， and achieved preliminarily the 3d local operation of the form feature model 深入分析了局部操作原理及实现机制，归纳了pro / e二次开发方法并以其为平台，开发欧拉算子库，初步实现了三维模型的局部操作。
This paper provides the coding schemes of harq and the protocols of limited times packet retransmission . especially , the analysis of performance and the mechanism of operation of the n - channel stop - and - wait protocol are given in detail 本文针对hsdpa的目标，围绕harq技术进行研究，给出了harq的编码方案以及有限次的分组重传协议，并对其中的n信道停等协议saw作了详细的性能分析及操作原理说明。
It works like this : if a request to load an infected file comes from a network , an automatic action is taken and nothing is displayed . on the other hand , when the request comes from a local or terminal session , the usual interactive mode is used - as in desktop antivirus 告,它的操作原理是:如果网络请求加载一个被感染文件时,不会显示警告,另一方面,如果本地或者终端会话发出加载请求时,使用互动模式-像单机版一样
This paper designs a practical system of 3d roadway visualization under the platform of computer , which is based on the research and development of the project of gis institute of xi ' an university of science and technology named mine information and drawing system , and analyzes the operation principle of opengl at length , and makes a research on real expression of 3d roadway 本文结合西安科技学院地理信息研究所的项目“煤矿信息与绘图系统”的研制与开发，在详细分析了opengl操作原理的基础上，论文对三维巷道的真实表达进行了研究，设计了一套微机平台下的实用巷道三维可视化系统。
There are many methods for measuring impedance and commercial lcr meters may have very different working principles . it is more advisable that customers submit their impedance standards for calibration , which in turn can be used to perform in - house checking of their lcr meters . however , the laboratory may offer performance checks for lcr meters using impedance standards 测量阻抗的方法有多种，故此市面上的电感电容电阻计或有截然不同的操作原理，一种比较适当的做法是客户将其阻抗标准器送来本所校正，然后客户可利用这些已校正的标准器替自己的电感电容电阻计进行测试。
Second , based on the advantages of the traditional transaction reduction methods and the defects of the transaction reduction technique in dhp algorithm , an optimized transaction reduction technique is proposed and at the same time its operational principles and realizable steps are analysed and studied in detail 事务压缩技术部分在集合传统压缩方法优点的基础上，针对dhp算法中事务压缩技术的不足，提出了更优的事务压缩方法，并对该方法的操作原理和实现步骤进行了详细地分析和研究。
