At the same time , combining the electrostatic measurement principle and the actual working conditions of pneumatic pipelines , the author puts forward the design principle in theory and finishes the devising , executing , debugging , experimenting and analyzing the experiment phenomena and results , testing the feasibility of the electrostatic sensor to be used in the measurement on the mass flow rate of the coal paniculate . furthermore , with the debugging and experimenting of the system , the author improves the electrostatic sensor and its signal collecting system gradually according to the problems , and makes the performance of the system to be enhanced remarkably 同时，作者结合静电测量原理以及气力输送管道的实际工况，从理论上提出了静电传感器的设计依据，完成了静电传感器及其信号采集系统的设计、制作、安装、调试和实验，分析了实验现象和结果，验证了静电传感器用于煤粉质量流量测量的可行性，并且通过系统调试和实验，针对发现的问题对静电传感器及其信号采集系统不断地进行了改进，使其性能有了显著地提高。
The way to control some equipment cells different from standard by the standard control cell is introduced . as a practical , the pulse nitrogenous conveying control system in yueyang chemistry factory is achieved by configing and assembling the four standard control model cells and extending a new control station for packing contailer . for its characteristic of centralized supervision , real distributed control and the high ratio of capability to cost , the control system is high praised 并通过组态集成这四类控制模块，成功地实现了岳化氮保护脉冲气力输送控制系统，并扩展了其中的包装仓设备单元控制模块，实现了真正的集中管理、全分布式的控制，具有很高的性能价格比，获得了用户的高度评价。
On the base of the analysis on the advanced technology of hard ferrite in foreign country , the main procedures of preparing hard ferrite pre - sintering material are determined as follows : first , the ferrite oxides coming from the main cold rolling line and strontium carbonate are conveyed to storage tank by gas power and weighed automatically according to the demands of constituent composition . and then they are mixed and grinded by using method of wet treatment . finally the mixtures is transported to the devices of storage by transporting pump 在分析国外先进的永磁铁氧体生产工艺的基础上，确定了生产高档永磁铁氧体预烧料的主要过程：首先，利用攀钢冷轧铁红为主要原料，将氧化铁红及碳酸锶采用气力输送至贮料料仓，经自动称量装置，按工艺配方称量后分别由氧化铁红及碳酸锶发送罐气力输送进入预混搅拌筒加水搅拌，然后再送入混磨机湿法混磨；最后，混合物经输送泵输送至料浆存储装置，经定量进料泵定量输送至回转窑进行湿法预烧，预烧料经缓冷至室温后，再球磨。
