A arming control system of synchronous fitting missle is brough forward in this paper of which the arming control unit composes of the high speed digital signal processing chip dsp and fpga , and has better performance in speed and precision 本文提出了一种双联装导弹瞄准系统，其瞄准控制部分由高速数字信号处理芯片dsp和现场可编程门阵列fpoa构成，使得整个系统在速度和精度方面都具有较好的性能。
The contradiction between high speed and miniaturization of the system is settled by using dsp . the arming controller of the arming control system of synchronous fitting missle based on dsp is developed which aggregates high speed , high precision and miniaturization 利用dsp ，研制出集高速度、高精度和小型化于一体的基于dsp的双联装导弹瞄准系统的同步瞄准控制器，解决了系统高速度与小型化方面的矛盾。
The water quality of the production plant is analysed , and it is held that the procreation and development of srb and the presence of sulphide are main causes leading to the instability of the injected water quality . the measures are put forward for improving the injected water quality 通过对采油厂双联注入水水质的调查分析，发现srb的生长繁殖和硫化物的存在是导致注水水质不稳的主要原因，并提出了改善注水水质的相应措施

They enable the concretization and manipulation of the strategy for the external opening . the combined strategy of the " combination of the external opening and development " turns into sub - strategies of important products export , utilization of foreign capitals and frontier trade etc . this chapter expounds each sub - strategy on their advantages , problems and strategic measures 西部地区“开发与开放”双联战略中较为重要的是产品出口、利用外资，边境贸易等分战略，本章对每一分战略都基本上从有利方面，存在问题和战略措施三个角度进行论述。
First , the basic theory of static load sharing mechanism has been presented , mainly including manufacturing and assembly error of each gear component ' s axis and each bearing ' s axis , gear size ( tooth thickness ) errors , simultaneous error of middle two - tooth . the formula of equivalent mesh error has been deduced , the load sharing coefficient has been computed . second , the influences of each error on the static load sharing coefficient have been discussed 首先，从静力学的角度研究了星型齿轮系统均载的基本原理；确定了影响齿轮系统均载特性的制造和安装误差，主要包括：各个齿轮构件的中心轴线制造和安装误差、轴承中心轴线的制造和安装误差、齿厚偏差、双联星轮同时啮合线误差；推导了这些误差的当量啮合误差的计算公式，分析了系统的均载特性。
Applying the theory on hydrodynamics and combining the structure of the pump , the method of calculating the flux is found , using the simulating dual pump which mercury serve as the working medium , by the experiment on the electromagnet used in the dual pump , the optimum method of the coil connection is gained ; by the experiment on the relation the static pressure and the working parameter in different groove structure , a high - efficiency groove structure named as " + " shape are devised ; by comparing the static pressure and flux between single pump and dual pump , the conclusion that the flux of dual pump is about 1 . 6 times as much as the flux of single pump is educed , and prove it practical that the dual pump is adopted to increase the flux 利用水银为工作介质的双联电磁泵，通过对双联电磁铁不同接法的实验研究，找到最佳激磁线圈接线方法；通过对不同流槽结构的静压头与工作参数关系实验，研究得出一种高效率的新型流槽结构? ?十字型流槽结构；通过对单泵、双泵的泵高和流量实验，得山了在同等工作条件下，双泵流量大约为单泵的1 . 6倍的结论，从而证明了采用双联泵的方法来提高直流电磁泵的方法是切实可行的。
