查询词典 used to

To improve the accuracy, as to the hardware, the quality of composite polymer films and adjustment of light path were controlled strictly, including cleanout of base, synthesis of solvent, filtering of solvent, preparation of the films and control of picturing. As to the process of picturing, adding gauge, foreground and background, many exposals in same angle were used, and the area of the films to measure was also chosen. As to software, picture analysis was mainly used to improve accuracy.

Even if you have such as Li Shang-yin "on behalf of gifts" described in verse:"do not show banana clove hitch, with their worries to the spring breeze", thefull heart, can have "My family lived on the shore, listening to the number used to sub- boatman to see the white sail boat used to ......"

即使你如李商隐《代赠》诗描述的："芭蕉不展丁香结，同向春风各自愁"的话，满满的心，可有"我家就在岸上住，听惯了艄公的号子，看惯了船上的白帆……"可悄悄为你缱绻，这怎能不让罗德尼娜这位"苏联的国宝"等资深人才叹为观止？

As a result, it shows thatthe static or dynamic subsystem optimum alone is not equal to the system optimum. Three initial value problems met in the optimal design of flying vehicle are studied andconclusions are derived that: orthogonal test method can be adopted to decide the initial valueof static optimization problem, some mathematical techniques can be used to deal with thecostate variables of Maximum Principle and decide the initial value of the costate variable,the indirect method can be used to get the analytical solution under ideal case to guide thechoice of the initial control curve in the direct method. With some numerical examples oftrajectory optimization, it shows that all these methods are useful not only in accelerating theconvergence but also in converging to the global optimum.

针对飞行器优化设计中的三种初始值问题进行了研究，以远程弹道导弹弹道的工程优化为例说明，对于静态优化问题，采用正交试验法选取初始值，不仅可以大大加快收敛的速度，而且更有可能收敛到全局最优解；以气动力辅助变轨问题为例说明，用共态变量的一阶泰勒级数展开可以解决极大值原理中共态变量初值难于确定的问题；以二级弹道导弹的主动段弹道优化为例说明，利用间接法在理想情况下得到的解析解来指导直接法初始控制曲线的选择，将大大有利于提高直接法的收敛速度。

The electronic heating evaporator in the high-side gravity recirculation system in ANSI/ASHRAE 64-2500 standard is replaced by a new type plate evaporator which is more effcient and energy-saving, because the cold water outlet from the evaporator that is used to heat the cryogen can be used once again to cool the air in the air inlet trunk; an air processing unit is designed in the lab design, so to imitate all kinds of weather in each season in every location of China at any time the test is being made; the data selection system can send all the data in the test to the computer at one time, and to reduce the cost of the test some data which is more stable are read manually through traditional meters if this can not sacrifice the precision of the test.

本文的设计中用效率更高的新型板式换热器代替了原ANSFASHRAE 64——2500标准中压缩驱动循环系统中的电加热蒸发器，加热冷剂后得到的低温淡水还可以用于冷却进气通道中的空气，不仅提高了效率，而且更加节能；实验室方案中增加了空气处理系统，可以实现随时对全国各地各季节的空气状态进行模拟，方便实验的进行；采用数据采集系统将数据整体采集到电脑中方便数据处理，而且对于变化频率不高相对较为稳定的数据采取传统仪表进行人工读数，在保证测试结果准确性的前提下降低了成本。
