The last part of the thesis summarizes the design plan of this system . comparing with the current airfield light dimmer control system , the application prospect of this system is pointed out 论文的最后部分全面总结了该系统的设计方案，并与现行的机场调光系统进行比较，指出了该系统的应用前景。
Because the airfield light dimmer control system has operating fast , reliable characteristics during switching over the light grade , the designs of systematic software and hardware are all around these characteristics 由于机场调光系统对切换光级的速度和系统可靠性有特殊要求，所以系统的软硬件部分都是围绕着这两个特点进行设计。
At last , considering of the need of the subject of blue - light system , we analysed and compared the diference of the performance ofthe ethernet interface and the sata interface , and on the base of the existing information , we got a conclusion provisionally 最后，由于课题蓝光系统的需求，得出了以太网接口与sata接口性能比较分析，并在已有的条件和知识下，初步得出了结论。
In this system , we employed a newly developed multi - channel photodetector - ccd ( charge coupled devices ) , as well as a concave holographic diffractive grating , to form multi - channel splitting system of spectrum - polychromator . these all solidified the foundation of the fast measurement subsequently 在本系统研究中，采用新型的多通道光电探测器件? ?电荷耦合器件( ccd ) ，并引入平场凹面光栅构成了多通道光谱分光系统? ?多色仪，从而为多通道快速光谱测量准备了物质条件。
How to improve the three primary colors led light source cavity , polarizing beam splitter system of civil lcos hmd is discussed in this paper . in addition , a new eyepiece optical system with wide fov ( field of view ) 、 big exit pupil 、 long eye relief is also designed by an optical design program named zemax . the result is very successful 本文对民用lcos头盔微显示器的led三基色光源及其腔体、偏振分光系统进行了改进,借助zemax光学设计软件辅助设计出了大视场、大出瞳直径、长出瞳距离的目镜放大光学系统,获得了十分理想的效果。
The results of treatments with different concentration of phosphate in the present study indicated , whether boea leaves were treated before desiccation or during rehydration , and whether they were intact leaves , leaf halves or leaf discs , the boea leaves were injured and their photochemical activity of psii were serious affected by treatment with 0 . 1mol / l phosphate or over , thus resulted in poor resurrection for dehydrated boea leaves . the photochemical activity of psii was a sensitive parameter of physiological activities for boea leaves during dehydration and rehydration 本文利用不同浓度的磷酸盐溶液处理牛耳草叶片，结果发现，不论是在干燥前还是在复苏时处理，也不论是处理牛耳草整叶、半叶还是叶圆片， 0 . 1mol l以上的磷酸盐溶液都对牛耳草叶片具有损伤作用，极大的影响了其光系统的光化学活性，使得牛耳草叶片在脱水后不能很好的复苏。
The electron transport rates of chloroplasts were depressed after chinese cabbage and mustard had been infected with tumv , whose extents reached 6 . 4 % and 64 . 6 % respectively . the decline of photosystem ii ( psii ) activities mainly contributed to the drop of electron transport rate , whose degrees reached 56 . 9 % and 34 . 3 % , with the statistical result p < 0 . 01 青菜和芥菜叶绿体电子传递全链的电子传递速率各降低6 . 4和64 . 6 ；光系统( ps )的电子传递活性各下降56 . 9和34 . 3 ，与健康对照的差异水平均达到极显著；光系统( ps )的电子传递受抑程度较轻，分别为25 . 8和24 . 7 。
When passed through the beam - splitter , a pulsed laser beam was split into 3 beams with an interpulse delay of 13 ns . these 3 separated laser pulses reach the m - z interferometer at different time and each laser pulse gave a snapshot of the implosion state . thus three different - time interferograms can be obtained in one shot of z - pinch 激光器发出的光束经过分光系统被分成时间间隔13ns的三束光，它们于不同的时刻先后到达m - z干涉仪，每一束激光脉冲可以记录下等离子的一个状态，从而可以得到三幅不同时刻的干涉图。
Photosynthesis is the unique function of higher plants , green algae and cyanobacteria , which is the greatest turnover powered by light energy on our planet . psii functions as a water / plastoquinone oxidoreductase in the thylakoid membrane of chloroplasts and cyanobacteria , comprising one of the light reaction centers for photosynthesis 光系统( ps )是绿色植物光合膜上存在的两个光反应中心之一，具有利用太阳光的能量来裂解水、释放分子氧并还原质体醌的功能。
The results of changes in photochemical activity parameters and chloroplast pigments in the present study indicated that xanthophylls cycle was induced in leaves of boea hygrometrica when they were dehydrated for 8 days under very weak light condition ( 3u mol . m - 2 . s - 1 ) , xanthophylls cycle may play a photoprotective role in dehydrated boea leaves 为此本研究对牛耳草叶片光系统的光化学活性参数和叶黄素循环色素在脱水复苏过程中的变化进行了分析，结果表明，在极微弱的光强( 3 mol m ~ ( - 2 ) s ~ ( - 1 )下，脱水8天的牛耳草叶片诱导了叶黄素循环，叶黄素循环可能介导了牛耳草叶片脱水过程中的光保护作用。
