In order to meet the design and optimization requirement of developing led light , an effective method that is befitting in this work should be found out . in this article , the traditional led ' s light distribution is obtained through carrying out simulation of led ' s optical encapsulated structure by means of monte carlo method but not geometry optics method Led封装光学结构采用mc方法模拟可以输出光分布点图、光照度分布三维图、光强分布（配光分布）图三种有用的光分布信息，也可以输出具体的统计光子数值。
There are a lot of work been done to the yield curve up to date , but the research can not keep up with the development of bond market . under such circumstances , this dissertation wants to do some researches focusing on the yield curve . first , the study observes the figures of yield curves of china bond during different periods and qualitatively analyzes how they have developed to such figures 研究思路:本研究首先定性考察了不同时期我国国债收益率曲线的形状和成因,接着通过综合以前的研究并结合收益率曲线的散点图对不同时期收益率曲线分别建模,利用模型定量研判市场利率走势,并对远期利率作出预测,最后根据实证研究结果对国债投资和管理提供了一些结论和建议。
This paper , based on the grain - size analysis and the comparative result of the mz - o scatter gram of ancient aeolian sands in milanggouwan section with the modern dunes in mu us desert , holds that fossil eolian dunes are a proxy of the dune activation , and be regarded as " desert process " , while the overlying fluvio - lacustrine and palaeosols on the dunes are regarded as inter - desert process 文中根据粒度分析及古今砂丘的mz ?散点图比较结果，认为古代风成砂丘特别是古流动砂丘是砂丘活化的体现，视为“沙漠期” ，而砂丘上覆的河湖相沉积与古土壤发育则可视为“间沙漠期” 。
Compound pattern ( 6 . 4 % ) , its scatter map of isi series displayed two or more oscillation patterns . 4 . after the bath in 1 . 8 - 3 u mol / l veratridine , touch or pressure on the l5 receptive fields could trigger some primary silent drg neurons to produce high - frequency firing , termed triggered oscillation , whose interspike intervals ( isi ) showed u - type or other types of oscillations 在部分静息神经元lsdrg浸浴壹芦碱后，触压该神经元的皮肤感受野，可以触发产生持续数秒至数十秒的高频放电，在散点图上，其isi序列形成u字形或弥散形等型式的振荡，称之为触发振荡。
Correspondingly , the hedge combination invention model has become hedge joined speculation mathematical model . the new model has been analysed theoretically and is effective in enterprise ' s active application . the thesis proves the linear correlativity of spot price and future price by excel software , calculates correlation of two markets . hedge rate . regress equation by two market price and offers quantitative evidences for investment decision - making 本论文运用excel软件，利用散点图证明了期、现两市场价格的相关关系，对现货价格、期货价格进行线性回归，给出了计算期、现两市场的相关系数、套保率的方法，为企业投资决策提供可量化的依据，在实际运作中，具有较强的可操作性。
Secondly , the study develops different mathematical models according to different periods by synthesizing previous research and observing the track of scatter plots of yield curves . thirdly , it quantitatively predicts the trend of interest rate and forward interest rate by these models . last but not the least , this study come to some conclusions and present some suggestions according to the empirical research 本研究首先定性考察了不同时期我国国债收益率曲线的形状和成因，接着通过综合以前的研究并结合收益率曲线的散点图对不同时期收益率曲线分别建模，利用模型定量研判市场利率走势，并对远期利率作出预测，最后根据实证研究结果对国债投资和国债管理提供了一些结论和建议。
Substation staffs have took care of the question that how to create switching sequences by computer . at present , the computer aided creating switching sequences system have problems such as unsatisfactory generalization , maintenance and , shortage of dealing with abnormal situation . according to the above shortcomings , this paper adopts the technology of expert system to design and realize a creating switching sequences automatically or through selecting device from wiring diagram while equipment is in normal or not 利用计算机开列操作票一直是变电站运行人员非常关心的问题，针对现有的计算机开票系统通用性差、维护困难、缺乏异常情况下开票等问题，本文采用专家系统技术，设计并实现了一个能在正常和变电站设备发生异常情况下进行点图和自动开列操作票的开票系统。
On the basis of examination of more than 2000 specimens ( including types ) from 15 herbaria worldwide , the characters features of species , phonological phase , ecoloigical habit and the relation to close species were analyzed , recorded and described , the disputed species were compared , measured and counted in detail , the quantitative analysis to different characters was done through dot - map , the variation pattern of major morphology characters was analyzed and their significance for a better delimitation of the species was evaluated 查阅或借阅国内外17个标本馆近2000份标本(包括模式标本) ，描述了每个种的性状特征、物候期、生态习性及其与近缘种的关系，确定性状的极性，对有争议种的形态性状进行详细的测量和比较，用散点图对个别性状作定量研究，分析了主要外部形态学性状的变异式样、变异幅度及其对划定物种范围的价值。
Based on the general design of bent structure . aiming at multi - complexion bent structure , the essay calculates the dynamic period and domino effect of earthquake , 66 groups in all about shearing force ( q ) and crooked ( m ) of control section . the essay chooses appropriate regress parameter through repeating attempt , and makes use of origin regress analysis program protract dot chart of multi - structure , through multinomial regress analyse , finally works out the simplified formulas for single - stride bent with different stride shearing force ( q ) and crooked road ( m ) of control section 以排架结构常规设计为基础，针对多种工况下的排架结构，计算了自振周期、地震作用及其效应，共有66组控制截面的剪力q和弯矩m 。然后经过反复尝试选定合适的回归参数，利用origin回归分析程序绘出各类结构的散点图，经过多项式回归分析，得到单跨排架不同跨度时控制截面剪力和弯矩的简化计算公式。
On the basis of the geochemistry digital model arithmetic of triangulated irregular network , i change the arithmetic of auto - tracing isoline . in process of auto - tracing isoline , the proplem of tracing - crossand and mini - heave was resolved . the isoline is smoothec by linear overlap algorithm . in addtion , the model can build other unit of map such as extramum point , polygon 在不规则三角网数字模型的基础上，改进并实现了等值线生成算法，解决了等值线生成中的分叉问题，解决了等值线上的小凸起问题；对等值线采用线性迭代算法进行了圆滑处理；提出延伸三角网算法，用于实现了开等值线的闭合；生成用于地学分析的区域图元，等值线图元，极值点图元等。
