This work using negative bias to improve the nucleus density , and quartz glass was used as a kind of depositional substrate and diamond was deposited upon it in an mpcvd equipment . the diamond coating was characterized by xrd sem rama xps . the experimental results show that the mostly component of the film is diamond , and the results show that the sic is exist . it show that the diamond film not grow directly on the quartz glass , there exist the sic transition layer 在mpcvd制备得到了金刚石薄膜之后，分别用x衍射( xrd ) 、扫描电镜( sem ) 、拉曼谱( raman )和光电子能谱( xps )等测试手段对金刚石薄膜进行了表征，结果表明了生长出来的薄膜的主要成分是金刚石，同时发现了sic的存在，这表明了用mpcvd在石英玻璃上生长金刚石薄膜时，不是直接生长在sio _ 2上，而是有一个过渡层sic ，然后在过渡层上再生长一层金刚石薄膜。

By the design of microwave electric field mode and microwave mode converter ( mmc ) , the thesis participated in equipping an domestic microwave plasma chemical vapor deposition ( mpcvd ) equipment with a quartz glass window and water - cooled stainless steel resonant chamber in 2450mhz / 5 kw , introduced the basic machineries and functions of the sub - systems , including microwave system , gas - route system , vacuum system , detecting system and safeguard system 论文通过微波场型和模式转换器的设计，参与建立了一套2 . 45ghz 5kw带有石英玻璃窗、水冷却不锈钢谐振腔的微波等离子体化学气相沉积( mpcvd )系统( mpcvd - 4型) 。论述了包括微波系统、气路系统、真空系统、检测系统和保障系统等结构的组成及基本功能。
In the laminar flow regime , a analytical mathematical model is obtained by analyzing the film flowing in the wavy wall tube . in the turbulent flow regime , mathematical model almost ca n ' t be obtained directly because the turbulent flow in wavy wall tube is very complex , the model is obtained by quoting some results which are theorized by other studiers . in the part of experimental study , the flow form in the wavy wall tube is observed by transparent quartz glass wavy wall tube apparatus , the evaporation experiments are carried out in a 3 meters steel wavy wall tube , using glucose as the medium , heat transfer is invested , the heat transfer correlations of wavy wall tube evaporator are obtained 数学模型的建立过程中，对于液膜层流流动，直接对波形管内的降落液膜进行理论分析，得出液膜层流流动下数学模型的解析式；对于液膜湍流流动，由于湍流流动的复杂性，再加上所采用的波形管对湍流流动的影响，直接对降落液膜进行理论分析建立数学模型是极其复杂的，通过采用以前一些研究者得到的理论分析与实验结果，并引入与波形管的形状特征参数有关的修正系数k ，建立液膜在湍流流动下的数学模型。
The important application of diamond film is using the windows materials coat . because the glass is easy to be stain , it is very disadvantage to grow high quality diamond film . influence the diamond film application , and like commonly , rubbing the quartz glass can not improve the nucleus density , so it is very hard to grow high quality diamond film , and the quartz glass contain too much oxygen , it is very disadvantage to diamond growth 金刚石薄膜的一个重要的应用就是作为窗口材料涂层，但是由于玻璃易于被污染，对于生长高质量的金刚石薄膜是不利的，影响了其应用，而且由于一般的研磨衬底方法对于石英玻璃的成核方法影响不大，更难以生长出高质量的金刚石薄膜，而且由于玻璃中含有较多量的氧元素，对于金刚石薄膜的生长是不利的，因此对于金刚石薄膜在一些领域中限制了其应用潜力。
Now , the most popular method which grow diamond film on quartz glass is using vaporize plate to grow transition layer to improve diamond film growth from contain carbon vapor source ( c60 or c70 et al ) in the nucleus time all over the world , so it is important to improve the nucleus density for diamond film grow on the quartz glass 现在国内外的制备方法是为了能够在石英玻璃上生长出金刚石薄膜来，一般都是用某些含碳元素( c _ ( 60 )或c _ ( 70 )等)在成核期间通过蒸镀的方法来形成一层过渡层来达到促进金刚石生长的目的，因此如何有效的增强形核密度对于金刚石薄膜在石英玻璃上生长是十分重要的。
These sensor prepared have been applied to analysis of different species . ( 1 ) carbazole is a promising pharmaceutical species . a novel optical sensor for determining doxycycline based on the fluorescence quenching of n - allylcarbazole immobilized on an quartz glass plate surface by covalent bonding has been described ( 2 )用荧光基团2 -氨基苯并噻唑与对烯丙氧基苯甲醛合成了一种新的schiff碱类化合物，研制成了一种schiff碱新颖光化学传感器，用于呋喃唑酮的测定。
