使转化

Its specific procedures are :first to treat the sample with hydrofluoric acid to convert the silica into a gas of silicon tetrafluoride to escape, and then at a PH value of 4 to 5 to treat the residual liquid with hydroxylamine hydrochloride to get the ferric ions reduced to ferrous ions.

其具体步骤为：首先用氢氟酸处理试样，使沉淀法白炭黑转化成四氟化硅气体逸出。

On the basis of the advantages of the previous distillation calculation algorithms, by eliminating the non—zero elements to the two sides of the tridiagonal band of elements in the component material balance equations by correlation of the draw rate from the main column to the sidestrippers and the return vapor stream from the sidestrippers to the main column, it changes these equations into a typical form of the tridiagonal matrix, and uses the simultaneous convergent strategy of the main column and the side strippers to speed the algorithm convergent rate.

在吸收前人蒸馏计算算法优点的基础上，通过求解主塔抽出到汽提塔的量和汽提塔返回主塔的蒸汽流之间的关联，以便消除组分物料平衡方程组系数阵中的三对角线两边的非零元素，使它转化为典型的三对角矩阵形式，而且使用主塔和汽提塔同时收敛策略，加快了算法收敛速度。

So it is available to avoid the calculation of trigonometric function during solving equations, therefore, reduce the time ofsolving and improve precision.

为此，本文提出三角函数数值等效转化的方法，使非线性方程中不含三角函数，在方程求解时，避免了三角函数的计算，因此，加快了方程的求解速度并提高了计算精度。

To understand whether the GST can protect plant from the damage of ultra-violet radiation,a UV inducible GST gene was isolated from an Arabidopsis cDNA library.The plant expression vector containing the GST cDNA was constructed and transferred into Arabidopsis thaliana plants by the Agrobacterium-mediated vacuum method.Molecular genetic analyses showed that the overexpression of the UV inducible GST could increase the tolerance of the transgenic plants to UV radiation

为了阐明GST在紫外辐射下是否对植物有保护作用，以紫外强烈诱导表达的GST cDNA为探针，筛选拟南芥cDNA文库，获得了这种GST的全长cDNA；利用此cDNA构建植物表达载体，并通过农杆菌介导法转化拟南芥，使其在拟南芥中得到大量表达；通过对转基因植株的紫外辐射耐性分析，证实了该GST的过量表达可明显增强拟南芥对紫外辐射损伤作用的耐受性。

For overcome nonlinear terms of any degree in the equation, we made a proper transformation according to the structure of the equation at first, make the equations into ordinary differential equation. Then solve the ordinary differential equation exactly, by auxiliary functions method and undetermined the coefficient method and algebraic computer system Mathematica.

为了克服方程中非线性项的任意次幂，我们采用的方法是首先根据方程的特点，做适当的变换，使原问题转化为常微分方程的问题，其次对该常微分方程再进行各类变换，如辅助函数法以及待定系数法……。

On elementary theory of non-thermal plasma, the mechanism of VOCs destruction was decided: under the action of activated particles (such as high-energy electrons, ozone, radicals, etc) produced by discharge reaction, a series of physical and chemical reaction will take place, the result is that harmful VOCs is decomposed into unharmful substance.

根据电晕放电等离子体的基本理论，得出了等离子体处理VOCs的机制：在放电产生的活性粒子(如高能电子、臭氧、自由基等)的作用下，发生一系列的物理化学反应，使有害的VOCs转化成无害的物质。
