常规方法

The experiment data of paramecium from Gause was used to investigate the efficiency of the method. And the twelve nonlinear real examples from "Agricultural Experimental Statistics" written by Mo Huidong were used to compare the difference between results fit by the Excel and the linear transformation method, respectively. The result showed that the Excel fitting method is not only simple and efficient for the parameter estimation but can fit various complex nonlinear equations also.

采用Gause的4组草履虫数据，研究了用Excel的"规划求解"工具进行非线性方程拟合的有效性，并以莫惠栋的《农业试验统计》一书中的12个非线性方程实例，比较了用Excel拟合与用常规线性转换方法拟合的差异，结果表明：用Excel进行非线性方程的拟合不仅简单易行、获得更优的参数估计，而且可以拟合各种复杂的非线性方程。

The method is easily realized with small computation amount,and its absorption effect is better than conventional paraxial approximation absorption boundary condition.

Methods:A total of 200 parturient were randomly divided into control and test group 100 cases each.

方法］随机将200例产妇分为两组，对照组100例病人为剖宫产术后常规护理组，观察组100例应用O

It is exact, reliable, simple and pellucid for the method to be proved.

以凸轮反求为例，按照常规反求方法，一般是对原有凸轮进行坐标三维测量，然后根据所得到的数据构建凸轮的CAD模型，再进行加工仿制。

Use method:┢ of wait very hot Qun returns graceful Fu? to take diluent 1 bottle of handstand are pensile, groovy disinfection, insert infusion implement, shut switch A, asepsis injector join is noted - inspiratory connect is backward air of the infuse inside infusion bottle, after amounting to constant pressure, shut switch B.

使用方法：①固体药品的溶解：取稀释液1瓶倒立悬挂，常规消毒，插入输液器，关闭开关A，将无菌注射器连接注-吸气接头后向输液瓶内注入空气，达一定压力后，关闭开关B。

According to the experience gained in traditional penetrating tests, this thesis has produced a high-pressure clay permeameter and discussed the instruments testing principle, measuring method and derivation of the calculation formula in details. Meanwhile, plenty of testing research has been done by taking an example for the permeability coefficient measuring of plastic concrete and the influencing factors of tests to the permeability coefficient of plastic concrete measured by this instrument have been analyzed.

3本文根据常规渗透试验中积累的经验，自行研制了一种高压土工渗透仪，对该仪器试验原理、测定方法以及计算公式的推导进行了详细的探讨，并以塑性混凝土渗透系数的测定为例进行了试验研究，对使用该仪器测定塑性混凝土渗透系数时影响渗透系数的试验因素进行了分析。

The paper proposed a pattern plated by photoengraving, and stamped two kinds of UHMWPE surface with different diameter and distribution. The effect of surface texture to tribological performance of UHMWPE was studied by comparasion of sample with turning surface.

本文使用采用用照相制版电铸方法制作模板，压铸成型了两种不同直径和分布规律的UHMWPE试样表面，通过和常规车加工试样表面的对比试验，研究了人造表面织构对UHMWPE摩擦学性能的影响。

Background: Conventional systemic therapies and phototherapy for psoriasis are limited by safety concerns that may preclude long-term treatment with these agents.

背景：银屑病常规的系统和光化学治疗受安全性的限制，因此也使这两种方法的长期使用受限。

The usual method of testing concrete may test and destruct a phototype only once and can not define the position,scope of drawbacks of concrete.It also can not demonstrate the extent of structure damaged by the method.Nondestructive testing can abandon these shortcomings.So it is valued and applied in the engineering practice.

常规的混凝土检测采用破损检测，它只能对同一试件进行一次测试并损坏试件，而且无法检测出混凝土内部缺陷的位置与大小，也不能判断结构物遭受破坏的程度等，而无损检测方法可避免这些不足，因此在工程实际中日益得到重视和应用。

The proposed method is based on the cataly-tic action of Os on the oxidation of phthalin with hydrogen peroxide.

但是，常规动力学方法操作烦琐，条件不易准确控制，重现性和精密度较差，这些缺点限制了它的应用。
