有效部分

The method of modeling and parametric estimation is an efficient technique for obtaining chemical information on material systems.It is one of the branches of the new frontier science—chemometrics.

模型建立和参数估计方法是获得物质系统化学信息的一种有效技术；是兴新的边缘学科——化学计量学研究的一个重要部分。

Arsenic trioxide As(2O(3), an effective drug for the treatment of acute promyelocytic leukemia, can induce apoptosis and partial differentiation in APL cells in vitro and in vivo.

三氧化二砷（As2O3）是治疗急性早幼粒细胞性白血病的有效药物。体内与体外的研究均显示它可诱导APL细胞凋亡与部分分化。

It is possible to use this form with function objects that define result_type , but only on compilers that support partial specialization and partial ordering.

如果要将这种形式用于函数对象，则该函数对象必须包含一个 result_type 类型定义，但是仅在支持模板部分特化的编译器中才有效。

It is possible to use this form with function objects that define result_type , but only on compilers that support partial specialization and partial ordering. in particular, msvc up to version 7.0 does not support this syntax for function objects.

如果要将这种形式用于函数对象，则该函数对象必须包含一个 result_type 类型定义，但是仅在支持模板部分特化的编译器中才有效。msvc直到7.0版（vc.net 2002）不支持这种方式。

The effect of partial substitution of alloy components on the electrochemical properties was also investigated.

结果显示，用少量的铁、铜和铬部分取代贮氢合金La5中的钴对改善贮氢合金电化学循环稳定性有效。

This is the condition that causes the virus to activate or drop its destructive payload.

However, he has not taken possession of the realty, and his interest does not go to the personalty which has already been contracted validly to A.

然而，他并未占有该不动产，而且他的权益还未曾触及到萨姆与A订立有效合同的那部分动产。

Furthermore,enzymatic production of cephalexin using free penicillin G acylase in aqueous system wasstudied. The parameters, including pH, temperature, concentration of 7-ADCA and molar ratiosof 7-ADCA to phenylglycine methyl ester, that affect the yield of cephalexin, wereevaluated. In section Ⅱ, the integration technique of bioseparation and biosynthesis was investigatedfirst time in the enzymatic production of cephalexin.

第Ⅰ部分主要建立了对酶法合成头孢氨苄过程行之有效的HPLC检测方法，实现了头孢氨苄合成过程中所涉及的四种物质，即头孢氨苄、苯甘氨酸甲酯、苯甘氨酸及7-ADCA快速有效的检测；同时对水相体系中头孢氨苄合成过程的影响因素进行了研究，明确了水相体系中温度、pH值，底物浓度以及底物配比对酶法合成头孢氨苄得率的影响。

The interval sowing experiments showed that 291S was a photo-thermo-sensitive male sterile line, which showed part fertile under short-day and low-temperature conditions when autumn sowing, showed high sterile under long-day and high-temperature conditions when spring sowing. The self-multiplication ability and sterility of 291S can be improved through selection effectively. The pistillody of stamens of 291S could be induced under certain photoperiod and temperature condition.

分期播种试验表明，291S是一种光温敏雄性不育系，秋播短日低温条件下表现为部分可育，春播长日高温条件下表现为高度不育，其可繁性和不育性经选择可以得到有效改良。291S在一定的光温条件诱导下会出现雄蕊心皮化现象。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
