To explore the function of PDE in canine central nerve , gene expression of 18 PDE subtypes in different fractions of canine central nerve (cerebrum,cerebellum,myelencephalon and spinal cord) were detected by RT-PCR,and PDE activity was calculated by the content changes of cyclic nucleotides before and after the PDE reaction examined by high performance liquid chromatography.

为探明磷酸二酯酶(phosphodiesterase，PDE)在犬中枢神经活动中的作用，采用反转录聚合酶链反应检测18个PDE亚型在犬中枢神经不同部位中(大脑、小脑、延髓和脊髓各段)的表达分布，以高效液相色谱法检测环核苷酸在酶反应前后的含量变化，计算PDE活性。

In this paper,both Newton's interpolation polynomial and Thiele's interpolating continued fractions are incorporaled to yield a kind of bivatiate vector valued blending rational interpolants by means of the Samelson inverse.

在这方面的理论，无论是牛顿的插值多项式和Thiele插值连分式都是推出一种向量值混合有理插值方法的Samelson逆。

As we know,Newton's interpolation polynomial is based on divided differences which can be calculated recursively by the divided-difference scheme while Thiele's interpolating continued fractions are grared towards determining a rational function which can also be calculated recursively by so-called inverse differences.

大家都知道，牛顿的插值多项式是基于均差的，可以递归出均差，而Thiele插值连分式是一个有理插值，也可以递归地计算，即所谓的逆。

The CPP was separated into five fractions using fractional precipitations by solvent/nonsolvent technique. Densities for binary mixtures of five fractionated and unfractionated CPP which contains a mass fraction of 30 % chlorine with solvents were determined. At a fixed temperature, concentration and solvent, the densities for binary mixtures of fractionated and unfractionated CPP with solvents have the same value.

用沉淀分级方法对氯含量为30％的氯化聚丙烯进行分级，得到5种窄分子量的级分，测定了氯化聚丙烯的不同级分与不同溶剂组成的二元混合物溶液的密度，在溶剂一定、浓度一定、温度一定时，不同级分氯化聚丙烯溶液的密度是相同的，不受分子量及其分布的影响。
