Starting with a discussion of the coradical filtration of pointedcoalgebras in the second chapter,we give a vector space comple-ment of Cn?

首先从pointed余代数的余根滤链的结构出发，本文第二章给出了余根滤链Cn？

In general quantum case the equal-time kinetic hierarchies for the energy moments of the covariant Wigner function were established.

在普遍量子情形下，建立了协变Wigner函数的能量矩的等时动力论链和链的截断方案，得到了与低阶矩相关的物理密度量的输运方程和约束方程，并且证明高阶矩都能通过低阶矩表示。

The crystallizability and solution properties of polyacrylate depressants and their depressive effects on two waxy oils were studied. It was found that the crystallizability of PA depended on the length of its side chain and molecular weight. Gel was observed in the concentrated solution, The temperature of gelation, which was a measure of the crystallizability of PA in solution, was higher for the PA itself with stronger crystallizability.

对聚丙烯酸长链酯的结晶能力和溶液性质及其对两种含蜡油的降凝效果进行了研究，发现PA的结晶能力取决于PA侧链长度和相对分子质量，而其在溶液中形成冻胶或沉淀的温度（反映PA在溶液中的结晶能力）与PA本体的结晶能力有关，而PA对含蜡油的降凝效果则与PA在油中的结晶能力有关。

But due to the commonstructure characteristic of the segmented copolymers, the ratio of 〓 is still aneffective parameter to predict the crystallizability of the two segments in limitedenvironment.

虽然这个确切的比值对聚醚酯多嵌段共聚物不具有普遍意义，但是由于聚醚酯多嵌段共聚物共同的结构特征，软硬链段之间的相对长度仍是一个反映两种链段结晶能力的一个很有用的参数。

Summarily, the crystallizability ofthe soft segments in poly(ether-ester)s seems to be mainly determined by their ownmolecular weight.

同时样品的组成不均一性使得当硬链段含量高到一定程度后，软链段熔点反而有所回升。

Such as tiffany rings, earring, necklace, neck chain, bracelet, bangle, cuff link, money clip, key ring, key chain, key buckle .

如凡尼戒指，耳环，项链，头颈链，手链，手镯，袖口环线，钱夹，钥匙圈，钥匙链，钥匙扣。

Soon enough, platinum was used to make sugar bowls and coffeepots - and the early 19th century saw the birth of platinum jewelry in the form of decorative chains, shirt studs, and cuff links.

很快，铂金被用于制造糖和咖啡壶碗-和19世纪初看到了铂金饰品的装饰链，衬衫钉形式的诞生，和链扣。

The improved voltage model of rotor flux is proposed in the paper. It eliminates the influence to actual system function in the voltage model of rotor flux for the proper drift problem and cumulative error of pure integral calculus tache.

提出了改进的电压型转子磁链估算模型，消除了电压型转子磁链估算模型中纯积分环节所固有的漂移问题和积累误差对实际系统性能的影响。

RNA interference represents a common biological phenomenon of double-stranded RNA mediated post-transcriptional gene silencing, which lies in altitude plants and animals. The mechanism of this process is described as that: the dsRNA in cells are cut into double-stranded small interfering RNA. By joining with an effector complex termed RISC (RNA-induced silencing complex), siRNA binds to the cellular RNA with homologous sequences, and contributes to the degradation of the corresponding mRNA, the inhibition of specific gene expression.

RNAi技术是双链RNA(double strand RNA，dsRNA)介导的序列特异性的转录后基因沉默，广泛存在于高等植物和动物中，其机制是细胞内的dsRNA被Dicer剪切成双链的小分子干涉RNA (small interfering RNA，siRNA)与RNA诱导的基因沉默复合物结合，降解与之互补的靶mRNA，特异性抑制靶基因表达。

As to cyclic codes over finite chain rings, we study their stucture and develop the Fourier Transform method to finite chain rings. The permutation groups of cyclic codes and their extended codes are investigated using their Mattson-Solomn polynomials.

对于有限链环上的循环码，我们研究了它们的结构，并把傅立叶变换的方法推广到有限链环，用循环码的Mattson-Solomn多项式对循环码及其扩展码的置换群进行了研究。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
