The density is Granger of height and breast diameter, and the heightis Granger causality of the diameter too, but the diameter isn't the causality of the height when logging number equates 2. In the intercomparison of effects of the diameter, height and density each other, the effect of the height and density is far-reaching. The height and density should be paid more attention for maintaining its' effect on the diameter in forest management.

当滞后阶数为2时，密度是胸径、树高的Granger原因，树高是胸径的Granger原因，胸径不再是树高的Granger原因，说明胸径、树高、密度3个林分因子中，密度、树高的影响更深远，所以在森林培养时，一方面要更加注意林分密度，优化林木的营养空间，促进林木因子的全面生长，另一方面，也不能忽视对树高的培养，以维持树高对胸径的影响。

We obtain new lower bounds for the sum of degrees of simple and distinctirreducible factors of the polynomial f1 +···+ fn, where fi(1≤i≤n) are pairwise relatively prime polynomials of several variables with coefficients in C.

PIAS proteins play roles mainly through two mechanisms: acting as SUMO E3 ligases to promote modifications of some transcriptional factors and cofactors, especially sumoylation, and to regulate their transcriptional activation; acting as structural proteins to offer platforms for protein-protein interactions and to promote the abstraction and recruitment of other regulators in the cellular signal pathway complexes or gene transcriptional complexes, companied by the subnuclear location of target proteins.

PIAS蛋白的调控机制主要有两种：一种是通过其自身所具有的SUMO(small ubiquitin-related modifiers)E3连接酶活性，促进对一些转录因子、转录辅因子的化学修饰，尤其是SUMO化修饰，从而调控它们的转录活性；另一种是作为构架蛋白，为蛋白质之间的相互作用提供平台，促进细胞信号通路复合物或基因转录复合物中其它调节蛋白的去除和募集，并涉及到靶蛋白的亚核定位。

We find the most contributions of form factors come fromΨπ,K andΨB, but the contributions ofΨσfrom the pion and the kaon meson, the contribution ofΔfrom B meson are very small, and can be neglected in most of the calculations.

结果发现π、K介子波函数中的Ψπ，K，B介子波函数中的ΨB对形状因子的贡献最大，而π、K介子波函数中的Ψσ，B介子波函数中的Δ对形状因子的影响很小，可以忽略。

By applying these two tools,we mainly discuss the problems as follows:1 Perturbation identities for the generalized polar decomposition:By applying singular value decomposition, we study the perturbation bounds of the generalized polar decomposition under unitary invariant norms when A is perturbed by addition or multiplication,respectively and give our bounds in identities.2 A class of new unitary invariant metrics: This paper generalized a class of new unitarily invariant metrics and give the upper-bounds and lower-bounds by C-S decomposition.

利用这两个强有力的工具，本文主要讨论了如下问题：1 矩阵广义极分解的扰动等式：利用奇异值分解，本文分别讨论了加法扰动和乘法扰动下矩阵广义极分解在任意酉不变范数下的扰动界，并首次以恒等式的形式给出了酉极因子和半正定因子的扰动界。2 一类新的酉不变度量：本文推广了文[22] 中的结论，定义了一类新的酉不变度量。

Age as one of the internal factors can affect the value of venturous revenue through acting on the checking results of the external factors ( e . g ., predation pressure ), and thereby affect the optimal migrating strategies . therefore , the patterns for dvm vary with the change of the animal ' s age

作为内部状态因子的年龄，因对外部因子识别结果的影响而对风险收益值有较大的影响，从而影响桡足类垂直迁移的最佳策略，导致其迁移的形式随年龄的变化而变化，一般来说，年龄越大的动物垂直迁移的时间越早、幅度越大； 3

The paper outlines the general design method for the minimum beat systems, an discussion on the role of the staleness weighting factor in improving transient response performance of digital control systems and the method to introduce the staleness weighting factor alongwith examples applied in practical engineering systems.

本文概述了最少拍系统的一般设计方法，讨论了失效加因子改善数字控制系统瞬态响应性能的作用，以及引入失效加权因子的方法、并给出了它们在实际工程系统设计中应用的例子、对完善最少拍系统设计方法在工程上的应用具有一定的价值。

In order to improve the statistical accuracy, we proposed an adaptive model based on context and features of audio coding. Using our proposed model, the scalefactors of current frame are represented with the statistical distribution of the N preceding frames.

为了进一步挖掘自适应模型的潜能，针对音频编码的特点，我们提出了一种基于上下文的自适应模型，利用当前帧前面N帧已编码的比例因子的概率分布来对当前帧的比例因子进行编码。

Study and Preparation of chromium-rich Yeast by Microorganism Fermentation Modern science demonstrates that chromium is the necessary trace element in human body. The active part of chromium is that of Glucose Tolerance Factor. GTF consists of glutamine, glycine, nicotinic acid and chromium. GTF helps insulin and acceptor to combine, increases transportation of glucose, improves fats to convert into CO2 and fatty acids.

现代科学证明铬是人体内的必要的微量元素，人体内铬的活性成份是葡萄糖耐量因子的组分，酵母中的葡萄糖耐量因子由谷氨酰胺、甘氨酸、尼克酸和铬组成的，GTF有助于胰岛素与受体的结合，增加葡萄糖的运输，能促进脂肪组织糖酵解转换成CO2和脂肪酸。

So far, the cancerogenic mechanism of lung cancer is not well elucidated. Some growth factors and growth factor receptors have been identified to participate in cancerogenic processes, but the downstream pathways regulated by those growth factor receptors are uncleared.

目前已知的癌症发病机理多是生长因子和生长因子的表面受体发生异常所致，因此，进一步阐明受体下游的调控基因对于阐明癌症的发生机理和进一步设计药物靶位点都是十分有意义的。forkhead box P4(FoxP4)就是本文作者在利用生物信息学方法筛选人类心脏发育候选基因的过程中发现的一个人类新基因，目前发现三种转录本。
