The control strategies about the velocity-tension transmission system and the temperature of dyeing liquor were presented.

在介绍卷染机控制原理的基础上，对系统的控制要求进行了分析，并确定了控制方案，搭建了基于可编程逻辑控制器的卷染机硬件控制平台，提出了卷染生产过程中速度张力传动控制策略和染液温度控制策略。

Secondly, by introducing the generators of the infinitesimal transformations of Jourdain, the Noether′s theorem for the above nonholonomic systems of variable mass in event space has been obtained, which is based upon the invariance of the differential variational principle under the infinitesimal transformations of group.

这一成果揭示了力学系统的守恒量和其内在的对称性的关系，极大地推动了力学、物理学的发展。在近20年来，国内外的许多学者相继对Noether定理做了多方面的推广，不但用Hamilton作用量而且用微分变分原理研究完整和非完整系统的守恒律。

At last,introducing"coupling matrix library"and utilizing Jourdain'svelocity principle and forward recursive formulation method,the theoryestablished in chapter two and three is successfully extended to couplingdynamical formulation modeling of complex flexible multibody system.

最后，在第二、三章的理论基础上，本文引入"耦合矩阵库"的概念，利用Jourdain速度变分原理和单向递推建模方法，成功地将该理论推广到了复杂柔性多体系统刚-柔耦合动力学程式化建模。

Apparently, the results is determined extremely by theoretical algorithm. In 147 zinc-finger-containing genes, 50nt identity sequences were extracted. The results hint that 15 genes may related to block evolution. we analyzed the phylogenetic map of these 15 genes by uncorrected distance, Jukes Cantor distance, Tamura distance, Tajima-Nei distance, Jin-Nei distance or Kimura distance correction, but we found no satisfied result according to the block exchange pattern mentioned before. Introducing Bootstrap test to assistant correction, an comparatively perfect map was drown by Neighbor Joining method.

以147个含锌指基因为模板，我们搜索了其中的50nt一致序列作为板块式进化的核心，获得15个相关基因，应用无校正距离、Jukes Cantor校正距离、Tamura校正距离、Tajima-Nei校正距离、Jin-Nei校正距离和Kimura校正距离等分析了他们之间的进化关系，结果与已知的板块交换模式吻合度较差，引入靴带检验对Jukes Cantor校正距离结果进行统计学校正，并重新用Neighbor Joining方法绘制进化图，结果可靠性大大提高。

The linear sweep method can be fooled by introducing garbage data immediately after an unconditional jump instruction.

通过在一条无条件跳转指令之后立即插入无用数据，能够欺骗线性扫描方法。

In more competitive markets, companies tend to innovate in good times and bad, explains Yuko Kawamoto of Waseda University, but in Japan it often takes a downturn to get companies and consumers to try new things. During Japan's "lost decade" in the 1990s some companies flourished by introducing high-quality products at low prices.

据早稻田大学的Yuko Kawamoto解释，在更具竞争性的市场中，公司倾向于在经济繁荣和衰退时进行创新，但在日本，常常是经济下行时才会使公司和消费者尝试新的东西。20世纪90年代在日本"失落的十年"期间，有些公司通过低价引入高端产品而繁荣兴旺。

Once again, I thank to master and also my student Too Kaye Shyang for introducing "Qigong" to me.

我再次感谢老师和我的学生涂凯祥介绍了"气功"给我。
