In a word, this paper designed the XK35-17 rotary control head to solve the problems existing in the using of the rotary control head homemade, such as excessively abrasion and lapse early. The loads caused by the aslant installing of the preventer system were calculated.

总之，本文完成了XK35-17型旋转控制头的研制，解决了现场旋转控制头旋转密封装置存在的早期过量磨损或早期损坏的问题，计算了由于防喷器系统安装偏心摘要引起的侧向力，为轴承的选用提供了理论依据。

Its theory is: evaluate periodical by various methods, and then make the results standardization, select the extreme value of these results as the final score of periodical. The research indicates that it is must been used carefully to calculate weight by combined assessing method; assessing methods based on order can't been used to combine; combined assessing based on extreme value method is propitious to establish harmonious relationship between assessor and assessee.

其原理是，首先选用各种可行的评价方法进行评价，然后将评价结果标准化，将同一期刊不同评价结果的极大值作为该期刊的最终评价结果，取得了较好的效果，研究表明，采用组合评价进行权重计算必须慎重使用；基于秩序的评价方法不能用于组合；基于极值法的组合评价方法有利于建立和谐的评价者与被评价者关系，结果容易得到公认。

Based on surveying the development of variable frequency power supply and analyzing its development tendency, and considering the practical features of the assignment, the conversion system is designed as follows: it selects the 3-phase Pulse Width Modulation Engine SA4828 as the PWM control signals generator; it chooses the single-chip-computer PIC16F877 as the microcontroller, which integrated the A/D modulation, which cuts down the complexity of the hardware system and strengthens the dependability of the system.

在论述和分析了变频电源及其控制技术发展的概况和趋势的基础上，结合本课题任务的实际要求，设计了一套中小功率的逆变电源。系统中PWM控制信号采用专用集成芯片SA4828生成，减轻了控制器的工作量也提高了系统的可靠性。控制器选用集成了A/D转换器的单片机，使得系统的硬件复杂性降低，提高了可靠性。

However, in human congenital system proteins associated with BSP in function have not been reported up to date.

此外，由于内含子序列的存在，因此扩增结果与引物设计的部位直接有关，选用3′UTR部位的引物为好。

This article introduces the selection of relative reactor value of filter X% and its relation to external performance of filter. The selection among parallel capacitor, dissonances filter and assonance filter based on the environment are discussed deeply. The relation between filter parameter and engineering design are once more discussed. Finally, how to coordinate the functions of harmonics and reactive power compensation is argued.

本文介绍了滤波器的相对电抗值X%的选择，以及X%和滤波器外部性能的关系，并深入讨论了如何根据不同场合分别选用并联电容器、失谐滤波器或调谐滤波器的问题，也再次讨论了滤波器参数和工程设计的关系，最后讨论了如何协调谐波和无功的补偿功能。

Aligned with cytochrome b sequences from 29 siluriforms in Japan, Korea, Russia, Africa, North America and South America retrieved from GenBank, and selected Astyanax mexicanus, Phenacogrammus interruptus, Cyprinus carpio and Oncorhynchus mykiss as outgroups, which are belonging to Characiformes, Cypriniformes and Salmoniformes, respectively.

所得序列与从GenBank下载的分布于非洲、北美洲和南美洲等地的鲇形目鱼类同一基因序列进行排序，并选用脂鲤目的墨西哥丽脂鲤、断线脂鲤，鲤形目的鲤以及鲑形目大麻哈鱼属的Oncorhynchus mykiss作外类群。
