Starting with the traits of zero order impedance and the relationship between zero order current and zero order impedance,analyzes the main differences of electric traits of power cable s and aerial lines and the disadvantages of applying power cable s into the traditional grounded protection.

从正、负、零序阻抗特性以及零序阻抗与零序电流的关系入手，分析了架空线路与电力电缆电气特性的主要区别及传统接地保护应用于电力电缆线路所带来的弊端。

The reproductive development process of birch was described as follows: Male inflorescences extended from apical bud in early June. In later June, stamen primodium was differentiated in the bract of male inflorescence and the differentiation of bract was generated in female inflorescence. During July, anther layers and archesporial cell were differentiated in anther, then archesporial cell developed into mother microspore cell. Pistil primodium came into being at the same time. In early part of August the meiosis of mother microspore cell started. In later August, mono-nucleus microspore was formed. After September, both male inflorescence and female inflorescence were dormant.

白桦的生殖生长发育过程如下：6月初，雄花序从顶芽中生长出来。6月中下旬，雄花序苞片上分化出雄蕊原基，雌花序分化出苞片。7月，雄花花药分化出花药壁和孢原细胞，孢原细胞演化为小孢子母细胞，雌花序苞腋处分化出雌蕊原基；8月中上旬，小孢子母细胞减数分裂，8月下旬形成单核小孢子；9月后雄花序以单核小孢子状念越冬，雌花序以雌蕊原基状念越冬。

It is not constituted by endogamous groups, as is the Hindu Brahmanic hierarchy but by individuals and their families, for whom there is more possibility for mobility through and within interpersonal relations and through individual and intergenerational acquisition of civilisational achievements, military and civil.

这个级序与印度婆罗门阶序有所不同，组成这个阶序的不是同系种姓族群而是个体和他们的家族，对他们而言有更大空间通过人际关系来进行迁移，并且通过个体学习以及两代间的传承获得军事和民间的文明成就。

The main work of this thesis includes three aspects:(1) study the existing order adjustment methods and examine the characteristics of speeches, a new order adjustment method based on energy correlation is proposed. It is applied to JADE, KM, c-FastICA, and CMN to separate the convolutive mixtures from simulated and actual speeches, the results of analysis and comparison of separation performance verify the validity of the method.

针对卷积混合语音盲分离的频域算法，本文主要做了以下三方面工作：(1)研究了现有调序方法和语音信号的特性，提出了一种基于能量相关的调序方法，并应用JADE、KM、c-FastICA和CMN等四种复数BSS算法，对仿真和实际语音信号进行了盲分离，分析比较了分离性能，验证了本文调序方法的有效性。

It can be distinguished that the reservoir characteristic was controlled by diagenetic facies and diagenetic sequence.

阐述了在层序界面附近和层序体内部成岩作用发生的一般规律，认识到油气储层的储集性受成岩相和成岩层序控制。

For the different positions, forms and functions, we can distinguish between internal and external prefaces in the aspects of the structure, rhythm, person and endmost words.

内序与外序的位置不同、体态不同、功能也不同，区分内、外序的体态可从结构、音韵、人称与末端词几方面着手。

One is a hierarchy of endogamous status groups –castes - constituted by rules of propriety and a division of labour among castes, a hierarchy from the lowest to the highest, the most polluted to the purest, in which aspiration to rise in the hierarchy can be realised by caste, or sub-caste mobility, through domination converted into caste, or by acquiring higher caste accomplishment and changing or disguising one's natal status.

一个是族内婚姻群体阶序——种姓制度——各种姓间要遵循等级适当原则和劳动等级分工。该阶序从最底等级到最高等级，最污浊等级到最纯洁等级。在该阶序中，等级上升的愿望可以通过种姓或亚种姓的改变而实现。改变种姓或亚种姓的方法有通过正式的皈依进入种姓，或者取得较高种姓的成就，以及改变或隐瞒其天生的等级地位。

Based on the correlation of vast amount of drilling columns, log analysis, and mapping, this paper disscused the determination of the boundaries and internal building blocks of sequences. Finally, the sequence stratigaphic model of coal — bearing strata in epicontinental basin were established.

通过大量钻井剖面、测井资料对比和大、中、小型各类沉积断面网，以及主砂体骨格图等的编制，在含煤地层层序界面、层序内部各级建造块界面的确定，建立内陆表海含煤层序模式方面进行了探索，取得了重要进展。

In this paper, we mainly study extensions of partial order and finitely totally order for partially ordered semirings, and obtain some new results.

本文主要研究了偏序半环的偏序扩张和有限全序扩张，并得到了一些新的结果。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
