This thesis consists of four parts with six chapters.Part one is to study two classes of special matrices: nonsingular H-matrices and generalized H-matrices.

全文共六章，分四个部分：第一部分研究了两类特殊矩阵：非奇H-矩阵和广义H-矩阵。

For the characteristic of ring permanent magnet torque motor used in direct drive numerical control round table suffering from the effect of load disturbances and parameter variations, the H∞ controller design methodology without the orthogonality assumptions is combined with m-K iteration in m synthesis to design a m-H∞ speed controller in this paper.

针对直接驱动数控转台用环形永磁力矩电机易受负载扰动及参数变化影响的特点，将去除正交性假设的H∞控制器设计方法与m综合中的m-K迭代法相结合，设计了一个m-H∞速度控制器。

If for any two t-edge sequences whose initial edges have non-empty intersection, there exists an automorphism of H mapping one to the other, then H is called locally weakly t-transitive.

若对於任二个 t-线序列，其第一个元素的交集并非空集合时，均存在一个 H 的自同构函数将其中一个对应到另外一个，则 H 称为局部弱 t-递移。

Based on the fact that the h〓 and h〓 of a 2-band PR-QMF and their evenshifted versions make an orthonormal basis in L〓, a class of N×N matrices were constructed.

利用两子带PR-QMF的h〓和h〓及其偶数平移构成L〓上的基函数这一事实，构造了一类N×N的正交矩阵。

This paper use H.264/AVC video transmission, which defines a set of three Profiles. Applications of the Baseline Profile include video telephony, video conferencing; applications of the Main Profile include television broadcasting and video storage; and the Extended Profile may be particularly useful for streaming media applications. H.264 proposes the idea of Network Abstraction Layer. The output of the encoding process of VCL data will be packeted into NAL units. The NAL will give the NAL units corresponding header information according the contents of the units.

而本论文在采用的多媒体压缩技术－H.264/AVC，其定义了三种不同的Profile：Baseline Profile著重在视讯电话，视讯会议等偏重即时传输等服务类别，Main Profile重点则是电视的播放以及影像储存的应用，而Extension Profile则是在串流媒体的播放上提供了较多的技术支援。H.264/AVC并且率先提出了网路提取层的概念，影像在视讯编码层完成编码之后，移交到网路提取层中，而网路提取层会依视讯编码层产生的编码内容将其封装近NAL units，并给予应有的标头资讯。

Furthermore, the time of gut begins functional （29 ± 12） h in enterally nutritional patients was shorter than in parenterally nutritional patients （38 ± 14 ） h.

肠内营养组患者胃肠功能恢复时间（29 12）h较肠外营养组（38 14）h短，营养支持的日均费用（235 46）元较肠外营养组（344 65）元低，差异有统计学意义（P〈0.05）。

Effect of dehydration procedure Beads of Pavlova viridis were desiccated with four different procedures.Two dehydration rates were used, which are 0.9% water content/h and 10% water content/h.Resul-ts showed that slow dehydration is the best.

脱水程序的影响以绿色巴夫藻为研究对象，选择0.9%含水量/h和10%含水量/h两种脱水速度，分两步脱水，先脱水至70%含水量再脱水至最佳含水量。

The realization of this algorithm has led to a fact that the video conferencing system has better hearing perceptibility than those available oversea H.232 products, such as Netmeeting, based on the same H.323 specification.

算法的实现使得在多点情况下，此H.323视频会议系统比现有国外同类H.323产品(如Netmeeting等)具有更好的语音听觉效果。

Methods The rat models of ARF were made with mercury perchloride by intraperitoneal injection.Five minutes later,the rats in nmhaFGF group and model group were respectively injected with 40 μg·kg-1 nmhaFGF and normal saline by lingual vein.The rats in control group were injected with normal saline.At the time of 30 min,90 min,24 h and 48 h,the contents of blood urea nitrogen,creatinine and urine protein were detected respectively.

腹腔注射氯化汞复制大鼠急性肾功能衰竭模型，5 min后，nmhaFGF组经舌静脉注射nmhaFGF 40 μg·kg-1，模型组经舌静脉注射等剂量的生理盐水，对照组大鼠麻醉后注射生理盐水，在30 min、90 min、24 h、48 h取血检测大鼠血液中尿素氮、肌酐和尿液中蛋白含量的变化。

No IL-6 levels were detectable at Day 0 in perilymph.The earliest perilymph IL-6 levels were observed after 6 h,peaking at 24 h, and then decreasing gradually.

结果：在发生继发性内耳反应初始，外淋巴液未检测到IL-6，而6 h后外淋巴液中检测到了IL-6的最早水平，24 h后IL-6水平达到最高峰。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
