First,its characteristic of Gamma distribution can follow the bit rate of a VBR video source better.

该模型的Gamma分布特性能较好地描述VBR业务比特流的分布，由自相关函数决定的模型系数更充分地描述了自相关函数的行为，利用三态马尔科夫链的两个补充过程可以较理想地描述场景切换下的视频业务模型。

In this paper, the description method and style of hardware description language and its development environment MAXPLUSII are detailed.

本论文对硬件描述语言的描述方法和风格做了一定的探讨，介绍了硬件描述语言的开发环境MAXPLUSII。

These descriptions are brief, but based on them it is indeterminable and has disadvantage in system design and direct implementation. On the other hand, these works mostly focus on describing variants behaviors of Ambient calculus in one level, which makes it complicated to understand clearly how these variants behaviors work and how they work together. As a result, based on the unit ambient of Ambient calculus, a three-level semantics description framework is given for Ambient calculus.

这种描述方式尽管简洁，一方面却具有不确定性，不利于实际的网络计算系统的设计和直接实现；另一方面，这种语义描述方式均在一个层次上描述Ambient演算系统中的各种行为语义，使得Ambient演算中各种计算行为纠缠在一起，复杂而难以理解。

Base on the threshold voltage model presented, an intrinsic drain current model in strong inversion region is developed, which can describe the short-channel effects such as DIBL and charge-sharing effect well, and give special considerations for mobility, velocity saturation, channel length modulation and quantum effect. Based on the front interface surface potential model, a formula of unified inversion charge is derived, and an intrinsic drain current model in middle inversion region is developed.

利用所提出的深亚微米FD器件正、背界面表面势模型，建立了一个能够完整描述深亚微米FD器件本征亚阈漏电流特性的模型，能够准确地描述DIBL效应和背沟道漏电效应；利用所提出的阈值电压模型，建立了深亚微米全耗尽器件的本征强反型电流模型，很好地描述包括DIBL效应、电荷分配效应在内的小尺寸效应，对迁移率、速度饱和效应、沟道长度调制效应和量子效应进行了特别的考虑；利用所提出的深亚微米FD器件正界面表面势模型，推导了统一反型层电荷公式，建立了深亚微米FD器件的本征中反型漏电流模型。

In this paper, the propagation and focus properties for several modes describing hollow beam are analyzed, and the focus properties for hollow gaussian mode are particularly discussed. Furthermore, a new mode, high-order Bessel-Gauss mode, is put forward to describe hollow beams. The results for high order Bessel-Gauss beams propagating through lens focusing system and free space are derived by terms of Collins integral formula.

本文分析了几种描述空心光束数学模型的传输特性和聚焦特性，着重讨论了描述非中空光束的数学模型的聚焦特性；同时提出了一种描述完全中空的空心光束的新模型――高阶贝赛耳高斯模型，并且运用Collins积分公式，分析了这种新模型的空心光束的传输特性和聚焦特性。

It first describes some key formal description techniques including semi - FDT such as ASN. 1 and TTCN, and Estelle, LOTOS and SDL which have been standardized by ISO and CCITT.

文中论述了协议的典型形式描述技术，主要包括半形式描述技术：ASN.1和TTCN；标准形式描述技术：Estelle、LOTOS和SDL。

Lacking necessary metrization, RCC only describe spatial topological relations roughly without further accurateness, and it is also not easy to describe spatial relations such as distance, direction and so on, with the exclusion of topological relation.

但由于缺乏必要的度量，RCC只是粗略地描述空间拓扑关系而难以对其更准确地描述，也难以利用RCC描述除拓扑关系之外的其它空间关系，如距离、方向等。

Based on information theory and minimum description length principle, a novel parameter estimation and selection approach are presented.

靳奉祥等讨论了在保证模式描述的正确性和可靠性的前提下，信息损失与代价函数的和最小的描述是最佳描述sj。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
