As a private mobile communication system, The digital trunkingmobile communication system was boomed in 1990's, and before this, the appliedprivate mobile communication systems in market are almost the analog systemwith analog voice and digital signalling. And there are no data referring to thesystem design and parameters chosen. It includes the wireless channel accessalgorithm of the mobile terminals, single base station capacity in large regional networks, link designing schemes between the switching control center and basestation as well as the study of the service quality for the multiple traffic. Theseindispensable parameters in design a digital trunking communication system arestudied in this dissertation and some instructive achievements can be got. To provethe correction of the theoretical study, the result was tested with the popularsystem of pan-European digital trunking communication system.

数字集群移动通信系统是九十年代中、后期兴起的专用移动通信系统的一种新体制，在此之前国际、国内市场使用的都是数字信令、模拟话音集群移动通信系统其涉及领域是模拟体制，对数字集群的系统设计的有关参数、方法等的选用及其性能表现并无成熟的文献可供参考，如移动终端的无线信道接入算法、大区组网单基站系统的容量、基站和交换控制中心间的链路设计和多业务种类的服务质量等都是数字集群基站子系统进行设计和开发必须解决的关键技术。

By the analysis of the factors producing the moral hazard and research on the characters of information asymmetry on the process of the venture capital investment, we can conclude the design approaches of the contact mechanisms, including strengthening the risk resistance of the venture capital, inspiriting the venture entrepreneur by income and the interference of the venture enterprises.

富于弹性和灵活的契约机制是投资契约设计的主要内容，对道德风险的发生起到了积极的防范和控制作用，而投资契约保护性条款的设计则对道德风险的发生起到了法律上的震慑作用，并可弥补风险投资家因道德风险的损失。这两方面构成了投资契约设计的主要内容。

The National Development and Reform Commission project "Research and Implementation on China Next Generation Internet QoS" aims at devising a controllable, manageable and operatable unified IP QoS system supporting IPv4/IPv6 networks.

Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission;the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB,but also adapt to the gas's characteristic involved with H2S,CO,and other poisonous components without supplied m...

通过选用耐油性好的橡胶隔振器减少固体传声，可降低噪声约2 dB；设置半封闭式机组隔声屏障可降低生产车间工作区域内的噪声达13 dB，并且适合瓦斯发电气源中含有H2S、CO等有毒有害气体的特点，不需增加强制通风措施；在生产车间四周墙壁和顶棚上敷设吸声体，最大可降低空间噪声8 dB；根据瓦斯发电机排烟噪声频谱特性设计的阻抗复合式消音器的消音量可以达到30 dB以上。

Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission; the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB, but also adapt to the gas's characteristic involved with H2S, CO, and other poisonous components without supplied mandatory ventilation; locating the noise absorbers on the walls and ceiling of workshop can reduce noise by 8 dB; the exhaust silencer's elimination volume can reach above 30 dB which is designed in accordance with the exhaust noise spectrum characteristic of gas-combustion generator. By the combination of these measures, the noise of the gas- combustion generator will be under effective control, so that the gas power plant's noise pollution problems can be resolved.
