Quantum communication is a fashionable field of physics and informatics at present.Starting with the theoretical basis of quautum communication,the author investigats the method of dealing with information and the process of carrying information for both sides of communication.The variety of quantum state of transfers particle and unitary transformation matrix of acceptant are calculated in theory by four Bell radix.The circuitry of quantum communication is provided,and the author obtains Bell radix and qu...

量子通信是目前物理学和信息学科研究的热门领域，文章从量子通信的物理基础出发，研究了通信双方对信息的处理方法和信息的传输过程，从理论上分别计算了在4个Bell基下传输实体的量子态的变化和接收者的幺正变换矩阵；给出了实现通信的量子线路，并以该线路为基础计算了Bell基及对应的幺正变换矩阵和量子门。

Now , one of the direction of Trunking System is the trunking system which is based in CDMA technology and lies in traditional PUBLIC Digital Cellular Communication.

现在，集群移动通信的一个重要发展方向是在目前的公众蜂窝移动通信系统中，使用 CDMA 技术实现集群通信。

Especially in military affairs, it is the vital part in military operations. Short-wave communication is attractive because only little power and proper expenditure is needed when it is used for long distance communication. For this valuable trait, many country have expanded the area of short-wave communication's research, thus there has become more and more new-model communication system.

短波通信之所以能吸引用户用它传递信息，最基本的原因是由于进行远距离通信时，仅需要不大的发射功率和适中的设备费用，这一宝贵的优点，使得世界各国近年来加紧了短波通信的研究，出现了各种新型的短波通信系统。

It is widely applied in many fields,such as fixed and wireless communication,satellite communication,digital television and broadcasting,optical fiber communication,and magnetic recorders,etc.

LDPC码是第四代移动通信的关键技术之一，在移动和固定无线通信、卫星通信、数字电视和广播、光纤通信以及磁盘存储等诸多领域得到了广泛的应用。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
