This dissertation comprehensibly researches the performance of hybrid DS/FH spread spectrum communication systems, operating in a combined additive white gaussian noise , multiple access interference, and channel fading, particularly operating in hostile interference (partial band interference and multitone jamming). At the same time, the dissertation investigates performance of forward error correction coding and diversity technology against channel noise.

本文以此为背景，较为详细地研究了在信道中出现各种噪声干扰（高斯白噪声、多址干扰和信道衰落），特别是敌方的人为干扰（部分带宽噪声干扰和部分带宽多频干扰）时，混合DS/FH扩频通信系统的性能，以及前向纠错信道编码和分集技术对混合扩频通信系统信道出现噪声干扰时系统性能的改进情况。

The factors affect on the degree of substitution of product, yield and apparent viscosity, such as the mol rates of EPTAC with -NH2, reaction temperature, reaction time and the content of water in system have been discussed in detail. FTIR spectrometer and UV spectrometer are used to characterize the structure of the derivative and it is proved that substitution reaction mainly occurs on the -N element .The particle size and morphology of chitosan and quantemary ammonium salt of chitosan are analysised by comparing photos of their scanning electron microscope. The degree of substitution of HACC is determined by acid -base conductometric titration. An error in current formula of DS has pointed out and a correct formula has presented.On the base of experience of above experiment, the reaction conditions of HACC were systematically investigated through orthogonal design, and then the best conditions are found. Water-solubility and dependence of pH are studied.

壳聚糖和环氧丙基三甲基氯化铵在异相条件下发生反应，通过单因素实验，制备了一系列不同性能的壳聚糖季铵盐，本文首次详细讨论了反应条件(反应摩尔比、反应时间、反应温度、水含量)对产率及产物性能的影响；用红外光谱和核磁共振对结构进行表征分析时，发现季铵盐阳离子基以N位上取代为主；通过电镜图片对壳聚糖和季铵盐衍生物外观形貌进行对比，采用酸碱电导滴定法测定产物的取代度，并对常用取代度公式做了修正。

First, we concentrate on the analysis of conventional DS-CDMA and begin the discussion with convolutional coded systems.

首先，我们针对传统系统在经回旋码之通道编码后的检测结果进行理论上的分析。

Methods Faint the sufferer the adoption tuina the combination to 130 necks the Chinese herbal medicine take orally the treatment, the 10 ds are on curin g the timin g.

目的 观察应用内外兼治的方法治疗颈性眩晕的临床效果方法对130例颈性眩晕患者采用推拿结合中药口服治疗，10 d 疗程。

With solar loads regularly generating vehicle interior temperatures well in excess of 150 degrees, the DS vest disks delaminate themselves and fall to the bottom of the vest, effectively reducing the armor protection to nearly nothing. All panels shot after high temperature exposure failed in the first shot. This is unacceptable and is hardly a characteristic I would look for in a product to replace the current proven ESAPI in conjunction with the Enhanced Side Ballistic Inserts.

最后，也是最糟糕的，就是Dragon Skin在高温环境下的测试结果；现实中，一辆载员车辆很可能由于太阳的暴晒，内部温度达到华氏150度（摄氏66度）以上，而在这时Dragon Skin内部的陶瓷盘片则分层脱落，都滑落到防弹背心的下部，此时整个背心对人体要害部位的防护几乎为零；测试中几乎所有的护板在暴露于高温环境后出现首发击穿；这绝对是不可接受的。
