Abstractthis article is for the purpose of acting according to English discipline the characteristic, analyzes in the middle school English teaching through the concrete instance to have the polarization origin and the preventing and controlling the teaching process, for prevented the polarization, the teacher first should analyze the reason which the student studies falls behind, acts appropriately to the situation, pours into own primary coverage includes: First, the split up phenomenon occurs essence, reason and characteristic; Second, teacher's emotion factor and student's interest raise to polarization influence; Third, prevents the polarization measure the them, the key analysis showing intelligence factor is not the polarization primary the same time, according to English program of instruction request, under the new education form, requests each teacher to follow close on the class to change the step, found the science effective educational model, carries on the education reform attempt

The jamming of spread spectrum communications system and technology of simulationSpread spectrum communications has many basic manners of implementation, this paper main introduces the direct sequence spread spectrum technology. The technology of digital signals’ modulation and demodulation, aiming at phase shift keying; analyzing the capacity of resistance to anti-jannning of direct se- quence spread spectrum system（DSSS） and the method of synchronization in direct sequence spread spectrum system;base on the DSSS of the matlab’ s simulation。A simulation system of direct sequence spread spectrum communication based on the token library of SystemVue was given for the purpose of theory validation and performance analys. The results showed the system had good performance to combat muhipath interference。By analyzing the channel characteristics of low-vohage networks, the standpoint is put forward that the frequency applied to power line communication is a kind of limited resources. In order to settle out the problems such as the reliability and the interference, the technology of Frequency Hopping Spread Spectrum （FHSS） communication is applied to power line, and the model of FHSS for power line is built up. Some key technologies are discussed, such as the methods of designing m-sequence and carrying out the Direct Digital Synthesis （DDS） and keeping in synchronism and so on, and the simulation model of FH over the power line is built up. The simulation experiment shows that the frequency hopping with the limited frequency band source gives a new way of improving the reliability of communication over the power this paper, First of all, The basic principle of Simulation Software of System View was given, then we made a point on the application of System View to teaching in the course of Spreading band communication, And one DS Spreading band system as an example was given, So we can actualize System View is very important for Spreading band communication Courses .Along with the widespread application of wireless communications, the wireless frequency channel becomes extremely crowded, frequency channel resource is in great demand, the disturbance is very serious. The wide frequency communication is of many merits, can overcome all these problems, and provide even higher security technique. This thesis introduces directly expanded spectrum technique based on the SCDMA system base band signal, focuses on the MATLAB simulation, which belongs to the spectrum spread and the is one of the key techniques for frequency-hopping （FH） communication on the requests of synchronization for a high-speed FH communication system,we achieved synchronization by using a method combined synchronizationhead with time of day（TOD）. Mainly the paper studies the structure of synchronization sequence, synchronization of hopping pattern, bit synchronization,and so performance of synchronization is analyzed and the simulation is completed by using Matlab performance of synchronization shows that the synchronization of FH communication system makes synchronization time short, capture probability high, false probability low.扩展频谱技术有多种基本实现方式，本文主要介绍的是直接序列扩频技术，特别针对二进制的PSK调制解调技术，直接序列扩频系统的抗干扰能力分析与直接序列扩频系统的同步方法，并进行了相关仿真分析.为了对扩频通信进行原理验证和性能分析,给出了一种基于SystemVue图符库的直序扩频通信仿真系统.仿真结果显示,该系统具有良好的抗多径干扰能力.从分析低压配电网信道特点入手,提出了电力线频率资源使用受限的观点.为了解决电力线通信可靠性和干扰性问题,将跳频技术应用于电力线通信,建立了电力线跳频通信系统模型;讨论了跳频通信的关键技术,包括m序列选择、直接频率合成器（DDS）设计和跳频同步方法,并建立了电力线通信环境下跳频通信仿真模型;仿真试验表明：电力线跳频通信利用有限的电力线带宽资源,较好地实现了一定信噪比下的可靠通信.对System View仿真软件作了简要介绍，详细论述了其在扩频通信课程中的应用．并以直接序列扩频原理为例说明了该仿真软件的应用.随着无线通信的广泛应用,无线频道变得非常拥挤,频道资源非常紧张,干扰繁多、严重。扩频通信技术有很多优点,可以克服这些问题,并且可以提供更高的保密技术。文章介绍TD-SCDMA系统下行信号基带部分直接扩谱技术,重点介绍了扩谱和解扩的MATLAB仿真实现.同步技术是跳频通信系统的关键技术之一。针对高速跳频通信系统中同步的要求，采用同步头与时间信息相结合的方法实现跳频同步。文章研究了同步序列格式、跳频图案同步、位同步等问题，分析了同步性能，使用Matlab6．5完成了仿真验证。同步性能分析结果表明该跳频通信系统的同步时间短、捕获概率高、虚警概率低........

Jetta cars in China had 19 years, with its economic and practical, inexpensive, appearance is moderate, motivation, especially good enough, accelerating performance by consumers. But the pen jetta cars (AHP model engine) in use will happen various fault. Introduces the jetta cars (AHP model engine) under several faults in the reason, in the analysis is proposed, based on the troubleshooting measures.
