Wireless calling system simplex transmit and receive at most two. According to the task and requirements of its work fell 30 ~ 40MHz frequency band, we choose to use 35MHz frequency as the main launch point. Part of the launch phase-locked loop frequency synthesizer using technology, MC145152 and MC12022 PLL chips to lock in the exact carrier frequency 35MHz, the output carrier to achieve the stability of 4 × 10-5, reaching the accuracy of 3 × 10-5 by BB910 Varactor chip voltage-controlled oscillator and integrated to achieve MC1648 FM carrier modulation; selection transistor amplifier at the end of class 2SC1970, to work in the C state to enlarge and improve the efficiency of the amplifier output power to meet the design requirements. Receive part of ultra-large-scale AM / FM stereo radio IC CXA1238S as the main body, sensitivity, image rejection, signal to noise ratio and other performance indicators to meet the design requirements; integrated audio power amplifier chip LM386, voltage up to 200 magnification. Using PT2262/2272 encoding / decoding the data transmission circuit as well as its choice of Taiwan; and audio input and data input can be automatically converted; AT89S52 control the entire system as a part of program design using C language compiler in the KEIL51 Programming; show that the use of 16 × 02 LCD. After testing, a full-featured machine, the performance indicators in line with the system requirements, waveform receiver stability, no obvious distortion.

The simplex wireless ringing system divides launches and receives two major parts. According to the duty and the request, its operating frequency falls in the 30~40MHz frequency band, we choose use 35MHz to take the master station transmitting frequency. the launch part uses the phase-lock concentric type frequency synthesizer technology, MC145152 and the MC12022 chip composition phase-locked loop, locks precisely the carrier frequency in 35MHz, the outgoing carrier stability achieves 4×10-5, the accuracy achieves 3×10-5, controls oscillator chip MC1648 by varactor BB910 and the integrated pressure to realize to the carrier frequency modulation modulation; The last stage power amplifier selects triode 2SC1970, causes its work in the third kind of enlargement condition, raised amplifier's efficiency, the output has achieved the design requirements. the receiving unit take ultra large-scale AM/FM stereo sound reception integration chip CXA1238S as the main body, the sensitivity, the mirror image suppresses, the signal-to-noise ratio and so on each performance index to achieve the design requirements; The audio power amplifier uses integrated chip LM386, the voltage amplification factor is 200 most greatly. Used the PT2262/2272 code/demoding circuit to realize functions and so on data transmission service as well as to Taiwan choice; The audio frequency input and the data feeds may the automaticswitching; AT89S52 takes overall system's control section, the programming uses the C language to program on the KEIL51 compiler realizes; The demonstration uses 16×02 the lattice liquid crystal display. After the test, the complete machine function is complete, each performance index meets the system requirement, the receive waveshape stabilization, distorts not obviously.

汉英文翻译在线翻译有以下几种：
1、Google翻译
Google翻译在界面上还是遵循了非常极简的谷歌风格，整体看起来和普通的翻译软件似乎也没有什么差别。但是Google翻译还是有一点特色功能的，比如“实景翻译”。但当阅读大段文章的时候，如果逐字逐句的翻译会非常的麻烦而且费时间。
2、有道翻译官
清爽风格，虽然和Google翻译的清爽不同，但是在一众的国产软件中却少有的没有多余的新闻类推送干扰也是难能可贵。选择一篇文章后可以将其拍下来进行全文的翻译，而且翻译出的内容更加符合阅读的习惯，也就是说将文章语境也考虑进了翻译范围之内，更加适合大段落的文章内容。
3、百度翻译
百度翻译在功能性方面体现在其拍照翻译，实物翻译、长句翻译、菜单翻译、单词翻译都囊括其中，及时出门旅游相信也可以很好地满足用户的翻译需求。

Former network use, has not realized the security of the network, networks before this are not popular, safe consciousness is not strong. As the network gets general use, can steal the materials directly through sending the bag, data in all data, have endangered the security personal secrets of the personal network seriously. With the development of network technology, the person's use a lot of the fire wall (data communication filter), thus ensure one's own online security.Fire wall even if a kind of filtration fills (be can be said the filter), it can let the useful and harmless thing pass this filter, all filtration lose what other things are endangered. In the world of the network, that will be filtered by the fire wall is that the communication which bears the weight of the communication data charter. All fire wall can speak two word at least: Or deny. Say directly that accepts or refuses. This text has introduced the wide application in the letter is shut (the rural bank now) of fire wall, have described data, data are chartered,etc. the interception of relevant information and pass. In information technology era, the danger of the network sweeps the whole world, for some big enterprises, vital part on it it says to be to be fatal,it so long as steal information, in hobbyhorse, viruses hostile, it is very difficult for some materials to be saved from damage. Specially to bank, the very heavy one is heavy. If the bank is invaded, then all information of the bank is revealed, endanger to the online security of the national bank seriously. So, the fire wall has become the important tool of information security.关键字Online security。 The letter is shut。Fire wall
