The law is any, initially chose the study law, has not really wantedto result in too many, only thought later will be able to strive formore rights for more people, thinks initially own really very weak, initially understood the law, thought the law was very sacred, verynoble, a very chaste thing, it was multi-purpose, continuously thoughteach people all was is fair and the equality in front of the lawNobody may control it When I start studies legal time, I discovered in the law front, thelaw actually is the ruler and rich man's tool, completes with it tolegal playing with, said to the common people: Only is crowd of livesin the legal edge person The common people have the different matternot to be able to do, one cannot file the lawsuit, another cannot fallill, if they have done They will have two results Is the body andmind is exhausted, loses everything, another kind is reaches end ofrope, finally chooses leaves this heartless world
法是什么，当初选择学习法律，真的没有想得太多，只想以后能为更多的人争取更多的权利，想一想当初自己真的很幼稚，当初理解法律，认为法律是一个很神圣的，很高尚，很纯洁的一个东西，它是万能的，一直认为在法律面前每个人都是公平和平等。没有任何人可以主宰它。当我开始学习法律的时候，我发现在法的面前，法律其实是统治者和有钱人的工具，用它来完成对法律的玩弄，对老百姓来说：只是一群生活在法律边缘的人。老百姓有两样事不能做，一是不能打官司，另一个是不能生病，如果他们做了。他们将有两个结果。一个是身心疲惫，人财两空，另一种就是走头无路，最后选择离开这无情的世界

Sets of optimal injecting angles were obtained from the testing of five injecting angles. The results from the experiment on cutting forces showed that cold air injecting exerts less influence on main cutting forces. The lubrication properties of cold air injection don`t behave in the conventional form of friction reducing, but decrease the wear of cutting tool by reducing the plasticity of work piece and tool as well as the enhancement of strength of metal materials and tool. By comparing research on the dry and cold air cutting, it is verified that the cold air decreases the surface plastic property of tool and the cutting temperature, so that the front and back face wears of tool are reduced, and the tool life has been prolonged. Cold air can reduce the surface plasticity of manufactured metals, and improve the chip breaking effects. In the experimental ranges of injecting temperature and pressure, there was no cold-brittle phenomena occurred in metal materials. The pressure of cold air and injecting angle have magnificent influence on chip breaking efficiencies.
因此冷风射流的润滑性不是通过传统意义上的减小摩擦的方式体现的，而是以降低工件材料与刀具的塑性和增大材料与刀具的强度而减少刀具磨损来体现的；通过冷风切削和干切削的对比研究，证实冷风降低了刀具的表面塑性和切削温度，从而减少前刀面和后刀面的磨损，增加刀具的寿命；冷风能降低材料塑性，改善材料断屑效果，影响切屑出流，实验范围冷风射流的温度和压力并未导致材料冷脆现象的发生，冷风压力和射流角度对断屑效果的影响很大，在实验基础上首次获得保证加工质量前提下合理的冷风参数；冷风射流能有效地抑制已加工表面的积屑瘤和鳞刺，降低工件表面的粗糙度，使切削质量得到提高。

The paper investigates both block-type pilot linear minimum mean square error algorithm and IEEE802.16 OFDM channel estimation analysis. Simulation results confirm the block-type pilot structure is more suitable for IEEE802.16 system. An optimal pilot setting algorithm, based on space frequency domain, is explored and the pilot chart is presented. The proposed algorithm finds its application in MIMO-OFDM. Simulation results show the algorithm presents a good approximation to the perfect channel state information curve, with about 2dB difference in SNR. The simulation results also demonstrate the algorithm achieves fairly high stability in the environment of fast fading, performance of the proposed algorithm is better that of pilot training channel estimation.3. Taking into account the characteristics of IEEE802.16 OFDM system, OFDM system simulation platform is constructed in Matlab, exploiting simulink as a tool. OFDM modulation and demodulation simulation system are configured on LabVIEW platform. All the system signal processing is simulated, including defining system parameters, designing modulation model, and verifying all the proposed algorithms under different environments, such as white Gaussian noise, multi-path fading, with or without guard interval etc. Bit error performance is evaluated. The research provides valid theoretical basis for practical OFDM system performance evaluation.4. Taking advantage of software radio, the paper designs a hardware platform with both 256-IFFT/FFT and 512-IFFT/FFT OFDM schemes co-existing in one platform. You can predetermine one from the two schemes to carry out almost the same model function with different system performance and parameter setting.5. Referring to IEEE802.16 standard, the paper proposes a design method for generating signals and frames suitable for laboratory investigations implemented in laboratory environment.6. Based on 6701evm digital evaluation card, combined with analogy front-end, the paper designs a DSP software model to deal with baseband signal processing. An overall OFDM scheme, with modulation and demodulation function, is accomplished.
