this paper analyses the basic principle of tpc,compares the error performance in the system which has been applied with tpc with the uncoded system,studies the influences which different block codes and iterative numbers to tpc decode performance.under the circumstances of different iteration numbers and block codes,experiment simulation is carried on.the simulation results indicate that introduction of tpc can get the code gain of 5~6 db.tpc decoding algorithm is simple,and doesn′t have the error floor,the complexity of its hardware implementation is smaller,it is a kind of practical channel coding method.

摘 要：在分析turbo 乘积码的基本编译码原理的基础上，比较了未编码与编码后系统的差错性能，研究了选取不同分量码、不同迭代次数对tpc译码性能的影响。在不同迭代次数与分量码情况下，进行了仿真实验。仿真实验表明，在相同的差错性能条件下，采用tpc码能带来5~6 db的编码增益。tpc译码算法简单，没有错误平层，硬件实现复杂度较小，是一种非常实用的信道编码方式。

The experiment results showed that, the MnO_2 particles scattered uniformally after milled for 6h, the average diameter was 300nm, which loaded on the surface of fiber in flat successfully. The removal efficiencies to HCHO of MnO_2 milled for 6h was up to 94.07% after 72h, the removal efficiencies increased with the content of MnO_2 loaded, its increased after treated with DMF, or so was 7%.

实验结果表明，研磨6h的MnO_2粉末分散均匀，平均粒径可达300nm，以平铺的形式均匀地负载于纤维上，效果比较理想；随着吸附时间的延长，研磨6h的MnO_2粉末反应72h对甲醛的去除率达94.07％；活性炭／腈氯纶负载MnO_2纤维对甲醛的去除率比未负载的明显提高；随着纳米MnO_2负载量的增大，甲醛的去除率变大，用DMF处理后的纤维对甲醛的去除率有所提高，大约提高7％。

A detection method for welding lines based on K-L algorithm is discussed. Infrared light source is applied to get high quality images of welding lines through CCD. Image template libraries for unwelded and welded lines are constructed and the welding line image is processed by K-L algorithm to match with the template libraries to judge if the welding line has been welded. The experiment shows that above method is effective with high precision and speed and it can be applied on real-time detection of welding lines.

Methods: Integrated and disrepaired skins in the rats were smeared with Salicylic AcidPhenol Liniment by the maximum tolerated dose only. The toxic reaction of the animals were observed and recorded continuously from the beginning of using the drug to 7 days, and evaluated by using the general standard of the reaction of skin stimulation in pharmacology. Animals were executed by taking off acanthi and blood was collected to check up the periphery blood routine and serum biochemistry at the end of the observation of the rats. And after the dissection, the pathological change of main visceras, such as heart, brain, liver and kidney were observed with naked eye and pathological slices. The data of this experiment was used to calculate the value of LD50 by using Bliss rule.
