应用Shannon率失真理论以及密度进化理论，阐述了最佳量化译码的时变特性，建立了离散密度进化的条件阈值概念，提出了二元输入对称信道上逼近最佳时变量化译码、进而接近连续译码的时不变量化译码设计方法，推导了量化和积算法与最小和算法的等价条件，从误码率性能、错误平层和平均迭代次数等三个指标全面衡量量化译码性能； 5。

Through the analysis of the increment, storage and configurative conditions in three industrial of agricultural and husbandry areas of Inner Mongolia,we calculate the participant factors'efficiency and construct economic model of the optimized configuration. The thesis points out that now the ratio of human resource of the optimized configuration factors in Inner Mongolia agricultural and husbandry is not at the best ratio point.

首先，从农牧区人力资源的增量、存量和在三次产业中的结构配置状况分析了内蒙古农牧区人力资源的现状；其次，利用线性回归的分析方法，对农牧区各投入要素对经济增长的贡献进行了测算，分析了影响农牧区人力资源配置效率的因素，并构建了农牧区人力资源优化配置计量模型，据此分析得到：内蒙古农牧区物质资本与人力资本投资比例位于最佳比例点附近，且大于最佳比例，需要通过增量调整来实现产出最大化。

To study the performance of photocatalystic reactor, we designed and made the experiment rig that is fit for sewage treatment. Considering practical applications, we have discussed the optimum inclination for flat photocatalystic reactor. Under the condition of lack solar radiation fact survey date founded on wave band, the suggestions to determine the optimum inclinations for flat solar collector are given. In the experiments of degradation of dye, Congo red and Methylene blue dyes were taken as targets' contamination.

在光催化反应器的研究中，我们在现有的基础上，自行设计制造了适合于草酸铁/过氧化氢体系污水处理的平板型光催化污水处理实验装置；考虑到今后的实际应用，还对其最佳倾角问题进行了讨论，在缺乏长期太阳分波段辐射实测数据的前提下，建议平板型光反应器采用平板太阳能集热器的最佳倾角。
