There are many problems for the cassava industrialization which can be illustratedas follows. As to planting, yield is still under lower level, for the manufactory, their scaleis small, distribution is dispersed, research capacity is unsustained, surroundingprotecting should be pay more attention and the connection with the farmer is to befurther solidified. Found on the result of the investigation, the key point is underthorough discussion, namely management, such as win-win system between farmer andcompany, as well as the advice for the development of cassava industrialization.

农民种植木薯人均收入500多元，木薯加工企业年实现工业总产值近7亿元，每年上缴地方政府财政上千万元，木薯产业已经成为县域经济的支柱产业之一；同时木薯产业化还面临很多问题，即木薯种植单产相对较低；加工企业规模小且分散；企业产品研发能力后劲不足；加工工艺技术相对落后，环保压力大；木薯种植农民与加工企业的利益联结不够紧密等。

The cost of MRC technology is lower than that of single horizontal well. It can drill two or multibranch hole from one major bole and encounter the pay zones in different positions, which improves the drilling-in capability and effective area and increases the oil and gas production of individual well.

MRC技术除具有水平井的常规优势外，其成本比单个水平井低，它是在一个主井眼中钻出两个或多个分支井眼，从而钻遇多个不同空间位置的产层，增大储层钻穿几率和有效面积，进而提高单井油气产量。

Four important conclusions were drawn. First, the CMLE method is the most suitable pro-cedure for parameter estimation in 1-parameter model. Second, the test construction of TIPS guided by classical test theory will not be valid for obtaining reliable measures. Third, the systemmatic ICC presenting method presented the perfect item and ability latent traits for the results in CMLE findings. Fourth, the complicated analysis of reliability coefficient and likeli-hood parameters met the precise and accurate measures of latent traits in either integrated process skills or hypothesizing skills.

本研究四项主要结论如下：一是CMLE确为分析试题潜在结构的量化模式，本文之精心分析过程及分析技术本身即为重要的测验资料分析规范；二是TIPS全卷及试题与原始之评量目标对应关系并未如古典测验理论之分析结果；三是各试题之表徵曲线图示法，显示在同一难易度鉴别度下，CMLE估计法分析确实显现高、中、低能力群之试题及能力特质；四是由信度系数及概度参数分析精准地显示了全卷及形成假说技能之试题参数之潜在特质。
