通过分析影响黄土湿陷性变形的因素,对于湿陷变形因素的关联分析,可以看出土性指标对湿陷性的影响程度,孔隙比的影响比较突出,基本上可以认为是在土性指标对湿陷性的影响程度中最大的,其它指标会因土质含量、黄土的类型不同而影响各异。总之,本文应用灰色系统理论的关联分析法对应用广泛的工程实用模型变形计算方法做一些因素分析、进行反思,同时证明了弦线模量法计算沉降是值得大力推广的,弦线模量法计算沉降在将来的工程实践中必将带来更为可观的社会经济效益。

Therefore, it has the important scientific research value in studying the relationship between the changing of the parameters (including the temperature, the humidity, the grain radius and so on) and the electricity and radioactivity of the medium. Applied the count statistics and the numeral value analysis, the paper analyzes, concludes and contrasts the data sufficiently through the experimentation, and acquires the following results that the resistivity and the polarizability both have the negative relationship with the temperature variety of medium from 0℃ to 200 ℃. The parallactic poalarizability is consistent with the temperature variety in the plan as well as the section, but their trends are exactly opposite. Power supply voltage has no considerable influence to the resistivity and polarizability by using duality variance analysis, however, the detecting depth and the plan position influence them greatly. Different AB/2 interval that increases by degree does not influence variance and the average value of the resistivity and the polarizability remarkably. By using the least double multiplication, the relationship of temperature-time-the influence radius of the fire source is carried up by the mathematic drawing up. After discussing their correl ation, I educe the influence radius of the fire source and carry out the 'trend analysis and forecast to the spacial changing of the temperature and the parallactic polarizability in the end.

The studies was proceeded on the the supercritical CO2 extraction technique of rotenone from Tephrosia vogelii. The extraction influences of technology conditions were systematically groped, The research results were listed as follows:1 The analysis method applied in this paper has been proved to be suitable to technology research of the studies on the SC-CO: extraction technique of rotenone from Tephrosia vogelii. 3 indexes, extraction ratio of rotenone. extraction ratio of total compounds and rotenone content percent in total compounds weight, were carried out with HPLC quantitatively determination combined with the sample weight loss after extraction. With these 3 indexes. The extraction influences of technology conditions were evaluated by synthesis.
