Results The reference range of serum Cys C in healthy people was ≤1.02 mg/L in our laboratory. The correlation coefficient between Cr and Cys C was 0.734 6. The serum level of Cys C in patient with DM was higher than that in healthy people. The level of Cys C in 2.18-3.15 mg/L and ≥3.16 mg/L could be defined as the limits of azotemia and uremia.

Through the widly use of in-direction selected topic tacic, mainly develop the explore ability while making mistakes. According to investigation and study, it may help develop the self-thinking ability of the students and also the practise level, team work spirit, the sense of responsibility; Many faced and mutually worked evaluatation tactic is a negation for traditionnal evaluatation, it is good for the establish of newly relationship between teachers and students also students themselves, it may help the rising of students'study level and their self-confident, then the perfect of oneself. I hope this text will have some teahing reference for teachers, thus this text would have little help for the implementation of Chinese comprehensiveness studing.

In chapter three the performance and structure of components of oxygen probe were especially investigated. The Cr-Cr〓O〓 powder was overcome by treatments. The reason of occurrence of thermal peaks on the EMF curves was explained. A water glass based cement which high temperature insulation was around 10MΩ within 10 seconds at 1600℃ was developed for the use of oxygen probe. The effects of tip end thickness of ZrO〓 tube and amount of reference electrode on response time and thermal equilibrium in oxygen probe were investigated. The optimum tip end thickness of ZrO〓 tube and amount of reference electrode addition were determined. It is found that the heat transfer in oxygen galvanic cell is the rate limiting-step in the response process. The national oxygen probe WOS Ⅱ type was designed and manufactured. By three batches of industrial tests its specification reached the level of American Celox Ⅱ type oxygen probe.

在第三章中分别从参比电极、高温绝缘水泥、插接件等组元入手，着重分析了其性能和结构，开发出了适合于钢液定氧用的Cr-Cr〓O〓参比电极，解决了Cr-Cr〓O〓参比电极高温产生收缩问题，解释了电动势曲线产生峰值的原因；开发了适合于定氧测头使用的水玻璃基耐火水泥，其高温绝缘电阻在1600℃，10秒以内为10MΩ左右；同时对ZrO〓管头部厚度、参比电极量对响应时间的影响以及定氧测头中的热平衡进行了研究，得出了合适的ZrO〓管头部厚度和参比电极加入量，确定了氧浓差电池中的传热是响应过程的限速步骤；设计制造了国产WOSⅡ型定氧测头，进行了三次现场定氧测试，其技术指标达到了美国Celox型定氧测头的水平。

In certain range,the bioenrichment of the mealworm larvae to Zinc in reference to the dosage added in the fodder is accorded with cubic curve relation:Y=181.2517+20.9314X-0.4099X2+ 0.0025X3. And the enrichment ability of T. molitor larvae in reference to the weight is also accorded with the cubic model:Y=35.8325+61.4155X-10.2980X2+0.4434X3. The enrichment of the larvae to Zinc can get to a high level in 2 to 3 days. This is anadvantage to numerous rearing of the mealworm. But we do not find a good rearing way to enhance the rate of bioenrichment to Zinc. And the further research about this is anticipated.

第二部分：采用锌作为添加元素，考查黄粉虫对微量元素的富集规律，结果表明：(1)黄粉虫虫体锌含量在一定范围内随锌添加量增加而呈三次曲线关系，符合三次曲线方程：Y=181.2517+20.9314X-0.4099X~2+0.0025X~3；(2)黄粉虫幼虫对锌富集能力随虫体大小变化而变化，与虫大小亦呈三次曲线关系；Y=35.8325+61.4155X-10.2980X~2+0.4434X~3；(3)黄粉虫虫体锌含量随着锌饲料添加而迅速上升，可在短期2～3天内达到较高水平，对于以黄粉虫为材料进行富锌保健食品生产有很大优越性；(4)本试验并未找到一种较好的锌添加方法来提高锌富集量，这方面的研究有待继续。
