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。
