These results indicated that HA and PmmA are both good bone graft substitutes for mastoid obliteration causing no structural or functional damage to inner ear and inducing no rejection or inflammatory reaction. PmmA, in particular, can be prepared as the occasion requires and can be solidified in a short time, making itself endurable and mouldable.

内耳连续切片，HE染色，光镜观察：实验耳耳蜗结构，形态正常，毛细胞排列整齐，〓泡内壁对HA和PmmA未呈现任何炎性细胞和巨噬细胞等，表明人造骨对内耳结构和功能无损害，不引起排斥或炎症反应，相容性好，是良好的骨组织代替材料，尤其是骨水泥可临时配制，能在短时间内象水泥一样凝固，具有一定的抗压性及成形性，是一种良好的乳突重建材料。

With the development of mullers and technology in the world in the past ten years,some cement factorys and cement machine shops having used and mended diversified mullers one after the other .

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。

Through the analysis of working principle and application of 1220 MAXI-PAV slipform paver ,this paper summarizes the adjustment methods of structural parameters for slipform paver to improve the cement concrete pavement.
