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。

该模型考虑了裂纹尖端大转动和离散单元形状变化对应变能释放率计算的影响，修正了裂纹尖端应变能释放率的计算方法。

The results show a reversed-flow region is formed at the tip of the pressure side due to the influence of the outside hot combustion gas and the pressure side tip thickness. The pressure gradient makes the coolant flow exit from the trailing edge slot first separates from the trailing edge cut-back, and then affected by the expansion wave, the coolant gas reattaches the cut-back of the trailing edge after passing a certain distance.

研究表明，由于外流和叶片叶盆尾缘厚度的影响，叶盆尾缘端部形成局部回流，叶片尾缘劈缝气体流出后受压力梯度的影响先抬起与叶背面分离，在流过一段距离后由于跨音速流膨胀波的作用，冷气流再次附着在叶背尾缘上。
