五层结构的高强度钢基改性聚甲醛复合材料的成型过程，是将改性聚甲醛加热熔化，经轧制，使熔融的聚甲醛渗透到大颗粒球形铜粉与螺旋铜钉的间隙中，解决了三层材料复合过程中，熔融的聚甲醛水平流动性远强过垂直方向的渗透性，造成了结合强度低的缺陷，使聚甲醛层与铜粉、螺旋铜钉及基体结合更牢固，提高了其承载和抗剪切的能力。

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.
