该方法不仅简化了具有多重强峰时匀场最优化过程，而且能够扩展到包括非轴向的三维自动匀场。
This method proposed herein greatly simplifies the shim optimization and is readily to be extended to three dimensions to include off- axis shimming.
发现高于二次硬比峰温度回火时，此钢的疲劳裂纹扩展阻力随回火温度升高而增加。
It is found that the steel resistances to fatigue crack growth increase with the rising of the tempering temperature when it is higher than the second hardening peak temperature.
