  1. The key to prediction of casting shrinkage / porosity lies in ascertaining the critical value of temperature gradient and niyama criterion. the thesis put forward two methods to ascertain the value, one is which is positive - direction and the other is negative - direction. we verify the realistic arithmetic of temperature gradient method and niyama criterion method by experiment, and we can draw a conclusion that the arithmetic is correct and reasonable in most cases and choice of developing tool is sound

    臨界梯度值和新山判據臨界值的確定是實現縮孔縮松預測的關鍵，本文提出了確定臨界值的正向法和反向法，並以高鉻鑄鐵件縮孔縮松預測和鑄造工藝改進為研究對象，應用正向法，確定了溫度梯度法的臨界值為180 m 。
