  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 。
  2. Xt - yb - 1 is a development of the new company and quartz sand mixed casting artificial marble ( genus said : quartz resin ) resin, the resin curing exothermic peak at the low shrinkage of small, high surface hardness of products, not radioactive

    1是我公司新開發的一種和石英沙混合澆鑄人造大理石（屬稱：石英樹脂）樹脂，該樹脂固化時放熱峰低、收縮率小，製品表面硬度較高，沒有放射性。
  3. Metal poured into a mold cavity during the casting process solidifies with the possibility of shrinkage, segregation or porosity, which can prevent an " as - poured " casting from being acceptable for severe applications

    在鑄造過程中，澆鑄到模腔內的金屬在凝固過程中可能會產生收縮、分離或氣孔，這些問題使得「澆鑄」鑄件無法被苛刻環境應用領域所接受。
  4. Abstract : based on equivalent liquid surface descending method ( elsdm ) and isolated melting zone method, a multi - hot - spot and simultaneous shrinkage - feeding method was established to predict the shrinkage cavities of steel casting during solidification simulation. the shrinkage in each hot spot can be simulated and fed dynamically and simultaneously by itself using this method. then two practical steel castings were analyzed by this method

    文摘:本文在等效液面收縮法和孤立域法基礎上建立了預測鑄鋼件縮孔的新方法? ?多熱節和即縮即補方法，該法實現了對模擬鑄件各熱節的內部動態瞬時補縮，並採用該方法對兩個實際鑄鋼件進行了縮孔分析。
  5.
