通过对产形面曲率和包络切齿时产形面与齿曲面相对运动关系的分析，推导出双向圆弧齿轮齿面的诱导法曲率、诱导短程挠率和齿面的主曲率、主方向等计算公式。

Numerical simulation results show that the fluid flow in Lost Foam Process was different from that in an ordinary green sand mold, the molten metal flow forwards in a circular-arc shape from the ingate, meanwhile, the nature of the gating system influenced the filling process notably. As the polystyrene pattern decomposition has a strong quenching effect on the flowing metal fornt, a high temperature gradient was formed at the flowing metal front, this resulted in the dropping of temperature of the metal to the liquidus temperature quickly and decreased the flowability of molten metal, the temperature distribution in the metal behind, however, was even. The properties of the pattern and the coating affected the temperature distribution remarkably.

从内浇口开始，金属液呈放射状均匀向前充填，同时浇注系统性质显著影响金属液充型过程的流场；由于聚苯乙烯模样气化吸热对金属液的激冷作用，在金属液流端部区域产生很大的温度梯度，使得端部区域金属液很快降至液相线温度，降低了金属液的充型能力，而后续金属液中温度分布则比较均匀，模样性能、涂料性能显著影响这一温度分布特点。
