中文摘要：

根据由 Hellman 和 Worner 的相应分析的谷物边界方程，这篇文章是从谷物边界方程的适用性看了处理在秒阶段粒子(SPP ) 和谷物边界(GB ) 之间的相互作用范围。另外，描述相互作用范围的新表情被导出，它在在 SPP 和 GB 之间的相互作用范围能仅仅是以前分析的品质上的理论解决这个问题。它被看给在 SPP 和 GB 之间的相互作用位置那，相互作用范围能是这表情的使用决定的份量上。

英文摘要：

On the basis of the grain boundary equation by HeUman and corresponding analysis of Worner, this article deals with the interaction range between the second-phase particle （SPP） and grain boundary （GB） as viewed from the applicability of grain boundary equation. Also, a new expression describing the interaction range has been derived, which solves the problem in theory that the interaction range between SPP and GB can only be qualitatively analyzed previously. It is shown that given the interaction position between SPP and GB, the interaction range can be quantitatively determined by use of this expression.
