容器通过事务边界和部署描述符表示了事务模型，并在运行时控制事务的提交和回滚。

The container infers the transaction model from the method boundaries and deployment descriptor, and controls the transaction commits and rollbacks at runtime.

闭路拓扑原理和欧拉公式是检验实体模型边界表示的拓扑与几何一致性的重要工具。

For inspecting topological and geometrical unanimity of a solid model, principle of closed path topology and Euler′s formula are important tools.

在细微边界元识别和细微特征分解交替进行的过程中，任意用边界表示法表示的几何模型可逐步简化到任意程度。

In the cycle of detailed boundary entities recognition and detail feature decomposition, an arbitrary solid model which is represented as B-Rep model can be simplified to any level.

然后定义分割片的特征边界和边界强度函数，用以表示各预分割区域边界上的形变模型；

Then we define the boundary strength function and the feature boundary of each patch, to construct a deformation contour on the patch's boundary.
