求翻译：与以往齿轮优化设计的方法不同，本文介绍一种基于ANSYS参数化设计语言(APDL) [8]的齿轮离散优化的设计方法对上述齿轮进行优化设计工作。是什么意思？

Optimal Design of gear with the previous method, this paper presents a parametric design language based on ANSYS (APDL) [8] for discrete optimization of gear design method to optimize the design of the gear work.

As in the previous gear optimization and design of this article describes a method based on different ANSYS parameterized design language (APDL) [ 8] the gear discrete optimization and design methods to optimize the above gear design work.

Optimizes the design with the former gear the method to be different, this article introduced one kind is separated the design method based on the ANSYS parametrization design language (APDL) [8] gear which optimizes to the above gear to carry on the optimized design work.

Gear optimization design methods are different from before, this article describes an approach based on ANSYS parametric design language (APDL) [8] discrete optimization design method of gear to the optimized gear design work.

Optimal Design of gear with the previous method, this paper presents a parametric design language based on ANSYS (APDL) [8] for discrete optimization of gear design method to optimize the design of the gear work.
