On any pre-printed clothing, the inventory cycle is a very important factor, it means you have to sell at a specified time out printed all clothing for the production of products in the future store.

对任何一款预印服装来说，库存周期都是一个非常重要的因素，它意味着你必须要在特定时间内卖出印好的所有服装，以便为以后生产的产品提供储存空间。

The cyclic symmetry algorithm can greatly save the computer memory and the CPU time without inducing any additional approximation. At last, the programs including pre-processing, calculation and post-processing are developed based on the models and methods mentioned above.

最后，在以上理论分析的基础上，本文编制了适用于循环对称结构的静应力与振动特性分析程序，以及适用于该程序的前后处理接口程序，并进行了算例验证，证明由循环对称算法得到的结果与整体算法、实验得到的结果完好吻合。

Moreover, they are not suitable for gears manufactured by different cutting tools. Based on gear generation principle, a new method to establish accurate 3D solid model of cylindrical gear by mechanism function of Pro/E is proposed. Taking the manufacture of spur-gear with pre-grinding hob as an example, this method is introduced in details and the accurate 3D solid model is set up.

以范成法加工齿轮的原理为理论基础，介绍在Pro/E平台下利用其机构模块的"轨迹曲线"功能精确构建各种刀具加工出来的渐开线圆柱齿轮齿廓曲线的方法，并以磨前滚刀加工直齿圆柱齿轮为例，详细介绍该方法的使用步骤，构建其精确的三维实体模型。

The results indicated, that the curves of hatching rate and normal diploid larva output showed a single peak, with the highest point at 3.4 τ0, corresponding to metaphase of the first mitotic division, the results were obtained irrespective of the different pre-treatment water temperatures, thus confirming the veracity of measuring heat-shock timing by τ0 and the wild applicability of this method in cyprinid and also suggesting a new way to the operations of induced gynogenesis in related fish.

结果提示了以τ0单位度量热休克处理时机的准确性以及该优化方法在鲤科鱼类雌核诱导操作中的通用性，从而为相关鱼类的雌核发育操作提供了有价值的资料。
