提出了一次性查找出所有简单路由的算法.为查询子网管理系统（SNMS）管理域中任意两个插/分处处用器（ADM）网元之间所有路由上的空闲时隙,此路由算法一次性计算出从起点网元（NE）到终点NE的所有可用路由,经实践验证,存储量需求和计算时间较好.

为提高核桃壳仁混合物的分级效果，对现有核桃壳仁混合物分级设备进行三维实体建模，利用EDEM软件模拟核桃壳仁混合物的分级过程，以筛面上物料的运动速度、质量以及各等级颗粒在统计区域的数量为指标，以振幅、振动频率、振动方向角、筛面倾角为考察因素，对振动筛分级工艺进行优化。结果表明：在振动频率12 Hz、振幅5 mm、振动方向角45°、筛面倾角4°的工艺参数组合下，各等级核桃壳仁的透筛率最高，分级效果最好。In order to improve the grading effect of walnut shell and kernel mixture, the existing classification equipment of walnut shell and kernel mixture was modeled by 3D entity, and the grading process of the walnut shell and kernel mixture was simulated by EDEM. Based on the movement speed, mass of the material on the sieve surface and quantity of particles of each grade material in the statistical area as indicators, the grading process by vibrating screen was optimized with the amplitude, vibration frequency, vibrating direction angle and the sieve surface inclination as factors. The results showed that the screening rate of each grade of walnut shell and kernel was the highest and the grading effect was the best under the conditions of vibration frequency 12 Hz, amplitude 5 mm, vibrating direction angle 45°, and sieve surface inclination 4°.
