migration rate

Secondly use similar material simulation study the big push degrees caving roadway sub-level caving migration regularity and thickness of coal seam and coal seam inclination and the relationship between stoping rate.

其次利用相似材料模拟实验研究了大推进度巷道放顶煤顶煤运移规律以及煤层厚度和煤层倾角与回采率之间的关系。

In credit risk models, the credit rating model and credit rate migration matrix are the basis of credit risk measurement; default and mark-to-market models are the major means; while credit derivatives models directly serve credit risk management.

信贷风险模型中，信用评级模型及信用等级转移矩阵是信贷风险度量的基础，违约和盯市等模型是信贷风险度量的主要方法，信用衍生工具等模型则直接为信贷风险管理经营服务。

Nomad families sometimes split the daily rental rate of$ 100 or more for a truck and driver for their migration.

在迁徙时，游牧民族家庭有时会合租一辆卡车和司机，分担每天至少100美元的费用。

We found that migration rate decreased as demes grew older.

我们发现：迁移率随着局域种群年龄的增加而减小。

Analysis of migration rate models for biogeography-based optimization

生物地理学优化算法的迁移率模型分析

At the same time, the experiments also showed that the foreground application throughput could improve 10%-40% by controlling the data migration rate.

同时，实验数据表明通过对数据迁移速率进行控制，可以提高10%-40%的前台应用吞吐量。

Tumor cell invasion and metastasis is the main reason for the high cancer mortality rate, and cell invasion and metastasis is based on cell migration.

肿瘤细胞的浸润和转移是癌症高致死率的主要原因，而细胞浸润和转移的基础是细胞迁移。

The results show that the dynamic process and partition equilibrium of migration are mainly determined by temperature. The higher the temperature, the faster the migration rate, the more of the migration and less time needed to reach equilibrium.

结果表明：温度决定了迁移的动力学过程及分配平衡，温度越高，迁移速率越快，到达平衡所需的时间越短，平衡时进入模拟物的抗氧剂迁移量越大。

This research made a deep study of the characteristics of thermal state in sintering process directing at the change of thickness distribution of each zone and migration rate, considering the result of mechanism model.

针对料层各带厚度的分布和迁移速度的变化，结合机理模型计算的结果，深入研究了烧结过程热状态特性。

The distribution of migration rate among demes in different ages is consistent under different mutation rates for migration and migration costs.

并且，迁移率在各年龄局域种群中的这种分布模式，在各种不同的迁移位点突变率及迁移代价下都是一致的。
