查询词典 test at random

The two methods had accurate results in forecasting Cricetulus barabansis, but not in Meriones unguiculatus. It was mainly because Meriones unguiculatus population was affected by environment factors at random, and the dynamic tendency was not obvious. It meant that the two time series methods were accurate for the populations which were little affected by environment factors at random.

两种方法对黑线仓鼠捕获率的预测都比较准确，对长爪沙鼠捕获率的预测结果不准确，主要是因为长爪沙鼠种群数量受周围环境因素的影响随机性较大，趋势不太明显，说明此两种时间序列分析方法适用于受随机因素的影响较小，去掉随机因素的影响后有较好的趋势变化的种群。

The third chapter talked about two different treatments of quantum decoherence in V〓 system. For one the decoherence factor is been expressed in the form of a random external field. And the mean density matrix is calculated to signal the decoherence by showing its nondiagonal elements to approach to zero. In another numerical work done by us, random interaction between system and environment is imposed to mimic the decoherence factor.
