We discussed the effect produced by risk function on deciding rule between twoparameter estimators, gave a probability rule for choosing estimator.
探讨了风险函数对评判参数估计优劣的影响，提出了衡量估计优劣的一个概率判定准则。

It is shown that the damping value established from three parameter model is smaller than that of twoparameter model or elastic semi-infinite body theory.
由该模型的分析结果表明，其阻尼值比之按两参数模型以及按弹性半空间体的理论模型求得的值要小得多。

This two-parameter CD command has lots of USES: swapping between similar directory paths where the only difference is a database instance name, a branch name, or maybe a date.
