查询词典 predictive

Various classes of organic chemicals and diverse molecular structures often indicate complexity and multiplicity of toxic modes of action. Thus developing QSARs that are both mechanistically significant and highly predictive for diverse classes of chemicals that involved multiple or mixed mechanisms of toxic action will be advantageous and preferable.

In addition to providing short and occasionally intermediate-term pain relief, diagnostic blocks are considered predictive of the potential usefulness of subsequent neurolytic procedures such as radiofrequency denervation.

阻滞性诊断除了可以形成短暂或中期的疼痛缓解外，还可以预测后续的射频消融等神经切断术的疗效。

One is Bardina vorticity modification, and the other is Richardson number modification. Prediction results show that Bardina method has a superior capacity to Richardson number modification. Since DSM model has improved predictive results of the reversed velocity and tangential velocity, it is a potential method to predict strong swirling nonisotropic turbulent flow in stead of the longer convergence time.
