查询词典 asymmetric variety

The asymmetric coefficients of debris flows are quite different in different area: large asymmetric coefficients of debris flow with low resistance; small asymmetric coefficients of debris flow with high resistance. The asymmetric coefficients of debris flow could be used to classify resistance characteristics of debris flow accurately and the resistance law of viscous debris flows was got by asymmetric coefficients.

A it is predominantly derived from the initial variety or from a variety which itself was predominantly derived from the initial variety, while retaining the expression of essential characteristics that result from the genotype or combination of genotypes of the initial variety; an essentially derived variety may have been obtained by the selection of a natural or induced mutant or of a somaclonal variant, by the selection of a variant individual from plants of the initial variety, by backcrossing, by a transformation by genetic engineering, or by any other similar method

一个品种主要由原始品种演化而来，或主要由原始品种的实质性派生品种演化而来，同时保留了来自原始品种基因型或基因型组合的基本特征的表达；一个实质性派生品种可能通过选择自然变异或诱变或体细胞无性变异、原始品种植株的个体变异的选择、回交、基因工程的改造或任何其它类似方法而获得。

A systematic study of correlation between nose disturbances and evoluted behaviors of asymmetric vortices over slender body models has been conducted. The new flow phenomena have been revealed in which the two-cycle behavior of Cy vs.γ curve for asymmetric vortices flow is continuously changed into one-cycle behavior with increasing of disturbance strength on the model nose tip. This newly found flow phenomenon is important and it provides a physical flow base to the perturbation active control of forebody asymmetric vortices flow.
