纲

A taxon or assemblage of taxa; e.g. the taxonomic group Insecta consists of all insects and the taxa in which they are classified.

一个分类单元或一组分类单元；例如昆虫纲这个分类群包含全部昆虫以及被列入的各个分类单元。

Insect:Any of numerous usually small arthropod animals of the class Insecta, having an adult stage characterized by three pairs of legs and a body segmented into head, thorax, and abdomen and usually having two pairs of wings.

According to this model, the dimensionless velocity potential of the incident acoustic field,(where, F is the velocity potential, v 0 the velocity amplitude of the vibration source, k =2 p / l the wave number), can be expressed as an integral equation over the surface of the levitator emitter and reflector, and then solved by the boundary element method.

该模型将入射声场速度势 F 的无量纲形式，（ v 0是声源振动速度峰值， k =2 p / l 是波数），表达为发射端和反射端表面上的边界积分方程，并通过边界元方法求解。

It researches on the approach to achieve continuous connections of container multimodal transport logistics system. Based on the idea of continuous connections the paper discusses the container transport choosing route problem. It combines the appropriate adimensionalize method in the appraisement method and mathematic model and resolves the problem that the unit of time and cost disunite and sets up the time-cost transportation route optimizing model which is an innovation on the basis of previous studies and gives an example to validate the model using the LINDO software.
