有限长度 meaning in English
finite length
Examples
- Timeout - mechanism for waiting for a given time period
超时? ?对一个有限长度的时间间隔的等待机制。 - One - dimensional chain model for finite length armchair carbon nanotubes
有限长度碳纳米管的一维链模型 - This paper derived the transfer matrix of the bilayer structure composed of left - handed and right - handed materials , and computed the density of states ( dos ) along the axis of the finite one - dimensional photonic crystal , which was constructed out of n such bilayer structures periodically
摘要推导出了由左右手材料构成的双层结构的转移矩阵，计算了由n个该双层结构周期性排列所形成的一维有限长度光子晶体沿其轴线方向的态密度。 - These methods are following : ( 1 ) in order to build fem model conveniently and enhance calculating speed , interceped a finite length and built a 2d - symmetry model . ( 2 ) in order to apply loads conveniently , kept the entrance of cold fluid . ( 3 ) in order to obtain numerical results in steady situation , lengthened export and import ends
这些方法主要有： ( 1 )为了便于建立模型并提高计算速度，对于实际工程中采用的长径比特别大的换热管采取截取有限长度的方法并建立二维对称简化模型； ( 2 )提出采取保留冷流体入口端，截取有限长度的方法施加载荷； ( 3 )适当延长翅片管的出口端和入口端，以便获得稳定工况的数值解。 - It is shown that if l is a modular lattice with finite length , and with 0 , 1 the least and the largest elements in l respectively , then 1 is the union of some minimal elements in l if and only if 0 is the intersection of some maximal elements in l , if and only if each non - zero element in l is the union of some minimal elements in l . by using these results , we give the necessary and sufficient conditions of an algebra module , module , ring , group and semigroup , respectively , to be semisimple
最后得出有限生成的ps -系是noetherian ( artinian )系的充要条件是它关于本质子系满足升链(降链)条件。第二章给出了一个模格是半单的若干充要条件。得到：有有限长度的模格l上，最大元1是若干极小元的并当且仅当最小元0是若干极大元的交，当且仅当l中任意非零元可表示为若干极小元的并。
