平坦性 meaning in Chinese
flatness
Examples
- Door leaves - general and local flatness - measurement method
门扇.普通和局部平坦性.测量方法 - Flatness of some cyclic acts
一类循环系的平坦性 - Work , good optical function , high dependable , low spoilage , good direction - sense , ware length evenness , good stability , used for every environment
附加损耗低方向性好波长平坦性好环境稳定性好，适用于各种恶劣环境多种封装形式可选 - 5 . in order to keep gain smooth , enhance output power and efficiency , and reduce reflect factor and attenuation , inner matching networks are needed
5 、采用内匹配网络技术,设置输入输出匹配网络,以保持增益和传输特性的平坦性,提高输出功率和效率,降低反射系数,减少损耗。 - In this thesis , we will discuss the homological dimension and homological properities of rings and modules which is one of the most impertinent parts in homological theory . in the first chapter , we investigate the relation of homological properities between ring r . [ [ x ] ] and ring r , we prove that a module m is an injective or a flat r - module , then it is an injective or a flat r [ [ x ] ] - module respectively , and if m is an injective or a flat r - module , then hom ( r [ [ x ] ] , m ) is an injective r [ [ x ) ] - module , r . [ [ x } ] m is a flat r { [ x ] } - module
在第一章中，我们主要研究了幂级数环r [ [ x ] ]与环r上的模的平坦性与内射性之间的关系。证明了当只是一个完全凝聚交换环时，如果m是一个内射或平坦r [ x ] -模，则m是一个内射或平坦r -模。如果m是一个平坦r -模，则r [ x ] _ rm是一个平坦r [ x ] -模。
