These methods are mainly divided into two classes. One is based on the separableness between primary and multiple or other differences, including periodicity of multiple, time difference and so on.

壓制多次波的方法主要分為兩大類：一類是基于有效波和多次波之間的可分離性和其他差異性(如多次波周期性五月天丁香六月激情综合在线、時差差異等)來預(yù)測與壓制多次波一到本高清欧美在线视频。

The non-uniform algebraic codebook is determined by the non-uniform statistical properties of the algebraic codebook, and the part-searching-area is determined by the periodicity of the algebraic codebook excitation vector, which makes up the insufficient numbers of signed pulses in algebraic codebook at low bit rate.

非均勻代數(shù)碼書由代數(shù)碼書的脈沖非均勻統(tǒng)計特性確定，部分搜索域代數(shù)碼書則由代數(shù)碼書矢量的周期性確定人妻无码伊人，該方法有效地彌補了低比特率情況下代數(shù)碼書中脈沖數(shù)不足的缺點狼友网页入口。

The bulk of solid-state physics theory and research is focused on crystals , largely because the periodicity of atoms in a crystal — its defining characteristic —facilitates mathematical modeling, and also because crystalline materials often have electrical , magnetic , optical , or mechanical properties that can be exploited for engineering purposes.

固體的內(nèi)部結(jié)構(gòu)和運動形式很復(fù)雜，這方面的研究是從晶體開始的一类黄片儿，因為晶體的內(nèi)部結(jié)構(gòu)簡單2018日日干得得啪，而且具有明顯的規(guī)律性，較易研究国内一级婬片A片免费看。以后進(jìn)一步研究一切處于凝聚狀態(tài)的物體的內(nèi)部結(jié)構(gòu)国产a自拍、內(nèi)部運動以及它們和宏觀物理性質(zhì)的關(guān)系。這類研究統(tǒng)稱為凝聚態(tài)物理學(xué)还能看的黄色网站。

Since Bloch's Theorem applies only to periodic potentials, and since unceasing random movements of atoms in a crystal disrupt periodicity, Bloch's Theorem is only an approximation, but it has proven to be a tremendously valuable approximation, without which most solid-state physics analysis would be intractable.

由于布洛赫定理僅對周期性勢場的情況嚴(yán)格成立久久精品欧美1024，而由于實際的晶體中不可避免的有各種缺陷或者原子相對于平衡位置的位移，所以布洛赫定理對于實際晶體來說只是一個近似(涩涩视频)色黄。但是布洛赫定理對于固體物理的研究不可或缺国产13一14娇小性。
