We commute the jacobian phase of the integral measure under the chiral rotation , we also discuss the fermion determent of the non - commutative chiral qcd2 model and provide the effective action of the non - commutative chiral qcd2 model 我们用fujikawa路径积分的方法研究了二维非对易空间的手征qcd _ 2模型作用量费米子部分在手征转动下所产生的手征反常。
Conclusions : the in - vitro method that partial double - strand dna with t7 wi l . - toi promoter sequence as template and synthesizing by t7 rna polymerase can product high yield , excellent purity shrna . lt is a convenient - , effective ^ low - cost method and fit for small rna synthesis and rna interference researches in ordinary laboratory 结论：以带t7启动子部分双链dna为模板，用t7rna聚合酶体外合成出的shrna产量较高，纯度较好，是一种简便、高效、低成本的短链rna的制备方法，适合于普通实验室用来进行短链rna的合成和rna干扰实验。
Besides the coding specification , avs also developed the file format and real - time transport protocol payload format specifications to enable the application of avs - m video in various services . this paper reviews the high - level coding tools and features of the avs - m coding standard as well as the file format and payload format standards 为了便于在各种实际应用系统中使用avs - m ，还制定了相应的文件格式第九部分第一子部分和avs - m实时传输协议real - time transport protocol , rtp打包格式第八部分第一子部分。
