解釋
插入電位-
In this study, the avermectin - producing strain streptomyces avermitilis was studied and the avermectin biosynthesis gene cluster in the genomic dna of streptomyces avermitilis s - 2 was altered by the method of gene engineering. insertion inactivation of aved gene in the cluster by introducing apramycin resistance gene into aved gene resulted in the disappearance of " a " components of avermectins. when avec gene was inactivated by the same way, four " 1 " components were lost and only " 2 " components, the potential precursor of ivermectin, were accumulated
將該基因簇中的aved基因通過插入外源的安普黴素抗性基因片段使其失活,導致發酵產物中4個a組分(不需要的組分)的消失;將基因簇中的avec基因通過同樣手段,使其失活,導致發酵產物中4個「 1 」組分的消失,而主要積累「 2 」組分(進一步改造可成為伊維菌素的前體b _ 2組分) 。 -
As an planar waveguide component, it has many advantages, such as its small size, lower cost per port, the relatively low insertion losses, potential for volumn production and integration with active elements
作為一種平板光波導型波分復用器, awg具有很多優點:體積小,可批量生產;高通道數,大小可壓縮;較低的插入損耗;單個通道的成本低;還可以與其它功能整合。
