查询词典 sequential estimation

A fully automated simultaneous determination of nitrate and nitrite in water samples by sequential injection analysis based on the Griess diazo-coupling reaction and the formed azo dye for nitrite at 540nm and reduction to nitrite using coppered cadmium column.

用顺序注射分光光度法，通过一次进样。同时测定硝酸根和亚硝酸根。亚硝酸根是根据格里斯重氮－偶联反应，形成偶氮染料后在波长540nm下进行检测。而硝酸根则通过镀铜镉粒还原柱还原为亚硝酸根后进行测定。

The causative agent of the disease is an Corona virus, infectious bronchitis virus IBV）, classified as Corona .Present vaccines for IB are all modified live viruses derived either by sequential passage embrocated chicken eggs. As Immunogenicity of IBV is usually correlated with its virulence, almost all modified live IB vaccines remained insufficient attenuation and have shown a variety of side effects including spread of vaccine virus to no vaccinates, occurrence of long term "carrier" birds, and increasing virulence during in vivo passage.

目前国内外预防本病所用的疫苗大多数是弱毒疫苗，但现用弱毒疫苗都存在以下缺点：（1）与IBV强毒一样，其弱毒疫苗株也能引起潜伏感染，潜伏感染的鸡将终生带毒；（2）疫苗病毒可以由接种鸡传染给非接种鸡，在鸡群之间传播过程中毒力会返强，从而成为新的感染源；（3）传染性支气管炎病毒极易发生变异，且易成为病毒重组的供体和受体，给使用IB传统疫苗预防和根除IB带来极大的困难。
