查询词典 modified Newton method

Based on a brief review of semiconductor photocatalytic mechanism and researches in the past 30 years on TiO2 heterogeneous photocatalysis, this paper emphasizes that the natural vanadiferous rutile and its modified products, which have not been investigated by either Chinese or foreign research groups, degrade halogenated organic contaminants. By means of grinding, heating in situ, heating, quenching and electron irradiation, the natural rutile could be modified.

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。
