Pokeweed antiviral protein belongs to Ribosome-inactive Proteins. PAP has potent antiviral activity against many plant virus. pT1 was used as the template to amplify the deleted mutant PAP gene (N-deleted and N-,C-deIeted) by PCR and then the two genes were cloned into expression vector. Different IPTG-inducible expression vector containing different deleted mutant PAP gene was constructed and transferred into E.coli strain BL21 (DE3)-plysS.

美洲商陆抗病毒蛋白是一类能很好的抑制植物病毒的蛋白，很早就有报道低剂量的商陆叶片粗粉末就能明显的抑制TMV在菜豆叶片上局部枯斑的形成，PAP缓释剂也已用于病毒病的防治工作，但美洲商陆抗病毒蛋白属于核糖体失活蛋白，它对生长的细胞会有一定的毒性。

Viruses that are pathogenic for specific insects include nuclear polyhedrosis viruses, granulosis viruses, and cytoplasmic polyhedrosis viruses.

对特定昆虫有致病作用的病毒包括：核多面体病毒，粒病毒和细胞质多面体病毒。

Up to on December 31, 2007, jiang Min turns over virus center to intercept and capture new virus in all more than kinds 360 thousand, relatively annual grew 601% 2006, among them the virus of 78% above is trojan, postern virus.

截至2007年12月31日，江民反病毒中心共截获新病毒36万余种，较2006年全年增长601%，其中78%以上的病毒为木马、后门病毒。

The Ids RNA or siRNA obtained by said invention is mixed with hepatitis B virus expression vector in proper proportion, and injected into the mouse body by vane caudalis hydraulic pressure method, and its result shows that the non-homologous sequence IdsRNA and siRNA basically do not inhibit the replication of hepatitis B virus in mouse body, and these RNA molecules are mixed with hepatitis B virus gene.

将本发明得到的ldsRNA或siRNA以适当的比例与乙型肝炎病毒表达载体混合，并用尾静脉液压法注射到小鼠体内。结果显示非同源性序列ldsRNA和siRNA基本不抑制乙型肝炎病毒在小鼠体内的复制，而与乙肝病毒基因同源性的ldsRNA和siRNA可以有效抑制乙型肝炎病毒在小鼠体内的感染复制，抑制率高达90％以上。

There are also interactions with several viruses including Swine Influenza Virus, Pseudorabies, PRRS,PCVII

还和几种病毒相互作用，其中包括猪流感病毒、伪狂犬病毒、蓝耳病病毒、圆环病毒II型

Methods Sindbis virus, Pseudorabies virus and poliovirusl (PV1) were used as indicated viruses in this test.

将Sindbis病毒、伪狂犬病毒和脊髓灰质炎病毒(PV1)3种指示病毒分别加入不同的UTI原料样品中，进行60℃水浴10h和乙醇处理3h，处理不同时间后分别取样，用微量细胞病变法检测不同时间段样品中的病毒残留滴度。

The first-way shows that the virus can be inactivated firsthand by the flavonoid compound; The second-way shows the flavonoid compound can inhibit virus replication by inhibiting the activity of ptyalin; The third-way reflects the flavonoid compound can interdict adsorption.

第一种给药方式说明黄酮类化合物可以直接灭活H5N1病毒；第二种给药方式说明黄酮类化合物可通过抑制流感病毒唾液酶的活性，从而抑制病毒粒子的复制；第三种给药方式反映一定浓度的药物可以阻断病毒对细胞的吸附作用。

It is reported, CIH1.2 virus is file virus, it is the first virus that can destroy computer hardware, virus can destroy the complete information on user system, below certain circumstance, can rescript systematic BIOS, bring about toxic computer advocate board be destroyed with hard disk, cause computer to cannot be started, the data on hard disk is missing.

据悉，CIH1.2病毒为文件型病毒，是历史上第一个可以破坏电脑硬件的病毒，病毒会破坏用户系统上的全部信息，在某些情况下，会重写系统的BIOS，导致中毒电脑的主板和硬盘被破坏，致使电脑无法启动，硬盘上的数据丢失。

Purified virus was observed by Electron microscopic,we finded the average size of the isolated virus was 70~80 nm,rotundity ,without viral envelope. The result showed that isolated virus was porcine circovirus.

将病毒纯化后进行电镜观察，病毒粒子直径约17nm，圆形，无囊膜，研究结果表明分离的病毒为猪圆环病毒。

Purified virus was observed by Electron microscopic,we finded the average size of the isolated virus was 70-80 nm, rotundity ,without viral envelope.

结论将病毒纯化后进行电镜观察，病毒粒子直径约17nm，圆形，无囊膜，研究结果表明分离的病毒为猪圆环病毒。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
