The ORF2 gene is the most important protein-code gene for porcine circovirus, and is the main gene differing porcine circovirus typel from porcine circovirus type2 (PCV2). To construct a specific PCR detecting method, we designed a pair of primers to amplify a partial fragment of ORF2 gene from PCV2, referring to fifteen strains complete genome published in Genbank. The PCR product was about 0.67kb in size detected by gelose gel electrophoresis.

猪圆环病毒的开放阅读框2(ORF2)是其主要结构蛋白的编码基因，也是区分猪圆环病毒1型(PCV1)和猪圆环病毒2型(PCV2)的重要基因，本研究参照GenBank已发表的15株PCV2基因序列，设计合成一对引物，对PCV2的ORF2基因进行PCR扩增，产物经琼脂糖凝胶电泳，呈现一条大小约0.67kb的特异条带，经条件筛选，建立了猪病料中PCV2感染的PCR检测方法。

Packaged within geminate particles, the genomes of geminiviruses are single-stranded circular DNAs that are replicated mainly by a rolling circle mechanism, characteristic to prokaryotes. Previous researches have indicated that geminiviruses can generate various DNA replication forms in bacteria, suggesting that geminiviruses possess the potential to regulate the expression of certain viral genes in prokaryotic systems.

双生病毒在植物细胞中是主要以原核生物形式的rolling circle replication方式做复制，而先前研究指出双生病毒可以在原核系统里进行复制，因此，双生病毒基因体中应具有在原核系统中亦能表现的调控机制，除了已知的基因外，是否有其他未知的基因参与这项机制仍不清楚。

After years of research, exploration, the successful realization of Scleroderma guani, Zhou's rodents wasps, Trichogramma, Anastatus Bee, Lai aphid wasps, pulp Kok aphid wasps, Coccinella septempunctata, grass Chrysopa septempunctata, Yang Fan-moth virus, Lymantria dispar virus, the virus, such as spring geometrid more than 10 natural enemies of insect pathogens and insects breed of industrial production.

经多年的研究、探索，已顺利实现管氏肿腿蜂、周氏啮小蜂、赤眼蜂、平腹小蜂、丽蚜小蜂、浆角蚜小蜂、七星瓢虫、草蛉、杨扇周蛾病毒、舞毒蛾病毒、春尺蠖病毒等十几种天敌昆虫及昆虫病原体的周年工厂化繁殖生产。

Rubella virus, the etiological cause of German measles, is the only member of the Rubivirus genus within the Togaviridae family.

风疹病毒(rubella virus，RV)是披膜病毒科风疹病毒属的唯一成员，人类是RV的唯一自然宿主。

That means this morning's flu is a parent by the afternoon, a grandparent by the evening, and a great-grandparent by the next day.

这意味着，到了下午，早上的病毒已经繁殖了一代，到了晚上，第三代病毒已经在生长，第二天是，病毒已经繁殖了四代。

Trojan Guarder will start a system called Ghost monitoring program to monitor all system memory to run the program, all open local files, real-time search Trojans and worms, Trojan horses and worms in time, it will hide other programs, immediately the eradication of the virus.

Trojan Guarder 将会启动一个名为Grard Ghost的系统监控程序来监控所有在系统内存中运行的程序，所有打开的本地文件，实时的搜索特洛伊木马及蠕虫病毒，当特洛伊木马及蠕虫病毒出现的时候，它将会隐藏其它程序，立即把病毒消灭。

Once a trojan or worm appears, even it is hidden in other programs, Trojan Guarder will display a signal for warning and eliminate it consequently.

Trojan Guarder 将会启动一个名为Grard Ghost的系统监控程序来监控所有在系统内存中运行的程序，所有打开的本地文件，实时的搜索特洛伊木马及蠕虫病毒，当特洛伊木马及蠕虫病毒出现的时候，它将会隐藏其它程序，立即把病毒消灭。

Harald zur Hausen demonstrated novel properties of HPV that have led to an understanding of mechanisms for papilloma virus-induced carcinogenesis and the predisposing factors for viral persistence and cellular transformation.

哈拉尔德楚豪森显示性能的新型病毒，导致理解的机制乳头状瘤病毒引起的致癌和诱发因素为病毒持续和蜂窝转变。

Due to the antigenic variation of viral surface proteins, hemagglutinin and nuraminidase, the vaccine has to be evaluated and adjusted every year.

目前所使用的流行性感冒病毒疫苗因为主要是以去活性的病毒所组成，但归因於病毒表面蛋白质HA及NA的抗原变异性太大，需要每年进行评估及调整。

Reporter from the country 863 plans " the real time that is based on program behavior to parse judgement independently defends technology " the understanding on this seminar that task group holds arrives, the computer virus in the past a characteristic is " caustic person is not hoggish ", virus fabricant does not get real benefit in the hope transmission from virus.

记者从国家863计划"基于程序行为自主分析判断的实时防护技术"课题组召开的这次研讨会上了解到，过去的计算机病毒一个特点是"损人不利己"，病毒制作者并不指望从病毒的传播中得到实在的利益。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
