A team of researchers led by NIAMS' Alasdair Steen, Ph.D., working with a ersion of the seasonal H3N2 strain of influenza A irus, has been able to distinguish fie different kinds of influenza irus particles in the same isolate and map the distribution of molecules in each of them.

NIAMS 的Alasdair Steen博士领导的研究团队成功分辨出流感A病毒的季节性H3N2病毒株的5种不同粒子，并已绘出这5种粒子的分子分布图。

The virion can be seen in the cerebellum,cerebrum and spleen.

电镜观察，可见大脑和小脑神经元的胞浆和胞核均发生明显病变并可见病毒粒子存在。

With electron microscope, the virion observed is oval, and the size is 267nm×103nm.

脂肪体超薄切片中的病毒粒子呈椭圆形，大小为267nm×103nm。

In this paper, vp76 was expressed in Escherichia coli and used to prepare a specific antibody to determine the location of the corresponding protein in the intact virion, the nucleocapsids and the envelope of WSSV.

本文在大肠杆菌中表达了VP76并用表达产物制备了VP76的多克隆抗体，它能特异识别完整病毒粒子、核衣壳和囊膜上vp76。

Diameter of polyhedron is 0.36～1.3Mm, size of virion is 326 nm×69nm.

多角体直径0.36-1.3μm，平均1.02μm，病毒粒子大小为326 nm×69nm。

Virions wereobserved in the vescles of PAMs at 28 DPI.

It is a very important progress that a new procedure was developed using a re-formative gradient medium and by ultra-centrifugation for the isolation and purifi-cation of intact WSSV viral particles from the infected penaeid shrimp or crayfish.

在完整WSSV病毒粒子纯化技术上取得重要研究进展。采用改良的密度梯度离心介质建立了一套成熟的WSSV纯化方案。

SiRNAs were tested for silencing expression of the major capsid protein encoded by tiger frog irus, an iridoirus causing seere disease in fish. siRNAs targeting mcp gene effectiely inhibited TF replication in fish cells as demonstrated by reduced mcp RNA leel, postponed emergence of cytopathogenic effect, as well as reduced TF titer and particles in cells.

TF的MCP基因编码一个主要衣壳蛋白，通过转染针对MCP基因的siRNAs能减少了MCP基因RNA水平，从而沉默MCP基因表达；在FHM细胞上延迟了CPE的出现，降低了TF的滴度和病毒粒子的数目。

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。
