Mitochondria was relatively little in size. Round primary lysosome with high electron-densed granules and secondary lysosome with high or low electron-densed granules were seen frequently. DCs contained many rough endoplasmic reticulum, the Golgi apparatus and ribosomes. The vacuoles with flocculent electron-densed granules were rare. Some special granules in cytoplasm were seen, whose surface like earphone were covered with a membrane. High electron-densed contents in the granules were near one side and the other side was bright. The nucleus became markedly small in volume, nephroid or hoofed in shape. The nucleus had little euchromatin and lots of heterochromatin under nuclear membrane.

At the same time, the combining intensity between the modified layer and the base with the preoxidized PAN fibers as the reinforcer was stronger than that with the carbon fibers as the reinforcer.

同时，用预氧丝作增强剂得到的改性膜与基体之间结合的强度也明显优于用炭纤维作增强剂得到的改性膜与基体之间结合的强度。

One view is that the nucleocapsids get tegument in the nucleus, and by budding into perinuclear space, they obtain their envelope from the inner lamella of the nuclear membra...

一种意见认为，核衣壳在细胞核内获得被膜，并通过出芽在内层核膜处获得其囊膜后，进入核周间隙，进一步经与核周间隙相连接的内质网，以囊泡转运的方式经高尔基体到达细胞膜，囊泡膜与细胞膜融合，病毒颗粒释放到细胞外。
