轻松解决板载网卡故障

我的主板为nForce430芯片组,集成了Nvidea,nForce千兆网卡,主板上安装了一声PCh电视卡,前段时间电脑中毒了,硬盘晨的文件都被感染了,所以直接重新分区,格式化,重新安装Windows XP,但驱动光盘找不到了,而Windows XP没有自带网卡驱动,此时无法上网了,但板载网卡的指示灯是正常亮的,为了可以马上上网,我打来一声8139D PCI网卡替代板载网卡,但接下来各种问题就随之而来。     

动漫的崛起不再是个冷笑话

中国动漫产业正在崛起,也涌现出了一大批相当不错的作品。但是,现在中国动漫产业还存在着诸多不规范的地方。大家在为这些优秀作品鼓掌的时候,也别忘了给其他作品多一些鼓励。而动漫从业者们也不要沾沾自喜,大家还有很长—段路要走。中国动漫正在崛起,这是一个进行时……     

Radiation effect of neutrons in a reactor on polyurethane

The radiation effect of neutrons in a reactor on polyurethane was studied. The gases produced by irradiated samples were analyzed by gas chromatography, and the dynamic mechanical and compression properties of the samples were also studied. The positron annihilation lifetime of irradiated samples was measured at room temperature in vacuum. The experimental results indicate that gas chromatography is a powerful tool to quantitatively analyze the gas products from neutron-irradiated polyurethane and characterizes the chemical changes in the sample. And the changes in microstructure determined from the PAL correlate well with the measurements of the mechanical properties by dynamic mechanical analysis (DMA).
