My thanks to miles sabin for pointing me at the proc filesystem to resolve problems with chroot ing java on multiprocessor systems 我要感谢miles sabin向我指出了/ proc文件系统,来解决在多处理器系统上chroot java的问题。

Sabin believed that live vaccines , which can replicate somewhat but are too weak to trigger disease , best mimic the protection acquired through natural infection 沙宾认为,活性不足以致病、但仍可复制的活病毒疫苗,最能够模拟因自然感染所产生的保护作用。

Although different approaches to vaccines have been considered ? human versus animal strains , live versus killed viruses , whole virus or protein subunits ? rotavirus researchers followed the lead of albert sabin , creator of the oral poliomyelitis vaccine 疫苗的制作有好几种不同的方式,包括使用人类或动物的病毒品系、活病毒或死病毒、全病毒或蛋白质次单位等;经过考量后,轮状病毒研究人员决定采用小儿麻痹口服疫苗发明人沙宾的做法。

Some typical schemes are implemented via this data structure ( loop subdivision , catmull - clark subdivision , do - sabin subdivision , hybrid subdivision , adaptive subdivision ) . the technique of opengl is utilized to accomplish some basic operations , such as rotation , zoom , pan , pick and so on . finally the algorithms studied by our research group are integrated , and a prototype system based on subdivision surface is developed ( 4 )改进了适合于曲面细分的的翼边数据结构,并实现了典型的细分算法( loop细分、 catmullclark细分、 doo - sabin细分、混合细分、自适应细分) ;采用opengl技术实现了旋转、缩放、平移、拾取等图形的基本几何操作;最后将本课题组研究成果加以集成,开发了一个基于细分曲面的原型系统。
