核流（streaming of nuclear）：在电极伤中，显微镜下，有时可见 基底细胞线状伸长，插入真皮中，称流水样结构或核流。
有人喻之 为流水样结构或称核流(streaming of nuclei)(图16-8)。毛囊、汗腺与毛细血管内皮细胞 亦呈极性化，核变细长、深染(图16-9)，汗腺与毛细血管腔扁塌，甚至变成实体状细胞条索。

这里有一个需要权衡的因素：每个核的线程多有利于并行处理，而线程少能够提高单一处理流的性能。
There’s a trade-off factor in place here: either have more threads per core for concurrent processing or fewer threads, which will ultimately boost single-stream performance.
这次测试是在一个Windows XP双核笔记本计算机上执行的，使用DB 2 V 9.1代码库，模拟几个只由connect语句组成的DB 2命令行处理程序作业流。
This test was performed on a Windows XP dual-core laptop, using DB2 V9.1 code base, simulating several DB2 command line processor job streams that consisted exclusively of connect statements.
这是一种用于示出核因其正在指令流错的误分支上工作而没有做出许多“有用”工作的良好指示器。
This is a good indicator to show that the core is not doing lots of "useful" work since it is working on the wrong branch of instruction stream.
