Therefore, on most architectures, a find-first-bit-set instruction is used to find the highest priority bit set in one of five 32-bit words (for the 140 priorities).

因此，在大部分体系架构上，会使用一条find - first - bit - set指令在5个32位的字(140个优先级)中哪一位的优先级最高。

The most obvious issue is that the interface in Listing 6 requires a JNI call for each bit set or retrieved, as well as a JNI call to read a byte from, or write a byte to, the serial port.

最显著的一个问题就是，清单6中的接口在设置或检索每个位，以及从串行端口读取字节或者向串行端口写入字节都需要一个JNI调用。

If two interrupts' bitmasks had the same first bit set, then both interrupts were processed on the same CPU indicated by the first set bit.

如果两个中断的位掩码中设置的第一位相同，那么这两个中断都在这一位指定的CPU上处理。

And we're actually going to get a little bit deeper in our clicker questions here, since when you do your problem-set it won't be quite this straight forward that you'll be answering this kind of question, but actually you'll be thinking about how many different orbitals can have certain state functions or certain orbital names.

事实上我们要讲的,比这个问题还要深一些，因为当你们做习题集的时候,你们不会遇到这么明显的问题，而是要考虑有多少个轨道,有某种特定的态函数,或者特定的轨道名字。
