The garbage collector moves valid blocks to the tail of the log, skips invalid or obsolete blocks, and erases them (see Figure 2).
垃圾收集器将有效块移动到日志的尾部,跳过无效或废弃块,并擦除它们(参见图 2)。
This is done by using JFFS2 (Journaling Flash File System version 2), which compresses stored data; the 21,544 blocks of storage available hold roughly 60,000 blocks of files.
这是通过使用 JFFS2(Journaling Flash File System version 2)实现的,它会对所存储的数据进行压缩;这 21,544 个存储块可以容纳大约 60,000 个文件块。
Based on some characteristics of decoding and error-floors of low-density parity-check (LDPC) codes, an approach of adding vertical parity-check blocks to original LDPC blocks over GF (2) is proposed.
基于LDPC码在译码和差错平底区域的一些特殊性质,提出了一种为GF(2)域上的LDPC码已编码码字增加纵向校验码字的方法。
When they started to calculate how much rice would be need to fill up all blocks, all the way to 2 to the power 63.
当他们开始计算,需要多少粒米填满所有方格时,从第二格到第63格。
So if we have total +2 and complete shielding -1 where that can actually negate a full positive charge, because remember our nucleus is plus 2, +1 one of the electrons is minus 1, so if it totally blocks it, all we would have left from the nucleus is an effective charge of plus 1.
抵消一个完全的正电荷,因为记住我们的原子核是,其中一个电子是,所以如果它完全挡住了它,我们从原子核中留下的,全部有效电荷就是,所以,在我们的第一个例子中,我们的第一种极端情况。
