chunking

Giant shovels are biting off big chunks from the hill.

巨型铲土机正把小山头一大口一大口地啃去。

Memory deallocation may be as simple as adding that chunk to the front of the free list, a O(1) operation.

内存的释放也很简单，只是将区块重新加到可的开始，这是一个O(1)作。

In the old days having meat and milk every day often meant a big chunk of the family income.

过去,每天吃肉,意味着要花费掉家庭收入的大部分。

Those chunks of meat are rather large—could you chop them up a bit smaller?

这些肉块相当大, 还能再切小一点吗?

That is, 30-hour chunks of data (which may span 40 hours of clock time due to dropouts) which require a search of a spindown parameter as well as sky position.

也就是30小时的大段数据（由于含有无效信息可能会扩展到40小时），这与天区位置有关。
