查询词典 memory size

It reallocates only once, to 65536, rather than just to the size needed, so it can be less memory-efficient than Chuck's patch (though, like his patch, it only reallocates if the response is larger than PACKETSZ, which defaults to 512 bytes). After reallocating, it forces a TCP query, rather than requiring the resolver library to do so (avoiding an extra round-trip between qmail and the name server, though if they're on the same machine or local network this is not a big worry).

它仅仅重分配一次缓存为65536字节，而不是分配正好需要的大小，所以它可能比Chuck的补丁内存效率低一些(虽然如此，像Chuck的这个补丁仅在反馈长度大于PACKETSZ--默认为512字节--情况下重分配缓存)重分配之后，它强制一个TCP查询，而不是要求解析库来作查询(尽管在qmail和名字服务器同在一个机器或者同在一个局域网络里面的情况下，这种查询不算什么负担，这样作还是避免了在qmail和名字服务器之间额外的往返)。

However, the size of the SP memory per TU can be reconfigured during boot time.

因此，高速缓存是由每个缓存片保留的缓存总数决定。

There is no limit to the size of n or m, but large numbers will chew up more memory and slow down r.e. execution.

对n和m没有大小的限制，但是数字太大会导致内存占用增加并且正则的速度变慢。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
