vari-size grained 不同粒度的
This opens up the prospect of configuring VGs with a relatively small number of disks and fine-grained storage allocation options through a large number of PPs, which are small in size.
这使得我们能够通过较大数量的 PP,以较少数量的磁盘和细粒度的存储分配选项来配置 VG,其中这些 PP 的容量很小。
Impermeable formations, such as shales and siltstones, tend to be finer grained or of a mixed grain size, with smaller, fewer, or less interconnected pores.
不渗透的地层如页岩与粉砂岩。因颗粒很细或粗细颗粒混杂。只有较小,较少连通不好的孔隙。
Countercurrent type separators not suitable for dealing with coarse grained ores, because the magnetic particles size thick, easy to jam sorting sedimentary space.
逆流型磁选机不适宜处理粗粒矿石,因为粒度粗,矿粒易沉积从而堵塞选别空间。
