n.穿透性；滲透性；透徹性

The required water in the normal constituency of cement paste will be determined by testing penetrability of the cement paste with different water contents. 通過試驗(yàn)不同含水量水泥凈漿的穿透性，以確定水泥標(biāo)準(zhǔn)稠度凈漿中所需加人的水量。

The reason of air distribution being asymmetric is that the penetrability of the field soil is not uniform. 現(xiàn)場曝氣存在氣流分布不對(duì)稱現(xiàn)象，是由于土壤介質(zhì)的滲透性不均勻所致。

n.不能貫穿；不可入性；不可測知
