二次水 meaning in English
secondary water
Examples
- The air conditioning or heating water systems with primary water system in heat source or cold source side and secondary water system in load side divided by direct connection mode need to adopt connectors or water mixers
摘要用直接连接方式划分热源（或冷源）侧一次水和负荷侧二次水的供暖或空调水系统，需要采用连通器或混水器。 - As far as the metal bo are concemed in this thesis , na + , k + in the thet main any , mgl in the second main any and miz + of the transient elements in the fourth period are of tather good therovement to the ffe - fodrig propeny of mse . ( 3whth the teehnology of lb , the monolayer of hise was deposited on to caf2 with hydrophilic sums on ultiapure water subphase , thus y - type lb fllm of transfer raho approaching to l is obtained . the lb film is demonstrated with ft - ir spectrum
( 3 )利用lb技术将二次水亚相上的hise单分子膜沉积到具有亲水表面的caf _ 2基片上，得到转移比接近1的y ?型lb膜，并用ft - ir光谱对lb膜进行了表征，发现hise的红外吸收峰在制成lb膜前后没有发生位移，随着lb膜膜厚的增加，吸收峰呈现增强的趋势，表明lb膜可有效、均匀地沉积。 - The characteristics of samples were investigated using xrd , hrtem , n2 adsorption technique and so on , and it was shown that mesoporous silica mcm - 41 had been synthesized in this work with uniformly sized pores and long - distance ordered arrangement of hexagonal structure , and the pore size was about 2nm , and could be regulated by the second hydrothermal treatment or the addition of l , 3 , 5 - trimethylbenzene ( tmb ) as organic assistant expander
结果表明合成试样孔径尺寸单一，六方孔道排列，具有良好的长程有序结构，孔径为2 . 1nm ，为典型的有序介孔结构。并通过二次水热处理和添加有机辅助剂1 ， 3 , 5 -三甲苯( tmb )对合成mcm - 41的孔径进行调节。
