双掺 meaning in English
doubledoped laserr
Examples
- In this paper , in term of low water - binder ratio , high - volume fly ash concrete with chemical admixture is produced
本文采用双掺(掺粉煤灰和高效减水剂) 、低水胶比的技术路线，配制高掺量粉煤灰混凝土。 - Recently , cr4 + and laser ion co - doped self - q - switched crystals are very attractive . the behavior of self - q - switched dpssl has been investigated by numerical simulation according to the rate equations of solid - state lasers
近年来，人们对于cr4 +离子和激光增益离子双掺的晶体做成的自调q激光晶体已经产生了广泛的兴趣。 - The influence of the heat treatment on the in - situ synthesis process and the luminescence behavior of the rare earth complexes in the different ratio teos / gptms gel glasses have also been studied
研究了双掺lmol h共和3molohy的teos凝胶体系和50 teos50 gptms凝胶体系，考察了ph值对稀土有机配合物在上述两种凝胶体系中原位合成及发光的影响。 - With the increase of the gptms , the luminescence intensity of l . omol % eu3 + and 3 . 0mol % dbm co - doped gels increase gradually , which indicated that the increase of the gptms promoted in - situ synthesis of the dbm : eu3 + complexes in the gels
在不同比例的gptms / teos凝胶中双掺dbm和eu ~ ( 3 + ) ，随着gptms在基质中浙江大学研士学过被文所占比例的升高，稀土有机配合物在其中的热衰减温度亦逐渐降低。 - The influence of polypropylene fiber , expansion agent and both of them on moisture expansion and dry shrinkage of the filled wall were systematically tested . the testing results and theoretical analysis slowed that polypropylene fiber was the most beneficial to restrain it ’ s moisture expansion and drying shrinkage , however , the block doubly blended with polypropylene fiber and expansion agent can most beneficially improve crack - resistance of wall filled with the stone ballast block , at the
试验结果和理论分析证明上述试验结果及理论分析,即单掺聚丙烯纤维、单掺膨胀剂和双掺聚丙烯纤维与膨胀剂均能限制混凝土空心砌块的湿涨干缩,其中,聚丙烯纤维的限制效果最好;但是,膨胀剂的补偿收缩与聚丙烯纤维的限缩联合作用使得双掺砌块更有利于增强混凝土空心砌块填充墙的整体抗裂性能。
