Determination of particle size 粒度的测定
The present method has been used for the particle size determination of carbides and metal precipitates in microalloyed steel, middle-alloy steel and high-temperature alloys.
该方法被广泛应用于各种高温合金、中低合金钢、微合金化钢中碳化物、金属间化合物的粒度尺寸分布的测定。
The determination of particle size, together with SEM, XRD, IR, DTA, TG, inverse gas chromatography (IGC)and BET multi-layer absorption techniques were used to characterise kaolin samples.
采用粒度分析、SEM、XRD、IR、DTA和TG、反气相色谱（IGC）和BET多层吸附等测试方法对干粉磨高岭土进行分析测定。
In computing the scattering fields, the determination of the T-matrix involves matrix multiplication and inversion, which consumes considerable time when the size of the particle is large.
在散射场的计算中，T矩阵的计算涉及到矩阵的乘法和求逆，当粒子尺寸很大时，这两种矩阵运算特别是求逆将消耗大量的时间。
