itz

If the actual ITZ thickness is far less than the size of the grain , the ratio of the statistical mean value of the apparent ITZ thickness to the actual ITZ thickness is approximately equal to 2 .

如果实际界面过渡区厚度与粒子的尺寸相比可以忽略的话，截面分析法所得的表观界面过渡区厚度的统计平均值与实际界面过渡区厚度之间的比值约等于2。

The test results showed that Ca ? K and Fe tended to concentrate in the ITZ to different degrees . Si appeared to be of relatively low concentration close to the aggregate surface , but it gradually increased with the distance away from the surface .

试验结果表明：Ca、K和Fe有不同程度地集中于界面过渡区的趋势，而Si的浓度在界面处相对比较低，但随着远离界面其浓度逐渐升高。
