链密度 meaning in Chinese

chain density

Besides , it was found that compared with cta + , the confined geometry improves the thermal stabilization of methylene chains about 20 in the case of the gallery height less than 9 . 1 a and surfactant content less than 24 . 7 wt % , while the onset temperature of degradation reduces about 25 at high gallery heights and surfactant loadings
较小的受限空间可提高烷基链降解温度20 。随着层间高度和插层物含量增大，起始降解温度下降25 。有机蒙脱土的热失重微分曲线呈多峰，与层间烷基链密度分布呈多层堆积有关。
