The absorption, emission maximum and the fluorescence lifetime changed as the Hammett substituent constant in folding linear.
最大吸收、最大发射、及荧光寿命与取代基的哈密顿取代基常数呈折线关系。

The experiment is conducted in two cases, one with constant load and another with constant loading rate. Experiment results of acoustic emission monitoring of different cases are analyzed.
试验分恒定载荷和加载速率为定值两类情况进行，分析了试样在不同情况下的声发射监测试验结果。

This is because the different levels of CO2 emission intensities in different regions resulting from different causes is not a constant or evaluated using constant variables.
