变变

However, among the variables are associated with school educational resources , excellent school academicism has a positive effect and the times of teachers' in-service training programs has a negative effect on students' academic achievement, other variables are not highly related to academic achievement.

Many data and discussions about carbonate rock dissolution in CO2 solution have been published. In this paper, special simulation experiments were carried out in order to understand the dissolution behaviors of carbonate rocks in organic acid and H2S solution. The results show that, as the temperature rises from 20℃ to 200℃, the dissolution rate of carbonate rock in organic acid increases with temperature below 90℃ and decreases above 90℃.

CO2对碳酸盐岩储层的溶蚀作用已有不少学者进行了研究，本文则以一个全新的模拟实验方式对不同类型碳酸盐岩在有机酸和H2S水溶液中的相对溶蚀能力进行了研究，结果发现随温度从常温升高至200℃，有机酸对碳酸盐岩的溶蚀能力由弱变强再变弱，在90℃左右溶蚀能力最强。
