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。

In the "Acid Trip", you can see the auteurism of the Hong Kong director, Kar Wai Wong and Jeff Lau abut "time" and "memory". The hero is amusing and funny, because he wants to show pretty hilarious performance like Jim Carrey and Stephen Chow.

这一部个人动画作品，除画风美式风格以外，粤语发音、故事剧情、叙事方式、表现手法，皆运用经典香港电影中熟悉的元素，在此部动画电影中引用了香港电影两大名导王家卫与刘镇伟对时间与记忆的迷恋，无厘头喜剧片中常见不按牌里出牌的幽默诙谐。

The results show that this strain was a typical acidophile with optimal growth pH being 2.0 for hypha and pH 3.0-4.0 for the spore germination. Peptone was the most suitable nitrogen source which helped produce xylanase induced by xylan during stationary phase. The resultant xylanase reacted best at 50℃-55℃ and pH 3.5, and had activities 70% after 60 min maintenance under optimum reaction conditions.
