| 4. | Tufa form when underwater springs rich in calcium meet lake water rich in carbonates , forming calcium carbonate , or limestone
由于地下水富含钙，而湖水又富含碳酸盐，于是两者接触便产生出碳酸钙，即石灰石。 |
| 5. | Mono lake ' s tufa are particularly dramatic because water diversions have significantly lowered the lake ' s level , exposing more of the columns
莫诺湖之所以会出现如此独特的景致，是因为分洪使得湖水水位降低，从而露出了更多的石柱。 |

| 8. | The author presume the original physiognomy of jiuzhai valley , and acknowledged changhai valley was a surface - water with uniform waterpower , the rize valley was a branch of it but the inequality rise of lithosphere , the deposit of earthquake landslides debris flows and falling or glacier blocked the river - way , furthermore , the flow water with high content of ca ( hco3 ) 2 , so tufa dyke formed and evolvement the present dyke of lakes the present physiognomy formed on the base of those 2
由于地震、滑坡、泥石流引起的堆积物和冰川作用形成的冰碛物堵塞河道，再加上构造运动造成地壳的不均匀抬升，九寨沟的这种独特的地质环境以及高含ca ( hco _ 3 ) _ 2的岩溶水流作用下，为caco _ 3沉积创造条件，沉积的caco _ 3加高、连接最终形成灰华堤坝，使湖泊的形成成为可能。 |
| 9. | A detailed comparison from both textual and technical angles shows that the rigui tufa ( the drawings and methods of sundials ) by didace de pantoja and sun yuanhua contains basically the same content as both the first part of lu zhongyu ' s manuscript on sundials and johann adam schall von bell ' s and zhu que ' s book with the same title , which in turn are both arguably written by pantoja and sun
摘要文本和技术两方面的细致比较表明，庞迪我和孙元化的《日晷图法》与陆仲玉日晷著作抄本的第一部分以及汤若望和朱确的同名著作内容基本相同，可以认为它们均出自庞迪我和孙元化的手笔。 |
