结果表明，蚂蟥产卵和孵化的最适温度为25℃，产卵的最佳体重为20g左右；温度能影响蚂蟥产卵前后的体重，而体重大小对产卵前后体重变化影响不明显；当卵重在0.1～2.0g之间时与孵出量成正比，当卵重大于2.0g时孵出量反而有所下降。

The Xujiahe formation in south Sichuan basin is featured by continental clastic sedimentary, thin sand mud interbed, and the welldeveloped sandstone in this area, however, its lithology is tight and its physical properties is poor. In the case of gas bearing, the acoustic velocity difference between the sandstone and the shale is too little to make clear responses on seismic data, as a result, it is very difficult to conduct the gasbearing prediction and to analyze the gasbearing range distribution by means of conventional impedance inversion and hydrocarbon detection.

四川盆地蜀南地区上三叠统须家河组为一套砂泥岩互层的陆相碎屑岩沉积，砂岩发育，但岩性致密，物性较差，砂岩储层含气后的速度与页岩速度相差不大，在地震剖面上无明显的响应，因而采用常规波阻抗反演和含气检测技术不能有效解决该类含气储层识别问题和含气范围展布问题。

Typically these hard waters are found to have high total dissolved solids including sulfates and chlorides, a pH in the range of 7.2 to 7.8, a high content of carbon dioxide (CO2) gas (over 10 parts per million, ppm), and the presence of dissolved oxygen D.O.
