查询词典 hydrate

通过与其他研究的比较，以临界水合物体积浓度为判断标准定义了一个流动安全区，当管道中的水合物体积浓度小于临界值，可以认为是安全的，相反则认为管道存在水合物堵塞的威胁。

In the northeast part of the South China Sea the high salinity water comes from the Philippine Sea, therefore, biologic productivity was high and there was rich organic matter in sediments during the periods of oxygen-isotopes 2, 4 and 6. In these periods the sedimentation rate was very high, so there were very good material conditions for formation of gas hydrate. In addition, from the end of Miocene to present, the Philippine Sea plate collided with Asian plate in Taiwan area, extruding the northeast part of the South China Sea along northwest direction. The extruding force made fluid in the sediments very active, and this is very good for the formation of gas hydrate.

南海冻北部，在氧同位素2、4、6期，由于菲律宾海的高盐度海水的注入，使这里的生物生产率特别高，陆坡上沉积了丰富的有机物质，加上此期间该处的沉积速率高，为天然气水合物的生成提供了物质条件；另外，自中新世末以来，由于菲律宾海板块与欧亚板块在台湾地区发生碰撞，对南海北部产生北西向挤压，加快了流体在沉积物中的活动，为天然气水合物的生成提供了良好的构造环境。

The regiment of ce is the same as above, but the regiment of cap is (ctx:350 mg/m2,the first day;thp:60~70 mg/m2,the first day;ddp:40 mg,1-3 days) and we need to alkalify and hydrate urine at the same time.
