Because of a high groundwater level and a strong erosion action, the coal formed in a low peat swamp is great in gelatification index and in groundwa ter index, which are in a negative correlation to the ratio of clean coal recove ry. While for the high peat swamp, IG and IGW are small, corresponding to a high ratio of clean coal recovery.

低位泥炭沼泽由于潜水位较高，水流对泥炭沼泽表面的改造和冲刷作用较强，形成的煤层具有较高的凝胶化指数和地下水流动指数，并且与精煤产率呈负相关，煤中粘土矿物和黄铁矿难以洗选；高位泥炭沼泽形成的煤层具有较低的凝胶化指数和地下水流动指数，泥炭积累速度较快，其精煤的产率较高。

Here is an astounding fact: Neither the worker in the oil field nor the chemist nor the digger of graphite or clay nor any who mans or makes the ships or trains or trucks nor the one who runs the machine that does the knurling on my bit of metal nor the president of the company performs his singular task because he wants me.

这真是令人惊异的事：油田工人或化工师家，或石墨、粘土开采工，或者是制造轮船、火车、卡车的人，或者是操纵机器生产金属箍上的滚花的工人，或者是铅笔制造公司的总裁，所有这些人，都不是由于本人需要我而干自己的那份工作的。

I can not make it blossom and suits me
