In terms of data on staging sowing experiments with two line hybrid rice Liangyou Peijiu in Nanjing and Zhenjiang,five critical stages in which high yield could be achieved were chosen.

Kl203 well is an abnormal high pressure and high production well, of which operating risk is very big, especially is well control.

,sulfur content,high pressure,and high production,during the operation works of which there will encounter many great unexpected difficulties with high risk and large possibility of serious environment damage.

In this paper, the authors have analyzed the main controlling factors that affect enrichment and high production of coalbed methane (CBM), such as generating and storing capacity of coal rock, permeability of coal reservoir and preservation conditions of CBM.
