The layer of solid KCl is so thin in depth日韩视频免费福利片在线、so small in size、 and so low in grade that it is too difficult to exploite it. Besides that, only 1/3 of the liquid KCl can be expoi ted due to the mining method of well and canal drainage which is being used now. Therefore, it is one of the key problems to exploite the liquid KCl as possible as we can and to turn the solid KCl into explo itable liquid deposit in Qarhan salt lake. So the idea of dissolving and driving exploitation has been suggested. This paper will deal with three problems as follow

In this paper an innovative method for machining sculptured surfaces is presented. By using a disc cutter with a concave end instead of traditional ball-ended or drum-shaped tools, and adjusting the cut- ted axis to swing relative to the component being machined under some special rules, the envelope formed by the trace of the tool-nose may have the same derivative up to the third order as the required theoretical surface.
