The original desulfurizing process used hydramine solvent to deprivate most H2S, then carried out alkali wash and water wash. But organosulfur removal was so difficult that individual qulity data of liquid gas were instability and below grade, such as copper sheet corrosion. Furthermore, treatment of alkali residue was very difficult.

Firstly, some difficult problems required to be solved,such as the land surface parameters′ calculation and observation over inhomogeneous land surface and development similarity theory which can be applicable to the inhomogeneous land surface. Secondly, studies of the bulk transfer coefficients over humid regions of China must be strengthened. Thirdly, whether or not understanding the landatmosphere interaction process over inhomogeneous and complicated land surface in its entirety, the land surface parameters′ expandedness form local to regional scope is a critical and difficult problem.

在此基础上，探讨了该领域研究中存在的几点科学问题：①需要解决非均匀下垫面地表参数的计算和观测以及发展适用于非均匀下垫面的相似性理论等难题；②对我国湿润地区地表总体输送系数的研究需要加强；③能否对非均匀复杂下垫面陆气相互作用过程进行全面的认识，地表参数由&点&到&面&的推广是关键也是难题。

But the bitter " of " difficult character of the man is not an isolated symptom absolutely, actually, the around of the bitter " in difficult character of occurrence male ", tired of the lumbar genu aching and limp that brings about by kidney empty, mind exhausted body, dazed tinnitus, bosom is fuggy short, insomnia make water of forgetful, frequent micturition tine of drop of drop of urgent, make water, deal with an offender shakes, limb cold Wei is cold wait for all sorts of symptoms to be able to appear in succession, must solve these anguish at the same time.

The results show that jamesonite and pyrrhotite have good floatability in the pH range of 2-10 and marmatite has good floatability in the acid and it is difficult to separate these minerals. In the pH range of 6-8, the separation of jamesonite and pyrrhotite, marmatite is possible when using mercaptoacetic acid and mercaptoethanol as depressants. In case of the presence of Cu2+ ion, however, it is difficult to separate the three minerals. Infrared spectrum demonstrates that there are a number of function groups such as —SH,—COOH,—OH in the molecular structure of depressant.

结果表明：用丁黄药作捕收剂，脆硫锑铅矿和磁黄铁矿在pH 2~10范围内都有良好的可浮性，铁闪锌矿在酸性条件下可浮性好，三者分离困难；在pH 6~8之间，采用巯基乙酸和巯基乙醇作抑制剂，脆硫锑铅矿与磁黄铁矿和铁闪锌矿的分离是可能的；但铜离子存在时， 3种矿物之间的选择性分离是难以实现的。
