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.

脱除花椒籽油中蜡质的合理方法应是：①含蜡量相对较低的精制粗油可选用表面活性剂法脱蜡；②当含蜡量相对较高时，为降低脱蜡过程中油的耗损率可选用分步脱蜡法脱蜡；③需进行碱炼的油，可在碱炼过程中将蜡质与游离脂肪酸一并除去。

The new process for preparing 4,4"-Diaminostilbene-2,2"-disulfonic acid was characterized by carrying out the catalytic hydrogenation of 4,4"-dinitrostilbene-2,2"-disulfonic acid or its alkali salts in presence of both Pd/C and OVN in water, the amount of OVN ranging from 0.1 to 0.2% by weight of 4,4"-dinitrostilbene-2,2"-disulfonic acid or its alkali salts, yielding 98.7% of desired product with 99.3% purity.

确定了氧化缩合反应的较佳工艺条件，DNS收率达95.2％，纯度达到了99.1％。而在本论文所确定的还原反应最佳条件下，DSD酸的收率可达98.7％，纯度高达99.5％。

Its mechanism is the use of anthraquinone in alkali conditions off proton surface forming 10 more stable carbon anion face, but because carbon anion and oxygen ion exist between testosterone and enolate type each other changes, cause reaction product complex, at least five, reaction selectivity, product yield, separation difficulties, and product purity is not high, therefore, using the type and quantity of alkali, phase transfer catalyst type, solvent, to optimize the selection process conditions so as to improve the yield target product.

其机理是利用蒽酮在碱存在的条件下脱去氢质子面形成10位较稳定的碳负离子面进行，但是因为碳负离子和氧负离子之间存在酮式和烯醇式的互变，导致反应复杂，产物至少有五种，反应选择性差，产物分离困难，产率低，且产品纯度不高，因此，利用对碱的种类和量的多少，相转移催化剂的种类，反应溶剂的选择，来优化反应工艺条件从而提高目标产物的产率。

The volatilization of mould powder concludes the evaporation of alkali oxides besides the evaporable fluoride created between the fluorine and acid and alkali oxides. The results of CaO-SiO〓-Na〓O ternary fluorine free slag are: there is a strong relationship between volatilization of Na〓O and basicity R.

对CaO-SiO〓-Na〓O三元无氟渣系的测定结果表明，渣中Na〓O的挥发与碱度R有很大关系，当R＜1时，单位时间内其挥发百分率是恒定的，且受温度的影响不大；当R＞1时，单位时间内的挥发百分率将随其含量的增加而增加。

Under normal temp., PVF2 has a fine corrosion resistance to many organic solvents like halogen, halogenated hydrocarbon, strong oxidant, boiling acid and alkali; UHMWPE has a fine corrosion resistance to inoxidable acid (dilute sulfuric acid, nitric acid and large concen-tration hydrochloric acid, phosphorus acid, hydrofluoric acid, formic acid and acetic acid), ammonia, amine and various alkali and salty solutions. Both materials can't resist the corrosion of strong oxidable acid.

在常温下，PVF2对卤素、卤代烃、强氧化剂、沸酸、碱等多种有机溶剂都有良好耐蚀性；UHMWPE对非氧化性酸(稀硫酸、硝酸及浓度较大的盐酸、磷酸、氢氟酸、甲酸、乙酸)、氨和胺及各种碱、盐溶液都有良好的耐蚀性，两种材料都不耐强氧化性酸的腐蚀。

Besides, The nodulation with else host experiment told us that NWGX035 could nodulate with melilotus suaveolens Ledeb, sophora alopecuroides Linn, lotus corniculatus Linn, sophora viciifolia Hance, trifolium repens Linn. The property of powerful salt, alkali, high temperature endurance and wide nodulation could confirm this strain was a particular strain. The nodulation mechanism and endurance of salt, alkali and high temperature mechanism need to be studied further.

另外，回接其它寄主植物的试验表明， NWGX035能与草木樨、黄化苦豆子、百脉根、狼牙刺和白三叶共生结瘤，其广泛的共生结瘤范围和强的耐盐、碱和抗高温特性可以证明该菌株为一株性状优良的菌株，其共生结瘤机制和耐盐碱机制需进一步研究。
