Environmental Friendly Route and Wool Shrink Proofing

The shrink proofing on wool with treatment of protease named Argaenzyme STL was studied. The various pretreating auxiliaries, different parameters for protease treating process and the effect of stabilizer were discussed in detail. The varieties of some properties before and after protease treatment were also investigated.

A new class of variational equation problems

Abstract Applying an analysis method to a group of multivariable equations, a new class of variational equations are proved. Thismethod is more concise and more direct than the others. This result can be applied to some stochastic control models.

The influence of chronic nicotine treatment on stress-induced gastric ulceration and emptying rate in rats.

Ten-day treatment with nicotine (5, 25 or 50 micrograms/ml drinking water) dose-dependently intensified gastric ulceration induced by cold-restraint, and emptying rate. Stomach contractions produced by graded doses of bethanechol i.v. were elevated further by nicotine treatment. It is suggested that chronic nicotine administration produces hypersensitivity of the gastric muscarinic receptors; stomach hypermotility contributes to the ulcer-worsening action of the alkaloid.     

伞花木染色体核型的研究

本文首次报道了国家二级保护植物伴花木（无患子科）的染色体数目，并对其核型进行了分析，结果表明：该种染色体的核型公式为：Ｋ（２ｎ）＝２２＝１６ｍ＋６ｓｍ，染色体属较对称的“２Ｂ”型。     

粉末冶金陶瓷模工艺中的快速脱蜡新技术

粉末冶金陶瓷模工艺是一种先进的过净形成形工艺．本文报道该工艺中一种新的脱蜡技术．采用快速加热、管径集中热量和定向导热传热综合方法，在陶瓷模和大部分蜡模材料处于较低温度下，使蜡模材料来不及发生显著的热膨胀而直接蒸发，得到脱蜡干净、外形完整的陶瓷模．
