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.

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.     

用于CIMSERC网络性能评价的NPES设计与实现

分析建模的方法用于CIMS网络性能评价是有其局限性的。本文介绍的是一个基于仿真方法的CIMSERC网络性能评估模拟器——NPES的设计与实现。该NPES可作为进行CIMSERC网络性能评价的“实验床”和评估工具.CIMSERC网络的基本结构是二个互连的基于Ethernet的TCP/IP网,设计中用于观测和评价的性能指标包括:网络系统的吞吐量、利用率、以及信息包传输延迟等。CIMSERC的NPES用SIMAN和FORTRAN语言混合实现。

用正交试验法确定最佳调剖施工参数

针对文明寨油田地质特征和开采现状，按照油藏数值模拟原理，以调剖井对应油井的增油降水创经济效益大小为考核指标，运用正交试验的均衡分散性和整齐可比性及Ｌ９（３４），正交表进行调剖最佳施工参数试验．经现场试验、分析、讨论发现：影响调剖效果的主要因素是措施半径，其次为施工排量和注入方式，且最佳施工参数是措施半径在３．５ｍ左右，施工排量在１９ｍ３／ｈ左右，按连续注入方式调剖。经文明察油田、卫城油田、马寨油田５０井次现场试验证明，较好地改善了注水井吸水剖面，对应油井取得了明显的增油降水效果，收到了较好的经济和社会效益．
