唯宝泊拉斯通（PURE STONE）系列套间——自然为美

大自然的奇花异草、鸟兽虫鸣经常是设计师用以借鉴、获取灵感的创作源泉，在今年法兰克福卫浴展（ISH2005）中不少作品便有向大自然致敬的意味，来自唯宝（Villeroy＆Boch）的泊拉斯通（Pure Stone）系列就是以“石头”作为创作主题，无论是卫浴设备，家具还是配件，一个个都幻化成造型各异的鹅卵石模样，坚实浑圆的外表展现出另类趣味。     

Characteristics of the storage proteins of cotton

The storage proteins of the cottonseed are composed of α and β globulins which are homologous to the vicilins and legumins, respectively, of the legumes. Gene sequences for members of both protein families have been determined, and the derived amino acid compositions are presented here. The proteolytic cleavages and glycosylations involved in the processing of the preproproteins during embryogenesis to yield the proteins found in the mature seed are outlined.     

A comparison of the Low Mode and Monte Carlo conformational search methods

The Low Mode (LM) and Monte Carlo (MC) conformational search methods were compared on three diverse molecular systems; (4R, 5S, 6S, 7R)-hexahydro-5,6-dihydroxy-1,3,4,7-tetrakis(phenylmethyl)-2H-1,3-diazapin-2-one (1), 2-methoxy-2-phenyl-2-triflouromethyl-N-alpha-methyl benzyl propanamide (2) and a trimeric 39-membered polyazamacrolide (3). We find that either method, or a combination of the methods, is equally efficient at searching the conformational space of the smaller molecular systems while a 50:50 hybrid of Low Mode and Monte Carlo is most efficient at searching the space of the larger molecular system.     

新型干法水泥窑节煤剂的研究及工业应用

针对目前我国新型干法水泥窑热耗高的现状,本文从煤炭燃烧、煤炭渗透、矿化作用等方面对节煤剂进行研究,通过煤粉燃烧试验发现节煤剂能降低煤粉粒度从而降低煤粉的初燃点和终燃点;通过渗透性试验发现其能降低节煤剂和煤粉的界面张力,促进节煤剂渗透至煤粉内部,从而有利于其发挥节煤效果;通过矿化试验发现其能降低样品的游离氧化钙,促进固化反应,从而达到节能的目的。通过河南登封SG水泥厂5000t/d的新型干法水泥窑的工业应用试验发现,该厂添加量为0.8‰时到达最佳效果,实物煤耗的节煤率为4.87%,具有较大的经济效益。
