吐哈盆地三叠纪孢粉地层学及古气候特征

吐哈盆地三叠系划分为韭菜园组、烧房沟组、克拉玛依组和黄山街组，通过对三叠纪地层的孢粉分析，建立了该盆地的四个孢粉组合带，Limatulasporites—Tae－niaesporites—Alisporites组合带、Aratrisporites—Punctatisporties组合带、Punc－tatisporites—Calamospora组合带和Cycadopites—Lophotriletes—Protoconiferus组合带。依据孢粉的演化得出吐哈盆地三叠纪的古气候为早期的干旱温暖到晚期的潮湿炎热。     

高号数高比例粗纺牦牛绒衫加工工艺的研究

报道了高号数高比例粗纺针织牦牛绒衫产品开发的生产工艺。牦牛绒产品的开发前景良好,颇有潜力。但其分梳、纺纱、织衫及后整理等加工工艺有一定的特殊性。文未还对今后的研究方向提供了几点意见。     

Collaborative applications based on the internet

The basic concepts of collaborative applications and some relevant aspects about network communications are introduced. With the examples of some collaborative applications developed by us, several technical problems about collaborative applications, such as loss of data packets, unknown IP address and timedelay, are discussed in detail. And the methods of solving these problems are also provided. Supported by International Cooperation Project (Japan, Jincheng Co. Ltd) Fang Rui: born in 1975, Graduate student     

Mg^＋,Nb^＋离子注入对SnO2薄膜晶粒热稳定性的影响

采用Ａｒ＾＋离子溅射方法将３００ｎｍ ＳｎＯ２薄膜沉积在Ｓｉ片上，分别对膜层进行６０ｋｅＶ，５×１０＾１６ｃｍ＾－２Ｍｇ＾＋离子注入和１００ｋｄＶ，６×１０＾１６ｃｍ＾－１Ｎｂ＾＋离子注入，对未注入，Ｍｇ＾＋离子注入，Ｎｂ＾＋离子注入３种薄膜进行５００℃，４ｈ退火处理．
