用直接染料替代碱性染料降低水污染

直接染料对纤维素有强的亲和力，耐光性好，水中残留少；碱性染料着色能力强，价格低，但水污染严重。从环保考虑，应该用直接染料替代碱性染料。

小巧精致——明基Joy Bee DA120 MP3播放器

打开包装，翻开琳琅满目的附件，小小的MP3机才出现在眼前。拿到手的第一感觉：四个字——小巧精致!桔红色纯金属外壳，简单长方体造型，亮银按钮，表面拉丝金属Logo。整个机器简约、小巧、精致，完全给人一种高档时尚产品的感觉，笔者不由得联想到了ZIPPO这个经典品牌的打火机，两者的造型、大小、精致都有共同之处。     

Formation of composites fabricated by exothermic dispersion reaction in A1-TiO2-B2O3 system

The formation of aluminum matrix composites fabricated by exothermic dispersion reaction in A1-TiO2-B2O3 system was investigated. The thermal analysis results show that the reactions are spontaneous and exothermic. The Gibbs free energy of α-Al2O3 is the lowest among all the combustion products, followed by TiB2 and Al3Ti. It is noted that when the B2O3/TiO2 mole ratio is below 1, the reaction products are composed of particle-like α-Al2O3, TiB2 and rod-like Al3Ti. The α-Al2O3 crystallites, resulting from the reaction between A1 and TiO2 or B2O3, are segregated at the grain boundaries due to a lower wettability with the matrix. SEM micrographs show that rod-like Al3Ti phase distributes uniformly in the matrix. When the BEO3/TiO2 mole ratio is around 1, the Al3Ti phase almost disappears in the composites, and the distribution of α-Al2O3 particulates is improved evidently.     

赫哲族以鱼为生

提起吃鱼最多的民族，人们自然会想起日本。不错，日本人是全世界吃鱼量最多的人。然而在我国，也有一个民族的食鱼量能与他们匹敌，这个以鱼为生的民族就是赫哲族。随着社会的发展，赫哲族已经从事多种生产经营方式，但是他们仍旧保留着吃鱼的传统。[编者按]
