Geochemical characteristics of more than 10 cores from the marginal seas of the WestPacific Ocean have been studied and anomalous enrichment of Mn at some layers in thecores, specially at the top of the cores, has been found. Here K_1 is defined as thecoefficient of relative enrichment of Mn at a layer (the content of Mn at a layer/the aver-age content of Mn in a core), K_2, as the coefficient of enrichment of Mn at a layer(thecontent of Mn at a layer/the average content of Mn in shallow sea deposit) in order to

“互联网 ”被写入政府工作报告，这是第一次，也比过去任何一次将信息化说得都具体形象，更让人们展开想象的翅膀，这就是互联网的魅力。在这个信息化与科技化交融发展的大时代，我们不能让自己的智慧与能力与“互联网 ”擦肩而过。这是个千年难遇的机会，也许这种冲击力和新动力的影响是难以估量的，中国已经无可争议地站在超越的起点上。 “互联网 ”的畅想版本 互联网作为一种平台工具，从其诞生之日起，一直都存在各种
