3.The Gramm-Leach-Bliley Act (GLB Act),which removed the barriers that separated commercial banking from investment banking, merchant banking, and insurance activities, also known as the Financial Modernization Act of 1999, is a federal law enacted in the United States to control the ways that financial institutions deal with the private information of individuals.
1999年11月，美国总统克林顿签署正式颁布了以金融混业经营为核心的《金融服务现代化法》，又称《格郎-利奇金融服务现代化法》(Gramm-Leach Financial Services Modernization Act)，这是20世纪末金融自由化的重大事件。

5.Elimination of Magnesium Oxide in the Platinum Palladium Ore by Acid Leach and Comprehensive Utilization of the Leach Liquor
云南某铂钯矿酸浸除镁及浸出液综合利用研究
6.t was investigated that the Cs leach behaviour of three kinds of cement waste froms, Port-land Cement(PC),Alkali-Activated Slag Cement( AASC)and Alkali-Activated Slag Cementwith Zeolite(AASC with Zeolite), at 293 and 343K. The results show that 28 days cumulativepercent leach of Cs from AASC with Zeolite waste from is one-tenth that from PC waste formand one-sixth to one-fourth that from AASC waste form.
