Mobile alarm unit system based on GSM
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 2
Abstract
In this paper, disadvantages of nowaday mobile alarm units are analyzed, and a new design mobile alarm unit system based on GSM is introduced. This new alarm unit use STC89 series chips which provide high cost-performance, and TC35i communication chips which support GSM/GPRS. It possess the properties that long distance, no noise pollution, and bilateral controlling.

中国土壤重金属(Pb和Cd)沉降临界负荷区划
用稳态法确定了中国土壤的重金属Pb和Cd沉降临界负荷，结果表明我国土壤临界负荷明显呈现东南高、西北低的分布特征。我国东南部地区普遍能够接受大于1.0 g•hm-2•a-1的大气Pb沉降和大于0.1 g•hm-2•a-1的Cd沉降，原因是栽培植被和天然植被的...
