In allusion to the need of elemental analysis in the field, three techniques of microbead colorimetry, micro titrimetry and eggshell membrane enrichment colorimetry have been established and forty analytical methods for thirty elements based on these three techniques were studied.
针对野外现场分析的要求 ,选择了微珠比色、微量滴定和蛋膜富集比色三项技术 ,拟定了 30个痕量 (或次量、主量 )元素的 40个分析方法 ;对方法的准确性、精密度、灵敏度等参数与公认可靠方法进行了对比 ,或采用标准物质分析进行验证 ;在方法拟定过程中特别注意了快速方便、降低环境污染、降低成本和提高方法的可操作性。

A field workbox devised by us for microbiological gold searching was introdued.
介绍了新研制的微生物探金野外工作箱 ,它使用方便、准确、快速、灵敏、重复性能好 ,且能定性和定量检测土壤样品中的金。
Based on the law of soil water movement in the unsaturated zone,the study discusses the effect of preferential flow on the movement of the researched soil through a soil column experiment using homemade experimental apparatus in four successive stages-young,middle-aged,mature and over-mature and combining dye-tracer analyses of the field process.
研究采用雷诺数计算及野外示踪映像分析方法,判定证明在所研究地区,有优先流现象发生,优先流是处于层流及紊流之间的过渡流。
