The results indicated that the ree tracer technology has high precision to quantify the spatial - temporal process of soil erosion ; in earlier rainfall course, the development degree of sheet and nil erosion was general equation ; otherwise in the following course, the rill erosion was dominant in the total erosion, its average erosion acceleration and the average erosion rate was 15 and 9 times of sheet erosion, respectively ; in the end of experiment, the rill erosion took up 90 % of total erosion amount ; the section of slope bottom occupying about 1 / 3 slope area was active erosion segment in this experiment
結果表明： ree示蹤技術對定量研究土壤侵蝕具有較高的精度；降雨前期，片蝕與細溝侵蝕發育程度基本相當；後期細溝侵蝕占據坡面侵蝕的主導地位，其侵蝕平均加速度和平均侵蝕率分別是片蝕的15倍、 9倍；試驗結束，細溝侵蝕占據坡面總侵蝕的90 % ；本試驗條件下，坡面下1 / 3區域為侵蝕活躍帶。 -
The high - order finite element methods are used to obtain high accurate solutions of the steady flows. characteristics of the chaotic mixing are analyzed by numerical simulation and experiment through examining of the asymptotic coverage of a passive tracer

Ventilation function and tracer - gas decay theory are applied to design the experiment. in the experiment, velocity and carbon dioxide concentration are measured and carbon dioxide time - levels in different experimental cases are obtained. also, the effect of moving people in experimental room on contaminant field is analyzed and subjective feelings are investigated
本課題首次以旋流通風方式為研究主線，運用通風方程和示蹤氣體衰減理論設計實驗方案，對旋流通風方式下普通會議室的速度、二氧化碳濃度進行了測試，分析了人員隨意走動對濃度分佈的影響，並調查了受試人員對各工況的主觀評價。
