This study was conducted in Taiyuan sewage irrigation area from 1997 to 2000.The research process included field investigation, sampling, lab test, model experiment and data analysis by geo-statistics method. The source, affecting factors, content condition, transference regularity, spatial distribution of heavy metal in sewage irrigation area were studied. The results showed that mercury, cadmium and lead contents of soil were higher than soil background value.

Using environmental radionuclide 210Pb to study the soil erosion and sediment had great application value and potential. When the nuclide was settled on the surface with atmosphere, it was absorbed by the soil particle quickly. The soil erosion rate on the scale of 100 years was traced through the remotion of nuclide in soil and its regular distribution nude.

Initially the following measures are taken for association of the angle positions to physical reflectors, and for determination of the position of the vehicle (10): i at least three angle values with a suitable distribution over the search sector is selected, ii the angle values are associated to reflectors and a position is determined for the vehicle on the basis of the known position of the assumed reflectors, iii if the vehicle position determined in this way is within a certain part of the transport area the other angle values are associated to reflectors, iv for each angle value, existing deviation is determined between detected angle values and angle values expected between the vehicle position and known reflectors, v the measures taken are repeated for each possible combination of selected angle values.

最初使用下列步骤使这些角位与反射器关联以便确定车辆（10）的位置：i）在该搜索扇形上选择至少三个合适分布的角度值，ii）使各角度值与各反射器关联，根据假设反射器的已知位置确定车辆的位置，iii）如果如此确定的车辆位置在该运输区的某一部分中，则使其他角度值与反射器关联，iv）对于每一角度值，确定所检测角度值与车辆位置与己知反射器之间预期角度值之间的偏差，v）对于所选择的角度值的每一种可能组合反复进行这些步骤。
