On the basis of sensitivity analyses using the PROSAIL model, the present study demonstrates an approach that uses a neural network based on image classification incorporated in PROSAIL for accurate retrieval of LAI. By including the soil reflectance index in the original PROSAIL model to take the place of soil background reflectance parameters that are difficult to determine, specific neural networks are constructed corresponding to individual types of vegetation cover.

在PROSAIL模型敏感性分析的基础上提出了一种基于影像分类的神经网络反演方法，引进了土壤反射指数用于替代原模型中难以确定的土壤背景反射参数，分别针对不同植被类型建立各自的神经网络，对经过大气纠正后的Landsat ETM+影像进行了模拟实验并同野外实测LAI数据进行比较。

And not just in the wilderness either. One day I was watching the swallows flying back and forth to their nests under our eaves here in Beijing when I suddenly noticed they had red patches between their tails. I immediately looked them up in my bird book and discovered they were red-rumped swallows, a species I had never seen before.

The average activity of carboxylesterase of the field flies were higher than that of houseflies of the relatively sensitive strain in the laboratory. The distribution of carboxylesterase activity in both sensitive and field populations were obviously overlapped.

从CarE平均比活力看，室外家蝇种群CarE的比活力均高于室内相对敏感种群的比活力，CarE活性的分布在敏感种群和不同地区野外种群间具有明显的重叠现象。

The principle of railroad trackbed inspection with GPR mounted on track vehicle is introduced. In line with requirements of exploring depth, accuracy and speed in the process of field survey, the layout of GPR survey line is put forward, the center frequency of antenna, the maximum time window, the temporal sampling interval and the space between traces are calculated according to the theoretical formulas.
