Based on the simulated data produced by PROSAIL model and field test data, the authors respectively analyzed many kinds of factors which affect some representative inversion method s, such as VI, second derivative, model inversion and the directional second derivative.

以PROSAIL模型模拟数据和地面实测数据为基础，分别分析了土壤背景、冠层反射率非各向同性以及随机噪声等因素对几类代表性反演方法的影响(植被指数法、二阶微分法、模型反演法以及方向性二阶微分法)。

Eco-tour agriculture is to set up the agriculture on the basis of ecological environmental protection and development of the tourism resources, it is a great directional change in agricultural field.

开发区生态农业扩展区生态农业建设应以生态旅游农业为主要内容，生态旅游农业是建立在生态环境保护和旅游资源开发基础上的农业，是农业领域带有方向性的重大变革。

At present, the wireless devices in general to bring the whole antenna, omni-directional radio antenna to the antenna axis, was "donut"-shaped radiation field; directional antenna is highly directional, in the small angle of radiation is totally outside the scope of signals ; the use of removable external antenna equipment can gain antenna, the antenna can not increase in the case of radiated power to increase communication distance.

目前的无线设备一般自带全向天线，全向天线电波以天线为轴，呈"面包圈"状向外辐射；定向天线具有极强的方向性，在小角度的辐射范围外是完全没有信号的；使用可拆卸天线的设备可以外接增益天线，可以在不增加天线辐射功率的情况下增加通讯距离。

The next most important feature is directional control.

未来最重要的特点是方向性控制。
