Since the solutions of this problem are the critical points of the associated energy function. One generally needs some compactness such as PScondition or C-condition to prove the existence of critical points of the energy func-tion, but when we study the elliptic equation in R~N, the compactness condition does not always hold since the imbedding of the Sobolev space H_0~(1,2)into L~(2*) is not compact. In this chapter, based on the nonsmooth critical point theory, and by using the approximation technique with periodic function, the existence of nontrivial solution is obtained.

由于该方程的解就是其所对应的能量泛函的临界点，通常都要在一些紧型条件的基础上来证明其所对应的能量泛函临界点的存在性，但当我们在无界域上考虑该椭圆方程解的存在性时，Sobolev空间H_0~(1，2)到L~(2*)的嵌入非紧，从而导致所对应的能量泛函失去紧性，本章在非光滑临界点理论的基础上，应用周期逼近的方法证明该问题非平凡解的存在性。

Firstly, the soil samples are gathered from the same section such as surface layer soil samples gathered from 0cm to 15cm depth and representation on studied object. Secondly, the precondition of tested samples must be the same. This study indicates that the tested samples must be 1mm diameter, over-dried at 40℃ for 24h and airtight cooling for 24h before measured for air-dry samples, and softly planish the surface at measuring. Lastly, the illuminating condition of light must be the same. This study indicates that the testing geometric condition are light source angle 15°, light source distance 30cm and sensor distance 15cm for soil hyperspectra indoor. The surface of white reference must be the same plane of that of sample.

第一个环节的"相同"是指田间土壤样品采集时的剖面位置一致，如表层土都采集0～15cm深度范围内的土壤，且所采集的样品应能尽量具备研究对象的代表性；第二个环节的"相同"是指土壤制备过程中的一些前处理条件应一致，建议土壤光谱测试样品的粒径1mm，风干土壤样品测试前在40℃恒温条件下烘24小时，然后密闭冷却24小时，测试时土壤表面进行稍稍压平处理；第三个环节的"相同"是保证测试光照条件的一致性，建议在50W卤素灯、8°探头角条件下，采用15°的光源照角度、30cm的光源距离和15cm作为室内士壤高光谱测试几何条件，测试时除遵循光谱测试指南的要求外，还须保证参考板表面与测试土壤样品的表面在同一平面上。
