According to by the time series estimate power spectral density\'s periodogram law principle,the research adopts five level of orbital power spectra which US Federal railway Administrative bureau FRA proposed;then,through the Fourier inverse transformation,the orbital not smooth time domain samples are obtained, which determine the track irregularity peak-to-peak value and the corresponding wave length; on the basis of the research,the influence of the wheel track dynamic contact force are considered.Based on the orbital roadbed coefficient\'s definition,computation model is established to solve the roadbed equispaced spring constant,and the roadbed uniform spring stiffness is obtained by using the numerical simulation method.Finally,based on the Matlab procedure platform,the computational procedure is established,and the load time interval caused by the moving train acts on the roadbed is obtained.

论文以解决陕北地区的收入问题，植被问题以及粮食产量问题为出发点，首先从理论上分析了包络分析方法在陕北地区退耕还林中运用的可行性，然后结合陕北地区目前的实际情况，综合分析出影响陕北地区退耕还林的关键的七个因素作为输入指标：水利水保设施投入，农作物投入，经济林种支出，防护林支出，其它经济作物，草类支出，畜牧业投入；以退耕还林所要解决的最终问题作为输出指标：GDP收入、农民人均纯收入、水土流失减少量、牧业总产值、粮食产量、林业总产值、其他经济作物总产值。将各指标所对应的数据代入模型后，通过分析求解得出非有效的决策单元，再运用包络分析方法的一些基本原理对非有效的决策单元进行调整，由此所得的数据对陕北地区的实际投入具有很好的指导意义。同时，又针对陕北地区在退耕还林过程中以及之后可能面临的困境，提出了一些建议和对策。最终使得陕北地区的投资环境尽快得以改善，使农民尽快脱贫致富，使人口、资源、环境的关系尽快纳入良性循环的轨道上。

Additionally, we analyzed the thermal-decay rules of LPGs. We use temperature-compensating package to reduce the sensitivity of temperature of LPGs. At the end of this paper, we summarized the key technologies required during practical application of LPGs, During this paper, we obtained some inventional results as follow: 1. We deduced waveguide modes of single and many mode fibers by use of Maxwell equation.

论文工作期间，主要取得了以下几方面的成果：一、我们利用Maxwell方程，推导了单模和多模光纤的导波模式，同时利用耦合模原理，简要推导了反射式光纤光栅的模式场分布及相应的模式特征方程；采用弱导光纤近似理论，严格推导了透射式长周期光纤光栅的模式场分布，得到了光栅周期与光波长间的对应关系，这是分析长周期光纤光栅光谱特性的有力工具。

Facing the empirical facts of natural objects, I believe that an inevitable remedial opinion can be concluded for 'relativity principle' of mechanics: the law that governs the changes of the motion of objects in inertial system corresponds to which of the two mutually uniformly rectilinearly moving reference systems is used to describe 'the changes of location' of these movements.

面对自然客体的经验事实我认为可以得出对力学&相对性原理&的一个必然的修补意见：惯性系物体运动据以变化的定律，同描述这些运动&位置的改变&的参考系究竟是用两个互相匀速直线移动着的哪一个参考系相对应。

The former reflects reciprocity (parallelism, parity or immediacy oneness) of rights and obligations, and the latter reflects non-reciprocity (imbalance or unimmediate oneness) of rights and obligations.

前者表现为权利和义务关系的对等性（或对应性、同位性或直接统一性），后者则体现为权利和义务关系的非对等性，两者构成了权利和义务关系原理的基本方面。
