earth radius
解釋
地球半徑-
The complex nonlinear pursuit - evasion model of two spacecraft in near - earth coplanar orbit is simplified to linear model, the circular region the radius of which is equal to capture radius is defined as target set, capture is achieved when the evader come into the target set and the game is over ; the boundary of useable part ( bup ) is determined, and the analytical form solution of the linear equations is obtained by backward integration of the state variables from the bup, the linear barrier of the pursuit - evasion model and the optimum thrust of the both sides are thus obtained
本文將近地共面軌道內運動的兩飛行器非線性追逃模型簡化為線性模型，以捕獲半徑的圓域定為目標集，確定目標集邊界上的可用部分，並以此為各狀態變量的起點，對時間進行倒向積分，求得線性方程組的解析解，從而確定了該追逃模型的線性界柵，以及界柵上對策雙方的最優推力，即求得了滿足最優策略時相對運動的軌跡和推力。 -

The numerical results indicate that the deformation within the solid inner core is very small. however, in the fluid outer core, the changes of the displacement with relatively low spherical harmonic degree ( n < 10 ) is very complicated via the radius, due to the resonance near the eigenfrequenies of the core long - period oscillations. while the spherical harmonic degree of the loading is larger than 10, the deformation and the gravitational perturbation in the core are very small, and the earth ' s deformation response is dominantly represented as the radial displacement in the elastic mantle
研究了地球在日月引潮力和表面負荷作用下的形變特徵，數值計算結果表明，在固體內核中的形變很小，由於在長周期核模本徵頻率附近的共振，液核中低階（ n 10 ）位移隨半徑的變化非常復雜，當負荷階數超過10時，地核中的形變和擾動位都很小，地球的響應主要表現為彈性地幔中的徑向位移，且隨深度增加急劇減弱，地表負荷love數與信號頻率的依賴關系很弱，給出了體潮love數計算的一種有效的近似處理方案。 -
For the construction of single - arch tunnel within cracked surrounding rocks, 8 tunnel models are set up to study the effect of the earth pressure distribution of the various surrounding rocks due to excavation. the relationships between the loosen zone of tunnel radial earth pressure and the tunnel diameter, the characteristics of surrounding rocks and the exposed time are revealed. it is showed that the pressure loosen radius is 1. 2 ~ 2. 0 tunnel diameters and the strongly loosen radius drops to 0. 5 ~ 1. 0 one for double lane tunnel

According to the sample prepared by hydrothermal method, the doping cations can enter the spinel lattice. rare earth cations mostly occupy position b because of their big radius. cerium are oxidized to ce4 +, whose radius is relatively small, and ce4 + mostly occupies position a. as a whole, the coercivity of cobalt ferrite doped with rare earth element is bigger than that of pure cobalt ferrite
結果表明，對水熱法制備的鐵氧體粒子，雜質離子能夠進入其尖晶石晶格中，並因稀土離子的半徑較大，而絕大部分佔據尖晶石的b位，鈰元素因被氧化成為四價離子，離子半徑相對較小，而主要佔據a位。 -
