rest density 中文意思是什麼
rest density
解釋
靜止密度-
In order to make the theoretical calculation feasible, we first obtain an analytical formalism of partial integrals with respect to the coordinates of the core and target in the phase - shift functions and their cross terms of scattering matrix elements, if the density distributions of the core and target are fitted to a few gaussian forms. then the rest multidimensional integrals with respect to the impact parameter and coordinates of halo nucleons are performed by a monte carlo method
為使理論計算變得可行，我們在核芯和靶核密度採用多個高斯分佈擬合的情況下，解析求解了各個散射矩陣元中的光學相移函數及交叉項含有的與暈核核芯、靶核密度分佈有關的積分;同時對與碰撞參數和暈核子坐標有關的積分（八重以上，並且積分維數隨暈核子數很快增加）採用蒙特卡洛方法計算。 -
The fractional change in bold signal for a given change in blood flow can vary in different parts of the brain, depending on the local density of blood vessels and the physiological state of the particular tissues at rest
同樣的血流改變所導致的血氧濃度變化信號變化，在腦的不同部位會有不同的大小，端視局部的血管密度以及靜態下特定組織的生理狀態而定。
