unstable solution
解釋
不穩定解-
The unstable solid solution would disintegrate and transform into carbide phases in these systems of sisocso, tisocso and zrsocso, based on the increase of free energy introduced by the effect mechanical alloying. for the system of wsocso, the solid solution had not transformed into tungsten carbides but an amorphous phase, which was different from those systems. the exist of fe in these experiments, which came from the abrasion of ball - milling tool because of the higher hardness of w and w - c solid solution, would induce the crystalline - to - amorphous phase transformation during milling

Through such a study, it is also shown that when the time delay is long enough such that the stability switches of the equilibrium of system halt, the bifurcation branches originated from the critical time delays cannot be surely stable or unstable in the whole solution space, that is, their stability depends on cases. this phenomenon also implies that the stability of the periodic solutions on the bifurcation diagrams indicates only the stability on the local center manifo ld. some distinguished features of delay dyn
利用打靶法的數值結果說明了當系統平衡點不再發生穩定性切換時，源自這些臨界時滯處的解支的穩定性在整個解空間的穩定性具有不可判定性，這也說明由多尺度法所得高階近似判定的解支的穩定性事實上只表示解支在局部中心流形上的穩定性，而非在整個解空間中的穩定性。 -
