The paper pointed out the conceptions of the space stability and the time stability for the foundation in the coal mining subsidence area and the four main points for the analysis on the foundation stability in the coal mining subsidence area.

Then,the time stability and other stability of permanent magnet materials were reviewed.

The temporal stability of soil water tension in an area of 32 km2(Pandian Village,PDV) and in an experimental field of 0.

These coherent states are of temporal stability,and can be regarded as the eigenstates of the lower operator with the eigenvalues in an operator field and as the rotational states of the generalized minimal uncertainly states as well.

Distribution characteristics of soil water and its temporal stability are important contents of soil water spatial variability and are considerably significant in further understanding spatial distribution in soil water.

Based on class K∞ functions,the more general definitions are proposed for kinds of finite-time stabilities,and the sufficient conditions are obtained by Lyapunov functions to ensure the finite-time stability of nonlinear systems.

Eight short corrected stories were used to test 281 Chinese children which were 3-9 years old from kinder-gartens and elementary schools for their understandings about the stability of traits,not only positive or negative traits but also stability across time or situations.

Using the classical temporal instability analysis method, the instability of an inviscid coaxial jet under a radial and an axial electric field, res.
