On the basis of the conclusion above, the nonlinear weak controllable vectors can be obtained, which compose the second class of weak controllable matrix, by means of matrix transfermations of the first class of weak controllable matrix. Furthmore the second criterion of weak controllability, accessibility and strong accessibility, which is more standard, more succinct and more practical, is obtained. On the basis of the first criterion and the second criterion, several important problems about nonlinear controllability are discussed, which include 1 local controllability; 2 three classes of local controllable decomposition, separately by means of local coordinate changes in the neighborhood of a nonsingular point, a point on a singular surface or a designated point x〓 with a designated input u〓; 3 the character of controllability of the ith state variable x〓 in different controllable areas and their boundaries.

The principle of work is: When ambient temperature rises, the pressure of the SF6 gas increases, drives the indicator along the clockwise rotation, but at the same time, the mouth of the bimetal compensation system "the U shape" publicizes, then impels the indicator to the counter clockwise rotation, when two kind of strength be equilibrium, the ambient temperature change cannot made the indicator deflection.
