The application of "anchoring and shotcreting" supporting technology in the bunker construction is introduced,"anchoring and shotcreting"is a kind of timbering fashion of safety,especially in surrounding wall rock on bad conditions.

Besides mechanics calculation,demonstrates the device is safe and reliable,with a good result in application and worth popularization.

Communication power system safe and reliable to run at first choosing best to dispose from design, science is rational, reserve the development space.

To guarante its function perfect,the flow optimization,safe and reliable,speeded up the advancement was the important topic of the current construction for Integrated Management Information System of Stations.

B(F)=I_n and E iscompletely integrable at z_0 iff A(F)=(A(F))~l; if z_0∈∑π is a contact regular point,then F can be chosen s.

A new completely integrable finite-dimensional Hamiltonian system is obtained by nonlinearization of the eigenvalue problem.

We say that an element Z∈Ais an all-derivable point of A for the strongly operator topology if,every strongly operator topology continuous derivable linear mapping φ at Z is a derivation.

(c) Let V≠0 be a faithful and completely reducibleF[G]-module over an arbitrary field F.

completely reducible,quasi-primitive and finite G-module for a solvable group G.
