In contrast to the situation for a homogeneous isotropic neo-Hookean sphere, it is shown that not only there exists a secondary turning bifurcation point on the cavitated bifurcation solution which bifurcates locally to the left from trivial solution, and also the critical load is smaller than that for the material with no perturbations, as the parameters belong to some regions.

与均匀各向同性的neo-Hookean球体的情况相比，证明了当摄动参数属于某些区域时，从平凡解局部向左分岔的空穴分岔解上存在一个二次转向分岔点，空穴生成时的临界载荷会比无摄动的材料的临界载荷小。

Trivial Solution conception is put forwarded based on the theorem of K〓nig and forbidden node----for the n×n 0-1 degeneracy matrix, the solution under the condition that all element 1 can not be covered completely by n lines that must have intersects or can be covered completely by n lines that must have cross, without forbidden node, are called TS matrix.

本文在K〓nig定理和禁点定理的基础上，提出了平凡解的概念，即对于n×n阶的退化矩阵，全部1元素不可能被n条有交叉的直线全部覆盖或能用n条直线覆盖全部1元素，但无禁点的情况称为平凡解。并证明了如下的平凡解产生的充分必要条件：对退化矩阵A〓，若

This paper was concerned with the Dirichlet-Neumann mixed boundary value problem of bipolar quantum hydrodynamic model in thermal equilibrium. By truncation method and Leray-Schauder fixed point theorem, the existence of solution to the problem is proved. In addition, the uniqueness of the solution was proved as the Plank constant was large enough.

To resolve the imaging satellite scheduling problem with uncertainness, the demand for robust scheduling is analyzed, and a robust scheduling strategy of imaging satellites is proposed to devide the whole problem into two phases including the creation of robust solution and the dynamic adjustment of robust solution.

针对不确定条件下的成像卫星调度问题，分析了鲁棒性调度要求，提出了鲁棒性调度策略，将成像卫星调度分为鲁棒性调度方案生成和鲁棒性调度方案动态调整两个阶段。

Results:By chlorophyll disclosing solution coloring lymph nodes, we found, by injecting the solution into rectal wall of mouse, it colored lymph nodes quickly(in 30 minutes) and was not easy to precipitate. The dyeing lymph nodes showed emerald green, it contrasted sharply with surrounding tissues and no color fading after injected 24 hours. The average number of lymph nodes observed in each mouse was 6.92, which was more than that of LD1 group significantly(P.01). No adverse reaction or complication were observed in the course of injection and after injection, And the ultrastructure of the lymph nodes colored at different interval was no significant difference to the ones uncolored.
