The entanglement of formation and the Peres condition have good correspondence, and if the mixed-state deviates the similar pure state slightly, its maximum entanglement drops suddenly. The conclusion of the entanglement of the infinite dimension mixed-state in J-C model never losing is demonstrated besides finding the necessary condition of disentanglement of the finite dimension mixed-state in J-C model.

通过研究有限维混合态光场与二能级原子相互作用系统中的纠缠，发现形成纠缠理论与Peres判据有着良好的对应，同时看到偏离纯态很小的混合态，其最大纠缠度急剧减小；找到了有限维混合态J-C模型在演化过程中出现消纠缠的必要条件，论证了在无限维情况总存在纠缠的结论。

In this paper, the marshland of Daxinganling forest region is classified into three kinds, the pass performance of three kings of crawler fire engine, J-50, A531, BFC804 and a kind of two-wheeled forest fire engine of special light-duty HS-8 is studied in theory and test, the calculation formulas of the tangential traction force and the external motion resistance of vehicle are given and the drawbar pull is used as evaluation index.

对大兴安岭林区的沼泽地进行了分类，并对3种履带式森林消防车J-50、A531、BFC804和一种特轻型双轮森林消防车HS-8的沼泽地通过性作了理论与试验研究，给出了切线牵引力和行驶阻力的计算公式，采用挂钩牵引力作通过性评价指标。结果表明，BFC804可以通过重沼泽地，A531和HS-8可以通过中沼泽地，而J-50只能通过轻沼泽地。

Firstly,by using the estimating methodfor the compact embedding operators(from weighted Sobolev space to the weighted〓space),we obtain a necessary and sufficient condition for the discreteness of thespectrum of certain differential operators.Secondly,based on the property of thespectrum of difinitizable operators on the Krein space,we consider the left definitedifferential equations with middle deficiency indices,and give a completecharacterization for self-adjoint(J-self-adjoint)differential operators in theindefinite inner product space 〓.Especially,we prove that all the J-self-adjoint differential operators are definitizable.
