By constructing different quotient spaces,using the method of symplectic geometry,the self-adjoint extensions of symmetric differential operators in the direct sum spaces for the different deficiency indices at(2,2)singular points was discussed. The classification and description of complete Lagrangian submanifold that correspond with self-adjoint domains of second order differential operators were given.

由于对称微分算子在端点处的亏指数取值情况不同，当微分算子在端点处的亏指数均取(2， 2)时，通过构造商空间，应用辛几何的方法讨论了直和空间的对称微分算子的自共轭扩张问题，并给出了与二阶微分算子自共轭域相对应的完全Lagrangian子流型的分类与描述。

ResultsOne of 18 cases with drill drainage got cured in hospital, others were uncured when leaving hospital.

18例钻孔引流患者中有1例的硬膜下积液在住院期间治愈，其余盎者硬膜下积液出院时未见减少，其中15例1～6个月随访积液好转或自愈，2例演变为慢性硬膜下血肿；另24例行保守治疗的患者，其中21例1～6个月随访积液好转或自愈，1例演变为慢性硬膜下血肿，2例积液扩大有颅高压表现者行开颅剥除包膜并打通外侧裂池，术后6个月后随访痊愈。

For finding the best work function of SCC, SCC is requested to have favorable filling performance, rebar clearance passing performance and cohesiveness, and prevented from bleeding and segregation under the premise of assure that SCC"s flowing property due to by dint of rheology theory and analyse mechanism on concrete"s vibrationless moulding and compact.

为了得到自密实高性能混凝土的最佳工作性能，在研究中借助流变学理论，分析研究了混凝土拌合物免振捣成型和密实的机理，在保证自密实混凝土流动性的前提下，要求混凝土具有良好的填充性、钢筋间隙通过性和粘聚性，防止泌水、离析，解决了流动能力与抗离析能力的矛盾。
