Firstly, we give out the definitions of L-graph and partial L-subgraph, and we ob-tain some properties of partial L-subgraphs. Secondly, continuous mapping is intro-duced respectively between L-graphs and between L-cotowers, and the relationshipbetween the category L-FG of L-graphs and the category FG_L~C of L-cotowers isstudied. At last, we study the finite topological property of the category L-FG, andgive out the concrete constructions of finite product and finite coproduct.

本章首先给出了L-图和部分L-子图的概念，得到了部分L-子图的若干性质；其次，给出了L-余塔的概念，在L-图之间和L-余塔之间分别引入连续映射，研究了L-图范畴L-FG和L-余塔范畴FG_L~G之间的联系；最后，研究了L-图范畴L-FG的有限拓扑性质，给出了L-图范畴L-FG的有限积和有限余积的具体构造。

The maximum principle of the optimal control for the stochastic systems described by Zakaj stochastic partial sifferential equationis proved by approximately minimum point theorem of E. Ekeland. The convexity and compactness of the set of control values is not assumed, and it is not necessary for the maximum principle about differentiability in control variables included in drift term of the stoch astic system and the integrand in index functional, and costate process satisfies the stochastic partial ...

在不假便定控制变量取值的集合是凸的和紧的，不要求随机系统的漂移项和指标泛函的被积函数关于控制变量具有可微性的情况下，用E，Ekeland的近似极小点定理证明了Zakai随机偏微分方程描述的随机系统的最优控制的最大值原理，和用很简洁的方法证明了协态过程满足一个随机偏微分方程。

The lack of consistent high Poisson′s ratio (≥0.30) shows that widespread partial melt does not exist within the curst, but does not exclude the presence of local partial melt.③There is an obvious thickened zone of the mantle transition zone compared with IASP91 standard value which varies from 10 km to 26 km in Qiangtang terrane. The anomaly suggests that the temperature is about 100 ℃ to 260℃ lower than global average value within the mantle transition zone, and it may be attributed to the presence of a subducted slab within the mantle transition zone.

缺乏高的泊松比(≥0.30)分布表明青藏高原东南缘的地壳不存在广泛的部分熔融，但是不排除局部部分熔融的存在；③青藏高原东南缘的羌塘地体内存在一个比较明显的、异常变化范围为10～26 km的地幔过渡带增厚区域，其对应着地幔过渡带内100℃～260℃的温度降低，可以推断与此异常区域的地幔过渡带内存在俯冲的板块有关。
