Therefore, we selected common species of Ranunculaceae. comparative primordial plants in Alpine Meadow at Eastern QinghaiTibetan Plateau, and studied the reproductive strategies, such as reproductive allocation, especially sex allocation, to understand how the plants adapt the environmental conditions. The results showed:(1) At higher altitude, the self-incompatible plant, such as Trollius ranunculoides tended to become limited by pollination rather than by nutrient availability, while the self-compatible plants, such as Anemone rivularis and A. obtusiloba seemed not to be limited by pollen availability, which suggested that ability of self pollination for alpine plants may be a mechanism of reproductive assurance.(2) Influences induced by high altitude on the reproduction of these species occurred on different reproductive characters, which suggest species-specific adaptive strategies. The influences are dependent on plant size to some extent.
因此,我们选择在青藏高原东部的高寒草甸,以比较原始的植物类群—毛茛科植物为研究对象,选择一些常见种探讨其繁殖对策,如繁殖分配和性分配问题,试图揭示这些植物如何适应环境条件,最后的结果表明: 1高寒草甸高海拔区,自交植物(如小花草玉梅A.rivularis和钝裂银莲花A.obtusiloba)的繁殖不受花粉限制,而完全异交植物(毛茛状金莲花T.ranunculoides)的繁殖受花粉限制,表明高海拔地区植物的白花授粉能力可能是一种繁殖保障机制,能够避免恶劣环境对植物有性繁殖的不利影响; 2海拔高度对植物的影响因种而异,不同的物种受影响的繁殖性状不同,即使同属亲缘种间也存在差异,表明不同物种对相似环境压力的适应对策不同;而且,海拔高度对植物的影响在一定程度上依赖于植物个体大小,说明植物通过调整其个体大小与繁殖性状的关系来适应环境梯度的变化; 3植物花期和果期的繁殖分配并不完全随海拔升高而减小(只有小花草玉梅的果期RA随海拔升高而减小30%),与Iwasa和Cohen的预测不完全一致(他们认为繁殖分配随生长季缩短而减小)。

In actual reactors, the cooling condition outside the hexcan-wall of blocked fuel subassembly is analogous to its counterparts in the SCARABEE BE+ experiments. The upward and downward heat transfer could be neglected, while the radial heat transfer plays a key role in slowdown the accident scenario. As time goes on, the dominant radial heat transfer mechanism is liquidus sodium convection at first, and then gradually transforms into sodium condensation near the inner surface of the hexcan-wall, and finally becomes volume heated boiling pool convection.
对实际快堆中发生全堵的燃料组件而言,其外部的冷却条件与SCARABEE BE+系列实验非常相似;2)堵流组件向上和向下的传热可忽略不计,径向传热对事故有较强的延缓作用;3)随着时间推进,径向传热的主导机理依次为液态钠单相对流、钠蒸汽在组件盒内壁冷凝、体热源沸腾池散热。

This paper compared two kinds of rose families sorbus of different effective spots of total flavonids content. We get a better process of total flavonoids abstraction from the branch of Sorbus tianschanica,.Under the best process of total flavnoids ,two flavnoids were isolated from them. Preliminary affirmed two kinds of compounds belong to flavanone, two kinds of structure just substituent had a dissimilarity separately. This thesis was a part of a national natural science fund to subsidize.

However, today in the legal service industry, there are some conditions that can not be ignored: various subjects supervised by different public sectors,with different entry requirements and professional conduct ,at different cost,provide with the same or similar services in a market .That lead to the disorderly competition, lack and dislocation of the government supervision ,the uneven distribution of legal services resources and the growing tendency of commercial issues and uncredibility on the legel service market. That seriously influnce the healthy development of the legal service market,affect the values of the legal services fuctions and fulfill pushing on the rule of law,improvement of the socialist market economic system and building a socialist harmonious society with great efforts.
但是,法律服务业发展到今天,出现了一些不容忽视的状况:多个法律服务主体以不同的准入条件、不同的执业规范、不同的服务成本在同一个市场上提供相同或相似的服务,受到不同部门的监管,导致多个主体无序竞争、政府监管缺位错位情况突出、法律服务主体资源地区分布不平衡、法律服务业诚信缺失、商业化倾向日趋严重等问题,严重影响了法律服务市场的健康发展,难以有效实现法律服务的价值功能,难以适应依法治国、完善社会主义市场经济体制和构建社会主义和谐社会的需要。

The controlling effect of tectonics to evolution of microcracks is analyzed by using the damage mechanics theory. These characteristics can be analogized to kilometer meters as the first effect of earthquake precursors. These studies may be helpful to interpret the foreshock or general foreshock in the moderate or short stage before strong earthquakes.
