不规律

Taking the 1#'s coal trestle in the coal-smashed engine room of Shenyang thermal power plant which was set up in 1958 for example, it is discussed that when fall-off height of concrete in drawing district of reinforced concrete structural member harmed seriously in flexure increase, the bond performance of reinforcing bar and concrete deteriorate continuously and the time-dependent regulation of the weight force and deformation of structural member. Dynamic reliability indexes before and after consolidation is obtained by the method.

Larches of different ages have different net photosynthetic rate: the photosynthetic capacity of the young ones are bigger than that of the old ones; the stand density do not affect the net photosynthetic rate obviously; as far as the different stand classes are concerned, the diurnal changes of net photosynthetic rate is closely related to the photosynthetic active radiation. For the different layers of the crowns, there are greater ecological factors (illumination intensity, temperature, humidity etc.) on the upper layers than on the lower layers: the CO2 concentration of the lower layers is greater than that of the upper layers, which is indeed an exception; the net photosynthetic rate on the upper layers of the crown is generally greater than that of the lower layers. It showed that the CO2 concentration is not a main factor in the natural changing range of the CO2 concentration. Different directions of the crown have different photosynthetic active radiation, which is generally like exposed to the sun﹥North﹥in the shade of crown. However, the changes of net photosynthetic rate are not quite the same, which is North﹥exposed to the sun﹥in the shade of crown.

不同年龄的兴安落叶松净光合速率不同，年龄小的个体光合能力高于年龄大的个体；群团密度与净光合速率没有显著的相关关系；而对不同分级木，净光合速率日进程变化规律与光合有效辐射有着密切的联系；林内树冠不同层次各生态因子有上层大于下层的趋势，而CO2浓度在下层的含量高于上层，净光合速率上层普遍大于下层，说明在林内自然CO2浓度变幅内，CO2浓度不是主要因子；兴安落叶松树冠不同方向的光合有效辐射不同，一般向阳﹥北向﹥背阴，而净光合速率变化有北向﹥向阳﹥背阴的趋势。

研究结果表明：用相对流量系数（转动时的流量系数与静止时的流量系数的比值）与速比（周向速度与轴向通流速度的比值）的函数关系表征泄漏量随转速变化的规律时，存在一个临界速比约等于1.0；低于这个临界速比时，转速对泄漏量的影响不明显；高于这个临界速比时，泄漏量随转速的增大而减小，在很高的转速下（6000r/min以上），泄漏量至少减小了5.1%；相同间隙下，泄漏系数随着压比的提高而近似线性增加；相同转速下，随着密封间隙的减小，相对泄漏量逐渐降低。

Using maximum flooding surface and local explosure erosion surface as the correlation framework surface in the 4-th hierarchical base-level cycles, sand-body in the 3-th hierarchical base-level cycles formed in the 4-th hierarchical base-level cycles may be correlated layer by layer. The law of the sand-body and the characters of reservoir heterogeneity formed in the 4-th hierarchical base-level cycles are discussed. The study shows:①During early period of the 4-th hierarchical base-level cycle rising, subaqueous distributary channel formed, continuously stacked vertically, and migrated in limit range laterally, and channel sand-body stretches farther longitudinally, and lacks interbeds of mud rock and siltsand in sand rock, reservoir heterogeneity is relatively weak.②During mid-period of the 4-th hierarchical base-level cycle rising, subsaqueous distributary channel migrated actively, channel divided and converged strongly to form netted sand-body and sand sheet mainly, but interbeds of mud rock and siltsand increases gradually in sand-body, reservoir heterogeneity increased.③During later period of the 4-th hierarchical base-level rising and early period of the 4-th hierarchical base-level falling, reservoir sand-body was poor, and only form thin sand-body of subsaqueous distributary channel, subsaqeuous creveas and distal mouth bar, sand-bodys are surrounded by mud and silt rock.
