查询词典 volume integral

Path analysis of nine traits, which were highly correlated with tree volume, showed that the direct contribution of DBH and height on the variations of tree volume took up about 63% of the total variations. On the other hand, those traits, such as tree crown and wall/lumina, affected the volume strongly by indirect way of the genetic correlation with DBH and height.

通过对与材积性状紧密相关的胸径等9个性状的通径分析发现，胸径和树高两个性状对单木材积的直接作用占材积总变异的63％，其余性状的直接控制作用很小；冠幅、壁腔比等性状通过胸径对单木材积具有很大的间接遗传控制作用，这种控制是通过与胸径、树高的遗传相关实现的。

Weigh's addition minishes the loss of net's volume in pure current, but makes no differnce in the pure wave condition. After installed of sinking ring or lower ring, the loss of net's volume is decreased. The loss of net volume is more in the current combined with wave condition than in the pure current condition.

在纯流条件下，增大配重均有利于减小网箱的体积损失；而在纯波条件下，配重的增加对于改善网衣的变形没有实质性的意义；设置了底圈或沉降圈后，均能在一定程度上减小网衣的体积损失；波流组合条件下网衣的体积损失要明显大于纯流条件下的体积损失。

The different points of views, transverse section, plane and volume changes are considered. The results show that the evolution of the Xinqiao Channel has experienced three stages: in 1861~1926 ,the Xinqiao Channel area had been eroded at first and then silted; the Xinqiao Channel is formed during 1926~1958 with the channel experiencing persistence erosion; from 1958 to 2002, the total volume of the Xinqiao Channel keeps stable with the volume of 5.02×108m^3. The pattern of 10m contour has shaped to a certainty in 1926 and 5m contour of the upper and lower parts of Biandansha has been joined. The change of sections of the Xinqiao Channel reflects its thalweg movement to the North Bank 1.1~2.8 km, its shape changes from "U" shape to "V" shape and its depth has been deepened.

计算结果显示在所研究的区域内自1861年以来新桥水道冲淤过程明显被分为三个阶段：1861~1926年的66a间新桥水道区域经过一段时间的冲刷后又重新产生淤积，总容积变化不大；1926~1958年的33a间新桥水道在不断的冲刷中总容积由2.603亿立方公尺增长到5.076亿立方公尺；1958年至今的45a时间里水道容积基本保持在平均5.02亿立方公尺。1926年新桥水道10m等深线已经形成一定的格局，1947年5m等深线向上延伸，扁担沙已经不再与崇明岛相连；1958年上下扁担沙的5m等深线基本连成一体，可以认为此时新桥水道已经形成。

Bellows Gate Valves However, in large differential pressure operating conditions, evaporation pressure has eased, the evaporator load requirements of the fluid volume decreased, but the actual situation the contrary, in the suction superheat unchanged, due to evaporation pressure has eased, the evaporator outlet pressure be reduced accordingly, pressure changes above and below the diaphragm, causing the main valve opening increases for increased fluid; but in a small pressure operating conditions, evaporation pressure rise, evaporator load demand for fluid volume increased, but the reality is that in the suction gas superheat unchanged, due to evaporation pressure rise, a corresponding increase in the evaporator outlet pressure, pressure difference above and below the diaphragm smaller, so that the main valve opening decreased for the reduction of liquid volume; in variable load is all about.

但在大压差工况下，蒸发压力降低，蒸发器负荷需求的液量减少，但实际情况相反，在吸气过热度不变的情况下，由于蒸发压力降低，蒸发器出口压力相应降低，膜片上下的压差变大，使主阀开度增大，供液量增加；但在小压差工况下，蒸发压力上升，蒸发器负荷需求的液量增多，但实际情况是在吸气过热度不变的情况下，由于蒸发压力上升，蒸发器出口压力相应提高，膜片上下的压差变小，使主阀开度减小，供液量减少；在变负荷下亦如此。
