Very little has been published on the optimum flow rate for particular materials and even if this were known the relationship between optimum flow rate and gate width would probably be complex because of the large number of variables involved.

在特定材料的流动速率优化方面，已经发表的文献很少，并且即使已知优化流动速率和浇口宽度之间的关系，也会由于包含很多变量而使得情况变得复杂。

With the increase of the flux change velocity of the flow passing the gate, the overflowing phenomenon occurred earlier, and the rise of water level in front of the gate during its closing period was of a linear relationship with the flux change velocity of the flow passing the gate.

闸下出流量的变化速率越快，出现漫溢的时间也越短，闸门关闭期间的闸前水位上涨速度与闸下出流量的变化速率呈线性变化关系。

The variation of freezing rate and thawing rate in the process of repeatedly freezing and thawing explained by the variation of the thermal conductivity.

利用导热系数在冻融过程中的变化解释冻结速率和融化速率在冻融过程中的变化。

Based on the mechanism of gas diffusion,factors that influence gas diffusion in concrete are analysed.

混凝土碳化速度与钢筋锈蚀速率主要取决于气体在混凝土中的传输速率。

One of the main reasons is the influence of hydrogen bonds, such as glycollic and benezene and alkanones, and benezene volatile rate is 2 times the ethanol, butanol alkanones than n-butyl acetate low and volatile rate is also low, from here discernthat chemonucleolysis dosage form hydrogen bonds to limit business card printing and membership card making ink ink film volatile plays an important role to play.

主要原因之一是氢键的影响，如乙醇和苯的沸点接近，而苯的挥发速率为乙醇的2 倍，丁醇的沸点比醋酸正丁酯低，而挥发速率也低，从这里看出氢键对限制溶解剂型制卡和会员卡制作油墨的墨膜挥发起着重要的作用。

According to the 137Cs concentration distribution along a typical profile A-1, the sediment accumulation rate and the natural surface soil erosion rate are respectively 16.6t/km^2a and 45.95t/km^2a, which shows that about 63.88% of the eroded surface soil is removed by way of underground loss. The relative contribution ratio of surface soil loss and underground soil loss are respectively 70.13% and 29.87%. By comparison to the utmost soil formation rate 13.51t/km^2a in Maolan, the risk of soil erosion in the Engineering Monument grass-covered depression is higher.

2根据草地洼地典型堆积农耕地土壤剖面A-1的137Cs浓度分布特征，1963年以来的流域平均堆积泥沙数量是16.6t/km^2a，流域平均土壤侵蚀速率为45.95t/km^2a，约占侵蚀产沙数量63.88%的泥沙以地下流失的形式散失；(3)草地洼地小流域内地面土壤流失与地下土壤流失的相对贡献率分别是70.13%和29.87%；(4)以茂兰地区最大成土速率为依据推算出的允许土壤侵蚀量是13.51t/km^2a，草地洼地的土壤侵蚀危险程度极高。
