Through field measurement for the contact pressure of box foundation with Ⅰ shaped plane of a high rise building on cobble subsoil, the distribution law of the contact pressure has been diagrammed. At the same time, the contact pressure has been calculated with finite compression layer model, which is well accordant with the measured result. The relative error of average value for the measured to the calculated contact pressure is 6.9%. This shows that the numerical calculation is right.

通过对西南交通大学某教学楼箱形基础基底反力的实测结果，得出了&Ⅰ&形平面箱基置于密实卵石层上的基底反力分布规律，又用有限压缩层地基模型对该箱基反力进行了计算，结果表明：实测反力与计算反力分布规律一致，实测反力平均值与计算反力平均值相对误差为6.9％，也说明此法计算箱基反力是可行的。

As a consequence, lower gabbros of the oceanic crust could have a larger crystal grain size on average than that of the upper gabbros as seen from the filed observations at the Oman ophiolite.

Love and the dear ones all are variables, when love decreases temperature, the dear ones are revaluing actually, if their mean value is higher than 50 throughout, then the marriage is stable, if their mean value is lower than 50, the marriage could be dangerous.

爱和瓜葛密切部门全部是可变物，当爱减少温度，瓜葛密切部门实际上再估价，要是她们的平均值50始终高于，之后婚姻是稳定的，要是她们的平均值低于50，婚姻能是危险的。

The method includes dividing a digital image, formed from M rows and N columns of pixels, into a plurality of band-shaped areas by partitioning at each of a prescribed number of rows; averaging, for each column, the gradation values of pixels in said band-shaped areas for each of said plurality of band-shaped areas; computing an approximation line which approximates, in each of said plurality of band-shaped areas, a distribution of said average of gradation values; and judging whether there exists a succession of d columns at which the difference between said gradation value derived from said approximation line and said average of gradation values for each column exceeds a prescribed threshold.

该方法包括：通过以规定行数为单位进行分割，将由M行N列个像素形成的数字图像划分为多个带状区域；对于所述多个带状区域的每一个，针对各列来对所述带状区域中的像素的浓淡值求平均；计算近似线，该近似线在所述多个带状区域的每一个中近似于所述浓淡值的平均值的分布；并且判断是否存在如下连续的d个列，在所述连续的d个列中，从所述近似线得到的所述浓淡值与针对各列的所述浓淡值的平均值之间的差值超出一指定阈值。

The results showed that under increasing field temperature in the period from male tetrad to maturing stage, the grain yield of ND108 and YD13 decreased by 46.6% and 45.1%, leaf area index decreased by 15.4% and 11.5%, and net photosynthetic rate of ear leaf decreased by 22.85% and 18.14%, respectively, compared with the control.

The modern rising rates of sea level in South China Sea resulting from observation of satellite altimeters and tide gauges, are up to 3.9 and 2.4 mm/a respectively, both slightly higher than the corresponding contemporaneous global mean rates.

而由卫星观测结果统计出的最近十几年以来南海海平面的上升速率达3.9 mm/a，略高于同期全球平均值；由验潮站统计出的南海海平面上升率为2.4 mm/a，同样略高于相应的全球平均值。

The experiments were carried out to calibrate FDR in the lab and field, and calibration equations were verified by oven-dried method for soil samples obtained by augers. The result showed that good calibrating equations with average RMSE 0.023 m^3/m^3 were fitted in the lab, but they had poor RMSE 0.066 m^3/m^3 when used in the field. Other calibrating equations with average RMSE 0.026 m^3/m^3 were also fitted by indirect field calibration method, and they had good RMSE 0.026 m^3/m^3 when used in the field.
