水淹

The results showed that flooding significantly increased the content of amorphous iron oxides and P adsorption capacity accompanying with a sharp decrease of crystalline iron oxides and P desorption in two tested soils.

结果表明，淹水使土壤中结晶态氧化铁含量明显减少，无定形氧化铁和土壤对磷的吸附量急剧增加，磷解吸下降；落干则使之发生相反的变化。

In the pot test, with the hybrid mid-rice Liangyoupeijiu as material,4 soil water potential (flooding, 0,-30 and 60 kPa) and 5 nitrogen levels (0, 1.5, 2, 2.5 and 3.0 g/pot) were set up to study the effects of water and fertilizer coupling on growth characters and yield of rice.

方法］在盆栽试验中，以杂交中稻两优培九为材料，设4种土壤水势（淹水、0、-30和-60 kPa）和5种氮肥水平（0、1.5、2、2.5和3.0 g/盆），研究水肥耦合对水稻生长性状及产量的影响。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
