查询词典 accumulation layer

It has been found that wear of the claddings is characterized by plastic deformation and local accumulation in the subsurface region at the early sliding stage. Then cracks were generated in the borders of different phases and grains. The cracks tended to extend, grow, and finally detach from the surface layer of the cladding, with the formation of wear debris.

研究结果表明，小麦抽穗初期、乳熟期和完熟期的干物质累积均在土壤基质吸力30～40kPa下最多，小麦地上部对氮，钾的吸收量以及籽粒产量在土壤基质吸力30～40kPa下最高。

The results show that the condensation of moisture is easily occurred in the insulation layer far away from the steel-framed component and its moisture accumulation is also more than that of other places.

结果表明：远离龙骨处的保温层冷侧更易结露，且该处的保温层采暖期重量湿度增量值较龙骨附近的大。

When the plant N level was below 2%, the leaf starch accumulation kept stable, but the sugar content in leaf and starch content in lower layer leaf increased. When the plant N level was between 2. 0% and 2. 8%, the activity of SPS and leaf soluble sugar content were the greatest, which was favorable to the transportation of the accumulated matter from the leaf to the grain.

随植株氮水平提高，叶绿素总含量提高，但叶绿素b的提高速度快于叶绿素a；当植株叶片含氮率在2％以下时，随植株氮水平提高，水稻叶片淀粉积累不仅没有减少，相反叶片中的糖含量和下层叶的淀粉含量还有显著提高；当植株叶片含氮率在2.0％到2.8％的适宜水平时，叶片SPS酶活力和可溶性糖含量最高，有利于叶片中积累物质向籽粒转运。

I. e δ^13C and δ^18O ratioes obviously vary with height, generally, the heavier/lighter isotope ratio is higher at the upper/bottom layer of canopy; and temporally,δ^13C and δ^18O ratioes are highest from afternoon to sunset, and lower before dawn, with the lowest ratio at the time when air is stable and the CO2 from the respiration of vegetation and soil reaches the biggest accumulation amount.

主要表现在δ^13C和δ^18O在冠层内具有明显的垂直变化趋势，冠层上部重同位素含量较高，而底部含量较低。从时间变化看，δ^13C和δ^18O在午后到日落具有较高的水平，而凌晨，δ^13C和δ^18O较低。
