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.

Based on the study of K1 qn 1 source rock development and hydrocarbon-expulsion characteristics, overpressure and its distributing characteristicss, T2 source fault and its distributing characteristics of Fu-Yang oil layer in Sanzhao depression, the match of source rock, overpressure and fault and its controlling effects on hydrocarbon accumulation and distribution have been studied.

在综合研究三肇凹陷青一段源岩发育及排烃特征、超压及分布特征和T2源断裂及分布特征源岩、超压和断裂空间匹配关系对油成藏与分布控制作用的基础上：认为青一段源岩和其内超压空间匹配控制着三肇凹陷扶杨油层油成藏分布范围，超压和T2源断裂配置控制着扶杨油层油聚集深度和层位，超压和T2源断裂平面配置控制着扶杨油层油聚集的部位。

the way to drilling whole core at deep and thick layer is a difficulty in hydropower exploration. in present 10 years, by the sm plant glue drilling techniques, both the core adopt rate and drilling rate are improved. by the accumulation of practice experience and adjustment of technical parameter and confectmeasure, this drilling techniques get perfectly.

对深厚卵石层钻探完整取芯样问题一直是水电勘探中的一大难题，近十年来由于采取了sm植物胶金刚石钻进工艺，岩芯采取率和钻进效率都有一定的提高；随着实践经验的积累和技术参数、配制方法的不断调整，此钻进工艺得到了不断完善。

Experiments for controlling the soil matric potential of 0～-20 cm soil layer by use of irrigation and drainage have been conducted with lysimeters to study its effect on dry matter accumulation, nutrition and grain yield of winter wheat .

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.
