查询词典 accumulation

To check the abilities of Zn uptake and accumulation of duckweed (Lemna minor Linn.), experiments of growth, Zn accumulation and SOD activitial response to Zn in plant duckweed were performed with fresh plant in vivo. The results showed that growth of duckweed was affected by 5 mg/L Zn treatmenat in solution, indicating better resistance to Zn.

试验底栖甲壳类远海梭子蟹则主要富集淤泥中的Zn、Pb和油类，其累积率分别为40%、100%和205%，对Cu、Cd和Hg累积效应不明显。关键词：淤泥；毒性；海洋底栖动物；累积率

Based on time-course observations on the nitrogen accumulation, assignment, absorption and remobilization under various nitrogen rate regimes with different cultivars, a dynamic model was developed to simulate the nitrogen accumulation and assignment before anthesis and the nitrogen absorption and remobilization model after anthesis in barley.

通过定量分析不同品种和氮肥处理大麦氮素吸收、积累、分配和转移的变化过程，建立了大麦花前氮素积累及分配和花后氮素吸收转移动态模型。

The critical nitrogen content in heading period was used to calculate the biggest accumulation quantity of nitrogen. The latent distribution index of leaf and stem, which was the variety heredity parameter, were used to distinguish the difference in nitrogen assignment in different varieties. The dynamic content of the nitrogen accumulation before anthesis could be described with a Richards model. The dynamic content of the nitrogen remobilization in leaf with leaf area index could be described with a power model, and the nitrogen absorption of grain from soil with dry weight could be described with a power model. The dynamic content of nitrogen density in stem and spike with physiological development time could be described with a nonlinear model.

模型利用抽穗期植株临界含氮量来表达氮素最大积累量，引入叶片潜在分配指数和茎鞘潜在分配指数2个品种遗传参数来区别不同品种在器官间的氮素分配差异，采用Richards方程来描述大麦花前氮素积累动态变化；采用指数函数方程来描述叶片氮的转移量随叶面积指数的动态变化以及籽粒从土壤中吸收的氮量随干物重的动态变化；采用非线性函数方程描述茎鞘和穗部的氮浓度随生理发育时间的动态变化。

Accumulation Effort (unit: lines) Measures the required accumulation/sortation effort.

集货量衡量需要订单合并/分类的量。

The result showed that the mineral oil content of soil was negatively correlated with microorganism contents,the mineral oil accumulation degree of stipa was more than that of Leymus chinensis and the Fe and Zn accumulation degree of Leymus.

结果表明：土壤矿物油含量与微生物含量成负相关；针茅对矿物油积累程度高于羊草；羊草对铁、锌的积累程度高于针茅等等。

But, in present, the distributed and floated deviation of educational resources has exceeded the limit, in which it could guarantee equal rights of citizen and well-worked of society, finally leaded to accumulation of educational resources. What's more, the accumulation becomes stronger and stronger as a result of character of resource structuration.
