查询词典 negatively

Acetate groups charge ZnO nanocrystals negatively and passivate the surfaces,reducing the surface defects and visible emission centers. Resultantly, the increase of acetategroups lead to the quench of visible emission and improvement of photoluminescenceproperties. At appropriate concentrations, the hydroxide groups mainly passivate the surfaceand improve the photoluminescence properties.

研究发现，氢氧化锂/醋酸锌的比值对胶体氧化锌量子点的发光性质有重要影响；醋酸根基团通过使氧化锌粒子带负电荷并钝化其表面，使得氧化锌纳米点的表面缺陷和可见发射中心大大减少，因此醋酸根浓度的增大导致了可见发光的淬灭和发光性质的增强；氢氧根基团在中等浓度时主要起钝化氧化锌表面的作用，使产物的发光性质得到改善。

Rutter and Fielding (1988), for instance, found that a perceived need to suppress genuine felt emotion in the workplace is negatively associated with job satisfaction.

例如，Rutter and Fielding (1988)，发现在工作场所内觉察到的要抑制发自内心的情感的要求对工作满意度起着消极的作用。

Grain quality affected by N application and plant density could directly influence malting quality. Grain protein content was negatively correlated to steeping degree and steeping rate, and positively related to saccharogenic power. The relationship of grain protein content to a -Amino-nitrogen content and kolbach index could be expressed with a quadratic curve equation, respectively. The greatest decomposition rate of protein might be achieved when grain protein content was 11-12%.

施氮量、氮肥运筹比例和密度对籽粒品质的影响直接影响着麦芽品质，籽粒蛋白质含量下降，浸麦度和浸出率上升，糖化力下降，籽粒蛋白质含量和库值、氨基氮呈二次曲线关系，籽粒蛋白质含量在11%一12%时，其蛋白质分解速率最快，麦芽总氮与籽粒总氮呈极显著的正相关关系，在麦芽的生产过程中氮的消耗率与籽粒总氮为极显著的负相关关系。
