以两端简支圆柱壳体为例,研究了考虑正、余弦模态成分影响的圆柱壳体动力响应中的模态参与问题,提出了根据模态参与因子的分布特征判定模态截断阶次的方法,采用正、余弦模态叠加得到了圆柱壳体在冲击激励及旋转行波激励作用下的动力响应,基于响应的收敛性验证了判定方法的可靠性。理论计算与有限元仿真结果表明,与圆柱壳体模态特性分析不同,在求解圆柱壳体动力响应时必须同时考虑正、余弦模态成分的影响;冲击激励作用下,圆柱壳体各阶正、余弦模态在响应中的参与程度与激振点和观测点的位置相关;旋转行波激励作用下,圆柱壳体各阶正、余弦模态在响应中的参与程度与激励的阶次和频率密切相关。

Atomic simulations are executed to investigate the creep responses of nano-polycrystalline(NC) niobium established by using the Voronoi algorithm. The effects of varying temperature, applied stress, and grain size(GS) on creep properties and mechanisms are investigated. Notably, the occurrence of tertiary creep is exclusively observed under conditions where the applied stress exceeds 4.5 GPa and the temperature is higher than 1100 K. This phenomenon can be attributed to the significant acceleration of grain boundary and lattice diffusion, driven by the elevated temperature and stress levels. It is found that the strain rate increases with both temperature and stress increasing. However, an interesting trend is observed in which the strain rate decreases as the grain size increases. The stress and temperature are crucial parameters governing the creep behavior. As these factors intensify, the creep mechanism undergoes a sequential transformation: initially from lattice diffusion under low stress and temperature conditions to a mixed mode combining grain boundaries(GBs) and lattice diffusion at moderate stress and mid temperature levels, and ultimately leading to the failure of power-law controlled creep behavior, inclusive of grain boundary recrystallization under high stress and temperature conditions. This comprehensive analysis provides in more detail an understanding of the intricate creep behavior of nano-polycrystalline niobium and its dependence on various physical parameters.

应用^15N示踪技术研究了大田条什下氮肥用量与运筹对水稻氮素吸收、转运及籽粒产量的影响。试验分别设置3个氮肥水平（0、150和240kg／hm^2N）和两种基追比例（即基肥：蘖肥：穗粒肥分别为40％：30％：30％（A）和30％：20％：50％（B）），共5个处理，依次记作N0、N150A、N150B、N240A、N240B。结果表明，在0—240kg／hm2范围内，提高氮肥水平，显著增加水稻吸收的肥料氮素、土壤氮素数量以及肥料氮在土壤中的残留量。成熟期高氮处理（240kg／hm2）水稻吸收的肥料氮素、土壤氮素及肥料氮在土壤中的残留量较多，分别为110．25、65．91、32．69kg／hm2，而氮素的吸收利用率和土壤残留率下降，氮素损失率增加。在相同的氮肥水平下，采用基肥：蘖肥：秘粒肥比例为30％：20％：50％时，水稻吸收的肥料氮数量显著增加，氮素吸收利用率和土壤戏留率提高，氮素损失率降低。适量施氮并增加穗粒肥的施氮比例，可以显著增加水稻产量。在本实验条件下，施氮量为240kg／hm2及丝肥：蘖肥：穗粒肥为30％：20％：50％的施氮处理是兼顾产量和环境的最佳氮肥运筹方式。

研究了大田条件下氮肥水平(常规施氮肥(187.5 kg/hm2)、减氮28%(135.0 kg/hm2)和不施氮肥(0 kg/hm2)对不同基因型水稻(粤晶丝苗2号、桂香占、华优8305和天优998)的源库特性的影响。结果表明,减氮不会导致华南早晚兼用型水稻产量显著降低在于其能维持或促进水稻的源库协调性。与常规施氮比较,减氮28%有利于提高粤晶丝苗2号、桂香占及华优8305的产量,增幅分别为11.99%,5.51%,6.46%,主要归因于减氮28%能增强后期叶片光合或茎鞘转运而有利于稳定高产形成。减氮28%有利于提高粤晶丝苗2号和桂香占库容和粒叶比,提高华优8305库容有效充实度,而对天优998无显著影响。
