查询词典 impulsive

By comparison between SMM HXRBS observation and ground observation of Hα and CaIIK lines, especially through the combined study between SMM HXRBS observation and chromospheric flare models, the results show that: in the initial stage of impulsive phase, there is a correlative relation betweem Hα line intensity and hard X-ray emission; different spike in hard X-ray flux curve represents the burst at different location; the energy taken by non-thermal electron beam is larger than the radiative loss in chromosphere; for the flare studied here, the chromospheric evapporation is explosive; if the chromosphere is in balance between electron beam bombardment and radiative loss, the column mass density at the top of chromospheric flare model can not be taken as measure from the source of electrons and then the total material between the source of electrons and the top of chromosphere can be estimated.

通过一个具体耀斑的SMM HXRBS观测结果与同时基于地面得到的Hα和CaⅡK可见光谱观测结果对比，特别是将硬x谱观测结果与色球半经验模型联立研究，结果显示出：在脉冲相上升段，硬x发射与Hα辐射之间存在对应关系；硬x线光变曲线中不同脉冲爆发分量不太可能起源于同一位置；硬x辐射所反映的高能非热电子总携带能量大于色球总辐射损失；对所研究的耀斑而言，其色球蒸发过程是爆发性的；在详细比较了非热电子色球总沉积和色球辐射损失的基础上，指出半经验模型中色球顶部柱数密度不能看成是从非热电子源度量的，从而估计了色球顶部到非热电子源之间的总物质。

The detailed time-match semiempirical models represnting the chromospheric state during the impulsive phase of the 2B flare on Fab. 3 1983 are proposed by making the non-LTE calculstions on hydrogen and ionized calcium. The physical pictures of total evolutionary pattern of the impulsivs phase of the flare are improved either quantitatively or qualitatively in comparison with the former work we did.

利用南京大学太阳塔多波段光谱仪拍摄到的1983年2月3日2B级耀斑脉冲相期间的Hα和CaⅡK线轮廓系列光谱资料，按照我们所发展的构造定态色球耀斑半经验模型的方法，通过联立求解氢和一次电离钙的能级平衡方程和辐射转移方程，建立了能够再生Hα和CaⅡK线观测轮廓的更为完整的1983年2月3日2B级耀斑脉冲相色球半经验模型。

第三章，通过建立L-算子不等式，运用M-矩阵的理论和随机分析技巧，获得了一类脉冲随机泛函微分方程均方指数耗散的充分条件。

The robust dissipativity for given supply rate has been studied for uncertain impulsive systems. The dissipativity conditions for such systems are derived by means of storage function method, matrix inequality and dissipativity inequality.

对不确定脉冲动力系统在给定供给率时的鲁棒耗散性进行了研究，利用储存函数法、矩阵不等式以及耗散不等式等方法，得到了不确定脉冲系统的鲁棒耗散性的充分条件。

One mechanism, measured in other experiments testing toddlers' ability to resist temptations, is called effortful self-control — how well you can think ahead and deliberately suppress impulsive behavior that hurts yourself and others.

一种反应机理叫做努力的自我控制，可以用来衡量幼儿的抗拒诱惑的能力。另外一个则是理性比较少的负疚感，对自我控制能力差的孩子和成年人尤其有用。

One mechanism, measured in other experiments testing toddlers' ability to resist temptations, is called effortful self-control - how well you can think ahead and deliberately suppress impulsive behavior that hurts yourself and others.

其中一种被应用于其他的测试孩子抗拒诱惑的能力的试验中。这种方法被称之为努力自我控制，也就是你如何很好地超前思考，并且从容不迫地抑制住这种会伤害你自己，也会伤害他人的冲动性行为。

People with frontotemporal dementia engage in inappropriate and impulsive behavior and sometimes even carry out criminal acts such as shoplifting.

额颞痴呆患者有时出现不适当的冲动行为甚至入店抢劫等犯罪行为。

Alpha-stable distribution, a generalization of Gaussian, was better for modeling impulsive noises than Gaus- sian distribution in signal processing.

α-稳定分布可以更好地描述实际应用中所遇到的具有显著脉冲特性的随机信号和噪声。

Hyperkinetic children are often reckless and impulsive, prone to accidents, and find themselves in disciplinary trouble because of unthinking breaches of rules rather than deliberate defiance.

过动症儿童常常是鲁莽的，易冲动的，易於发生意外，和发现自己陷入被惩戒的麻烦，乃因为不去思考规则胜於考虑违反之结果。

By taking thecondition into account that the impulsive times are fixed,some criteria are established inSection 3.1 to judge the stability of the systems in terms of two measures.

在§3.1中，考虑了脉冲时刻固定的情形。借助于变异Lyapunov方法、比较原理和逐段连续的Lyapunov函数，我们建立了一些这类系统依照两种测度的稳定性判定准则。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
