1) number of inflationary efolds
暴涨指数
1.
Particularly,the expected number of inflationary efolds is studied carefully.
回顾了现代宇宙学的历史和现状,从Friedmann方程出发,将标量场的量子涨落作为Gaussian白噪声,建立了反映宇宙暴涨过程的Langevin方程,得到尺度因子的均值、自相关系数和方差;特别是详细计算了暴涨指数,发现用这种方法得到的暴涨指数与经典结果差异甚微。
2) inflation
[英][ɪn'fleɪʃn] [美][ɪn'fleʃən]
暴涨
1.
when scalar field as outer field is inhomogeneous and is regarded as torsion potential of space-time s torsion, the exponential multiplying power-law inflation may occur in the very early stage of the universe.
证明了在非均匀球对称的Tolman-Bondi时空中,应用Brans-Dicke理论,当作为外场的B-D标量场是非均匀的,且将其视为时空挠率的挠率势时,选取合适的拉氏作用量,则极早期宇宙将以指数幂律倍增的形式发生暴涨。
2.
When matter spin interaction is considered,the energy content of the universe is spin dominated,effective inflation can occur and the universe is radiation and dust dominated at a sufficiently early epoch.
Gasperini给出的自洽的引力场方程,当考虑自旋与自旋的相互作用时,发现自旋密度对极早期宇宙起支配作用,是引起暴涨的根本原因,而且极早期宇宙是以辐射和尘埃为主,同时,由该模型得到一个非零的最小“宇宙半径”和初始密度。
4) exposure index
暴光指数
5) rainstorm attenuation coefficient
暴雨指数
6) hail storms index
雹暴指数
1.
The results indicate that the thermal infrared brightness temperature of hail cloud(CH31,CH32,CH35)are all less than 240K,the reflectance of mid-infrared wave band(CH20)is relatively low < 30%,the reflection index of visible light and short infrared wave band(CH1,CH6)>80%,hail storms index≥0.
针对冰雹灾害多发的新疆天山西部地区,利用2007年和2008年5—10月14次MODIS卫星过境资料,选取共计45个云系样本数,进行冰雹云、强对流云团和薄卷云的光谱特征提取和雹暴指数计算与分析。
