查询词典 luminosities

We studied the relation between their radio and optical luminosities and found a nearly linear correlation.

所得研究结果表明，射电噪类星体的射电光度与光学光度之间存在线性相关性。

The discharge is composed of threezones with different luminosities. Discharge current is in the order of mA.

等离子体区有明显的分层现象，从阴极到阳极分别为很短的白炽发光区，暗区和占据绝大部分间隙的淡紫色的发光区。

Such stars indicate their luminosities by their periods of variability and are used to tell the distances of distant galaxies.

通过研究这类恒星亮度的周期性变化，可以得知遥远星系的距离。

And the merging of the two luminosities continuous and spontaneous

两种光明自然地融合，一切妄想都彻底解脱

A dim foreground star and a bright star located much farther away -- whose light can be diminished by interstellar gas -- can be hard to tell apart because they appear to have similar luminosities as stars in our own galaxy.

一个光线暗淡的前景星星和一个位于远的多地方的光亮的星星-－－其光芒可能由于星际气体而被削弱－－两者之间很难区分，这是由于在我们自己的星系内它们都发出的是相同的光度。

We carried out a statistical test on the peak position of the big bluebump of medium/small redshift AGNs of different luminosities.

对中小红移不同光度AGN的大蓝包位置进行了统计检验。

In the BEPC electron positron storage ring, the bunch length and its lengthening are quite important characters. It determines the efficiency of getting physical events and the luminosities achievable, and it plays a key role in the upgrade of BEPC.

在北京正负电子对撞机中，正负电子束团的长度及其拉伸是束流性能重要指标之一，它直接影响到物理实验的效率，对BEPC的改进和性能进一步提高也起着关键的作用。

Using a fitting method which can reasonably assign weight to the observational data including two quantities with different dimensions, we obtain a V-band MRL based on the dynamical masses and luminosities of 203 main sequence stars. Compared with the previous work, the improved MRL is statistically significant, and the relative error of mass estimation reaches about 5%.

利用一个能合理分配两个不同量纲观测量权重的拟合方法，根据203颗恒星的动力学质量和光度数据给出了主序星的V波段经验质光关系，该结果对此前结果的改进不仅具有统计显著性，而且其对恒星质量估计的相对误差已达到约5%。

The study about the flux and index of gamma-ray loud blazars show:(1)there is significant correlation between the luminosities in gamma-ray and VLBI radio energy band;(2)there are strong anticorrelarions among the observed indices of soft X-ray, hard X-ray and gamma-ray. For the FSRQs, the whole X-ray emission was contributed by synchrotron self-Compton emission, for the HBLs, the X-ray emission was dominated by synchrotron emission while the soft X-ray emission is dominated by synchrotron emission and the SSC emission dominate the hard X-ray energy band for LBLs;(3) there are strong radio-radio and radio-optical flux correlations for the quasar 3C 273. The higher frequency emission leads those in lower frequency. The multi-band complex indices strongly correlated with the high frequency flux which implies that the object is becoming bright when the energy spectrum is harden.

通过对γ噪Blazar天体的谱指数、流量的相关研究，发现（1）51个样本blazar的γ射线光度与VLBI光度之间存在显著相关；（2）软X、硬X以及γ波段的观测谱指数之间存在较强的反相关，对FSRQs，无论是硬X射线还是软X射线的辐射都是逆康普顿辐射的贡献，而对于HBLs来说，则是同步辐射的贡献，对LBLs，在软X射线波段以同步辐射贡献为主，在硬X射线能区以逆康普顿贡献为主；（3）3C 273的射电各个波段以及光学之间存在强相关，高频辐射一直领先低频辐射，3C 273的多波段复合谱指数和高频流量之间存在强的反相关，意味着当能谱变硬时对象变亮。
