apparent variable 中文意思是什麼
apparent variable
解釋
視變量-
The longer the period, the brighter the star is. thus, by measuring the period of a cepheid variable, we know its absolute magnitude, hence, we can tell how far it is away by comparing with its apparent magnitude
所以，只要知道某一造父變星的周期，我們便可得知它的絕對星等，只要和它的視星等作比較，便可以求得它和我們的距離。 -
We have to use some other methods to measure the luminosity or equivalently the absolute magnitude of the cepheid variable. since we can readily measure the apparent magnitude of a cepheid variable, to measure the luminosity means measuring the distance. we use some distance measurement methods, for example, parallax, to determine the relation
要弄清這個關系，我們要知道不同造父變星的光度和光變周期數據，量度光變周期當然不是問題，但要得知一顆恆星的光度，我們首先要得知它的距離，這時便須藉助好像視差法等其他量度天體距離的方法。 -
In summer, load is affectd by meteorological elements greatly. based on multidimension time series approach, the car model is constructed, which could take account into the accumalated influence from temperature and inertia action from historic load, meanwhile, the advantage of the model is that its expreaasion is in the form of apparent function, which could provide us some quaqutive imformation existed between input variable and output variable
本文以多維時間序列分析方法為基礎，成功地解決了未來日負荷與前些日負荷慣性變化的影響，以及氣象累計效應的影響顯性函數關系問題，從而為負荷預測人員掌握未來負荷與歷史負荷，歷史氣象要素與當日氣象條件之間的規律，提供了量化的分析基礎。
