dynamo n. 1.【電學(xué)】發(fā)電機〔尤指直流發(fā)電機〕。 2.〔口語〕勤奮肯干的人,精力充沛的人。 an alternating [direct] current dynamo 交[直]流發(fā)電機。 a compound [wound] dynamo 復(fù)繞[復(fù)激發(fā)]電機。 shunt [wound] dynamo 分繞[并勵發(fā)]電機。
From the distribution of rotation period and convection parameter of m type stars , stellar chromospheric activity of m type stars depart from the anticipation of a . dynamo theory obviously 從m型主序星的自轉(zhuǎn)周期的和恒星內(nèi)部對流區(qū)隨色指數(shù)的分布來看, m型主序星的色球活動行為與發(fā)電機理論的預(yù)期有明顯的差異。

In geophysics, dynamo theory proposes a mechanism by which a celestial body such as the Earth or a star generates a magnetic field. The theory describes the process through which a rotating, convecting, and electrically conducting fluid can maintain a magnetic field over astronomical time scales.
