A lumen is a measure of the rate of emission of light energy . 流明是光能放射率的量度單位。
To undergo photodecomposition, a pesticide must first absorb light energy . 農(nóng)藥為進(jìn)行光解作用,必須首先吸收光能。
The photomultiplier converts the light energy signal into an identical electrical signal that can be easily manipulated and measured . 光電倍增管可將光能轉(zhuǎn)變成易于操縱或測(cè)量的電流信號(hào)。
It is assumed that the emission and absorption of light energy by an atom or molecule is not a continuous process but occurs in steps . 假定原子或分子發(fā)射光能和吸收光只能不是一個(gè)連續(xù)的過(guò)程,而是階梯式發(fā)生的。
To absorbing light energy and heat energy 吸收光能及熱能,促進(jìn)放射能量。
