Along the Mid Atlantic Bight a numerical density of 0-8 fish / 25 x 10 3 m 2 has been reported.
Using n as the number of nucleons ( in this case, protons ), we can introduce the degree of ionization 0 \ leq x \ leq1 so n _ e = xn, and the numerical density of neutral hydrogen is n _ h = ( 1-x ) n.
Density ( ? ), Acceleration ( a ), and a Wind Vector are sensed by two onboard instruments, the first is a high precision Accelerometer suite ( ACC ) that amplifies the ?g drag signal in the along track axis of the spacecraft . Secondary to that is a Neutral Mass Spectrometer ( NMS ) that can provide data products relating the wind vector with respect to the spacecraft ram-vector as well as the numerical density of the constituents in the atmosphere.
It's difficult to find numerical density in a sentence. 用numerical density造句挺难的
