The phrase "affects the variation of" is correct and usable in written English.
It can be used when discussing how one factor influences or changes the differences in another factor or variable.
Example: "The temperature affects the variation of plant growth rates across different species."
Alternatives: "influences the differences in" or "modifies the variability of".
From tests and analysis results, it was found that wall friction greatly affects the variation of formwork pressure over time.
It is shown that conduction in the particle strongly affects the variation of the vaporization rate with time and that the present version of the model well fits both the shape of the plots and the maximum heavy metal vaporization rates for all bed temperatures.
Also, wind velocity affects the variation of convective heat loss coefficient.
Since ambient index affects the variation of the effective refractive index of the core mode more than that of the cladding mode, increasing ambient index makes the resonant wavelength of the proposed PCF-based LPG shift to longer wavelengths.
Since the dispersion of the core mode in the PCF is higher than that of the cladding mode, ambient index affects the variation of the effective refractive index of the core mode more than that of the cladding mode [14].
The grid strength affects the variation on absolute value of terminal voltage phase angle.
The results indicate that liquid viscosity significantly affects the variations of pressure gradient, void fraction, velocity profiles, film thickness and wave behavior.
Lastly, the setting of the superposition of IGWs and the vertical electric field affects the variations of neutral atmosphere composition just as the IGWs itself, and the variations of the meridional electric field just as the vertical electric field itself.
Moreover, we investigated the key factor which is affecting the variation of observed ground motions.
The results show that the fuel mass flow rate is the dominant factor affecting the variation of energy efficiency and total cost rate.
This implies that there is a need to consider more parameters, including EUV and F10.7, that can affect the variation of vTEC during equinox seasons.
