"material ratio" is an acceptable phrase in written English.
You can use it to describe the relative proportions of different substances used in a mix or a recipe. For example, "The material ratio of cement to sand used in this concrete mix must be 5:1."
This method, based on the material ratio (Abbott) curve is very easy.
Cycling stability and rate capability are reported under realistic conditions of low carbon content (~10 wt%), low electrolyte/active material ratio (~1.2 µl mg−1), low cathode porosity (~55 vol%) and high mass loading (>10 mg cm−2).
The key parameters considered for the UPAE included solvent type, temperature, ultrasonic power, solvent to material ratio and extraction time.
The effect of carbonization temperature, raw material ratio on the catalytic activity for formic acid decomposition were investigated in details.
A uniform experimental design was used to optimize critical parameters (extraction time, liquor to material ratio and air flow).
The independent factors include extraction time (A), extraction temperature (B) and water to raw material ratio (C).
The independent factors included extraction time (X1), microwave power (X2) and water to raw material ratio (X3).
The effects of temperature and of the core to wall material ratio were found to be significant for all responses.
For this purpose, the water to cementitious material ratio and the amount of cementitious materials were changed.
Resin/filling material ratio has been determined as 10 90%, 15 85% and 20 80%, e-plastic/filling material ratio has been decided to be 0%, 5 %, 15 and 25%and25%
The morphologies of 3D nanostructure can be controlled by adjusting the raw material ratio of pyrrole to GO.
