Yield (mg/min): Mass of product per minute, used to evaluate fabrication efficiency. 2. Diameter Range (nm): Diameter range of the as-prepared carbon nanotubes, measured in nanometers. 3. Number of Walls (layers): Number of layers of multi-walled carbon nanotubes. 4. Purity (%): Purity of carbon nanotubes in the final product, expressed as a percentage. The comprehensive efficiency E is a weighted sum of the following factors: - Yield (Y): weight = 0.4 - Purity (P): weight = 0.3 - Number of Walls (W): weight = 0.2 - Diameter Range (D): weight = 0.1 (requires conversion to a normalized score) The comprehensive efficiency can be calculated as: E = 0.4×Y + 0.3×P + 0.2×W_score + 0.1×D_score Here, the W_score and D_score can be obtained by standardizing the original values, such as via linear interpolation or normalization methods.
