|
| Method | Value / (m·s-1) | Pros and cons |
|---|
| Numerical simulation | 576 (Ni/Cu)[28] | Poor accuracy; | | 620-630 (Ni/Ni)[30] | convenient; | | | fast and economical | | Deposition efficiency | 582 (Ni/Cu)[35] | Moderate accuracy and experiment cost; | | | unable to consider the influence of factors such as particle size in detail | | Single particle measurement | 512 (Ni/Cu)[35] | The accuracy is the highest; | | 650-660 (Ni/Ni)[36] | the influence of factors such as size and oxide film can be considered |
