برادرا یه همتی می کنید این 9 تا جمله رو یه جوری که از لحاظ علمی قابل فهم باشه سرهمش کنید! ممنون می شم
Start/stop operation with the alternator also requires a high short-time power supply, which could be recovered by means of braking energy
Chassis can be realised that are able to even out irregularities of the road and compensate driving dynamics.
Nevertheless, the changeover to Chrome-III containing or chrome-free passivations proves to be difficult
Fine particles that are uniformly distributed over the entire matrix, exploiting the process of dispersion hardening, are responsible for the currently used high-strength steel alloys
Starting with silica tetrachloride, small, spherical single silica parts with a mean diameter in the range between 7 and 40 nanometres result from flame hydrolysis
On this scale, material-dependent interface effects and large specific surfaces observable in larger structures become more important
The critical size below which material properties change depends on the material itself
The specific surface of a gram of nanocrystalline powder can have the size of a soccer field depending on the grain size of the material
Underlying these effects is a decrease in grain size so that dimensions are reached below which deformation mechanisms cannot occur in the grain itself
