For JPEG Compression Ratios, 30:1 to 50:1 compression is possible with small to moderate defects, 100:1 compression is quite feasible for __________ purposes.
举一反三
- When 2 people performs cardiopulmonary resuscitation on an adult, the ratio of compression to ventilation is: A: 15：1 B: 15：2 C: 30：1 D: 30：2
- The _______ compression-ignition engine has a compression ratio of 16~24 to 1 and raises an induced charge of air to a pressure of 3~5 MPa . and a temperature of 500-800 oc at the end of the compression stroke.
- During<br/>adult cardiopulmonary resuscitation, the ratio of chest compression<br/>to ventilation was () A: 30:2 B: 20:2 C: 15:2 D: 30:1 E: 15:1
- The four strokes in the engine are, in order of<br/>occurrence((_____)) A: intake, power, exhaust, and compression B: intake, power, compression, and exhaust C: intake, compression, power, and exhaust D: intake, exhaust, power, and compression
- The displacement ductility of compression member will decrease with the increase of axial compression ratio.
