对于同一系统，环境效率越高，资源效率也越高
举一反三
- 对于同一系统，环境效率越高，资源效率也越高 A: 正确 B: 错误
- 中国大学MOOC: 对于同一系统，环境效率越高，资源效率也越高
- 对于同一系统，环境效率与资源效率关系是（ ）Which of the following describes a right relationship between environmental efficiency and resource efficiency for the same system（ ）? 环境效率与资源效率无关;The environmental efficiency is not related to the resource efficiency|资源效率越高，环境效率也越高;The higher the resource efficiency, the higher will be the environmental efficiency|环境效率恒等于资源效率;The environmental efficiency is always equal to the resource efficiency|资源效率越高，环境效率就越低;The higher the resource efficiency, the lower will be the environmental efficiency
- 对于过滤除尘，风速越高效率越高
- 高频开关电源系统效率指标必须满足系统负载率越高系统效率越高（）
