到底是infer(推断)了什么?
The relationship between tidal volume and dead space during high-frequency ventilation is crucial to an understanding of the technique. It is useless to infer values for tidal volume and dead space from measurements made under other circumstances, yet it is very difficult to make direct measurements of these variables under the actual conditions of high-frequency ventilation, especially in humans.
高频通气时,潮气量和无效腔间的关系对于理解高频通气至关重要。在其他通气模式下通过测量推导潮气量和无效腔的值对于理解其通气模式是无用的,然而在高频通气下,尤其是在人体中,潮气量和无效腔这些变量很难直接测量。
是这个意思吗?other circumstances是与high-frequency ventilation相对的“通气模式”?infer(推断)的是“潮气量和无效腔”,难道“在其他通气模式下”潮气量不能直接“测量”,到底是infer(推断)了什么?
It is useless to infer values for tidal volume and dead space from measurements made under other circumstances从其他情况下的测量值推断潮气量和死腔的值是没有用的,字面翻译时这样,但是这样与上句话又无关了
