increasing or decreasing forces provided that the frequency is not too high can also be measured with hydraulic force transducers 假如頻率不是很高的話,漸強(qiáng)或減弱的力也能用這款液壓力傳感器測量。
the preterm group continued to have decreased forced expiratory flows and normal forced vital capacities in the first and second years of life compared with the full-term group, even though their increases in lung function with growth were similar to those of full-term infants 盡管早產(chǎn)組的嬰兒隨著生長,肺功能的增強(qiáng)與足月組的嬰兒相似,但在第一和第二周歲的時(shí)候,早產(chǎn)組和足月組的嬰兒相比用力呼氣流量和正常的肺活量持續(xù)減少。
