Dear research community,

I am currently working on my thesis on the diagnostic accuracy of respiratory oscillometry in COPD. Unfortunately, I do not have institutional access to several relevant Chinese publications that are only available on CNKI/CQVIP. I would be very grateful if anyone with access could kindly help me obtain the full-text PDFs of the following articles:
