本发明公开了一种检测呼出气中NO和/或丙泊酚的方法。本方法以离子迁移谱技术为基础,用空气作为载气和漂气的供气气源,可同时测量、也可先后或单独测量呼出气中的NO和丙泊酚的含量。将这种方法用于呼出气中的NO和丙泊酚的检测,具有检测速度快,灵敏度高,能够实现无前处理直接测量以及实时在线监测等优点。这种方法对丙泊酚和NO的检测限分别可以达到0.5ppb和4ppb。
Relative binocular disparity cannot tell us the absolute 3-D shape of an object, nor its 3-D trajectory if it is moving, unless the visual system has independent access to how far away the object is...
This letter experimentally demonstrates a multiservices hybrid access network integrated radio-over-fiber and fiber-to-the-home systems which share the same distributed architecture. A 1.25-Gb/s baseb...
FIBER-TO-THE-x (FTTx) have been widely constructed for high data rate wired services to provide triple-play services including voice, data, and video [1]. On the other hand, radio-over-fiber (RoF) tec...
We experimentally demonstrate efficient detection of a 1.2-Tb/s 24-carrier NGI-CO-OFDM signal with 12.5-Gbaud PDM-QPSK carrier-modulation by simultaneously recovering 2 or 3 carriers per 50-GSamples/s...
We demonstrate 10Gb/s VCSEL transmission for WDM PON over 23.6km single mode fiber. Dispersion penalty is limited to 2.9dB by introducing a wavelength offset with respect to the remote array waveguide...
We demonstrate the generation of a novel 1.2-Tb/s NGI-CO-OFDM superchannel comprising of 24 frequency-locked 12.5-GHz spaced PDM-QPSK carriers, and transmit it over 72x100-km of ultra-large-area fiber...
Evaluation of the back-propagation step size for SPM compensation in a coherent receiver shows that setting step size to the amplifier section length extends the distance of 111Gb/s transmission from ...
We evaluate the OSNR tolerance of 111Gb/s No-guard interval OFDM signal using low sampling rate analogue-to-digital converter. The back-to-back experiment shows that the OSNR penalty is less than 0.1d...
Ten 25-GHz-spaced wavelength-division-multiplexed channels using 112-Gb/s polarization-division-multiplexed 16-QAM are transmitted over 1022 km of standard single-mode fiber. Owing to electrical-drive...
We demonstrate the record capacity-distance product of 48.2 Petabit/s.km by using 111-Gb/s no-guard-interval coherent OFDM with 2-b/s/Hz spectral efficiency.
