Monitoring of the regional cerebral oxygen saturation (SrO 2 ) using near-infrared spectroscopy (NIRS) is a non- invasive method to observe the oxygen balance of the brain. In the present study, we hypothesized that the effects of sevoflurane and propofol on SrO 2 in patients undergoing CEA with deficits of CBF, were different compared to those without any CBF deficits.

Determination of the nutritional composition of rabbit meat and analysis of individual amino acids and fatty acids was realized with the Nicolet 6700 by FT-IR method (Fourier transformed infrared spectroscopy). The principle of this method is the infrared absorption spectrum of the sample passes and there is a change from the rotary vibrating energy conditions of the molecule depending on the changes of the dipole moment of the molecule.

The detection of the internal quality of agricultural products, such as protein, moisture, sugar content, acidity, etc., mainly relies on spectral technology, especially near- infrared spectroscopy (Ling et al., 2019). However, near- infrared spectroscopy can only detect a very small area of the detection object, and cannot carry out large-scale spatial detection.
