Abstract: A champagne tower-type multi-stage throttle control valve includes a valve body, a valve cover, a throttle sleeve, and a valve core. A sleeve cavity of the throttle sleeve is shaped as a stepped hole with two or more layers. The valve core is shaped as a stepped shaft with two or more layers coaxial with the throttle sleeve. The number of shaft shoulders of the valve core is smaller than or equal to the number of hole shoulders of the sleeve cavity of the throttle sleeve, such that each set of shaft shoulders of the valve core in an axial direction can form a sealing surface fit with corresponding hole shoulders of the throttle sleeve. A flow channel groove is axially or obliquely formed on each of the hole shoulders of the throttle sleeve and/or the shaft shoulders of the valve core.

Abstract: Interleaved data acquisition in optical spectroscopy is used to provide interference correction for time-varying interference. Measurements at a reference frequency are used to provide an estimate of the interference. These reference measurements are interleaved with the remaining measurements in order to provide estimates of the interference vs. time at relevant times. The interference being corrected can be spectrally structured or unstructured.
