Abstract: The present disclosure relates to a non-destructive in-situ measurement device and method based on Raman analysis. The device comprises: a laser light source that emits a laser beam; a focusing component that focuses the laser beam above a movable sample stage, with the focal plane of the focusing component positioned at an initial position. During measurement, the focal plane is controlled to move from the initial position to the surface, side, or bottom of the structure under test. The movable sample stage holds the sample to be measured and can move in a plane perpendicular and/or parallel to the optical axis. The axis of the structure under test is parallel to the optical axis and located within the laser beam's focal region. A detection module collects specific Raman scattering signals returned from the sample under test, and the structure's planar and three-dimensional parameters are determined based on the collected results.

Abstract: A method for data storage includes determining an expected expiration time of a new data file based on attribute information of the new data file and recorded attribute information of data files, in response to creation of the new data file in a level of a Log-Structured Merge Tree (LSM-Tree). Additionally, a block set corresponding to the expected expiration time is allocated for the new data file in a storage device. The recorded attribute information of the data files indicates a level where each of the data files is located, key information of each of the data files, and lifetime information of each of the data files. The data files that have been created comprise unexpired data files or both unexpired data files, and expired data files that expired within a preset period before creation time of the new data file.
