This application discloses a structural optimization design method for a cassette optical system to address the technical problem of image quality degradation caused by structural deformation under high-impact and high-overload conditions. The method includes: establishing a parametric finite element model comprising a primary mirror, a secondary mirror, and a supporting structure; obtaining the displacement vector through equivalent static analysis; calculating the structural stiffness characterization function and three image quality characterization functions (change in primary-secondary mirror spacing, primary mirror deformation, and secondary mirror deformation); establishing a multi-objective weighted optimization model; solving for the optimized structural element density distribution; and reconstructing the structural model. This method can effectively suppress structural deformation under high-impact and high-overload conditions, improving the stability and reliability of the system's image quality.

The present application relates to cerebral vascular state early warning technical field, specifically to a kind of neonatal brain injury multi-modal assessment early warning system.The system is based on neonatal core body temperature adjustment standard pressure conduction delay interval at each monitoring moment, obtains the discrete event in time-constrained mismatched arterial blood pressure signal and local cerebral oxygen saturation signal, obtains event matching pair.All event matching pairs are extracted features, and cerebral vascular fluid resistance index is obtained.Arterial blood pressure and cerebral vascular fluid resistance index at each monitoring moment are used as two-dimensional data points, the distribution trend of two-dimensional data points under continuous monitoring moment is counted, and blood pressure early warning signal is determined.The present application obtains adaptive conduction delay interval as time constraint through temperature data, uses matching method to obtain event matching pair of real functional buffer result between arterial blood pressure and cerebral blood flow, and then carries out vascular functional feature analysis, to determine the reference strong blood pressure early warning signal.

The present application relates to the field of microwave parts assembly, in particular to a kind of assembly method for multi-channel waveguide rotary joint of multi-surface installation. After the assembly of joint and mechanism or structure is completed using the method provided by the present application, the residual assembly stress is small, which is insufficient to affect the performance of the joint. At the same time, the method solves the problem of the influence of the assembly stress of the multi-channel waveguide rotary joint and other parts after assembly on the isolation degree between the multiple channels of the joint, and has the advantages of simplicity, efficiency, operability and strong reference value. It has high reference significance for the assembly of other high-precision parts.

The invention provides an intelligent management method for medical record data of a head and neck surgery patient, and belongs to the field of data processing.The method comprises the steps that retrieval content and a final word unit in each historical medical record of the head and neck surgery patient are obtained; using a retrieval algorithm to obtain a historical medical record required by the doctor; obtaining the priority of each historical medical record required by the doctor according to the distribution of each final word unit in the retrieval content and the historical medical records required by the doctor; if a retrieval algorithm is used, the medical record cannot be retrieved; and according to the distribution of each final word unit in the historical medical record, obtaining the historical medical record required by the doctor, and further obtaining the priority. The method aims at solving the problem that when medical records needed by doctors are retrieved from a plurality of historical medical records of head and neck surgery patients through a retrieval algorithm based on Boolean logic at present, only the medical records needed by the doctors can be retrieved through the current retrieval algorithm, and the priorities of the retrieved medical records cannot be obtained.
