The strong wear-resistant application environment requires the temperature sensor to be flexible, durable, high-precision, and good long-term stability. The sheathed platinum thermistor sensor with nitride nano coating prepared by magnetron sputtering is selected. First, in order to improve the effectiveness and accuracy of the thermal stability observation data of platinum resistance sensor, the stability and reliability of the observation equipment are evaluated; through analysis, it is determined that the main factors affecting the uncertainty of platinum resistance temperature sensor are measurement repeatability, the stability and uncertainty of standard thermometer, the resolution of the thermometer to be tested, and the non-uniformity of the calibration bath temperature, etc., and an evaluation model for the reliability of the calibration results of platinum resistance temperature sensor is established. Then, by selecting the resistance value of the sheathed platinum thermal resistance sensor under the water three-phase point as the stability comparison benchmark, a high-precision test evaluation system is designed, which is not greater than 3mK. Finally, the high temperature electrical life test, temperature shock test and natural storage test were carried out for the sheathed platinum resistance sensor, and the long-term thermal stability of the sheathed platinum resistance sensor based on the nitride nano coating was evaluated to reach 8mK, meeting the requirements of international regulations for platinum resistance.

In the finite element analysis of large multi-roll turntable bearing, in order to avoid the high nonlinearity of the model, rod element is usually used to replace the contact relationship between the roller and the raceway. Therefore, determining the relationship between the contact deformation and the contact force of rod element is the key to establish the correct finite element model of large multi-roll. Based on Hertz contact theory, this paper analyzed the influence of rolling element contact deformation parameters, based on the materials on the basis of the plastic deformation of single roller extrusion model and extract the relationship between the rolling element contact deformation and contact curve, the analytical solution compared with Hertz contact theory and the results show that the finite element model considering plastic deformation can better reflect the rolling body contact process of plastic deformation, the relationship between the contact deformation and contact pressure curve showing a strong nonlinear.

In this paper, the impact of pre-oxidation on the formation of disinfection by-products (DBPs) during subsequent chlorination of intracellular organic matter of Microcystis aeruginosa was investigated. The results showed that with the increase of CIO2 dosage, the yields of trichloromethane (TCM), dichloroacetic acid (DCAA), trichloroacetic acid (TCAA), dichloro acetonitrile (DCAN) and trichloronitromethane (TCNM) decrease, while the yields of chloral hydrate (CH), 1, 1-dichloro propanone (1, 1-DCP), 1, 1, 1-trichloro propanone (1, 1, 1- TCP) increase firstly and then decrease. With the pH increasing, the yields of TCM increase, and the yields of CH and TCNM increase with the pH increasing from 5 to 7, then decreased. The remaining 5 species of DBPs decrease. With the pre-oxidation time prolonging, the yields of DCAA, TCAA, DCAN and 1, 1-DCP decrease, the yields of TCM, CH and 1, 1, 1-TCP gradually increase, while the yields of TCNM was increased firstly and then decreased. With the increase of temperature, the yields of DCAA, TCAA, TCM, CH and 1, 1, 1-TCP increase, the yields of DCAN and 1, 1-DCP increase firstly and then decrease, while the yield of TCNM decrease continuously. When the temperature is controlled at 20°C, the yields of DCAN and 1, 1-DCP reach the maximum value.

Aiming at the implementation of the power supply noise suppression method, a power supply noise suppression method based on energy domain control is proposed in this paper. The power supply noise model based on energy domain control was established on the basis of the electromagnetic field energy model, the differential- mode power supply noise energy model, the common-mode power supply noise energy model, and the total power supply noise energy model. The coupling path of noise was analyzed, and the specific methods of differential-mode noise electromagnetic field intensity control based on resistive coupling path, common-mode noise electromagnetic field intensity control based on capacitive coupling path, and common-mode noise electromagnetic field intensity control based on inductive coupling path are proposed. The experimental results show that the proposed power supply noise suppression method based on energy domain control can effectively suppress the differential-mode noise and common-mode noise of the power supply, and reduce the power supply noise interference.

In the process of oil and gas field exploitation, high-precision micro nano CT is a highly sophisticated technology widely used to study the occurrence and distribution characteristics of micro residual oil. In order to study the producing degree of micro residual oil by different EOR methods, the micro residual oil is finely described according to the CT scanning results of core pores and internal fluids. The results show that the X-ray emitted by micro nano CT can effectively overcome the image information confusion caused by information overlap in traditional X-ray imaging. Double ray source, high test precision, resolution up to 500nm;Under the condition of not destroying the sample state, scanning from small sample to large sample can be realized, and three-dimensional digitization can intuitively describe the pore structure of the sample, so as to realize micro nano rock imaging; Micro/nano CT scanning technology can be combined with core dynamic displacement experiment unit to quantitatively characterize the micro residual oil saturation after different displacement methods;After polymer flooding, binary composite flooding and heterogeneous composite flooding, the micro remaining oil saturation is 22.3%, 18.4% and 12.0% respectively;After image processing of CT scanning data, the results of solid, oil and water three-phase two-dimensional segmentation can be obtained. According to the two-dimensional data of the core, the pore structure of the core at different layers and the microscopic remaining oil can be reconstructed in three-dimensional space to obtain the visual distribution map of oil, water and rock in three-dimensional space;After chemical flooding, the remaining oil saturation in different pore diameters has decreased, but polymer flooding and binary composite flooding have μ The degree of producing remaining oil in the pores below m is low, and the heterogeneous oil displacement system can be further used less than 5 $mu$ M residual oil in pores. It is of great guiding significance to reasonably adjust the development mode by elaborately describing the micro residual oil distribution after different displacement modes.

A high cable ratio of urban distribution network is easy to cause the problem of harmonic resonance. Nonlinear customers inject harmonics into the power grid in operation, resulting in harmonic issues. This study proposes a method of harmonic emission level based on correlation vector machine regression. Firstly, the Norton equivalent circuit of customer is established. The harmonic impedance at the system side is obtained via the correlation vector machine regression model utilizing the metrical data of the common connection point as the input vector, and the harmonic emission level of nonlinear customers is then estimated. The proposed method overcomes the problems of support vector machine method, kernel function must meet Mercer condition, and parameters are difficult to determine. The effectiveness of the proposed method is verified by simulation analysis.

If the fault location on the power cable can't be quickly found and eliminated in time, it will cause the interruption of electricity for domestic use and power supply for industrial and mining production, resulting in economic losses. Therefore, combining wavelet transform with decision tree, random forest and SVM (support vector machine), this study proposes a method to identify cable faults, and builds the corresponding cable fault model in MATLAB. The simulation results of the model show that the model can greatly improve the calculation efficiency of cable fault, can quickly identify and accurately locate the fault, and has higher accuracy than other traditional identification methods, which can be widely used in online real-time accurate monitoring and diagnosis of cable fault.

The Coriolis vibratory gyro detects the standing wave mode angle through a pair of orthogonal detection electrodes, and the non-orthogonality of the detection electrode may cause an error in the standing wave vibration angle detected by the gyro, affecting the accuracy of the gyro. Aiming at the problem of non-orthogonality in the detection electrodes of the Coriolis vibratory gyro, a non-orthogonal error calibration method for the gyro detection electrode is proposed in this paper. Starting from the angle measurement principle of the Coriolis vibratory gyro, the angle detection error model in the presence of non-orthogonal error of the detection electrode is derived, and a discrete calibration method for the non-orthogonal error of the gyro detection electrode is proposed, which considers the influence of gyro drift. The experimental results show that the calibration accuracy of the non-orthogonal error of the detection electrode is superior than 3”, which fully meets the performance index of the gyro.
