Transmitter source is a significant part of a remote-exploration acoustic logging tool. Its power and directional-radiation characteristics are key factors that affect the tool performance. Plasma source features high power and wide band. Thus, it is expected to significantly improve the exploration depth while maintaining the resolution in remote-exploration logging. However, it cannot generate a directional acoustic field, which seriously undermines its advantages as a logging source. Therefore, exploring a suitable method for directional radiation in a plasma source is necessary. In this study, a two-dimensional axisymmetric formation model with a borehole is developed using the finite-element numerical simulation. The characteristics of the plasma source with a small rotating parabolic reflector in an open hole are simulated, such as the energy accumulation and directional radiation. The simulation results reveal that the parabolic reflector in our model can increase the acoustic pressure by more than 10 dB and narrow the - 3dB angle to approximately 60° in a formation 1 m away from the source. This scheme is primarily verified as a feasible method for directional radiation, which can improve the usefulness of a plasma source in remote-exploration acoustic logging.

The distance between elevator car and shaft wall is an important index of elevator safety. Inappropriate distance may cause falling dangers. The traditional method of measuring the distance is complex and inefficient. The inspector needs to get on the car roof and operate the elevator stopping at appropriate positions in turn. Each time elevator stops, the inspector selects several points to measure. The device bracket designed in this article can make the inspection more convenient and efficient. The device is composed of a custom-designed bracket and multiple laser rangefinders which includes three horizontal ones and a vertical one. The bracket contains beam, bracket plane, telescopic bracket, adjustable screws, sliding block, magnetic base and telescopic legs. The device bracket can adjust the position and direction of the laser rangefinder and keep the device adsorbing on the car roof by magnetism. The device can measure and judge the results automatically, greatly reducing the dependence on the experience of inspectors. The measurement efficiency is significantly improved while the personnel occupation and elevator downtime are reduced. Through using this device bracket, the verification efficiency and accuracy of the inspection about the distance between elevator car and shaft wall can be significantly improved.

Micro expression is a kind of natural human expression, which lasts for a short time and is not easy to detect. Due to the subtle spatiotemporal variation of micro-expressions, the recognition of micro-expressions is still a big challenge. Although many scholars have made some attempts in the recognition of micro-expressions, the accuracy of the recognition problem is still not ideal. In order to take advantage of 3D convolution, we propose an improved model of micro expression recognition based on 3D convolution neural network (3D-CNN). In the sequential model based on the deep learning framework of Keras, 3D convolution, pooling, batch normalization and other layers are added to construct the sequence. The recognition rate of this model on SMIC database can reach 76.92%, and it also shows good recognition rate on other databases. This method is superior to or partially superior to the classical methods and the current mainstream methods.

According to the principle of electromagnetic Acoustic transducer (EMAT), the propagation characteristics of electromagnetic ultrasonic shear wave in pipeline are analyzed by using the finite element analysis software COMSOL. Based on the study of the acoustic field characteristics of the ultrasonic shear wave, a finite element model with bubble defects was established, and the ultrasonic response characteristics of the inner and outer walls of the pipe with defects were simulated and analyzed, and compared with those of the pipe without defects. Then the simulation analysis of the defects of different sizes and different positions is carried out, and the relationship between the size, position, defect echo, defect transmission wave and time is obtained, which lays a foundation for the quantitative and location monitoring of pipeline bubble defects. The possibility of electromagnetic ultrasonic body wave in oil pipeline flaw detection is verified.

Since there are usually interference sources such as butter lamps or burning incense in typical sacrificial places, such interference sources will cause false alarms of smoke detectors, thereby reducing the reliability of fire detection and alarm. Aiming at the common fire sources and interference sources in sacrificial places, the response values of four kinds of standard test fire, butter lamp and incense burning interference sources were measured by means of infrared radiation and red & blue light scattering, which are commonly used in photoelectric smoke detection technology. Through regression analysis of response trend, the proportional function between smoke intensity and response values is revealed. Through data analysis, the fire identification method based on the intensity of smoke combustion is verified to promote the forward alarm time and anti-interference.

The determination of gas well productivity is the basis of scientific and reasonable development of gas fields and has important guiding significance for gas well production allocation. According to the change of gas-water two-phase seepage law, the productivity equation of horizontal well with gas-water production in low permeability gas reservoir was established based on the theory of steady seepage, which was affected by stress sensitivity, formation damage and high-speed non-Darcy. The results show that the effective thickness, horizontal section length, permeability and well radius are positively correlated with productivity, while the water saturation, stress sensitivity, well control radius, skin factor and formation temperature are negatively correlated, and the water saturation and stress sensitivity have a greater impact on productivity.

In view of the safety problem caused by the bubble distribution in the reactor flow passage, in order to pay attention to the characteristics of water and bubble two-phase flow in the reactor channel, the design of the array structure capacitance sensor is proposed. The three-dimensional model of array capacitance sensors is established by COMSOL Multi-physics finite element simulation software. The simulation results show that bubbles change the distribution of electric field intensity. The relationship among the distance between the polar plates, the size of the bubble and the capacitance value is studied by controlling the variable method to parameterize the scanning bubble radius, the polar plate spacing and the width of the polar plate. The simulation results show that the capacitance values decrease with the increase of bubble radius. The capacitance values decrease obviously when the bubble radius is more than 0.5mm. The capacitance values decrease with the increase of electrode spacing, and 6mm has higher sensitivity as the electrode plate spacing of capacitance sensor. the capacitance values increase with the increase of electrode width, in the range of 3-7mm, the differences between the change of capacitance values with bubbles and without bubbles are obvious, the electrode width is 5.5mm according to the sensitivity requirements of sensors.
