Soil washing/flushing of contaminated soil:A review

Shengtaixue zazhi (2011)

Yushuang Li HU Xiao-jun Sun Tieheng Hou Yongxia Xueying Song

Soil washing/flushing is an efficient technology for rapid remediation of soils or sediments highly contaminated by heavy metals and/or organic pollutants.In this paper,the characteristics,technical processes,and cleaning agents for soil washing/flushing remediation were reviewed.The ex-site soil washing has broad application prospects,due to its stable remediation efficiency,easy control,and waste reduction.Environment-friendly cleaning agents,such as natural chelating agents and bio-surfactants,have gradually replaced artificial chelating agents and chemical surfactants,and become the main cleaning agents for soil washing/flushing.Modern supramolecular chemistry will have significance in the washing/flushing remediation of soils contaminated by combined pollutants.

On advanced configuration enhance adaptive system optimization

Quanxin Ding Hongliang Chen Liu Hua Helong Wang Chunjie Guo

For aim to find an effective method to structure to enhance these adaptive system with some complex function and look forward to establish an universally applicable solution in prototype and optimization. As the most attractive component in adaptive system, wave front corrector is constrained by some conventional technique and components, such as polarization dependence and narrow working waveband. Advanced configuration based on a polarized beam split can optimized energy splitting method used to overcome these problems effective. With the global algorithm, the bandwidth has been amplified by more than five times as compared with that of traditional ones. Simulation results show that the system can meet the application requirements in MTF and other related criteria. Compared with the conventional design, the system has reduced in volume and weight significantly. Therefore, the determining factors are the prototype selection and the system configuration, Results show their effectiveness.

Eight-Channel LAN WDM (De)Multiplexer Based on Cascaded Mach–Zehnder Interferometer on SOI for 400GbE

Photonics (2022)

Zhizun Zhao Zhen Li Jiaqi Niu Gaolu Zhang Hongliang Chen

In this paper, we design and experimentally demonstrate an eight-channel cascaded Mach–Zehnder interferometer (MZI) based Local Area Network (LAN) Wavelength Division Multiplexing (WDM) (de)multiplexerwith channel spacing of 800 GHz on a silicon-on-insulator. By cascading a three-stage MZI, eight target wavelengths are (de)multiplexed. The length difference of the third-stage MZI delay arms is adjusted so that the output channels skip the guard band. In order to keep the central wavelength of each channel from shifting, we utilize a wide waveguide for the phase delay arm in MZI to achieve large fabrication tolerance, and the multi-mode interference (MMI) couplers as power splitters with weak dispersions. The measurement results of the fabricated device show the precise wavelength alignment over the whole working wavelength range.

The Pressure Control of High-pressure Tubing

IOP Conference Series Earth and Environmental Science (2021)

Hongliang Chen

Abstract This article mainly studies the pressure control of high-pressure tubing. Based on the theoretical basis of the pressure formula, a pressure variation model based on the pressure formula is established and solved by the enumeration method within the range. In the process of solving the model of the open time of the one-way valve in the problem, first, establish a model of the pressure change of the inlet and outlet oil. Using integral thinking, we get the oil density under each pressure. Based on the tubing pressure requirements in the corresponding time period together with the relationship between the net mass of the inlet and outlet oil per unit time, the relationship between the opening time of the inlet valve and the pressure is obtained by using the principle of the inlet valve opening time to control the inlet mass. The results of the corresponding pressure requirements are obtained through the enumeration method within the range.

Design of Transfer Alignment Scheme for Opto-electronic Platform

Journal of Projectiles.Rockets.Missiles and Guidance (2011)

Hongliang Chen

In order to meet the requirements of high precision and long time attitude measurements of opto-electronic platform in aircraft,a transfer alignment on moving base scheme for the master and slaver inertial navigation system was designed.The Scheme was based on the velocity matching plus heading matching mode.And the longtime transfer alignment Kalman filter based on feedback correction mode was designed.Meanwhile an effective data synchronization method was proposed.The simulation results show preliminarily that the misalignment vector precision is at the advantage of 0.1°under the free flight maneuver condition in 1800 seconds.Those prove that this system is effective and practical.

Calibration method of SOC characteristics of spacecraft battery pack simulator

Zhang Ruo-lin Nan Zhou Hongliang Chen

A significant parameter of the spacecraft battery pack simulator is the state of charge (SOC) parameter, which is one of the parameters that users are most concerned about during the use of the spacecraft battery pack simulator. Other parameters of the spacecraft battery pack simulator, such as terminal voltage, current, pressure, temperature, etc., are always given together with the value of the state of charge (SOC) in which they are located. The battery SOC parameter is a process quantity, and only one SOC estimation value can be obtained. In the battery simulation, the simulator gives the time-varying SOC value during the charging and discharging process according to the initial SOC state, charging and discharging conditions. Therefore, the time-varying SOC value given by the battery pack simulator must be accurately calibrated to ensure the accuracy of the battery pack simulator SOC change.

Linear MIMO transceiver optimization for minimizing the MSE with joint power constraints

Chinese Control Conference (2013)

Jisheng Dai Min Fang Hongliang Chen Bing Wan

This paper considers linear precoder optimization problems for minimizing the mean-square error (MSE) with multiple-input multiple-output (MIMO) systems. In contrast to the conventional sum-power constraint on transmit antennas, a more realistic power constraint, which is the joint constraint of sum-power and maximum eigenvalue, are adopted in this paper. Mining the internal property of the eigenvalue-decomposition of power matrix, we give an exact closed-form of eigenmode and then propose a two-dimensional searching method for deriving eigenvalues. As the number of points that needs to be searched in each dimension is less than the number of transmitters, the computational complexity of the proposed method is very low. Moreover, compared to the lp-norm method, another advantage of the proposed method is that it can achieve the global optimal solution rather than a sub-optimal one.
