A simulation system for intertidal zone environment that can be remotely monitored is proposed. The system is divided into the two parts of remote control center and environment simulator, which are interconnected through wireless network technology. The remote control center performs remote monitoring through upper machine software, while the environment simulator can simulate natural environments such as ocean tides, water temperature and light illumination in different types of intertidal zones. Users can change and access the environmental parameters and data of the environment simulator by making instructions at the remote control center. A stable system is realized in accordance with the design requirements, and actual tests show that main features of the simulated natural environment in intertidal zones are very close to actual environment.

In this paper, Using CSMC 0.5μm CMOS process to design each sub-module, the circuit simulation, and adjustment and validation of parameters have been carried out by simulation tools. The low static power and high conversion efficiency charge pump LED driver circuit has been designed. The circuits nucleus module is adaptive charge pump (1x/1.5x/2x charge pump), to converse a wider range of input voltage to a constant output voltage with high efficiency. This circuit only needs some external capacitors, and dont need inductor. So it reduces EMI electromagnetic interference and application cost, etc.

Titanium carbonitride (TiCN) films were deposited on AZ31 magnesium alloy by radio frequency magnetron sputtering. The surface morphology and microstructure were investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD), and the corrosion resistance was studied by potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS). The results show that TiCN coatings deposited on AZ31 magnesium alloy are amorphous, and reveal good adhesion onto the substrate. The corrosion current density of TiCN-coated magnesium alloy was 1.664×10-6 A/cm2, which decreased by more than one order of magnitude compared to the uncoated magnesium alloy (1.785×10-5 A/cm2).

In recent years, the economy grows rapidly in Jilin province, and people’s life improves steadily, but at the same time, people has to face a sever employment situation. The changes on trend and characteristics of employment elasticity become flexible and fuzzy to predict with the development of society. By using linear regression methodology, employment situation of Jilin province is analyzed by taking primary industry employment elasticity, secondary industry employment elasticity, and tertiary industry employment elasticity into account. The calculation results show that three strata of industry employment elasticity has an increasing trend, and the total elasticity of employment is mainly driven by the second and tertiary industries.
