    Abstract: Recently some researchers studied the frequency characteristics of a quartz crystal resonator (QCR) adhered with micro-particles to measure their physical and geometric parameters. Many researchers regard the particles as rigid spheres or consider the elasticity but ignore the contact deformation and contact area of the particles. In fact, the adhesion and vibration of soft particles are coupled together and the interaction is strong and complicated. In this paper, we separately simulated the adhesion and vibration of the particles using finite element method with ANSYS software. Through transmission line model of the QCR, we get the frequency shift induced by surface particles. We found larger, softer and heavier particles produce greater contact deformation and load impedance which cause greater frequency shift (negative). The obtained results can be applied into characterization of size and elastic modulus of micro-particulates.

    Abstract: At present, 5G refers to a vital direction for evolving and upgrading new generations of information technology, and the Industrial Internet critically supports the fourth industrial revolution. 5G has acted as a novel driving force to lead the innovation and stimulate the novel types of information. From a technical perspective, in the 5G field, ultra-low-loss high-reliability copper-clad laminate materials employed in 5G high-speed communications (56Gbps, 112Gbps), 5G metamaterials and low-loss high-performance RF technology, and 5G low-loss magnetoelectric functions. For materials and devices, multi-module integrated printed circuits for 5G communication base stations, manufacturing of 5G communication optoelectronic integrated cables, and multi-channel high linearity and large dynamic range RF optical transceiver integrated modules in terms of 5G mobile communication will show critical significance, as well as in smart agriculture application and demonstration. From an application perspective, China has made it clear that it will start 5G commercial use in 2020, and has issued 5G licenses ahead of this year, which is also leading in the world. 5G fully complies with the future trends of human progress, social development and economic growth. Inevitably, its large-scale applications will be achieved and will expand to a wide range of industries and fields, extended to all aspects of the economy and society, alter human consumption patterns, and transform human production, which can provide a powerful means for the high-quality development and governance of society.

    Abstract: A dynamo is necessary for reversed field pinch (RFP) configuration sustainment in a continuous way or oscillation cycles by self-organization. A dynamo velocity field from electrostatic drift is studied in three-dimensional (3D) equilibrium for Keda Torus eXperiment RFP plasmas in quasi-multi-helical (QMH) and quasi-single-helical (QSH) states. The 3D equilibrium reconstruction is computed by VMEC code. It is found that the electrostatic potential provides helical modulation of plasma flow in QSH states. The electrostatic potential in QMH states is processed as a superposition of limited helical harmonics, and it shows an axisymmetric pattern. Non-axisymmetric components are negligible in QMH states because of flux surface averaging of the electrostatic field and corresponding electrostatic drift flow. The electrostatic drift velocity is comparable to the total plasma drift in QSH states; this implies that the electrostatic drift may play an important role in sustaining the helical configuration in RFP plasma.

    Abstract: At present, the auxiliary ships for inland waterway operations mainly use diesel as fuel, and a large amount of polluting gas is emitted in the inland waterway, which seriously affects the air quality of cities along the waterway. In order to solve the impact of the current inland waterway auxiliary ships on the environment, this work has designed a new energy intelligent pusher for inland rivers and lakes. The pusher uses electric energy as an energy source. This work is mainly composed of power supply system, container battery rapid replacement system, ship slow contact system, ship positioning and anti-collision system. Under the joint cooperation of all systems, the intelligent jacking of inland rivers and lakes and the rapid battery replacement are completed, and finally it is green, Intelligent and efficient operation effect.
