Recently, the University of Science and Technology of China Institute of Optics and Optoelectronics Engineering Key Laboratory of optoelectronics science and technology in Anhui Province, Minghai, Professor Wang Pei Micronanopatum optical and technology research group associate Professor Zhang Douguo and Energy Chemistry Collaborative Innovation Center, Chemistry and Materials Science Professor Zou Gang, Department of Macromolecular Science and Engineering, College of Science, Southwest University of Science and Technology, Dr. Chen Junxue, a professor at the University of Maryland School of Medicine, proposed a new optical mode: one-dimensional buluo existing in multi-layer dielectric film and nanofiber composite structure He surface wave (BSW-1D). Using this mode successfully solves the technical problem that the ultrafine polymer nano fiber can not transmit the optical signal on the conventional substrate. According to reports, the research team used the structural parameters of the well-designed multi-layer dielectric film-supported polymer nanofibers, with the multi-layer photonic bandgap photonic band gap to prevent optical leakage in the nanofiber. Experimental results show that very thin nanofibers can transmit optical signals on the multi-layered dielectric film. The transmission mode is the newly discovered one-dimensional Bloch surface wave, BSW-1D mode. The study is applicable to a variety of polymer nanofibers, which have good biocompatibility and can be doped with a variety of fluorophores to produce a variety of novel nanophotonics devices. Hydraulic Support System Seals
The seal of the Saifu lever hydraulic support is composed of a sealing ring, a retaining ring, a guide ring and a dustproof ring.

Hydraulic support seal
Prevent leaks. Used in the category of hydraulic supports: drum ring, composite seal, mountain ring, bud ring, O-ring, etc. Generally rubber, polyurethane material.
Used together with the sealing ring, it has the functions of anti-crowding, guiding and reducing wear. It is generally made of phenolic XII cloth, 45% copper powder mixed with filled PTFE and other materials.
Guide ring:
It is a part used on the jack piston or piston rod to support the movement of the piston or piston rod. It can prevent the piston or piston rod from direct contact and friction with the cylinder during the movement, and protect the cylinder and the piston or piston. The rod is not damaged. Generally, it is polyoxymethylene, polytetrafluoroethylene and other materials.
Dust-proof ring: the main function is to go out and reciprocate the piston rod to expose the impurities attached to the outer surface of the cylinder, so as to prevent impurities such as external dust from entering the inside of the sealing mechanism. Generally rubber, polyurethane and other materials.
