It is understood that Zhe Shida has a Ph.D. student at the Institute of Semiconductors of the Chinese Academy of Sciences and the chief scientist of the National 863 Key Project “High-efficiency Nitride LED Materials and Chip Key Technologiesâ€. Professor Li Jingbo has established a LED chip R&D center as the core technical team.
Dongjing Electronics believes that this cooperation will help both parties to take advantage of their respective advantages and will further strengthen the company's LED sapphire wafer development and LED chip technology development.
crawler tractors are versatile,domestic initiative and technology leading. Hydraulic controlled differential - brake turn to technology , 360 degree steering wheel control and spin turn are our company`s unique advantages. In addition, our products also have the superiorities of triangular track drive, low grounding pressure and better Paddy field performance. Our company has iron crawler tractor and Rubber Crawler Tractor, which two main products. Every products have different types. These products are of high efficiency, long operating life. and low fuel consumption. Our crawler tractors are easy switching between hydraulic infinitely variable speed and mechanical transmission.
