BEIJING, Sept. 18 (Xinhua) -- The following is a summary of published science and technology news of China.

PAIN RELIEVER

A new Chinese drug to alleviate patients' neuropathic pain, or nerve pain, has entered clinical trials.

The pain reliever SR419 was developed by scientists from the Chinese Academy of Sciences (CAS) and Shanghai SIMR Biotechnology Co., Ltd.

Preclinical data show that SR419 has a strong analgesic effect and no side effects, with the potential to become the world's first analgesic drug for specific targets.

MARINE MONITORING

Chinese scientists have developed online monitoring instruments for marine biological surveys and tested them in the Bohai Sea and Yellow Sea.

These instruments, installed in a monitoring ship which has travelled more than 806 nautical miles, have conducted online monitoring for more than 130 hours and collected more than 9,200 profiles of data in typical sea areas.

TRAIN MOTOR

China has developed a permanent magnet traction motor for trains with speeds up to 400 kph. The newly-developed TQ-800 motor is expected to be used in a multinational interconnected high-speed train project.

The successful development of the motor breaks the monopoly of foreign technologies in this area and lays a solid foundation for the upgrade of rail transit technologies in China.

MAGLEV TRAIN

CRRC Zhuzhou Locomotive Co., Ltd. unveiled the key components of its magnetic-levitation train with a designed speed of 600 kph in central China's Hunan Province.

Key parts of the train's power system, including a long stator linear motor and two transformers, were unveiled in the city of Zhuzhou.

The long stator linear motor plays the role of the "heart" of the high-speed train, and the transformers provide a constant and stable direct current power for the linear motor, equivalent to a "blood supply system." Enditem
