BEIJING, Jan. 6 (Xinhua) -- The following is a summary of published science and technology news of China.

TELECOM OPTICAL FIBER

Chinese scientists have developed a new way to monitor aftershocks by using telecom optical fiber with less deployment time and cost.

A research team from the Innovation Academy for Precision Measurement Science and Technology, affiliated with the Chinese Academy of Sciences, used distributed optical fiber seismic-sensing technology to turn an urban telecom optical fiber network into an ultra-dense seismic monitoring array for a rapid post-quake response.

SPACE STATION BUILDING

China will complete the building of its space station in 2022, according to the China Aerospace Science and Technology Corporation.

The country will see 40-plus space launches in 2022, including multiple manned space flights, the company said at a recent conference on its plan for the new year.

It plans to launch two cargo craft, two Shenzhou spaceships and two laboratory modules of China's planned space station within the year.

FAST TELESCOPE

Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), also dubbed as the "China Sky Eye," scientists have obtained accurate magnetic field strength in molecular cloud, a region of the interstellar medium that seems ready to form stars.

Employing the technique of HI Narrow Self Absorption (HINSA), they achieved a clear detection of the Zeeman effect -- the splitting of a spectral line into several components of frequency in the presence of a magnetic field.
