After ten years of research, Chinese Professor Gao Houxiu from Tianjin University has made an important discovery that under electron microscope some domains of yuhua ("raining flowers" ) stone are found oscillating in three-dimensional directions like running liquid which sometimes appear, sometimes vanish and sometimes circumrotate. This is the first discovery of its kind ever made as a significant achievement in human's cognition of the physical world. And experts have authenticated that this discovery has been at the world advanced level at the conference on "Principle and Application of Liquid Solid" held in Tianjin University on October 25.

According to experts present at the conference, Professor Gao has observed the same phenomena on surfaces of such common solid materials as copper, aluminum, steel, cast alloy iron, composite material, yuhua stone, crystal, marble and the like. And Professor Gao has kept a record of her tests in photos and videos, made determinations of the hardness and expansion curve, and finally got a clear analysis map of X-ray diffraction hence successfully with a wealth of evidence authenticated the said phenomenon.

Experts and scholars from the Ministry of Science and Technology, Ministry of Education, the State Bureau of Seismology, and the Chinese Academy of Sciences, all spoke highly of the discovery Gao made at the conference. According to experts, the phenomenon Gao found truly exists in solid and it is still an unknown non-linear oscillation of solid. This discovery will help people to know things further in the physical world. And to furnish medium- and short-term earthquake forecast on the basis of this discovery is of no small significance to human's life.

In addition, Gao's discovery opens wide prospects for men in developing sensor, magnetic storage media, microelectronics and photoelectron, intellective materials and suchlike fields, experts said.
