During solar eclipse, the lunar shadow moves through the earth's atmosphere with supersonic speed. Chimonas and Hines deemed that the shock waves produced by cooling of atmosphere would induce gravity waves, and both TIDs and atmospheric pressure changes can be detected in the ionosphere and on the ground respectively. Although the IGW signals from solar eclipse are usually quite weak, they can still be detected .The pressure changes on ground level occur near the region of eclipse, but can be detected even far beyond the path of eclipse. This article is the first one to report results of detecting pressure waves caused by solar eclipse in China.Druing the 23rd September 1987 annular solar eclipse, IGWs have been detected and recorded at infrasound observatories in Urumqi, Taiyuan, Xuzhou and Suzhou, which are situated within the path of annular eclipse, as well as in Beijing and Guiyang, which are situated on the opposite sides of this path. The signals are detected by microbarometers of condenser microphone type. After analysing the waveforms of the recorded signals numerically, the wave periods and wave amplitudes are determined to be within the ranges from 10 to 60 min and from 7 to 20 Pa (peak to peak ) respectively. The results from dynamical spectral analyses show that the spectral distribution of all the gravity wave periods from various observatories is continuous and possesses a common main period of 40 min. Moreover, there are waves with even longer periods in different observatories and their appearance times are quite different.

脱水诱导基因(Responsive to Dehydration,rd)是一类能够调节植物脱水的基因,对植物脱水胁迫具有一定耐受性,有些成员还对低温、高盐等非生物胁迫具有不同程度的响应。rd成员分属于不同家族,在结构和功能方面存在差异。归纳不同rd的结构组成、蛋白保守基序、调控机理以及应对生物以及非生物胁迫时的功能,以及rd基因启动子区域中不同的顺式作用元件在基因应对非生物胁迫时发挥的作用,可为今后对rd基因的研究提供相关参考。
