摘　　要：ＢＬＡＺＡＲＳ天体是活动量系核ＡＧＮ（ＡｃｔｉｖｅＧａｌａｃｔｉｃＮｕｃｌｅｉｓ）的一个重要子类，是众多河外天体类型中的一类，是现代天体物理学中的重要前沿研究课题之一（被认为是现代物理学的四朵乌云之一）。我们理论与观测相结合，在观测上，我们利用北京兴隆２．１６米望远镜和云南天文台１米望远镜对这类天体中的若干样品进行了长期ＣＣＤ测光和光谱观测，新发现了近２８个ＢＬＬａｃ天体有短时标光变，新发现了１２个ＢＬＬａｃ天体、４个类星体、一个ｓｅｙｆｅｒｔ星系，在理论研究方面，我们在光变周期和辐射机制、黑洞吸积和高能ｇａｍｍａ辐射。BLAZARS object are the first object of Active Galactic Nucleis. Active Galactic Nucleis are the first object in the a lot of extragalactic object and important question for study or discussion in modern astrophysics. We have workes combine theory with observations. In a long time, we were observed with the 102cm RCC telescope at Yunnan observatory equipped with a direct CCD camera and using the 2.16m telescope of Beijing Astronomical observatory, 12 sources were found to be new BL Lac objects,4 sources were found to be new quasar, one sources was found to be new seyfert galaxy, 28 sources were found to be new shortime burst. We have new progress in the study of theory.
