Since there are some disadvantages, such as magnitudes, reference systems and difficulties in observing an asteroid during its motion in its whole orbit, etc., when the asteroid is observed simply by means of the meridian or photograph methods, a new method for observing asteroids with a lower latitude meridian circle and a CCD measuring device is proposed according to the conditions of the geographic latitude of the Yunnan Observatory which can be used to observe the whole orbit of an asteroid.

考虑到单纯用子午方法或照相方法对小行星进行观测存在着因星等、定标星系统，以及难于在小行星运行全轨道上进行观测等方面的不利因素，在本文中，根据云南天文台能观测小行星全轨道的地理纬度条件，提出利用低纬子午环与CCD测量装置相配合，并利用低纬子午环直接提供的定标星，在一个统一的基本仪器系统中，通过对小行星在全轨道上均匀分布的观测，获得高精度的小行星观测资料，以便得到更准确的星表零点改正。

其次，采用中性蛋白酶、碱性蛋白酶等几种常用的蛋白酶对分离的7S和11S球蛋白进行酶解比较实验，发现在相同条件下，7S比11S酶解后的酸溶多肽得率高，7S比11S相对更容易被酶解；通过扫描电镜和SDS-PAGE电泳分析7S和11S的酶解产物，表明7S和11S分子酶解前后的变化明显，但两种大豆蛋白经酶解作用后，均有相当部分未被酶解的蛋白分子残留在酶解残渣中，而酶解离心后的上清液中则已基本不存在原来的蛋白质大分子。
