一、归一问题是用一般解题方法解答的应用题。在应用题中,归一问题所给出的条件和问题,一般涉及相关联的两种量,解题的第一步是用这两种量中相对应的一对数值,根据常见的数量关系,用“把一个数平均分成多少份、求一份是多少”的知识求商,得出暂时稳定不变的第三种量,如某一单位时间内物体运动的路程,某一物体单位体积的重量等;第二步再按同类的数量关系求出应用题的问题。由于上述特点,特别先要求出平均每份是多少,得出稳定不变的第三种量,所以,传统习惯认做典型应用题,命名为“归一”。1963年的小学算术“教学大纲”,只把归一作为“用一般解题方法解答的应用题”。这样处理,
First, the normal problem is to use the general solution to the problem of application questions. In the application problem, the conditions and problems given by the normalization problem generally relate to two related quantities. The first step in solving the problem is to use a corresponding pair of numerical values of the two kinds of quantities according to the common quantitative relationship , With “a number of evenly divided into how many copies, seeking a is how much” knowledge, come to a temporary stable third quantity, such as a unit of time the movement of objects within a unit volume of objects The weight of the second step and then the same amount of relationship between the application of the problem. Because of the above characteristics, it is particularly necessary to first ask what the average amount is and how to get the third amount that is stable. Therefore, the traditional practice is to identify the typical application title and name it “normalized.” The elementary school arithmetic “syllabus” of 1963 only regarded the normalization as “the application problem solved by the general method of solving problems”. In this way,
