累积法:一般用于测量。被测量的量太小不易测量,方法是把多个相同的量集中起来测量,再除以被测量的个数。如:测细铜丝的直径、测一张邮票的质量、测1张纸的厚度等。类比法:由两个对象的某些相同或相似的性质,推断它们在其他性质上也有可能相同或相似的一种推理方法。类比得到的 Accumulation method: generally used for measurement. The amount to be measured is too small to be measured. The method is to collect a plurality of the same amount and divide it by the measured number. Such as: measuring the diameter of thin copper wire, measuring the quality of a stamp, measuring the thickness of a sheet of paper. Analogy: It is inferred from some of the same or similar properties of two objects that they are likely to be the same or similar in other properties. Analogy
