Abstract:	本文欲探討，在已知一枚硬幣重量有誤而其他硬幣重量皆相同的情況之下，利用無砝碼天平秤n次，最多可以從多少枚硬幣中找到重量有誤的那一枚硬幣並且知道是較輕還是較重。第二章分別討論「已知一枚硬幣較重」、「已知一枚硬幣較輕」和「已知一枚硬幣重量有誤但不知道是較輕還是較重」三種情況，利用決策樹和數學歸納法證明之，第三章給予實際操作的過程。 This article wants to find : under the condition that one coin is wrong in weight and the other coins are the same weight, using a scale without weight, what is the maximum number of coins that we can find from the coin with the wrong weight ,and know that it is heavier or lighter ? In chapter 2, we will discuss the following three cases : there is a heavier coin, there is a lighter coin, and there is a coin of wrong weight but not sure the coin is heavier or lighter, separately. we will use the decision tree and mathematical induction to prove them. In chapter 3, we will show the practical process.
