相容条件是指两个条件的关系是包含关系。如果条件A与条件B有AB,则在解题时条件A可以舍去。如果不舍去条件A,当然不会使解答产生错误,但使解答过程繁锁,方法不尽合理,运算难得简练。这种问题的产生,或是对问题的条件没有进行认真的分析和思考,粗 Compatible conditions mean that the relationship between two conditions is inclusive. If condition A and condition B have AB, condition A may be rounded off when solving the problem. If condition A is not discarded, of course, it will not cause an error in the solution, but it will make the solution process cumbersome, the method is not reasonable, and the operation is simple and concise. The emergence of this problem or the conditions of the problem has not been seriously analyzed and considered.
