正确答案

(1)明确目的,严格控制条件通过实验可以从复杂的现象、成份、条件及其它影响因素中,找出主要、关键的因素。排除那些与研究对象无关的偶然因素和次要因素的干扰。
(2)强化条件,深化认识自然界的事物在常态下,一般都不易暴露其特殊性质及规律,只有在一些极端条件下,某些特性和规律才得以显现出来。在实验室内,人们可以借助于各种仪器设备,制造出自然状态下(生理状态)难以出现或不能出现的环境和特殊条件。
(3)定向实验,重现原貌实验中人们不反对自然现象实行定向强化和深化,使事物的变化向指定方向发展,而且可以制造出特定的环境,使自然现象及其变化过程在实验中再现出来。
(4)便于模拟,总结规律实验室中,能将宏大的自然现象缩小进行模拟实验。如,对生命起源的模拟实验;模拟训练比赛等。
