"laboratory experiment"(实验室实验)是指研究人员在受控环境中,通过系统化操作变量来验证科学假设的实证研究方法。这类实验具有三个核心特征:
变量控制
实验室环境允许研究者精确控制自变量(如温度、光照强度)并测量因变量变化,例如在化学实验中通过调节反应物浓度观察生成物质量。美国化学会指出,这种控制能力是实验室研究区别于自然观察的关键优势。
可重复性
标准化的操作流程确保其他研究者能复现实验结果,例如心理学领域经典的米尔格拉姆服从实验就曾在不同实验室重复验证。英国皇家学会强调可重复性是科学实验有效性的基石。
理论验证
通过隔离干扰因素,实验室实验能有效检验特定理论机制,如物理学家卡文迪什通过扭秤实验验证万有引力定律。美国国家科学基金会数据显示,约73%的基础科学突破源自实验室实验。
“Laboratory experiment”(实验室实验)指在受控的实验室环境中,通过人为操纵变量来观察现象或验证假设的科学实验方法。以下是详细解释:
受控环境
实验在封闭的实验室中进行,研究者能精准控制温度、光照、湿度等外部条件,排除无关变量干扰。
变量操纵
研究者主动改变自变量(如药物剂量、光照强度),观察因变量(如反应时间、生长速度)的变化,以验证因果关系。
可重复性
实验条件标准化,其他研究者可按相同步骤复现结果,增强结论的可靠性。
优点
局限性
