href="/wiki/%E9%87%8F_(%E6%95%B0%E5%AD%A6)" title="量 (数学)">量 (數學)</a></b>」。</div> <p><b>量</b>（quantity，amount）是作为幅度和重复次数出现的一种属性；某量的大小，通常可用一个数乘以一个参照对象来一起表示，称为<b>量值</b>（magnitude，quantity value），参照对象可以是：测量单位、测量程序、标准物质、约定参考标尺。 </p><p>物理的“量”和<a href="/wiki/%E5%93%81%E8%B4%A8" title="品质">品质</a>、<a href="/wiki/%E5%AE%9E%E8%B4%A8" class="mw-redirect" title="实质">实质</a>、<a

title="关系">关系</a>一样是事物的一种基本类别。数量的概念始于份额，也就是可以带有数量的实体。作为一个基本的詞彙，数量被用于指代事物的任何量化的属性或特征。有些量由其本质决定（譬如，数），而另外一些是作為對状态的描述（属性，尺寸，特征），譬如重和轻，长和短，宽和窄，大和小，多和少。 </p><p>量的两个基本分类，<a

title="集合名詞">集合名詞</a>：<i>军队，舰队，羊群，政府，公司，聚会，人群，合唱团，数</i>。属于幅度的是连续的，可以一直分解下去，包括所有非集合名词：<i>宇宙，物质，能量，液体，材料</i>。 </p><p>和对其本质和分类的分析一起，量的问题涉及很多密切相关的课题，譬如幅度和重次的关系，<a href="/wiki/%E9%87%8F%E7%BA%B2" title="量纲">量纲</a>，<a href="/wiki/%E7%AD%89%E5%BC%8F" class="mw-redirect" title="等式">等式</a>，<a href="/wiki/%E6%AF%94%E4%BE%8B" title="比例">比例</a>，<a href="/wiki/%E6%B5%8B%E9%87%8F" class="mw-redirect
