由于事物普遍联系的规律的作用,犯罪行为、民事纠纷和违反行政法规的活动,在其实施和发展过程中,必然会对周围的事物产生一定的影响,留下某些痕迹。即使有人毁灭,伪造证据,其毁灭伪造证据行为又会留下新的痕迹。那些受到犯罪行为,民事纠纷或者行政纠纷发生过程中的影响而在形状、位置等方面发生变化的物品,就储存了有关案件实际情况的信息,从而可以成为证据。在大多数案件中都是可以收集到物证的,因而它是司法工作中经常使用的证据种类之一。 Due to the function of the law of universal connection of things, criminal activities, civil disputes and activities in violation of administrative laws and regulations, their implementation and development will inevitably have some impact on the surrounding things, leaving some traces. Even if some people destroy and forge evidence, their acts of destruction and forgery will leave new traces. Those items that have been changed in shape, location, etc. by criminal acts, civil disputes or administrative disputes, store information about the actual situation of the case and become evidence. In most cases, material evidence can be collected and therefore it is one of the most frequently used types of evidence in judicial work.
