A characteristic feature of weak impacts is the non-monotonic response of living organisms and model biological systems to monotonically decreasing impacts. The qualitative similarity of the effects caused by the different acting factors makes one think about the common cause of the observed effects, which is water. A comprehensive analysis of the actual composition of water indicates that water under normal conditions is a multicomponent open non-equilibrium system. Nanobubbles that are always present in water play a significant role in the properties of dilute aqueous solutions. When collapsed, they can produce active oxygen and nitrogen species that have a strong effect on biological systems. Significant non-monotonic changes in electrical conductivity found in a series of sequentially diluted solutions subjected to vigorous shaking after each dilution convincingly demonstrate the presence of chemical changes in the composition of aqueous solutions explained by mechanochemical processes. Similar changes were observed in water samples prepared in the same manner with vigorous shaking and dilution without the addition of any chemical compounds. The long-term evolution of the conductivity of such solutions depends on the chemical structure of the solutes.
弱冲击的一个特征是生物体和模型生物系统对单调递减冲击的非单调响应。不同作用因素所产生效应的定性相似性让人思考所观察到的效应的共同原因，即水。对水的实际成分进行的综合分析表明，正常条件下的水是一个多组分开放非平衡系统。水中始终存在的纳米气泡在稀水溶液的性质中起着重要作用。当纳米气泡破裂时，它们会产生对生物系统有强烈影响的活性氧和氮物种。在每次稀释后剧烈摇晃的一系列顺序稀释溶液中发现的电导率显著非单调变化，令人信服地证明了机械化学过程所解释的水溶液成分中的化学变化。在以相同方式剧烈摇晃和稀释且不添加任何化合物的水样中也观察到了类似变化。此类溶液电导率的长期演变取决于溶质的化学结构。
