Ion-stabilized gas nanobubbles (the so-termed "bubstons") and their clusters are investigated in bulk aqueous solutions of NaCl at different ion concentrations by four independent laser diagnostic methods. It turned out that in the range of NaCl concentration 10(-6) < C < 1 M the radius of bubston remains virtually unchanged at a value of 100 nm. Bubstons and their clusters are a thermodynamically nonequilibrium phase, which has been demonstrated in experiments with magnetic stirrer at different stirring rates. Different regimes of the bubston generation, resulting from various techniques of processing the liquid samples, were explored.
通过四种独立的激光诊断方法，在不同离子浓度的NaCl本体水溶液中研究了离子稳定的气体纳米气泡（即所谓的“气泡子”）及其聚集体。结果表明，在NaCl浓度范围10(-6) < C < 1 M内，气泡子的半径实际上保持不变，为100 nm。气泡子及其聚集体是一个热力学非平衡相，这已在不同搅拌速率下使用磁力搅拌器的实验中得到证明。探索了由处理液体样品的各种技术产生的气泡子生成的不同机制。
