为探究生物絮团（BFT）系统中泡沫体积与生物絮团及环境因子的关系，以求通过泡沫体积判断生物絮团的运行情况。实验采用3组凡纳滨对虾生物絮团养殖系统进行100 d的实验研究，测定泡沫体积、水体表面张力及水环境因子等参数，选用Pearson相关系数进行相关性分析，研究泡沫体积变化与生物絮团、环境因子之间的关系。结果显示，泡沫体积与总氨氮（TAN）呈现较强的正相关性，相关系数为0.571。泡沫体积受生物絮团状况影响，与絮团体积（FV）呈负相关性，相关系数为-0.266。泡沫体积由增转降的日期与生物絮团开始形成的日期高度拟合，二者相差在5 d内。随着生物絮团的形成，泡沫体积逐渐降低。当生物絮团成熟稳定时，泡沫体积会维持在0.011 0 m3/t以下（1 t水体生成0.011 0m3泡沫）。研究表明，可以通过泡沫体积的变化判断生物絮团的运行情况。本研究可提高生物絮团的可控性，对凡纳滨对虾生物絮团养殖技术的推广具有重要的指导意义。

资本与数字技术紧密结合,共同塑造了崭新的数字劳动模式,为社会和经济带来了深刻的变革,数字劳动正在成为人类生产活动的全新范式。数字资本主义背景下,数据的私有化是数字劳动剥削的基础,数字平台的规则演变成数字劳动隐性剥削的工具。数字劳动并未从资本剥削的困境中解脱出来,剥削范围趋于扩大,剥削方式更加隐蔽,剥削时间不断延长。因此,只有当数字劳动者意识觉醒,坚持在数字空间内公开透明地处理数据,才能超越资本逻辑,更好地发挥数字技术效能,彰显数字劳动的价值。
