在水生与气生状态下石莼光合作用对光照和温度的响应(英文) [PDF]
, 2003 如何对付由于高潮时的水生状态与低潮时的气生状态高频率循环所导致的不同环境条件 ,是潮间带海藻的光合作用所面临的独特问题。对采自汕头沿岸的石莼 (Ulvalactuca)在水生和气生不同状态下光合作用对光照和温度的响应特性进行了测定 ,以探讨这种常见的潮间带绿藻在潮汐循环背景下的光合特性。在气生状态下 ,光饱和净光合速率 (Pmax)随气生暴露时间的变化模式可以很好地用三次方程进行描述 ,而温度影响方程的系数 ;当水分损失为 1 5 %时 ,石莼的Pmax增加至最大值 ,然后Pmax随进一步脱水而下降 ,

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

Photosynthetic capacity of three common species of macroalgae and the application in coral aquarium [PDF]
, 2014 利用水下饱和脉冲调制叶绿素荧光仪(dIVIng-PAM)测定了珊瑚养殖水处理中3种常见大型海藻石莼(ulVA lACTuCA)、条浒苔(EnTErOMOrPHA ClATHrATA)和羽状蕨藻(CAulErPA MEXICAnA)光能转化效率(fV/fM),快速光曲线(rlC)相关参数和非光化学淬灭(nPQ)。结果表明:石莼和条浒苔的fV/fM分别为0.808±0.004和0.816±0.009,显著高于羽状蕨藻。最大相对电子传递速率rETrMAX(17.52±2.92和19.59±4.43μMOl E·

A modeling study of hypoxia in the bottom layers off the Changjiang Estuary in summer [PDF]
, 2016 近几十年来，受人类活动影响，大量有机污染物和营养物质经河流排放到长江口及其近岸海域，造成水体富营养化日益严重，致使长江口外近岸底层水体缺氧现象也呈不断上升趋势。长江口底层水体缺氧的形成是个复杂的过程，是物理过程和生化过程综合作用的结果。物理过程主要控制着溶解氧的水平和垂直输运，生化过程控制着溶解氧的产生和消耗。 近年来已有许多学者研究长江口水体缺氧现象，但目前针对该区域缺氧的研究主要局限于定性的观测分析。为了更好研究长江口水体缺氧的形成机制，本文应用一个三维水动力¬-生态耦合模式 ...
