Shuitu Baochi Xuebao, 2006 采用人工降雨和自然降雨的方法对紫色土坡地磷素迁移进行比较研究。研究结果表明：紫色土坡地产生地表径流和壤中流两种径流模式，壤中流其径流动态过程受降雨强度和表层作物覆盖度的影响；持续性变化的大雨强更容易引起土壤磷非点源输出，导致水体富营养化；在中到暴雨条件下，壤中流累积迁移流量低于地表径流，差幅决定于土壤表层界面（植被覆盖）特征，地表径流中的磷迁移量是壤中流迁移的3～4倍。

Shuitu Baochi Xuebao, 2021 横坡垄作是被广泛采用的保护性耕作措施之一。垄沟低洼处的积水可诱发壤中流，并可造成雨滴打击对土壤颗粒分离/搬运的增强与减弱作用并存。因此，横坡垄作坡面雨滴打击与壤中流交互作用对土壤侵蚀过程的影响有别于传统坡面。基于人工模拟降雨试验，对有/无雨滴打击作用（RI，WRI）自由入渗（FD）和壤中流（SP）2种试验处理下的产流、产沙过程进行了探究。结果表明：（1）径流量表现为SP+WRI > SP+RI > FD+RI > FD+WRI。雨滴打击作用和壤中流对径流的贡献分别为-47.09%~54.37%和41 ...

Damage to Alexandrlum tamarense DNA Caused by Hydroxyl Radicals [PDF]
, 2016 利用羟基自由基(·OH)压载水处理系统,采用大气压强电场放电技术制取·OH溶液对塔玛亚历山大藻(Alexandrlum tamarense)进行处理。通过普通光学显微镜,荧光显微镜和电子显微镜对·OH处理前后的塔玛亚历山大藻的细胞结构进行观测。结果表明,·OH能有效破坏藻细胞,从而造成藻类死亡。利用随机扩增多态性DNA(random amplification polymorphic DNA,RAPD)和实时定量PCR(RT-PCR)相结合的技术检测·OH对DNA链的破坏作用 ...
