Effect of potassium nutrition on photosynthetic characteristics of small Cushaw [PDF]
, 2005 利用CIRAS-2型便携式光合测定系统,研究不同钾素营养水平下小南瓜的光合特性。结果表明：小南瓜叶片的蒸腾速率、气孔导度、净光合速率的日变化与钾素营养之间呈显著的正相关(r值分别为0.965 1、0.816 0、0.926 9),细胞间隙中C0_2浓度日变化与钾素营养之间呈显著的负相关(r=0.847 9)。The photosynthetic characteristics of small Cushaw at different potassium levels was measured by ...

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.
