An unified approach for designing and teaching of latch, monostable circuit and multivibrator(基本触发器、单稳态电路及多谐振荡器的统一设计和教学方法研究)

Zhejiang Daxue xuebao. Lixue ban, 2022
针对一般教科书缺乏对基本触发器、单稳态电路及多谐振荡器设计方法的论述问题，从电路存储信号需求出发，研究了基本触发器、单稳态电路及多谐振荡器间的内在联系，发现通过在基本触发器的支路中接入电容，由电容的充放电实现单稳态电路及多谐振荡器，从而提出了基本触发器、单稳态电路及多谐振荡器的统一设计方法，并在课堂上讲授。这不仅有利于学生学习和掌握这3种电路的设计方法，深入理解这3种电路的工作原理，而且可培养学生探索事物本质及其内在联系的能力。

White‐Light Flexible Crystal With 180° Folding Induced by Halogen‐Bond Network in Organic‐Inorganic Hybrid Perovskite

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Organic‐inorganic hybrid perovskites (OIHPs) with white‐light emission have significant potential in solid‐state lighting and display due to the designable structure and excellent luminescent properties. However, OIHPs are prone to damage during bending due to the brittleness of crystals, which limits their application in the field of flexible

用于防雷器带电试验组合波发生器电路参数的理论计算

Gaoya dianqi, 2006
组合波信号发生器（CWG）主要用于浪涌保护器或电子设备电磁兼容试验,要求在虚拟阻抗Z为2Ω的情况下,输出1.2/50μs开路电压波或8/20μs短路电流波。基于电路微分方程的方法对CWG等效电路进行数学计算,导出相应的数学关系,给出一套计算图表。对电路参数计算结果进行电路仿真,并将计算结果应用于实际CWG电路设计。同CWG标准参数要求比对,仿真结果最大偏差小于6%;实际设计的CWG参数最大偏差小于8%。结果表明,针对CWG电路参数的计算采用的方法是正确的,计算结果可以应用于CWG设计中电路参数的选取。
