在教学实践中,应对苏科版初中物理3个教材实验与两个传统实验设计存在的不易操作等问题进行探究,并依据教学实践提出相应的改进措施.通过实验改进实践与反思可知,实验改进应
The fractal expressions for flow rate and hydraulic conductivity for power-law fluids in a single capillary are derived based on the fxactal nature of tortuous
A new mechanism of intersection formed by two line defect photonic crystal (PC) waveguides are numerically investigated using the finite-difference time-domain
An organic dye salt trans-4-[p-(N-hydroxyethy1-N-methylamino)styryl]-N-methylpyridinium iodide (ASPI) is doped with an electron transport organic molecule tris(
农村学校设备条件有限,全靠实验室中的仪器设备来完成实验教学是不现实的.学生钢尺除了用来测量物体长度与作图外,还可用于力学实验、声学实验、光学实验等相关实验,利用学生
We present a broadly tunable active mode-locked fibre ring laser based on a semiconductor optical amplifier (SOA), with forward injection optical pulses. The la
The coupling between magnetism and structural distortions in BiFeO3 (BFO) is investigated using density functional theory by considering the spin-orbit effect.C
