A new multispectral image fusion method based on intensity-hue-saturation (IHS) transform and three-channel non-separable wavelets whose dilation matrix is [2,1;–1,1] is proposed. The multi-resolution decompositions of the intensity of multispectral image
采用脉冲激光沉积法（PLD）在Al2O3衬底上成功制备了Zn0.99Fe0.01O薄膜，研究了退火氧压对Zn0.99Fe0.01O薄膜的晶体结构及其激光感生电压（LIV）效应的影响。X射线衍射仪分析结果表明，Zn0.99Fe0.01O具有六角纤锌矿结构，并且是沿［001］取向近外延生长。同时随着退火氧压的增大，薄膜的晶粒尺寸先增大后减小，退火氧压为2000 Pa时薄膜晶粒尺寸最大，结晶质量最好。另外在10°倾斜的Al2O3单晶衬底上制备的Zn0.99Fe0.01O薄膜在3000 Pa的退火氧压下可以观察到

CHARACTERIZING FLUORESCENCE LIFETIME OF NAD(P)H IN HUMAN LEUKEMIC MYELOID CELLS AND MONONUCLEAR CELL
The aim of this ex vivo study was to explore the potential of using the fluorescence lifetime of intracellular reduced nicotinamide adenine dinucleotide (phosphate) (NAD(P)H) as a label-free indicator to characterize the differences between human leukemic
从理论上提出了一种由黑磷/介质多层结构包覆的等离子体波导。利用MATLAB数值求解该波导的色散方程，进而仿真出波导的有效折射率、传播长度、趋肤深度及品质因数等性能参数曲线。由仿真曲线可知，波导的性能与黑磷/介质多层结构中的电子掺杂率正相关，与单元层中介质层厚度负相关。与同类型金属/介质多层结构波导的性能比较后可知，黑磷/介质多层结构波导在中红外及远红外波段具更大的传播长度、更小的趋肤深度及更大的品质因数。该波导可调谐且性能优良。
