论文部分内容阅读
We present a wavelength-tunable narrow-band fiber-coupled source to generate correlated photon pairs at 539 nm and 1550nm. Using a 10-mm PPLN crystal, we obtain more than 50ram tunable range near 1550nm. Thissource,given its spectral property and tunable property, is well suited for tasks in fiber-optic quantum communication and cryptography networks.

高中的美术课程不同于高中其他的文化课程,它本身就是为了能让学业压力繁忙的高中生能在紧张的学习中放松下来而开设的课程。高中美术的欣赏课不怎么需要学生亲自动手去画,去实践,而主要要求学生用眼睛去观察一幅画、一件艺术作品,用眼睛去感受一幅画或者一件艺术作品其中的美。美术欣赏课的学习对每位高中生来说也是非常有必要的,作为一名教师,我们应当不断地去探索关于美术欣赏课的教学方法,不同的教学方法以及不同的教学模
