3.初始化时间,根据我们训练的参数,需要模拟0~pi/2范围内任意数量的时间点(本案例中使用201个时间点。 4.推理模型时。每次循环将某一个时间点复制256份,和所有的256个位置点组成2*256的二维数组,然后转置成256*2的数组,输入至网络中。 5.获取输出。输出为256*2,但和输入的意义不同:其中第0列为波函数h的实...
The second and fourth harmonics of a cw Q-switched Nd:YLF laser (Spectra-Physics TFR, 5 ns pulse width, 100 Hz-1 kHz repetition rate, 200 mW at 523 nm, 50 mW at 262 nm) are used for medium- to high-repetition-rate photoexcitation. The second harmonic o f a cw Q-switched Nd:...

2.塑料微粒分析的问题 为了区分这些塑料微粒,目前的策略是使用立体显微镜,并乏味地将塑料微粒和其他材料分开,或者使用光谱仪。遗憾的是,由于塑料微粒尺寸极小 (< 1 mm),以及人为错误和样品污染的可能性,这种可视方法容易出错。这种几乎不可能和耗时的鉴定过...
