The results of differential scanning calorimetry ( DSC) showed that the decomposition temperature of ACPA decreased when it was chelated onto the particles. 差热扫描量热分析表明偶氮引发剂与纳米碳酸钙螯合后分解温度略有降低;
Alternating notch periodogram algorithm ( ACPA) based on maximum likelihood ( ML) can regarded as a complete solution to the discrete spectrum estimation problem since it achieves superresolution, very high accuracy, and low SNR threshold. 基于最大似然法的交替陷波周期图算法(ANPA)是一种超分辨率的谱估计算法,它同时具有超分辨率、高精度和低信噪比门限的特性。
