多普勒周跳方法:数据分析Considering the limitation of Doppler detection method,an improved cycle-slip detection and repairation method is proposed for single-frequency BDS (BeiDou System) receivers.Firstly,a sliding way of fix windows is used for polynomial fitting of the initial Doppler value.Then,...
放射性元素该文讨论的两个含有核素的药物,是通过技术平台分别研制的成像诊断药和肿瘤治疗药,两个药物除放射性元素不同外,分子中的螯合片段和与受体结合的配体结构完全相同,诊断和治疗的疾病以及作用的靶标也相同,一定程度上体现了该技术平台的通用性.该核心技术的依据是胃肠道神经内分泌肿瘤具有高表达生长抑素受体(S...
套袋外观品质内在品质The effect of different bagging treatments on the fruit quality of peach cultivar Xiahui 8 was studied by using no bag-ging as the control.The results showed that bagging treatment could change the pericarpial coloration , raise sugar-acid ratio, and improve fruit flavor ....
