目的分析临床医学检验期间质量控制提升的主要影响因素,并提出有关干预措施。方法选择2021年1月至2022年5月洛阳白马医院检验科收集的98例患者的98份血液检验样本进行研究,对所有血液样本开展临床医学检验,后依据血液检验样本是否合格分成合格组、不合格组。比较两组的各项资料差异,将差异资料带入Logistic回归方程计算,得出临床医学检验期间质量控制提升的主要影响因素,后提出有关干预措施。结果98份血液检验样本内,有10份血液检验样本不合格划分到不合格组,占比为10.20%;余下88份血液检验样本合格划分到合格组,占比为89.80%。合格组和不合格组在患者性别、年龄及分离胶管方面,差异无统计学意义(P>0.05),但在患者有无规范准备、医务人员有无操作不当、采血部位、采血量、离心次数、标本放置时间、抗凝剂用量、pH值及温度等方面差异有统计学意义(P1。结论影响临床医学检验期间质量控制提升的因素较多,主要包含患者准备、医务人员操作、采血部位、采血量、离心次数、标本放置时间、抗凝剂用量、pH值及温度等。因此,医院需要制定出临床医学检验质量控制标准,要求有关工作人员严格按照质量控制标本规范操作,以最大程度降低不合格率,提升临床检验准确度。

由于载流子在3个维度受到量子限制,半导体量子点具有类似于原子的分立能级,并展现出许多独特的光学和电学性能.实验研制了InAs/GaAs量子点半导体激光器,分别采用傅里叶级数展开方法和Hakki-Paoli方法准确地测量和表征量子点激光器的模式增益,分析了其增益与损耗.实验结果表明HakkiPaoli方法受测量系统分辨率影响大,在增益谱峰值附近由其得到的增益明显偏低.采用傅里叶级数展开方法并由测试系统响应函数进行修正,可以获得更准确的增益谱.
