Zhongguo shiyan zhenduanxue, 2008 目的探讨肝素抗凝剂对化学发光法测定HCG的影响,以验证是否可用肝素抗凝血进行检测来缩短检测时间。方法用肝素抗凝和普通真空采血管抽取20份患者标本进行对比测定,同时用高于抗凝管10倍浓度的肝素抗凝剂对20份样本中的高中低浓度的HCG样本进行干扰试验。结果肝素抗凝和普通真空采血管两组数据经配对资料t检验（P>0.05）,差异无显著性;高浓度肝素抗凝剂对高、中、低浓度的HCG干扰值均小于干扰试验对照组1.96s,最大干扰百分比不足0.9%。结论肝素抗凝剂对化学发光法测定HCG无影响,可用肝素抗凝血样进行检测。

Jianzhu Gangjiegou Jinzhan, 2023 进行了6个不锈钢管混凝土试件的纯弯试验研究，分析了弯曲荷载作用下混凝土类型和截面形状对新型S36950奥氏体不锈钢管混凝土构件破坏模态、荷载-变形关系、抗弯刚度与承载力的影响规律。试验结果表明：固废混凝土对新型不锈钢管混凝土纯弯构件的整体破坏模态影响不大，但固废混凝土对构件抗弯承载力的提升与刚度的改善有积极作用。随后建立了不锈钢管固废混凝土纯弯构件有限元模型并验证既有材料模型的适用性，最后分析了各规范抗弯承载力计算方法的适用性和预测精度。
