Results The CaCl2 hollow stent could not only support the cannel of vascular, but also generate two membrane in the two side of anastomosis site. Thus the thickness of sealant was increased. It was effective to prevent leaking of cyanoacrylate glue and its toxicity.

结果：CaCl2中空支架不仅在血管吻合中支持血管，而且可以双面成膜，增加密封厚度，加强密封效果，能够有效阻隔医用胶对吻合口和管壁的毒性作用。

Based on the original production process, the developed corrosion inhibitor used for polyurethane foaming changes the pH of dialyzate, which is produced from submerging polyurethane foam to water, from acidity into faint alkalinity, so as to inhibit or retard corrosion of the pipeline.

研制成的聚氨酯泡沫用缓蚀剂，在不改变原有生产工艺及发泡参数的基础上，将聚氨酯泡沫浸水析出液的pH值由酸性改变为弱碱性，从而达到抑制或延缓泡夹管腐蚀的目的；采用喷涂聚脉补口技术，有效地提高了现场补口的质量。

Either sodium picrate, which is converted to sodium isopurpurate, or a freshly prepared solution of guaiacum resin in absolute alcohol which is allowed to dry on the paper and treated with very dilute copper sulphate solution. The latter test-paper turns blue with prussic

acid。苦味酸钠试验：将生药研碎，取0.5g放入试管中，加数滴水润湿，加塞密闭，管口内悬挂一条用碳酸钠溶液润湿的苦味酸试纸，将试管置40～50℃水浴进行酶解，试纸转为砖红色，若是悬挂联苯胺-硫酸铜试纸，则应生成联苯胺氧化物而使试纸变蓝色。
