It utilizes alkalinity potassium permanganate determination and technique of flow injection analysis.

一种新型的海水COD在线测量仪已经研制出来,其采用了碱性高锰酸钾法和流动注射分析技术,仪器的测量结果与标准方法有很好的一致性,它们的相关系数超过0.98。

The dissolubility of PPLA in water was (2.16~4.32)×10-2 mg·mL-1 according to eye judgment. The critical micelle concentration was 2.16×10-2 mg·mL-1 obtained from a fluorospectrophotometer. The self-assembled aggregates of PPLA in water were nanoscale spheres observed by a transmission electron microscope. The particle size and zeta potential tests by dynamic light scattering revealed that during preparation, the ratio of hydrophilicity/hydrophobicity, the aqueous medium and the pH had great influences; while dilution, freezing and pH change to basic condition had no effect after preparation, but pH change to acidic condition made the nanoparticles precipitate.

目测法得到其溶解度为(2.16~4.32)×10-2 mg·mL-1;荧光法得到聚合物的临界胶束浓度为1.12×10-3 mg·mL-1;透射电子显微镜观察显示该聚合物在水中的自组装聚集体为纳米级球形;动态激光光散射测试微球的粒径和Zeta电位发现,在微球的制备过程中,聚合物的亲/疏水性比例、水相介质及水溶液的pH值对它影响显著;而制备后,稀释和冷冻对它无显著影响,改变微球的环境pH值至酸性,出现聚集,至碱性无影响。

Stick with the basic black and dark gray, and...complement it with a powder - blue tie.

穿碱性黑和深灰,还要。。。配粉蓝色的领带

Methods Blood samples were collected from the precaval vein of 6 female Tibet mini-pigs to test the concentration of sex hormones including T,P4,E2,FSH,LH,PRL and blood biochemical indexes including Ca, Mg, P, ALP, Cre, CHO, TP, and Alb during the estrous cycle.

对6头雌性西藏小型猪在发情周期内的发情当天、第5天、第10天、第15天、再次发情时分别采血5 mL并分离血清,应用放射免疫法测定血清睾酮、孕酮(P4)、雌二醇(E2)、促卵泡生成激素、促黄体生成激素、泌乳素;用自动生化仪测定血清钙、镁、磷、碱性磷酸酶、肌苷、总胆固醇、总蛋白、白蛋白。

With the characterization of NMR and IR, combining with the synthesis of active species and studies of their structures, it is suggested that the hydride [RuHCl(PPh3)3], being favorably formed in the acid media, exhibited higher activity in the reduction of the C=C bond, while the hydride [RuH4(PPh3)3], being preponderantly formed in the basic media, showed activity and higher selectivity towards the C=O reduction.

通过核磁、红外等表征手段,并结合可能催化活性配合物的合成和结构研究,推测了在非水介质中对C=C和C=O双键起到活化作用的催化剂活性物种和可能的选择加氢反应机理,即,催化剂[RuCl2(PPh3)3]在酸性环境下倾向于生成[RuHCl(PPh3)3]物种,该Ru-H物种对C=C双键加氢反应表现出较高的活性;而碱性环境下则易于生成[RuH4(PPh3)3]物种,该Ru-H物种对C=O双键加氢具有较高的催化活性。
