[Objective]To evaluate the effect of device of piping drinking water by surveying the changes of piping drinking water bstween the first used and period of time used.[Method]According to the relative standard of our country,piping drinking water is detected from 10 districts that are selected from previous data.[Result] There is significant difference between the first used and period of time used with hydrogen ion,turbidity,COD (P＜0.05).There is apparent significance from different cleansing principle with hydrogen ion,COD,rigidity (P＜0.05).There is no significance of different devices with time used in hydrogen ion,rigidity,COD, conductance and rigidity.(P＞0.05).[Conclusions]After a period of ruing of current piping drinking water device,the water qualifies of piping drinking water have no apparent ***,the possibility of secondary pollution still exists in the pipeline.

简述了利用植物油和甲醇在催化剂NaOH的作用下进行酯交换反应制取生物柴油的基本原理和操作方法。并研究了影响反应产率的各种因素,得出了制取生物柴油的最佳反应条件是催化剂的用量为油量的1.0 % (质量分数) ,反应时间为4 0～5 0min ,油醇摩尔比为1∶6 ,此条件下反应产率最高,可以达到87%。生物柴油和0 # 柴油的性质非常相似,因此它能直接被应用到发动机上而不需要改动发动机的结构。在柴油中掺入不同比例生物柴油的混合燃料,柴油机的CO、HC和烟度均有较大的降低,NOx 的排放略有升高,耗油率基本不变。

Genetically encoded Ca indicators(GECI)are important tools that enable the measurement of Ca dynamics for tissues and organs in a physiologically context. GCaMP2 as a widely used GECI has been iteratively improved in recent years. Among these improved variants,GCaMP3 has much better properties in terms of protein stability,signal-to-noise ratio and calcium affinity compared to *** recently developed a better GCaMP3-based new generation GECI,G-CaMP5,and systemically investigated its properties under difierent *** results suggest that our new GECI has been improved a lot in many aspects compared with G-CaMP3.
