2.
In order to provide the scientific basis of preventing soils from degradation and promoting agriculture sustainable development,soil respiration,enzyme activities,soil pH and EC were studied in the greenhouse vegetable(tomato) soils under different continuous cropping times(1,5,8 and 12 year) in Shouguang,Shandong with the open field soil as control.
土壤pH随连作年限增加逐渐下降,而EC逐渐增加,至12年棚龄时,与对照相比,0—20cm土层pH下降了1。

5) SA-213 T91
SA-213T91
6) SA-178A steel
SA-178A
1.
According to the results of visual examination,chemical analysis,metallographic examination,scanning electronic microscope examination and corrosion products analysis,it is concluded that the main reason of the bursting failure of waste heat boiler pipes of SA-178A steel is heavy thinning of pipe-wall caused by type Ⅱ hot corrosion.
通过化学成分分析、金相分析、宏观和微观腐蚀形貌观察、腐蚀产物分析以及相关的理论计算后认为,SA-178A低碳钢余热锅炉换热器管道爆裂的主要原因是硫酸盐低温热腐蚀引起的管壁外部严重减薄导致的,蠕变以及管内压力的综合作用加速了管道爆裂过程。
