Koch perceived that it would be far better if one could solidify a well-tried liquid medium with some clear substance.

郭霍设想，如果能用某种透明物质将经过多次试验的培养液固化可能更好。

The result of the test shows: in the case of inexistence of chlorin ion, the effect of electrochemical oxidation of ammonia wastewater of the Ti/SnO_2-Sb_2O_3 electrode is better than the Ti/SnO_2-Sb_2O_3-CeO_2 electrodes,efficientry.When there exist 400mg/L chlorin ion,both have perfect effect.

对氨氮的电化学氧化去除试验表明，在不含氯离子的情况下，经过优化的Ti/SnO_2-Sb_2O_3电极的去除效果优于经过优化的Ti/SnO_2-Sb_2O_3-CeO_2电极，但效率不高；而在含有400mg/L氯离子情况下，二者对氨氮均有很好的去除效果。

By measuring the residual stresses of the cylinder of a cement ball mill in four cases,and the fatique crack spreading for the thermal treatment and the un thermal treatment test samples,the results showed that the heat treatment sample reduced the residual stress,enhanced the fatique strength and lowered the crack spreading speed.

对球磨机筒体的4种情况的焊件进行残余应力测试，并对进行热处理和未进行热处理的试件做疲劳试验及疲劳裂纹扩展测试。试验结果表明：经过热处理的试件，残余应力降低，疲劳强度提高，裂纹扩展速率降低，结构抗疲劳性能增强。不过从工程应用角度看，对于板厚为20～25mm的球磨机筒体而言，不进行焊后热处理也能保证足够的疲劳强度
