A new methodology is proposed for investigating compressive failure behavior of cement paste at micrometer scale. Micropillar geometries are fabricated by focused ion beam milling on potential calcium...
燃料在直圆管形状的微尺度燃烧器中进行预热燃烧，对比不同预热温度下的燃烧器工作性能，检验强化预热对促进微燃烧稳定的效果。实验选择燃料混合气体流量为0.12、0.24、0.36L/min，预热温度分别为室温23℃和250、500℃。实验结果显示，在室温，燃料混合气体流量0.12L/min下，燃烧器可燃极限当量比为0.339~3.639。预热温度上升到250℃时，可燃极限当量比范围增大到0.317~...
