变窄

The addition of iso-octane extends the knocking limit in equivalence ratio somewhat, however the knock occurrence mainly depends on the total concentration of mixture. Although the operation range in equivalence ratio becomes narrow with the increasing of iso-octane, the maximum load is improved 80% by n-heptane/iso-octane controlled real-time in contrast with the HCCI fueled with n-heptane only.

结果表明：混合燃料HCCI着火以及燃烧相位主要取决于正庚烷实际的燃空当量比；异辛烷的加入对爆震当量比界限有所拓展，但HCCI爆震主要与混合燃料总当量比有关；随着辛烷值比例的提高，导致HCCI运行范围变窄，但是实时调控证明相对纯正庚烷，混合燃料的HCCI燃烧最大负荷提高了80%。

The welding deformation and residual stress are decreased evidently.The dimensional stability and service security of the welding structure are increased obviously.The impact absorbing energy of weld is improved by 21% under vibratory weld conditioning. And the effect of mechanical vibration on the impact absorbing energy of weld is greater than that of HAZHAZ are refined distinctly. The fusion area and overheated zone are narrowed. And the dimension of Widmanstaten structure minishes or disappeares.

试验结果表明：振动焊接后，焊接变形和残余应力明显降低，焊接结构尺寸稳定性和使用安全性大大提高，振动焊接后焊缝试样的冲击吸收功平均值比常规焊接下冲击吸收功的平均值提高了21%，且振动焊接对焊缝冲击性能的影响要明显大于对热影响区冲击性能的影响；振动焊接使得焊缝和热影响区的组织明显细化，熔合区和过热区变窄，魏氏组织减小或消失。
