Thus it is doubted as the snow unmelted through winter.
人们怀疑那是未融的积雪停驻在冬天。
Unmelted gels have the same melting point as the surrounding resin, but remained colder than the average melt temperature.
不熔凝胶与周围树脂有同样的熔点,但是受热温度比平均温度低。
The results show that the partial unmelted region, casting defect structure and secondary crack form in the welding seam, which result in the low stress breakage of the samples.
