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.

结果表明：在焊缝区域内存在着局部未熔区以及铸造疏松组织和二次裂纹等缺陷，这是导致试样低应力断裂的根本原因。

Aiming at the unmelted powders splash from collision between electron and powders, optimized process parameters is selected to pre-heat the powders to obviously reduce the splash.

针对实验中出现的电子与粉末碰撞造成的未熔粉末的飞溅，采用优化的工艺参数对粉层进行预热，从而大大减少了未熔粉末的飞溅。

In the melting process, the shape of the unmelted ice showed obvious difference, the top of the ice in the high voltage electric field was concave and this ice was electricized with negative charges.

在融化过程中，冰的形状出现明显的差异：施加电场后冰块的上表面出现下凹，并且冰块贮存了负电荷。
