求翻译：玻璃是一种非晶态的固体材料，这种物理特征说明了它没有固定的熔点，只有一个软化的温度范围，当温度下降时，玻璃液变得越来越粘稠，直至为固体，但是其间内部结构并没有发生明显的变化。是什么意思？

Glass is an amorphous solid material, such physical characteristics that it has no fixed melting point of only a softening temperature range, when the temperature drops, the liquid glass becomes more and more viscous until it is a solid, but during which the internal structure and no obvious changes

Glass is an amorphous state of solid materials, such physical characteristics of its melting point is not fixed, there is only one of the softening temperature range, and when the temperature drops, the glass is becoming more and more viscous, until it is solid, but internal structures and there is

The glass is one kind of amorphous state solid state material, this physical characteristic showed it does not have the fixed melting point, only then a softened temperature range, when temperature drop, the vitreous humor becomes more and more sticks thickly, until is the solid, but during the inte

Glass is an amorphous solid material, melting point of such physical characteristics described it is not fixed, only a softening temperature range, when the temperature drops, glass becomes more viscous, solid, but there had been no significant changes in internal structure.
