如图1所示,由于玻璃在熔化过程中有逐渐变软的特性,民间艺人利用喷灯熔化碎块玻璃,通过拉伸、弯折、揉捏等技法制成各式各样的小型工艺品,令人喜爱.玻璃的这种特性与金属类物质有什么不同呢?晶体和非晶体的定义和特点自然界中的固体物质可以分为晶体和非晶体两大类.从微观上讲,分子整齐规则排列的固体叫晶体,如海波、冰、食盐、金刚石、萘、各种金属等.从宏观上讲,晶体的特点是有固定的熔化温度,如冰在熔化过程中,虽
As shown in Figure 1, due to the gradual softening of the glass during melting, folk artists use flashing torches to melt pieces of glass and make a wide variety of small handicrafts by stretching, bending and kneading techniques, People like this glass What is the difference between this kind of metal substances? Crystal and non-crystal definition and characteristics of the solid matter in nature can be divided into two categories of crystals and non-crystal. Microscopically speaking, the molecular neat and regular arrangement The solid is called crystal, such as Hypertherm, ice, salt, diamond, naphthalene, various metals, etc. From a macro perspective, the crystal is characterized by a fixed melting temperature, such as ice in the melting process, although
