A particular feature of this crystal is that it reacts to electric currents in predictable ways by untwisting to varying degrees depending on the voltage of the current to which it is exposed. Hence the "liquid" part of the crystal's moniker: Rather than being an oxymoron How can a solid also be a liquid?

水晶的一个特别的特性是它会对电流起可预测信方式的反应藉由根据它暴露潮流的电压分开变化的程度来起反应的，因此水晶标示的液体部分，而不是一个矛盾法又是固体又是液体？

It has been proved that light scatter in KDP crystal aggravated when pyrophosphate was doped into the growth solution,which distributed ununiformly in prism and pyramidal sectors of KDP crystal.

掺杂焦磷酸的情况下降温生长了 KDP晶体，采用激光层析法对晶体的光散射现象进行了观察，掺杂后晶体的光散射现象明显加剧，晶体的锥面、柱面和椎柱交界面处的散射点密度并不相同，其原因在于焦磷酸对KDP晶体的锥面和锥面的影响不同。

The results show that the alloy undergoes obvious plastic elongation, the specimen fractures into four sections and the diameter changes from 16 mm to 12 mm. The fracture surfaces distribute randomly well developed and partially developed veinal patterns. The deformation behavior of alloy is non-Newtonian flow behavior. About 3% amorphous matrix of extruded specimen transforms crystal, the crystal particles with size of 10-20 mm are precipitated in the amorphous matrix, the thermostability of the extruded specimen was lowered. The failure of the alloy is mainly attributed to non-uniform viscous flow under high strain rate resulting from the hydrostatic extrusion process.

结果表明：非晶合金在高应变速率下产生了明显的塑性变形，直径从16 mm变为12 mm，断裂为4段，且样品断口上随机分布着充分发展与未充分发展的脉纹式切变带，由此可看出非晶合金的变形为非牛顿体变形行为；挤压后的样品约有3％的非晶相发生晶化，在非晶基体上析出10～20 nm的纳米晶粒，导致挤压后非晶合金的热稳定性降低；静液挤压高应变速率变形条件使非晶合金产生非均匀流变，是造成非晶合金断裂的主要原因。
