Polarizing microscope a light microscope that uses polarized light to illuminate the specimen . the orientation of molecules in certain crystalline substances affects the transmission of polarized light 偏振光显微镜：指利用偏振光照射样品的一种光学显微镜。在某些结晶体中，分子的方向影响偏振光的传播。
Amorphous materials have disordered atomic structure as compared to crystalline materials : that is , they have only short - range order rather than the long - range periodicity of crystals 与晶体材料相比，非结晶体材料使原子结构发生无序变化，即：它们只有晶体的短程序列特征，而没有晶体结构的长期周期性特征。
Crystalline silicon must be made 200 microns thick to absorb a sufficient amount of sunlight for efficient energy conversion , whereas only 1 micron of the proper amorphous materials is necessary 必须要使晶体硅达到200微米厚，才能吸收足够的阳光进行有效的能量转换，而合适的非结晶体材料只要1微米厚就够了。
Concerning the ph values from urinalysis , the urine containing uric acid crystals had the lowest ph value ( mean 5 . 30 ) , and the triple phosphate crystals - containing urine had the highest ph value ( mean 7 . 47 ) 至于尿液之酸碱值在含尿酸结体之尿液最低，平均为5 . 30 ；而含三重磷酸盐结晶体之尿液酸碱值最高，平均为7 . 47 。
The study showed that approximately two - fifths of the patients with urinary calculi had crystals in urine , and there was good correlation between the urinary crystals and the components of the urinary calculi 总之，将近五分之二的尿路结石病患其尿液中有结晶存在；而且其尿液中结晶体与其结石之种类具有高度之相关性。
Already , solar cells with efficiencies well above 6 percent have been developed using amorphous materials , and further research will doubtlessly find even less costly amorphous materials with higher efficiencies 用非结晶体材料研制的太阳能电池的使用功效已经远远超过6 % ，未来的研究必将找出成本更低的但功效更高的非结晶体材料。
For designing the microwave power amplifier formed by the chip of sige hbt more accurately , an novel method to extract chip s - parameter from s - parameter of packaged device with package is proposed 为了更精确设计由sige异质结晶体管( hbt )管芯构成的微波功率放大器，本论文提出了一种新颖的从管壳封装器件的s参数中提取出管芯s参数方法。
Already ， solar cells with efficiencies well above 6 percent have been developed using amorphous materials ， and further research will doubtlessly find even less costly amorphous materials with higher efficiencies 译文用非结晶体材料研制的太阳能电池的使用功效已经远远超过6 % ，未来的研究必将找出成本更低的但功效更高的非结晶体材料。
To explain this point i prepared synthetic chalcolite from pure products , and obtained crystals , whose activity was completely consistent with their uranium content ; this activity is about half that of uranium 为了解释这一现象，我准备了从纯产品中合成的铜铀云母，并得到了这种结晶体，其活性与其铀含量完全一致，活性大约是铀的活性的一半。
The course concentrates on circuits using the bipolar junction transistor , but the techniques that are studied can be equally applied to circuits using jfets , mosfets , mesfets , future exotic devices , or even vacuum tubes 本课程集中讲解使用双极结晶体管的电路，但所学技术同样适用于使用jfet ， mosfet , mesfet ，未来的稀有装置，甚至真空管的电路。
