近些年来,一般把菱形晶和信封状晶归属于二水草酸钙。且发现二水草酸钙不仅可以转化为一水草酸钙,而且动物实验证实这种转变是在固-固相中发生的。本文作者用偏光显微镜的锥光系统观察草酸钙结石薄片,发现菱形晶不是二水草酸钙,而是二水草酸钙向一水草酸钙转变的过渡晶体,为进一步证实这一结论,本文用偏光显微镜旋转台法测定了典型菱形晶颗粒的光学常数。材料和方法选经治疗排出的直径约在0.5cm以下的小结石30例。经自然干燥,常规磨片。在单偏
In recent years, diamond crystals and envelope crystals have generally been assigned to calcium oxalate dihydrate. It has been found that calcium oxalate dihydrate can be converted not only into calcium oxalate monohydrate, but also animal experiments to confirm that this transition occurs in the solid-solid phase. In this paper, the authors observed the calcium oxalate stones by the cone system of polarizing microscope and found that diamond crystals are not calcium oxalate dihydrate, but transitional crystals of calcium oxalate dihydrate to calcium oxalate monohydrate. To further confirm this conclusion, The optical constants of the typical rhombohedral grains were determined by microscope rotation. Materials and Methods Selected treatment of small diameter of about 0.5cm below the discharge of 30 cases of stones. After natural drying, conventional grinding. In the one-way
