This rhomboid shaped crystal of calcium pyrophosphate, which appears bluish-white ( weak positive birefringence) by polarized light with red plate. 焦磷酸钙菱形结晶在红感光板偏振光下呈蓝白色(弱正双折射)。
Radiological diagnosis of calcium pyrophosphate dihydrate crystal deposition disease 二羟焦磷酸钙晶体沉积症的影像学诊断
Calcium phosphate is changed into calcium pyrophosphate at high temperature. ( 4) In order to investigate the absorbent surface area on phosphorus and sulfur fixing effect. 为了考察吸收剂比表面积对磷和硫固定效果的影响。
