The nucleation and crystal growth of calcium oxalate were studied under different conditions using a nephelometer to measure the turbidities of suspensions produced when dilute solutions of calcium chloride dihydrate and sodium oxalate were mixed. The amount of material produced was less when calcium was in excess of oxalate than vice versa. For equimolar amounts of the precipitating reagents the rate of formation of calcium oxalate was rapid when calcium and oxalate concentrations were 1-25 mmol/l. but slow when they were 0-5mmol/l. Sodium citrate and heparin inhibited nucleation and crystal growth and at certain concentrations prevented nucleation for the duration of the experiment. The method is simple and quick and requires only a small amount of material.
使用浊度计研究了在不同条件下草酸钙的成核和晶体生长情况，通过测量二水合氯化钙稀溶液和草酸钠稀溶液混合时产生的悬浮液的浊度来进行研究。当钙过量于草酸盐时，产生的物质数量比反之的情况要少。对于等摩尔量的沉淀试剂，当钙和草酸盐浓度为1 - 25 mmol/L时，草酸钙的形成速率很快，但当它们为0 - 5 mmol/L时则很慢。柠檬酸钠和肝素抑制成核和晶体生长，在某些浓度下在实验期间可防止成核。该方法简单快速，只需要少量材料。
