脑组织含水量测定目前普遍采用干燥称重法。这种办法比较费时,且影响因素较多,精确性较差。国外学者应用高纯度煤油与溴苯制备密度梯度密度法测定脑组织含水量,但
The determination of water content in brain tissue is commonly used dry weighing method. This method is time-consuming, and has many influencing factors and poor accuracy. Foreign scholars have used high-purity kerosene and bromobenzene preparation density gradient density method to determine brain tissue water content, but
