weight mean diameter

Methods Thirty-two CAPD patients were selected, and their salt and water ingestion were restricted for 1-3 months. The weight, mean arterial pressure, peritoneal ultrafiltration and the inferior vena cava diameter ( IVCD) of these patients were followed up.

方法选择山东中医药大学第二附属医院肾内科CAPD治疗患者32例，限制水盐摄入1-3个月，测定限制水盐前后体重、平均动脉压、超滤量、下腔静脉直径（IVCD）等相关指标。

Preparation of Ultrafine and Spherical Nickel Powders by Aqueous Reducing Method Of the obtained power, the tap density is up to 3.0g/cm3 and weight-mean diameter about 1 mm.

反应温度为80℃。新工艺可制备振实密度高达3.0以上、质量中位径约为1mm的高质量球形镍粉。
