Volumetric bone mineral density体积骨密度
1.ObjectiveTo probe into the relationship of areal bone mineral density (aBMD) and volumetric bone mineral density (vBMD) with bone area (BA) and their effects on diagnosis of osteoporosis(OP) at various skeletal regions in Chinese women.目的探讨不同骨骼部位的面积骨密度(aBMD)和体积骨密度(vBMD)与骨面积(BA)的关系及其对诊断骨质疏松(OP)的影响。
3)trabecula bone volume骨小梁体积
4)aggregate volume fractal dimension骨料体积分形
5)skeleton and volume preservation骨架和体积保持
6)volume of coarse aggregate粗骨料体积含量
1.Effects of factors such as water to binder ratio (W/B),volume of coarse aggregate (Va) and consistency of mortar (Vs/Vm) on carbonation of medium strength level self-compacting concrete (SCC) were investigated by rapid carbonation test.采用快速碳化试验方法,研究了水胶比、粗骨料体积含量以及砂浆稠度等因素对中等强度自密实混凝土碳化性能的影响,分析了自密实混凝土碳化深度与其抗压强度之间的关系,并对自密实混凝土碳化寿命进行了理论预测。

跟骨结节骨软骨病跟骨结节骨软骨病osteochondrosis of calcaneal tubercle,Sever disease1907年Haglund首先描述此病。19Sever提出系跟骨第二骨化中心缺血性坏死。多见于7~10岁男孩。常有近期剧烈运动史。足后跟肿痛、压痛。严重者足跟不敢着地。X线摄片可见跟骨结节骨骺致密,碎裂,外形不规则。本病可自限。急性期少走路及站立,避免奔跑及跳跃,穿软底鞋,垫高鞋后跟。伴有滑囊炎者可理疗或局部注射醋酸可的松类药物。
