1) postural injury
体位性损伤
1.
Objective To investigate the measures for preventing the postural injury induced by high intensity focused ultrasound (HIFU) in the treatment of patients with tumor.

2) elastic damage body
弹性损伤体
1.
Firstly,based on the statistical character of strength,rock micro-unit was abstracted into the parallel connection of elastic damage body and viscous body,and then a new statistical damage constitutive model of rock under dynamical load is deduced according to the working character of rock under dynamical load.
抓住岩石微元强度具有统计规律的特点,将岩石微元体抽象为弹性损伤体与各向同性粘性体的并联体,根据岩石在动态荷载作用下的受力特点,建立了岩石动态统计损伤本构模型。
3) viscoelastic solids with damage
损伤粘弹性固体
4) viscoelastic solids with damage
损伤黏弹性固体
5) cemented soil damage
土体结构性损伤
6) elastic solid with damage

补充资料：体位性低血压
体位性低血压
postural hypotension
又称“立位性低血压”、“直立性虚脱”。在立位时血压显著下降，可伴有脑缺血症状，取平卧位后，血压回升，症状消失。病因不明，可能与体位改变时，纠正血流动力变化的神经反射调节功能失调有关。可发生于多种疾病如脊髓痨、交感神经截除术后、长期卧床的患者及少数无明显疾病者。此外，也可发生于服用降压药物患者。诊断根据临床表现，当患者从卧位转为立位后，每分钟测血压1次，共5次。如收缩压下降6.67kPa左右，即说明有立位性血压降低。治疗可穿弹性长筒袜或弹性紧身长裤，肾上腺皮质激素或麻黄素、中药有辅助治疗作用。
