正常张力 meaning in English

normal tension

The earlier authors use splint to control abnormal muscle tone or prevent deformity of distal parts of the limbs , while the later authors consider that good control of total posture would release the distal muscle tone without the splints or other devices because those would increase abnormal muscle tone
早期作者都企图以副木或类似之外物来控制不正常张力对肢体末端的影响，近来之作者发现这些处置效果不彰，不如以姿势控制从近端到远端都摆在反痉挛的姿势上，自然末端之变形不会出现。
It has been well known that vascular endothelial cells ( vec ) are not only a mechanical and biological barrier of blood vessels , but also an endocrine organ , which maintain vascular normal tension and reactivities througth synthesis and release vasoactive substances such as nitric oxide ( no )
研究发现,血管内皮细胞( vascularendothelialcells , vec )能合成多种血管活性物质,是维持血管正常张力状态和血管反应性的关键因素。其中vec释放的一氧化氮( nitricoxide , no )是人们发现的机体第一种气体信使分子,具有明显的血管活性、介导了血管内皮依赖性舒张反应。
