支具治疗青少年特发性脊柱侧弯的护理。
Nursing Care of Patients with Adolescent Idiopathic Scoliosis Treated with Braces.
青少年特发性脊柱侧弯支具治疗的效能存在争议，有效性仍未得到证实。
Background The efficacy of brace treatment for patients with adolescent idiopathic scoliosis remains controversial, and effectiveness remains unproven.
螺杆钻具是其中的一项关键技术，其主要目的是研制满足侧钻中短半径水平井需要的小尺寸高造斜率的弯外壳螺杆钻具。
Small size bent housing screw drill with high build rate must be developed to meet the requirements of sidetracking the short to medium radius horizontal well.
对于连续导向钻具组合来说，由于其弯螺杆的存在，使得其在任何一个瞬态的受力变形都有其独特的特征。
For a continuous steering drill tool assembly, because there is crew in it, any transient forced deformation has its special characters.
给出了带弯接头结构钻具组合的处理方法及扭矩的计算方法。
The methods to deal with bent sub and torque was also been given in this article.
弯壳体导向钻具的刚性大、变形小，因此可采用几何法来计算造斜率。
The bent-housing motor is relatively rigid, so the geometric method can be used to calculate the build angle rate of steerable motor.
辅具师是成功治疗原发性脊椎侧弯的不可或缺角色。
尽管支具治疗已经作为有曲线进展危险的侧弯患者标准的治疗方法，无论在功效和作用方面还不能经历严格的评价。
Although bracing has been regarded as the standard of care for patients at a high risk of progression, it has never been subjected to rigorous assessment of either its efficacy or effectiveness.
