扭转的

Objective: To evaluate the diagnosis and treatment of testicular torsion and spermatic cord torsion, and to improve its diagnosis and treatment.

Inelastic torsional response due to strength distribution was studied according to the results of three-dimensional nonlinear time-history analysis.

通过弹塑性时程分析，得到了强度分布控制弹塑性扭转的作用机理，得到了质量偏心体系和刚度偏心体系强度分布影响弹塑性扭转反应的规律。

Based on variation principle, a free vibration variation-integration equation of cantilever curved pipe for conveying fluid is derived. This is a bending-torsion-fluid tree phase coupled dynamics problem. It is difficult to uncouple and to obtain bending and torsion analytic solution separately. We can only look for approximate solution or numeral results.

根据变分原理导出了悬臂输液曲管的变分－积分方程，这是弯曲－扭转－流体三相藕合的动力学问题，无法解藕而单独求出弯曲和扭转的解析解，只能作近似计算。

The "whirl sign" and the "beak sign" are the characteristic images of intestinal volvulus on MDCT.

MDCT对肠扭转的诊断和评估扭转肠管的血运情况具有重要价值。

Objective To investigate the pathogenic reasons,early diagnosis and treatment methods of intes-tine and sigmoid colon volvulus in adults.Methods 18cases of volvulus were reviewed and analyzed reading the books about this.

目的 探讨成人小肠及乙状结肠扭转的发病原因、早期诊断及治疗方法方法回顾分析了我院近年来收治的18例肠扭转病例，复习近年来的相关文献。

Volvulus is most common in adults, where it occurs with equal frequency in small intestine and colon (in either sigmoid or cecum which are more mobile).

大多数成人发生盲肠扭转较为多见，与小肠和一种结肠发生扭转的几率是相等的。

The spot is on reflection, multiturn potentionmeter turn to black, and note the rotation of the presetable until the status light.

不兵平不面侧差底色，众圈电位器向暗不本的目的回旋扭转，并记下回旋扭转的格数，直到状况指示灯平不躺下。

Objective To improve the diagnosis and treatment of testicular torsion.

目的总结睾丸扭转的早期诊断及治疗方法，提高睾丸扭转的诊治水平。

objective:to improve the diagnosis and treatment of testicular torsion.methods:the date of 13 cases of testieular torsion 2003.8～2008.5 in our hospital were retrospectively analyzed.results:all of the 13 cases were assessed correctly by cdfi,among them,excision 6,1 undescended testis,under-took orehiopexy.

目的：提高睾丸扭转的诊治水平。方法：对我院2003年8月～2008年5月收治的13例睾丸扭转的诊断及治疗作回顾性分析。结果：13例均行cdfi确诊，其中手术切除9例，3例为隐睾扭转，因睾丸生机恢复而行睾丸固定术。

There are two causes leading fractures of the endodontic instruments. Firstly as the value of the toque inc1ases beyond the limited toque, the instrument will twist with no increase in toque and will fracture soon. The value of limited toque is proportional to 3 squares of the file radius.

根管器械断裂的原因主要有2个：一是扭转超过极限扭距，器械顺着扭转的方向发生塑性扭转直至断裂，圆杆的极限扭距与其半径的3次方成正比；二是器械在循环载荷下发生疲劳损伤，最后突然断裂。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
