Objective To practice a three dimensional measurement of the width of subacromial space during passive and active arm abduction in healthy volunteers and patients with impingement syndrome, and to analyze potential functional deficits of the supraspinous muscle in patients with impingement syndrome.

目的 对健康人及肩峰撞击症患者的上臂主动和被动外展过程中的肩峰下空间宽度进行三维测定，分析肩峰撞击症患者潜在的冈上肌功能缺陷。

Methods The findings at conventional MR imaging,MR arthrography examination were retrospectively reviewed in patients with arthroscopic evidence of internal impingement and subacromial impingement.

回顾性分析经关节镜证实的10例肩关节内在撞击综合征和10例肩关节肩峰下撞击综合征的常规MR成像、MR关节造影检查资料。

Among all of the cooling technologies, the impingement cooling is the most potential one to enhance local heat transfer coefficient. The impingement of the jet forms high speed airflows on the cooled surface. These airflows can be used to improve local heat-transfer conditions significantly especially in the area with very high heat flux and temperature.

在所有提高传热的技术中，冲击冷却对于提高当地的传热系数具有最大的潜力，其冲击所形成的高速气流，极大的改善了当地的换热状况，特别适用于局部高温的地区。

Then, the method to estimate cavitation erosion characteristic of high pressure piston plunger pump by analyzing impingement angle on outlet of throttling groove is put forward. That is, to hold the impingement angle range of 30°～60°as appraisal criterion of cavitation erosion characteristic on high pressure hydraulic plunger pump.4 The throttling characteristic of hydraulic control valve is studied by CFD calculation and experiment.

最后，提出了一个通过分析节流槽出口处的射流方向来评价高压轴向柱塞空蚀特性的空蚀评价方法，即将节流槽出口的射流角范围30°～60°作为评价高压轴向柱塞泵空蚀特性的标准。4对液压控制阀的节流特性进行了CFD数值计算和试验研究。

From October 2006 to March 2007, 31 shoulders (13 men and 18 women with average age of 54.3) with subacromial impingement syndrome, from our department, were selected to form the patient group, An age and gender-matched of 40 asymptomatic shoulders (18 men and 22 women with average age of 52.8) formed the control group. The acromion index was measured on the Grashey view. The distance from the glenoid plane to the lateral border of the acromion was divided by the distance from the glenoid plane to the lateral aspect of the humeral head to calculate the acromion index.

方法］对本科2006年10月~2007年3月就诊的肩峰下撞击综合征患者31肩（平均年龄54.3岁，男13肩，女18肩）的G rashey位片，计算肩峰指数即肩峰最外侧缘至肩关节盂平面的距离与肱骨近端最外侧缘至肩关节盂平面的距离的比值，通过肩峰指数对肩峰肱骨头相对位置进行定量评估，与正常人群40肩（平均年龄52.8岁；男18肩，女22肩进行比较、分析。

The larger the acromion index, the higher the ascending force component during active abduction and the higher of the pressure in the subacromial space. The situation may cause the subacromial impingement syndrome.

在较大的肩峰指数所反映的肩峰肱骨头位置关系中，外展时三角肌对肱骨头向上的分力大，肩峰下间隙内压力高，易引发肩峰下撞击综合征。

I had a lovely dog named PiPi, he was one of my best friends.

我曾经有过一只小狗，它的名字叫皮皮，它很善良，它是我最忠实的朋友。

Newly ovulated mouse oocytes were cultured in the CZB medium supplemented with different concentrations of pyruvate before treated for activation or assayed for MPF activity.

我们猜测卵母细胞在不含丙酮酸的条件下老化的更快，并且卵丘细胞可能通过消耗不含葡萄糖的CZB中的丙酮酸从而促进卵母细胞老化。
