梨状肌

For example, if you sit at a desk all day, your chest is probably tight and your rhomboids are probably weak. Your hamstrings and piriformis will also likely be tight and weak. As a result, postural issues and imbalances should be addressed and/or corrected.

比如，你整天坐着，你的胸腔可能会很紧张，菱形肌会很脆弱，腿腱和梨状肌也会很紧张脆弱，那么就应该校正姿势问题和不平衡感。

目的确定臀三角内梨状肌上、下孔和坐骨神经的体表定位，为临床应用提供解剖学资料。

The sacral plexus was identified at the levelof the sciatic foramen as a round hyperechoic structure.

在坐骨孔水平找到了圆形高回声结构的骶丛神经。17例病人中有10例辨别出了臀动脉，但是所有病人身上我们都没能确定地辨别出梨状肌。

Results The length between posterior superior iliac spine and greater trochanter of femur was (15.2±1.35) cm for man and (11.5±0.72) cm for woman; the length between posterior superior iliac spine and ischial tuberosity was (13.3±0.87) cm in man and (10.3±0.49) cm in woman; the length between greater trochanter of femur and ischial tuberosity was (8.3±0.83) cm in man and (5.5±0.61) cm in woman; the surface projection where the superior gluteal artery, superior gluteal veins and superior gluteal nerve permeate the suprapitiform foramen was below the point 0～6.8 mm between 2/5 superior and middle trunk from posterior superior iliac spine to greater trochanter of femur; the surface projection where the inferior gluteal artery, inferior gluteal veins and inferior gluteal nerve permeate the infrapiriform foramen was at the point between 2/5 inferior and middle trunk from posterior superior iliac spine to ischial tuberosity; the surface projection where sciatic nerve permeate the infrapiriform foramen was at the point between 3/5 lateral and middle trunk from ischial tuberosity to greater trochanter of femur.

结果臀三角各边的长度分别为：髂后上棘转子间距，男(15.2±1.35) cm，女(11.5±0.72) cm；髂后上棘结节间距，男(13.3±0.87) cm，女(10.3±0.49) cm；转子结节间距，男(8.3±0.83) cm，女(5.5±0.61) cm。臀上动脉、静脉、神经出入梨状肌上孔的体表投影在髂后上棘与大转子连线中、上2/5交界处向下0～6.8 mm内；臀下动脉、静脉、神经出入梨状肌下孔处的体表投影在髂后上棘与坐骨结节连线中、下2/5处；坐骨神经出梨状肌下孔处的体表投影在坐骨结节与大转子连线中外3/5处。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
