查询词典 quadrant compass

The abdominal wall in the left lower quadrant, 2 finger breadths (3 cm) cephalad and 2 finger breadths medial to the anterior superior iliac spine, has been shown to be thinner and with a larger pool of fluid than the midline and is usually a good choice for needle insertion for performance of a therapeutic paracentesis.27 The right lower quadrant may be a suboptimal choice in the setting of a dilated cecum or an appendectomy scar.

在过去，常常将腹部正中线耻骨与肚脐中间定为穿刺点，现在，由于腹腔穿刺引流大量液体以及腹中部脂肪厚度增加，左下腹成为腹腔穿刺部位（表1），在左下腹部中线至髂前上棘连线上2指宽（3cm）与距髂前上棘2指宽，已经显示较中部脂肪少及腹水较多是治疗性腹腔穿刺好的首选部位27，在盲肠有扩张或阑尾切除术后瘢痕时右下腹是次选的穿刺部位，应避开腹壁下动脉，这些血管走行在耻骨与髂前上棘之间的中线然后在腹直肌中向上行走，，腹壁可见的侧支循环亦应该避开，腹腔镜检查发现侧支循环可出现在中线并且在腹腔穿刺时有导致血管破裂的风险28。

The data difference of the ipsilateral quadrant visual fields was greater than those of the correspondent quadrant visual field.

双眼同侧视野的潜伏期与振幅的数据差异大于相应视野象限的数据差异。

Based on this method, the relation curve was gained in different quadrant division and different compute methods, which between different statuses and entropy of area vector of axle centre trail in quadrant, coincidence degree and coincidence degree standard errors.

分析了在不同象限划分下，不同计算方法得到的信息熵和重合度，以及重合度标准差与状态级别之间的关系曲线。

Information entropy, coincidence degree and its standard errors of axle centre trail quadrant area vector under different bearing states are extracted, the sensibility degree of the different parameters for the bearing states in different quadrant division is analyzed. By modifying the parameter compute method, the sensibility degree is improved.
