动脉搏动

Sometimes with his hands before touching fontanelle, will be pulsating, but also can be seen beating, which is before the fontanelle caused by subcutaneous vascular pulsatility, if not larger subcutaneous arteries after, do not see beating, this is normal.

有时用手触摸前囟门，会感到悸动，也可看到跳动，这是前囟门皮下血管搏动引起的，如果皮下没有较大的动脉血管经过，就看不到跳动，这是正常的。

Mean velocity, pulsatility index, resistant index and the rate of stenosis of main medium-large cerebral arteries were obtained.

对52例经选择性冠状动脉造影确诊的老年冠心病患者作TCD检查，观察主要大中型脑动脉的平均血流速度、搏动指数、阻力指数和狭窄情况，并与30例健康老年人对比分析。

The waveforms of blood flow and pressure in time domain were translated into powers spectral of input impedance in frequency domain for pulsative index,resistance and charecteristic impedance of umbilical artery.

用快速傅里叶转换的方法把血压和血流波形的时域信号转换为输入阻抗的频域图谱，计算脐动脉阻力、阻抗和搏动指数。

Results The PI and RI of arteria centralis retinae in aldosteronoma patients were higher than the control group.

结果As患者视网膜中央动脉一般搏动指数、阻力指数高于对照组，且术前PI和RI增高者其术后血压往往难以恢复正常。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
