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。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
