Estimate approaches of η uv 、 puv and UV directional wave spectra and their comparison

现场ηUV、PUV和UV波浪方向谱估计方法及比较

Objective To evaluate the deterioration of upper and lower urinary tract function in patients with posterior urethral valves ( PUV ) .

目的探讨后尿道瓣膜对上、下尿路的损害及治疗。

Objective : To investigate the clinical significance of paraumbilical vein ( PUV ) patefaction extent of portal hypertension .

目的：探讨门静脉高压脐旁静脉开放程度的临床意义。

Directional wave spectra can be estimated by surveying the water pressure and two dimensional water velocity at the sea bottom , which is called PUV approach .

通过现场观测水底压力和矢量流速，可以估计海面波浪方向谱，此方法称为PUV法。

Results ① In proliferative phase of PUV and POV , the display rates were 90.0 % and 83.3 % , respectively . In secretory phase , both were 100 % .

结果①增生期宫旁静脉（PUV）、卵巢周围静脉（POV）显示率分别为90.0%，83.3%，分泌期均为100%。
