通过实测资料检验，计算值与实测值符合良好，表明该公式可以较好的反映游荡型河道阻力沿河宽分布的特性。

Compared with the observed data and the computed value, it is shown that the formula can represent the law of resistance transverse distribution in braided river.

这种勺型状态与年龄较轻、不伴有糖尿病、慢性血管疾病积分较低以及阻力指数低有关。

Dipping status was associated with younger recipient age, lack of diabetes, low chronic vascular score, and low resistive index.

另外，本文还分析比较了S型和U型管道的阻力变化规律，提出可用线性叠加原理计算的判据。

In addition, variations in resistance of S-like and U-like pipes are analyzed and compared. And criteria suitable for linear superposition calculation are also presented.
