INTRODUCTION: In esophageal achalasia, pneumatic dilations proide short-term and long-term remission rates of 60–90% and 40–50%, respectiely.

目的： 对于贲门失弛缓症患者，球囊扩张的短期和长期复发率分别为60–90%和 40–50%。

Combining the definition of CWT and the derivative property of convolution, we constructed a general method to calculate the approximate derivative of signal through CWT by using the first and second derivative of Gaussian function, Haar, and the first derivative of three-order-Spline function as wavelets. As compared with the other approaches of calculating derivative, which include the numerical differentiation, polynomial filters, Fourier transform, and the recently proposed DWT method, fast calculation and simple mathematical operation were remarkable advantages of CWT method. For the signal corrupted by severe noise (Signal-toNoise Ratio=5), the satisfactory results could also obtained via CWT method through appropriately adiusting the dilations.

在此基础上，(1)结合连续小波变换的特点和卷积的微分性质，提出了使用Gaussian函数的一阶和二阶导数，Haar和三次样条函数的一阶导数作为小波函数的连续小波变换计算信号近似导数的一般性方法，与其他导数计算方法(包括数字微分法，多项式滤波法，Fourier变换法和离散小波变换法)相比，本法简单便捷，计算速度快，对于噪声含量较高的信号(S/N为5)，只要适当调节尺度即可获得比较满意的结果。

Our data suggest that the site, age, and histological characteristics of the lesion allow us to define VT dilation as a nosological entity distinct from other cystic dilations of the conus medullaris.

我们的数据提示病灶的部位、发病年龄和组织学特点可以让我们将VT扩张作为一个病种从其它的脊髓圆锥囊状扩张疾病中鉴别出来。

Beginning 10 days after the initial internal urethrotomy, the second group had urethral dilations with Benique dilatators (maximal 21F) under intraurethral anesthesia, weekly for the first month, once after three and after six months, and then annually.

在最初接受内视镜尿道造口术后的10天内，第二组利用Benique扩张器(最大 21F)，在麻醉下进行尿道的扩张，首先第一个月是每周进行一次，在来分别在3个月后和6个月后各进行一次，然后每年进行一次。
