Based on the ability of neural network in classification and recognization, a feed-forward multi-layer neural network is applied in the diagnosis of adhesive bond quality between metallic and nonmetallic components of a pressure vessel through acoustic feature extraction in the frequency domain, based upon the acoustic response on knocking the pressure vessel.

本文基于神经网络对目标的识别与分类能力，用简单的敲击法获取了某压力容器的声响应信号，通过对声信号的频域特征提取，应用前馈多层神经网络对压力容器的金属与非金属部件之间的粘接质量进行了诊断。

Methods Retrospective analysis of 120 cases with multi-slice abdominal CT scanning were randomly and equally divided into experimental group and control groups, which group was 60 cases, respectively using automatic tube current modulation techniques and constant tube current in abdominal CT examination, the statistics were weighted CT dose index, dose-length product and effective milliampere seconds to compare image noise characteristics and the details show results.

回顾性分析我院腹部多层螺旋CT检查120例，随机分为实验组与对照组各60例，分别采用自动管电流调制技术和固定管电流技术进行腹部CT检查，分别统计CT剂量权重指数、剂量长度乘积及有效管电量，并对图像噪声特性、细节显示结果进行比较。

The relationship between the hardness and the modulated wavelength was studied.

研究了多层膜硬度与调制波长之间的关系。
