- 儿科听力学 儿科听力学
- 耳声波排放 耳声波排放 耳声波排放
- 审计唤起了潜在的潜力
背景情况:
- 宽带 tympanometry (WBT) 提供了比传统 tympanometry 更全面的中耳功能的评估.
- 了解不同年龄段的规范宽带吸收 (WBA) 值对于儿童的准确诊断至关重要.
研究的目的:
- 研究0-12岁正常听力儿童中WBA的特征和影响因素.
- 在这个儿科群体中建立WBA的特定年龄的参考范围.
主要方法:
- 北京儿童医院对384名听力正常的儿童 (0-12岁) 进行了横截面研究.
- 进行了宽带声测量 (WBT),并使用统计软件分析了16个频率的数据.
- 使用重复测量和多变量方差分析来评估频率,年龄,耳压,性别和耳朵的影响.
主要成果:
- WBA表现出明显的与年龄相关的发育变化,在婴儿 (多峰) 和老年儿童 (单峰) 中观察到不同的模式.
- 峰值WBA频率随着年龄的增加而转向更低的频率.

3.1K
The Beer-Lambert law describes the relationship between absorbance and concentration, which combines the principles established by scientists Johann Heinrich Lambert and August Beer. Lambert's law states that when light passes through a medium, the loss in intensity is directly proportional to the original intensity and the path length of the light. Beer's law proposed that the transmittance of a solution remains constant if the product of concentration and path length is constant. The...

For AAS measurements, samples must be introduced as clear solutions, often requiring extensive preliminary treatment to dissolve materials like soils, animal tissues, and minerals. Common methods for sample preparation include treatment with hot mineral acids, wet ashing, combustion in closed containers, high-temperature ashing, or fusion with reagents.
Solutions containing organic solvents, such as low-molecular-mass alcohols, esters, or ketones, enhance absorbances by increasing...

When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar...
