背景情况:
- 许多牙膏含有天然成分,并提供抗敏感性,从而获得市场份额.
- 牙膏中的高磨砂剂含量可能会损害牙.
- 评估牙膏的磨损性对于牙健康至关重要.
研究的目的:
- 为了评估和比较三种商用牙膏的体外磨损性.
- 为了确定这些牙膏对声音和非矿物质化人体牙的作用.
主要方法:

- 牙被分为三个组 (Colgate,Glister,Dant Kanti) 并接受了脱矿化过程.
- 自动刷牙进行了28天,在实验前和后使用形仪测量表面粗度 (Ra).
主要成果:
- 在所有三组 (p=0.005) 的非矿物化牙中,观察到磨损的统计显著增加.
- 科尔盖特和丹特·坎蒂在去矿化牙上的磨损有显著差异 (分别为p=0.018和p=0.027).
- 晶状体在去矿化牙和健康牙上的磨损没有显著差异,任何牙膏在健康牙上也没有显著差异.
结论:

01:23Abrasion Resistance of Concrete
164
Abrasion resistance is an essential characteristic of concrete that determines its durability and longevity under various wear conditions. Concrete surfaces are vulnerable to different types of abrasion. For instance, surfaces may wear down due to the constant movement of vehicles or be eroded by solids carried in water, as seen in concrete canal linings. Specific tests are conducted to measure the abrasion resistance of concrete.

01:22Toughness and Hardness of Aggregate
294
Toughness and hardness are critical properties of aggregate materials used in concrete, particularly on pavement surfaces and industrial flooring subjected to heavy loads. Toughness is defined as the aggregate's resistance to failure by impact and is measured by the aggregate impact value (AIV). For this, the aggregate impact value test is performed, wherein the impact is delivered by a standard hammer, which falls freely under its own weight onto the aggregates. The aggregates fragment in...
