Together, UltraSnap and Hygiena’s hand held meters measure the ATP present in a sample.

ATP is the energy molecule found in all living cells and the presence of ATP signifies whether or not a surface is clean.
5
Test results are delivered in 15 seconds and are expressed in Relative Light Units or RLUs.
6
An RLU result is directly proportional to the amount of ATP collected from the sample, so the greater the amount of ATP, the greater the RLU number, and the dirtier the surface.

每天练习15到30分钟，将显著提高您的英语流利度和发音准确度。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
