pH scale的意思是pH标度。定义：pH标度是一个用于量化溶液酸碱性的数值标度，其数值范围通常在0到14之间。应用：在化学、生物学、环境科学等领域，pH标度被广泛应用于测量和描述溶液的酸碱性。例如，在生物学中，不同的生物体对溶液pH值有不同的适应性；在环境科学中，溶液的pH值会影响污染物的存在...
pH scale- (from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is...
Lemon juice is an acid with a pH of 2, while baking soda is an alkali with a pH of about 9.5.(檸檬汁是 pH 值 2 的酸,小蘇打則是 pH 值大約 9.5 的鹼。) 那標示 pH 值的量表就稱為pH scale,簡單幫大家複習一下,pH 值 7 是中性,小於 7 就是酸性,大於 7 就是鹼性喔!可以參考下面這...
Chemistry Tutorial 11.3: pH (The Basics) This video shows the basics of pH without the hard-core math, and how pH values relate to each other. pH Scale Simplifying the pH scale. It explains a logarithmic scale and the inverse nature of the pH scale. A great starting point for discussing...
PH值的英文全称：potential of hydrogen potential of hydrogen的中文意思：酸碱度 pH，亦称pH值、氢离子浓度指数、酸碱值、[离𢀖]（音ㄌㄧㄥˊ）标值，是溶液中氢离子活度的一种标度，也就是通常意义上溶液酸碱程度的衡量标准。这个概念是1909年由丹麦生物化学家瑟伦·索伦森提出的。“pH”中...

The pH value is an essential factor in chemistry, medicine, and daily life. Read the text below to find out what is the pH scale and the pH formula. In the end, we will also explain how to calculate pH with an easy step-by-step solution. Our calculator may ask you for the ...
The pH scale is a measure of acidity/alkalinity and provides information about how substances tend to act in aqueous solutions. All living processes occur in an ideal pH range. Buffers act together to keep the pH within a certain range, based off the release or absorption of hydrogen ions.Ch...
目前我们最主要的目标还是想为 SeaTunnel 做一个开源可视化的数据开发和管理系统,后面期望 Scaleph 能够最大程度的降低实时和离线数据任务的开发门槛,为开发人员提供一站式的数据开发平台。 项目亮点 在真正的生产应用中,进行数据集成的时候,以可视化任务编排或 SQL 开发为数据集成的主要形式,我们认为 Drag and Drop ...
