一、酸硷平衡的含义:调节体液的PH值,使其限制在一个狭窄的范围(PH=7.35～7.45)之内变动,称之为酸硷平衡。人体体液的酸硷与化学上的酸硷含义有所不同。(一)化学上的酸硷:凡溶液中能放出H~+的物质叫做酸,凡能接受H~+的物质叫做硷。例如:H_2CO_3(?)H~++HCO_3-酸NH_4~+(?)H~+NH_3 硷H_2PO_4~-(?)H~+HPO_4~-又如HCO_3~-既可以是酸HCO_3~-→H~++CO_3~=,而又可以是硷HCO_3~-+H~+→H_2CO_3(二)生理上的酸硷:
First, the meaning of acid-base balance: Adjust the body fluid PH value, so that it is limited to a narrow range (PH = 7.35 ~ 7.45) within the change, called the acid-base balance. Human body fluid pH and chemical pH different meaning. (A) chemical pH: Where the solution can release H ~ + material called acid, who can accept H ~ + material is called alkaline. For example: H_2CO_3 (?) H ~ + + HCO_3-acid NH_4 ~ + (H) + NH_3 Alkali H_2PO_4 ~ - ~ H ~ + HPO_4 ~ - Another example is the HCO_3 ~ - either acid HCO_3 ~ - → H ~ ++ CO_3 ~ =, but can be the base HCO_3 ~ - + H ~ + → H_2CO_3 (B) Physiological pH:
