A typical (36) language contains an applicative sub-language which approximates the mathematical abstractions of "timeless" functions applied to’ "spaceless" values, where the actual operation sequences and use of storage space during expression evaluation are organized behind the (37) . In this setting, values are data structures of low volume, typically a few computer words or less, which means that an illusion of spacelessness can be realized by having (38) results during expression evaluation stored at the discretion of the language implementation, and effecting parameter (39) and (40) operations through value copying.

含有一定量CH3COONa和CH3COOH的水溶液称作“缓冲溶液”,在该溶液中加入少量的强酸或强碱时,溶液的pH几乎不变,这可由下列离子方程式来说明:

加入酸时CH3COO-+H+=CH3COOH;加入碱时CH3COOH+OH-=CH3COO-+H2O,

由于CH3COOH和CH3COO-的大量存在,溶液中的c(H+)与c(OH-)基本保持不变.

一定量的H2S和NaHS的溶液也具有缓冲作用,写出在此溶液中加入少量强酸或强碱时发生的离子反应方程式:

加入酸时______;

加入碱时______.
