The phenomena of water dissociation for NaCl, CaCl_2, MgCl aqueous solutiondesalted by electrodialysis with single or double membranes was discussed and theconception of "pH Drift" was advanced. This paper expounded the producing condition, the direction of the ξ potentialand the effects of it on the water dissociation. If the metallic ions which can compoundwith the OH~- to form unsoluble hydroxide be Added into the solution, that the waterdissociation on cation exchange membrane will be appeared earlier and aggravated morethan the case of without these metallic ions. The degree of effect on the waterdissociation related to the values of the solubility product (K_(SP)) of those metallic ions'hydroxide.

本文讨论了对NaCl,CaCl_2,MgCl_2水溶液体系用单膜法或双膜法电渗析时的水解离,提出了pH漂移概念。阐述了电动电位的产生条件、方向及其对膜液界面水解离的影响。凡是将能与OH~-离子形成难溶性沉淀的金属离子加入溶液,均能导致阳膜在水溶液中水解离现象的提前出现并加剧。其影响程度,与所形成的氢氧化物溶度积K_(SP)之相对大小有关。

The mechanisms and forms of inorganic carbon utilization by the female gametophytes of Laminaria japonica have been investigated by pH drift technique in a closed system. The results suggest that: female gametophytes of L.japonica have weak ability of inorganic carbon utilization, which have lower pH compensation point 8.85 but higher CO2 compen-sation point 1.635 μmol/L. Various inhibitors of HCO-3uptake: acetazolamide (Az), 4′,4′ diisothiocyanatosilbene 2,2 disulfonic acid (DIDS) and 4 acetamido 4′...

The results suggest that: female gametophytes of L.japonica have weak ability of inorganic carbon utilization, which have lower pH compensation point 8.85 but higher CO2 compen-sation point 1.635 μmol/L. Various inhibitors of HCO-3uptake: acetazolamide (Az), 4′,4′ diisothiocyanatosilbene 2,2 disulfonic acid (DIDS) and 4 acetamido 4′ isothiocyano 2,2′ stibene disulfonate (SITS) have no effect on the carbon utilization by the female gametophytes of L.japonica at different concentration of 100 μmol/L, 500 μmol/L and 1.0 mmol/L respectively, which indicate only free CO2 can be utilized by the female gametophytes of L. japonica,but HCO-3.In the course of inorganic carbon acquisition, alkality of natural seawater remains stable, so pH can be used monitoring the change of inorganic carbon in a close system.

采用pH漂移技术(pH drifttechnique) ,对海带雌配子体克隆的碳素营养进行了研究。结果表明 ,海带雌配子体对无机碳的利用能力较弱 ,其pH补偿点为8.85 ,CO2 补偿点为1.635μmol/L。与HCO- 3 利用有关的抑制剂 :Acetazolamide(Az) ,4′4′ diisothiocyanatosilbene 2 ,2 disulfonicacid(DIDS) ,4 acetamido 4′ isothiocyano 2 ,2′ stibene disulfonate(SITS)均未对海带雌配子体无机碳的利用产生任何影响 ,进一步说明了海带雌配子体只以游离的CO2 为无机碳源 ,不能利用HCO- 3;同时还发现 ,海带雌配子体利用无机碳的过程中 ,并未引起碱度的变化 ,从而可以用 pH指示密闭培养过程中无机碳的变化。

Adopting the pH drift technique in Oct. 1999, different forms and mechanisms of inorganic carbon utilization have been investigated on the juvenile sporophyte of L. japonica×L. longissima in a closed system by means of various inhibitors: acetazolamide (Az), 4′,4′ diisothiocyanatosilbene 2, 2 disulfonic acid (DIDS) and 4 acetamido 4′ isothiocyano 2,2′ stibene disulfonate (SITS).

Adopting the pH drift technique in Oct. 1999, different forms and mechanisms of inorganic carbon utilization have been investigated on the juvenile sporophyte of L. japonica×L. longissima in a closed system by means of various inhibitors: acetazolamide (Az), 4′,4′ diisothiocyanatosilbene 2, 2 disulfonic acid (DIDS) and 4 acetamido 4′ isothiocyano 2,2′ stibene disulfonate (SITS). The results suggest that (1) the light saturation point of juvenile sporophyte of L. japonica×L. longisima is 200μE/(m 2·s). (2) juvenile sporophyte of L. japonica×L. longissima has a higher pH compensation point--9.79 which is not affected by the weight of material and light intensity, showing HCO - 3 is useful. Az, an inhibitor of external CA, can strongly inhibit carbon uptake of juvenile sporophyte of L. japonica×L. longissima . External CA dehydrating HCO - 3 to free CO 2 is the main pathway of inorganic carbon utilization by juvenile sporophyte of L. japonica×L. longissima , accounting for 75% of total inorganic carbon acquisition in natural seawater (pH=8.1-8.3) and 100% when the concentration of free CO 2 is close to zero (pH=9.1). (3) With regard to the effect of different concentrations of inorganic carbon on carbon acquisition by juvenile sporophyte of L. japonica×L. longissima has been studied, the rate of inorganic carbon acquisition by juvenile sporophyte of L. japonica×L. longissima would increase with an increase in the concentration of inorganic carbon from 2.0mmol/L to 3.5mmol/L, indicating that the concentration of inorganic carbon in natural seawater cannot meet the need of optimal growth of L. japonica×L. longissima .

于 1 999年 1 0月 ,采用pH漂移技术研究了海带幼孢子体的无机碳源利用途径以及无机碳对幼孢子体光合碳利用的影响。结果表明 ,在天然海水中 (pH =8 1— 8 3 ) ,海带幼孢子体外源无机碳的利用形式主要是HCO-3 ,HCO-3 由质膜外碳酸酐酶 (CA)将HCO-3 水解成CO2 ,以游离CO2 形式扩散进入细胞 ,占全部无机碳供应的 75 %。游离CO2 只占所吸收总无机碳的 2 5 % ;在游离CO2 浓度接近于零 (pH =9 1 )时 ,幼孢子体的全部无机碳源均来自于HCO-3 的水解。提高海水中无机碳的浓度能增加海带对无机碳的利用量 ,当无机碳浓度达到3 5mmol L时 ,无机碳的利用速率达到最大值 ,说明天然海水中的无机碳不能满足其最大生长的需要
