(1) The calcium, phosphorus, iron & ascorbic acid contents of 73 kinds of vegetables in Nanch'ang have been determined.(2) The ascorbic acid content of one kind of turnip tops was found to be 187.3 mg/100g and that of small cabbage 106.6mg/100g. The calcium content of the lafter was found to be 185 mg/100g. All these results indicate that such contents of the Nanch'ang vegetables are higher than those of the corresponding vegetables in North China.(3) Pickling causes a decrease of both the calcium and phosphorus contents in vegetables. In salt water at room temperature, the decrease of the calcium and phosphorus contents was found to be 38.8% and 18.1% respectively, while in hot salt water the decrease was raised respectively to 45.4% and 37.9%.

(一) 本试验测定了南昌市73种蔬菜之钙、磷、铁及抗坏血酸的含量。 (二) 白萝卜缨(嫩)的抗坏血酸为百克含量187.3毫克;小白菜的抗坏血酸为百克含量106.6毫克,钙含量为百克185毫克,都远超出北方产品之含量。 (三) 泡菜的钙、磷含量都比鲜菜者减少;用冷盐水浸泡者钙减少39%,磷减少18%;用热盐水浇泡者钙减少45%,磷减少38%,说明了蔬菜在温度较高之盐水中,渗入盐水中之钙、磷量较多。

当用水淋洗碱土时,其水浸提液中的钙量恆少于普通土壤中者。水土比例增大时,淋洗出的钙量增多,惟增加量不很大。水土比例增大时,普通土壤各次滤液的pH 值并不增大,且易于达到蒸馏水的pH 值,反之,碱土的pH 值很慢的降低至pH 7.5。浸提液中CO_3~=量逐渐减少,和pH 值的降低相一致,重碳酸盐量开始时逐渐增多,以后又降低。反覆用水淋洗时pH 值亦逐渐降低。

A new method,based on the carbothermic reduction of lime,has been devised forthe direct determination of the activity of lime in liquid blast-furnace-type slags.Thesuccess of the method depends upon the proper choice of the solvent metal to lower thechemical potential of calcium in the melt.Owing to the expected very small activity co-efficient of calcium in dilute solutions in tin,the reactionCaO(in slags)+C=Ca(in tin)+CO.has been studied with a view to evaluating activities of lime in liquid CaO-SiO_2 andCaO-Al_2O_3-SiO_2...

A new method,based on the carbothermic reduction of lime,has been devised forthe direct determination of the activity of lime in liquid blast-furnace-type slags.Thesuccess of the method depends upon the proper choice of the solvent metal to lower thechemical potential of calcium in the melt.Owing to the expected very small activity co-efficient of calcium in dilute solutions in tin,the reactionCaO(in slags)+C=Ca(in tin)+CO.has been studied with a view to evaluating activities of lime in liquid CaO-SiO_2 andCaO-Al_2O_3-SiO_2 slags.The activity values in the CaO-SiO_2 system have been used toderive silica activities through the Gibbs-Duhem relationship.The shape of the activitycurves is briefly discussed on the basis of a statistical mechanical model.It has been found from the results on the ternary system that the activity of lime isincreased by the presence of 10% alumina in the slags for the entire basicity range underinvestigation.An explanation based on the ionic constitution of slags is offered for thisbehaviour of alumina.

利用石灰的加碳还原反应,设计了一个新的研究方法,以直接测定液态高炉型渣中CaO的活度.这一方法的成功,依靠溶剂金属的正确选择以降低熔液中钙的化学位,而使金属钙量提高到可以用化学分析测定的水平.我们估计钙在锡稀溶液中的活度系数很小,可能符合于我们的要求,因此研究了下列反应:CaO+C(石墨)=Ca(锡)+CO(气).以测定液态CaO-SiO_2和CaO-Al_2O_3-SiO_2渣中CaO的活度,在上式中符号下波纹线表示溶于渣中的组分,直线表示溶子金属中的组分,下同.对于CaO-Si0_2系,应用Gibbs-Duhem关系从CaO活度值算出了SiO_2的活度值,并根据一个统计力学模型讨论了活度曲线的形状.从CaO-Al_2O_3-SiO_2系的研究结果,可知在所研究的整个碱度范围內,渣中存在10%Al_2O_3都使CaO的活度增加;当Al_2O_3为20%时,则对CaO活度的影响视碱度不同而异.对Al_2O_3的这种行为,根据炉渣的离子结构理论提出了解释.
