  product content
A quadruple increase of xylitol content in dry matter of a solution (from 11.5% (w/w) to 44.5% (w/w) brought about a 2.3-fold increase of the product content in the solution (15.2% (w/w) of dry matter).
      
An analytical framework where heterogeneous consumers are imperfectly informed about product content is used to investigate the welfare effects of a public labeling system.
      
The reason for absence of any significant correlation coefficient between the recovered product content and the mineral deposit thickness is revealed.
      
Additionally, product content can take on a variety of forms that take much more effort to manage than their predecessors.
      
But, unlike product content or safety labels, the claim cannot be verified by testing the product itself.

(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...

(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。

The usage of microscope projection is introduced to analysis the different kinds of animal fibres content, by the difference of fibre surface configuration to identify one from others and then count the quantity and finally, derive the content of different animal fibres. Through practical usage it is proved that this method is feasible. It can be used to determine not only the quantity of animal fibres but also that of chemical fibres.

本文介绍了利用显微镜投影法,研究不同动物纤维混纺产品纤维含量的分析方法,根据各种动物纤维表面形态特征的差别,进行测量计数,并通过定量计算,得出各种动物纤维的含量。经过验证试验,确立了方法的可行性。本方法不仅适用于各种不同动物纤维混纺产品的含量分析,也适用于各种化学纤维混纺产品的含量分析。

In HCl medium, bis (Sodium Propyl-Sulfonate) disulfide (Ⅰ) can be directly titrated by standard KBrO_3-KBr solution. The end point is indicated by the disappearance of I incision in (dE/dt)-E alternate current ocsillopolarogram or by twin-polarized platinum microelectrodes amper- ometry. The obtained results of these two methods are consistent.

在盐酸介质中,二硫化二丙磺酸钠(Ⅰ)可以被KBrO_3—KBr标准溶液直接滴定。其滴定终点可以用在I的dE/dt-E交流示波极谱图上切口的消失指示或用双极化铂电极安培法指示。用两种方法得到的测定结果是一致的。光亮镀铜添加剂二硫化二丙碳酸钠(SC_3H_6SO_3Na SC_3H_6SO_3Na)国内首先由贵州大学化工厂研制生产,产品含量用溴酸钾容量滴定法测定,滴定终点由过量的溴使溶液变黄指示。由于人眼对黄色不敏感,滴定误差较大。有机二硫化物可用电分析容量法测定。我们用交流示波极谱滴定法和双极化铂电极电流滴定法测定了这种有机二硫化物。两种方法测定结果基本一致。
