Experiments on the remineralization of artificial carious enamel with radioactive isotope ~(45)Ca are presented. ~(45)Ca can be deposited in the demineralized area of artificial caries from outer environment. The experiments show that the density of the developed silver granules in autoradiograms clearly represents the intrusive quantity of calcium ion and the degree of demineralization.In addition, in this paper, the possibility of remineralization in human body; the relation between the degree of demineralization...

Experiments on the remineralization of artificial carious enamel with radioactive isotope ~(45)Ca are presented. ~(45)Ca can be deposited in the demineralized area of artificial caries from outer environment. The experiments show that the density of the developed silver granules in autoradiograms clearly represents the intrusive quantity of calcium ion and the degree of demineralization.In addition, in this paper, the possibility of remineralization in human body; the relation between the degree of demineralization and that of remineralization; and the significance in the clinical work are discussed.

取离体牙制成人龋,用~(45)Ca之同位素液体浸泡,在自显影照片上,均可见釉质层在不同钙化程度之区域显示出不同程度之黑色,如自然龋之黑色最深,人工龋和牙本质之黑度相似。表明钙化程度越低,渗入之钙亦越多。也说明了牙硬组织脱钙越严重,相应地会得到更多的钙。 牙釉质由羟磷灰石构成,脱钙后其本身结构发生改变,即在其晶格的某一位置上缺少钙离子,这些缺钙的磷灰石是不稳定的,当周围直接环境中如有一定量的钙,经过离子交换作用,钙离子能渗入牙硬组织之钙化较低部分。 经以上实验结果说明以含钙之再矿化液浸泡龋,也会得到再矿化之效果。

The high bitumen yield up to 80% of kerogen by super-critical fluid extraction of oil shale, the good agreement of H/C and infrared spectra between the kerogen, bitumen and demineralized extracted residue, suggest that the major part of kerogen is a kind of polymer. Under the experimental conditions of SCFE, since kerogen was swollen, depolymerized and extracted immediately by super-critical fluid (toluene) only with little secondary decomposition, the carbon skeleton of the bitumen remains nearly the...

The high bitumen yield up to 80% of kerogen by super-critical fluid extraction of oil shale, the good agreement of H/C and infrared spectra between the kerogen, bitumen and demineralized extracted residue, suggest that the major part of kerogen is a kind of polymer. Under the experimental conditions of SCFE, since kerogen was swollen, depolymerized and extracted immediately by super-critical fluid (toluene) only with little secondary decomposition, the carbon skeleton of the bitumen remains nearly the same as its parent .According to the 1H nmr spectrum, ultimate analyses and average molecular weight, the structural parameters of bitumen were calculated.Referring to the data, the carbon constitutional fraction of Maoming oil shale kerogen was estimated as follows. Aromatic C, 0.25-0.30; naphthenic 0,0.20-0.30 and paraffinic C, 0.40-0.45. For Fushun oil shale kerogen, the result is quite similar but a little higher in paraffinic C and lower in naphthenic. The aromatic rings are mainly cata-condensed and linked with naphthenic rings as in the te-tralin-type structures.The structural unit of kerogen may be described by the elution-chromatographical constituents, their molecular ratio and molecular weights, then the structural unit weight of the Maoming kerogen had been estimated about 4500. Its chemical formula may be written as C302H440O23N6S2.

This paper studies the method of determining trace chloride in high purity power station waters, in which lead phosphate is used as load body for coprecipirating concentrated chloride. After speed centrifugation, the precipitate is dissolved with iron (Ⅲ) nitrate perchloric acid and the mercury (Ⅱ) thiocyanate-methanol solution is added, and then spectrophotometric determination is undertaken. In this paper, the principles and analytical conditions of this method are provided. The sensitivity of this method is 0.0026 absorbance/ppb cl~-, the concentration of detection limit is 2 ppbcl~-. When chloride concentrations are 5 ppb and 10 ppb, the standard deviations of six analytical results are 0.003 and 0.002 (absorbance unit) respectively. The recoveries of determing demineralized water samples are 88-98%. The apparatus used in this method are simple and the analytical procedures are convenient. The experiments verify that this method is of practical significance for determining trace chloride in high-purity waters of power station.
