        摘要：The characteristics of ESR signals used in the dating of hamal tooth enamel fossils have been investigated. According to the comparison of the results obtained from tooth enamel with those born pure substance and the study by positron annihilation technique, it can be concluded that the paramagnetic centers of tooth enamel is Produced by PO3-4 ion formed F centers.

        摘要：Four tooth samples, collected from the 2nd, 3rd and 4th layer of a paleoanthropological site of Yinshan near Chaoxian are analyzed by ESR dating.Their ages are estimated to be 212ha, 361ha, 363ha and 456ha respectively. The age of paleoanthropological fossils from the 2nd layer is about 200ha, which is in good agreement with the results obtained by U-series dating or other methods for faunal remains as well as the paleoanthropological and paleontological evidence.

        摘要：Five samples,collected from different depth of one core drilled from Zhuoshui Fan- delta, Yunlin, Taiwan, were preliminarily tested by thermoluminescence dating. Ages of the sample younger than 50 ha are consistent with those from 14C dating method. This result indicates that the TL dating is a feasible method for the age determination of late Quaternary coastal sediments in Taiwan.

        摘要：A model is introduced for explaining the sensitivity change of the infrared stimulated luminescenceonSL) signal used for dating. The model involves the competitions of the two types of traps to captive the electrons creaked in the irradiation process, the sensitivity of the IRSL signal representS the resPOnse of the T, signal charges in the“easy to bleach”trap to the irradiation dose and depends on the concentration of election in the u hard tO bleach“ traps. It predicts that the sensitivity of the IRSL signal can be increased, decreased or unchanged aller laboratory bleaching. The sensitivity change is dependent. on the degree of sunlight bleaching prior to deposition, the age of the sample and the conditions of laboratory bleach. The predictions by the model agree well with resultS reported in the literature. Further more, the model has been tested with a specially designed experiment. The applications to optical dating with regeneration method are discussed.

        摘要：The variation of beta dose- rate with depth below the surface of a porcelain slice was investigated. The variation is due to the build- up and attenuation effectS of beta dose in the slice. It is shown that the saturation value of build-up is 1.05 at the depth of 80μ m, and therefore the average dose increment or reduction is only 2% for a thickness of 200 or 300μ m. Hence the build-up effect is negligible in the dating of porcelain slices with similar thickness.

        摘要：A linear relation between the age of α-qusrtz and its E’ centre concentration has been found when the Product at is far smaller than 1, where Q is the uranium content in equilibrium（g/g） and t is the age（Ma）. This relation can be used to determine the age of α-quartz by measuring the E’ centre concentration ther calibration with a reference sample.

        摘要：Three usual measurement methods（multiple activation technique, additive dose method and spine technique） for the pre- dose t6chnique .in thermoluminescence dating are discussed and the fine-grain quartz method has been described in detail. The results show that the fine-grain quartz method is not only sample,but also decreasing in errors of multiple activation, test dose and normalization. In addition, by using this method quite small ages（10-100year） are Possible to be accuratelyevaluated.

        摘要：The styles of pottery figures varied tremendously as time parsed by. The typical one for the Tang dynasty is the standing lady with its big he tuft, loose rote and round body to reflect the“fat”fashion at that time. Forty thee Painted pottery of staznding“lady”were studied using thermoluminescence dating techniques. The results indicate that genuine figures have similar TL characteristics, such as shape of TL glow curves, equivalent doses and TL sensitivity to irradiation dose, which are significantly different from faked ones. Even artificial irradiation cannot simulate these TL characteristics.

        摘要：An experimental study has been carried out on the ESR intensity repoonse to irradiation. The systematic error of accumulated dose AD with the simple exponential function is evaluated. It is concluded that the systematic error depends on the AD value itself. The AD values and ages of 8 enamel fossil samples collectedfrom Yunxian Palaeoanthropological Site are determined to verify the conclusion.

        摘要：Abnormal resPOnse of E’ center of quartz in coastal aeolian sand to irradiation dose has been observed. The abnormalities occur in most（>90%） of more than 100 measured samples born the coastal areas of China. It is suggested that the abnormal response of E’ center to irradistinn dose be used as an indicstot tO identify coastal aeolian sand.

        摘要：A technique of annual dose determination for unbalanced U series samples is described in this paper. The content of 238U is determined by neutron activation analysis and that of 226Ra by a Ge semiconductor detector. Escape coefficient of radon is estimated by an alpha- particle counter or a gamma spectrometer. A formula for annual dose calculation of unbalanced U series samples is derived.
