对产于烟台金斗山金矿内的贯通性非金属矿物石英及碳酸盐类的化学成分、晶体习性、流体包裹体和天然热发光特征做了研究，结果表明，矿床的主成矿阶段的环境介质为酸性偏中性，富矿和贫矿石英的热发光曲线均为双峰型，但峰点温度、总积分强度有显著差异。

The LiF thermoluminescent detector arrays were used to measure the spatial distribution in 4π space of ejected hot electron and hard x-ray emission from ultrashort laser-solid target interaction for the first time.

首次使用LiF：热释光探测器阵列进行了超短脉冲激光与固体靶相互作用中发射的超热电子和硬X射线的全空间（4π立体角）分布测量。

Overall, 1212 MU were required for each field. Beam flatness was within ±5% and ±10% in the vertical and horizontal dimensions, respectively. Thermoluminescent dosimeters were used to evaluate dose homogeneity at 45 sites.

每一成对照野的射束各与水准轴成上或下20度之夹角，倍率系数经测量为2.68，肿瘤剂量定於皮肤表面下5毫米处（位於90%等剂量曲线），总计每单一照野的照射必须1212 MU。

As compared to thermoluminescent dosimeter, Dose Ace radiophotoluminescent glass dosimeter had more advantages in clinical dose measurement, such as repeatability, suitability, stability, and small effective area. We postulate that radiophotoluminescent glass dosimeter is one of the most useful radiation dose measurement tools in the future.

Dose Ace系统玻璃剂量计与热发光剂量计相较之下，玻璃剂量计具有好的计读值再现性、稳定性、小的有效测读区域、且可重复测读；因此可预见玻璃剂量计在辐射剂量测量方面将占有极重要的地位。

Meanwhile the defects are also studied by means of the methods of EPR, PSL, thermostimulated luminescence and absorption spectroscopy. These results indicate that the principal defects are F centers and O〓 in PSL. O〓 centers are formed by O〓 ions substituting for F ions with a trapped hole The trap depth of two kinds of F centers is obtained by using thermoluminescent spectra.

同时还利用电子顺磁共振谱，光激励发光，热释发光和吸收光谱的方法，研究了其材料中缺陷的性质，实验结果表明在光激励发光过程中主要的缺陷是F心和O〓心，其中，O〓心是O〓离子替代F〓离子并束缚一个空穴而形成的局域中心。

Mineralogic characteristics of quartz of this gold deposit, such as REE, fluid inclusion, chemical composition, unit cell parameter, infrared absorption spectrum and thermoluminescent effect, were studied systematically in this article,and some valuable information of genetic and prospecting criteria are concluded.

本文较系统地研究了该金矿床石英的稀土元素、包裹体测温、化学成分、晶胞参数、红外吸收光谱及热发光效应等矿物学特征，总结出了有重要参考价值的成因信息和找矿标志。认为康古尔金矿床主要系中深成中低温热液成因，成矿物质具深源性，直接来自围岩火山岩。

Therefore the X-ray energy spectra were measured by the absorption method, the specific X-ray approach and the NaI scintillation counter, while X-ray intensity was estimated by using 7Li thermoluminescent foils.

因此用吸收法、特征X射线法和NaI闪烁计数器测量了X射线能量，用7Li热释光片估测了X射线强度。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
