光导

Very simply put, it works in this way:through asophisticated system of electronics, television providesthecapability of converting an image (focused on aspecialphotoconductive plate within a camera) into electronicimpulses,which can be sent through a wire or cable.

简单说来，电视是以这种方式工作的，通过一个复杂的电子系统，电视能够将一幅图像(这幅图像被聚焦在一部摄像机内的一块特殊的光导底片上)转换成能经过导线或电缆发送出去的电子脉冲信号。

The photoconductive properties makes them can be used broadly in Optical Data Storage, Laser printing, xerography and photovoltaic cells.

其光导性能在光学信息贮存、激光打印、静电复印、太阳能应用等诸多领域均有应用。

It is observed that after irradiation, the detectors' peak and cutoff wavelength move towards short wavelength; the room temperature resistance and current responsivity become decreasing when irradiation dosage is larger than 10 15/cm 2; the detectivity doesn't show a monotonical change owing to the influnce of noise.

在辐照剂量大于1015/cm2时，器件的室温电阻和响应率明显下降。探测率由于噪声的影响无明显变化趋势。标签碲镉汞光导型探测器电子辐照辐照效应 HgCdTe photoconductive detectors electron irradiation radiation effects

Sound enamel surfaces were dematerialized in bacteria model in vitro. QLF was used to analyze the area of lesions, the loss of fluorescence and ΔQ on enamel surfaces after demineralization. Confocal laser scanning microscopy was used to quantify the mineral content after demineralization.

将30个牙釉质块开窗后分为3组，分别使用氟含量1 450 mg/L的氟化钠牙膏、单氟磷酸钠牙膏和无氟牙膏的处理液处理，并在体外恒化器龋病模型中进行脱矿循环，定量光导荧光技术分析病损脱矿后的面积、荧光损失和总荧光损失量，激光扫描共聚焦显微镜分析脱矿后矿物质含量变化。

Second,we investigated the temporal and spectral properties of the THz emission of a novel semi-insulating GaAs interdigitated photoconductive antenna with different excited carrier densities,in a temperature range from 4.2K to 270K.

其次，我们研究了一种全新的微结构半绝缘GaAs光导天线THz辐射的时域和频域特性，特别是其在从4K到270K的温度变化范围内的THz发射特性。

On the basis of experimental investigations,two types of laser detonators were developed.

在这些实验的基础上研制了两种激光雷管，进行了多分支光导束传输激光同步引爆多发雷管的实验，引爆时间的分散度与通常瞬发电雷管相同。

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。
