光度

According to the technologies it takes, the enzyme activity detecting approaches could be divided into spectrophotometric and radiochemical assays.

根据使用的手段可分为放射性同位素标记法和分光光度法。

And the unit of the exposure is lx s in photometry, while μJ/cm^2 in radiometry.

曝光量在光度学里的单位是μJ/平方公分s，在辐射度学里的单位是μJ/平方公分。

The model of the received power is established based on the basic principles of geometry optics and radiometry. This model provides the principle of receiver-transmitter design and performance evaluation. On the basis of the received power model and APD noise model, the response of measurement signal after passed through the frequency difference circuit and the corresponding change of its SNR are studied.

研究了非合作目标测距时，发射视场与接收视场的重叠情况，以及视场重叠区域内光的探测情况，并以此为基础，根据几何光学和光度学的基本理论，建立了非合作目标测距中接收光功率的数学模型，为接收/发射器的结构设计，以及测距性能的预测提供了理论依据。

In this paper, based on the comparison between CMOS and CCD image sensor and according to the principles of photometry and radiometry, the imaging range formula of CMOS image sensor in space-based system for space targets is derived with detail analysis, considering the metric of Signal-to-Noise Ratio and taking deep space as background.

在对CMOS和CCD传感器进行对比的基础上，从信噪比的角度出发，以深空作为背景，根据光度学和辐射度学的基本原理，对基于CMOS图像传感器的天基空间目标监测系统的成像距离进行了详细分析和公式推导，并以STAR-1000 CMOS图像传感器为例验证了理论模型和计算公式的正确性，最后对进一步提高CMOS图像传感器成像距离的方法进行了简要分析。

On the basis of this the photometric side of the problems of space reddening etc....

我們提出了在兩色光度学中物端光栅所能接觸到的问题，着重地敘述了空间吸收和光度型的辨認，並且把应用这种方法的先決條件，它的優點和它所受到的限制加以讨论。

The experimental procedure were predigested under the condition that did not effect the experimental results by using alkal potassium persulphate oxidation -ultraviolet spectrophotometry to determine the total nitrogen in water sample with first water instead of redistillation non-ammonia water.

经实验证明，用碱性过硫酸钾氧化-紫外分光光度法测定水样中的总N，以一次蒸馏水代替重蒸馏无氨水，既减少了实验操作程序，又不影响测定结果，同时本文确定了最佳实验条件，并对标准样品进行分析，结果理想。

In the experiment,glass chest was used to simulate indoor roomage environment.The formaldehyde concentration in the simulative room was measured by the method of acetyl acetone with spectrophotometer.

实验以玻璃箱模拟室内空间环境，应用乙酰丙酮分光光度法和邻苯三酚自氧化法测定在不同甲醛含量下芦荟对甲醛的吸收及其体内过氧化物酶活性的变化情况。

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。
