查询词典 black body radiation

His work in black body form and anisotropy of the cosmic microwave background radiation cemented our understanding of the origin of the universe.

他对宇宙微波背景辐射的黑体和各向异性的研究，巩固了我们对宇宙起源的了解。

The method amending atmosphere influence is introduced, which places large area gray body beside the target. After academic analysis and experiment research, it is found that the "black body demarcation curve" and "reference curve" intersect at the atmosphere temperature point, and the slope amending coefficient and offset amending coefficient could be calculated based this two curve. After corresponding amending on target gray, the infrared radiation characteristics could be calculated by rule and line.

介绍了通过放置在目标附近的大面源灰体修正环境影响的方法，经过理论分析及实验验证，发现"黑体标定曲线"和"参考曲线"相交于环境温度点，并且根据这两个曲线可计算出环境影响的斜率修正系数和偏置修正系数，对目标的灰度值进行相应的修正就可以准确地计算出目标的温度等红外辐射特性。

One of the most fundamental concepts for understanding heat radiation is that of a black body.

理解热辐射的最基本概念之一是黑体概念。

Based on the technique of radiate temperature measurement, the author designs a circuit of prismatic decomposition colorimetric radiate temperature measuring. A high resolution A/D converter and measurement range switch technology are adopted to resolve the problem that it has lower radiation power and lower signal sensitivity in the low-temperature stage, while higher signal amplitude and higher need of dynamic range in the high-temperature stage. The technique of the Black Body Furnace demarcates, digital calibration and the quartic curve fitting are applied to correct the sensor and improve its measurement precision.

3研究了辐射温度测量技术，设计了棱镜分光比色辐射温度测量电路，使用高分辨率A／D转换器和量程切换技术解决低温段辐射能量小、信号灵敏度低，而高温段信号幅值大，动态范围要求高的矛盾，应用黑体炉标定技术和数字校准方法以及4次拟合校正技术提高温度测量精度。

Basic quantities in stellar photographic photometry (in particular, colour index and "effective wavelength") are formulated according to the assumptions that: 1 stellar radiation may be represented by some black body equivalent and 2 within the limits of a single photometric "receiver", intensity-wavelength relationship of the radiation may be taken as linear.

本文对着当前的发展，综述了照相方法在恒星光度学中的地位。接着用两个简单的假设，即星体幅射的黑体近似和累积亮度范围中的直线近似，把恒星光度学中的基本定义(如有效波长、等光波长和色指数等)和主要问题(如空间红化，亮度效应等)表以公式。

The climate space diagram of the tomato in the solar greenhouse is quite similar to that of the cardinal studied by Gates D. M, whereas sun radiation the tomato absorbs is lower than that of the black body.

M。 Gates研究得到的北美红雀气候空间辐射极限图相类似，不同的是，番茄群体吸收的太阳辐射会低于理想的黑体所能吸收的辐射。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
