黑体

The emission from a blackbody is usually considered as the maximum that an object can radiate.

排放从黑体通常是被视为最大的一个对象可以辐射。

On condition that, the radiant emittance value of detector surface was researched , in a certain distance to blackbody.

在此基础上对与黑体有一定距离的探测器表面辐射度值进行了研究。

The hot reference is usually a blackbody under environmental temperature,and the cold reference is Cosmic Background Radiation.

其中高温定标源采用处在环境温度下的黑体，低温定标源为冷空背景辐射。

Blackbody conditions can be closely realized by a small opening in the walls of a closed container.

在一个封闭容器的壁上开一个小孔，可极接近地达到黑体条件。

Using the method, the thermometer can be calibrated directly against the target source instead of a blackbody.

应用此方法，检定温度计是直接对准被测对象而不是黑体。

The result indicates that PPDW radiation is not blackbody radiation when channel pressure is 10^6Pa.

计算结果表明，当通道压力为10^6Pa时，通道辐射在所计算的温度范围内不能看作黑体辐射。

BB3200K hightemperature blackbody and its measurement system are briefly introduced.

介绍了使用的BB3200K型高温黑体及其测量装置。

Double blackbody unit for measuring parameters of infrared cameras .

红外热像仪参数的双黑体测量装置。

The model of blackbody of the first kind strictly requires the cavity isothermalness, while the model of the second kind does not.

而第二类黑体不要求等温的密闭腔体，实际上，它是一个非等温的密闭腔体。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
