不辐射

Heating of the sealing jaws is eliminated, so no unnecessary radiant heat is generated.

封口的暖气被淘汰，因此没有不必要的辐射产生热量。

Light and radiant heat both travel through a vacuum,orthe sun's light and heat would not reach us.

光和辐射热都能穿过真空传递，否则太阳的光和热不会到达地球上。

Light and radiant heat both travel through a vacuum, or the sun's light and heat would not reach us.

光和辐射热都能穿过真空传递，否则太阳的光和热不回到达地球上。

Light and radiant heat both travel through a vacuum,orthe sun's light and heat would not reach us.

光和辐射热都能穿过真空传递，否则太阳的光和热便不会到达地球上。

This source have the advantages of high stability, high spectral radiant flux, narrow bandpass, large area, tunable wavelength in broad spectral range, etc.

这种新型的积分球光源具有稳定性好、光谱辐通量高、光谱带宽窄、光源面积大、波长在宽波段内可调谐等优点，联合响应度直接溯源于初级辐射标准低温辐射计的标准探测器，可以有效降低定标不确定度。

They give off discrete amounts of radiant energy.

它们放出不连续的辐射能量。

It carries on the thermal comfort appraisal to the low-temperature radiant floor heating system using PMV and PPD.

并利用预测平均价和不满意率舒适度指标对低温地板辐射采暖系统进行了评价。

Because of the absorption of ozonosphere existing in higher level atmosphere,the sun-blind-region ultraviolet radiation (200～280nm) of solar spectrum could hardly reach the surface of the earth. Therefore, the communication system using this spectral coverage could hardly be disturbed.

由于地球大气上层臭氧的吸收作用，阳光中的日盲区(200～280nm)辐射几乎无法到达地球表面，因此，采用这个波段的光学通信系统几乎不会受到太阳光的干扰。

The results show that the temperature of the alloy gradually decreases from the casting mouth to the exit in the roll-shoe gap, and the isothermal line deviates from the shoe side to the roll side.

结果表明：辊靴型腔内合金的温度从入口至出口逐渐降低，合金等温线向工作辊偏移；随着浇注温度的降低，辊靴型腔内半固态区间逐渐增大；为了获得优良的半固态金属浆料，确定浇注温度为710~770 ℃；合金在辊靴型腔内层流运动时，越靠近工作辊内表面，合金的运动速度越快；随着挤压模具扩展角的增大，挤压模具出口型材宽度上中心与两侧边部合金的温度差减小；半固态合金进入模具后呈辐射状逐层向前推进填充模具扩展腔，最后再逐渐向模具出口合拢；为了改善模腔内金属流动速度的不均匀性，扩展角以45为宜。

Again, Girardfound what he believed to be an explanation, or at least aprecedent: During the Cold War, the government conducted radiationexperiments on scores of unwitting victims, essentially using themas human guinea pigs.

再次吉拉德Girard发现他所相信的一个解释，或至少是一个例子：在冷战时期，政府对很多不知情的受害者进行辐射实验，尤其是把他们作为人体实验鼠使用。

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。
