利用一具熱電總日射表（球形罩封密的溫差電堆總日射表）連同累積計數器，天文臺可以量度每小時的太陽總輻射數量。 -
As we regress back toward epochs when the universe was younger, we come to the stage when the primordial radiation originated.
當我們回顧宇宙比較年輕的時代時，我們將停步于原始輻射產生的時代。 -
The earth requires greenhouse gases, including water vapor, carbon dioxide and methane, to prevent some of the heat from the received solar radiation from escaping back into space, thus keeping the planet hospitable for protozoa, shetland ponies and lindsay lohan
地球需要水蒸氣、二氧化碳、甲烷等溫室氣體，把部份的太陽輻射熱能留在大氣層里，好適合原生動物、雪特蘭迷你馬，以及好萊塢女星琳賽蘿涵居住。 -
Receiving antennas intercept part of this radiation, change it back to the form of electrical signals, and feed it to a receiver
接收天線的裝置接收部分電磁波，將其轉換回電子信號，並供給一個接收器。 -
After measuring dark current, photocurrent and response to x pulse of gaas detector before and after 1. 7 mev electronic radiation, the response tune, fall time of trailing edge, full width of half maximum ( fwhm ), sensitivity, carrier life, mobility are researched and contrasted. the result shows that the response speed of detector, time resolution ratio and nonlinear of back edge of output signal have been improved greatly after electronic radiation. though sensitivity of the detector reduces, its measuring range can be widened
為了使探測器的性能得到進一步的提高，我們對其進行了電子輻照改性，並測量了本徵砷化鎵探測器和經過1 . 7mev電子輻照的探測器的暗電流、光電流及對x射線的脈沖響應，並對其響應時間，后沿下降時間，半高寬（ fwhm ） ，載流子壽命，靈敏度進行對比，研究，結果顯示經電子輻照后的探測器的性能得到了改善，使響應速度，分辯率進一步提高，並消除了探測器輸出信號后沿的非線性，雖靈敏度有所降低，反而使其測量范圍得以拓寬。 -
C. twin tube structure with stand from front to back, with heavy - caliber specification and imported damping oil will enhance the radiation capability
前後正立復筒式構造，採用大口徑規格，進口阻尼油，增加散熱性。 -
Because the particles are so light, they remain aloft for long periods, where they cool the earth by reflecting radiation from the sun back out to space
因為這些微粒實在太輕了，他們能在高空中長時間停留，並在那裡將太陽射來的紫外線反射回太空，讓地球冷卻。 -
Sulphate particles scatter solar radiation back to space and so reduce the amount of solar radiation reaching the surface of the earth
硫酸化合物微粒將部分太陽輻射散射回太空中，這就導致了到達地面的太陽輻射總量的減少。 -
In respect of direct radiation in air and from the ground, real - time measurements are undertaken by 10 fixed stations of the radiation monitoring network ( figure 1 ) which send data back to hko every minute. the air is also sampled at these sites to cover the inhalation pathway. to enable early response, an automatic gamma spectrometry system at ping chau, the station closest to daya bay, continuously samples the air, carries out measurements and transmits the results to hko, all automatically
該網路由十個固定監測站所組成，不停地測量香港境內空氣及土壤中放射性物質的直接照射，並每分鐘實時把測量結果傳回天文臺總部。此外，每個監測站亦會抽取空氣樣本，監測呼吸途徑中放射性物質。為了在發生事故時能盡快作出應變，天文臺在香港最接近大亞灣的平洲設立了一套自動伽馬譜法系統，不停地收集空氣樣本，作實時實地的輻射測量，並將測量結果全自動地傳送回天文臺。 -
