常見例句The first step is to determine the unit-time reference dose rate. 第一步要確定單位時間參考劑量率。A radioactive particle moving in a blood stream causes transient changes of dose rate near its path. 當(dāng)一個放射性物質(zhì)在血流中移動時在它的路徑附近引起劑量率的瞬間變化。However, since the dose rate is steadily decreasing during the exposure, appropriate allowance for this must be made. 可是,由于在輻照過程中劑量率逐步下降,所以必需進行適當(dāng)?shù)男拚?/li>If the dose rate at any time is known by actual measurement, the value at any other time can be estimated. 如果通過實際測量已知任意時刻的劑量率,則可計算出任何其它時刻的數(shù)值。A method for calculating cosmic radiation dose and dose rate to aircrews in atmosphere is presented in the paper. 本文介紹了一種在大氣層中民航飛行高度上宇宙輻射有效劑量率和飛行航程中機組人員所受有效劑量的計算方法。The simulating results agree with the experimental results at different absorbed dose rate. 理論模擬結(jié)果與實際不同劑量率輻射實驗結(jié)果符合得很好。 返回 dose-rate
