在近年來提出的基於質點運動學原理的單站無源定位理論基礎上,本文第二章提出了幾種在角度測量的基礎上增加角度變化率及相對運動的離心加速度等運動學參數的單站無源測量模型,並對它們進行了分析和模擬;第三章分別對利用角度及其變化率信息定位和利用離心加速度信息定位的可觀測性進行分析並得到了相應的可觀測條件;第四章針對傳統擴展卡爾曼( ekf )方法的缺點,提出了一種修正協方差的擴展卡爾曼濾波( mvefk )方法,並將其和ekf 、 mgekf 、 iekf等常用的單站無源定位濾波方法進行了性能模擬比較;第五章通過引入雷達機動目標跟蹤方法和模型,提出了利用角度及其變化率對機動輻射源跟蹤的多級噪聲自適應方法和imm方法;第六章主要對角度變化率和離心加速度參數的獲取技術進行了研究,提出了幾種高精度測量脈沖序列多普勒頻率變化率的方法。Material energy can be transformed into radiant energy only in units of a certain size.
物質能量只能以一定大小的單位轉變為輻射能量。Workers whose annual dose is likely to exceed 6 msv are required to be classified as radiation workers. this requires that their exposure be measured and regularly monitored and that they be subject to periodic medical examinations
全年吸收劑量有可能超過六個毫西韋特單位的人士,便被列為在輻射下工作的人士,需接受輻射接觸量的量度和定期監察,並需定期進行身體檢驗。It can be seen from the measuring results that the deviation is litter than 10. 1 % when the estimate value of the nature radiation ' s kerma is compared to the average value gotten by standard ionization chamber, and the deviation is less than 16. 2 % when the estimate value of two groups of tlds those measuring radiation in laboratory is compared to the conventional true value in standard radiation field
從參比單位給出的測量結果看出,天然環境輻射比釋動能測量的評定值與標準電離室測量的平均值比較,其偏差好於10 . 1 % ,實驗室射線照射組兩組熱釋光劑量計( tld )測量評定值與標準輻射約定真值偏差好於16 . 2 % 。Energy absorbed per unit mass of the material
單位質量物質吸收的電離輻射能量。The amount of radiation energy transmitted per unit time
每單位時間內所傳送的輻射能量。The amount of radiation energy fell on unit area per unit time
每單位時間內照射在一平方米面積的輻射能量。It is therefore completely impossible to avoid ionising radiation altogether. the average background radiation as about 2 msv per year
