查询词典 lethal dose

After four weeks, the results showed that only the rats that got the 500-milligram daily dose of garlic were resistant to the cholesterol-raising effects of their diet. The 500-milligram dose of garlic was also associated with an increase in the time it would take for blood to clot. Heart attacks and strokes are primarily due to blood clots that block blood flow supply to the heart and brain.

四个星期之后，结果显示，只有获得每日500毫克剂量大蒜的老鼠，对于他们饮食中的胆固醇增加的效果有抵抗能力，500毫克大蒜的剂量也与血液要凝结的时间增加有关；心脏病发与中风主要是由于血液凝块阻塞了心脏与脑部的血流供给。

In order to make the uncertainty of the dose index measurement in the head phantom reasonable for the medical diagnostic X-ray radiation sources of the computed tomography, the measurement uncertainty components were analyzed according to the mathematical model for the computed tomography dose index test method with a 100 mm ionization chamber.

摘 要：为了使医用诊断计算机断层摄影装置X射线辐射源在模体中的剂量指数测量结果的不确定度评定合理，基于用带有100 mm长杆电离室的积分剂量仪测量CT剂量指数的数学模型，对其测量不确定度来源进行分析，列出了方差、灵敏系数及标准不确定度的计算公式，从而给出了CT剂量指数测量的合成标准不确定度和扩展不确定度。
