exposure duration 中文意思是什麼
exposure duration
解釋
暴露時間-
For the acute exposure duration, there expressed the dose - thresholds and time - thresholds in the effects of cu2 + on the activities of cat, pod and sod in two macrophytes. when the test species were exposed at low dose and for a short period, cu2 + can stimulate activities of antioxidant enzymes. once exceeding the thresholds, cu2 + may inhibit enzymes activities
Cu ~ （ 2 + ）低濃度和短時間內對抗氧化酶有誘導作用，超過一定的閾限會產生抑制作用；金魚藻cat 、 pod 、 sod活性在7天內的最大抑制率與暴露cu ~ （ 2 + ）濃度呈顯著正相關。 -
Theoretical models were used to predict the effects of microcrack - density to effective tensile modulus of cf / ep laminates for long - term duration exposure for it difficult to get from tests. a uniaxial zero - expansion model was established based on the analysis of thermal stress and the coefficient of thermal expansion of the laminates
由於受到試驗周期的限制，對于長期暴露于空間環境中的層合板材料，其有效拉伸模量很難用試驗方法直接測量，本文採用理論模型進行分析。 -
The incubation period, which is the time from exposure to a causative agent to onset of disease, is particularly important as it forms the basis for many recommended control measures, including contact tracing and the duration of home isolation for contacts of probable sars cases
潛伏期，即從接觸致病體到開始發病的時間，因它形成許多推薦的控制措施而特別重要，包括跟蹤接觸史和對sars疑似病例的接觸者的家庭隔離時間。 -
The inactivation rate depends directly on exposure temperature ( 37, 39 ), and it is important to investigate a method of protein stabilization and to estimate the shelf - life of the strip, i. e., the duration for maintaining 90 % of the initial activity
失活速度直接決定於暴露的溫度，因而研究穩定蛋白的方法和測量免疫條的貨架壽命，即保持最初活性90的持續時間，是很重要的。 -
Toluene and m - xylene are not cancer - causing substances. their effects on health depend on the level one is exposed to and the duration of exposure
甲苯和間二甲苯並非致癌物質，對人體影響需視乎個人處于甲苯和間二甲苯成份的水平和時間。 -
An enhancement of early musical exposure on the behavioral performances of sound duration discrimination in rats
早期音樂暴露增強大鼠分辨聲音時程的作業能力 -
Apart from the concentrations and chemical properties of the pollutants, the person s age and general state of health, the duration of exposure, factors such as the weather condition and the distance from the emission sources also affect the nature and extent of the health effects observed
除了空氣中污染物的濃度與化學特性之外，有關人士的年與一般健康狀況接觸污染物的時間長短氣候情況以及排放源頭與接觸者之間的距離等，都會對健康構成不同的影響。 -
In accordance with advice given by the director of health, the effects of benzene on health depend on the level one is exposed to and the duration of exposure. brief exposure ( five to ten minutes ) to very high levels of benzene in air ( 10, 000 to 20, 000 ppm ) can result in death. lower levels ( 700 to 3, 000 ppm ) can cause drowsiness, dizziness, rapid heart rate, headaches, tremors, confusion and unconsciousness
當人處于高水平苯成份（百萬份之一萬至百萬份之二萬）的地方歷時5至10分鐘可致死亡；而處于含有低水平苯成份（百萬份之七百至百萬份之三千）的地方可使人昏昏欲睡、暈眩、心跳加速、頭痛、顫抖、思想混亂和失去知覺。 -
Carbon monoxide reduces the oxygen carrying capacity of red blood cells. the health effects depend on the duration of exposure and the concentration of carbon monoxide inhaled
一氧化碳會降低紅血球的帶氧能力，它對健康所造成的影響則視乎身體接觸一氧化碳的時間長短，以及吸入一氧化碳的濃度。 -
Experimental dissociation of exposure duration ' s effect on the attentional blink
刺激持續時間對注意瞬脫影響的實驗分離現象 -
Other factors that increase the likelihood of infection are longer duration of exposure, indoor exposure, and contact with an indiidual who is smear positie
其它可增加感染的因素有長時間的暴露，室內暴露及與塗片陽性者接觸。 -
Such fields allow more information to be incorporated in the exposure fields used in epidemiological studies, rather than having to assume that ambient exposure is the same across a whole city and / or that individuals remain at the one location for the duration of a study
透過這種方法所得到的濃度區域讓更多資訊能夠與暴露評估結合，並且可以應用到流行病學研究上，而不需要假設在研究期間整個城市或個人之空氣暴露是相同的。
