查询词典 exposure-meter

However,unlike most industrial particles there are no exposure limits, such as Permissible Exposure Limit or Threshold Limit Value, established for biological agents such as SARS. Therefore, respirators are not a guarantee that the user will not contract SARS. Respirators may help reduce exposures

然而，和绝大多数工业环境中存在的颗粒状污染物不同的是，SARS病毒并没有暴露限值，因此，佩戴防护口罩虽然能够帮助降低其暴露水平，却无法保证使用者绝对不接触SARS病毒，即不排除存在暴露的可能，不排除受感染、生病甚至死亡的可能。

After summarizing the information of Life Cycle and Health Risk Assessment, also the cost of MTBE is lower than ethanol, it shows that under manifold paths of exposure, the threshold value of cancer is without the acceptable range (10-6). The inhabitant will have high health hazard for the exposure of MTBE.

研究显示，根据生命周期评估结果，生产MTBE在能资源投入皆比燃料酒精占优势，唯需考虑MTBE属不可再生资源，而燃料酒精不但是可再生资源，且对温室气体减量具有正面助益。

Results: 47 enterprises were using N-Hexane and 554 workers exposure to N-Hexane; The concentration of N-Hexane in 3 enterprises were exceeded the Occupational Exposure Limit; Achilles's tendon reflex of 3 workers were disappeared; and most of enterprises lacked of occupational health management and protection measures.

结果：昆山市共有47家企业使用正已烷，接触人数共554人；有3家企业正已烷浓度超标；职业性健康检查人数共54人，其中有3人腱反射减退或消失；多数企业职业卫生管理和防护措施落实不到位。

In this paper, motion model of star spot which is combined with the effect of CCD noise has been established. The centroid accuracy of the star spot affected by sub-pixels arithmetic and CCD noise were analyzed at different exposure time with CCD47-20 chip, and the optimum exposure time was calculated.

建立星敏感器星点像移模型和CCD噪声影响模型，分析了星点质心定位精度与曝光时间的关系，并以CCD47-20为例，对星敏感器的曝光时间进行了优化。

Exposure time is too long, a small dot, the exposure time is too short, relative to the plate.

曝平工夫太不幼，网点面积小，曝平工夫太不幼，印版不绝对给深。

By comparison of long-term exposure with long-term immersion, the release amount of ammonium, nitrite, nitrate and dissolved phosphorus into the overlying waters from the sediments were increased during the reflooding after long-term dessication, reflecting that long-term exposure stimulated sediments as a releasing source of nutrient and accelerated the biogeochemical cycle of nutrient in the tidal flat ecosystem.

通过对比分析发现，长期暴露之后能够增加沉积物向上覆水体释放NH〓-N、NO〓-N、NO〓-N和TDP，显示了长期暴露加剧了沉积物作为营养盐的源效应，并且加速了潮滩生态系统内营养盐的生物地球化学循环过程。

In the present study, CHL cells were cultured routinely in MEM medium for 3 days. Then the cells were treated with sham exposure , 0.4mT 50 Hz sinusoidal MF , 0.4mT noise MF and the combined noise and 50Hz MF for 3 min and 15min, respectively. After exposure, the cells were lysed, and the proteins were extracted.

实验中，将中国仓鼠肺成纤维细胞分别经0.4mT工频磁场、等强度的噪声磁场、工频磁场与噪声磁场的复合磁场辐照及假辐照处理3min和15min后，裂解细胞，提取细胞蛋白质，以Western印迹技术，测定并比较细胞内SAPK磷酸化的变化。

However, it is important to understand that proper use of respirators only reduces your exposure to particles and does not prevent the risk of some exposure.

然而，重要的是要能理解，正确使用呼吸器只能降低您对颗粒物的暴露水平，但不能完全把风险消除掉。

This chapter has taken the late Qing Dynasty imperial examination and officialdom vocabulary semantic field as example,and analyses the general picture of vocabulary semantics in The Records of Officialdom Exposure by modern Chinese semantics,and analyses and contrasts the synonyms in The Records of Officialdom Exposure.

第四章：《官场现形记》词汇语义分析，以晚清科举和官场词汇语义场为例，运用现代汉语语义学的理论分析了《官》中词汇语义的概貌，并对《官》中的同义词进行了分析、对比。

Duration of antiviral chemoprophylaxis post-exposure is 10 days after the last known exposure to an ill confirmed case of swine influenza A (H1N1) virus infection.

暴露后抗病毒药物预防的持续时间为10天，在最后已知暴露在一例确诊感染A（H1N1）型猪流感病毒的病人之后。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
