这些解毒能力较差的婴儿在加上出生后多次的疫苗注射暴露到的汞，可能造成严重的后果，或是已接近危险暴露量的门槛。

Each wavelength of optical radiation has an associated threshold retinal exposure level that must be exceeded in order for retinal damage to be observed - shorter wavelengths are more effective in that less energy is needed.

对应每种波长的光都有一个极限值，超过这个极限值才能使视网膜受到损害。对於较短波长的光幅射，这个极限值的能量强度较低。

By means of numerical simulation in different heat conduction processes,the steady-state temperature field in upper arm skin tissue,the temperature distribution and the burn depth threshold after 15 s exposure to a heat source at 90 ℃,the su...

通过数值模拟，获得了不同皮肤组织结构模型下上臂皮肤组织内的稳态温度场和90℃高温热源作用15 s后皮肤组织内的温度分布，以及皮肤组织热损伤深度的变化、常热流作用下皮肤组织表面的温升曲线和表面绝热条件下皮肤组织内的稳态温升分布。研究结果表明，皮肤组织的多层传热数学模型更能真实地描述皮肤组织内的传热过程，因此值得在实际工作中推广应用。

By means of numerical simulation in different heat conduction processes, the steady-state temperature field in upper arm skin tissue, the temperature distribution and the burn depth threshold after 15 s exposure to a heat source at 90℃, the surface temperature rising of skin subjected to a surface-applied constant heat flux, and the steady state temperature elevation distribution under the thermal insulation, are obtained.

通过数值模拟，获得了不同皮肤组织结构模型下上臂皮肤组织内的稳态温度场和90℃高温热源作用15 s后皮肤组织内的温度分布，以及皮肤组织热损伤深度的变化、常热流作用下皮肤组织表面的温升曲线和表面绝热条件下皮肤组织内的稳态温升分布。

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.

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。

The updated AAD statement now emphasizes that there is no scientifically proven safe threshold for exposure to the sun or indoor tanning devices that optimizes vitamin D synthesis in the skin without increasing skin cancer risk.

最新美国皮肤病协会的这份声明特别强调了一点，就是目前还没有确定通过日晒或是室内晒黑装置来在皮肤内自然合成维生素D而不增加皮肤癌患病风险的安全阈值。

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 swine influenza virus.

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，微生物，如甲型（H1N1）流感病毒没有暴露限值，如职业接触限值，因此，虽然佩戴呼吸防护口罩能够帮助降低暴露水平，却无法保证使用者绝对不接触甲型（H1N1）流感病毒，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。

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。

Because the threshold exposure levels for photic damage to the retina at each wavelength of the optical spectrum are well known, it is fairly simple to calculate the maximum permissible filter transmittance that will provide adequate retinal protection from sunlight.

由於每种波长光线的极限值都已被测定，所以要计算出安全太阳滤镜最高允许透光率是很容易的。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
