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。

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。

With objective detection threshold timeas the prime exposure time and figues (Ara-bic figures) and numerals in Chinese andGermans as stimili,we compared the primingeffects of Chinese and German under patter-ned masking.

本文采用客观觉察阈值作为启动刺激呈现时间、以数字和数词(以中、德两种文字写出的数词)为刺激比较研究了在掩蔽刺激条件下中国与德国被试的启动效应。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
