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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
