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。

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。

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。

A good flexible language, can be reprinted for many times, the website that can let you causes the attention of Baidu in the exposure inside short time, and should appear what the form of your website exposure is like Alexandrine face place to say only network address can.

一篇好的软文，会被多次转载，可以让你的网站在短时间内曝光引起百度的注意，而你的网站曝光的形式如同上面所说的只要出现网址即可。

Although the researchers found no direct link between the prevalence of any birth defect and the level of exposure, their calculations revealed that exposure to high levels of by-products substantially increased the risk of three common defects: ventricular septal defects, cleft palate, and anencephalus (where neural development fails, resulting in the absence of a major portion of the brain, skull, and scalp).

虽然研究人员发现，之间没有直接的联系流行的任何出生缺陷和暴露水平，他们的计算显示，暴露在高层次的，由产品大幅增加的风险三个共同的缺陷：室间隔缺损，腭裂，及anencephalus （如神经发育失败，导致在缺乏一个主要部分的脑，头骨，和头皮）。
