查询词典 exposure

A classic example of an intentional imperfect exposure is when a photographer intentionally overexposes a portrait of an older woman by a full f-stop or more to minimize facial lines and wrinkles. While the exposure is intentionally imperfect, it complements the subject and provides a pleasing image.

比如，这里有一个刻意使曝光不完美的典型例子：一个摄影师刻意将光圈数调到最满或更多来使一张老妇人的图片上显现最少量的线条和皱纹，使其曝光过度，这种曝光设置是不完美的，但它赞美了被摄体，并且达到了很好的视觉效果。

Morphological and flourescent changes were assessed using confocal microscopy in whole-mount organ of Corti preparations. Results (1) After the animals were exposed to broadband noise at 122 dB SPL in 4 h/day for 2 days, both apoptosis and necrosis appeared in OHCs. The single strand DNA in apoptotic OHCs were observed both in guinea pigs and mice.(2) In normal OHCs, EndoG was distributed outside of nuclei. EndoG translocated from outside to inside of the nuclei in both apoptotic and necrotic OHCs following noise exposure.(3) The MNNG cochlear perfusion and noise exposure both caused the transloctation of AIF from the mitochondria to the nuclei. The translocation of AIF took place in both apoptotic and necrotic OHCs.

The results showed as followed :（ 1 ） The most important factor of atmospheric general circulation controlled and influenced the immigration of WBPH＇s populations was the patterns and the tempo-spatial changes of potential height field on 850hPa isobaric surface,（2） There were relative coincident air streams with a northern exposure on 850hPa isobaric surface during the migrations northward of WBPH and there were concurrent airflows with a southern exposure on 925hPa isobaric surface during the migration southward.

The Zn concentration in leaf and leafstalk increased with increasing Zn supply from 0 to 160 mgL^(-1), but had no increase or even decreased when the Zn supply was higher than 160 mgL^(-1). The Zn concentration in root exhibited a positive correlation with Zn supply and its exposure time, and the kinetic curve of Zn uptake fitted linear-quadratic model, i.e., fast linear uptake first and slow saturation uptake later, with the dividing point at about 1-2 hours' exposure, which could be related with the Zn adsorption on root cell wall and the Zn transportation across the cell membrane.

在0160 mgL^(-1) Zn处理下，植株叶片和叶柄Zn含量随Zn处理水平的提高显著增加，Zn浓度大于160 mgL^(-1)后，植株叶片和叶柄Zn含量不再随介质中Zn浓度的提高而增加，根系含Zn含量与介质中的Zn浓度和培养时间呈正相关，且根系Zn吸收动力学曲线具有二型性，即开始为快速的线性吸收，随后是较缓慢的饱和吸收，两者分界点约在12h，这可能分别与根细胞壁吸附Zn和Zn跨根细胞膜运输有关。
