阴天的

Above his head, there was no aureole. On his face, there was no charming smile. There was even no sunshine coming through the window springkling on our bodies.That was because it was cloudy that day.

他的头上没有光环；他的脸上没有迷人的微笑；也没有柔和的阳光透过窗子撒在我们的身上，因为……那天是阴天。

After the review of the previous studies on the models of sky luminance distribution, it is the first that this thesis make the systematic study of the pseud-overcast sky luminance distribution by two characteristics of the maximum sky luminanace element and the luminance lapse rate with that the all of sky luminance distribution is determined. Through discussed, these methods and results on pseud-overcast sky study are suggested to be valid of the standardization of intermediate skies in this thesis.

在较为系统地分析了前人有关天空亮度分布模型的基础上，首次利用天空最大亮度元和亮度变化率二个确定天空亮度分布的特征量，对构成中间天空（除CIE全阴天空和CIE全晴天空以外的一切真实天空）之必要部分的似阴天空进行了系统的研究，从而为中间天空的标准化提供了有意义的方法和结果。

Vivipara under different weather conditions all showed two peaks, there still existed differences in the beginning and standing time of their activities, the appearing and standing time of the activities peaks, and the values of the peaks. In fine days, the beginning time of the activities was earlier, and the duration and interval time were longer; while in cloudy days, the duration for activities was shorter, and the appearance frequency of activities peaks was higher. The males devoted more time to activities and appeared more at activities peaks than the females, while the juveniles began activities later and appeared lesser than the adults.

不同性别、年龄和天气条件下胎生蜥蜴的日活动节律均为双峰型，但各种活动开始和持续的时间、活动高峰出现和持续时间以及峰值方面存在差异，晴天时胎生蜥蜴开始活动的时间早，2次活动高峰的持续时间及间隔时间长，而阴天时胎生蜥蜴的活动时间短且集中，在活动高峰时的个体出现率高；雄性比雌性的活动时间长，出现率高，幼体开始活动的时间比成体晚，出现率低。

But in quite is thin and the quitestable water in the clouds, the cloud drop not enough congeals andcombines the growth opportunity, only can cause, the cloudy daycloudy, the congress does not rain.

而在比较薄的和比较稳定的水云中，云滴没有足够的凝结和并合增长的机会，只能引起多云、阴天，不大会下雨。

Illustration: This was shot in a cloud day morning this year winter, after snow, a big group of gooses swam in the lake ,it was so immensity and spectacular, I could not get the rears of them. I wanted to shoot the front of them, bur feared to disterbed the goose alignment.

图片说明：这是我今年冬天雪后的一个阴天上午在密歇根湖所拍，这一大群大雁在湖中浮游，是一支浩浩荡荡的队伍，很壮观，后面还有，没拍下，我想走到大雁正面去拍，又怕等我去时这支队伍的队形散了。

She walks on a blindfold travel and toolate's apopemptic emotion, she dislikes cloudy sky indeed hateraining, blue air always makes her asphyxia.

行走在盲目的旅行和来不及告别的情绪，不喜欢阴天甚至厌恶下雨，忧郁的空气始终让人窒息。

Joseph rattled some fire into the shovel, and went; but he brought it back immediately, with the supper tray in his other hand, explaining that Mr Heathcliff was going to bed, and he wanted nothing to eat till morning.

炉火已经烧成灰烬；屋子里充满了阴天晚上的潮湿温和的空气；如此静，不止是吉默吞那边流水淙淙可以很清楚地听到，就连它的涟波潺潺，以及它冲过小石子上或穿过那些它不能淹没的大石头中间的汩汩声也听得见。

It was the light. It was still the gray-green light of a cloudy day in the forest, but it was clearer somehow.

是光线。虽然依旧是阴天森林里的那种灰绿色的光线，但不知怎么的，的确明亮一些了。

On the morning of February 2, Groundhog Day in Punxsutawney, Phil is invited to step out of his lair. If he sees his shadow, in other words if the sky is clear and bright, local people believe -- or at least they profess to believe -- that there will be another six weeks of hard winter. If Phil casts no shadow because the sky is overcast, the prognosis is for mild weather and an early spring.

在2月2日，也就是彭瑟托尼镇的土拨鼠节的上午，人们请菲尔走出它的窝，如果它能看到自己的影子，也就是说天空晴朗无云，当地人就会相信（或者说至少他们表示相信）未来还有6周的寒冬；如果是阴天，菲尔没有投下影子，就预示着天气温煦，春天早到。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
