These mystifying clouds are called Polar Mesospheric Clouds, or PMCs, when they are viewed from space and referred to as "night-shining" clouds or Noctilucent Clouds, when viewed by observers on Earth.

这些神秘的云彩被称为中间极地云层，或市局当他们从空间和被称为&夜间闪光&或云夜光云观看时，由观察员在地球上。

Noctilucent clouds are ragged extensions of a more widespread and more permanent layer which forms over the summer polar area at the mesopause.

夜光云是在夏季极地中圈顶之上形成的更广泛更持久的层的参差不齐的延伸。

Noctilucent Clouds or Polar Mesopheric Clouds: This is an extroadinarily rare cloud formation that occurs out on the verge of space between 82km to 102 km from the earth's surface.

夜光云层又被称为极地中层云：这种云层极其罕见，只形成于距离地表82-102公里的大气空间边缘部位。

In order to obtain viable tetraploids, which remains a major challenge worldwide, research on spindle organization and chromosome behavior was carried out mainly in zhikong scallop, Chlamys farreri, a typical commercially important species which is being cultured in North China Sea. Immunofluorescent technique and laser scanning confocal microscopy has been developed for observation of both microtubule organization and chromosome segregation. Orcein squash method was also used for chromosome observation. A series of complicated configurations of the meiotic spindle and associated patterns of chromosome segregation, including tripolar and seperated bipolar segregation, were found in developing eggs following the inhibition of the first polar body.

为了攻克可存活四倍体人工培育技术的国际性研究难题，本研究选取了我国北方海区的典型经济贝类栉孔扇贝为主要研究对象，建立了一套免疫荧光染色和激光扫描共聚焦显微技术，结合使用染色体地衣红压片观察技术，对第一极体受抑制的受精卵的减数分裂纺锤体装配、染色体分离动态进行了研究，发现了一系列特殊的纺锤体装配及相应的染色体分离行为，包括三极分离、独立二极分离等分离类型，从亚细胞水平上阐明了四倍体形成的细胞学机理。

Figure 1 shows the locations of the Diviner LCROSS impact swaths overlain on a grayscale daytime thermal map of the Moon's south polar region.

图一显示了&预言家&观测到的月球轨道探测器的撞击痕迹在月球南极地区日间热成像灰度图上所覆盖的区域。

In short,the improvement of surface hydrophilicity is attributed to both the formation of polar oxygenous group and the increase of surface roughness.

可见，聚丙烯表面亲水性的提高来源于含氧基团数量的增加和表面粗糙度的增加。

From FT-IR we think that the hydrogen bond between the polar oxygenous group on the thin film surface treated with plasma and acetone molecules would enlarge the distance between the carbon black particles, resulting in the addition of the electrical resistance, then the response behavior of the thin film to acetone was improved greatly.

我们通过FT-IR研究认为，等离子体处理后，薄膜表面引进的极性含氧基团与丙酮分子之间氢键的形成会增大炭黑粒子之间的距离，导致了薄膜电阻的极大增加，使薄膜对丙酮蒸气的响应得到很大改善。

This paper proposed a new type of feature extraction arithmetic for texture image, based on parametrical log polar translation. This arithmetic is robust to geometric distortions.

提出一种细化参数的对数极坐标变换图像纹理特征提取算法，可以有效地消除旋转、缩放和平移等几何形变的影响。

The polar lipid s are found almost entirely in cellular membranes (phospho lipid s being the main components of the bilayer) with only very small amounts in depot fats.

极性油脂几乎全部存在于细胞膜，只有很少量存在于贮存脂肪中。

The polar lipids are found almost entirely in cellular membranes (phospho lipids being the main components of the bilayer) with only very small amounts in depot fats.

极性油脂几乎全部存在于细胞膜，只有很少量存在于贮存脂肪中。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
