In the first part of this thesis, Stress relaxation method set up in the software of DMA was used to perform the aromatic and aliphalic (D2192-BAPP) PI film stretching process. To study the optical anisotropies property to the light leakage from the crossed polarizers, we put the stretched samples into one set of crossed polarizers and as expected, the stretched PI films could reduce the light leakage at view angle of ±45 deg, and exhibited a visually observed compensating property of an A-plate. No color shift wasobserved, and the birefringence was very uniform. These results prove a uniform birefringence can be obtained by a stretched process for PI films.

首先，我们以动态机械分析仪的应力缓和模式对芳香族FDA-BAPP PI及脂肪族D2192-BAPP PI薄膜进行拉伸实验，并将拉伸后的PI薄膜置於一组相互交差的偏光片中观察其光学异向性，发现拉伸后的PI薄膜试片可以降低在±45o视角的漏光的效果，展现出如同A-Plate的光学补偿特性，所显现的光学补偿效果相当的均匀而且没有色偏的情形发生，证实以拉伸方法可以造成PI薄膜很均匀的双折射效应。

This paper briefly reviews the operation principles and features of mechanical sight, optical sight, electrooptical sight and integrated sight. The status of mechanical sight, traditional optical sight, lowlightlevel night vision sight, new electrooptical sight and integrated sight equipped in different nations worldwide is given. The development status and parameters of various typical electrooptical sights as well as simple day and night firecontrol systems are described. It is pointed out that mechanical sight and optical sight are still necessary for future light weapons. However, electrooptical sight shall prevail in equipment procurement, and light weapon sight equipped in the future shall be the integrated electrooptical sight.

This one is fantastic and doesnt make my skin look orange or pink, im using the light cream color which is a bit too light for me during the summer but will be a great match for winter!

这是荒唐的和doesn't让我的皮肤外观橙色或粉红，利用免疫参照奶油色这是一个有点轻，我在夏季，但将是一个伟大的比赛冬季！

Directional Light Mapping enables the static shadowing and diffuse normal-mapped lighting of an unlimited number of lights to be precomputed and stored into a single set of texture maps, enabling very large light counts in high-performance scenes.

定向光贴图技术提供给静态光影和和扩散法线贴图光照几乎无限的灯光数量以作为预渲染或者是存储在一个单独的贴图套件中，在高精度效果场景中提供大量的灯光效果。

The six cucumber materials with different low temperature tolerance were selected to be cultured in the artificial lighting incubator for 14 d under day temperature of 12 ℃,night temperature of 8 ℃,light of 8 h,light intensity of 30 μmol/(m2·s)(about 2 000 lx)and the abscisic acid,the growth hormone and the gibberellic acid(GA3) of cucumber leaves were ...

结果各黄瓜材料叶片中ABA和GA3含量均有不同程度增加，耐低温性材料越强，其增加的幅度越大，而叶片中IAA含量变化则不同，其中耐低温较强的材料增加的幅度较大，而耐低温较弱的材料有所降低，耐低温性中等的材料略有增加。内源激素含量与耐低温性的关系密切，可作为黄瓜耐低温性的间接鉴定指标之一。

Likely triggered by interactions with nearby galaxy M81, M82's intense star formation activity appears to be blowing out immense clouds of dust and PAHs extending nearly 20,000 light-years both above and below the galactic plane. M82 is about 12 million light-years away in the constellation Ursa Major.

或许是由于附近M81星系相互作用引发的，M82剧烈的恒星形成活动看上去就像正在膨胀的巨大尘埃云，多环芳香烃化合物在星系盘面上下延伸了将近2万光年。M82位于距离我们1，200万光年远的大熊星座内。

If light was treated as being in a side to side action or 'transverse motion' then birefringence could be attributed to a light wave rather than the particle or corpuscular theory of Newton.

如果光被视作一个方方的行动或'横议案'然后双折射可归因一个光波粒子或红细胞而非牛顿理论。
