中途曝光：由极端的过度曝光所造成的全部或局部影像倒转的情况，在显影中途，作全面曝光，亦能获得同样效果。

The present thesis showed that root elongation of alfalfa (Medicago sativa L.) during a 24-h period was inhibited by 80% by the exposure to 5 umol L-1 Al and its roots was obviously stained by eriochrome cyanine R; however, the roots of stylo need to be exposure to 30umol L-1 Al in order to get obviously stained with its root elongation was inhibited by 68%, which shows, for stylo, its ability of tolerance to aluminum is strong.

本研究发现，5 μmol L~(-1)AlCl_3使紫花苜蓿根长抑制80.0％，铝处理后的根尖被铬天青明显染色，而柱花草经30 μmol L~(-1)的AlCl_3处理后方观察到根尖明显染色的现象，根的伸长受抑制68.0％，表明柱花草抵御铝毒能力较强。

Direction of the human radial artery by the cubital fossa at the midpoint of the bottom of 2.5CM connection to the radial styloid process is not a vertical direction of blood vessels, a large number of data measurement, based on the basis of the treatment instrument designed to meet the ergonomic parameters of the radial artery into the actual trajectory of the laser positioning warehouse ladder-type arrangement, thus ensuring the laser projection domain and the radial artery into a high degree of matching of the laser spot can be an accurate projection exposure to the region in the radial artery through the line to avoid exposure is invalid.

人体桡动脉的走向是由肘窝中点下方2.5CM处至桡骨茎突的连线，并非是一条垂直走向的血管，在大量数据测量的基础上，本治疗仪依据人体工程学参数设计了符合桡动脉血管实际走向轨迹的激光定位仓阶梯型排列，从而保证了激光器投影域与桡动脉走向的高吻合度，使激光投影的光斑能准确照射在桡动脉循行区域，避免无效照射。

According the characteristic of tensor filed can externalize the local exposure information in image,this paper introduces an image de-noising method which uses the local exposure information of tensor field to control filter.

郑州大学电气工程学院，郑州 450001摘要利用张量场能体现图像各个局部的朝向信息的特点，提出利用张量场局部朝向信息控制滤波器对图像进行去噪处理的方法。

Based on the comparisons of PEG exposure from PEGylated biological products and the exposure of PEG associated with toxicity in humans, the therapeutic index is large(approximately 600-fold or greater).

基于聚乙二醇酯化的生物制品会游离出聚乙二醇，以及游离的聚乙二醇所具有的对人的毒性，该生物制品治疗指数大（大约600倍或更高）。仅供参考，呵呵。

At this point the exposure time is the first time exposure time of l ~ 2 times.

此时的曝光工夫可以是第一次曝光工夫的l～2倍。

Phase correlation and then reaches image mosaic by graph cut and poisson image fusion.graph cut is used to find a globally optimized seam-line for deghosting while poisson image fusion is used to realize smooth mosaic without exposure difference.a new weight calculation method based on the statistics of guadient direction histogram is presented here in order to robustly realize graph cut.an edge transition poisson image fusion method is also proposed to reach exposure difference removal

该方法在相位校正的基础上将图切割和泊松融合相结合实现拼接，图切割用于搜索全局最优的缝合线以去除鬼影，泊松融合用于曝光差异的处理。本文给出新的基于梯度方向直方图统计的权值计算方法，实现稳定的图切割。另外，本文还设计出重叠过渡的泊松融合方法，较好地完成图像合成。

But shooting the sun is tricky. On a clear day, the sun is so bright that your camera's meter will tend to underexpose everything else in the frame. Shoot in manual mode, or take a reading without the sun in frame, depressing the shutter button halfway to hold the exposure, then reframe before you shoot. If you're shooting film, bracket a lot to make sure of getting the exposure you want.

把太阳放在构图中以表达沙漠中的高温和荒芜，但拍摄太阳比较麻烦，晴空下的阳光影响相机的感光计，以至于构图中其它部分曝光不足，为避免这种情况，要启用相机的手动模式，或者是将太阳从构图中排除后，半按下快门固定曝光值，然后重新选择有太阳的构图，将快门按到底。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
