查询词典 threshold exposure

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。

By acquired the average value of all pixels, the number of saturated pixels and severe underexposure pixels, the control mode, the number of exposure, integrating time of each exposure and composition algorithm is determined in real-time.

通过获取加权光强平均值以及饱和像素数目和严重欠曝光像素的数目，对场景光强进行评价，对采样控制方式、次数和积分时间和组合算法进行实时控制，完成30万像素版图设计验证和FPGA验证。

For a given total exposure dose, the diffraction efficiency of the diffraction grating first increases and then decreases with increasing the exposure intensity, and this effect becomes more remarkable with increasing the unsaturation concentration of polymeric binders.

高分子感光膜的衍射效率随着高分子载体折光率的增大而提高，同时其饱和曝光剂量随着感光膜体系中丙烯酸双键含量的增大而降低；单体良好的迁移性能及其与高分子载体良好的相容性都将大大提高感光膜的衍射效率。

For one month after exposure, TBT could induce the depletion of colloid and vacuolation. And for two months after exposure, the incidence of follicle malformation also significantly increased, the relative transverse thyroid gland area and follicle area decreased sharply, and the number of follicle did not show any significant changes.

结果表明，TBT暴露1个月能引起爪蟾甲状腺滤泡胶质减少甚至空泡化，暴露2个月后，甲状腺滤泡的变形率也显著增加，相对甲状腺横截面积和滤泡面积仅为平行对照的35.3%和45.6%，而滤泡数目没有明显变化。

When the exposure indicator is displayed in the viewfinder display, the exposure compensation is set.

当曝光指示灯出现在取景器显示中，曝光补偿被设置。

I want to be a big fish in a small pond.

我要做一条在小池塘里的大鱼。

While the software functioned well, we did not feel the same about their customer support!

虽然该软件运行良好，我们没有同样的感觉他们的客户支持！
