清晰度

According to the image evaluation of the absolute central moment of clarity of images, multiple images at the same time read, and gives its definition curve.

详细说明：根据图像的绝对中心矩评价图像的清晰程度，同时读入多幅图像，并给出其清晰度曲线。

Results Compared with conventional ultrasound,sonoCT could suppress the reverberation artifacts in bile duct and gallbladder obviously.Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.Thus,sonoCT raises the reliability of biliary tract tumors diagnosed by ultrasound.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

I especially favor EL84 from Yugoslav to match SR325, for the performance of vacuum tube is given full play. Besides transparent definition and infinite detail, the melody is alluringly sweet.

笔者尤其喜欢用南斯拉夫出产的EL84来配搭SR325，皆因该真空管的表现最为全面，除了在保留透明的清晰度与无限细节外，所发出馥郁芳醇的甜美度更有使人"一听触电"的万股毒力！

Three digital inputs makes it easy to connect all of your high definition sources simultaneously, and the two 12V triggers can accommodate an anamorphic lens and motorized screen.

三个数字输入，可轻松连接你的所有来源的高清晰度，同时，这两个12V的触发器可以容纳变形镜头和电动屏幕。

An optical system of measuring system is constituted by a illuminating system and a magnifying system. The illuminating system adopts a far center illuminating mode to make the illumination unified. The magnifying system all adopts object far center optics path to eliminate the error for out of focus. The objective is a plan and apochromat to make image clear. The operator adjusts focus with parameters provided by computer.

论文分析了纤维细度测量系统的光学系统：照明系统采用远心柯勒方式，实现物面的均匀照明；成象系统采用物方远心光路，减少离焦对纤维细度测量的影响；物镜采用平场消色差物镜，消除因为象差引起的图象变形和不清晰，为纤维细度的高精度测量奠定基础；在图象清晰度判别中采用计算机计算参数结合人工调整的方法，既保证结果的客观性，又使系统简化。

And unlike previous prototype 3-D televisions, which have been small and have provided only modest picture quality (because a lot of detail is lost in the process of adding apparent depth to 2-D images), it can be manufactured in conventional television sizes to provide pictures of impressive clarity.

和之前小而昂贵并且图像质量一般(因为之前的三维电视在向二维的画面添加深度时丢失了很多数据)的三维电视不同，它能被制成常规的大小，并且能提供令人印象深刻的画面清晰度。

Arranging them to form the arc of a circle bothclarifies and simplifies their readability, while lending this piece adistinctive and resolutely DeWitt character.

其清晰度、弧形布局不仅简洁明快，还赋予这款腕表充满 DeWitt 品味的特色。

All of these problems concern articulation, the clarity of speech.

所有这些问题都与说话的清晰度有关。

Results:All of 16 children's score of articulation increased from 49.9% to 88.2% in average.

结果：16名患者经过平均25 d的强化训练后，语音清晰度从平均49.9%提高到平均88.2%。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
