first image

• The first image is a reference drawing of the basic normal 4 - chamber view ( figure 2 ) , with the cardiac apex and the descending aorta on the left and the axis of the heart at about 45 from the midline
  图2是基本的正常四腔心切面的参考示意图，心尖和降主动脉在左侧，心脏的轴线和中线呈45 。
• The second image is generated the same way as the first image except that it is displayed in its default dimensions the tag to generate the second image does not have dimension attributes
  按照与第一个图像相同的方法来生成第二个图像，只是以缺省尺寸来显示第二个图像（生成第二个图像的标记没有尺寸属性） 。
• While processing sports images , the first images of joints made man were regarded as presupposition , and the following analysis of joints were done by computers , which were faster and more accurate
  分析过程中，首帧图像的关节位置由人工输入，作为先验知识，以后的分析过程由计算机自动进行，分析结果迅速准确。
• However , if the plane of the selector aperture is not precisely coplanar with that of the first image , then diffracted rays originating from outside the area defined by the aperture may contribute to the diffraction pattern
  然而，如果选择孔的平面与第一次成像不是正好共面，源自孔指定区域外部的衍射线可能影响衍射模型。
• As mentioned above , to image the diffraction pattern it is necessary to reduce the power of the diffraction lens by altering the current through the lens coils from the value used to form an enlarged image of the first image
  如上所言，要成像衍射模型就必须缩减衍射透镜的能量，通过改变从已有形态到形成第一映像的放大映像过程中穿过透镜圈的能量实现。
• An inverted image is formed in the first image plane and the three subsequent lenses in the namely the diffraction lens , the intermediate lens and the projector lens are used either to magnify this image or to magnify the diffraction pattern
  在第一映象平面出现一个倒的图象，随后的第三透镜也就是衍射透镜，中间的透镜和投影透镜被用来放大图象或者放大衍射模式。
