Results The main imaging of adult polycystic kidney disease signs: abdominal plain film (45 cases) showed renal shadow was lobulated increase; cystic wall calcification (14 cases); polycystic kidney disease and renal milk of calcium (8 cases); pelvis angiography (61 cases), the performance of the renal pelvis, renal calices separated, distorted, elongated; retroperitoneal inflatable angiography (6 cases): Performance increases of renal kidney shadow Shadow and the relationship between the neighboring organs, its boundaries clear and identified; CT scan (30 cases): the performance of the majority of the size of the renal low-density areas, ranging from thin-walled circular; B-mode ultrasonography (47 cases) showed a circular echo-free renal multiple classes of liquid dark area .

结果 成人多囊肾的主要影像学征象：腹部平片(45 例)显示肾影呈分叶状增大；囊壁钙化(14例)；多囊肾合并肾钙乳(8例)；肾盂造影(61例)，表现为肾盂、肾盏相互分离、变形、拉长；腹膜后充气造影(6例)：表现为肾影增大肾影与邻近器官之间的关系，其界限清晰可辨；CT扫描(30例)：表现为肾内多数大小不等的薄壁圆形低密度区；B型超声(47例)表现为肾内多个类圆形无回声的液性暗区。结论影像学检查有助于提高多囊肾的诊断的准确性。

Water stress could largely affected on cell structure of leaf, with enhanced degree of water stress, the karyon amount decreased, and the nucleolus reduced, distorted or degraded.

水分胁迫对叶细胞结构也有很大影响，随着水分胁迫程度的增强，细胞核数量减少，核缩小、变形或降解，解除胁迫以后也很难恢复。

METHODS: Three patients who reported metamorphopsia but showed no changes in the retina in conventional fundus photographs were examined. High-resolution retinal images were obtained with the AO fundus camera and by FD OCT. The images were compared with the findings obtained by standard clinical tests, including Amsler charts and fluorescein angiography.

对报告有视物变形但经传统眼底照相未发现视网膜变化的3例患者进行检查，使用自适应光学眼底照相和傅立叶域光学相干成像获得高频视网膜图像，将所获得的图像和标准临床检查结果对比，这些标准临床检查包括Amsler方格和荧光血管造影。

Types of microstructures are microfoliation, silt inclusion, microorientation and microflexure.

微构造类型有：微叶理、粉沙团块、微旋转和微褶皱变形构造。

The disorderis char-acterized by necrosed upper leaves and by leaf curling,distortion or leaf tip burn Fig.

这种疾病的典型症状是上层叶片出现扭曲、变形或坏死在世界各地种植百合的温室都会经常发现叶烧病的踪迹。

We focus on resolving the following problems in FTP, that is how to guarantee the measurement accuracy of FTP when the connect line between the exit pupil of the projecting lens and that of the entrance pupil of the imaging lens is not parallel to the reference, or the two pupils are not coplanar, or neither the connect line parallel to the reference nor the two pupils coplanar.

推导出了适用范围更广泛的变形条纹描述公式和相位计算方法以及相位—高度映射算法。对于传统的傅里叶变换轮廓术测量系统而言，由于要求投影仪出瞳与摄像机入瞳连线与参考面平行，而且要求投影仪光轴与摄像机光轴共面，所以它可以被看作是本文所提出系统结构在该种情况下的一种特例。
