肉眼

Ground penetrating radar have so many advantage, therefore applied very extensive. But now it still exist some proportion to waiting for improvement, for example, distinguishing the GPR diagram primar ily stays in the foundation of the artificial naked eye distinguish and handcraft identify. Therefore it is beneficial to us to understand the electromagnetic wave spreading regulation, and scoop out much more useful information from the GPR wave inside, through forward simulate the familiar penetrating object in physical.

地质雷达具有如此多的优点，故应用十分广泛；但是目前地质雷达亦还有待改进之处，如雷达图像的识别主要还停留在人工的肉眼和手工的基础上；所以对常见探测对象的物理正演模拟，有助于我们了解电磁波的传播规律，挖掘雷达波中更多有用信息。

Results: The cultured chondrocytes were polygonal cells. There were many rough endoplasmic reticula and mitochondria in cytoplasm, and a lot of secretory vesicles under cell membrane and in the cytoplasm. When cultured for 10 days, some small and white nodules were formed on the bottom of the culture dished, and volcanic-mouth-like structures were formed when cultured for 20 days. Both these nodules and structures contained GAG-positive substances were demonstrated by safranine-O staining.

结果：体外培养的软骨细胞为多角形，透射电镜下见胞浆内有丰富的粗面内质网系统及线粒体，胞膜下及胞浆中有较多分泌泡；连续培养10天时，培养瓶底部出现肉眼可见的白色结节，蕃红-O染色显示白色结节含大量氨基葡聚糖阳性物质，20天时形成火山口样结构，也被蕃红-O染成深红色。

Tuberculous lesions were identified in 27 cattle (47.4%; n = 57) with the evidence on gross and/or microscopic examination in 1 or more sites. The most frequently affected site was retropharyngeal lymph node, followed by mediastinal lymph node, hilar lymph node, and mesenteric lymph node.

结果显示，所收集的结核菌素检测阳性牛中，有 27 头（47.4%； n = 57）在肉眼或／及显微检查下发现有结核样病灶，其中最常出现病变的位置为咽背淋巴结，其次依序为纵膈淋巴结、肺门淋巴结和肠系膜淋巴结。

Light microscopic evaluationshowed that PMMA was in loose contact with the bone trabecula,PMMA could not be resorbed,and new bone could not be found.

肉眼观察：PMMA与松质骨界限清晰，一个椎体取材时交界面出现破碎和脱落现象；而CPC和rhBMP-2/CPC与椎体内松质骨界限不清，互相融合生长。

The surface of the post-core in the control groups were all oxygenized while those in the gilding groups had been oxygenized only near the margins of the cores and the upper 1/3 part of the post with uncontinuous and relatively thin layers.

肉眼观察：对照组桩核表面全部覆盖较厚黑色氧化层；镀金组近核边缘处和核下方桩颈1/3处有较薄散在的氧化层。
