A CAT scanner, however, uses a beam of X-rays to give a cross-sectional view of a specific part of the body.

然而，CAT扫描仪却可以利用一束X射线照出一幅体内指定部位的断面图。

Wolfe suggests that examples of evidence for this may possibly be seen in the Wandjina tradition and in a faded cave painting in southern Australian, which depicts a circular, striated image with what may be "rays" coming out of one side.

沃尔夫认为，实例证明这可能是出现在Wandjina传统和消失在洞穴绘画在澳大利亚南部，描述一个圆形，条纹图像可能是"射线"出来的一个方面。

Now, the Rays' center field feels like he is back on track.

现在，这位光芒的中外野手觉得自己已经回到正常轨道了。

But in the repeated curve of her thigh and calf he saw shapes like sea shells, with the luminescence and faint muscular rays of the great chambered nautilus.

在大腿小腿不断抓拍到的曲线让他想到了海贝的形状，腿部肌肉明暗交接的光线就像大鹦鹉螺。

The number of characteristic X-rays of a certain element is proportional to its concentration, providing the basis for quantitative analysis.

每个元素特征的X射线的数量正比于它的浓度，为定量分析提供了基础。

Cobia are primarily sought by sight casting small Chartreuse jigs to migrating fish, or to fish following turtles or manta rays.

因数主要要求见铸造小黄绿色的迁移夹具捕鱼，或鱼后海龟或 manta 照射。

The pupae were exposed to 9 krad 60Co-γ rays for two days before emergence.The adults were dissected and many mature sperms could be seen in the male flies.There were no significant difference in the form,number and vigor of sperm between irradiatid and unirradiated male flies,but there were some abnormal ultrastructurail changes in the sperm of irradiated male flies such as the appearence of vacuoles in nutrient cells,disarrangement of sperms,variation of the number of chondriosome derivates,axonemes ction of formation and abnormal cell division of sperm cells.

用9krad辐照羽化前2天的蛹，成虫羽化后解剖观察，雄虫已有大量成熟精子，精子形态、数量和活力与未经辐照处理的雄虫无显著差异，但其超微结构则发生了某些异常变化，如营养细胞出现空泡、精子排列零乱、线粒体衍生体和轴丝增多或减少、构型被破坏、精子细胞分裂异常等。

By analytic geometry method and solving quadratic equation,a computer simulation algorithm of digital projection under arbitrary scanning locus was proposed.The algorithm is based on the rules of attenuation of monochromatic X-rays.Through mathematical modeling and computer simulation,digital projections of ellipsoid and cylinder in circular and helix scanning modes are exemplified respectively,which are proved to be correct by FDK and PI-line reconstruction algorithms.

介绍了一种利用解析几何和求解二次方程仿真任意扫描轨迹下的锥束射线投影数据算法，该方法基于单色射线贯穿物体的衰减理论，通过数学建模与计算机仿真，给出了椭球、圆柱两种典型模型分别在单圆、螺旋线扫描轨迹下的投影数据仿真结果，并利用FDK和PI线重建算法进行验证，证明了该种数值仿真方法的正确性。

After explaining total design of automated test system for microcircuit , the thesis introduces GPIB standard .

文章在说明了微电路模块自动测试系统的总体设计后，对GPIB标准进行了介绍。

He interceded in my behalf.

他替我说情。
