The concept of the reverse gcometry CT has been borrowed and extended. The fully reconstruction conditions and the relevant reconstruction algorithm in view of parallel and fan beam projection are given too.

3提出了倒置结构断层CT的概念，并就平行束和扇形束两种情形，给出了倒置结构断层CT的完全性条件、成象结构的各参数之间必须满足的条件及重建算法。

It is interesting to see comparative diagrams of Amos and Inverted Amos antenna each with seven dipoles.

如果你需要一个比阿摩司天线更窄的水平辐射角的天线，反转阿摩司天线作为一个扇形覆盖面的天线是非常有用的。

Here, a brilliant red sea fan coral spreads behind a golden damselfish in waters off Fiji's Namenalala Island.

这里，灿烂悠久的红海扇形珊瑚扩展背后的一个黄金damselfish在离开水域斐济的 namenalala岛屿。

Read this if you want to have very advanced understanding of the fan movement, or latin dance in general.

如果你想对拉丁舞中的扇形动作或者总体上的拉丁舞有个非常高级的理解，那请看下本帖。

The marginal division was a flat fan-shaped structure with a volume of (0.48±0.02) mm3, a maximum rostral-caudate axis of 1.6 mm, a maximum dorsal-ventral axis of 2.158 mm, and a widest axis (the diameter at lateral-medial coronal brain section) of 0.17 mm. The marginal division also moved progressively externally from the rostral section to the caudate section, but its scope was larger than that of others. The whole marginal division changed evenly from the rostral section to the caudate one. Its flat structure widened progressively and its dorsal-ventral diameter narrowed gradually and became plate-shaped.

边缘区呈现一个片状扇形结构，体积为(0.48±0.02) mm3，最大嘴尾径为1.6 mm，最大背腹径为2.158 mm，最大内外径为0.17 mm；同尾壳核和苍白球一样从嘴侧到尾侧随着脑平面的增宽边缘区亦逐渐向外侧移位，其移位的幅度亦明显大于脑平面增宽的幅度；整个边缘区从嘴侧到尾侧呈均匀变化，其片状逐渐变宽，长度逐渐变小，从而形成一个盘状结构。

小的，个别的珊瑚水螅体融合在一起随着时间的推移造成这些令人印象深刻的扇形殖民地，能生长几英尺高。

Because the resistance transmitter is built in the tooth gear, when deflexion occurs on the axle of the segment gear, the rocking arm of the resistance transmitter deflects accordingly.

由于电阻发送器系设置在齿轮传动机构上，因此当齿轮传动机构中的扇形齿轮轴产生偏转时，电阻发送器的转臂也相应的地偏转。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
