They sit cross legged, in concentric circles... like growth rings in a tree.(他們交叉著腿坐成一個個同心圓…就像樹上的年輪。)

Bone growth in reptiles is periodic in nature, producing a series of concentric rings in the bone, not unlike the growth rings of a tree.(爬行動物的骨骼生長在本質上是周期性的，在骨頭上產生一系列的同心圓，就像樹木的年輪一樣。)

Dr Yabe's trick is to use relatively small Fresnel lenses-transparent and relatively thin planar lenses made up of concentric rings of prisms.(Yabe博士的訣竅是使用比較小的菲涅爾透鏡——棱鏡同心環構成的透明較薄的平面透鏡。)

Think of this process as a series of concentric circles beginning with our own individual, spiritual awareness as the innermost circle.(可以將這一過程看做一組同心圓，最內層即是每個人獨特的精神認知。)

The cultures are represented by concentric rings, and the emotions are represented by slices of the circle.(同心圓代表不同的文化，而小方片代表了不同的情緒。)

His verdict, arrived at after he scoured over 10, 000 points on the microwave maps, is that Dr Penrose's concentric circles are real.(在去除微波地圖上面的超過10000個點之后，他得出彭羅斯博士的同心圓是真實存在的結論。)

Each half-circle is offset by computed x and y coordinates in order to ensure that they are concentric.(根據算出的x和y坐標，各半圓將偏移以保證同心。)

The Earth's axis points toward Polaris, the North Star, near the center of the concentric trails.(地軸指向北極星，在這一圈同心圓中心附近。)

Their home was made up of concentric islands separated by wide moats and linked by a canal that penetrated to the center.(他們的家園由同心島嶼構成，用寬闊的護城河隔開，并通過一條貫穿至中心的運河相互聯系。)

Women tended to enter in one corner and search in concentric circles or lines.(而女人則更傾向于從一個角落開始，然后以此為圓心向外擴張，或者直線向前。)
