Original height 146.5 meters, because the year long time makes decent, the peak flakes 10 meters, present height 136.5 meters; Foundation each length of side more than 230 rice, triangle surface ascent 52 degrees, tower floor space 52,900 square meters; The tower body builds by 2,300,000 stones, each stone average weight 2.5 tons, some amount to several dozens tons again; Some scholars estimated, if ships pyramid's stone material with the train, must use 600,000 freight cars approximately; If chisels garrulously these stones, the shop becomes a foot wide path, may circle an Earth week approximately.

原高146.5米，因年久风化，顶端剥落10米，现高136.5米；底座每边长230多米，三角面斜度52度，塔底面积5.29万平方米；塔身由230万块石头砌成，每块石头平均重2.5吨，有的重达几十吨；有学者估计，如果用火车装运金字塔的石料，大约要用60万节车皮；如果把这些石头凿碎，铺成一条一尺宽的道路，大约可以绕地球一周。

Cassini came within about 5,900 miles of Mimas and these images were obtained with Cassini's narrow-angle camera on that day at a distance of approximately 10,000 miles from Mimas.

NASA/JPL/Space Science Institute 在这个2010年2月13日飞越，卡西尼号在大约5，900米玛斯来到英里和获得这些图像与卡西尼号上的窄角相机距离土卫一上的10000天在大约距离。

By 1937 Zeiss listed about 20 high quality monocular, binocular and stereo microscope configurations in their literature. And they also marketed a wide selection of optional attachments and illuminators including at least 33 objectives of from 2X to 120X, and about 20 eyepieces of Huygens, Orthoscopic, and Compensating designs of from 3X to 30X.

1937年，蔡司文献上就已经有了大约20种高品质单目望远镜、双目望远镜和立体显微镜，并且还有很多可选的光学配件，说明书中列出了至少33种2倍到120倍物镜（其中包括6种为使用萤石型），至少大约20种3倍到30倍的惠更斯型，无畸变型(直线型Orthoscopic)，和补偿型目镜。

Combined with the vacuum harvesting device, it could automatically concentrate 350-liter of the rotifer culture with a density of about 250 rotifers/ml to about 15,000 rotifers/ml in less than 13 minutes.

结合真空收获装置与滚筒过滤机而成的自动化系统可以在13分钟内将350公升的轮虫由密度大约250/ml浓缩到大约15，000/ml。

For example, the eccentricity changes over time cycles of about 100,000 and 400,000 years, with the value ranging from less than 0.01 up to 0.05.[15][16] This is equivalent to a change of the semiminor axis of the planet's orbit from 99.95% of the semimajor axis to 99.88%, respectively.

例如，离心率大约在小于0.01至0.05之间变动，变动周期大约是10万年至40万年，这相当于行星运行轨道的短半轴相对于长半轴的比例在99.55%与99.88%之间发生变动。
