(61) The many indefinite exists in the design parameters and influence factors of the working stress and allowable stress of the K - H three - ring planetary reductor.

(62) The whole field of planetary gear transmission is dealt - with.

(63) Basing a global civilisation on the empowerment of a few thousand and the impoverishment of six billion is like lodging depth charges in the planetary core.

(64) And it is these that are helping scientists to resolve the outstanding mysteries of the complex shapes and symmetries of planetary nebula.

(65) Decelerating machine planetary transmission structure the characteristics of high transmission efficiency, small volume and light weight.

(66) Planetary reducer motor with small size, light weight, wide range of reduction ratio, high transmission power, smooth running, compact structure, high bearing capacity.

(67) Because the craft is excluded from the planetary gravity, the crafts are capable of fantastic acceleration and sharp turns in high speed without the crew inside the craft feeling any G-force effects.

(68) Mars's rapid formation might help explain why it is so small –the runt of the planetary litter among inner worlds in our solar system –say the study's co-authors.

(69) The finding suggests one commonly accepted model of planetary formation, where icy chunks glom into a core, wouldn't work here.

(70) Secondly , kinematics and statics of the planetary intermittent mechanism are studied.

(71) Only 9 other red dwarfs are known to have planetary companions, and these were all discovered through the radial velocity technique.

(72) Gear shape is calculated and interference of planetary gear dedendum and internal gear addendum is avoided.

(73) Planetary geologists formerly believed that any impact ejecta with speeds exceeding the Martian escape velocity would almost certainly be vaporized or at least completely melted.

(74) The planetary circular tooth chain retarder is a new type of planetary transmission apparatus.

(75) Geochronology is the science of measuring ages, rates, and histories of geologic or planetary materials, and using these insights to understand processes and phenomena in earth and planetary science.

(76) A mathematical model of planetary mechanism dynamic coupling device was built after analyzing the characteristics of motion to planetary mechanism.

(77) The Cat's Eye Nebula (NGC 6543) is a planetary nebula in the constellation of Draco.

(78) He received his Ph. D. in planetary science from the California Institute of Technology in 1985. Lunine is the author of Earth: Evolution of a Habitable World (Cambridge University Press, 1999).

(79) She is a member of the UA-based Cassini VIMS team(sentencedict.com), headed by Professor Robert Brown of UA's Lunar and Planetary Lab.

(80) Maybe it was a onetime moonlet of Iapetus, explained Kevin Walsh of the Southwest Research Institute in Boulder, Colorado, at a recent planetary science meeting in France.

(81) The electrogenerativeleaching of galena mechanical activated in planetary centrifugal mill are studied.

(82) Planetary nebulae are a type of isolated gaseous nebulae possessing a fair degree of bilateral symmetry.

(83) On the basis of analysis, the probable way for improving the dynamic performance of three-ring transmission by increasing the planetary bearing rigidity of the system was put forward.

(84) There is the story of how he informed Halley of one of his most fundamental discoveries of planetary motion.

(85) Conversely, astrometry works best when a planetary system is "face-on" when seen from Earth,[Sentencedict.com] because then the star's movements in the orbital plane are most pronounced.

(86) The planetary alignment could cause you to see someone whom you badly want to believe in through rose-tinted spectacles.

(87) When the planetary migration occurs under the tidally interaction of a planet and a disk of gas or a planetesimal, the orbital parameters, especially, semi-major axis, of this planet will be altered.

(88) Kepler's three laws of planetary motion -- formed in the early 17th century -- describe how planets orbit the sun.

(89) And we're just now announcing the discovery of the fifth planet, the first planetary system with five full planets orbiting a sunlike star." Our solar system has eight planets.

(90) The bike chain drives a sun gear on the rear axle, which transmits power to planetary gears situated around it.
