It contains about 100 clusters in 100 mpc mega parsec , a million parsecs 眾多星系團(tuán)又再組成一個(gè)橫跨1億秒差距包含100個(gè)星系團(tuán)的
Typically , a cluster of galaxies contains 1000 galaxies within a million parsecs . in a larger scale , clusters group together to form 一個(gè)典型的星系團(tuán)大小約一百萬(wàn)秒差距,包含大約1000個(gè)星系。
513km s mpc , ie , for a celestial object 1 , 000 , 000 parsec away from us , its recession rate is 513km 1 parsec 3 . 26 light years 513 km s mpc ,即一個(gè)距離我們一百萬(wàn)秒差距的天體,它的退行速度是每秒513公里一秒差距3 . 26光年。
This is the apparent magnitude of an object at some standard distance from us . this standard distance is chosen to be about 32 light years 10 parsecs , see below 絕對(duì)星等是恒星距離為約32光年或10秒差距請(qǐng)參閱下一節(jié)時(shí)的星等。
First , the improvement in the connection building time and improvement based on hypothesis makes the existing smacs protocol suitable for the wsn . and the paper proves this statement by using the parsec software 通過(guò)仿真軟件ns對(duì)smac協(xié)議的能耗、延遲、流量等參數(shù)進(jìn)行仿真測(cè)試,進(jìn)一步論證了smac協(xié)議的實(shí)用性。
a unit of astronomical length based on the distance from Earth at which stellar parallax is 1 second of arc; equivalent to 3.262 light years 同義詞:secpar
PARSEC is a package designed to perform electronic structure calculations of solids and molecules using density functional theory (DFT). The acronym stands for Pseudopotential Algorithm for Real-Space Electronic Calculations.
