  2. Gassendi estimated mercury ' s apparent diameter to be about 20 arc seconds ? that is, about 1 / 180 of a degree ? which was in itself a considerable scientific advance

    賈山迪估計水星的視直徑大約是20角秒(約是1度的1 / 180 ) ,這本身就是一大科學進展。
  3. By compounding caco3 with pp, the effect of caco3 content, diameter and shape on the crystallization, dispersion morphology and properties of pp / caco3 composites was investigated. the results showed that addition of caco3 into pp decreased the apparent crystal size in perpendicular direction to the ( 110 ), ( 040 ) and ( 130 ) crystallographic planes of ppa crystal, and with similar uniform dispersion of caco3, the dominant factor influencing toughness is the diameter of caco3 particles, but not the decrease of pp crystal size. the toughening effectiveness of nano caco3 is obviously better than that of micron caco3

    將caco _ 3與pp進行填充復合,研究了caco _ 3含量、粒徑及形狀對體系的結晶,分散形態及性能的影響,發現碳酸鈣的加入使聚丙烯晶型垂直於( 110 ) 、 ( 040 )和( 130 )晶面的表觀晶體尺寸減小,揭示了在分散均勻的情況下,影響材料韌性的主導因素不是晶粒尺寸的減小,而是碳酸鈣的粒徑,納米張玲:彈性體及無機剛性粒子增韌增強聚丙烯復合材料的研究碳酸鈣的增韌效果明顯優于微米碳酸鈣。
  4. A " saddle " shape appears in the curve of relationship between smd ( sauter mean diameter ) and charging voltage, the droplets " size distribution fluctuates with the change of charging voltage. the influence of electric field on flow field is apparent. the distribution of velocity and turbulent energy, structure and size of vortex appear different changes with the increase of voltage of charging

    索太爾粒徑隨電壓的變化曲線中出現「馬鞍」現象,粒徑的分佈情況隨電壓的升高出現波動性變化;電場對流場的作用明顯,速度與湍能的分佈及渦的結構等流場特性隨電場的改變均有不同規律的變化。
