Their names became attached to the days of the week: Sunday (dies solis,"Sun's day"), Monday (dies lunae,"Moon's day"), and Saturday (dies Saturni,"Saturn's day") retain their names derived directly from the Roman culture, and Tuesday ("Tiw's day"), Wednesday ("Woden's day"), Thursday ("Thor's day"), and Friday ("Frigg's day") are derived from the Germanic equivalents of Mars, Mercury, Jupiter, and Venus, respectively.

他们的名字已成为附一周的天数：周日（模具Solis表示，"太阳节"），周一（模具lunae ，"月亮节"），以及周六（模具saturni ，"土星上的一天"）保留自己的名字直接源自罗马的文化，以及周二，周三（" woden的一天"），周四，以及周五，都源自于日耳曼等值的火星，水星，木星，和金星。

Light guide plate molding technology is a optic dot transfer method by molding. Melt resin is injected into mold cavity, where optic dots are carved on to cavity surface. Then melt resin is transfered to LGP by keeping pressure, cooling and ejecting. Molding LGP have optic dots as same as optic dot design of mold stamper. LGP accidented optic dots are relative with mold optic dots.

导光板注塑成型技术是一种通过光学网点转移的方法成型导光板的技术，即将融熔树脂注入带光学网点的模具型腔，经过保压、冷却后脱模得到导光板，注塑成型得到的导光板具有模具型腔所赋予的光学网点，这些网点的凹凸性和模具型腔网点的凹凸性互补。
