Although the production of relatively small achromatic and apochromatic refractor telescopes of up to 15cm, and catadioptic systems of up to 18cm, all with a variety of accessories at Jena would continue until 1994 when it was realized that Zeiss could not compete in the world market; the Zeiss "APQ" refractor telescopes optics were among the finest in the world but the inability to Zeiss to adapt these products promptly to the realities of a free marketplace assured their demise.
虽然耶拿厂可以生产相对小点口径的消色差和复消色差折射望远镜（口径最大可达15cm），还有口径最大可达18cm的反射折射望远镜系统，而且产品规格类型丰富，但蔡司在1994年还是意识到，不能在此类产品的世界市场上继续竞争了；蔡司的"APQ"系列折射望远镜产品确实属于世界顶级产品之列，但蔡司不具备在自由市场经济环境下，迅速调整改进此类产品的能力，所以决定此类产品停产。

Manufacture of big aperture lightweight paraboloidal mirror is one of the key techniques for the research of the Cassegrain optical system.
研制某卡塞格林光学系统的关键技术之一是通光口径超过1000mm的轻质抛物面主反射镜。该反射镜相对口径为1/2，减重率为65%，是目前国内最大口径的轻质非球面反射镜。

It is only equipped with a caliber 25 mm M242 cannon, 7.62 mm coaxial machine gun 1, 7.62 mm caliber fixed machine-gun turret at the top of a difficult pose a threat to armored targets on the battlefield, so the "Kodiak Bear" armored vehicles fire difficult to adapt to the needs of the battlefield.
它只装备有口径25毫米的M242机关炮、7.62毫米口径共轴机枪一挺、7.62毫米口径顶部炮塔固定机枪一挺，难以对战场装甲目标构成威胁，因此，"科迪亚克熊"装甲车的火力难以适应战场的需要。

Reflector telescope relative a larger diameter can be done, the main focus of the relative telescope diameter is about 15-125, even greater, Wang DC, inter Newton Telescope, the tube is longer than the system is much shorter focal length, coupled with the main mirror is only one apparent need for processing, which greatly reduces cost and manufacturing difficulties, there is currently greater than 134 meters diameter optical telescopes are all reflecting telescope.
反射望远镜的相对口径可以做得较大，主焦点式反射望远镜的相对口径约为15—125，甚至更大，而且除牛顿望DC远镜外，镜筒的长度比系统的焦距要短得多，加上主镜只有一个表面需要加工，这就大大降低了造价和制造的困难，因此目前口径大于134米的光学望远镜全部是反射望远镜。

Branch diameter distributions changed from an abundance of small-diameter branches in the upper-crown, and in the middle-crown, composed with differential branch diameter, but only a few large-diameter branches in the lower-crown. Branch volume generally increased from upper- to lower-crown, and reached a maximum around the crown base. Branch density decreased from upper- to lower-crown.
枝条口径分布，从树冠上层多数的小径枝条至树冠中层转变为含不同口径枝条且变异较大，在树冠下层仅由少数大口径枝条组成；枝条体积则由树冠上层向下层增加，至树冠基部达最大值；而枝条密度则从树冠上层向下层逐渐递减。

aperture：口径
望远镜的能力便完全依赖于这些透镜的直径,这便叫做望远镜的"口径"(aperture). 口径的大小不等,可以从家用小望远镜的10厘米左右,一直到叶凯士天文台(YerkesObservatory)大型折射望远镜的1.02米. 三百年前的天文学家都以为绝无办法避免透镜的色散作用.

caliber：口径
人们通常说一把枪(线膛枪,以下皆同)的口径(Caliber)是多少多少,比如说7.62毫米、5.56毫米等等,其实正确的概念来讲这些数字指的是枪所用弹药的口径. 道理很简单,任何一把枪都是围绕已有的弹药来研制出来的,即先有弹后有枪,
