查询词典 oculars

Of course, one has to recall that the Swarovski's field is so narrow that critical areas of the field were excluded from the very beginning, and it is likely that the optical design did not require anything more than ordinary 3-lens-element reverse Kellner oculars.

当然，联想起Swarovski的视场是如此的狭窄，视场的临界面积从一开始就被排除掉了，并且看起来它的设计只需要3片普通镜片的 Kellner目镜。

Military glasses have got a reticle inside one of their oculars, and this glass plate usually serves as an extra source of reflections.

军用镜子在一只目镜内有刻度板，这块玻璃板经常是产生倒影的另外源泉。

As can be verified on this list , the first of the 50 mm models, the 7x50, appeared in 1956, followed by the 8x50 and 10x50 in 1957 (the 7x50 B/GA is, with few modifications and with individually focused oculars, still in production).

在这个单子上可看到，第一款50mm镜子，7x50诞生于1956，后面跟着8x50和10x50诞生于1957年（7x50 B/GA，只有很小的改动，目镜独立调焦类型现在仍在生产）。

But wide angle oculars with long focal lengths have large field lenses, which require large prisms to be illuminated to the edges of the field, and this leads to an expensive and bulky instrument.

但宽视野又长焦距的目镜含有广角镜片，这需要大棱镜照亮视场边缘，导致价格昂贵和体积巨大。

Additionally, the Nikon SE is not waterproof, and the Fujinon has got uncomfortable, individually focusing oculars.

它们也没有什么旋升眼罩或者最近对焦距离2米这样的特色。

Since today's trend goes towards low weight and compact binoculars, optical designers have become reluctant to offer wide fields of view which require larger prisms and expensive oculars with additional lens elements but: Check the No.

当前的趋势是低重量更紧凑的镜子，光学设计师不愿意提供大视场，这需要需要更大棱镜和更贵的需要增加镜片个数的目镜（但，核对 collected wisdoms 的第九条）。

Further features include spectacle-friendly oculars, twist-up eye-cups and a central focuser.

更多的特点包括能适合眼镜的的目镜，旋升眼罩，中心调焦。

Finally, oculars with narrow apparent fields of view can be of simpler construction than wide angle binoculars (e.g. 3 lens element reverse Kellner instead of 5 lens element Erfle), are therefore cheaper, provide a better light transmission and are less prone to ghost images, because they contain less air-to-glass surfaces.

最后，小视场目镜也可以比广角望远镜结构上更简单（如Kellner的3片式代替Erfle的5片式），也因此更便宜，提供了更好的透光性，因为减少了玻璃表面，也减少了产生鬼影可能。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides.

The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
