视重量

In order to meet the requirements of high space resolution, high spectral resolution, high time resolution, small volume and light weight for the remote sensing of pilotless planes, the off-axis three-mirror anastigmatic optical system is adopted.

针对无人机遥感要求高空间分辨率、高光谱分辨率和高时间分辨率且体积小、重量轻，采用离轴三反消像散光学系统满足其大视场轻量化设计要求。

Even as a wide-angle beyond 60 degs.

尽管视场很大（表观视场在60度以上），机械强度也合适，这类镜子的重量也不会超过800克。

Contrasting foreign digital aerial cameras, the conclusion was taken that SWDC was superior in the field of elevation accuracy, ration between volume and weight, the angleof field-of-view, the field corner pixel cents and the Ration between baseline and height.

本文首先阐述了SWDC数码航空相机设计方案、主要技术指标及其改进的关键技术，通过与国外数码航空相机的对比，得出SWDC在视场角、基高比、高程精度、体积重量比等关键指标上都优于国外数码航空相机的结论。

This follows Newbury and Britton's 1973 method for using up weight from exhausted ballots under STV.

在此之前，纽伯里和布里顿的1973年的方法使用了重量从下用尽票数超视。

A method for the preparation of microcellular elastomeric polyurethane foams from a reaction mixture comprising a polyisocyanate component containing at least 85% by weight of 4,4'-diphenylmethane diisocyanate or a variant thereof, a polyol composition comprising at least one polyoxyalkylene polyol having an average nominal hydroxyl functionality of from 2 to 6, an average hydroxyl equivalent weight of at least 1300 and an average oxyethylene content of between 50 and 85% by weight, water, a chain extender having an average hydroxyl equivalent weight of from 15 to 250 and optionally a crosslinking agent, the hardblock-content being more than 45% by weight.

本发明是有关一种制备微孔弹性聚氨基甲酸酯泡沫体的方法，其反应混合物包括：一种含至少85重量％的4，4′－二苯甲烷二异氰酸酯或其变体的聚异氰酸酯组分，一种多元醇组合物，其包含至少一种平均标称羟基官能度从2至6、平均羟基当量至少1300且平均氧乙烯含量介于50至85重量％之间的聚氧亚烷基多元醇，水，一种平均羟基当量为15至250之增链剂，以及视需要使用的交联剂，该硬性嵌段－含量（hardblock-content）大于45重量％。

We had designed and produced the por-table ophthalmic operating microscope whichis compact in constraction, light in weight(19kg only) and convenient in carrying, excel-lent in optical quality, strong in stereognosis,wide in visual fie1d, low in price, and rotable in360 round, hence this kind of operating micro-scope is benefit in popularization ofophthalmic microsurgery and increase of therate of success of ocular operation in basic-level hospitals.

立体感；成功率；光学质量；眼科；人工晶体；青光眼手术；轻便式；手术显微镜；显微手术；放射状切开；我们设计并生产了轻便式眼科手术显微镜，这种显微镜体积小，重量轻(仅19kg)，一人即可携带，而且光学质量高，立体感强，视场大，可做360°范围旋转，价格低廉。这样可以尽快使显微手术在国内普及提高手术成功率，使数以万计的眼病患者都能在当地得到良好的治疗。

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）。

With its liquid-cooled, four-stroke Rotax 200 engine, lightweight SST frame, front and rear hydraulic disc brakes and spring pre-load adjusters, this ATV is ready to take on the roughest trails.

其液体冷却，四冲程rotax 200发动机，重量轻SST的框架，前方和后方，液压盘式制动器和弹簧预加载调节，这是亚视准备采取对粗糙的路径。

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.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. 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。
