查询词典 keels

This paper describes a quasi-linearization method for computing the anti-rolling behaviour of ships for the condition of the fin s saturation. In the evaluation of the lift of the fin s the interaction effects between the fin s and bilge keels, and between the fin$$...

本文给出减摇鳍装置工作在鳍角超过饱和点情况下的横摇性能计算方法，并分析了两艘装减摇鳍的船在波浪中的试验结果同理论计算结果的对比，通过理论与实际的比较说明这一方法在选择减摇鳍尺寸以及本装置在船上的布置将是有意义的，并可用来预报装减摇鳍的船舶在不规则海浪中的横摇运动性能。

Spikelets 1–1.2 mm, florets 2; glumes boat-shaped, keeled, scabrous on vein, ca. 1 mm; lower glume subacute; upper glume truncate, awn 0.3–0.5 mm; lemma of fertile floret broadly boat-shaped, ca. 1.2 mm, leathery, pilose along keel and incurving margins; palea obovate, narrower than lemma, keels scabrous; upper lemma much reduced, cuneate, lying within concave back of palea of fertile floret.

小穗1-1.2毫米，小花2；颖片舟状，龙骨状，粗糙的在脉上，约1毫米；更低的颖片近尖；上面颖片截形，芒0.3-0.5毫米；宽舟状的肥沃的小花的外稃，大约1.2毫米，沿着龙骨和incurving 边似皮革，具柔毛；倒卵形，狭窄比外稃，粗糙的龙骨的内稃；上面外稃非常退化，楔形，躺在内凹在内稃的能育小花后面。

Spikelets all alike, slightly laterally compressed, with (1 or)2 to several florets, lower florets bisexual, the upper progressively reduced, disarticulating above glumes but not usually between florets; glumes persistent, membranous, usually enclosing the florets, obviously 1- to many-veined, entire; lemmas broad, rounded on back, 9–11-veined, veins extended into 5–19 awns, sometimes alternating with hyaline lobes; palea broad, subequaling lemma body, keels ciliate.

小穗全部一样，稍侧面压扁，通常，颖片宿存，膜质包围，明显1-在很多脉，全缘；宽，圆形的外稃在背面上，9-11－脉，脉延长进芒，有时互生具透明裂片；内稃宽阔的部分，近相等外稃主体部份，龙骨纤毛。

Spikelets laterally compressed, floret 1, rachilla extension absent; glumes absent; lemma ovate, hyaline, 1-veined, keeled, apex extended into a subulate cusplike awn; palea variable in size, frequently about 2/3 lemma length, broad, 2-toothed, keels extended into mucros.

小穗侧面压扁，小花1，小穗轴扩展无；颖片无；卵形，透明的外稃，1脉，翻转，顶延长成为一钻形的cusplike芒；内稃大小易变，经常大约2/3外稃长度，宽，2齿状，龙骨延伸进短尖头。

The results of the investigation provide a better understanding of the effects of side hull transverse position and bilge keels fitted on each side hull on trimaran roll motion , and some seakeeping characteristics are concluded .

迎浪航行是船舶航行时经常选取的航态，在这种航态下影响船舶作业的主要因素是船的纵摇，垂荡，垂向加速度，甲板上浪及砰击等，且这些方面难以通过减摇措施得到改善，因此这些要素是评价船舶运动性能的重要条件。

A further evolution of the HP Inflatable concept, HP-V floors dispense with sausage-shaped inflatable keels.

另一个变革是HP-V底板取代了原先香肠状的充气龙骨。

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。
