Three-dimensional reconstruction is realized by three-dimensional morphological characteristic of cucumber leaf ,cubic Bezier curve of leafstalk,pentagon leafstalk section,jointing quadrangle leafstalk surface,leafstalk shags built by random and joint sequential C0 cubic NURBS surface in cucumber.

根据黄瓜叶的三维形态特征，利用3次Bezier曲线描述黄瓜叶柄曲线，采用五边形作为叶柄截面，用四边形面片进行叶柄表面拼接，并用随机方法生成叶柄的粗毛；利用C0连续的3次NURBS曲面拼接生成了黄瓜叶片曲面，实现了黄瓜叶的三维重建。

The trefoil is known as the simplest nontrivial molecular knot. The C30 carbyne trefoil knot studied is intertwined by the sp hybridized15 chain, which is topologically chiral and belongs to D3 point-group of symmetry.

三叶结分子是最简单的非平凡纽结分子，C30卡宾三叶结分子是由一条闭合的l5 sp杂化碳链组成的，是具有D3对称性的拓扑手性分子。

The results showed that the crude protein content of the Akebia trifoliata seed was 34.39%, and the crude oil content was 31.37%.

主要分析了三叶木通籽的成分，并对所制取的三叶木通籽油进行了理化指标分析，同时测定了浸出粕的水溶性蛋白含量。

The difference of the elevation in altitude and latitude bring about the difference of the temperature and light duration, and the integrated effect by heat and humidity was important to the geographical variation of the traits in stem growth of Akebia.

结果表明：三叶木通地理变异的基本模式是以海拔垂直梯度变异为主，纬向渐变为辅；海拔及纬度差异产生了温度和光照差异，水热因子的综合选择作用是三叶木通茎藤生长性状地理变异的重要原因，其中温度和光照是主导因子。

The tolerance to glyphosate of Zong 31 and weeds in the 3-leaf period indicated that it was belter to prevente and cure weeds when the glyphosate concentration was 1.2g/l,which was nearly the lethal concentration of Zong 31 in the 3-leaf period.

草甘膦在玉米三叶一心时对玉米和杂草的喷施效果表明，1.2g/l的浓度时对杂草的防治效果良好，对玉米接近致死浓度，所以确定筛选时期选择在玉米三叶一心时期，浓度为1.2g/l。

The Fabaceae have a worldwide distribution and many are of economic importance, including peas, beans, lentils, and peanuts. Others are used for forage, e.g. clovers and Lucerne. There are also ornamental species such as lupins.

Fabaceae 具广泛的分布，并且许多具有重要的经济价值，如豌豆（豌豆 Pisum sativum ）、菜豆(菜豆属 Phaselous 和蚕豆属 Vicia)、小扁豆(兵豆属 Lens culinaris)以及花生(花生属 Arachis byopqea)，其余的用作牲畜饲料，如三叶草（三叶草属 Trifolium ）和紫花苜蓿(苜蓿属 Medicagosation)，还有一些是仅供观赏之用的，如羽扇豆(羽扇豆属 Lupinus)。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
