Erect forest tree of Cuba and Jamaica having variably hairy leaves and orange-yellow or orange-red flowers; yields a moderately dense timber for cabinetwork and gunstocks.

古巴和牙买加的竖直的森林树种，有易变的多毛的树叶和橘黄色或橘红色的花，为细木工和枪托产生一种中等密度的木材。

Actually at ordinary times pose and movement should ask again only strict oneself a bit with respect to can thin body, so as dawdler the pose that you want careful him attention!

背部要保持竖直，可以垫个靠垫，手臂打字或看资料要保持90度，这样身体各个部位的肌肉都将得到最大程度的拉伸变长。

Exponential dichotomy describes a kind of hyperbolicity of the system. That is, the state space can be decomposed into a direct sum of two subspaces, which are continuous and invariant. And with the time evolving forward, the system is exponentially attracting in one subspace and exponentially expanding in the other subspace.

指数二分性描述了系统的一种双曲性现象：状态空间可以分解成两个连续不变的子空间的直和，随着时间的正向变化，系统在其中一个子空间上表现出指数压缩行为，而在另一个上面表现出指数扩张行为。

My head become more round which occupies half of my body.

我的头逐渐直起来，而且开始变圆。

Howbeit , he is not sensitive enough to run out in time when the

可是他的体察术还是慢了，等他发现一股颤动变了方向直向他的脚下向冲上

In order to meet the demand of precise measurement and applications, the principle of phase retardation with oblique incident angle is expounded, based on the total-reflection phase transformation theory of the phase retardation. By means of Fresnel rhomb, the variation law of the phase retardation for rhomb-type retarder with the incident angle is analyzed. The result indicates that incident angle has obvious influence over the phase retardation.The phase retardation is sensitive to the incident angle, and also has close correlation to incident position of the incident ray, which is asymmetrical to the incident position of the incident ray.

为满足精确应用和测量的需求，从相位延迟的全反射相变理论出发，阐述了斜入射相位延迟原理，以菲涅耳菱体为例，分析了菱体型相位延迟器相位延迟随其入射角变化的规律性，结果表明：当光线非严格准直时，光的入射角对相位延迟量有明显的影响，延迟量不但对入射角变化敏感，而且还与入射光线的入射方位密切相关，呈不对称形式。

But it always had a rippling wave in it then, and now it seems smooth and straight.""

When a woman decides to use one of these tools, their hair becomes flat and free of curls without damage, because the heat they output is much less damaging than steam and standard flat iron hair straighteners in general.

当一个女人决定使用这些工具，他们的头发变得平坦和自由的卷发而不损坏，因为它们的热量要少得多产出比蒸汽破坏和标准持平铁头发直一般。

According to the summation Fourier series of three kinds of methods, the relationships among the harmonic performance, vertical offsets and modulation index are obtained in the paper.

根据线电压的谐波分量理论表达式，获得了载波之间竖直方向的交叠量、幅值调制度和多电平逆变器谐波性能指标之间的规律。

In the case when the rod is under constant twist and increasing tension force the straight equilibrium can be unstable and transfers to helical equilibrium.

在扭矩不变条件下增加拉力至极限值时，直杆平衡状态失稳转为螺旋杆状态。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
