But this molecular model shows how some proteins form loops in DNA when they chemically attach, or bind, at separate sites to the double-helical molecule that carries life's genetic blueprint.

就像槲寄生包绕在柔软的甘蔗蔓藤上，分子模型展示了某些蛋白在DNA 如何形成环状，当它们用化学键贴或者绑在携带生命遗传蓝图的双螺旋DNA分子。

Astronomers have spent many decades trying to measure basic galaxy properties such as age, mass or dustiness that may give us some clues as to how they formed and evolved and what precisely the connection between spiral and elliptical galaxies is.

天文学家花费了几十年试图去估量基本的星系特性，比如年龄，质量或者含尘量，这些可能会给我们关于星系是如何形成和发展的以及椭圆星系和螺旋星系之间的精确联系是怎样的一些线索。

It is very important to deeply study the formation and the dynamics of spiral wave.

因此深入研究螺旋波的形成及其动力学行为具有重要的意义。

It implies that the rotation of earth and basic current are playing an important role in the spiral structure of the Rossby waves.

基本西风气流和地球的旋转，对於Rossby波的螺旋结构的形成是十分重要的。

Elater One of many elongated spirally thickened cells that are formed within the capsule of certain liverworts (e.g. Marchantia and Pellia).

弹丝：在某些苔类孢蒴中所形成的许多加长的螺旋型加厚细胞，。

Unlike the elliptical galaxies, the spiral is rich in dust and gas for the formation of new stars.

不同的是椭圆星系，螺旋是在尘埃和气体丰富的新恒星的形成。

We find that to form a helix, the Euler angle must be a constant determined by the spontaneous curvatures.

我们发现要形成螺旋形，Euler角必须为常数并由自然曲率所决定。

The fibril of cellulose macromolecules form spirals along the fiber axis.

纤维素大分子的微纤沿着纤维的轴向以一定的角度形成螺旋。

To evaluate the bioactivity of the glass-ceramics,the specimens were soaked in the simulated body fluid. The results indicate that fluorapatite shows needle-like microstructure, which is similar to that in human bone and teeth. The formation of needle-like fluorapatite is related to the heat treatment procedure, which results in needle-like fluorapatite crystals by accelerating one-dimension growth along the c-axis through the screw dislocation growth mechanism. The mechanical properties of the glass-ceramics are close to those of the human bone and teeth. The bioactivity test results show that apatite layer is precipitated on the materials surface after 3 d immersion in SBF, which indicates the glass-ceramics have a good bioactivity.

研究结果表明：氟磷灰石相呈针状，与人体骨和牙齿的磷灰石形貌相似，有利于提高材料的生物活性和生物相容性；氟磷灰石的形成是材料被迅速加热至高温进行热处理，使磷灰石以螺旋位错生长机制沿c轴晶化长大所致；经热处理获得的材料具有优良的力学性能，基本满足骨科和齿科用生物材料的性能要求；材料在体外模拟体液中浸泡3 d后，样品表面已有磷灰石层生成，表明该材料具有较高的生物活性。

These energy feather not only have own helical motion, but also have formed the whole movement.

那些能量羽在自己的螺旋运动之外，还形成了整体的运动。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
