2.针状体;【植】交合刺;穗状花序
1.a small hard needle-shaped part, especially one of the calcium- or silicon-containing supporting parts of some invertebrates such as sponges and corals
2.a slender column of relatively cool high-density gas that rapidly erupts from the solar chromosphere and then falls back.
1.The jury is still out on how much the spicules contribute to the coronal heat, but scientists agree it's an important step forward.
人们在这些针状体对日冕层温度的贡献多寡这个问题上依旧众说纷纭，但科学家们认为这是（对谜团作出解释的）重要的一步。
2.The new observations are very exciting, but the jury is still out on the importance of spicules in the big scheme of things.
新的发现很让人兴奋，但对针状体在大局上的重要性（这个问题），大家还是莫衷一是。
3.The Type II spicules appear to be doing it everywhere, he said.
第二型针状体似乎在每个地方都在喷射，他说。
4.The key, it turns out, are called spicules, which vent hot gases, called plasma, from the sun's surface into the corona.
观测证明，（解决这个谜团的）关键是一种叫做针状体的东西，它从太阳的表面向日冕层释放出称为等离子体的高温气体。
5.Bony spicules are seen throughout the centers of ossification, making areas of spongy bone with red marrow between the spicules.
骨化中心有骨小梁构成支架，其间缝隙内充满了骨髓。
6.pedicels up to 1 cm, scabrous, tips slightly expanded with longer spicules below.
花梗可达1厘米，粗糙，有下面的更长的骨针的端部稍膨大。
7.Spicules fill the frame and are particularly evident converging on the sunspot in the lower right of the image.
图像中比较暗的部分是太阳黑子，图中最明显的针状体就聚集在其身边。
8.For the first time, small, short-lived spicules have been clocked jetting million-degree plasma into the corona.
人们第一次发现小而短寿的针状体将上百万度的等离子体喷射到日冕层；
9.Based on some simple calculations I have done, spicules account for only a small fraction of the hot plasma.
美国宇航局的太阳物理学家JamesKlimchuk说，“根据我所做过的一些简单计算，针状体只占热等离子体的一小部分。”
10.As the marrow tissue invades the cell columns, spicules of cartilage will be left.
随着骨髓组织侵入，软骨组织将被溶嗜成小梁状。
