由细胞组成的

We see phellem below microscope, it is by by tens of thousands be just as alveolate to do cellular composition, air was filled inside the cell, formed many a airtight gasbag.

我们在显微镜下看软木组织，它是由成千上万个如同蜂窝状的干细胞组成，细胞内布满了空气，形成了一个一个的密闭气囊。

The theront, tomite and tiophont possess a complex oral apparatus, being composed of cytopharynx, oral rib, dikinetids and nematodesmata, without an organelle of Lieberkuhn which is considered as a synapomorphy of the suborder Ophryoglenina.

幼虫、幼体和滋养体均具有复杂的口器，由胞咽、口肋、双动基体口纤毛和线带等组成，但不具备膜口类纤毛虫所具有的独特的细胞器：Lieberkuhn氏器。

It is composed of dense bundles of fibres and spindle-shaped cells, with little ground substance.

It is compose d of dense bundles of fibres and spindle-shaped cells, with little ground substance.

它由致密的纤维束和纺锤形的细长细胞以及少量的基质组成。

The pituitary gland consists of neurohypophysis and adenohypophysis. Two types of pituicytes and three types of neurosecretory fibers (A1, A2 and B) have been recognized in neurohypophysis. The neurosecretory terminals contain different diameters and shape of secretory granules.

脑垂体由神经垂体和腺垂体2部分组成神经垂体组织中存在2种类型的脑垂体细胞，并可以区分A1型、A2型和B型3种类型的神经分泌纤维，其终端轴突中具有不同直径和形态的分泌颗粒；B型纤维轴突中含有许多透明小囊泡。

In this paper, we use this numerical method and adopt operator splitting method to simulate the conduction model of action potential in two-dimensional cardiac ventricle tissue,the conduction model of the action potential in two-dimensional cardiac ventricle tissue is denoted by one reaction-diffusion equation with a series of ODE describing ionic channels of cell, at the same time,we adopt the compact alternate direct implicit difference method to simulate that model,compar-ing these value results,get some conlusions.

本文中，我们利用摄动有限差分方法和算子分裂思想去模拟二维心室肌中动作电位的传导模型，该模型由一个描述细胞离子通道的常微分方程组和一个反应扩散方程组成。

Meconium. The fetal bowel contents consist of various products of secretion, such as glycerophospholipids from the lung, desquamated fetal cells, lanugo, scalp hair, and vernix.

胎粪胎儿肠内容物由许多成分组成，包括肺脏分泌的甘油磷酸脂类物质，脱落胎儿细胞，胎毛，头发和胎脂。

It is composed of lobules of pale-staining cells with abundant lipid in their cytoplasm.

它由胞质内有丰富脂质的明细胞小叶组成。

Chromosome number in all counted complete metaphases of Carassius auratus var. Dongtingking is 48. Analysis of chromosome can be divided into four sections according to the position of the centromere.

核型分析结果表明，翘嘴鲌的肾细胞染色体组是由48条染色体组成，染色体组型按着丝粒位置可分为四组，分别是中部着丝粒染色体、亚中部着丝粒染色体、端部着丝粒染色体。

Broca's area consists of large cells in the third and fifth cortical layer, but it is doubtful that this is relevant to language.

波卡区是由第三和第五皮质层的大细胞所组成，不过是否和语言有所关联仍须存疑。

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.
