查询词典 membranes

In addition to the cell nucleus, mitochondria, ribose and golgiosomes existing in the cells of animals and plants, this model exhibits the cell membranes of animal cells, chloroplasts, cell fluid, and plant cell walls.

在该模型中，除了动植物细胞所共有的细胞核、线粒体以及核糖体和高尔基体外，还分别展出了植物细胞所具有的叶绿体、液胞、细胞壁和动物细胞所具有的细胞膜。

Because of Robeson upper limitation, the commercially available polymeric membranes often have either high permeability or high selectivity, but not two together.

普通高分子膜因受Robeson上限的限制，往往很难同时满足高渗透系数和高选择的要求，而促进传递膜却可以突破这一限制。

The membranes were transformed from amorphous phase toα-Al_2O_3 crystalline phase by 5 hours annealing at 800℃and 910℃. At the same time, aluminum and amorphous alumina were found by XRD patterns. The membrane had little change in front side after 5 hours annealing at 800℃, while the back side was transformed from ruleless distributing to cluster distributing.

膜在800℃及910℃下退火5h后，由非晶态的氧化铝转变成为晶态的α-Al_2O_3，但同时也有铝单质和无定形结构的氧化铝存在，膜在800℃下退火5h后的正面没有太大变化，背面由无规则的分布变为簇状分布。

Both ischemia and ischemia/reperfusion injured the structures and functions of the membranes of sarcolemma and mitochondria.

两种损伤皆可导致大鼠心肌肌纤维膜及线粒体膜的结构和功能障碍。

By UV photo-polymerizing hydrophobic domains self-formed in PEG-VB aqueous solution, hydro-gel membranes were prepared with a variety of concentrations and irradiation time.

PEG-VB水溶液的自聚集行为和聚集结构与浓度有关，论文描述了两亲性大分子单体PEG-VB在水溶液中的自聚集历程。

In biological systems, membranes are usually "decorated" by glycolipids and glycoproteins which are semiflexible or even rigid macromolecules.
