The present invention provides a method for preparing biodegradable and biocompatible, porous, polymeric scaffolds for tissue engineering, which comprises the steps of: dissolving a polymer in an organic solvent to prepare a polymeric solution; mixing an effervescent salt in the resulting polymeric solution to give a polymer/salt/organic solvent mixed gel; removing the organic solvent from the polymer/ salt/ organi c solvent mixed gel; and effervescing the salt in the resulting polymer/salt gel to yield a polymeric scaffold.

一种用于组织工程学的生物可降解和生物相容的多孔聚合物支架的制备方法，该方法包括下列步骤：在一种有机溶剂中溶解一种聚合物以制备聚合物溶液；在所得的聚合物溶液中混入泡腾盐，得到聚合物／盐／有机溶剂混合的凝胶；从聚合物／盐／有机溶剂混合的凝胶中除去有机溶剂；和在酸性溶液中浸泡所述凝胶以使所述盐泡腾产生聚合物支架。

Fisher took what appeared to be a community of flittering butterflies evolving over time and saw them as a whole system transmitting differentiated information in parallel through a population.

费希尔在1929年写的《自然选择的遗传理论》（The Genetical Theory of Natural Selection，顿时受到启发。是达尔文带头把研究个体生物相应地转变为研究由个体生物组成的群体，而把种群想法转变为定量科学的是费希尔

But algae are on the other side of the great dividing line of life, that between creatures with a simple, single genome which is just a big loop of DNA sitting in the cell and those with genomes that are for the most part sequestered in a nucleus set aside for them, and cut up into multiple chromosomes.

但藻类是在生物分类的另一端，一种是简单的单基因组生物，不过是堆在细胞中的一大圈DNA，另一种，基因组大都隐藏在一个专用的核中，切割成多个染色体。

The existence of natural toxins is a fundamental phenomenon of life, it is a set of specific bioactive chemical substance, which evolved through a long period from nature. Natural toxins show multiplicities in biogenic source, chemical structure, biological function and active mechanism.

生物毒素的存在是一种重要的生命现象，它是自然生物界长期进化发展的具有特殊生物活性的化学产物，而且在生源、化学、功能、作用机制等方面表现出多重多样性。
