The dult stem cells abilities of differentiation, self-renewing and self-maintenance tended to be limited so that it, which is characterized of short life time, could differentiate by means of mono-direction or double direction. What is the most important is that it can not differentiate all cells from the three embryonic layer.

On the basis of the presented hydroelastic theory, a computer code HEAF (Hydroelastic Analysis Program for Fast Sea Transportations) is developed to calculate wave loads and dynamic responses of mono-or multi-hull high speed vessels in the frequency and time domain.

The amphiphiles, 4-8, can not form reverse bilayers in organic solvent, which result in that the molecular interactions unable to meet the need for hydrophile-lypophile balance, so that they crystallize and exhibit no gelling abilities. The mono-chained L-alanine derivatives, 1-3, can self-assemble into bilayer aggregates, through intermolecular hydrogen bonding and homochiral effect in a number of organic liquids, which are juxtaposed and interlocked by van der Waals interaction, and finally gelate the organic liquids.

单链酰基化L-丙胺酸两亲物1-3在一些低极性的有机溶剂可以通过分子间氢键相互作用及同手性聚集作用形成有序的反双分子膜结构，这些有序反双分子膜结构单元依靠vander Waals力相互作用可以平行排列且相互之间进行连结形成长纤维状的聚集体，纤维状聚集体在有机介质中可以进一步相互连结形成三维网状结构，进而胶凝有机溶剂。

These compounds are of substantial interest both inviewpoints of theory and practical applications, mainlyunder the stimulus to achieve synthetic models either foractive sites of iron-sulfur proteins or for transitionmetal catalysts. This thesis describes the synthesis, structures andconformations of 51 new iron-sulfur cluster complexes,which have been characterized by elemental analysis andstandard spectroscopic methods. In addition, single-crystalX-ray diffraction analyses were performed for 4 representa-tive new compounds. Reactivities of μ-〓 with mono- and di- Grig-nard reagents derived intermediates toward various organicelectrophilic substrates were studied, along with complexa-tion of arynyl-containing iron-sulfur clusters by 〓Thus, several bridged, non-bridged, monomeric, dimeric,homonuclear, heteronuclear iron-sullfur and iron-sulfur co-balt-carbon cluster complexes were synthesized. A novelreaction and convenient route for the synthesis in highyield of tetranuclear iron complexes 〓 containing atetracoordinated sulfur atom was discovered, whereas aplausible mechanism based on experimental results was propo-sed for the formation of the new cluster type.
