Various labeled technique that have been applied in immunoassay presently was introduced,including labeled radiation,labeled enzyme,labeled luminophor,labeled fluorescein,labeled colloidal-gold and labeled paramagnetic-particle along with their principle characteristic and actuality of immunoassay,and their prospects were also discussed in this paper.

A path in SLSNET (subcarrier label switching network)must be hedged with qualifications for subcarrier label assignments very similar to the constraint condition of wavelength assignment in DWDM optical transport networks without a wavelength changer.

Application of molecular marker techniques in invasion ecology;

Research progress of using molecular marker technique to identify propionibacterium;

Molecular marker technique,such as RAPD、AFLP、SSR、ITS et al,provides efficient tools for bio logical gerrn-plasm and germplasms relative relationidentificating,and analyses the evolution of systern、population geography patterns、heteropopulation dynamics etc.

[Objective] To analyze how to use DNA molecular marker in the following aspects:analyzing the genetic diversity of medicinal plants,studying the relation between medicinal plants,discovering new resources,protecting the Chinese drug materials,et al.
