The thermodynamic systems and kinetic model suitable for the electrochemical token of the component throng in Chinese traditional medicines have been analyzed. It has been indicated that the damp oscillatory reactions in the non-equilibrium close system and open system without the supplement of dissipative substance have important significance for the throng token and analysis of chemical components in Chinese traditional medicines. Various factors influencing the electrochemical fingerprint, such as reactant species and their concentrations, electrode types, temperature, stir rate, the kind, dosage and granularity of Chinese traditional medicines, have amply been researched by the B-Z oscillatory reaction which used malonic acid as a main dissipative substance. In addition, the quantitative information about the chemical components in Chinese traditional medicines has been discussed in detail. The method and its conditions for determining the electrochemical fingerprint used in scientifically distinguishing and evaluating Chinese traditional medicines have successfully been put forward. electrochemical fingerprint, test method, conditional factor, differentiation of verity and falsity, quality evaluation, Chinese traditional medicineThe phenomena of mixing the false with the genuine and selling the shoddy medicines often take place in the market of Chinese traditional medicine (CTM), which has badly restricted the security to employ CTM and the stabilization of the curative effects, and has also restricted the developments of research and application of CTM. Therefore, none but scientific identification, evaluation and quality control performed to CTM can insure their good quality, validity, security of use, and stabilization of curative effect. Consequently, the research on scientific methods for the identification of verity and falsity, and quality evaluation of CTMs has become a problem vigorously challenging the analysts and pharmic chemists [1] . CTMs are very complex analysis systems whose most effective or active components have not been made sure. Therefore, the identification of verity and falsity, and the quality evaluation of CTMs by only employing the analytical indexes of some chemical components in CTMs are not scientific and precise, and often provide the entrance of the bastardly and low-grade products into the legal market with opportunities. Indeed, the identification and evaluation of CTMs from the results obtained by analyzing chemical components in CTMs one by one through separation, purification, spectrum techniques and other analytical methods are the most reliable methods. However, the methods are not suitable for the identification and evaluation of most CTMs with complex components due to their disadvantages such as high analysis cost, long operation flow, and burdensome workload. The analytical cost and time may be decreased consumedly by the multivariate resolution and calibration techniques of chemometrics,

We report an all-dielectric electro-optic (EO) polymer/TiO2 multilayer slot waveguide modulator with low optical insertion loss for high-speed operations. The EO polymer is sandwiched between thin TiO2 slot waveguide films to improve mode confinement in the EO polymer. The structure increased the mode confinement in the TiO2 and EO polymer slot layers and reduced the electrode distance between the Au electrodes without introducing optical loss from the metal electrodes. The half-wave voltage of the modulator was 6.5 V for a 5-mm-long electrode at a wavelength of 1550 nm. The half-wave voltage and length product was 3.25 V·cm.
