  2. ( 3 ) verifies the voltage wave, electrical current vuive and output power wave of asteroidal magneto, and the veracity of parameters by a series of experiments. the experimental result demonstrates that the error is less than 10 % between theoretic value and actual value

    ( 3 )通過一系列實驗驗證了星形磁電機空載電壓波形、電流波形、短路電流倍數、輸出功率等波形和參數的準確性,實驗結果表明,理論與實測值相差不到10 。
  3. Prepared technical parameters were optimized by l9 ( 34 ) experiment analysis. a unique method for cleaning and drying of substrate - cleaning used by scour, drying used by infrared light was fished out by large numbers of experiment. chemical mechnism of zno thin film prepared by sol - gel technique was discussed by dta for the first time. by the measurements of sem, xrd and uvs, the thin film was analysed. the result proved that the thin film with strongly preferred orientation of c - axis perpendicular to the substrate surface which surface was homogenous, dense and crackfree was the crystalline phase of hexagonal wurtzite. the thin film was composed of plentiful asteroidal crystal which crystal dimension approximately 10 30nm. the average transmittance of thin film in visible region was above 90 %. the results of measurements else also proved that the thickness of single dip - coating was 75 240nm, this films resistivity was found to be 3. 105 102 3. 96 105 ? cm. the thickness and resistivity of thin film influenced by dope - content, withdrawal speed, pre - heat - treatment, anealing were reseached respectively
