This papar presents preliminary assessment about spin stabilization of satellite-launcher upstage and analyses the influence of the interference factors. The calculated results indicate that the deviation of satellite insertion point orbit parameters not only depends on the character and the influence degree of the interference factors; and relates to the spin speed of satellite-launcher upstage as well. The correct determination of the spin speed of the launcher upstage can diminish the influence...

This papar presents preliminary assessment about spin stabilization of satellite-launcher upstage and analyses the influence of the interference factors. The calculated results indicate that the deviation of satellite insertion point orbit parameters not only depends on the character and the influence degree of the interference factors; and relates to the spin speed of satellite-launcher upstage as well. The correct determination of the spin speed of the launcher upstage can diminish the influence of the interference factors on the insention point orbin parameters.

本文讨论卫星运载火箭末级自旋稳定问题,分析了干扰因素的影响。计算结果表明:卫星入轨点轨道参数的偏差,不仅依赖于干扰因素的性质和作用的大小,而且与末级火箭的转速有关;合理地选择末级火箭的自身旋转速度,可以减少干扰因素对入轨点轨道参数偏差的影响。

The dissociation and Laccase-catalyzed oxidation of six catechols containing tertbutyl group were investigated spectrophotometrically under pH 6.0~8.0 conditions. The studies show that in the presence of tert-butyl group,not only to bonding of these substrates is improved,but through the influence of the microenvironment effect of laccase,the dissociation of these substrates is promoted and the enzymatic reaction can take place under condition of weak acidity(pH 6.0), which is far from the first-order dissociation...

The dissociation and Laccase-catalyzed oxidation of six catechols containing tertbutyl group were investigated spectrophotometrically under pH 6.0~8.0 conditions. The studies show that in the presence of tert-butyl group,not only to bonding of these substrates is improved,but through the influence of the microenvironment effect of laccase,the dissociation of these substrates is promoted and the enzymatic reaction can take place under condition of weak acidity(pH 6.0), which is far from the first-order dissociation of these sub-strates. Because of the influence of the characterization of tert-butyl group and the microenvironment effect of laccase, these substrates can be transformed by laccase into corresponding o-quinones at pH 6.0,and they have a synthetic value,Moreover,using ESR-spin stabilization technique,the o-semiquinone anion-radicals generated during the enzymatic reaction were trapped in pH 6.0,and the superfine structures of the ESR spectra were discussed.The result demonstrate that the Laccase-catalyzed reaction of these substrates underwent the stage of the proton transportation and one-electron oxidation.

对6个含叔丁基的儿茶酚类底物的离解和漆酶催化氧化反应进行了考察。结果表明:叔丁基的存在,有利于增进对底物的结合,并可以利用漆酶活性中心周围提供的pH环境和质子载体性质,促进底物的离解,使这类底物能在远低于其一级离解的弱酸性环境中进行反应。由于叔丁基的特性和漆酶的微环境效应的共同作用,这些底物在pH=6.0的水溶液环境中都能顺利地氧化成相应邻醌,并具有合成价值。ESR结果证明:这些底物在弱酸性条件下的漆酶催化反应经历了质子转移和单电子氧化步骤。

The prereguisite for correct attitude control for a spin Stabilization satellit is the computation of attitude parameters of the satellite with high precision.Based on the least square (LS) approaches,a series of recursive LS algorithms are built in this paper,which are fault tolerant and can be used on line.It is shown that these algorithms are eminent statistically.
