Firstly, from Gauss' equations and relative motion equations, the relation of control impulse and relative motion was expressed as analysis formulas and simplified based on the near circular condition. By deeply analyzing the mechanism of impulses in each directions (radial, in-track and cross-track directions) effect on relative motion respectively, two maneuvers to establish formation flying are provided: one is to utilize the impulses in radial and cross-track directions, the other is to utilize the impulses in along-track and cross-track directions. Both of the two methods can establish satellite formation flying of any configuration. The method with impulses irradial and cross-track directions needs only 3 impulses, while the method with impulses in along-back and cross-track directions needs 4 impulses. Lastly, by an example of establishing a space-circle formation flying, two maneuvers were compared with each other in the amount of impulses and fuel consuming estimation.

On the NiO/SiO〓 catalyst prepared by IM, the main hydrogenation product of MA was SA, the activity and selectivity were almost no relation with the nickel content and nickel species 3. Summarizing the characterization and activity evaluation of the catalysts, we concluded: On nickel based catalyst, when NiO was crystallite, and the Ni〓 that was prepared by reducing, hydrogenation of the MA could lead to SA but not to γ-BL; when NiO was cluster and had a properly interaction with the support, the Ni〓 prepared by reducing, could hydrogenate MA to SA then to γ-BL. When NiO cluster and crystallite were both existed on the catalyst, the hydrogenation products were mixture of SA and γ-BL, and the amounts of SA and γ-BL were related with the ratio of cluster and crystallite.

This thesis mainly discuss following issues, Theory and simple expressions for array covariance matrixes are derived when angular spread functions are symmetric distribution functions, i. e. the Uniform distribution, the Gauss distribution, the Laplace distribution and the Von Mises distribution, and a non-symmetric distribution function, i. e. the Gamma distribution. And the relation between the effective signal subspace and the array number, or and the nominal angle of the distributed source, the angular spread, the distributed functions, and the Signal-to-Noise Ratio is gained.

A prediction model has been proposed to deal with threshold voltage shift as a function of 1MeV neutron flux and gate oxide thickness, and to deal with room-temperature annealing of threshold voltage shift induced-by 〓Coγ as a function of electric field and gate oxide thickness. The commonness and individuality of MOS device degradation between hot-carrier effect and ionizing radiation were investigated. The dependence of substrate current, gate current and threshold voltage shift due to hot-carrier on gate oxide thickness were simulated with MEDICI-2D simulator. The photocurrents of PN junction and bipolar transistor were studied. Their transient responses on varied bias voltages, pulse durations and absorbed doses were simulated. The influences of NPN base width on base and collector photocurrents were investigated. We also studied 1MeV neutron displacement damage in PN junction, and calculated reverse current leakage under the neutron flux of 2. 67×10〓 per square centimeter. 3 The study of nondestructive screening method for MOS radiation tolerance A theoretical and experimental study of nondestructive screening methods for radiation tolerance of nMOS and pMOS were firstly fulfilled. We determined the informative parameters pertinent to the method and proposed how to deal with experimental data and verify obtained results statistically, as well as make the required steps for nondestructive screening. Based on the experimental data of 180 samples of discrete pMOS devices, the relation between sample quantity and correlation coefficient, screening equation, and other significant results were obtained from the threshold voltage shifts of pre-and post-irradiation samples.

The results were found as following:(1) The damage value increases more significantly with the increase in PVF before 30% PVF, beyond which the increasing trend becomes gradually gentle.(2)Keeping the interphase strength and PVF unchanged, the damage increase with increasing moisture concentration in a nearly linear relation.(3)The results generated from the FCC model with consideration of the interphase debonding are in good agreement with the experimental data, meanwhile, the FCC model is also capable of predicting the critical load for the damaged and the undamaged dental composite subject too the 3-point flexural test.4 A 3D-fmite element analysis has been successfully exploited to examine the mechanical behavior of the restoration-tooth structure under the polymerization shrinkage and water sorption. It was found:(1) The low stiffness of the composite has the effect to limit the displacement occurring in the remaining tooth tissue. For lower interphase, the cuspal flexures are litter higher. The high interphase modulus acts as a \'shielding effect\' for stress transfer.

He has theconsciousness of the death innerly, the childhood girlfriend's deathmade Humbert think the death uniquely;the death is unique to him, Lolita is the "time" for him. the death to him is not dread anymore and itchanges into metaphysical power;he heads for the death with the relationto Lolita, because in the relation he clearly feels that the being'sabsurd and brutal, he inevitably loses the past and the future ,so thedeath is not only the release but also the surpass for Humbert.To Lolita , she finally loses her meaning when trying to use thetime. The trip to the death is the certain result for her looking downon the rule of the time;she is most interested in the future;but herexperience with Humbert in fact have killed her who should be morevigorous, she just dies on the "now" time;and it also snatches herfuture, so Lolita is just from one nothingness-condition to another;Lolita can not grow in the right meaning and her life is not full enoughbecause she can not use the time rightly. Lolita costs too much for herlife just because she bantered the time and wanted to use the time toexceed all the control.So finally, the two people's fate is the death, with the time's pushing forward.
