The bifurcation and chaos behavior of impact and rubbing fault rotor system caused by the parameters of nonlinear rigidity, rotor rotating speed, eccentric mass is analyzed, in the numerical value analysis method. The bifurcation diagrams, maximum Lyapunov exponent diagrams, Poincaré maps, phase plane portraits, trajectories of journal center, time-history curve, amplitude spectra diagrams of the rotor motion are used. The convert and evolution course of periodical response, quasi-periodical response, double-periodical bifurcation, chaos of the system response is analyzed.(3). It is deduced that the general differential equation of bending-torsional-pendular coupling vibration about rotor with the gyroscopic moment. On the basis of this equation, the general differential equations of coupled bending, torsional and pendular nonlinear vibration about rotor with unbalance character and rubbing character are deduced.

Among them,a strain saccharomycete Dfjm-1 with high flocc ulating activity was obtained.The microbial flocculant of Dfjm-1 produce is na med Dtjm-1.In this paper,time course of flocculants production including growt h,flocculating activity,and pH were studied.

本文研究了&Dfjm-1&在不同培养时间的生长情况、培养液中pH值变化情况及絮凝活性变化情况，得出絮凝活性与菌生长量呈正相关关系，絮凝剂&Dtjm-1&在菌生长稳定后期达到稳定活性的最高值。

In the course of reduction at about 1000℃,Fe_2O_3 and then Fe_3O_4 was almostcompletely transformed into Wüstite within a few minutes prior to the formationof metallic iron;but the reduction of Wüstite to metallic iron lasted a much lon-ger time.

在1000℃左右的还原过程中，在金属铁出现之前，在数分钟内Fe_2O_3和Fe_3O_4几乎都已全部还原成浮士体，但后者还原成金属铁的阶段，则须经历数十分钟之久，因此后一阶段便成为还原过程中控制的一步。

In the course of reduction at about 1000℃,Fe_2O_3 and then Fe_3O_4 was almostcompletely transformed into Wüstite within a few minutes prior to the formationof metallic iron;but the reduction of Wüstite to metallic iron lasted a much lon-ger time.Therefore the last stage reaction controls the whole reduction process.

In the course of this rise and fall,the royal rorce occupied a political dominantposition for a long time and carried out a series of liberal political,economic andsocial reform unconstrainedly,so that the development of the two industrial classes wasgreatly limited and the realization of the political democracy was always hindered.Furthermore,this kind of tendency has been strengthened by the German obedient nature.

在这一起伏跌宕的过程中，王朝势力长期控制着政治统治地位，并主动实行了有限的自由主义改革，颁布了一系列社会保障措施，两大产业阶级的发展由此受到极大限制，政治民主也迟迟不能真正实现，德意志民族根深蒂固的服从意识则强化了这一趋势。
