In the centrifugal compression system, the transient states from the initial period of surge inception to the full developed surge are measured and analyzed in detail. The small perturbation phenomenon, which is related to the frequency of the inherent surge in the system, is found before the nonlinear development of surge. Therefore, the causes why the small perturbation is produced are investigated mechanismically. By means of Joint Timefrequency Analysis and successive FFT data processing, a few characteristics of the small perturbation have been diagnosed at the inlet, the outlet, the plenum and the circumference of centrifugal fan. The method which is used to capture the signal of surge inception is designed.

A boundary theory is used to study the coupling behavior of double resistive tearing mode in a mulhple current layer. Simple analytic expresses for the tearing instability parameter Δ' are obtained under the first leading order, which are applicable for both linear and nonlinear development of the double tearing mode. The results show that the coupling of the two rational surfase modes always contributes a destabilizing effect to the double tearing mode. The sbength of the coupling relates not only to the disboce and initial status between the two rational surfaces, but also to the relahve developing strength of the two rational surface modes. More far away of the two rational surfaces is, weaker of the coupling strength becomes, and the weaker rational surface mode is effected more heavily by the other stronger rational surface mode. The initial nonlinear developing tendency of the double tearing mode is also investigated by using the coupling equations. The spontaneous reconnection caused by tearing mode instability in the multiple current sheet may be important for solar flare, corona heating and the coupling between the solar wind and the magnetosphere.

应用边界层理论研究了多层电流片中m≥2的双撕裂模的耦合发展行为.在一阶近似下,解析求得了环位形中撕裂模的外区匹配参数Δ,所得结论对撕裂模的线性和非线性发展均有意义.结果表明,两有理面模之间的耦合总是使双撕裂模更不稳定.耦合的强度不仅与两有理面之间的距离和平衡状态有关,而且与模在两有理面发展的相对强弱有关.两有理面相距愈远,耦合相对愈弱;发展强的有理面处的模对另一有理面处的模影响更大.本文用所得结论对双撕裂模的初始非统性发展行为进行了分析.多层电流片中撕裂模不稳定性引起的自发重朕,可能对太阳耀斑、日冕加热、太阳风和磁层耦合等有重要影响.
