Solves this symptom method to divide into the surgery and the non-surgery treats, the non-surgery treats for example the physical property treatment and the pharmacological treatment, the effect is not often good, the surgery treats may divide into the traditional surgery and micro creates the surgery two kinds, the traditional surgery method is in the lumbar vertebra fusion the pexia, although this method excised has created the lumbar vertebra narrow yellow ligament and the small surface joint, but the surgery time was long, the wound was big as well as although the lumbar vertebra fusion and fixed has removed the pathological change stage abnormal movement, but the neighbor stage's abnormal movement increased, between the awl in plate's pressure elevated obviously, the small articular process exceptionally drew back changes with the fixed stage bone quantityThe loss, causes the fixed stage vertical motion stage to draw back changes ASD[1], but new micro creates the surgery is opens a small wound in the back, and implants the interspinal to open, then solution lumbar vertebra narrow sickness question.

解决此种症状的方法分为手术及非手术治疗，非手术治疗例如物理性治疗和药物治疗，往往效果不佳，手术治疗又可分为传统手术和微创手术二种，传统手术方法就是腰椎融合内固定术，虽然此种方法切除了造成腰椎狭窄的黄韧带和小面关节，但手术时间长，伤口大以及腰椎的融合和固定虽去除了病变节段的异常活动，但邻近节段的异常活动增加，锥间盘内的压力明显升高，小关节突的异常退变和固定节段的骨量丢失，导致固定节段上下运动节段的退变ASD[1]，而新型的微创手术是在背部开一个小伤口，并植入棘突间撑开器，进而解决腰椎狭窄症的问题。

matlab sps is used to build a simulink model of single-machine infinite-bus system, and based on the simulink model, simulation on effect of pss suppressing small disturbances low frequency oscillation is carried on, and some methods of improving power system transient stability are simulated, including avr and pss, short circuit cleared rapidly, fault current limiter and single-phase auto reclose. the study unifies the simulink model to realize matlab and vb seamless integration using the activex technology, and demonstrated the matlab simulation result with the vb contact surface. this method of matlab and vb integration can make up the matlab contact surface unfriendly flaw and offers a reference for the design for cai of power system analysis course.
