| 10. | However , from the definition of oscillation , the oscillation of system ( 1 ) is only an interval behavior . therefore , it is natural to think that we can study the oscillatory behavior of system ( 1 ) only on a sequence of subiiitervals of [ t _ ( 0 ) , ) , which weakens the restriction to p ( t ) , q ( t ) to a great extent . in chapter 2
但另一方面，按照振动性的定义，系统( 1 )的振动性又仅仅是一个区间性质，因此，很自然地想到，只要在[ t _ 0 ， )的一系列子区间上来研究系统( 1 )的振动性，这样就大大降低了对p ( t ) ， q ( t )的限制。 |
