It was faster than ethernet and didn ' t have some of ethernet ' s initial problems , such as packet collisions 它比以太网快而且避免了以太网的一些问题,例如数据包冲突。
New existence results are presented for the first - order nonlinear singular initial problems . here the non - linearity can change the sign 摘要获得了一类一阶可变号非线性奇异初值问题的新结果。
The initial problems created widespread public criticism , which in turn led to three separate enquiries being held 新机场在启用初期出现问题,备受社会人士批评。各有关方面随即进行了以下三项独立调查
