在排版时，我想将Abstract引入到日期和contents之间，但是怎么写都排不进去。它会自动忽略掉我的排版请求，请问如何是好。 代码和效果图如下：

\begin{abstract}

We determine the sweet spot on a baseball bat. We capture the essential

physics of the ball-bat impact by taking the ball to be a lossy spring and the

bat to be an Euler-Bernoulli beam. To impart some intuition about the model,

we begin by presenting a rigid-body model. Next, we use our full model

to reconcile various correct and incorrect claims about the sweet spot found

in the literature. Finally, we discuss the sweet spot and the performances of

corked and aluminum bats, with a particular emphasis on hoop modes.
