这段代码中有一些错误和拼写错误。首先，`matplotlib.backends` 应该是 `matplotlib.backends.backend_tkagg`。然后，`plot` 函数应该是 `plot(t, s)` 而不是 `plot(t.s)`。此外，在调用 `button.pack(side=Tk.BOTTOM)` 之前，应该是 `button.pack(side=Tk.BOTTOM)` 而不是 `button=pack(side=Tk.BOTTOM)`。以下是修改后的代码：

import sys
import tkinter as Tk
import matplotlib
from numpy import arange, sin, pi
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
from matplotlib.figure import Figure

matplotlib.use('TkAgg')
root = Tk.Tk()
root.title("我们测试-matplotlib in Tk")
# 设置图形尺寸和质量
f = Figure(figsize=(5, 4), dpi=100)
a = f.add_subplot(111)
t = arange(0.0, 3, 0.01)
s = sin(2 * pi * t)
# 绘制图形
a.plot(t, s)
# 把绘制的图形显示到tkinter窗口上
canvas = FigureCanvasTkAgg(f, master=root)
canvas.show()
canvas.get_tk_widget().pack(side=Tk.TOP, fill=Tk.BOTH, expand=1)
# 把matplotlib绘制图形的导航工具栏显示到tkinter窗口上
toolbar = NavigationToolbar2TkAgg(canvas, root)
toolbar.update()
canvas._tkcanvas.pack(side=Tk.TOP, fill=Tk.BOTH, expand=1)
# 定义并绑定键盘事件处理函数
def on_key_event(event):
    print('you pressed %s' % event.keys)
    key_press_handler(event, canvas, toolbar)

canvas.mpl_connect('key_press_event', on_key_event)
# 按钮单击事件处理函数
def quit():
    root.quit()
    root.destroy()

button = Tk.Button(master=root, text='Quit', command=quit)
button.pack(side=Tk.BOTTOM)
Tk.mainloop()
