話不多說(shuō)，先展示計(jì)算后的結(jié)果示意圖，包括下面給的代碼，運(yùn)行計(jì)算后都會(huì)給出相應(yīng)的持時(shí)圖！

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

# 設(shè)置中文字體和負(fù)號(hào)顯示
plt.rcParams['font.sans-serif'] = ['SimHei']  # 顯示中文
plt.rcParams['axes.unicode_minus'] = False    # 正常顯示負(fù)號(hào)

# 讀取 Excel 文件
file_path = 'x.xlsx'  # 替換為你的文件路徑
df = pd.read_excel(file_path, engine='openpyxl')

# 提取時(shí)間和加速度列
time = df['Time'].values
acc = df['Acceleration'].values

# 檢查數(shù)據(jù)采樣是否均勻
dt = np.diff(time)
if not np.allclose(dt, dt[0], atol=1e-5):
    raise ValueError("時(shí)間列采樣不均勻，需預(yù)處理為均勻采樣數(shù)據(jù)")
dt = dt[0]  # 時(shí)間步長(zhǎng)
