好的，以下是用 Flask 框架生成一个可以预测液体浓度的网址的代码：

import cv2
import numpy as np
import matplotlib.pyplot as plt
from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/', methods=['POST'])
def predict():
    # 读入图片
    image = request.files.get('image')
    img = cv2.imdecode(np.fromstring(image.read(), np.uint8), cv2.IMREAD_COLOR)

    # 获取图片长宽
    height, width = img.shape[:2]

    # 计算每个圆的半径
    width = max(width, height)
    height = min(width, height)
    a = int(width / 12) / 2
    b = int(height / 8) / 2
    c = int(a)
    d = int(b)
    r = min(c, d)

    # 计算圆心坐标
    centers = []
    for j in range(8):
        for i in range(12):
            cx = 2 * r * j + r
            cy = 2 * r * i + r
            centers.append((cx, cy))

    # 提取灰度值
    gray_values = []
    for i in range(96):
        x, y = centers[i][0], centers[i][1]
        mask = np.zeros_like(img)
        cv2.circle(mask, (x, y), r, (255, 255, 255), -1)
        masked_img = cv2.bitwise_and(img, mask)
        gray_img = cv2.cvtColor(masked_img, cv2.COLOR_RGB2GRAY)
        gray_value = np.mean(gray_img)
        gray_values.append(gray_value)

    # 拟合数据
    x_values = gray_values[:16]  # 16个用于训练的灰度值
    x_prediction_values = gray_values[16:]  # 80个用于预测的灰度值
    y_values = [0.98, 0.93, 0.86, 0.79, 0.71, 0.64, 0.57, 0.50, 0.43, 0.36, 0.29, 0.21, 0.14, 0.07, 0.05, 0.01]  # 16个液体浓度值

    # 使用numpy的polyfit函数进行线性拟合
    fit = np.polyfit(x_values, y_values, 1)

    # 使用拟合系数构建线性函数
    lin_func = np.poly1d(fit)

    # 生成新的80个数据的x值
    new_x = x_prediction_values

    # 预测新的80个数据的y值
    new_y = lin_func(new_x)

    # 输出预测结果
    result = list(new_y)
    row3 = result[:8]
    row4 = result[8:16]
    row5 = result[16:24]
    row6 = result[24:32]
    row7 = result[32:40]
    row8 = result[40:48]
    row9 = result[48:56]
    row10 = result[56:64]
    row11 = result[64:72]
    row12 = result[72:80]
    prediction_result = {
        "第三列": row3,
        "第四列": row4,
        "第五列": row5,
        "第六列": row6,
        "第七列": row7,
        "第八列": row8,
        "第九列": row9,
        "第十列": row10,
        "第十一列": row11,
        "第十二列": row12
    }

    return jsonify(prediction_result)

if __name__ == '__main__':
    app.run(debug=True)

启动 Flask 应用程序后，你可以向 `http://localhost:5000` 发送 POST 请求，请求体中包含一个名为 `image` 的文件，表示要预测的图片。应用程序将返回一个 JSON 对象，其中键值对表示预测结果。
