上面的代码可以进行如下的优化：

1. 使用`os.path.join()`代替手动拼接路径，可以保证路径的正确性。
2. 使用`with open()`语句打开文件，可以自动管理文件的打开和关闭。
3. 使用正则表达式的`match()`方法代替`search()`方法，因为`search()`方法会在整个字符串中查找匹配，而`match()`方法只会从字符串开头开始匹配。
4. 将重复的代码段抽取为函数，以提高代码的可读性和复用性。

下面是优化后的代码：

import os
import re
import xlwt

def process_file(filename, data_sheet):
    with open(filename, 'r') as f:
        data = f.readlines()
        sheet_row = 1
        for line in data:
            if line.endswith('.bin\n'):
                data_sheet.write(sheet_row, 0, sheet_row)
                data_sheet.write(sheet_row, 1, line)
                sheet_row += 1
            elif line.startswith("Tensor rate is "):
                data_sheet.write(sheet_row, 2, line[14:])
                sheet_row += 1

def main():
    file_path = os.getcwd()
    n = re.split(r'\\', file_path)
    path = os.path.join(file_path, n[5] + ".xls")
    
    workbook = xlwt.Workbook(encoding='utf-8')
    for filename in os.listdir(file_path):
        if os.path.splitext(filename)[-1] ==  ".txt":
            data_sheet = workbook.add_sheet(filename[:-4])
            data_sheet.write(0, 0, 'No.')
            data_sheet.write(0, 1, 'test_file_name')
            data_sheet.write(0, 2, 'rate_ratio')

            process_file(filename, data_sheet)
    
    workbook.save(path)

if __name__ == '__main__':
    main()

通过将重复的代码段抽取为函数`process_file()`，提高了代码的可读性和可维护性。同时，使用`os.path.join()`和`with open()`语句更加规范和安全地处理路径和文件操作。
