这段代码无法正常运行的原因是，params参数被错误地添加到了请求的URL中。正确的做法是将params作为requests.get()函数的参数传递，而不是将其作为URL的一部分。

以下是修正后的代码：

import requests
import time

headers = {
  'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36',
  'referer': 'http://fund.eastmoney.com/400015.html?spm=search'
}

params = {
  "callback": "jQuery18303118265739643302_1690164521076",
  "fundCode": "400015",
  "pageIndex": "6",
  "pageSize": "20",
  "startDate": "",
  "endDate": "",
  "_": "1690165052233"
}

url = 'http://api.fund.eastmoney.com/f10/lsjz'
res = requests.get(url, params=params, headers=headers)

LSJZ = res.json()['Data']['LSJZList']
for i in LSJZ:
  print("单位净值：", i['DWJZ'])

这样修改后的代码会将params参数正确地传递给requests.get()函数，并且使用正确的URL进行请求。然后可以成功获取数据并打印出单位净值。
