## 最终结论
```python
def is_sublist(main_list, sub_list):
    sub_length = len(sub_list)
    for i in range(len(main_list) - sub_length + 1):
        if main_list[i:i + sub_length] == sub_list:
            return True
    return False

# Test cases
assert is_sublist([2,4,3,5,7],[3,7])==False
assert is_sublist([2,4,3,5,7],[4,3])==True
assert is_sublist([2,4,3,5,7],[1,6])==False
```
