## 最终结论
```python
def count_Odd_Squares(start, end):
    count = 0
    for i in range(start, end + 1):
        if int(i**0.5)**2 == i:
            count += 1
    return count

# Test cases
assert count_Odd_Squares(5,100) == 8
assert count_Odd_Squares(8,65) == 6
assert count_Odd_Squares(2,5) == 1
```
