在用玻璃管给某井量油时,如果共计量油5次,则应该用()计算量油时间。
A. T<sub>0</sub>=(T<sub>11</sub>+T<sub>21</sub>+T<sub>31</sub>+T<sub>41</sub>+T<sub>51</sub>)
B. T<sub>0</sub>=(T<sub>11</sub>+T<sub>21</sub>+T<sub>31</sub>+T<sub>41</sub>+T<sub>51</sub>)/5
C. T<sub>0</sub>=(T<sub>12</sub>~T<sub>11</sub>)+(T<sub>22</sub>~T<sub>21</sub>)+(T<sub>32</sub>~T<sub>31</sub>)+(T<sub>42</sub>~T<sub>42</sub>)+(T<sub>52</sub>~T<sub>51</sub>)
D. T<sub>0</sub>=(T<sub>12</sub>~T<sub>11</sub>)+(T<sub>22</sub>~T<sub>21</sub>)+(T<sub>32</sub>~T<sub>31</sub>)+(T<sub>42</sub>~T<sub>41</sub>)+(T<sub>52</sub>~T<sub>51</sub>)/5
