平均温度误差

Correlation for isothermal oil compressibility was developed as a function of temperature, pressure and density data.

并建立了温度、压力和密度函数的原油压缩系数关联式，其对404个数据点的平均误差为2.96％。

The solutions were found to be good agrees with experimental results. The transfer characteristic of air dry/wet bulb temperature and spraying water temperature were discussed. The LMTD method based on this mathematical model is applicable to design and verify for the plate wet air cooler. The ratio of the wet bulb heat transfer coefficient to the heat transfer coefficient under air-cooled conditions was investigated theoretically and experimentally. The relative errors of the ratio between theoretical and experimental valves are small than 7 percent.

分别得到了平行流型式微分方程组的解析解与交叉流型式的近似解析解，实验验证了该解析解具有较高的计算精度；探讨了空气干湿球温度与喷淋水温的迁移特性；分析得到基于湿球温度迁移模型的对数平均温差法在湿式空冷器的设计与校核计算中是适用的，给出了空气湿球换热系数与空冷时空气对流换热系数比值的理论与实验确定方法，比值系数理论值与实验值比较最大相对误差小于7％。

For the FA, the results indicated that the VPD calculation using mean of 24 hourly temperature values as saturation vapor pressure, and wet-bulb depression as actual vapor pressure yielded the lowest error, the least range, and the most frequency with the highest WI. These outcomes were as well as the SIA with the lowest EMSE, R^2 higher than 0.99 and the highest CE.

分析结果显示，以频率分析法而言，各地农业气候分区均呈现，VPD计算式以24个时温度日平均为饱和蒸汽压力，与湿球下陷量为实际蒸汽压力，具误差最少、全距最小、出现频率最多及最高权重指数，性能表现最佳，这样的结果，对照统计指标法之检测评估，同样具最低RMSE、R^2值0.99以上及最大CE，性能表现优於其他所有VPD计算式，两者，结果一致。

New molecular parameters of 18 alcohol-amines were obtained by fitting saturated vapor pressures and liquid densities at different temperatures.The overall average deviations of saturated vapor pressure and liquid density were only 0.94% and 0.88% respectively.

通过关联不同温度下醇胺的饱和蒸气压和液体体积得到了18种醇胺流体的分子参数，新方程计算的饱和蒸气压和液体密度总的平均误差分别为0.94%和0.88%。

Al addition,blowing oxygen,alloy addition and the initial temperature of the vacuum vessel wall have more effect on the temperature of molten steel.

采用该模型预测了精炼结束时刻的钢水温度，与生产中钢水温度平均误差在±5℃以内的占80％。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
