查询词典 average deviation

NTS improved the rotation grain yield significantly while no-till without stubble retention had the worst grain yield compare to conventional tillage system.The average yield of spring wheat under NTS was 18.10%,26.21%,13.15%,2.34%and 2.38%higher than that under T,NT,TS,TP and NTP respectively.The average yield of field pea under NTS was 20.25%,30.33%,15.83%,8.82%and 10.39%higher than that under T,NT,TS, TP and NTP respectively.

这归功于NTS处理改善了土壤结构性和渗透性能，并提高了土壤水分和肥力状况，最终体现为作物产量显著提高。6年间NT处理平均纯收益为1692.44￥/ha，比T、TS、NTS、TP、NTP增加了37.52%、194.58%、9.02%、86.79%、13.99%；平均产投比为2.98，比T、TS、NTS、TP、NTP提高了0.61倍、1.28倍、0.52倍、1.10倍、0.52倍。

On the aspect of error compensation, the system using the geometric average sound pressure instead of the arithmetic average sound pressure to get the sound pressure of the measurement point. This method not only reduces the high frequency error in the sound intensity measurement, which compensates the finite difference approximation error, but also greatly reduces the computation of the sound pressure spectrum.

误差补偿方面，课题采用几何平均声压代替通常的算术平均声压来计算双传声器法的声场声压值，这样不仅可以有效的减少声强测量中的高频误差，对有限差分误差起到了补偿作用，而且还大大减小了声压谱计算中的计算量。

Secondly, in this part, we will introduce the notation of average geodesic curvature for curves in the hyperbolic plane, and investigate the relationship between the embeddedness of the curve and its average geodesic curvature. Finally, we will employ the Minkowskis support function to construct a new kind of non-circular smooth constant breadth curves in order to attack some open problems on the constant width curves for example, whether there is a non-circular polynomial curve of constant width, etc.
