And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.

Equation of regression of its standard curve is: Y=0.02909x+0.03984, correlation coefficient is 0.9999. 4 kinds of sample detect result, in binding hoof, puke, banger, cantaloup inferior nitric acid content is respectively 0.015, 0.362, 0.011 with 12.54 G/kg.

其标准曲线回归方程为：y=0.02909x+0.03984，相关系数为0.9999.4种样品检测结果，捆蹄、呕吐物、香肠、香瓜中亚硝酸含量分别为0.015、0.362、0.011和12.54 g/kg。

The results showed that it was unsatisfactory for the whole samples to estimate the LAI, with the correlation coefficient being only 0.523. After the total samples were divided into four vegetation types, i.e., meadow vegetation, marsh vegetation, shrub and islanded forest, the correlation coefficients and the estimation accuracy were improved evidently. Cubic equations were found to be the best in the different forms of the regression models for retrieving the LAI of wetland vegetation by using CBERS data, with the R^2 value being 0.723, 0.588, 0.837, and 0.720, respectively.

结果表明，整个研究区样本总体的LAI估算效果不太理想，其NDVI与LAI的相关性仅为0.523；将研究区分为草甸、沼泽、灌丛和岛状林4种湿地植被类型，NDVI与各植被型LAI的相关性和估算效果均有很大程度的提高，所建立的LAI遥感反演模型以三次曲线回归方程拟合精度最高，R^2分别达到0.723、0.588、0.837、0.720。

The quadratic regression orthogonal rotary method was adopted to study the offect of three different mixing homogeneity : mixing time, block coefficient and rotary speed of the paddle shaft, also study the dominant effect, the single effect and interactive effect.

通过二次回归正交旋转组合试验，对影响翻转式双轴桨叶混合机混合均匀度的3个因素(混合时间、充满系数及桨叶轴转速)以及对混合的主效应、单因素效应、两因素间的交互效应进行了分析，并且得出了各因素水平间的最佳组合工艺。

And the "three-factor quadratic regression orthogonal rotary method" was adopted to study mixing performance of the mixer,after the machine had been designed and trial-produced. It was showed that the optimum technological parameters for mixing time, block coefficient and rotary speed of the paddle shaft were 180 s, 0.75 and 56 r/min, respectively. At the same time, the remains in the bin was little (0.015%). The effe...

为了提高双轴桨叶混合机的混合性能，采用二次回归正交旋转组合试验，对设计样机进行混合均匀度及机内残留率的试验研究，得出了其工作参数的合理组合：混合时间为180s，充满系数为0.75，桨叶轴转速为56r/min；机内残留量极小(约为0.015%)，满足其作为配合饲料生产，尤其是预混合饲料生产的工艺要求，也为进一步改进设计提供了依据。
