通过使用SPSS13.0统计分析软件对科左后旗经济综合实力进行因子分析和曲线回归分析，得出该旗综合实力因子得分较低，而农业及社会消费水平因子得分较高。

Table 6 also indicated that at 2 levels of N, their relationship with the K application was curvilinear

表6还显示，两个施氮水平下，它们与施钾量有曲线关系

The result shows that the flux distribution curve of the horizontal well is concave and the change of the pressure is small.

结果表明：水平井水平段的流量分布成明显的"凹"型曲线，其压力分布变化较为平缓。

Based on theoretic research, rotary-ditch machine is produced and orthogonal test is carried out in the farm. By variance and extreme deviation analysis on the test result, all the influence factors on ditcher casting performance are gained, superior level and optimum combination are found out, relation curve of performance target along with factor change is provided.

在理论研究的基础上，设计并制作开沟部件，在田间对其进行了正交试验，对试验结果进行极差分析和方差分析，得出各因素对开沟抛土性能的影响，找出各因素的较优水平和最优组合，并给出性能指标随各因素变化的关系曲线。

Results: Regression equation of standard curve was A=151.33+87136x (r=0.9999), and linear range was between 0.0418 and 0.2508μg; the average recovery was 99.4%. The results of the tissue distribution demonstrated that harmine levels in stomach, lungs, liver, brain and heart in the emulsion group were higher than those in the suspension group, with the highest conc entration in stomach.

结果：方法学考察表明，标准曲线回归方程为A=151.33+87136x（r=0.9999），线性范围0.0418～0.2508μg，平均回收率99.4%；小鼠体内试验显示，harmine乳剂组在胃、肺、肝、心等脏器中的药物分布均高于混悬液组，且胃内harmine水平大大高于其他脏器，并在较高浓度维持较长时间。

The growth dynamics of leaf length on stem and tiller could be described with a logistic model, leaf width with conic equation, and leaf shape with exponential function and quadratic equation. The effects of nitrogen and water conditions on leaf growth were quantified by the effective values of leaf nitrogen concentration and water content.

模型采用Logistic方程描述了水稻主茎及分蘖叶片随生长度日的动态伸长过程；利用二次曲线描述了叶宽随GDD的动态变化过程；分别用幂函数和一元二次方程描述了叶形的动态变化过程；另外，以叶片氮素和水分因子分别描述了不同水氮水平对叶片形态建成过程的定量影响。

The correlative relationship between three hyperspectral parameters and chlorophyll content of Festuca arundinacea, Lolium perenne, and Agrostis stoloni fera was studied. The result indicated that the hyperspectral parameters were significantly correlated with the chlorophyll content, especially for GNDVI.

通过3种草坪草高羊茅，多年生黑麦草和匍匐翦股颖反射光谱曲线特征，研究了高光谱参数绿峰反射率Rg、红谷反射率Ro和GNDVI与叶绿素含量的相关性，结果表明：3种高光谱参数与叶绿素含量的相关性均达到显著水平，尤其是GNDVI与叶绿素含量之间的相关性最好。
