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。

In this study the aboveground green weight, moisture and the carbon content of fifteen 46-year old Norway spruces were measured, and two approaches for calculating the aboveground carbon content of trees were discussed: the common methodology of applying expansion and conversion factors as well as using optimized regression equations.

HDL reference, in which 1μg apoAI was thought of as one activity unit, was prepared by ultracentrifuging.

测定时，以超速离心制备的HDL参考品为标准，按每1μg apoAI为1个HDL活性单位，由参考品的光吸收值和相应的活性单位数，求出HDL生物活性标准曲线的双对数回归方程，并由样品的光吸收值计算HDL制剂的生物活性。

Results The linearity range was 5~500μg/mi. The linear regression formula was Y=5.9601 X -1.643, r=0.9998. The limit of detection was 0.5μg/ml. The minimum detectable concentration was 0.04mg/m^3 (60 L sampling volume). The sampling efficiency was 100%. The sample could store at least 5 days in absorption pipette.

结果 所建方法的线性范围5~500μg/ml，回归方程Y=5.9601 X-1.643，r=0.9998；方法检出限0.5μg/ml，最低检测浓度为0.04mg/立方公尺（采样体积60L计）；采样效率达100%；样品在吸收管中可稳定5d。

The results show that: Liaodong Bay area of winter sea ice and temperatures have a significant negative correlation and the correlation of -0.815, by the regression equation between the two can forecast future trends in sea ice area.

结果表明：辽东湾冬季海冰面积与气温有着显著的负相关关系，相关系数为-0.815，通过二者之间的回归方程可预估未来海冰面积变化趋势。

The test results showed that when the cycle water flow was 65m^3/h and the oxygen flow was 1, 2,……, 10L/min, the relationship between the dissolved oxygen and oxygen flow in the water was y=0.1009χ^2+0.0594χ+5.9588 (r=0.9927). According to the mass balance principle, the maximum oxygen utilization rate of oxygen cone was calculated at 84.56%. Under the condition of the maximum oxygen utilization rate of oxygen cone, according to the rate of Nile tilapia oxygen consumption, the number of oxygen cone was projected in industrialized fish farming system. It provided the basis for oxygen supply system design in industrialized fish farming system.

结果表明，在循环水流量为65 立方公尺/h，水温24.5℃，氧气流量为0， 1， 2，……，10 L/min的条件下，溶氧与氧气流量回归方程为y=0.1009χ^2+0.059 4χ+5.958 8(r=0.9927)；根据物料平衡原理，推算出氧气锥的最大氧气利用率为84.56%；在最大氧气利用率的条件下，依照尼罗罗非鱼的耗氧率计算模式，推算出工厂化养鱼系统需配置氧气锥的台数。

Results Among the 38 pedigree charts, 44.7 percent of the diabetics had the background of family tree and 25 symptoms were listed out which were illustrated by a typical pedigree chart. The difference between the total score of kidney-deficiency syndrome with and without family tress is statistically significant (P.05). The total score of four-diagnoses showed a linear correlation with the kidney-deficiency and the regression equation was =
