Taking the fiber coupler as represent, aiming at the performanceproblem of the fiber coupler which is used in the market, such as theoptical performance differences of accepted products, technologicaloptimization and stability reflected by the low rate of finished products,how to reduce excess loss, and so on. From the view of manufacture of rheological formation, the research of experiment and theory has beendeveloped. The effects of rheological technological parameters such asdrawing speed and fused temperature on the optical performance,microstructure and the process of rheological formation have beeninvestigated. It is discovered that the present heating mode of combustinggas can\'t satisfy with the rheological manufacturing technological needof high performance fiber devices. A new resistance heating system is putforward, designed and manufactured, and a new fused biconical tapermachine is developed.

论文以光纤耦合器为代表，针对目前市场上广为应用的光纤器件存在的性能问题，如合格产品的光学性能差异，成品率不高所反映的制备工艺优化与稳定问题，如何进一步降低附加损耗等，从光纤耦合器流变成形制造的角度，分析了流变制造工艺参数如拉锥速度与熔融温度及其扰动对流变制造成形过程、微观结构与器件光学性能的影响，发现现有燃烧气体火焰的加热方式不能满足高性能光纤器件的流变制造技术要求，提出、设计并制造了一种新型的电阻加热系统和熔融拉锥机。

Result］Like most of C3 plants, the diurnal changes curve of NPR of Lonicera japonica Thunb. showed double peaks, but there were time difference in reaching the peak value between the study and previous ones. The responding mathematical model of NPR to photosynthetic valid radiation could be described by three mathematic functions , such as logarithm, linearity and binomial,but binomial function was more precise than the others. Light saturation point of Lonicera japonica Thunb. was figured out by binomial equation deduced in the study, and light saturation point was 1 086.3 μmol/(m2·s).

结果］与多数其他C3植物一样，金银花净光合速率日变化曲线呈双峰型，但在具体达到峰值的时间上与前人的结果有差异；金银花净光合速率对光合有效辐射的响应可用对数、线性、二项式3种数学函数来描述，但以二项式描述更确切；根据前面得到的二项式方程，计算出了金银花的光饱和点为1 086.3 μmol/(m2·s)。

In this paper, univariate or/and bivariate binormal model was established and its parametrers was estimated by the"method of scoring". To calculate the statistical significance of the difference between two ROC curves using any one of three distinct statistical tests: the bivariate Chi-square test, the area z-score test, and the TPR z-score test.
