查询词典 fitting of a curve

Applying soil's nonlinear stress-stran relationships (the skelton curve adopts Hadin's hyperbola model and the loaded/unloaded curve adopts the Masing's law revised by Pyke), and taking the viscous boundary as flank artificial boundary, 2D dynamic analysis of the foundation is programed by FEM. It contains an automatic dividing-element subroutine. It could be employed to calculate the horizontal and vertical seismic responses of the soil and foundation.

But the sub-cluster scale theory was demonstrated successfully to explain the relation of cell structure and foam mechanics property on different mold temperature, mold pressure, mold period and different chemical blowing agent, blowing activator content.

通过大量的实验结果理论分析表明：以往的经典理论存在着很多不足之处，它不能有效地解释孔径、泡孔密度与抗拉强度、断裂伸长率、断裂功、及回弹率之间的理论曲线与实验曲线之间的偏差，也不能解释空隙度、泡孔壁厚与上面四者之间的关系，而群子标度理论则成功地论证了在不同模压温度、模压压力、模压时间及不同用量发泡剂、发泡促进剂条件下泡体力学性能与结构之间的相关性。

The number and intensity of peaks of the thermoluminescent cutves are obviously related to stages of gold mineralization:the curve of the early barren quartz shows nearly Symmetric pattern; that of the major stage auriferous quartz is of multimodal type; the curve of the late quartz, low in gold, is marked by unimodal--bimodal type with rather intense luminescence.

石英热发光曲线的发光峰的数量和强度与金成矿阶段有着明显的关系：早期成矿阶段结晶的基本不含金石英，热发光曲线常为近对称的单峰型，发光强度较大；主成矿阶段形成的含金石英，热发光曲线为多峰型，常具最大的发光强度；晚期成矿阶段生成的含金性较差的右英，热发光曲线呈单峰-双峰型，发光强度亦较大。

Methods. PSF 1000 analyzer was used to measure retinal image quality for eye of 26 subjects (spherical ranged from –3.00 ~-6.00Ds, astigmatism ranged from –0.75~-3.00Dc) fitted with three forms of full correction in random order : unaided eye, with rigid gas permeable contact lenses and toric soft contact lenses. The modulation transfer function curve was observed, 12 points of the MTF curve ( equivalent 12 points of LogMar VA) was used for analysis. Results.
