In addition, some experience formulas for them are regressed. The third chapter establishes a unified S-N curve equation to calculate multi-axial fatigue ultimate strength of concrete considering both the effect of confinement and minimum/maximum stress ratio, based on the triaxial fatigue test data in this paper and the test results under uniaxial and biaxial fatigue loading in previous literatures. Moreover, the consistency of calculating condition fatigue ultimate strength with fatigue life distribution and initial ultimate strength distribution is analyzed.

A principal curve is used to represent the shape feature of every region. Then Hough transform is applied to these curves to detect a logarithm spiral equation which can match the curves well.

首先螺旋云帶的提取建立在對云圖恰當(dāng)分割的基礎(chǔ)上天美爱情公寓翻拍，從云團的骨架中提取出能夠反映螺旋云帶特征的局部螺旋線。

Grain quality affected by N application and plant density could directly influence malting quality. Grain protein content was negatively correlated to steeping degree and steeping rate, and positively related to saccharogenic power. The relationship of grain protein content to a -Amino-nitrogen content and kolbach index could be expressed with a quadratic curve equation, respectively. The greatest decomposition rate of protein might be achieved when grain protein content was 11-12%.
