Most of previous segmentation approachs make use of the surface curvatures or the approximative polynomial coefficients which are very sensitive to noise, but the mathematical morphological operations are robust, so another main advantage of our scheme is its good noise immunity.
以前的大多数分割方法都使用表面的曲率或近似多项式的系数,表面的曲率或近似多项式的系数的计算对噪声很敏感,而数学形态学运算具有较好的抗噪声性,因此我们的方法的另外一个优点是它具有良好的抗噪声性能。

The effects of external rare earth on growth and physiological of Chlorella ellipsoidea and Ceratophyllum demersum were studied. The results implicated that there were apparently negative linear interrelation between the concentrations of Sm, Y and the numbers of Chlorella ellipsoidea, which would best be described as polynomial interrelation at 2~40mg/L concentration range of Sm and 2~20 mg/L of Y. The LC〓 of Sm and Y was respectively 41. 36mg/L and 2. 57mg/L by statistics, which also indicated the toxicity of Y was greater than that of Sm.
外源稀土对小球藻及金鱼藻生长生理影响研究结果表明:(1)中稀土元素Sm和重稀土元素Y处理浓度与小球藻生长量之间存在明显的负线性相关关系;在稀土一定处理浓度范围(Sm为2~40mg/L,Y为2~20mg/L)内,小球藻生长量随培养时间的动态变化符合多项式相关关系;统计计算得Sm和Y对小球藻的半致死浓度LC〓分别为41.36mg/L和22.57mg/L,表明Y对小球藻的毒性大于Sm。

Assuming that the restoring force is the exponential function of the displacement and that the non-linearity is weak, a direct expression is adopted instead of Bouc-Wen differential model. Furthermore, a power series expression by the polynomial of the displacement is educed using Thaler's expandedness.
文中提出采用直接表示形式代替Bouc-Wen的微分模型,在弱非线性情况下,假定滞回恢复力可以表示为相对变形位移的指数形式,并进一步用泰勒展开的方法表示为简单的多项式形式。
