Newton to humanity's contribution is huge, just like Engels said:"Newton as a result of invented law of universal gravitation to establish the science astronomy; As a result of has carried on the light decomposition, but established the science optics; As a result of established the binomial theorem and the infinite theory established the science mathematics; As a result of has known the strength essence, but established the science mechanics".

In the probabilistic model for wind farm, the uncertainties of wind speed is takes into account, and the real power injected and reactive power absorbed by the wind turbine are described as the function of the voltage magnitude, the slip of the induction machine and the circuit parameters of the wind turbines. In the unified iteration method, the slip of induction machine is introduced as the new correction value. The Newton-Raphson algorithm is used to solve the unified iteration of state variable and slip. Thus, the proposed method retains the quadratic convergence of the Newton-Raphson algorithm.

The compound solution performs as pseudo-fictile fluid, and its visual viscosity is reduced when the shearing velocity increases. The higher the cationic degree of CPAM, the more apparent the rarefying behavior of the polymer-surfactant complex, but it still is pseudo-fictile fluid. In addition, such factors as the molecular weight of CPAM, temperature and PH value etc, have different effect on the properties of the mixed solution, including its visual viscosity, conductivity, rheological behavior and so on.
CPAM/SDS复合体系的表观粘度随剪切速率的增大而下降,即具有剪切变稀行为的特性,表现为拟塑性流体:CPAM的阳离子度越高,它与SDS形成复合体系剪切变稀的行为越明显,但体系的流动类型不发生变化,仍为拟塑性;随着CPAM分子量的提高,复合体系的非牛顿性增强;温度的升高将导致复合体系的粘度显著降低,非牛顿性减弱;对于SDS用量低于等电荷当量的复合体系,pH值的变化对其流变性的影响不显著。

A multi-distance measurements method is employed in this paper. A single parameter fitting method and a double parameters (reduced scattering coefficient and amplitude factor) fitting method on the basis of the least square Newton fitting algorithm is used to derive the optical parameters respectively. For the finite-thickness homogenous tissue, it can be concluded that the rest terms in expressions of diffusion reflectance and transmittance for the corresponding tissue geometries that subtract the exponential term contained source-detector distance depend on the detected position weakly.
