Materials and Methood Fig.1: Cylindrical coordinate system rotates around the z axis with an angular velocity w.
The coordinates of a point are given by r, the radial distance from the axis, q, the polar angle and z, the vertical distance from the origin [1,2].
The final result, the equation of motion for an infinitesimal yarn segment, can be written as (13) The three virtual forces that we're dealing with are: 1.

The amounts of the metals dropped with 1 ppb and 10 ppb were theoretically 1 × 1011 atoms/cm2 and 1 × 1012 atoms/cm2, respectively.
The lower limits of detection go to 1 × 1012 atoms/cm2.

For unit single-phase system, there are eight equilibrium state statistical distribution in total [1~4].
For a completely opened system’s distribution of Nr-E-V, the partition function is 1.
Therefore it is insignificant for that distribution [1].

Introduction Metakaolin(MK) is produced by calcined kaolin at appropriate temperature, so the calcine temperature and calcine time will affect the activity of MK[1-2].
The mortar strengths of compressive strengths for 28days with MK calcined at different temperatures and without MK are shown in Fig.1.
It can be seen from Fig.1 that comparing with the strengths of sample without MK the compressive strengths of sample with 10% MK are different.
