MD |
MD = D = (λ1 + λ2 + λ3)/3 |
FA |
FA = [(3/2) × (q/L)]1/2 = (3/2)1/2{[(λ1 - D)2+(λ2 - D)2+(λ3 - D)2]/(λ12 + λ22 + λ32)}1/2 |
RA |
RA = q/p = {[(λ1 - D)2 + (λ2 - D)2+(λ3 - D)2]1/2}/[31/2D] |
RD |
RD = (λ2 + λ3)/2 |
AD |
AD = λ1 |
Cs |
Cs = 3λ3/(λ1 + λ2 + λ3) |
p |
p = 31/2D = (λ1 + λ2 + λ3)/31/2 |
q |
q = [(λ1 - D)2 + (λ2 - D)2 + (λ3 - D)2]1/2 |

L = (p2 + q2)1/2 = (λ12 + λ22 + λ32)1/2 |
Cl |
Cl = (λ1 - λ2)/(λ1 + λ2 + λ3) |
Cp |
Cp = 2(λ2 - λ3)/(λ1 + λ2 + λ3) |
