문장속에 간단한 수식(문자)을 넣게 되는데요... 이렇게 할때 설정된 여백을 넣어서 표시되는 경우가 있습니다.. 

어떻게 해결해야될까요?? ㅡㅜ 

도움부탁드립니다.. 

where, {${\bf{D}}_{SSP} \left( {{\bf{q}}_{exo} } \right)$} is the {$7 \times 7$} positive definite and symmetric inertia matrix, {${\bf{C}}_{SSP} ({\bf{q}}_{exo} ,{\bf{\dot q}}_{exo} )$} is the {$7 \times 7$} matrix related to the centrifugal and Coriolis terms, {${\bf{G}}_{SSP} \left( {{\bf{q}}_{exo} } \right)$} is the {$7 \times 1$} matrix of gravity terms, {$q_{exo}$}, {${\bf{\dot q}}_{exo}$}, and {${\bf{\ddot q}}_{exo}$} are the {$7 \times 1$} vectors of the angle, angular velocities, and angular accelerations, respectively. In Equation (4.10), the internal torque {${\bf{\tau }}_{SSP\_int}$} includes the coupling inertia torque, gravitation, centrifugal, and coriolis torque.
