大括号

第一种

f(x)=
\begin{cases}
0& \text{x=0}\\
1& \text{x!=0}
\end{cases}

$f(x)= \begin{cases} 0& \text{x=0}\\ 1& \text{x!=0} \end{cases}$

第二种

F^{HLLC}=\left\{
\begin{array}{rcl}
F_L       &      & {0      <      S_L}\\
F^*_L     &      & {S_L \leq 0 < S_M}\\
F^*_R     &      & {S_M \leq 0 < S_R}\\
F_R       &      & {S_R \leq 0}
\end{array} \right.

$F^{HLLC}=\left\{ \begin{array}{rcl} F_L & & {0 < S_L}\\ F^*_L & & {S_L \leq 0 < S_M}\\ F^*_R & & {S_M \leq 0 < S_R}\\ F_R & & {S_R \leq 0} \end{array} \right.$

第三种

\begin{equation}  
\left\{  
             \begin{array}{**lr**}  
             x=\dfrac{3\pi}{2}(1+2t)\cos(\dfrac{3\pi}{2}(1+2t)), &  \\  
             y=s, & 0\leq s\leq L,|t|\leq1.\\  
             z=\dfrac{3\pi}{2}(1+2t)\sin(\dfrac{3\pi}{2}(1+2t)), &    
             \end{array}  
\right.  
\end{equation}

\begin{tablenotes}
\item [a] \verb|\mathpzc| conflicts with \verb|\mathsf|, so here the result is in fact from \verb|\textsf|
       which gives the same result with \verb|\mathsf|.
\item [b] The useage of package \verb|eucal| can change the font appearence.
\item [c] The \verb|amssymb| package is a superset of the \verb|amsfonts| package.
\item [d] Using \verb|sans| option, \verb|\usepackage[sans]{dsfont}|, gives sans version font.
\item [e] Need the command: \verb|\DeclareMathAlphabet{\mathpzc}{OT1}{pzc}{m}{it}|
