a:=TIME<=093000 and DYNAINFO(17)>4;
b:=sum(v,7)>2.2*ref(sum(v,7),1);
d:=DYNAINFO(14)<0.03;
e:=DYNAINFO(7);

a:=TIME<=093000 and DYNAINFO(17)>4;
b:=sum(v,7)>2.2*ref(sum(v,7),1);
d:=DYNAINFO(14)<0.03;
e:=DYNAINFO(7);
f:=ma(e,5);
a and b and d and f>ref(f,1);
解答如下：
A:=TIME<=093000 AND DYNAINFO(17)>4;
B:=SUM(V,7)>2.2*REF(SUM(V,7),1);
D:=DYNAINFO(14)<0.03;
E:=DYNAINFO(7);
F:=MA(E,5);
A AND B AND D AND F>REF(F,1);
B:=SUM(V,7)>2.2*REF(SUM(V,7),1);
D:=DYNAINFO(14)<0.03;
E:=DYNAINFO(7);
F:=MA(E,5);
A AND B AND D AND F>REF(F,1);
