如右下图所示,OC=60.500m,β(∠AOC0)-β1(∠AOC)=+30″,则CC0的值为()
A: +0.009m
B: –0.009m
C: –0.0045m
D: +0.0045m
A: +0.009m
B: –0.009m
C: –0.0045m
D: +0.0045m
举一反三
- 如右下图所示,OC=60.500m,β(∠AOC0)-β1(∠AOC)=+30″,则CC0的值为() A: +0.009m B: –0.009m C: –0.0045m D: +0.0045m
- 如下图所示,OC=60.500m,β(∠AOC0)-β1(∠AOC)=+30″,则CC0的值为() A: +0.009m B: –0.009m C: –0.0045m D: +0.0045m
- 如右下图所示,OC=60.500m,β(∠AOC0)-β1(∠AOC)=+30″,则CC0的值为()。[img=377x227]17e438bc41860b5.png[/img] A: +0.009m B: –0.009m C: –0.0045m D: +0.0045m
- 如图1所示OC=60.500 m , β=(∠AOC0)-β1(∠AOC)=+3”,则CC0的值为
- 红外线的波长范围为()。 A: 0.40~0.0045μm B: 0.40~0.76μm C: 0.76~1000μm D: 1~300mm
