线路如图所示。采用光电开关TC-3330配合数字式频率计测电风扇的转速，克服了用闪光测速仪测速时会有误测半频和倍频的可能。测速时，把风叶置于光源和光电开关之间，当光线被风叶遮住时。光电开关不能受到光照输出低电平。风叶转过一定角度后，光电开关受到从风叶间的间隙照射到的光线。输出高电平。当风叶不停地旋转时。每转一圈光电开关就得到光线间断地照射3次，因此在光电开关输出端上形成脉冲信号。该脉冲信号送到任意进制加法计数器C186的EN端。C186将其各外引脚按图6所示连接即成为三进制加法计数器。从Q2端输出三倍频的脉冲信号送到数字频率计。风叶每转动一圈，从光电开关上输出3个脉冲，经倍频后输出6个脉冲。若电风扇每分钟转N圈，每分钟就有6N个脉冲送到频率计中。由于频率计是按每秒钟多少个脉冲计数的，因而转速为N时，每秒钟输出的脉冲数是6N／60=0.1N，因此采用光电开关配合数字频率计测转速时，只要把显示的数字乘以10就是实测转速数。

Ta2O5 films were prepared with conventional electron beam evaporation and annealed in O2 at 673 K for 12 h. Laser-induced damage thresholds (LIDTs) of the films were performed at 532 and 1064 nm in 1-on-1 regime firstly, and then were performed at 532, 800, and 1064 nm in n-on-1 regime, respectively. The results showed that the LIDTs in n-on-1 regime were higher than that in 1-on-1 regime at 532 and 1064 nm. In addition, in n-on-1 regime, the LIDT increased with the increase of wavelength. Furth

P-polarization high reflectors are deposited by e-beam from hafnia and silica. 1-on-1 and N-on-1 tests at 1064-nm wavelength with P-polarization at 45° incidence are carried out on these samples. Microscope and scanning electron microscope are applied to investigate the damage morphologies in both 1-on-1 and N-on-1 tests. It is found that the laser damage threshold is higher in N-on-1 tests and nodular defect is the main inducement that leads to the damage because nodular ejection with plasma sc

4.从键盘输入n和a的值，计算a+aa+aaa+…+aa…a(n个a)的值。逻辑分析：设N=4，a=3; 3 x 10+3=>33,即aa=a x 10+a; 33 x 10+3=>330, 即aaa=aa x 10+a; 333 x 10+3=>3330,即aaaa=aaa x 10+a; 则可以设一个中间变量temp表示a 的累乘+a/(aa…a)的值。 {______} n个a 然后加上累加每次temp的值，得到结果sum. #include <stdio.h> i
