05 continual observe for 24 hours

     Let's observe the regularity of data in 24 hours. Experiment is repeated once every 2 hours. Every time, the experimental steps were entirely the same. The detail is as follows: Adjust to make the mark M point to the south by the compass, then switch on the driving motor. After 10 minutes' the circuit would start to collect data automatically, data had been collected for 6 minutes. Next, turn the device to make the M point to the north ( It expend about 20 seconds to finish changing the device's direction during which revolving bar keep revolution continues) , data had been collected for 6 minutes again. Finally make the M point to the south to collect data for 3 minutes, So that check the repeatability of the south data.
    The following is a typical curve of  an experiment. In fact, we are more interested in the change of data when the direction of the device is changed, It is obvious that the change root in other factor except for the device itself, in other word, this change result in the space of the device. The change caused by the direction change is called "space-parameter". In the following curve, we should pay much attention to the east-west direction ones, i.e. the space-parameter of series-3--the yellow curve. Under date was collected in August 15, 2006.

    By comparing, we can find that the twelve figures above are almost consistent. The bottoms of the yellow curves are all around 500. The tops are around 1500. And their space-parameter are almost the same. In different time in a day, the curves do not obviously become more smooth or fluctuant, not to say the case of opposite phase. We show the "space-parameter" of series-3 in follow.

           
     Fig. 5.13 the data of space-parameter of series-3 in 24 hours

    In different time in a day, the space-parameter of serials3 are around 1100 all the time. The difference between the maximum and the minimum is less than 200. Taking the factor of errors into account, we can absolutely affirm that, the space-parameter of series-3 which are high to 1100 are not caused by absolute velocity. And the other experimental results are all the same.
