其提供1微米的重复精确度,这些精确的接触开关专门设计用来设定参考点,检查公差,监测,计量和校准工作。
Offering 1 micron repeat accuracy, these precision contact switches are designed for setting reference points, checking tolerances, monitoring, gauging and calibrating tasks.
因此,OPERA团队使用了比上一次短3,000倍的质子脉冲来重复他们的实验,这样就会大大提高了中微子开始行驶时间的精确度。
Thus, the OPERA team repeated their experiment using proton pulses that were 3, 000 times briefer than last time, giving greater precision to the start time of neutrinos.
结果:除了后方骨折块大小,所有其他指标的重复性,可信度和精确度都较差,且相关性很高。
Results: All parameters showed a poor to fair reproducibility, reliability, and accuracy except the size of the posterior fragment, where good correlations were achieved.
