Times of this order are deduced directly by measuring the length of the particle track in a bubble chamber.
这样量级的时间是通过测量粒子在气泡室中径迹长度直接得到的。The errors of the stand-off measurement and measurement errors made by pitch diameter gauge and ovality gauge are analyzed and compared.
分析比较了紧密距测量以及中径和椭圆度量规测量的误差。pitch diameter, pitch point, addendum circle, dedendum circle, addendum, dedendum, circular pitch, diameter pitch.
中径，螺距点，增编圆，齿根圆，增编，齿根，间距圆形，直径间距。For Screw Thread Micrometer, it only measures the pitch diameter of an external or internal thread.
螺纹千分尺只能测量于外或内螺纹的中径。In addition to pitch diameter variations, there may be slight different in the degree of drag at full engagement versus partial engagements.
另外由于中径的变化，也可能在全部旋入与部分旋入时，阻力会略有不同。refers to the hardcover case-making location of spinal surrvey and spinal between stick a piece of paper or fabric lining.
指在精装书壳中腰位置的中径与中腰之间另粘上一张纸张或织品的内衬。Turn the adjusting screw clockwise, which opens the ring to a larger pitch diameter than the setting plug.
顺时针调节螺钉，这使环规开口，并使中径比校对塞规的大。A simple qualification criterion of regular pitch diameter
