查询词典 magnitude

A gear H62 which made in yellow brass with the same mode number m=0.34, 2mm thick and had a center hole, when the gap get C=0.5%t , and punched with compound punching die, and the dimension accuracy reached IT7, the part have a flat surface ,the verticality of tangent plane reached 89.5°, its roughness Ra magnitude are 12.5μm, height of burr are 0.10mm; and the punching part are punched with progressive die, the gap C=7%t , initial accuracy are IT11, and have an more rough surface, even can see the gap with eyes.

例如料厚t=1.5mm的H62黄铜冲裁件，选用C≤40%t单边Ⅰ类小间隙冲裁比选用C≤8%tⅢ类大间隙冲裁，冲件固定误差将加大40%～60%，精度至少降一级。此外，采有无搭边排样，冲件的误差要远大于有搭边排样冲件。无搭边排样冲件。无搭边排样冲件的精度低于IT12级，而多数有搭边排样的冲件精度在IT11～IT9级之间，料厚t＞4mm的冲件，尺寸精度会更低一些。

There are may be different relationship between the optical polarization and V-band magnitude in the different samples, which may be caused by different magnetic in their synchrotron radiation field.

对不同的样本得到的偏振和光学V波段的星等之间的相关关系不同，这可能由于他们的同步辐射区域的磁场的不同引起的。

The tempestuousness raise and descent of reservoir water level should be paid more attention to because earthquakes of moderate magnitude may be induced by the load or unload of water in a short time period. Based on 71 earthquakes of M≥3.5 occurred in Xinfengjiang region from 1970 to 2007, statistical features of the sequences have been studied.

地震与水库蓄水变化的研究表明，1965年至今该区地震活动的增强与库水位的上升没有明显的线性关系，并且M≥4.0级地震65%发生在库水位下降或由下降转为平稳波动的过程中，因此，更应关注水库卸荷阶段的地震活动。
