above threshold meaning in English
超临限值
Examples
- With the intensity of laser increased a series of new phenomena appears , for example , multiple photon lonization ( mpi ) , above threshold lonization ( ati ) , tunnel lonization ( tl ) , stable lonization ( si ) and so on
随着激光强度的增加，会出现一系列的新现象，例如多光子电离，隧穿电离，阈上电离和稳定化电离等现象。 - Taxpayers with an annual turnover that exceeds the above thresholds are considered as general taxpayers and should register and obtain approval from the tax authorities for this classification
凡年应税销售额超过以上所述的小规模纳税人标准的纳税人，均为一般纳税人。其应到税务机关办理税务登记并申请办理一般纳税人的认定手续。 - So they can be used for spectroscopy , coherent communication and quantum optical studies . they also can produce various kinds of nonclassical states of light generation of squeezed vacuum below threshold , of strongly intensity - correlated twin beam above threshold and quadrature squeezing of the pump wave above threshold
同时，连续光学参量振荡器也是一种产生非经典光场的理想装置：低于阈值运转可以产生正交位相压缩真空态，高于阈值运转可以产生强度关联的孪生光子对以及反射泵浦光的正交分量压缩。 - We presents a detailed studied of the linewidth of parametric light in clbo - opo caused by the linewidth of pumping beam , off axis phase matching , divergence angle of pumping , time above threshold , high gain coefficient of nlo crystal , fluctuate of cavitylength , spontaneous radiation , according to the momentum and energy conversion laws , and the sellmeier equations of the clbo , we calculated curves of the type - i and type - ii compared with the bbo ' s
根据能量动量守恒关系和clbo的色散方程，详细分析了由于泵浦光的线宽、泵浦光偏轴泵浦、泵浦光的发散角、泵浦光功率超过参量光振荡阈值一定倍数、高增益系数、有效腔长波动以及自发辐射引起的参量光线宽，并得到了与bbo晶体在类、类相位匹配下比较的理论曲线。
