qy是什么意思

Now , the valve is employed on model QY 100 H crane substituting imported valves and in mass-production.

该阀应用于QY100H型起重机上替代进口阀,现已投入批量生产.

In this paper, admissibility of linear prediction in finite populations with arbitrary rank under matrix loss function ( d-Qy)( d-Qy)' and quadratic loss function ( d-Qy)'A ( d-Qy).

本文分别在矩阵损失函数（d-Qy）（d-Qy）′和二次损失函数（d-Qy）′A（d-Qy）（A≥0已知）下研究了任意秩有限总体中线性预测的可容许性。

Conclusion: QY and YP can lower the expression of Bcl-2 but not act on P53.

结论：清毒饮、养正片确能下调Bcl-2表达，而对P53作用不够明显。
