The neurological defect scores in patients with acute cerebral thrombosis were positively correlated with plasma and cerebrospinal fluid concentrations oft-PA and PAI-1 antigen.
脑血栓形成组病人神经功能缺损评分与血浆及脑脊液t -PA、PAI -1抗原含量呈正相关。
2
Plasma produced in laser welding process has shielding effect to the laser beam and decreases the melting depth on even result in the defect.
激光焊接过程中产生的等离子体对激光束有屏蔽作用，降低了焊接熔深，甚至出现缺陷。
3
Comparing with the plasma spurt welding layers, the laser cladding layers had lower defect rate and higher product rate.
