LGV

A Study of New Chrome-Free Lignosulfonate Viscosity-Reducing Agent LGV

新型无铬木质素磺酸盐降粘剂LGV研究

The experiment results in new prototype indicate that the above method improves LGV's travel precision obviously, and is expected to be used in real LGV.

在新的模型车上的实验结果表明，这种方法明显提高了车的运行精度，可望用于实际的LGV。

Therefore, endoscopic findings combined with the LGV hemodynamics showed important value in predicting variceal bleeding in patients with esophageal varices.

内镜检查联合应用胃左静脉血流动力学指标可能对预测食管静脉曲张出血有重要价值。

The reaction temperature should be controlled in order to make LGV samples have proper average molecular mass.

合成时应对此进行严格控制和调整，使LGV产物具有合理的平均分子量分布。

Conclusion: LGV may be involved in pain regulation by releasing their contents into the synaptic cleft.

结论：LGV可能通过于突触部位的胞吐参与了痛的调节过程。

The properties of chromium-free lignosulfonate LGV in relation to its synthetic reaction time

合成反应时间对LGV无铬木质素降粘剂性能的影响

Lower average molecular weight of LGV samples was unfavourable for the adsorption and hydration.

平均分子量太小，不利于产物的吸附与水化，平均分子量太大。
