modality

1.Conclusion We believe that LDLT combined with posthepatic IVC reconstruction using cryopreserved vena cava graft is considered to be a sound modality for IVC obstructed BCS.

结论笔者认为采用LDLT及利用尸肝IVC重建受者肝后IVC治疗BCS并肝后IVC窄的术可推荐作为一种新的术。

2.As to dynamic modality, it can always be hypothesized in a conditional protasis, is always subject to tense distinction, and does not shift its orientation under the influence of interrogation.

受到时态的影响；不会因为疑问而转移方向，指向受话者。从功能上讲，机能情态不表达说话者对话语内容的任何态度，而本身属于话语命题内容。

3.The logic analysis of anti-reality hypothesis compound sentence is to reveal its hidden logic thinking modalities which are different reasoning,counterevidence and figurative reasoning.

对反事实句的逻辑分析就是要揭示出它所蕴涵的逻辑思维,即差异推理(求异法)、反证法和比喻推理。
