与之相比，氢浆提高了密度和热沉，显著地减小了飞机的体积和重量。

Both the fuel density and cooling capability are increased with the use of slush hydrogen and so the size and weight of the vehicle can be significantly reduced.

但如果初始弯沉很小并在原路面结构层的设计范围内，最好不要压浆，因为压浆所造成的扰动可能会对板块的稳定性产生影响。

But if initial deflection is small and in the designed range of the pavement structures, it'd better not grout or the plate stability will be impacted by disturbance caused by grouting.

灌注桩后压浆技术解决了桩底沉淤和桩身泥皮影响灌注桩承载力的问题，使桩底、桩侧土得到了加固，从而大幅度提高了灌注桩的承载力，降低了桩的沉降量。

Problem on the bearing capacity of cast-in-place pile influenced by the deposit at pile end and the mud hanged on pile shaft can be solved by the technique with the post grouting.
