通过动力三轴试验，给出了饱和砂的残余孔隙水压力的全量表达式和不同液化破坏阶段的临界孔隙水压力比的表达式。
Expressions of total residual pore pressure and critical ratio of pore pressure in different failure stages of liquefaction in saturated sand are deduced based on the dynamic tri-axial tests.
同时对稀薄燃烧、增压中冷发动机做了ECU I/O标定、怠速标定、冷启动标定、对电控系统进行全工况内点火提前角的标定、内空燃比的标定、发动机增压压力标定。
Then basic calibration such as ECU I/O calibration, idle speed calibration, cold start calibration, ignition advance calibration, air fuel ratio calibration, boost pressure calibration are conducted.
