The results indicate that the classical heat transfer mechanism is suitable for the medium wall load and the potential heat of the low-melting-point alloy is useful for high wall load.
结果表明，对于中等壁负荷，传统的传热机制是适宜的，而对于高强壁负荷，把低熔点合金的相变贮、放热机制引进到混合堆的热工学中是有意义的。
Under low to medium load levels, the valves are set for low lift and early closure to reduce pumping losses and improve fuel economy.
低中负荷水平下，阀门设置较低的升力系数和早期关闭泵损失减少，提高燃油经济性。
The wear mechanisms are changed with the load, it shows oxidation and abrasive wear at low load, abrasive and mild delamination wear at medium load, and delamination wear at high load.
随着载荷变化，磨损机制发生变化，低载荷时表现为氧化磨损和磨粒磨损，中等载荷时表现为磨粒磨损和轻微剥层磨损，较高载荷时表现为剥层磨损。
