The experiment result shows that, as far as the environment temperature decreases -5℃, starting resistance torque increases 2.5 N·m; starting resistance torque increases 3-8 N·m when the rotating speed increases 50 r/min.

通过ISAD柴油机起动台架试验可以看出：相同的环境温度下，起动阻力矩随起动转速的提高而增大，每提高50 r/min，每缸平均起动阻力矩增加3～8 N·m；起动阻力矩随环境温度的下降而增加，0℃以下时，每降低5℃，平均每缸起动阻力矩增加2.5 N·m。

The task of players in a warehouse controlled a stevedore who will be the same as the N box pushed to the same N as a destination.

玩家的任务是在一个仓库中操纵一个搬运工人，将N个相同的箱子推到N个相同的目的地。

The biomass of rice were not affected by partial-root water stress under those three nitrogen forms, but root parameters of sole nitrate supply decreased significantly under water stress compared to non-water stress part. Water stress stimulated the absorption of NO_3~--N. The photosynthesis rate was inhibited by water stress under NO_3~--N supply, but no effects under NH_4~+-N supply.

局部根系水分胁迫对3种供氮形态营养水稻总生物量没有明显影响，但对单供NO_3~--N营养水稻根系的生物量、根系总长、根体积、平均直径以及根表面积的影响最大，均以未受水分胁迫的一侧根系生物量明显高于另一侧。
