Then diesel fuel oil is injected or sprayed into the cylinder at the end of the compression stroke . 然后在压缩冲程即将结束时,柴油燃料被喷射或被喷雾进入气缸。
The coatings are sprayed onto the components being analyzed by using aerosol cans or compressed-air spray guns . 涂料是用按钮喷雾罐或压缩气喷枪喷到所要分析的零件上去的。
The bombardier's secretion is produced in a pair of glands-large sacs placed side by side in the beetle's abdomen . 喷雾甲虫的分泌液是在一对腺体--甲虫腹内并列的一对大液囊--里形成的。
The experiments with frogs and ants had led us to believe that bombardier beetles might be safe from all their enemies . 用青蛙和蚂蚁所作的实验曾使我们相信,喷雾甲虫可以安全地免遭所有敌人的攻击。
A more difficult problem is the quantitative description of the secondary breakup of the initial spray by high velocity combustion gas . 一个更困难的问题是关于高速燃气使初始喷雾二次破裂的定量描述。
