气流

In the U.S., for example, El Nio winters feature a strong jet stream and storm track across the southern portion of the country, whereas the jet stream in La Nia years is wavelike, bringing stormier than normal conditions to the northern states.

EL Nino 冬天以强烈的气象喷射气流和暴风雪穿越国家南部地区为特征，然而在镧镍为主的年份里，喷射气流是波状的。它给北部州县带来比往常情况下更多的暴风雪。

The results show that in the formation process of tumble during the intake stroke,two vortexes are generated in the cylinder.

增加流经排气门侧的进气气流或抑制直接沿进气门侧缸壁流入气缸的气流，都能提高滚流强度。

Open-end jet spinning is a new spinning method, which works in such a way that a high-speed air current forms the open end with the aid of roller drafting, while a high-speed rotating air current inserts twist to the sliver.

自由端喷气纺纱是以高速气流辅以罗拉牵伸而形成自由端，并利用高速旋转气流对须条进行加捻的一种新型纺纱方法。

Finally, he air velocity, the velocity of the wood particle, the relative velocity between the air and the wood particle, the wood particle's residence time and the variations of the particle's velocity along radial and circle are measured. The ISD of particles is analyzed on dynamics.

最后，测量了气流速度、刨花速度、刨花与气流间的相对速度、刨花在半环内的停留时间及刨花在半环内沿径向和周向的速度分布，并地基础上进行了刨花对撞流干燥的动力学分析。

Finally, the air velocity, the velocity of the wood particle, the relative velocity between the air and the wood particle, the wood particle's residence time and the variations of the particle's velocity along radial and circle are measured.

最后，测量了气流速度、刨花速度、刨花与气流间的相对速度、刨花在半环内的停留时间及刨花在半环内沿径向和周向的速度分布，并在实验基础上进行了刨花对撞流干燥的动力学分析。

The results showed that the guided baffle plate type sprayer changed the flow field around the nozzle, which could reduce the horizontal velocity and product the down vertical airflow.

结果表明挡板导流式喷雾机改变了喷头周围的流场，使气流的水平速度减小，并产生了垂直向下的气流，减少了雾滴飘失的潜能并胁迫雾滴向靶标沉积。

For example,the spiral arrangement of scale－bract complexes on ovule－bearing pine cones,where the female reproductive organs of conifers are located,is important to the production of airflow patterns that spiral over the cone's su***ces,thereby passing airborne pollen from one scale to the next.

例如，带有胚珠的松球的鳞苞综合体的螺旋状安排，亦即松柏目植物雌性殖器官的所在位置，对于气流模式的形成与产生殊为重要，而这些气流模式在松球的表现盘旋上升，从而把在空气中飞行的花粉从一个鳞苞传播至下一个鳞苞。

The results indicate that IAQ and thermal comfort in cave dwelling with channel are close to ISO standard 7730, but the airflow distribution is not reasonable.

研究结果表明：地沟窑洞在室内空气品质和热舒适性上均已接近国际ISO7730标准，但窑内气流分布不合理；吊顶窑洞内气流分布情况较好，但进风口附近区域风速过大且温度过热。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
