喷嘴

A certain type of nozzle spray cooling effect has been simulated, simulated and measured results agree better.

对某种型号喷嘴的喷淋冷却效果进行了模拟，模拟结果与实测结果吻合得较好。

The jets may also adjust the size of the sample core.

喷嘴还可调整标本芯的尺寸。

The sample core may be adjustable in position within the channel with one or more jets or channels of fluid being injected into the flow channel.

通过被注射进流通道的一个或多个喷嘴或通道的流体，可调整标本芯在通道之中的位置。

The results showed that increasing nozzle radius and number of nozzles could expand corona region and strengthen discharge intensity.

结果发现：喷嘴半径和个数的增加能够扩大电晕区域，同时提高放电强度。

The cover plate has a cover plate opening into which one or more of the nozzles may extend.

所述盖板具有一个或多个所述喷嘴可伸入其中的盖板开口。

Where A is the nozzle cross-sectional area, v is the velocity of the flow.

如果是喷嘴的截面积， V是速度的流动。

It is found that there is a critical value (25mm) for the distance from the nozzle to the skin surface when the spray time is 40 ms. If the distance is too far or too near, heat extraction process will have different characteristics. The results could provide an applicable method for guiding the Cryogen Spray Cooling of laser therapy.

发现喷雾时间在40ms时，喷嘴到皮肤的距离具有一临界值（25mm），大于或小于此距离喷雾与皮肤的换热作用具有不同的特性，研究结果对于将制冷剂喷雾冷却实际应用于激光治疗鲜红斑痣手术具有重要的指导意义。

The cooling process involves complex droplet evaporation, strong convective heat and mass transfer, therefore a deep understanding of spray characteristics is essential to optimize the nozzle design and improve the cooling efficiency of the spray. This paper presents a theoretical model to describe the equilibrium evaporation process of a single droplet in cryogen spray.

为了深入了解制冷剂喷雾特性以提高冷却效率、优化喷嘴设计，利用质量传递数法推导传质方程，通过选取合适的阻力系数经验关联式建立了动量方程，考虑液滴蒸发以及与环境气体的对流换热建立了液滴能量方程，初步建立了单个制冷剂液滴平衡蒸发阶段蒸发冷却理论模型。

Results show that thickness and width decrease with the wheel speed, and increase with the nozzle diameter.

结果表明，薄带的厚度随辊面线速度V的增大而减小，随喷嘴孔径的增大而增大，薄带的宽度随辊面线速度增大而减小，随金属熔体喷射流量的增大而增大。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
