压力喷嘴

The method of characteristics was introduced to calculate the flow field after the primary nozzle exit, whilst Korst's recompression criterion was adopted to determine the corresponding cell pressure, and one-dimensional control volume method was employed to analyze the downstream flow field.

该方法采用特征线方法分析一次流喷嘴出口流场，结合Korst再压缩判据确定引射器盲腔压力，采用一维控制体方法计算第二喉道引射器的下游流场。

The important result is that a pressure exists on the nozzle base that partially offsets the truncation loss.

重要的结果是一种压力存在于喷嘴基地，部分抵消了截断损失。

The experimental results show that the mean particle size of griseofulvin precipitated by RESS is smaller than 1, 0μm, narrow distribution and 95％ fine particles is smaller than 1. 0μm. Increase of the pre-expansion pressure, the extraction temperature, the expansion chamber temperature, the spraying distance, the concentration of cosolvent and decrease of the nozzle diameter resulted in decrease of the particle size under the operating condition studied. Enhancement of the pre-expansion temperature resulted in increase of the particles size. The SEM of GF shows that the shape of original is atactic and a wide size distribution, but the microparticles obtained by RESS is reverse. Similar melting points and XRD patterns were observed for the original material and the precipitates obtained by RESS.

实验结果表明，用含夹带剂的RESS法制备的灰黄霉素微粒的平均直径在1μm左右，且分布均匀，95％微粒在1μm以下，仅用CO〓作为超临界流体制备的微粒与上述方法制备的微粒的平均直径和分布相似，只是产量太低，而用机械法制备的微粒平均直径在3μm左右且分布较宽；不同的过程参数对沉析微粒尺寸有不同的影响，预膨胀压力、膨胀室温度、溶解温度以及夹带剂浓度的提高或增大，均可使沉析微粒的直径变小；预膨胀温度提高，所得微粒的直径变大；喷射距离的增加，沉析微粒的直径变小；喷嘴直径越小，由此制得的微粒的直径就越小；根据实验结果还可知道，通过理论计算的马赫盘处微粒的直径可以较好地估计出膨胀室中收集到的微粒的直径。

As an unloader it does essentially the same thing except that when you close the gun the unloader traps the pressure in the hose and locks the unloader open, allowing all the water the pump is pumping to recirculate back to the inlet.

当系统压力超过弹簧张力时，水流从喷嘴回流到泵进口，进行循环。

The higher than predicted maximum pressure could conceivably be a consequence of nozzle slagging .

高于预测，最大的压力，可以想象的后果喷嘴结焦。

Some problems are discussed about high pressure water rotary seal and atomized nozzle property.

分析了电牵引采煤机喷雾除尘效果差的原因，提出了喷雾系统采用高压水射流喷雾除尘，并对系统压力提高后涉及到的旋转密封、喷嘴性能等技术问题进行了讨

The characteristic and the pressure distribution of the impinging jetting in the center of submerged muzzle are studied.

在水射流流场数值模拟的基础上，对淹没中心喷嘴冲击射流流场的特性和压力分布规律进行了研究。

On the other hand,simulate by the Fluent software the jetting status of the double orbits water jet

另外还用Fluent软件分别对双头不同导程的2种旋转喷头在40 MPa进口压力条件下的喷射状态进行分析，从而得出旋转锥形喷嘴的最佳工作状态。

Break or cause a number of reasons for the plug is usually used to place the empty cartridge a longer time to reperfusion ink, the ink nozzles in the absence of a state is easy to plug dry; additional ink when not handled properly, such as internal and external pressures to adjust properly, the phenomenon can also result in disconnection.

造成断线或堵头的原因有几种，通常是用完的空墨盒放置较长时间才灌墨水，喷嘴在无墨的状态下很容易干结堵塞；另外加墨水时处理不当，如内外压力调整不当，也能导致断线现象。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
