内阻力

It shows that the exhaust resistance at the wind blast end reduces obviously, driven by the 800mA/12V small scale draught fan, average exhausting speed reaching above 4m/s, fairly enough to satisfy the air conditioner's demand for new wind volume. Meanwhile, the conic section of the horizontal profile and the linear design of the longitudinal profile of the exhaust end inner cavity and wind shroud for each outlet greatly reduce the flowed out exhaust, effectively lowering the wind blowing feel of the air conditioner user by playing the function of air diffusion.

经过计算和实际测试表明，该装置的送风末端风口阻力明显减小，在800mA/12V小型风机驱动下，出口平均风速可达4m/s以上，足以满足空调对象的新风量要求；同时，横截面采用2次曲线型设计、纵截面采用流线型的送风末端内腔和出口均风罩使气流流出后风速迅速衰减，起到散流器的作用，有效降低了空调对象的吹风感。

增加出水管内的阻力，以减低流量；检查泵吸水管；检查底阀；减低吸水高度；堵塞漏气处；降低液体温度。

The experimental results indicate that, over a ranger of tube side Reynolds number and Prandtl number (Re=4000~20000, Pr=6~7.5), the internal Nusselt number and friction factor of spiral-flat tube increased by 30%-150% and 20%-50% respectively compared with smooth tube at the same Re and Pr. The value of friction factor decreases with increasing the value of B/A as well as increasing that of S/de, and the same phenomena can also be observed for Nusselt number.

实验结果表明：管内Nu和f值均随均随B/A值和S/de值的增大而减小，但随B/A值的增加而减小得更快，B/A值对螺旋扁管管内传热与流阻性能影响更大；在相同Re和Pr下，螺旋扁管管内Nu数为光滑管的1.3～2.5倍；阻力系数f是光滑管的1.2～1.5倍。

The ultrasonographic images of OP could be classified to 3 types: 6 cases of interior ovary, 6 cases of exterior ovary and 9 cases of mix echo of the ovary appendage. The diagnostic incidences were 28.6%, 28.6% and 42.8%, respectively. There were 2 types of diagnostic results of 13 OP cases using TVCDUS before operation, including 9 cases of dot flow signal, 4 cases of half ring signal.

OP术前超声声像图分3型：卵巢内型6例（28.6%），卵巢表面型6例（28.6%）和附件区混合回声型9例（42.8%）。13例OP患者术前包块CDFI检测结果分2型：点状血流信号型9例（69.2%）和半环状血流信号型4例（30.8%），其中5例测阻力指数，平均为0.43±0.12。

The particles with heavy specific gravity are discharged from the underflow mouth and those with light specific gravity are discharged through the overflow pipe and thus it realizes the separation for heavy and light particles.

流体自旋流器上端给入并在旋流器内形成强制旋转流，旋转流将颗粒按粒度和比重分为内外环层，当矿浆流动至锥体部分时，由于锥体的突然变向，阻力增大，颗粒群向下运动的趋势减缓，并在此形成旋转悬浮层，随着离心力场的减弱，重力作用越来越明显，由按粒度和比重分成的内外两层逐渐转化为按比重分选的上下两层，比重大的颗粒通过底流口排出，比重小的颗粒则通过溢流管排出，从而实现轻重颗粒间的分离。

If the trap concentration of condensed water discharged from the recovery, at this time, the export of back-pressure steam trap is the resistance to water pipes, water pipes back to the high elevation, the second evaporator and pressure of the three.

如果把疏水阀排出的冷凝水集中回收，此时，疏水阀的出口背压是回水管的阻力、回水管抬升高度、二次蒸发器内压力三者之和。

如果把疏水阀排出的冷凝水集中收受接管，此时，疏水阀的出口背压是回水管的阻力、回水管抬升高度、二次蒸发器内压力三者之和。

To calculate the pressure drop of cyclone must consider the tangential velocity. Researchers regarded inner vortex as quasi-forced vortex and outer vortex as quasi-free one before.

旋风分离器阻力损失的理论计算离不开切向速度分布，以往在切向速度的研究中，认为内涡旋是准强制涡、外涡旋是准自由涡。

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。
