The only types of humidifiers that can potentially release white dust are ultrasonic humidifiers and cool mist impeller humidifiers.

唯一的加湿器类型有可能释放白色的灰尘，超声波加湿器和冷雾叶轮加湿器。

After the axial profile curves of back shroud are determined, the iterative formulae for calculating the curves of front shroud of impeller are derived in such a way that the flow passage area of the impeller profile varies with the middle curve of passage L linearly.

在确定叶轮后盖板的轴面流道曲线后，从过流断面积F沿流道中线L线性变化出发，推导出前盖板曲线的离散迭代公式。

This pump impeller blades can be adjusted automatically to adapt to speed, fluid viscosity and pressure.

这种泵的叶轮叶片可以自动调节来适应转速、流体粘度和不同压力。

They can be widely used in the following industries:aviation. Aerospace, soldierwork, railroad, metallurgy, the automobile manu_facturing,I.C. engine,shipbuilding ect,especially used for theaccessory made of the magnetic material, such as axletree, shafts of different sizes,pole,crank, impeller,lamina,anchor man chain gear,standard pieces and valve ect,Asto the crack,pucker,loosing such surtace defects caused by the reason of raw materials or heat treatment ,sealing,founding,forging and pressing, tiredness, quenching, milling and paring, our products can detect them without any loss.

产品广泛应用于航空、航天、军工、铁路、冶金、汽车制造、内燃机、造船业、弹簧、压力容器、石化、桥梁、油田、机械制造等行业，如锻压件、轴承、大小轴类、连杆、曲轴，叶轮，叶片，锚链、齿轮、标准件、阀门等铁磁性材料制成的零件，因原材料的原因或者热处理、焊接、铸造、锻压、疲劳、淬火、磨削而引起的裂纹、夹渣、折叠、疏松等表面缺陷的无损检测。

The theory of flow field diagnosis with its computational method has become a new branch of aerothermodynamics in turbomachinery.

同时流场诊断的思想和方法形成了完整实用的体系，为流场诊断学成为叶轮机械气动热力学新的分支打下坚实的基础。

So in this paper, the micro-turbofan engine, which has several ten kilogram thrust level, moderate difficulty, low pressure ratio and single rotor, is studied in three ways which contain overall aerodynamics arrangement analysis and structure feasibility research, optimizing of aerothermodynamics circulation, overall aerodynamics design ane flying performance simulation.

本文对于数十公斤推力量级的、工程技术难度适中的、低增压比的一种单叶轮微型涡扇发动机，进行了总体气动布局分析和结构可行性研究，热力循环优化设计，总体气动设计及飞行特性模拟这三个方面的研究。
