The low frequency noise sdandard The low frequency noise can affect the residents’ auditory comfort.
The Subjective Evaluation The subjective evaluation method of ecological residential area acoustic environment bases on people's subjective evaluation of the different sounds and different responses which combined acoustic environment with many physical properties of the sound.
Including many subjective factors, the subjective evaluation method needs further improvement and perfection.

The temperature and wall thickness of the fiber added affect its formation.
In previous work [8-10], the mechanical and tribological properties have been characterized, and the interfacial characteristics of the Saffil fibers reinforced AE44 magnesium alloy have been investigated already.
Thus, it is very important to choose suitable process parameters if good mechanical property is required.

Introduction Nickel-based superalloys are widely employed in aircraft engines and the hot end components of various types of gas turbines due to their high strength, strong corrosion resistance and excellent thermal fatigue properties and thermal stability [1].
These properties lead to a series of flaws, such as excessive tool wear, frequent tool change, short tool life, low productivity, and large amount of power consumption, etc [2, 5].
Among the most of the major parameters that affect the machining performance, including the choice of cutting tool, machining method and cutting parameters, etc., the cutting tool is the most critical one [6, 7].
In this study, the maximum flank wear at the cutting edge area seems to be the limiting factor that controlled the tool life in all cases.
The whisker reinforced ceramic tools are effective in machining nickel-based alloys not only in the material removal rate, but also in total removal volume due to their good properties, such as chemical stability, high hot hardness and high wear resistance at high temperature.

Well-established mechanical saws are widely used within IC manufacturing.
That is why the traditional process flow for mechanical wafer dicing is compared to the novel TLS technology.
A crack is guided by thermally induced mechanical stress.
This results in optimum optical and electrical properties of the chips produced.
Depending on the drop size considered, drying time was increased by a factor of 2 to 4.

Selection of optimal values of process parameters, such as pulse duration, pulse frequency, duty factor, peak current, dielectric flow rate, wire speed, wire tension, effective wire offset of WEDM process by applying six most popular population-based non-traditional optimization algorithms, i.e. genetic algorithm, particle swarm optimization, sheep flock algorithm, ant colony optimization, artificial bee colony and biogeography-based optimization for single and multi-objective optimization.
Cemented carbide, which is about two times harder than high-speed steel, exhibits superior wear and heat resistance properties [5].
The artificial neural networks are made of inter connecting neurons which may share some properties of biological neurons.

In reality there is always a combination of all three orders of internal stresses but for part properties only first order internal stresses are of interest.
Test material properties are presented in Table 1.
Test material properties.
The best results were obtained by mechanical cutting without grinding or polishing.
In addition to cutting methods, deviation is caused mainly by the fixing position of the sample and material properties.

The final result is that the sinter is not burned through or over burned, which will directly affect the quality and yield [1].

The properties of an Ohmic contact, in turn, depend on several factors, including the metal/semiconductor barrier height, the interfacial roughness, thermally induced solid-state interfacial reactions, material doping, etc.
However, due to the difficulties to grow high quality 3C-SiC, the available literature lacks any report about Ohmic contact properties on single-domain 3C-SiC crystals.
In this work, both nanoscale and macroscale electrical properties of Ni/3C-SiC Ohmic contacts to single-domain 3C layers, heteroepitaxially grown on 6H-SiC by a VLS technique, were studied as a function of annealing temperature.
Transmission Line Model (TLM) patterns were fabricated in order to study the electrical properties of the contact, using optical photolithography and wet etching of the metal.
The changes observed in the contact material are caused by thermal reactions induced by the annealing (as observed by XRD), which change the structural composition of the interface and thereby also affect the morphological and electrical properties of the Ni/3C-SiC system.
