When temperature changes, the material thermal effect, optical lens curvature, thickness and spacing will be changed, and at the same time lens refractive index also produces bigger change[1], which cause the system to perform dramatically.
The defocusing amount of infrared optical system will change when environmental temperature changes, which is shown in Table 1.

Abstract: Rural migrant workers and urban local low skilled labors are in the urban labor market at the same time.
Based on 519 survey questionnaires in Shenyang City in China, the differences of two groups are compared in the industry. 2 Data description 2.1 Investigation and sample selection In this article, Rural migrant workers are defined as agricultural census register, who have rural contracted land, but mainly engage in non-agricultural industries in the city, aged from 16 to 60, as yet unaccepted higher education. urban local low skilled labors are based on method abroad, [1], [2] They are defined as the local employment of non-agricultural registration, aged from16 to 60 and lower education.
Table 1 Employment industry distribution and hour wage of the rural migrant workers and urban local low skilled labors Industry Rural migrant workers Urban local low skilled labors Frequency Percentage Frequency Percentage The First Industry 90 33.21% 26 10.57% The Second Industry 31 11.44% 61 24.80% The Third Industry 52 19.19% 41 16.67% The Fourth Industry 52 19.2% 56 22.76% The Fifth Indsutry 46 16.97% 62 25.20% Total 271 100% 246 100% Table 1 shows us obvious differences of employment industry and wages between rural migrant workers and urban local low skilled labors.

Fig.1
depicts the structure of the system.
Because the cutting depth was defined in the initial selecting module of machining data, there are only two independent variables in Eq. 1, f and νc.
Next, f and νc in Eq. 1 and 2 can be divided into a series of discrete values in term of a certain step, which are substituted into Eq. 3 by means of the grid optimization algorithm.

Through oxidation, hydrolysis, or other chemical reactions are taken place in the wastewater phase[1-4].
Similar experiments are carried out by varying the pH of solution (pH 1-13), dye concentration (1-10 mg/L), catalyst amount (1-5 films/250mL).
From the Fig. 1, the results show that the photocatalytic degradation efficiency of methylene blue increases with increasing the amount of nanometer TiO2 film.

The principle of d-q transform harmonic detection method
d-q coordinate transformation method is simplified on the basic theory of d-q-0 transformation, which is the three-phase voltage ABC coordinates to d-q-0 coordinates through
park transform, which is conducive to extract the fundamental voltage or nth harmonics positive sequence component, Assuming the three-phase input supply voltage including in positive, negative and zero sequence harmonic component, wherein, the zero sequence components value is 0 after Park transform, no effect on the results, so this will not be considered, Assuming that the load voltage contain harmonics component, its expression is:
(1)
In the formula,,were respectively positive sequence current effective value and the initial phase angle, ,were respectively negative sequence current effective value and the initial phase angle, was phase frequency, the subscript "1"and"2" respectively indicates positive sequence and negative sequence
By d-q-0 transform ,the formula (1) can be obtained: (2) From equation (2),it can be found that the nth positive sequence component transformed into (n-m)th 0-d-q coordinates through 0-d-q transform; the nth negative sequence component transformed into (n+m)th component under 0-d-q coordinate system.
