Inset; Raw spectra for Bi2201 with two different x values, this data was taken using a 600lines/mm grating.

After 3 months’ measuring by precision level,the data shows that the maximum point is in the center line of the tunnel of the upper part.
(2) Analysis (2) know, whenor,, the scope of the impact of the actual surface that tunnel excavation, according to the monitoring results, tunnel excavation scope of influence for 21 m, when x=0, P(x,y)maximum value, that it is at the top of the tunnel center, according to the measured results for - 31.82 mm, It can be concluded that，, draw winkler calculation model prediction equation: (3) The Winkler model subsidence data calculated by the formula (3), as listed in Table 1.
Table 1 Winkler model settlement data and 04 section measured data Field test results and the ground surface settlement calculation model winkle are identical with each other, winkler calculated value is smaller than the actual observations, only practical writing Kerr surface subsidence prediction model can draw the trend of surface subsidence, it can't accurately draw maximum settlement. this is because the soil above the tunnel in the actual engineering fill is the artificial hormone and have a small amount of construction waste, theory and assumes that there is a certain gap; At the same time in the theoretical calculation without considering bellows-liquid coupling condition soils and the distortion of the structure is in compliance with linear elastic properties.
Fig.4 The field measured and winkler model calculation curve contrast 5 Conclusions (1)Dalian subway 202 section (Cujin Road station-Chunguang Street station) introduce distance span ratio β in the surface subsidence in the process of data analysis, surface subsidence maximum position just above the centerline of the tunnel, the settlement is about 25.66 ~31.82 mm.
With the working face advancing, the longitudinal settlement along the tunnel is divided into three stages, -4<β<-2 surface subsidence acceleration phase, occupy whole deformation10.8-16.6 %; -2<β<2 the surface subsidence violent stage, occupy whole deformation67.5-77.6 %, settlement rate can reach about 0.84 -0.96mm/d; 2<β<4, the ground surface settlement reduction stage, settlement change tends to be stable.

Introduction In the manufacturing of dies and molds, the need for high-speed machining technology that can provide the advantages of high-quality machined surface as well as the reduction of machining time and lead time is ever increasing.
In this approach, the machining conditions { N , tf , rd , ad } at each stage, which have been evolved with the ones selected at random as initial conditions, are used as the input data for the ANN.
Table 4 shows 10 selected data nearest to the required conditions obtained from the simple search results for all possible cases in order to find the machining condition in which the MRR is greater than the desired MRR and the surface roughness is the lowest.
It is expected that the accuracy of the search for the optimized machining conditions can be increased and the optimum solution for the multi-objective function can be obtained by securing more data and by using detailed restricted conditions.
