To maintain a low-stress condition, small feed should be taken, so the reduction in the fatigue strength can be prevented.
Experiment should be performed in future in order to acquire the data as a reference of simulation.

Now the sludge disposal methods are: incineration, landfill and two times using etc..But these kinds of sludge treatment methods have more or less defects, can not achieve the sludge reduction, harmless and resource processing purpose.However, city sewage sludge shale brick research and extension can be a good solution to this problem.
Effect of sintering temperature on the phase of sludge sintered shale fracture Experimental comparison with the sintering procedure two different, table 2 is through the sintering experiment and processing a large amount of data, to obtain sintering process for sludge sintered shale brick.Will the rest of adobe into C, D two group (Note: two groups of brick are drying procedures reasonable drying Adobe).Group C bricks used are shown in table 2 sintering procedures fired, group D adobe shown in table 3 sintering process in fire.Every 60min observation time, record the number of the crack in the brick.
Target temperature Heating time /℃ /min 1 Initial temperature — 2 100 20 3 200 20 4 300 20 5 400 20 6 500 20 7 600 60 8 700 60 9 800 60 10 900 60 11 1000 60 12 1000 800 Based on the data analysis, the finished brick sintering D experiments, the number of crack growth in each stage is much more than the same period in C group.Because the dried brick sintered in a sintering furnace, there are two kinds of water brick, a water residue after drying, another is the combination of water in organic compounds[3]。

In order to ensure the desulfurization units operated continuously and efficiently, a series of policies and measures such as desulfurization electricity price subsidy, dispatch by energy-saving and emission reduction had been carried out by the State.
Nowadays, for some of the Chinese desulfurization units, part of the gas parameters such as chlorine, fluorine and dust in flue gas were designed almost the same, and the commonly used design data were: HCl ≤80 mg / m3, HF ≤ 25 mg / m3, dust ≤ 100 mg / m3 (the data were in standard, dryer and excess air ratio 1.4).

Integration of the surface pressures leads to the time series data of base moment coefficient, of which the amplitude and frequency-domain characteristics were studied and compared with those of the single-tower.
Wind tunnel test and model summary The wind tunnel test with simultaneous surface pressure measurement was carried out in TJ-2 atmospheric boundary layer wind tunnel in the state key laboratory for disaster reduction in civil engineering in Tongji University.
Fig. 5 Frequency-domain characteristics of the base moment of interfered tower in 0o wind direction Summaries In this paper, a wind tunnel test with simultaneous surface pressure measurement was carried out and the relevant data analysis was done.

Therefore, reduction of the network delay and jitter has always been the improved direction which the network equipment suppliers care for.
The MPLS network is in the middle of data link layer and network layer, belonging to the 2.5 layer protocol.[1] In an MPLS network the label switched path (LSP) is established for the message through the pre-assigned label.
It can provide nanosecond-level synchronization precision in a geographically dispersed network, therefore it is available to transmit all kinds of real-time services and data services for the network.[2,3] Fig. 1 Forwarding process of MPLS The IEEE 1588 standard defines 4 kinds of synchronous messages, including Sync, Follow_up, Delay_Req, and Delay_Resp.

Some methods have been investigated including reduction the particle size to nano scale and making porous nano TiO2.
Powder surface area was determined from N2 gas-adsorption data using Brunauer–Emmett–Teller technique (BET) with Belsorb II.
The average crystallite size of the synthesized samples was calculated from the XRD data according to the Scherrer's equation [11]: [1] where d is the crystallite size, k is a constant (0.9), λ is the wave-length of X-ray (CuKα), β is the half-peak width in radians and θ is the Bragg's diffraction angle in degree.

According to statistic data, the rate of wedging or hitting bridge about large trucks stays at a high level [2].
The optical signal modulation circuit is shown in Fig.2. 1.2 Design of the Optical Signal Demodulation Circuit For receiving circuits, the SCM of receiving signal is used to process the received data.
Judging the rising-edge and falling-edge can enable and turn off the timer, next calculates the pulse width, and then comparing it with the reduction of the pulse width (preset value) can calculate the number of sensors being obscured, according to the number, the height of the vehicle can be calculated precisely .The algorithm is only suitable for measuring objects without hollow.
