Firstly, the data sources were introduced and the typhoon landing areas are all over the east coast of China were analyzed.Then, development trends of the affected area, deaths, houses collapsed and the direct economic losses were studied in detail.
Typhoon disaster data Typhoon disaster data were from tropic cyclone disaster database provided by China Meteorological Administration (CMA), Ministry of Civil Affairs of China and Disaster Reduction Center of Chinese Academy of Sciences.
These data included 134 typhoons from 1985 to 2006, which were used to establish a typhoon economic vulnerability curve between typhoon intensity grade and direct economic loss.

The appropriate vibrating intensity will increase the contact of SRBd and wastewater ,Increase the speed of sulfate reduction and improve the speed of reaction.
According to the experimental data, the best vibrating intensity is 100r/min.
COD/SO42- play a crucial role in growth of SRB and the removal rate of SO42-, the competition of SRB and methanogens is inevitable in treating AMD containing high concentration sulfate, many experimental results says that if the ratio of carbon and sulfate is large in concentration organic wastewater treatment, Methanogens reaction is main reaction, so the sulfate reduction is inhibited.
With the data of this experiment, the optimum carbon-sulfur ratio is 2:1.

Its effects on reinforced concrete structures include reduction of bond between concrete and corroded reinforcement, reduction of cross-sectional area of reinforcing steel [1-2].
Due to lack of sufficient experimental data on the effect of corrosion on the bond stiffness, only the influence of corrosion on the bond strength is taken into account in this paper.
The dimensions and reinforcements of lock-wall are shown in Fig. 3 and more detailed data are described in [9].

Although using formaldehyde is a risk to human health, recent data demonstrated that formaldehyde fuel cells are attractive alternatives for proton exchange membrane (PEM) fuel cells applications [1-3].
The experimental data reveal that the modified electrode has a very high catalytic activity for formaldehyde.
As it can be seen, whereas neither oxidation nor reduction took place on P(OT)/GCE a well defined stable redox peaks were observed for Ni-P(OT)-PVA/GCE in the potential ranges from 0.2 to 0.8 V vs.
This phenomenon was attributed to the oxidation of Ni(II) to Ni(III) with a peak potential of 0.61 V and to the reduction of Ni(III) to Ni(II) with a peak potential of 0.45 V vs SCE.

Introduction The presence of crack in structure usually causes a local reduction in stiffness, and an increase in damping, and a reduction in natural frequencies, and thus results in a change in vibration characteristic of structures.
The ease of experimentation and data processing of vibration based detection methods make them attractive from an engineering perspective.
For the prediction of crack details from these data, a program has been written in MATLAB based on the theory given earlier.

Aims of the additions, among others, are reduction of impact of silicon on coating growth, reduction of zinc loss, increased bath liquidity and improved corrosion resistance of coatings.
Comparison of the data recorded during static tensile test for the sample of C70D steel Sample Displacement [mm] Maximum extension [mm] Maximum load [kN] Stress at max. load [MPa] Maximum modulus (Young) [MPa] Strain [%] C70D 3.810 4.625 10.87 1765.0 56920 9.25 The study was carried out in metallization bath prepared using tin of 99.99 % purity.
The test setup consisted of two modules: a heating furnace PET 22/45 with the temperature registration and control system and the module for induction of external stress in the sample equipped with the weight transmitter and terminal for continuous data registration.

., the LTE-Advanced system, employ spectrum efficient modulation scheme and carrier aggregation techniques to enhance the data transmission rate and enlarge the network capacity.
The PCB and the devices such as transistors and power splitter are solder on the heat sink for better thermal conductivity and reduction of memory effects.
Five carriers 64-QAM modulated LTE-A signals with totally 100MHz bandwidth are generated in the personal computer (PC) and the PAPR is reduced to 6.8dB after crest factor reduction (CFR).
Inverse PA modeling is carried out in the PC with the I/Q data acquired in the N9030A.

Introduction Calculating Losses line loss is to develop assessment criteria based on energy-saving and loss reduction program, which provides technical information for the distribution network planning, renovation and capacitance compensation and voltage regulation, and economic operation.
Due to low voltage distribution network (380V) complex, a large number of single-phase loads, loads of different shapes and load curve together, it is a three-phase unbalanced operation of the main features of low voltage distribution network, so the three-phase asymmetric operation are the main characteristics of low-voltage distribution network, in addition to low-voltage distribution network meter Configuration incomplete, difficult to collect detailed operating data, especially the first end of the three-phase current line is difficult to obtain, therefore accurate calculation theory of low- voltage distribution network line loss is very difficult.
Using the method of literature [3] in the case of 2-10 (asymmetric three-phase load) was calculated, the three phase current 34.39 A, 28.35 A and 22.3 A respectively with examples given in the data, this method is proved to obtain three phase current, average current) is effective and practical.
Rural power line loss analysis and calculation of loss reduction measures [M] (second edition).

Changing the driving style is one of the most effective ways to achieve energy savings and emission reductions.
In consequence, study of energy and emission reduction technology based on driving behavior has great potentials.
Data Analysis and Results Let B denotes the general driving and N denotes the driving with eco-driving support.
From the measured data, average speed on the urban road and on the motorway in the two driving behavior are shown in Figure 1.

It can be seen that the data matches very well.
Comparison of CFD simulation and analytical data for an empty channel Results and discussion In this section, the influence of spacers for fluid flow was verified.
Spacer of new shape gives significant reduction in pressure drop meanwhile the shear stress maintains a comparable value.
The CFD simulation also indicates that spacer of new shape gives significant reduction in pressure drop while the shear stress retains a comparable value.
