Relieving welding residual stress by applying vibratory weld conditioning Zhengqiang Zhu 1,a , Ligong Chen 1,c ,Delin Rao 1,b 1 Inst. of Welding, Shanghai Jiaotong Univ., Shanghai 200030, China a Zhuzhq01@sjtu.edu.cn, blgchen@ sjtu.edu.cn, craode@sjtu.edu.cn Key words: welding residual stress, vibratory weld conditioning, hole-drilling method, vibratory stress relief Abstract.
Its residual stress level maybe lower than 1/2 yield stress.
We can get following conclusions: (1) VCW can form low residual stress weld joint and its residual stress level maybe lower than 1/2 yield stress
(3) After finishing welding continuing vibrating a period to increase the inputting energy is benefit to the relief of welding residual stress. 6 8 1 0 1 2 1 4 1 6 0 20 40 60 80 1 00 1 20 1 40 1 60 1 80 2 00 2 20 t he max mai n r es i dual s t r es s （ MPa） W me a s u r i n g p o i n t s f i t t l i n e a r Fig..7 relationship between vibratory inputting energy and the maximal main residual Materials Science Forum Vols. 490-491 479 References: [1] B.E.Paton: Electroslag Welding, American Welding Scoity, New York, 1962

The photocatalytic reaction order and the rate constant on these TiO2 specimen for irradiation of 1 h can be calculated using Eq. 1.
Reaction rate [molL -1s-1] = -d[A]/dt = k[A]x , (1) where [A] is the concentration of reactant, x is the reaction order, and k is the rate constant.

For every link ( vi, vj )A’; tlij is equal to clij with probability p and equal to clij with probability (1-p ).
The heuristics for the VRP with a hard time-window consist of the following steps: Step 1.
In this study, the factors determining whether the closest customer can be added to the route included the demand of formers (i + 1),g ( i +1), travel costs from formers i to formers ( i + 1),s i( i +1), time duration between finishing serving formers i to arrival at formers (i + 1), ∆y i ( i +1), and duration from the end of the time-window of formers ( i + 1) to the earliest service time for formers (i + 1),bi( i +1).

The questionnaire used in this research combines the scales of Nick Yee [1], Kimberly Young [3] and Xue Qiang [4].
Figure 1 shows that Female players were significantly older than male players.
Yee [1] stated the motivation factors of playing MMORPGs in 3 categories: The achievement component, the sociability component, and the immersion component (see Table 1 and 2).

R2X=0.691, Q2=0.41.The scatter plot was shown in the Fig.1.
In the scatter plot, there were three observations(C-1, C-2 and D7-1) out of the eclipse.
So C-1, C-2 and D7-1 were outliers.

Introduction Wool fiber is a kind of protein fibers and is popular with people due to its biocompatibility and excellent performance in clothes [1].
While there a little groove on the surface ,the edge of scales was not sharp at all ,and at some place ,there was a certain space under scales ,but it was not very serious .Compared with (b), there were obvious grooves on the scales surface ,the edge of scales were blunt .there was a greater space under scales Effects on Component (FTIR-ATR) From infrared spectrums, it can be observed that there are several absorption peak.1020cm-1 and 1190 cm-1 represent the asymmetrical stretching vibration of cysteamine sulfonate, 1039 cm-1and 1170 cm-1 represent the vibration absorption peak of sulfo-alanine. 1060 cm-1and 1075 cm-1 represent vibration absorption peak of cystine monoxide, 1124 cm-1 represent the vibration absorption peak of cystine dioxide.
From the infrared spectrum comparison among wool without any treatment, wool treated by PMS and wool treated by ozone, there would be a absorption peak at 1020cm-1 and 1039 cm-1,which domesticated that there were sulfo-alanine produced during oxidation process .There is a absorption peak at 1078 cm-1 in wool treated by PMS while not in wool treated by ozone ,which tell that ozone oxide the cystine monoxide and dioxide to cystine monoxide, which can be proofed by the strong absorption peak at 1172 cm-1and 1191 cm-1.

M.Wismans[1] discuss various head injury criteria based on translational accelerations of the head’s centre of gravity and injury criterion based on stress and strains inside the brain.
The criterion used while testing of the helmet is Maximum acceleration induced at the centre of gravity of head form should be less than 275g when helmet is dropped with velocity of 7.1 m/s [4] which is the requirement based on Wayne status tolerance curve as shown in Fig.2 [1] Fig. 2 Wayne state tolerance curve Table 1.
