However, most of the fatigue data which are used for those strength designs are obtained by uniaxial loading tests, and there is limited data under multiaxial loading [2-3].
Those measured data is used for evaluation of fatigue life and feedback to control the test by using inner pressure and axial load.
The correlation for 316SS also shows the same tendency as that for 430SS under the same loading paths, but the reduction in fatigue life in the Square-shape and the LT-shape is much less; one-digit decrease.

The reaction quenching and sampling times were deducted from chronoamperometry (CA) data, as the current signal reflects the changes in reaction type and rate at any given time.
Additionally, during the sputtering process, the oxide layer penetration time can be measured and the layer thickness calculated using calibration data and standard equations.
This finding is also to some extent supported by the CA data.
Summary It was found that all three salts were corrosive, and that the oxidation current reflected the oxidation-reduction reactions, thus revealing a difference in reaction mechanisms and rates between the salts.

ETR was plotted against irradiance, and maximum relative electron transport rate (ETRmax), photosynthetic efficiency (α) were calculated by fitting the RLCs data to an exponential function [4]
Data analysis One-way ANOVA was used to test for site differences in photosynthetic variables (ETRmax, α, Ek).
(ETRmax and PAR data were log10(x)-transformed prior to analysis).
The deep water species positioned in depths over 10 m subject to severe light limitation and lack of reduction in α at midday.

This paper worked on the geological conditions and measured datas of ground surface settlement caused by shield construction at the South Gate of No.2 metro line in Xi'an, the traditional prediction formula of ground surface settlement was fitted with the measured settlement values of the natural ground surface, and proposed a modified prediction formula.
In 1969, Peck collected and analysed the measured data of ground surface settlement caused by a large number of different types of underground construction, and proposed the concept of ground loss, obtained the regression model of a series of the settlement trough’s approximate width related with the stratum, without considering the soil drainage consolidation and creep deformation, namely Peck formula[1].
two-dimensional nonlinear finite element parameters analysis, on this basis, Han Xuan[7] proposed the concept of modified stiffness approach (BGI method), the basic formula is summarized as follows: the foundation’s settlement trough curve of the building with a continuous and uniform structure stiffness can be described with Gaussian curve, namely: (5) V1S represents the ground loss coefficient of the settlement curve of the building’s cross section, it can take the same value with the natural foundation due to it’s mainly affected by the construction and formation conditions, that is the ground loss of natural formation, taken as 0.75%; Ks is the settlement trough width parameter, it can be described as the following formula considering the main factors of foundation depth and building stiffness: (6) K is the settlement trough width coefficient of the natural ground surface, and it can be selected based on experience or observation data
Taking into account the reduction factor ζi of the masonry wall, the core soil of the wall, foundation and door opening, the sectional shear stiffness M is approximate 600 ×109N after calculation, stiffness correction factor = 2.27.
This paper presents a formula combining the existing Peck formula and modified stiffness approach together to predict surface settlement induced by shield tunnelling, and the actual project monitoring datas show that it can be used to estimate the ground surface settlement induced by shield tunnelling of Xi’an subway construction.

Each experiment was repeated three times and the data were averaged.
The deviation from additivity is explained by the increase of the heating efficiency up to 51% (close to the specification of the commercial MW oven) with an increase in the input power due to a shorter contact of the heated substrate with the cold wall of the chamber and, therefore, the reduction of the heat dissipation outside.
Taking into account both the heating efficiencies data and the variation of heating rates, it was calculated that the summing of the energy of three MW generators with the efficiency close to 100% was achieved.
Analytical pyrolysis data have revealed that, at a low temperature, MW processing promotes the transition of secondary phenolic metabolites into solution in comparison with modern accelerated solid extraction (ASE) using conventional heating.

The big different behavior of Co and Mo during the reduction process is believed to be related to the different interaction between them and MgO.
In bimetallic Mo–Co/MgO catalyst, the addition of Mo and the formation of MgMoO4 in the catalyst make the catalyst particle much smaller than Co/MgO catalyst because of the avalanche-like reduction of MgMoO4 during the reduction process.
This result matched with the XRD data where a well defined narrow peak was observed for CNTs grown by catalyst was seen.

The external forces are computed from the image data.
(2) This variation formulation follows a standard principle to make the result smooth when there are no datas.
The obvious reduction in number of iterations and less time consumption are seen from contrasting two figures.
The reverse subdivision scheme produces very dynamic data structures.
