The number and size of triangles are decided by facet deviation or chordal error [3] as shown in figure 2.These STL files are checked for defects like flip triangles, missing facets, overlapping facets, dangling edges or faces etc. and are repaired if found faulty.Defect free STL files are used as an input to various slicing softwares.
The laser is modulated in such away that only those grains, which are in direct contact with the beam, are affected [10].

Expressions to calculate the characteristics of the RTD curves for slag injections [1,11] Name Parameter Expression Dimensional RTD curve (h-1) E(t) (1) Mean residence time (h) μm (2) Variance in (h2) σ2 (3) Reduced variance σθ2 σ2/μm2 (4) Dimensionless RTD curve E(θ) μm•E(t) (5) Reduced mean residence time μ(m,θ) μm/τ (6) Figure 1 – E(t) curves in time Calculation of the Longitudinal Dispersion and Dead Volumes Ratio: The intensity of dispersion and the dead volume ratio may be known though the estimation of the number of tanks (N) in series of equal volume (V) and equally mixed and the active volume ratio (m), characteristics parameters of the MTS model, using curve-fitting techniques such as the nonlinear least-squares optimization method (LSOM).
These areas lead the appearance of mechanical dispersion phenomena where concentration gradients were developed during the flux of the tracer impulse, with the consequent transport of NaCl molecules into its interior and even into the grain’s porosity.

From 1931 to 1944, the number of factories built with Japanese investment jumped to 323.
(5) The structure with special form, such as the air tank, grain bin, cooling tower can be transformed into amusement facilities in park (see Fig. 4) and city landmarks.

Wu et al.[12] established a groundwater movement equation considering water expansion, aquifer compressibility and solid grain movement due to groundwater pressure decline according to the mechanism analysis of land subsidence caused by pumping, and proposed several measures to control the ground surface settlement around a pit.
Measures to Prevent and Treat the Land Subsidence To reduce the occurrence and speed of urban land subsidence, which endangers the safety of the city and causes huge economic loss, a number of measures have been taken.

The firefighters may use TIC for field operations ranging from the fire attack, search/rescue, hot spot detection, overhaul activities and the location of hazardaous materials [5]. [7] applied thermal imaging in food safety and quality assessment such as temperature validation, bruise and foreign body detection and grain quality evaluation

To record the spectra, each sample was mixed with KBr and ground in to a fine product and examined in the wave number ranging from 400-4000 cm−1.
On the substitution of Pr3+ ions, it is interesting to note that the grain size of the crystals are refined and exhibit finer crystals than the parent compound.

The inner zone of the α-Mg matrix grains remains unchanged, whilst the outer portions are diluted.
Due to the fact that each indentation has a known number, an estimated hardness average for each existing phase can be calculated.

Using the theorem of Vaschy-Bucking ham [2] in formula (1), the non-dimensional formula can be got as: (2) Where , , are the relative values to the width of pier as scour depth, approaching flow depth and sediment diameter respectively, is the influence coefficient of bed composition, is the approaching Froude number. (), , , are all non-dimensional index.
It can be described as : (6) Regarding the wide and shallow river, unit discharge, then (6) can be shown as: (7) where : is local scour depth of pier ; , for the loose sediment with media diameter d50=7.25~14.4mm,=8.6967, a*=-0.0097,=0.0357; should be get from the flow depth after common scouring; has something with pier’s shape dimension and approach flow depth; has a relation with pier’s shape; These all can be looked up in the relevant manual[2] ; select the media diameter d50 of bed sand , unit :mm; From analyzing the obverse data[5,7], =2.63,,=13.69; is control slope, is unit discharge, is gravity acceleration; Except diameter of bed grain, the rest physical unit all adopt m ,s.

According the piston’s anti-fatigue life, an allowable number start/stop count can be defined.
Moreover, crack extension rate can be decreased by using the process of grain refinement.

As Jiangnan political and economic center, Suzhou was the destination for ancient emperor’s cruise, officials and gentries’ official travel and scholars’ travel; Suzhou was also the water transport for grain and salt to the capital and the transportation corridor for civilian production and commercial activities; for a long time, shipping function is the most important and most leading function of the Canal.
During the reign of the Emperor Qianlong, Suzhou painter Xu Yang drew a “Suzhou Prosperous Picture” in which various people jostled each other in a crowd, various ships shuttled, various industrial stores stand in great numbers, showing us a grand occasion of business prosperity and marketplace prosperity of Suzhou.
