They are: efficient request distribution, fine-grain load balancing, effective memory utilization, optimized processing of popular objects, and minimal network resource consumption in coordinating the web server nodes.
This is especially important to the dispatcher approach because the overhead in the Dispatcher limits the maximum number of requests that the cluster can accept.
The following are load metrics widely used: the number of tasks in the target running queue, target response time, the percentage of free memory, the percentage of free CPU time, the shifting rate of CPU contest, the average load in one minute, etc.
We use RSC but not commonly used current task number (current linking number), because the capability of each web server varies greatly, and thus current task number cannot reflect the real load capability of the system accurately, and the efficiency of processing various tasks would be more diverse with the different ways of HTTP request combination.

In the 21st Century, the increasing economic globalization, technological revolution, and economic restructuring not only makes great changes to the production and living styles of people, but also causes a number of social and environmental issues, even deterioration of the ecological environment.

Research results about Qinling-Dabie collision belt shown that it finally completed collision and piece together in the late Jurassic, marginal residual sea in collision belt and both sides appeared completely, a large number of age data of syn-collision period metamorphism and magmatism were averagely 240～210Ma[21～25], which shown that the piece together completed in the late Jurassic.
The 210～200Ma was of post-orogenic stretching stage, combination of Chashan post-orogenic high alkali sinaite formed, for spotted medium-fine grained syenogranite in rock mass of Geji, SHRIMP U-Pb age of zircon was 205.7±1.4 Ma, 211.9±1.5 Ma[26], which represented the end of Indochina orogenic stage, meanwhile proved that piece together of south and north plates had finished in the late Triassic.
The general trend of magmatic evolution from early to late is that plagioclase and potash feldspar have relationship of growth and decline in mineral composition, content of SiO2 is decrease progressively as a whole in chemical composition, and that K2O+Na2O is increase progressively, change of rock texture as follow: fine grain—medium-fine grain—medium grain—medium-coarse grain—pegmatoidal texture.
This granite contains a great quantity of fine grain dioritic inclusions, in which there are not only have obvious magmatic texture but also have spotted acid granitic composition that have the same property with country rock and potash feldspar phenocrys.
Concerning to the age of lithospheric thinning, large numbers of researchers restrict time limit of structural system transition and lithospheric thinning in Mesozoic from different point of view.

In the present study, uniaxial tensile test of aluminum alloy casting containing defects was simulated and analysed, and the effect of types and number of defects on mechanical properties was studied by finite element analysis software.
The number of pores and oxides is in equal portion in the defects d) In order to study the influence of different defects in shape to mechanics properties of aluminum alloy castings, this paper use circular, square and rectangular approximate to simulate the casting defect and establish aluminum alloy casting uniaxial tensile test finite element model under the conditions of the defect rate in 3% based on the statistical results.
Although the number of pores is less than that of oxides based on the simulation results, just as oxides, pores could be observed in Aluminum ally castings with degassing or not.
The oxidation inclusion's increases improve the tensile strength of casting in some way, when the number of pores and oxides is in equal portion in the defects, along with the increase of the defect, the tensile strength of casting increases slightly.

The number of survival bacteria after treatment was evaluated with spread plate techniques.
The number of survival bacteria after treatment was evaluated with the spread plate technique.
After colonies are grown, they are counted and the number of bacteria in the original sample is calculated.
The number of viable bacteria was determined by using the spread plate technique after passing through reactor of each cycle.
The survival rating of E. coli was determined by counting the number of viable cells in terms of CFU.

In the finite deformation range, the numbers of orthotropic 2n order elastic constants are studied on the basis of tensor function and of its representation theorem.
Through the study of symmetry, we can deduce the number of independent components of the 2n order of the orthotropic materials.
The number of the 2n-order elastic tensor of orthotropic materials can be derived with symmetry study.
The formulation of independent component numbers of the orthotropic elastic tensor is: (6) When using the short way, the tensor independent component can be expressed: 4 order (n=2) There are 9 independent components of the orthotropic elastic tensor: 6 order (n=3) There are 20 independent components of the orthotropic elastic tensor: 8 order (n=4) There are 42 independent components of the orthotropic elastic tensor: Thermal Elastic Constitutive Equations of Orthotropic Materials Lemma 2.1 E is symmetric.
For specific orthotropic materials, minimum numbers of elastic constants should be adopted in experimental observation

When a cyclic loading of 1µN.µm was exerted to the micromachining flexure hinge, the limit stress alternation number exceed 1.0×10 8.
When the stress alternation number exceeded 1.0×10 9, the polysilicon beam of microactuator would lost its elastic character.
In addition, the micro grain cannot be produced because there is no wear.
When cyclic loading of 1µN.µm was exerted to the thin film flexure hinge, the limit stress alternation number exceed 1.0×10 8.
When the stress alternation number exceeded 1.0×10 9, the polysilicon beam of the microactuator lost its elastic character as shown in Figure 9.

The effective atomic number Zeff (see Table 1) is an indication of the material’s energy response.
The crystalline material was crushed and sieved to select phosphor powder with grain sizes between 100 and 300 µm.
Finally, the polycrystalline phosphor was crushed and sieved in the grain sizes between 75 and 200 mm.
For preparing pellets, phosphor grains in the range 75 and 200 µm, were compacted into pellets of dia. 4 mm.
Applications of RPL glass dosimeters have been highlighted in a number of publications [216, 217].

In the macroscopic view, the surface morphology of coating is shiny white, its colour and lustre is uniform and continuous; in the microcosmic view, coatings are compact and flat with small crystalline grains instead of many holes made by micro-arc discharge, because the silver layer has completely covered the MAO coatings which can seal the holes produced by micro-arc oxidation.
The concentration of reducing agent was certain, as the reaction processing, the number of Ag+ which can be deoxidated was decreased when the concentration of AgNO3 was larger than 5 g/L.

In tamping test, nine tamping points will be recorded, and the tamping times needed in every area is ascertained by the times at which the settlement in last two tamping is not more than 5cm; 3) Loose layer will be formed on the surface in full tamping for the stress diffusion,which can accelerate the local consolidation, every parameters can be decided by trial tamping; 4) The growth and dissipation of pore water pressure in saturated sand is very short, but it also needs to leave a certain interval time, at least two days after local tamping, to ensure the pore water pressure dissipate gradually in the form of changed grain flow.

Heavy dynamic penetration test point quantity are not clearly defined, but it should correspond to the number of loading test in rough, so as to observe the change of bearing capacity and density of foundation versus depth.
In the course of penetration, record the number of tamping at a certain depth, on which to determine the bearing capacity of the layer.
