The twoparameter
Weibull statistics was applied to the ranked cumulative probabilities of the maximum
flexural stress data [5].
That led to reduction of the thermal conductivity by about 35% of value and increase of CTE by 20% after 1000 cycles, whereas a stronger bonding between the reinforcement and matrix resulted in reduction of the thermal conductivity by 10% upon thermal cycling.

The paper collects plenty of socio-economic and hydrological data of the Weihe River basin and establishes numerical models for comprehensive simulation of socio-economic system and water resources system, including CGE model, ROWAS model and WEP model.
It’s indicated that, based on analysis of results by CGE model, water consumption structure adjustment of transferring water consumption from agriculture to industry and services may promote economic growth and social progress with the increase of GDP, rural income and expense, urban income and expense, and reduction of total labor surplus rate.
The surface water supply decreases as a result of reduction of agriculture water consumption mainly because of its low cost in process of exploiting surface water resources.

This reduction of Tg caused by the plastizing effect of ionic liquid which disrupts the semi-crystallinity structure of PEO making it more amorphous [8, 9].
The reduction of Tm suggests that the interaction between the polymer host backbone and NaCF3SO3 affects the main chain dynamics of the polymer.

For example, platinum/poly(4-methyl-1-pentene) (PMP) composites [4] have been obtained
by impregnation and reduction of CODPtMe2 in presence or not of CO2 and H2.
For a comparison with literature data, CO2 mass sorption incorporated into polymer matrix is given by Eq. 5 where ρpol is the polymer density.
We have confirmed the reduction of PEG viscosity under scCO2 conditions.

For pure mode II where B is about 1.6 a reduction in mode II fracture
toughness is expected to take place.
A similar reduction in mode II fracture toughness due to positive T-stress has been observed in experimental results obtained from fracture test on the semicircular bend specimen [11].

Numerous precious data on surface
integrity, including surface roughness, microhardness, plastic deformation and residual stress when
machining Inconel 718 have been published.
According to Ezugwu et al. [3], increasing the cutting speed also attributed to the reduction of the friction coefficients, which resulted in low friction at the tool-workpiece interface.
This enables the reduction of friction and heat between the tool-workpiece interface [5].

The tolerance allocation is determined also using the cost versus tolerance data available using optimization techniques [3, 4], considering the demands of manufacturing cost and product quality [5] are developed approaches based on the Shapley Value Method (SVM) of coalitional game theory but equally in [6] it is presented a tolerance allocation approach based on a tolerance allocation strategy that uses time as the basis for optimization, strategy suitable for use in a Concurrent Engineering (CE) framework.
Inverse of this ratio is the coefficient for proportional reduction P of components tolerance, anterior finding (row 34).
This entire tolerance ratio was multiplied with coefficient for proportional reduction P (row 37).

Introduction
Starch-cadmium iodide methods used for oilfield sewage of polyacrylamide (HPAM) mass concentration analysis by SCOGGINS M W et al [1]for the first time,research indicates that adjustment buffer pH to 3.5 can eliminate interference a great quantity of Cl- in the sampe,in the buffer to add too much Al3+ can eliminate interference from Fe3+ and Bi3+ etc high cation.Junming Hu et al[2]choose the stable performance good soluble starch,iodine starch complex have the strongest absorption in the 590 nm place.The results showed that pH is between 3.7 and 4.5 absorbance changes smaller buffer pH adjustment to 4.0 advisable.Shiguang Yang et al[3]with NH4HF4-FeSO4 system instead of sodium formate also concentrate,measuring absorbance in the 420nm place,the method of measuring range from 0~6 mg/L expanded to 0~24 mg/L,and eliminate the absorbance with reduction reaction time increased and falling phenomenon。
Table2 The relationship between bromine water quantity and absorbance bromine water quantity/mL ρ(HPAM) ∕ (mg/L) 10 20 30 40 50 2 0.106 0.187 0.295 0.396 0.479 3 0.111 0.185 0.290 0.393 0.469 2.1.6 The dosage of sodium formate to the influence of the reaction system The experimental process found to join 5ml sodium formate after solution color not change, measuring its absorbance to zero, so that the 5ml sodium formate enough to make too much bromine reduction。
Then known by test data that ρ(HPAM)4.5 mg/L,5.0 mg/L,100.0 mg/L in the curve,and ρ(HPAM)4.0 mg/L ot of the curve.Starch-cadmium iodide method measuring the quality of HPAM concentration lower limie is 4.5mg/L and upper limit is 100.0 mg/L。

The initial reduction of the creep compliance is predominantly caused by the reinforcement of the polymer through the nanotubes, so-called chain immobilization due to formation of a significant inter-phase zone of altered polymer mobility surrounding each nanotube [22, 23].
Good nanotube/matrix interfacial bonding provides further creep reduction through frustrated chain disentanglement, stretching and fragmentation of the macromolecule.
