Reduction of the emitters’ working hydraulic pressure, however, will directly affect emitters’ hydraulic characteristics and anti-clogging property.
According to the calculated data in table 2, we produced eight kinds of emitter’s irrigation uniformity change curves as shown in Fig.2 under six groups working hydraulic pressures of 1, 2, 3, 4, 5 and 10mH2O.

The hot air recirculation is the main factor responsible for the reduction of heat rejection rate.
The effects of different fan inlet sections on the fan performance are experimentally or numerically investigated and some valuable data were obtained for optimal fan performance by some researchers (Salta and Kroger [6], Duvenhage et al. [7] and Meyer [8]).

The purpose of this paper is to demonstrate a productivity improvement through waste reduction and line balancing.
Based on the data collected from the company, yearly demand is around 1,479,915 boxes with yearly working time of 2,706 hours.

The bigger the reduction of the vehicle weight is, which can be obtain using these alloys, the bigger the energy saving will be in the near future.
Before any test, the control signal has been tuned to obtain the desirable temperature in the forming zone. wich The temperature differences among the measured data have been always lower than 5-10 ºC /measurements have been realized using a contact thermocouple in five points of the forming area).

Especially when the periods of the reference input signal and thrust fluctuation interference signal are not synchronous, the precision of periodic signal tracked by the servo system is reduced, which lead to the reduction of the servo system’s periodic signal tracking precision.
Multi-period discrete repetitive controller is as follows: ∙ Based on the above data, one can get waveforms in Figure 3 to 5 by Matlab7.1.

Only seize the opportunity of market demand, the development and application of linear motor and drive control technology on the market widely promotion, is bound to be in the driver with high efficiency, energy conservation and emissions reduction, promote industrial safety production from low-end to high-end equipment the development process of rapid ascension. 1.
The toy industry is also extensive use of the linear motor. [1] 2.LINEAR MOTOR OF THE CURRENT SITUATION AND TREND OF DEVELOPMENT OF THE RELATED TECHNOLOGY AT HOME AND ABROAD 2.1 The domestic status quo According to the data shows, the application of linear motor in the domestic machine tool is at the stage of development of a prototype.

Based on the energy theory and material fatigue test data, the plastic strain threshold for damage initiation was modified for HCF and LCF respectively.
The plastic strain threshold for damage initiation(pD) for HCF and LCF were modified respectively based on the energy theory and test data.
For constant amplitude loading, Nf can be written as 　　　　　　　　(1) where, pD is the plastic strain threshold for fatigue damage initiation; △p is the effective plastic strain accumulated in a single load cycle; D is the damage, which is defined as the reduction of the effective bearing area[16]; dD is the damage increment for each load cycle; Dc is the damage threshold of fatigue failure.
pD=N0﹒△p=N0﹒2εp 　　　　　　　　(7) With assumption that only tensile stress contributes to the microcrack initiation, pD can be written as 　　　　　　　　(8) Compared with Eq.3, Eq.8 is more close to the truth in the following two aspects. 1) While the material is under uniaxial static tensile load, i.e. σeq,max=σu, =σy, then and pD obtained form Eq.8 equals εpd, which is consistent with the definition by Lemaitre. 2) The value of pD obtained from Eq.8 is smaller than that from Eq.3 and more close to the test data in LCF regime.

Results of the ultimate load and damage analyses are compared to experimental data.
These data were substituted into equation (1) and solving.
The hexahedral reduction elements C3D8R are used to mesh the rods.
The simulations of this study, which include failure mode and failure regions, were shown to be good agreement with experiment data.

This paper is meant to present an overview of the existing wind tunnels, accompanied with information on some important technical data, and added, to a lesser extent, with complementary information about backgrounds and design philosophies.
Review Table 1 summarizes data of the described four wind tunnels.
All sensors and transducers are integrated into modern and sophisticated data acquisition, reduction and control system (DARCS).

The finite-element predictions are compared with experimental data including residual stress measurements using neutron diffraction.
Additionally the action of pre-loading causes significant plastic strains which may damage the material and contribute to a reduction in the fracture resistance of the material.
