An effective technique to improve the reliability and correctness of a system is verification and validation of a computer information system, but they haven't any unique explicit acknowledge about the verification and validation.
Compared with no mulch,the water use efficiency under intensified cultivation was increased by 12.9%～19.3%,and grain yield was increased by 24.7%～30.2%. Therefore,intensified cultivation should be an effective technique for water utilization.
The study on groundwater environmental vulnerability is an effective technical measure for preventing groundwater from pollution, protecting groundwater resources and realizing the sustainable development of groundwater resources.
Polygonum viviparum + Carex rigescens + Kobresia bellardii) in the Luya mountains showed that it could release the characteristics of spatial pattern clearly and was a very effective technique.
Together with the cost-effective technique-Hbr display were developed in 2000.
The phase trajectories of the dynamic system are investigated using qualitative and numerical analyses, and an effective technique for searching for a physically comprehensive autowave solution of the problem is proposed.
An effective technique proposed earlier (Acoustical Physics 45 (3) (1999)) for estimating the kinetic and potential energy, the loss coefficient, and other energy characteristics of a vibrating elastic structure is improved and tested experimentally.
An effective technique is suggested for calculating the binding energies and envelope functions of the shallow donor states in type-I heterostructures with narrow wells and barriers.
The use of a cooled exhaust gas recirculation (EGR) system is one of the most effective techniques currently available for reducing nitrogen oxides.
It was shown there that effective techniques could reduce computation times dramatically (speed-up factors of 550 to 26,000 were obtained in sample calculations).
On balance, the corporation's most effective techniques of influence may have been provided not by overt pressure, but by encouraging scientists to continue thinking of themselves as independent and impartial.
Comparing the results with field data, block kriging and mapping are an effective techniques to simulate landscape pattern.
High-speed drainage structure, one of the most effective techniques to control giant debris flow disaster, has shortened one-third application life due to abrasion by debris flow.
