The technical key points for the soybean regional trials were the selection of trial fields, preparations in lab be-fore sowing, preparations in regional trial field before sowing, sowing in suitable time and strict with sowing process, field management and survey record, harvest and sampling as wel as lab test and summary. In addition, the approval standards for common varieties and quality varieties for the soybean regional trials in Liaoning were introduced, with the aim to provide accurate and scientific theoretical basis for the approval of soybean varieties.展开更多

METHODS: Over the course of a year, we prospectively studied a population of 66 nonerosive reflux disease patients who received a Bravo pH test. The number and frequency of all technical failures were documented, quantified and analyzed. RESULTS: A total of 66 patients, with a mean age of 41.7 years, were studied. Technical failures occurred in 15.15% of the sample. The most frequent failures were due to poor data reception (4.5%), early dislodgement (4.5%) and capsule removal (6.1%). CONCLUSION: The Bravo capsule pH test involves a low but non-negligible rate of technical problems, a fact that must always be considered by physicians.展开更多

Civil engineering technology has also changed dramatically. Civil engineering project management involves many aspects, among which the technical management is very critical. At present, the technical management of some civil construction units in our country has been done relatively well as a whole, and some enterprises are constantly improving the management system to promote the good development of business activities, reduce production losses, promote the popularity of enterprises, and promote the sustainable development of projects. Civil engineering technology is related to the level and quality of construction, and plays an important role in promoting the good development of China's economy and ensuring people's safety. The research of this paper starts from the common technical problems of civil engineering and puts forward the solutions.展开更多

At present, China's environmental protection cause has attracted more and more attention from all walks of life. Environmental testing technology refers to the process of comprehensive evaluation of environmental quality, which should make full use of physical and chemical technology and biological technology to timely and comprehensively determine the pollutants in the environment. The non-compliance of resource allocation with the standards will lead to the imperfection of environmental testing data. At present, the hardware equipment of environmental monitoring technology in our country is relatively backward and cannot provide more accurate and reliable testing data.展开更多
