The development of software engineering technology in the network era
Full text linksoftware engineering technology is an organic combination of computer technology and program design, covering design
language, system platform, software development and database design, which is widely used in life. Software engineering technology is
inseparable from the support of the In ternet. Due to the complexity of the Internet environment, software engineering technology is prone
to encounter security problems in the use process, which is a problem that researchers need to solve. Software engineering technology R
& D personnel should actively use software component technology to optimize the assembly of diff erent software and improve the quality
of software engineering technology; Optimize role oriented software design, customize software functions for users, and improve user
satisfaction; To meet the challenges of the “Internet +” era, we should use cloud computing, blockchain, big data and other technologies
to innovate software engineering technology; Focus on network security issues, improve application detection technology, and ensure the
security of software engineering technology
Discussion on the development trend of inorganic nonmetallic material industry
Full text linkIn the new era, social and economic development has led to the transformation and development of high-tech industries, and
many new scientifi c and technological products have emerged. The development of various industries cannot be separated from the support
of new materials. This paper describes the development of inorganic non-metallic materials, the main classifi cation, analysis of the current
development and application situation, combined with the development of inorganic non-metallic materials in the problems, to explore the
future development trend
High Pressure Raman Spectroscopy of 4-Azidobenzoic Acid
Full text linkWith the rapid development of science and technology, people’s demand for energy materials is increasing, and researchers’
exploration of energy materials is also more and more in-depth. Azide is a kind of nitrogen rich energetic material. In recent years, the
research on azide mainly focuses on the synthesis of polynitrogen under the condition of changing pressure. This is because under the action
of pressure, the azide group in the azide will hybridize the electronic orbit, and the adjacent azide groups will re combine in the form of
single bond, so azide is considered to be an ideal precursor for the synthesis of polynitrogen under high pressure. In this paper, the Raman
spectra of 4-azidobenzoic acid at ambient pressure were analyzed, the high-pressure Raman spectra of 4-azidobenzoic acid were measured,
and the phase transition of 4-azidobenzoic acid under high pressure was discovered
Voice of Climate: Focus on GGDP
Full text linkGreen development has become a global goal for sustainable development. However, traditional GDP is unable to eff ectively
refl ect the level of economic growth of an economy, let alone consider its relationship with the natural environment and ecosystems.
Regarding the fi rst issue, this paper proposes a suitable GGDP calculation method, which includes traditional GDP, the value of natural
resource depletion, the value of environmental pollution, as well as the benefi ts of resource and environmental improvement. We use partial
least squares regression analysis (PLS) to model and accurately quantify the impact of GGDP variables on climate response indicators. The
results show that the selected GGDP method can signifi cantly correlate and refl ect climate change.
Regarding the second issue, this paper uses dynamic multivariate time series models (ARIMAX) and vector error correction models
(VECM) to predict the impact of China’s climate mitigation. Cointegration tests were performed to determine the long-term equilibrium
relationship among these indicators, and residual stationary white noise tests were conducted. The future 10-year GGDP was estimated using
the quadratic curve estimation method, and future changes in climate indicators for the next 10 years were predicted using a multivariate
time series model. The research fi ndings indicate that using GGD P instead of GDP has a positive impact on global climate mitigation
Empirical Research of “Java Programming” Practical Training Base on OBE Theory
Full text linkThis paper demonstrates the eff ectiveness of outcome based (OBE) teaching of practical training course in object-oriented
programming in Java by designing a set of OBE project-oriented teaching model applicable to Java practical training of object-oriented
programming in higher vocational colleges. The fi ndings show that outcome based (OBE) teaching is eff ective in the practical training
of object-oriented programming in Java and serves as an experimental research example for the higher vocational programming practical
training course
Effective Calculation Methods of Reference Sound Velocity in Shallow Sea Environment
Full text linkThe conventional underwater passive direction finding method estimates the target angle through beamforming. The reference sound velocity in horizontal linear array beamforming should use the phase velocity of sound propagation. In passive direction finding, because the target distance is unknown, there is a deviation between the reference sound velocity selected in the target angle estimation and the phase velocity, which affects the direction finding accuracy. In this paper, two methods for calculating the reference speed of sound are presented: the normal amplitude weighting method and the beamforming method. The numerical simulation results under shallow sea propagation condition show that the reference sound velocity calculated by the two methods has the same trend as the distance between target and array
