With the development of science and technology and the deepening of globalization, the computer technology begins to permeate all aspects of people's life, and especially the method of statistical machine translation has made great achievements in recent years. In view of this, the method of statistical machine translation based on improved neural network in this paper was researched, then, through the improved neural network structure model, the pre-scheduling model and the corpus analysis method, the translation method of the statistical machine were analyzed and studied. The experiments show that the pre-scheduling model based on the improved neural network makes the translation results of statistical machines more accurate, which is conducive to promote the world information exchange.

With the continuous improvement of people's living standards, more and more people pay attention to their quality of life and health, and the awareness of indoor air quality has been greatly enhanced. Formaldehyde is one of the most important substances in many indoor air pollutants. It mainly comes from plywood and pigments which is used in interior decoration. Therefore, the detection of formaldehyde gas is particularly important. To realize the monitoring of indoor formaldehyde gas concentration, an automatic formaldehyde monitor is designed in this paper. The article uses STM32F107 single chip microcomputer to control system. First, a Dart sensor is used to collect formaldehyde signals. Then, the signal is amplified and processed by the LTC1049 data processing module circuit. On the one hand, the real-time value of formaldehyde concentration can be displayed by LCD12864. On the other hand, when the formaldehyde concentration exceeds the preset threshold, the buzzer will sound the alarm. Finally, the system realizes the real-time monitoring of indoor formaldehyde concentration. In order to improve the measurement accuracy, the method of piecewise linear interpolation is used to correct the data. The experiment shows that the system has the advantages of good real-time, convenient operation, stable performance and intelligent. The system can be widely used in the monitoring of formaldehyde content in indoor air. Copyright © 2017, AIDIC Servizi S.r.l.

This paper discusses the English learning methods and identifies the problems in English teaching and self-learning in China, and then based on the VB platform, it proposes building a platform to facilitate communication between teachers, learners and other participants. At the same time, it adopts the object-oriented development approach to analyze the construction method for the online English self-learning platform and uses UML language to design this platform. At last, this paper uses general testing methods to test the interfaces, functions, performances and security of the VB-based online English selflearning platform and analyzes the performances and deficiencies of the platform based on test results.

By means of the Hirota bilinear method, explicit representations of general rogue waves for the Mel'nikov equation are explored in terms of determinants. As applications, it is found that this system admits bright- and dark-types rogue waves localized in two dimensional space. Furthermore, the superposition of such bright rogue waves are investigated graphically by different choices of the free parameters.© 2014 Elsevier Ltd. All rights reserved.

A transform is suggested in this paper to convert fractional differential equations with the modified Riemann-Liouville derivative into partial differential equations, and it is concluded that the fractional order in fractional differential equations is equivalent to the fractal dimension.

The interactions between halogen-substituted s-trazine (C3H 2N3X) and halide anions (Y-) have been investigated at the MP2/aug-cc-pVDZ (aug-cc-pVDZ-PP) level. C3H 2N3X can interact with halide anions to form five types of complexes (C3H2N3X·Y-): a strong σ-type interaction complex, a weak σ-type interaction complex, an anion-π interaction complex, a hydrogen-bonding complex, and a halogen-bonding complex. The binding energies, structures, and bonding characteristics of these complexes have been discussed. The local details of potential energy surfaces around the binding sites for some selected complexes have been depicted. The results indicate that the binding behavior of F - is quite different from that of Cl-, Br-, and I-. The potential energy surface is separated into two parts, the HB-σ-π region and the XB region, by a relatively high energy barrier for complexes C3H2N3Cl·Cl-, C3H2N3Br·Cl-, and C 3H2N3I·Cl-. The HB-σ-π region is characterized by the flat potential energy surface, indicating that the binding strength is retained when the anion is held over the HB-σ-π region. The XB region is characterized by the steeper potential energy surface, indicating that the binding strength is more sensitive to the anion position in this region. The binding strength of the HB-σ-π region is stronger than that of the XB region for C3H 2N3Cl·Cl- and C3H 2N3Br·Cl-, whereas the binding strength of the XB region is stronger than that of the HB-σ-π region for C 3H2N3I·Cl-. © 2013 American Chemical Society.


A total of 10 skulls of Tibetan gazelle were utilized in this study. Craniometric measurements for 22 different parts of the skull were made. Skull indices and ratios were calculated. A skull index of 43.22±0.44, a cranial index of 58.37±0.80 and a facial index of 116.37±1.24 were obtained.

The fractional Boltzmann transport equation is derived making use of the fractional Hamilton's equations based on the fractional actionlike variational approach. By simply defining a distribution function and inspecting its time derivative, many important results in statistical physics can be derived. © 2011 Elsevier Ltd. All rights reserved.
