CO2 emissions from heavy-duty vehicles are an important source of greenhouse gases in the transportation sector. However, there is a lack of in-depth research on the characteristics of CO2 emission factors of multiple types of heavy-duty vehicles. The paper conducts a study on the characteristics of carbon dioxide emission factors of multi-type heavy-duty vehicles, with a focus on tractors, heavy-duty trucks, and dump trucks. A method based on C-WTVC for VSP-Bin interval division is proposed to establish a unified bin interval for heavy-duty vehicles, and calculate the CO2 emission factors of different types of heavy-duty vehicles. The study indicates that the carbon dioxide emission factors of tractors are mainly distributed in suburb and highway intervals. The carbon dioxide emission factors of heavy-duty trucks are distributed across three intervals. The CO2 emission factors of dump trucks are concentrated in suburb intervals.

The emission factors of greenhouse gases from motor vehicles are of significant importance for low-carbon and environmentally friendly initiatives. This paper focuses on greenhouse gas emission factors of heavy-duty vehicles. The multi-dimensional Bin interval mode are proposed, which considers multiple parameters such as vehicle speed, acceleration, torque, and rotational speed. Based on this, the emission characteristics of greenhouse gases from heavy-duty vehicles. are investigated under different parameter conditions. The results indicate that as the VSPA value or the engine torque increases, the CO2 emission factor also increases accordingly. The CO2 emission factor is lower at medium to high rotational speeds, while it tends to increase at low rotational speeds. The research findings provide support for monitoring and evaluating greenhouse gas emissions and offer scientific guidance for formulating specific carbon reduction policies, emission targets, and plans.

This paper proposes a multi-scale emission factor dataset constructing method. Firstly, actual road driving and pollutant emission data of heavy-duty trucks are obtained. Subsequently, a method for dividing multi-scale Bin intervals based on engine load, vehicle speed, and acceleration is proposed to establish suitable multi-scale Bin intervals for the driving characteristics of heavy-duty trucks. Finally, based on the proposed method, an emission factor dataset highlighting typical driving characteristics of heavy-duty trucks is constructed. The research findings will provide government regulatory authorities with more microscopic and multi-scale guidance on motor vehicle emissions.

Reasonable location selection of shared bicycle parking points is an effective way to solve the current problem of shared bicycles. Considering the constraints such as the amount of shared bicycles, the number of parking points, and the capacity of parking points, a dual-objective bicycle-sharing parking point location planning model considering the cost minimization of both bike-sharing enterprises and travelers is established, and the simulated binary crossover operator and polynomial mutation operator are introduced to improve the NSGA-II algorithm to obtain the Pareto non-inferior solution set that satisfies both bike-sharing enterprises and travelers. The effectiveness of the model and the superiority of the improved algorithm are verified by the case. The results show that the model and algorithm can provide a reference for bicycle sharing enterprises in the location of parking points.

Global greenhouse gas emissions are growing year after year. Although there is a temporary drop in 2021, the general trend is upward. Reduced greenhouse gas emissions are a critical goal. By evaluating the relevant literature, this research investigates the function of carbon capture systems, as well as their benefits and drawbacks. Carbon capture is a method of capturing carbon dioxide emissions at the source or straight from the air. Carbon dioxide emissions are either removed or converted into usable goods. Carbon capture technology is one of the most essential techniques of achieving zero carbon emissions. Biochar is one of the most commonly utilized because of its porous nature and capacity to absorb more substances. Biochar is primarily utilized for carbon sequestration and soil remediation. When biochar is changed using a mix of physical, chemical, and physical-chemical processes, its adsorption capability is considerably increased. The ease with which biochar may be made makes it simpler to encourage its usage. It is critical for lowering carbon dioxide levels in the natural environment.

English, as an essential skill for cross-cultural communication, underpins China’s globalization efforts. Currently, English assessment methods in Chinese universities primarily rely on traditional paper-and-pencil tests and standardized examinations. While these methods are effective in evaluating vocabulary, grammar, and reading skills, they fall short in assessing practical skills such as listening and speaking. This paper examines the current state and challenges of English language assessment in Chinese universities, highlighting its limitations and proposing improvements. The study finds that the current assessment system places excessive emphasis on test scores and neglects practical language application abilities. Through a literature review, this paper identifies existing problems in university English teaching, discusses the feasibility of diversifying assessment forms, increases the weight of listening and speaking tests, and suggests innovative evaluation methods. The paper also recommends learning from advanced foreign language assessment practices, enhancing practical tests, and utilizing modern technology for assessments to improve fairness and effectiveness, thereby promoting the comprehensive development of students’ language abilities.

This study delved into the relationship between gender and self presentation in WeChat Moments, and analyzed gender patterns and differences through questionnaire data. Using Erving Goffman’s drama theory, self presentation in WeChat Moments is viewed as an online performance, in which users play their own roles and carefully manage their online image. WeChat Moments serve as an inclusive space where users of all genders can express themselves and participate in social networks. Research has found that regardless of gender, both male and female users actively participate in posting behavior on WeChat Moments. Although male posting frequency is slightly higher, this difference is not statistically significant. The survey also found that gender has no significant impact on the composition of personal social networks and unique content creation in WeChat Moments. This study provides important insights into the role of gender in social media usage and self presentation, enriching our understanding of digital social platforms.

Taking Shenzhen stock as an example, this paper explores the opportunity for high returns in the stock market through the study of the price-to-earnings ratio, and finally determines the optimal stock market decision. By trying different numerical value on the price-to-earnings ratio and calculating the total return based on historical data, it is obtained that buying when the price-to-earnings ratio is lower than 156 and selling when it is higher than 224.5 can get the highest return. However, in the following general study of high-yield decisions, it is found that all decisions are concentrated in the rapid rise in stock prices caused by “reform cattle” in 2015 in China. Therefore, in order to study more general strategies, the scope and difference of price-to-earnings ratio are redrawn and two feasible decision-making methods are obtained: risk-averse decision-making and risk-preference decision-making. Both two decisions are suitable in a relatively stable stock market, and can earn almost the same profit theoretically, so investors can choose any of them based on their preferences.
