Abstract
From the contextual perspective of functional linguistics, this paper emphasizes the role of two types of extra-word context – situational context and structural context – in the meaning-making process of Chinese words. We found that if a word is embedded with situational context, such as the X+lǐng (领) category, the meaning-making process of the word needs to force the word-forming components to be semantically transferred in the situational context. If a word is embedded with event context (i.e. special situational context), such as the X+mén (门) category, the meaning-making of the word needs to fill the semantics of the word-forming components in the context of the event. Words rely on structural context to construct meaning. If a word contains an explicit and marked structural context, such as yǒu (有)+N, then the meaning-making of the word is also explicit, and there is no need to assign structural meaning to any one of its components. If a word contains an explicit structural context, with entry-qualified schema, such as X+N

, then the meaning-making of the word is also explicit. However, because of the relative vagueness of the grammatical and semantic nature of the components, the structural meaning tends to be transferred to a certain component, and the construction provides sufficient structural context for its new meaning-making. Based on the above analysis, this article constructs the meaning-making procedure of Chinese words and explores the semiotic values of context dependence, hierarchy, variability, and sociality that Chinese words show in the process of meaning-making.

Microbial aerosol whose species and concentrations are closely related to human health is ubiquitous. The effect of microbes on human and animal health and production performance is, in many cases, caused by the spreading of air. Samples in this experiment were from a live poultry market (LPM) in Tai'an, China, collected three times a day (8 am, 14 pm, and 20 pm) over three consecutive days each month for 11 months (Original sampling plan was a year, the government due to the environmental protection, the was LPM closed). The main indicators of the test were concentrations of cultural airborne bacteria, airborne fungi, and Gram-negative bacteria. At the same time the species of Gram-negative bacteria and the concentration of endotoxin were tested. Temperature and humidity were recorded in the process of each sampling. The results showed that the diurnal variation of the concentration of bacteria, fungi, and Gram-negative bacteria is higher in the morning and evening, but lower at noon. The concentrations of airborne bacteria and Gram-negative bacteria increased in earlier months and decreased in later months, with the peak appearing in the autumn. The concentration of fungi showed a decrease first and then tended to stabilize, with the peak occurring in the spring. The concentration peak of endotoxin occurred in the summer. Endotoxin levels were significantly correlated with humidity (r = 0.90, p < 0.01). Most bacteria were distributed at the third and fourth stages (2.1–4.7 μm) in the ANDERSEN-6 sampler. The dominant species of Gram-negative bacteria during the four seasons were Pseudomonas aeruginosa, Acinetobacter, Klebsiella pneumoniae, and Salmonella. In China, people have a habit of eating fresh poultry, LPM distribution is widespread, stream of people and traffic flow are large, easily caused the spread of bacteria and viruses, so the LPM microbial aerosol research have significant public health implications.
