WebJun 3, 2024 · The application of time–temperature superposition principle (TTSP) to orthotropic creep in dry Chinese fir (Cunninghamia lanceolata [Lamb.] Hook.) was investigated through a sequence of short-term tensile creep for longitudinal (L), radial (R), and tangential (T) specimens in the temperature range of 30–150 °C. A visual … WebThe oven-dry weight of the Chinese fir specimens before and after furfurylation was recorded as m 0 and m 1, respectively. The weight gain rate was assessed by Eq. 1, (1) Equilibrium moisture content. Some oven-dried Chinese fir wood blocks were placed in a sealed desiccator with water. The relative humidity of the desiccator was measured as 96%.

WebDescription [ edit] Cunninghamia lanceolata, commonly known as Chinese fir, is a tall conifer able to reach heights of 150 feet (46 meters) in mild climates. In North America, the height typically ranges from 30 to 50 feet (9.1 to 15.2 meters). [3] In native forest land in China heights can reach up to 150 feet (46 meters) and 30 to 70 feet (9. ... WebIn this study, we selected a chronosequence of Chinese fir plantations with stand ages of 3, 8–11, 16, 21, 25, 29, and 32 years, analyzed a variety of P-related ecosystem properties (including vegetation, forest floor, and soil), and quantified the … graneva headphones
