The important facts noted were (1) the effect of cubic thermal expansion on the impact resistance, (2) the importance of the ground coat to the resistance of any one cover enamel, and (3) the wide variation between cover enamels in resistance to impact....
(2) The less the expansion coefficient, the stronger the effect of dispersion-strengthening. (3) Cold-worked iron or copper containing silica softens at recrystallization temperature, while that containing alumina softens little, even in austenite temperature range. 展开 ...

Based on the irreversible Brayton refrigeration cycle model, the satisfied equation about the optimal relation between the cooling rate and the coefficient of performance is derived. 基于不可逆布雷顿制冷循环模型 ,导出循环制冷率和性能系数之间优化关系所应满足的方程 ,利用数值解 ,研究内不可逆性和传热不...
A large number of polycrystalline and amorphous materials ranging from pure metals to glassy polymers have been found to obey the relations α2E=150 [dyn cm2°K2]sat normal temperatures. The linear coefficient of expansion is denoted by α, Young's modulus byE, andsis a dimensionless spread ...
In addition, we show that a firm's commitment to a policy of timely disclosure of a broader range of outcomes dampens the slope coefficient on volume in a Taylor expansion of the log of the absolute value of returns on volume. The reason for this is that when a firm commits to a ...
When using amaterial with a small coefficient of thermal expansion, it can not only detectthe dry shrinkage cracking of cement, but also detect the cracking caused bytemperature shrinkage. 8 discussion andrecommendations (1) as everyone knows, whocan improve the early strength of concrete, will ...
Non-hydraulic root source signaling (nHRS) is a unique positive response to soil drying in the regulation of plant growth and development. However, it is unclear how the nHRS mediates the tradeoff between source and sink at the late growth stages and its
6D). The correlation between physiological parameter and transcription level was assessed using Pearson correlation coefficient. The results showed that the expression level of GhCOBL22 was positively correlated with the activities of SOD, POD and CAT enzymes, as well as the content of PRO and ...
