查询词典 controlled variable

Based on the laminate theory, a laminate weakened by damage is treated as an anisotropic thin plate. Using the complex potential method in the plane theory of elasticity of an anisotropic body, the series solution of finite anisotropic thin plate containing an elliptical inclusion is proposed with the help of Faber series. A hybrid element with an elliptical inclusion for anisotropic materials is obtained by using the hybrid variable principle, and the element efficiency is verified by numerical examples. The state of the damage is modeled by an elliptical soft inclusion, and using the point stress criterion based on characteristic curve and Yamada-Sun etc. criteria, the prediction of the strength of a composite laminate with damage is set up. The effects of various parameters on the stress distribution and the residual strength of a composite laminate weakened by damage are detailedly studied.

(1) cerebral ischemical reperfusion injury rats'limbs motor function is variable. Acupuncture could promote lims'functional recovery.(2) PCNA masc cells is visible in cerebral ischemical semidarkness region. There is cell regeneration phenomenon. Acupuncture could strengthen injury region's PCNA expression, could profit injury recovery and functional reconstruction.(3) In ischemia semidarkness region for the model group and acupuncture group, PCNA masc cells percentage of 14days group is lower than 7days group. Along with the recovery of injury, cell multiplication is weaken.(4) In cerebral ischemia semidarkness region, there is VEGF masc cells and regeneration phenomenon. Acupuncture could strengthen injury region's VEGF expression, could profit protection after injury and blood vessel regenerate.(5) In ischemia semidarkness region for the model group and acupuncture group, VEGF masc cells percentage of 14days group is lower than 7days group. Along with the recovery of semidarkness region, ischemia and anoxemia state is getting improved, and VEGF is reduce.(6) As there are PCNA and VEGF masc cells in brain injured region, we could conclude that, after brain ischemical reperfusion injury, there are blood vessel regeneration phenomenon. Acupuncture could promote blood vessel regeneration, recovery blood supply sufficiently and quickly, and promote the recovery of brain injury region.(7)The VEGF masc cells percentage of inhibitor group is lower than acupuncture group. It state that the effect of acupuncture promote VEGF is partly depend on the existing of eNOS.

实验结论：(1)脑缺血再灌注损伤后大鼠的肢体运动功能发生改变，针刺可以促进肢体功能恢复；(2)脑缺损伤区可见PCNA阳性细胞，存在细胞再生现象，针刺可以增强损伤区PCNA的表达，有利于损伤的修复和功能重建；(3)针刺组和模型组14d时缺血损伤区PCNA阳性细胞百分比低于7d组，随着损伤逐渐得到修复，细胞增殖现象减弱；(4)脑缺血损伤区可见VEGF阳性细胞，存在内皮型细胞再生现象，针刺可以增强损伤区VEGF的表达，有利于脑损伤后保护和缺血区血管再生；(5)针刺组和模型组14d时缺血损伤区VEGF阳性细胞百分比低于7d组，随着缺血损伤的修复，缺血缺氧状态得到改善，产生的VEGF减少；(6)由于脑损伤区同时出现PCNA阳性细胞和VEGF阳性细胞，前者是增殖细胞的标志，后者是促进血管再生的重要因子，可以推断，脑缺血再灌注损伤后脑内存在血管再生现象，针刺可以促进损伤区的血管再生，更迅速而充分的恢复损伤区的血供，促进脑损伤区的修复；(7)抑制剂针刺组脑损伤区VEGF阳性细胞百分比与针刺组相比有不同程度的降低，说明针刺促进缺血损伤区VEGF表达部分依赖eNOS的存在。

With the combination of lighting, cooling and heating under daylighting, the study on the effect of the key characteristic parameters on total energy consumption is provided. The validation of the comparability of daylight distribution for building antetype and model is made through theoretical analysis and simulating calculation in the thesis. Due to the variable sky condition, daylighting factor is used for experimental validation instead of illuminance. The error analysis of several testing methods used in the experiment is conducted, followed by the experimental validation of the effect of WWR, sill and transmittance on daylighting factor distribution.
