6. since the monitor precision of quasi - dynamic calibration system is very important, the model of the four channel electric pressure - measuring system in frequency domain is built up. the cause of variance is analyzed. the error function of the system is defined and the formula of correcting the system error is derived
6由於落錘液壓動標裝置校準系統的校準壓力監測精度極為重要，本文對四路電測壓力系統進行頻域建模，分析了產生不一致的原因，定義了系統的誤差函數及推導了統一誤差模型的修正公式。In the present experiment studies, an acute traumatic model of lateral cortical impact was employed to study expressive changes of microtubule associated protein - 2 ( map - 2 ), cyclooxygenase - 2 ( cox - 2 ), glial cell line - derived neurotrophic factor ( gdnf ), caspase - 3 mrna and protein after brain injury in rats. immunocytochemical staining, western blotting, nucleic acid in situ hybridization with an oligonucleotide probe and computer image analysis were used to detect the dynamic changes of map - 2 mrna, cox - 2 mrna, gdnf mrna, and caspase - 3 mrna in the cortex after moderate traumatic brain injury ( tbi )
本實驗從自行設計大鼠腦損傷落體打擊器開始，先行建立了一個便於觀察和施加處理因素、控制性好、重復性好的動物模型，選用30g擊錘從25cm高處下落，沖擊應力d為355 . 09kpa ，打擊大鼠右頂部，造成中等程度的閉合性腦損傷，從病理形態學、組織超微結構觀察及微管相關蛋白- 2 （ microtubuleassociatedprotein2 ， map - 2 ） 、環氧合酶- 2 （ cyclooxygenase2 ， cox - 2 ） 、膠質源性神經營養因子（ glialcellline - derivedneutrophicfactor ， gdnf ） 、 caspase - 3基因及蛋白表達的時間性變化，詳盡系統地闡述腦損傷后各指標變化的時間規律性及表達差異可能的形成機制。
