film factor-
The cloning cdna fragment was extracted from positive clones and sequenced. the results showed that the cdna fragment was 816bp in size, encoding a protein which included 272 amino acids. the sequence homology analysis was carried out via the software blast 2. 0 network service in the four large databases - genbank, embl, ddbj, pdb, which had recorded 1 337 978 nucleotide and protein sequences. the results of the analysis indicated that the nucleotide homologous rates between the rubber tree etr and 15 recorded etrl of other plants ( mango, passion fruit, persia plum, strawberry, grape. . etc ) were 75 % - 80 % ; the protein homologous rates between the rubber tree etrl and these recorded etrl genes were 90 % - 95 %. from the results mentioned above, we could confirm that the cdna of rubber tree etrl had been cloned
從陽性克隆子中提取克隆片段，經序列測定分析，結果表明，克隆片段的cdna大小為816bp ，編碼的蛋白質包含272個氨基酸。基因序列通過blast2 . 0networkservice軟體對genbank ， embl ， ddbj ， pdb四個大型數據庫中記錄的1337978條核酸和蛋白質序列進行序列相似性檢索，結果表明與芒果、一西番蓮、波斯梅、草毒、葡萄、西洋梨等15種已報道的植物的etrl基因cdnag的同源率為75 88 ；蛋白質氨基酸序列的同源率為90 95 ，表明本研究確實克隆到了橡膠樹etri基因的cdna序列。 4The article proposed one kind of new image restoration method : through the analysis of the reason of the image degeneration, using the fourier transforms theory and the optical system theory, through the union of mathemetics, optics and digital image processing the discipline and so on, established the new model of image restoration, caused x light fiim of the digitized image clarity greatly to enhance, basically has realized x light without film
文章提出了一種新的圖像恢復的方法：通過分析圖像退化的原因，利用傅立葉變換理論及光學系統理論，通過對數學、光學及數字圖像處理等學科的結合，建立了新的圖像恢復模型，使得x光片的數字化成像的清晰度大大提高，基本實現了x光片的無膠片化。The automatically inspect and control system for thickness of tire cord fabrics is not equipped for the calendar machines that made in china up to now. because of the thickness of tire cord fabrics is measured and controlled by manual, the quality of products cannot be guar anteed and a lot of rubber compound were wasted. in the article, the data process and data read of the other calendaring process parameters have designed
另外，由於被控制膠片厚度較薄，若控制系統執行機構大幅度動作，嚴重時有可能造成壓延機兩輥相抵，使輥筒斷裂等重大的設備事故，因此，在常規控制的基礎上，通過採用增量式調節的特點，來實現厚度的自動控制，建立並推導切合現場實際使用的數學檢測公式和數學控制模型，然後通過編制相應的計算機軟體來實現控制的目的， 。
