Niger with phytase activity about 2250 u / ml which selected by protoplast - uv mutation was used as original, prepared it into fungu - suspend - liquid, through uv mutation, daub on the filter - substract. pre - primary - selection was according to the lucency - circle, primary - selection was one fungus inoculate one flask to ferment, secondary - selection was using several high phytase activity fungus through one fungus inoculate 2 - 3 flasks to ferment. then one or two high phytase activity fungus of the secondary selection were used in the next mutation cycle
首先用粗略制備的原生質體經紫外誘變篩選到一株酶活為2250u ml的實驗出發菌；制備成菌懸液，紫外燈下照射誘變，紅光下塗抹篩選平板，恆溫培養2 3d ；按透明圈大小進行預初篩，挑選徑圈比大的菌落接斜面，恆溫培養3d ；按一株一瓶的方式進行初篩；從中選取酶活較大的3 5株，按一株2 3瓶的方式進行復篩；挑取酶活大且穩定的1 2株進入下一代誘變篩選。 -
The technology of identification based on iris is researched in the article, the key point of the technology is the iris characteristic acquisition and recognition, therefore based on the iris image texture characteristic, using the wavelet transforms to get the characteristic of iris image, a new method named zero - crossing detection and secondary circle coding is used in the article
本文研究的就是用虹膜進行身份識別的技術，該技術的關鍵是虹膜特徵提取和識別。基於虹膜圖像的紋理特徵，利用小波變換來提取虹膜圖像的特徵，本文提出了基於小波過零檢測的循環二次編碼的方法。 -
These results show that since the existent defects of combustion device structure and its hypothetical circle of contact, these make a poor primary and secondary wind rigidity in operation and a too big actual circle of contact. in addition, the coal used is extreme prone to burn and reside in boiler. under such a condition, the coal powder ignites earlier in a short time and short distance when it leave the jet - combustioning device, and splashes the water cooler, eventually this results in a burned coal residue in boiler
針對宏偉熱電廠410t / h燃煤鍋爐嚴重結渣問題，對燃煤的結渣性、爐內溫度工況及空氣動力工況等進行實驗研究，由於燃燒器結構和假想切圓選擇的缺陷，使得鍋爐在正常運行時，一、二次風剛性較差，實際切圓過大，加上目前燃用煤質屬于極易燃、易結渣煤質，致使煤粉在離開噴燃器很短的時間、較短的距離內開始著火，並沖刷水冷壁，最終造成爐膛結渣。 -
And the primary and secondary relation of the factors and the optimum level of every factor were obtained as well as the best scheme of structure design in the research condition. regression equal between traction resistance and partial sphere height, bottom circle radium was set up to explore the effect of two evident factors ( height and bottom circle radium of the partial sphere ) on traction resistance by optimum calculation
採用二次回歸試驗設計的方法，建立了球冠高度和球冠底圓半徑大小與牽引阻力間的回歸方程，進行了優化計算，進一步考察了球冠高度和球冠底圓半徑大小兩個顯著性因素對牽引阻力的影響規律。 -
The paper takes shiyan city as a study case. in light of the existing urban recreationally spatial structure and its landform, the paper puts forward “ ellipse circle ” formed by “ plot - axis ”, an ideal model of recreationally spatial structure for moderate cities, which can be described as : according to “ plot - axis ” model, a city which has unique central district firstly puts emphasize on the center and its axes, secondly transfers to secondary center and its axes, thirdly gradually shapes a recreational belt crossing the center of the city, finally forms “ ellipse circle ” model for recreationally spatial structure by recreational belt. finally, the paper comes up with corresponding countermeasures aiming at the recreationally special layout of each hierarchy in shiyan city
以十堰市為例，根據城市現有的遊憩空間結構和地形特徵提出了「點軸」拉動的「橢圓圈層」城市遊憩空間結構模式，即對于只有一個中心區域的城市，根據「點軸」空間結構的發展模式，首先以中心區域為重點並發展其中心軸線，隨后把重點逐步轉到次重點區域並發展次中心軸線，照此循環下去逐漸形成橫穿城市中心區域的遊憩帶，在遊憩帶的作用下形成了城市遊憩空間的橢圓圈層模式;最後分別對城市社區、城區和環城三個遊憩空間的布局提出了相應的改進措施。 -
The growth circle and some physiology - biochemical indexes were illustrated. as the same time, the tendencies of flavonids, saponins and tea - polyphenols during growth circle are analysed. the paper provides scientific and experimental basis for cell culture and secondary metabolism matters yield
分析了在愈傷組織生長周期中山茶總黃酮、總皂甙和茶多酚的含量變化，為山茶的進一步開發，細胞培養和次生物質的生產提供理論和實驗依據。 -
They show some physiology - biochemical indexes character during proliferation and cell activities. it is different between growth - circle of callus cultured brightly and that of callus cultured darkly. 3. the change of secondary metabolism matters content : during growth circle, flavonids, saponins and tea - polyphenols were connected with callus growing condition
愈傷組織生長周期中生理生化指標的變化可溶性蛋白的變化、過氧化物酶（ pod ）活性的變化、超氧化物歧化酶（ sod ）活性的變化均與生長周期密切相關。 -
These measures are as follows : shorten the primary wind intervals to improve thermal load of the burner ; reduce the size of hypothetical circle of contact to prevent the flame from splashing ; use nozzles with larger height / width ratio to increase the effusive rigidity, so as to increase the jet flow depth of secondary wind into the main jet flow ; use a higher primary wind velocity to increase its jet flow rigidity ; use a special flame holder structure of the primary nozzle, so as to improve
這些技術措施主要有:縮小一次風間距以提高燃燒器區域熱負荷;縮小假想切圓防止火焰刷墻;採用高寬比較大的二次風噴口以增加射流剛性，提高二次風射流進入主射流的深度;採用較高的一次風速來提高一次風射流剛性;一次風噴口採用特殊穩燃結構;提高下二次風的托粉能力。
