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 life cycle theory of corporate governance has transformed the last full - scale governance and " single main body governance " that neglected study idea of about the relation of main bodies, and advanced the governance idea that is making clear primary and secondary and combination of them, it will reach the target that impelling the development of entire corporate governance through more fractionating phase target and emphases of corporate governance and correspondingly selecting governance measures
公司治理的生命周期理論改變了過去面面俱到的「全面治理」和忽略主體間聯系的「單個主體治理」的研究思路，提出了「有主有次、主次結合」的治理思想，通過進一步細化公司治理的階段目標、階段重點，有針對性的選擇治理方法，最終實現公司治理伴隨公司的發展而進步的目標。 -
By compared with the simulation results and the experiment results, we come to the conclusions that : ( 1 ) circuit with assistant network can widen soft - switching extent in lagging arm, reduces duty - cycle loss on the secondary, diminishes switching dissipation of inverter spot - welding power source. ( 2 ) the range of resonant capacitor, the important factor to soft - switching process, not only affects zero - voltage turn - off of power switches, but also affects the range of zero - voltage turn - on of power switches. so resonant capacitors must be considered according to many aspects ; ( 3 ) it easily fulfils soft - switching condition in lagging arm as leakage inductance of power transformer increases, but bigger leakage inductance of power transformer increases opening dissipation of transformer and decreases efficiency of soft - switching inverter power source
通過模擬結果與軟開關點焊逆變器試驗結果的對比分析，得到了如下主要結論：採用輔助網路可以完全拓寬全橋軟開關逆變器的滯后橋臂軟開關范圍，減小了次級占空比丟失，降低了逆變電阻點焊電源的開關損耗；諧振電容是影響軟開關工作狀態的重要因素，其大小不僅影響開關管的零電壓關斷，同時也影響開關管的零電壓開通范圍，因此，諧振電容應該綜合考慮；功率變壓器漏感越大，越容易滿足滯后橋臂的軟開關條件，但是大的漏感也使變壓器的通態損耗增加，降低了軟開關逆變器的效率。 -
One is that the operation duty cycle can not be larger than 50 % because of the requirement for the transformer resetting. as a result, the voltage stress of the secondary diode is high, which limits the usage of dfc in high output voltage application
但由於變壓器磁芯復位的需要，其工作占空比必須小於50 ，從而造成占空比利用率不高，變壓器副邊電壓高，副邊高頻整流二極體的電壓應力大。 -
Lithium - ion secondary battery duo to high specific energy and good cycle performance has attracted considerable attention, but its disadvantages of high cost and low safety can not been ignored by using organic electrolyte
鋰離子電池以比能量高、循環性能好的優點得到了廣泛關注，但因採用有機電解液，電池成本高，存在安全性差等不足。 -
The thesis analyses the effect of phase shift control and the utilization of the transformers primary sides saturable inductor to the transformers secondary sides voltage duty cycle, and basic on the buck converter s small signal ac model the converter s model is deserved, and infers control to output transfer function
論文通過分析移相控制方式和高頻變壓器一次側的飽和電感對高頻變壓器二次側方波電壓占空比的影響，在buck變換器小型號模型的基礎上建立了帶飽和電感的移相控制零電壓開關全橋變換器的小信號模型，推導出控制到輸出的小信號傳遞函數。 -
It displayed that gdh pathway might be predominant and gs / gogat cycle be secondary in ammonia assimilation by analysis of the activity ratios of gs / gdh and gs / gogat. results indicated that the amination capability was enhanced in the non - heading chinese cabbage leaves treated with chitosan. the enhanced amination capacity by gdh would in turn lead to the increase of the soluble protein content
進一步對酶活性的比值（ gs / gdh和gs / gogat ）進行分析表明，在殼聚糖處理后的前期， gogat可能與gdh -起執行氨同化作用：而在後期，氨同化作用主要是由gdh完成， gogat與gs組成的途徑起著輔助的作用。 -
