This experiment passing to grope for the carbon source constitutes of the culture medium and using t. reesei rut c - 30 induced the expression of # - mannanase ( # - 1, 4 - mannan mannohydrolase ec 3. 2. 1. 78 ). in this experiment i put the constant carbon source ( lactose and locust bean gum ) in the foundation culture medium ( mandels nourishment liquid ) of t. reesei rut c - 30, then proceeded the variable carbon source ( dragon spruce fiber, com rush pith fiber, wheat straw fiber, wheat straw xylan, corn rush pith xylan, dragon spruce mannan ) to single factor, double factor, three factor, four factor and five factor orthogonal experiment. 1 determined the activity of p - mannanase using locost bean gum as substract by the 3, 5 - dinitosalicylic acid method, and observed the growing situation of the gernic at the end i selected the directions for the inducement expression of the # ? mannanase from trichoderma reesei rut - c30 that contained the dragon spruce fiber, wheat straw xylan, dragon spruce mannan
在里氏木霉rutc - 30的基礎培養基（ mandels營養液）中加入固定碳源乳糖和槐豆膠，然後將可變碳源（雲杉纖維、玉米芯纖維、麥桿纖維、麥桿木聚糖、玉米芯木聚糖、雲杉甘露聚糖）進行單因子、雙因子、三因子、四因子、五因子的里氏木霉rutc - 30正交培養實驗，並以槐豆膠為底物用3 ， 5二硝基水楊酸法測定培養液中?甘露聚糖酶的活力。從而確定了酶活最高且菌體生長良好的含雲杉纖維、麥桿木聚糖和雲杉甘露聚糖的誘導培養基為最佳培養基，用該培養基培養的里氏木霉（ t . reesei ） rutc - 30使其轉錄的-甘露聚糖酶（ - 1 ， 4 - mannanmannohydrolaseec3 . 2 . 1 . 78 ） mrna量能夠滿足rt - pcr的要求。 -

根據生態因子的限制原理，在生態因子的稀缺性指數的基礎上，提出了作物生態適宜性分析的變動賦權原理和方法，克服了傳統主觀賦權法的不足，形成了較為系統的作物地域生態適宜性評價分析方法。 -
The fatigue alternating stress, which are highly variable in time, subject the crankshaft to very high and complex loading that induced to fatigue breakdown. the crankshaft design and manufacture must therefore precise calculations of the fatigue characteristics
柴油機球鐵曲軸在工藝性和成本上佔有一定的優勢，通過滾壓強化工藝，疲勞強度有很大程度的提高，因而在國外得到廣泛應用。 -
At first an analysis of the basic principles of the vertical - axis variable - pitch turbine is given including two methods to calculate the induced velocity. one is the three different streamtube - methods which are single - disk single - streamtube ( sdst ), double - disk single - streamtube ( ddst ) and multi - streamtube ( mtt ) method based on the momentum theory, the other is the vortex method ( vtth ) based on the potential eddy theory
一是根據動量定理的流管模型得到的求解誘導速度的單盤面?單流管方法（ sdst ） 、雙盤面?單流管（ ddst ）方法、多流管（ mtt ）方法；二是根據勢渦理論得到的求解誘導速度的的渦方法（ vtth ） 。 -
In this project, the maximum height of the dam is 81m, but the deep overburden in the riverbed has the depth of 147. 95m which is about two times of the maximum height of the dam body, so the seepage and liquefaction prevention of the dam foundation becomes the key and important problem in the design of the dam project. the static stress and deformation under three different projects - horizontal blanket project, clay core project and asphalt core project - for the dam is analyzed comprehensively. the damage that may be induced by variable factors on the dam body in time of engineering completion and water impounding operation period is seriously studied
其次，將這一模型用於分析下坂地水利樞紐工程，由於該工程河床覆蓋層深度最深達147 . 95m ，是壩體高度的近兩倍左右，壩基的滲流和液化成為壩體安全主要問題，本文對該壩的三種設計方案即水平鋪層防滲方案、粘土心墻防滲方案及瀝青心墻防滲方案的靜態應力位移及壩體在竣工期、蓄水期等各個階段可能產生的破壞進行了認真研究。 -
The product variable contains two types : one is crisis factor, including disasters, induced catastrophes and affair - object - place, and the other is crisis coping strategies
最後以描述統計、單因子變異數分析、皮爾遜相關等方法進行統計分析。 -
However, dna damage has been ruled out as the prerequisite for alkylating agents - induced mutagenesis. for example, somatic hypermutation, which occurred around the variable region in the immunoglobin gene of b cells, is driven by antigen activation not by dna damage and is considered a kind of active mutation
但是dna損傷並不是引起突變的必要條件，一個典型的例子就是發生在b淋巴細胞的免疫球蛋白（ ig ）可變區基因上的「體細胞超突變（ somatichyermutation ） 」 ，是由表面抗原受體而不是dna損傷驅動的主動突變。 -
The researches show that the vertical cracks on the surfaces paralleled to water flow of thin - walled flexible piers may be induced by the large shear stresses at the faceoffs in the cross - section near the bearing and the variable cross - section of the pier
研究表明，墩身在平行於水流方向的兩側面上的豎向裂縫，可能是由於墩身在底部和中間變截面處的倒角附近區域產生較大剪應力而引起的。
