柱切換
英文
column switching-
The equations of motion governing the axisymmetric elastic deformation of finite orthotropic cylindrical shells, involving the effect of transverse shear and rotational inertia, are derived. by applying the reverberation method, the displacement and the resultant forces of the shell in the phase space are expressed. then the transient waves in the finite orthotropic cylindrical shell subjected to the axisymmetric impact are obtained by using inverse laplace transforms. furthermore, the transient solutions are decomposed to the generalized ray integrals and computed numerically
分析了計及剪切變形和轉動慣性的有限長正交異性圓柱殼中彈性瞬態波的傳播問題，採用回傳矩陣法，在相空間中給出了位移和內力的表達式。再利用laplace逆變換，得到正交異性圓柱殼受軸對稱沖擊作用時彈性瞬態波解，然後將其分解為若干廣義射線積分之和，並用數值方法求解之。Slovakia ' s mark cech hit the post after seven minutes and croatia striker eduardo da silva also came close before his shot was parried by the goalkeeper and olic tucked home the loose ball to put the home side ahead just before the break
七分鐘后，斯洛伐克的馬克.切賀打中了門柱，克羅埃西亞前鋒艾德瓦多.達.席爾瓦也有機會，但他的射門被門將撲出.就在中場休息換邊之前，奧立齊利用自由球攻入對方球門打破場上僵局Fusion expression of m - centrin in e. coil bl21 was performed by induction of fptg. fusion protein was digested by ppase and was purified by gst chelating affinity chromatography and ion exchange chromatography. the final products were checked by sds - page gel
融合蛋白gst - m - centrin菌體經過超聲波裂解后得到的上清夜經過gst親和層析後用prescissionprotease （ ppase ）酶切，酶切產物再次經過gst親和層析和hitrapq陰離子交換層析兩步柱層析純化后，得到純度較高的的m - centrin 。As we know tpk is the important key enzyme in cell growth and metabolism. so what we have done is of great significance to study further the biological functions of the new cloned protein related to bsp proteins
我們從大鼠子宮中通過deae 52離子交換柱等純化得到tpk樣品，收集有活性部分，一切操作在4t中進行，然後觀察通過基因工程得到的hbrp對tpk活性的影響。Abstract : a semi - analytical method is used to modelling the pract ical 3 - zone simulated moving bed chromatography ( smbc ) process for optimal searc hing. the switch time which is the most important operation parameter of 3 - zone smbc is analyzed based on the nonlinear batch chromatography theory firstly, and then adjusted by the deviation between the output and the expectation. the switch time approaches the optimization very soon by continously searching on the basi s of the theory. the parameters of the practical system are inputted into simulat ion, the result is used in our experiment and a good separation is obtained
文摘:針對三帶模擬移動床色譜的實際模型，用一種融合了前饋與反饋的半解析優化計算方法對三帶模擬移動床色譜過程進行了模擬.首先，由非線性單柱色譜理論解析地給出一個三帶模擬移動床色譜的主要操作參數即切換時間值，然後利用所得結果與目標量之間的偏差來校正切換時間，在理論指導下進行優化搜索，切換時間能很快達到最佳值.將測得的系統參數引入計算，並將計算結果用於實際操作，得到了很好的分離效果The ratio of story shear rigidity as well as the equivalent lateral rigidity ratio of story above the transfer story to the story under the transfer story should be designed properly to avoid the transfer story becoming weak story, thus the shear walls and the columns in the large base will not yield before the elements above the transfer story ; ( 2 ) the translation - torsion coupled effects and the vibration in the plane should be considered in analysis of structure with large base and muti - towers
轉換層的設計除應控制層剪切剛度比外，還應控制轉換層上部與下部結構的等效側向剛度比以避免薄弱層出現在框支層，保證地震作用下落地剪力墻和框支柱不先於轉換層上部結構進入屈服狀態；大底盤多塔樓結構的分析必須考慮平扭耦聯振動和樓板平面內振動的影響。Simple manipulator may do not outer connect signal or connect one - way measure signal namely can direct control operation signal output by keystroke operate, apply to differential kinds of a variety of valve manual locating control, display screen indicates measured value or output percentage, which can be self - set by customer
Wp - ks805系列智能雙迴路串級pid調節控制儀採用先進的微處理器進行智能控制。具有多種輸入信號切換功能和雙屏數碼雙光柱顯示型式。可選擇rs232 rs485串列通訊介面，並可實現多機通訊。Because of the severe limitations of this valve in respect of column switching, it was replaced by another kind of valve.
由於這種閥在柱子切換方面限制太死，所以採用了另一種閥。Abstract : based on set up a three - section simulated moving - bed system, the separation process and principle and the effects of the main operation parameters of the b - type three - section smbc are analyzed carefully. the switch time and the column asymmetry are discussed. these analysis were proved by the actual separation experiments of biphenyl and fluorene on the smbc system
