Then the matrix Having these solution vectors as its column vectors is called a fundamental matrix for the system in Fundamental Matrix Solution Because the column vector .

則以這些解向量為列的矩陣被稱為這個(gè)系統(tǒng)的基本矩陣国产一级婬片日本高清视频一。

Of the fundamental matrix in (2) satisfies the differential equation =A , it follows that the matrix = itself satisfies the matrix differential equation Because its column vectors are linearly independent, it also follows that the fundamental matrix is nonsingular, and therefore has inverse matrix .

基本矩陣的求解由于（2）中的基本矩陣的列向量滿足微分方程A国产好福利影院，進(jìn)而這個(gè)矩陣本身就滿足矩陣微分方程。

Ethyl cellulose membrane material has produced in physical modification method. The fundamental characteristics of reverse osmosis on EC membrane can be correlated with HPLC experimental conditions. By using EC membrane material as column packing, double-distilled water as mobile phase, the retention times are measured with suitable inorganic and organic compound as solutes.3. Complying with the retention times, the partition coefficient of the solute and the ratio of the surface excess concentration of solutewith the concentration of the parent fraction are calculated .

利用物理改性的方法研制了乙基纖維素(Ethyl Cellulose高清一区二区三区视频久草，簡稱EC)膜材料为搞点激情，并將其作為高效液相色譜柱的固體填料，以高效液相色譜模擬反滲透實(shí)驗(yàn)平衡條件国产精品性色AV，以水為流動(dòng)相免费看黄色网站大全，選擇合適的無機(jī)物和有機(jī)物作為溶質(zhì)，測定乙基纖維素對(duì)它們的相對(duì)保留時(shí)間及平衡分配常數(shù)K_A′黄色一级片试看。3国产精品黄色网站一级大片手机版免费看。
