simple harmonic motion

In order to determine the solution set of the equation , by the means of meet - irreducible element and irredundant finite meet - decomposition , we first obtain the maximal solutions to the simple equation in the case that b has an irredundant finite meet - decomposition , and then consider the relation between the equation and the equation , based on this , we obtain the maximal solutions to the equation in the case that each element of the matrix b has an irredundant finite meet - decomposition and so determine its solution set completely 為了確定方程的解集,本文利用交既約元與不可縮短的有限交分解等工具,同樣地先求出簡單形式的型矩陣方程的所有極大解,然后討論方程與方程之間的關系,在此基礎上,在b的每個元素均有不可縮短的有限交分解的情況下,求出了方程的所有極大解,從而完全確定了方程的解集

On the basis of simulation and experiment , the dynamic characteristic of frosting and defrosting of ashp is studied . a set of simple equations is put forward to model the reverse cycle procedure of defrost and is put into the practice to simulate the dynamic characteristics of frosting and defrosting of ashp 在仿真模型研究中,提出了一個簡單的可以用來模擬四通閥換向后系統高低壓平衡和系統循環重新建立的過程,并將這一模型應用到機組動態特性研究。

While in traditional elasticity mechanics , we make our best to eliminate the unknown variables and can get the simplest equation in a brief form . at the same time , the rank of equation is increased , so we cannot solve the equation by direct method and have to resort to semi - converse method 而傳統的彈性力學,其求解方法是盡量消元以使未知量減少,方程形式簡單,寧可讓方程階次提高,故數學物理方法中最基本的分離變量法就難以實施,只能采用半逆法。
