Firstly, the eigenvalue problem of a class of second order elliptic equation with critical potential and indefinite weights is considered. Then, using critical point theory, Trudinger-Moser inequality and the properties of the first eigenvalue, we prove the existence of a nontrivial solution for a class of nonlinear elliptic with critical potentialand indefinite weights in R~2. Secondly, we prove the existence of nontrivial solutions for a class of subcritical and critical elliptic systems with indefinite part in R~2 byusing a generalized linking theorem, Trudinger-Moser inequality and concentration-compactness principle.5. The existence of at least three weak solutions for discrete boundary value problem is established by using a three critical point theorem introduced by Ricceri.

首先，讨论了R~2中一类带不定权且含临界位势的二阶椭圆型方程的特征值问题，并借此特征值问题的第一特征值性质，利用山路引理及Trudinger-Moser不等式，证明了R~2中一类带不定权且含临界位势的非线性椭圆型方程非平凡解的存在性；其次，利用广义环绕定理，Trudinger-Moser不等式及集中列紧原理，得到了R~2上一类具有强不定部分的半线性椭圆型方程组在非线性项分别为次临界增长和临界增长情形下非平凡解的存在性。

"It's better to adopt doctor's suggestions","Chronic diseases leads to psychological impact", and "adopt preventive behaviors according to various discomforts" are three most valued health belief aspects that customers mentioned. However, the notion"to purchase and eat health foods to promote health" does not obtain much attention.

二、「依照医师的建议去采取预防和治疗的行为」、「罹患慢性病的人，心理层面会受影响」和「依照身体的不适去采取治疗和预防的行为」等三项为受访者较重视的健康信念，而就「常购买或食用健康食品让自己更健康」观念而言，则较不为受访者所重视。

54 Is not only much more systematically presented in these older writings, but gives ample evidence of a continuous cabalistic tradition; inasmuch as the mystic literature of the geonic period is only a fragmentary reproduction of the ancient apocalyptic writings, and the saints and sages of the tannaic period take in the former the place occupied by the Biblical protoplasts, patriarchs, and scribes in the latter.

一项研究的少数几个仍然存在猜测书籍披露的事实，忽略了最现代作家对cabala和essenism认为，&神秘传说&，偶尔提及，在talmudic或米大示解经文学（比较聪茨，&货车&二维版，第172页起；若埃尔阿，&万religionsphilosophie苏哈尔&页45-54岁），不仅更系统地介绍了这些年纪较大的著作，而是充分证明了一个连续cabalistic传统，因为神秘文学的若尼克期只是一个残缺不全的复制古代世界末日的著作，和圣人和智者的tannaic期间采取在原地点占领圣经原生质体，长者，文士在后者。
