By properties of a real function, fixed points problem on two complete metric spaces are discussed.The result generalizes corresponding result of Fisher.Moreover, this result provides a general convergence rate estimate. Meanwhile, we discuss the existence of fixed point on two normed linear spaces under the condition of weak topology, and we obtain a new fixed point theorem.

Water stress is one of the most important abiological stress to maize seedling .In this study, we arm to identify the sensitive stage of maize seedling to water stress and select the material which tolerance to flooding. And we use waterlogging tolerance index to identify the sensitive stage of maize seedling. we have studied 20 inbred lines of maize which seedlings under water stress in three stage. The result show that the three leave stage is the most obvious stage to flood stress. In addition, we have analyzed ten of the inbred lines to re-act the waterlogging tolerance index. The result show good re-action. And the result also show that waterlogging tolerance index is a credible index to select waterlogging tolerance materials in seedling.

Using the one-atom theory, the electronic structures of Pt-electrocatalyst with fcc structure was determined as follows:(5dn)6.48 (5dc)2.02 (6sc)1.48(6sf)0.02. Compared to the result obtained by the first-principle method such as FP-LMTO, CASTEP, their results are in good agreement with each other. Comparing the calculations of physical properties such as lattice constants, cohesive energy and bulk modulus by OA method and first-principle method, the result obtained by OA method is in excellent agreement with experimental value, but the result obtained by first-principle method is not accordable. The relationship between the electronic structures and catalytic performance was explained qualitatively by OA method and first principle method according to its electronic structures. Because the d-orbital vacancies increases and static density is high around Fermi energy band, Pt has good catalytic performance.

摘 要：依据纯金属单原子理论确定面心立方结构电催化剂Pt的电子结构为(5dn)6.48(5dc)2.02-(6sc)1.48(6sf)0.02，与采用第一原理的FP-LMTO和CASTEP等方法所计算的电子结构相比较，其结果非常相近；由OA理论和第一原理方法计算的晶格常数、结合能、体弹性模量等物理参数进行比较，OA理论计算的结果与实验值较符合，而第一原理方法计算的结果与实验值相差较大；在此基础上用OA理论和第一原理方法研究了Pt的电子结构与催化性能的关系，由于d带空穴增多和费米能级附近态密度较高，导致金属Pt的催化性能很好。

Evaluating three fracture models and the result of electrical analogy. electrical analogy to the production potential of vertical fractured wells is a kind of analogy between mechanism modeling and scale modeling, the result of it is approximative and the shape of the curve is relatively good, but it is relatively bad in quantification, it can be replaced by the result of mathematic simulation.

Newborn hiccup caused by the three, first, as a result of improper care, exopathic cold, cold and heat and tend to reverse the air, As the saying goes, is "drinking the air-conditioning" and induced hiccup; Second, as a result of improper eating milk, fresh milk, if not controlled , the plot is not stopped, or have milk or too cold food served cold medicines are not qi, spleen and stomach function, abnormal movements of Qi Wei Qi move上逆hiccup induced diaphragm; Third, as a result of eating too fast or scared crying after eating, can also be induced by temporary hiccup choke.

新生儿打嗝多由三方原因引起，一是由于护理不当，外感风寒，寒热之气逆而不顺，俗话说是&喝了冷气&而诱发打嗝；二是由于乳食不当，若乳食不节制，停积不化，或过食生冷奶水或过服寒凉药物则气滞不行，脾胃功能减弱，气机升降失常而使胃气上逆动膈而诱发打嗝；三是由于进食过急或惊哭之后进食，一时哽噎也可诱发打嗝。
