This paper makes a comparative analysis on the function of six cross-database search systems such as SearchLight, NLM Gateway, ISI CrossSearch, CALIS, CSDL and CNKI at home and abroad. In aspects of resources navigation, search function, search results display, content sensitive links, personalized service, special function, as well as other functions, the author puts forward some suggestions on the perfection of cross-database search system function.

选取国内外较有代表性的6个跨库检索系统：SearchLight、NLM Gateway、ISI CrossSearch、CALIS的统一检索平台、CSDL的集成检索系统、CNKI的跨库检索系统，从资源导航功能、检索功能、检索结果显示功能、内容敏感链接功能、个性化服务功能、特色功能、其他辅助功能7个方面对其进行比较分析，提出完善跨库检索系统功能的几点建议。

The new methodof defining spline function will generalize the concept to the more universal Hilbert space. Hence, we take into consideration the interpolation spline function, general linear differential operater in semi- open interval and the Green function defined accordingly, and the reproducing kernel to produce the Green function and prove the existence of the reproducing kernel.

采用了一种新的样条函数的定义方法，把样条函数的概念推广到更一般的Hilbert空间上，再考虑半开闭区间a，+∞上的插值样条函数，一般线性微分算子及其定义的Green函数和再生核，构造出Green函数并且证明了再生核的存在性。

Antibacterial function of body wall was conducted by the following way: microorganism was directly resisted through the change of cuticle, such as incrassation of up-cuticle protuberance and increasing length of micro-floccus in the up-cuticle dissociation surface; exudation function of large granular orthochromatic mucous cells and reticulation mucous cells in the epidermis could be enhanced when the Eisenia fetida was induced by E. coli. Moreover, the mucus that contained compound substance of mucopolysaccharide and protein could make the bactericidal function or dilute the microorganism on the surface of earthworm, which could protect earthworm from invasion of microorganism; the content of neutral mucopolysaccharide of antibacterial function could be increased according with the exudation increment of small granular proteinaceous cells in the epidermis, which could resist bacteria invading into the epidermis of earthworm.

结果表明：蚯蚓的体壁主要是通过以下途径来抗细菌的侵袭：一是通过角质层的变化(如上胶层突起的增厚、上角层游离面中微绒毛的变长等)直接抵抗微生物的入侵；二是增加表皮中大颗粒粘液细胞和网状细胞的分泌功能，分泌出大量含有粘多糖蛋白液体复合物的粘液，在蚯蚓体表对细菌进行稀释或者起到直接杀菌的作用；三是通过增加小颗粒蛋白细胞的分泌作用，在蚯蚓的表皮中分泌出更多的抵抗疾病的中性粘多糖，从而抵抗进入蚯蚓体表内的细菌。

Another important factor to consider is that compilers without partial template specialization or function template partial ordering support cannot handle the first form when f is a function object, and in most cases will not handle the second form when f is a function or a member function pointer.

还有另外一个重要因素，某些编译器不支持模板部分特化或者函数模板局部重排，所以当 f 是一个函数对象，或者 f 是一个函数指针或成员函数指针时，编译器无法处理。

Through Design Structur Matrix and Critical Path Method of Network Planning Technology,the project breakdown function, the project planning function and the project attemperment function are achieved; through the New-Gunter Draft the project's real-time distribute surveillance function is realized.

通过对工程变更三要素：变更流程、人员组织和产品数据的分析，建立了工程变更的三维模型，实现了规范、有效的工程变更管理。

A node payoff function which involved of utility function and cost function is modeled in the algorithm and the transmitting power vector is obtained by parallel update. It is proved that the sensor network can reach Nash Equilibrium with this transmitting power vector, and in this situation all the nodes' payoff function is maximized.

在算法中为传感器节点构造包含效用函数和代价函数的支付函数模型，通过并行迭代的方式获得网络功率控制的纳什均衡策略，使所有节点的支付函数达到最优化。

In this chapter, the penman put forwards that decomposition of government function, consolidation of government function and innovation of government function are the changing approach of our country's government function.

在这一章，笔者主要抓住我国政府职能的现存问题，从调整政府与企业、政府与市场、政府与社会的关系以及中央政府与地方政府的关系入手，指出实现有限强势政府职能模式的途径包括政府职能的分化、强化和创新。

As a result of conservative perturbations, the first order Melnikov function for a perturbed system is identically equal to zero, so the second order Melnikov function has to be considered. The perturbation parameters which make no use in the first order Melnikov function may be important in the second order Melnikov function.

此时一阶Melnikov函数恒等于零，必须考虑二阶Melnikov函数，而在一阶Melnikov函数中不起作用的扰动参数在二阶Melnikov函数中却起着非常重要的作用，因此扰动部分极为复杂。

According to poisson distribution and percolation theory, we construct stock price model, and use characteristic function to prove the convergence of this model, we can get that the characteristic function of the constructed model converge on the characteristic function of the Black-Scholes function.

根据泊松分布和渗流理论构造了股票价格的随机模型，并利用特征函数的性质论证了该模型的收敛性，得出所构造的股票价格随机模型的特征函数收敛到某一个Black-Scholes公式的特征函数的结论。

The second part includes the definition of positive definite function and conditional positive definite function, the basic form of Radial Basis Function interpolation, the correctness of the inversion of the interpolation matrix, the error estimate based on Kringing function.
