So we need consider the effects of the earth curvature. In global integration, the requirement of the data coverage and the computation are comparative high. In this thesis, a moving coordinate system is used to overcome the effects of the earth curvature. And a differential calculation concept is proposed that assumes the difference of geoid calculated between the central point and its marginal point is constant when the integration area is far away from the central point.

New antifungal agents have been developed over the past years based on the discovery of many new target sites of Candida albicands. For example, Echinocandins, aiming at the cell wall of Candida albicands, showed strong antifungal activities to fluconazole resistant candidas and fungal biofilm. Moreover, because β-glucan synthase does not exist on the cell membrane of mammalian cells, Echinocandins has a low toxicity and a promising clinical future. Though the mechanism of Histatin is not clear, it has strong activity not only on candida resistant of polyene and azole, but also to Candida parapsilosis, Candida krusei and Cry ptococcus neoformans. Berberine and Ocimum gratissimum L. were also found to have prominent anti-fungi activities.

近年来相继提出了许多抗白念珠菌药物作用的新靶点并成功开发出一些活性强大，疗效确切的抗真菌药，如以真菌细胞壁为靶点开发出棘白菌素类药物卡泊芬净、米卡芬净等，该类药物主要抑制β-葡聚糖合成酶，体外对氟康唑耐药的念珠菌属及真菌生物被膜表现出强大的抗菌活性，又由于β-葡聚糖合成酶在哺乳类动物细胞内不存在，故具有高效低毒的临床效果，是一极具前途的新型抗真菌药；以真菌细胞膜为靶点开发出Histatin类药物，虽然作用机制目前还不完全明了，但其作用不同于临床常用的多烯类和氮唑类，并已经发现Histatin5对两性霉素B和氮唑类耐药的念珠菌有效，并且对非白念珠菌如光滑念珠菌、克柔氏念株菌、隐球菌等也有杀灭作用；通过对植物药物的研究发现黄连素和丁香罗勒Ocimum gratissimum L。

采用加入复合剂提高锂基润滑脂和锂-钙基润滑脂的滴点，加入草酸复合剂对所制备的锂基润滑脂的滴点的提高最为有效，加入癸二酸复合剂对锂-钙基润滑脂的滴点提高效果最好。

This method selects two parameters, energy and variance, as the characteristic parameter of trolley track, and successfully in extracts the feature frequency belt of trolley track vibration. Furthermore, this technology is applied to practical engineering programs and has good veracity and reliability.2. According to the research of this thesis on the trolley tracks\' present data, the status classification of trolley track with normal distribution is presented. This method divides trolley tracks\' situations into five parts and perfects the classifying method of trolley tracks\' mechanical situation.

具体工作如下；1、将小波包分析方法运用到岸桥小车轨道振动信号的分析中，选取能(来源：A65BC0f论c0文网www.abclunwen.com)量与方差作为轨道的振动特征参数，有效提取出铰点部位与非铰点部位的振动特征频段。2、将正态分布原理引入到岸桥小车轨道铰点机械性能状态的划分之中，并用最大熵概率分布加以验证，准确地反映了实际情况，并定义了正态分布诊断准则的状态分级评价的原则和临界点，方便和简化了状态判断的决策过程。
