Forward security is achieved by an evolutional parameter,which is updated with the evolution of time segment,and the group public key and members' certificates are updated along with the parameter.If a menber's private key is betrayed,the attackers can't forge the member's previous signatures.Revocation is achieved by Certificate State List,which needs the group center to update the CSL in real time,and the previous signatures of the revocative members are still valid.

前向安全性通过一个进化参数实现，进化参数随着时间段的变化而进化更新，从而使群公钥和成员证书进化更新，即使成员密钥泄露，攻击者也无法伪造该成员以前的签名；成员撤消通过证书状态列表实现，只需群中心实时更新成员证书状态列表，被撤消成员其以前的签名仍然有效。

Driven by the analyzing the synonymic characteristic of the key words and the intensity of semantic association among the ontology instances, we provide a user"s intention analysis scheme, which synthesizes the synonymic relation and the semantic association. The method can improve the accuracy and completeness of the mapping from key word to ontology entities, infer the user"s intent.

本文以查询关键字词义特性和本体实例之间语义关联强弱分析为切入点，提出了一种综合词义关系和语义关联分析的查询目标分析方法，提高了查询关键字到本体概念映射的完整性和准确性，帮助搜索引擎有效的确定用户的查询目标，解决了传统搜索引擎不能很好理解用户意图的问题。

According to the analysis of features of the key outcrop sequence stratigraphy, build the sequence frame, through the section comparison, and the study of feature of the 5 key outcrops, then it can be concluded that, conglomerate on the denudation plane or the other contrastive sediment are the main features surrounding the bottom border of the sequence. In the foreland basin sediment environment, the transilient group of mud rock and sandstone are the main sediment features of low-stand system tract. Thick mud rock and sandstone interbedded is the chief component of transgressive system tract, sometimes together with thick turbidity current sandstone; High-stand system tract is composed by the combination of mud rock and sandstone interbedded, with the progradation as its main style. Maximum flooding surface Sediment are usually mudstone, and the thickness is different from each other.

依据关键露头剖面高精度层序特征分析，通过剖面对比建立高精度等时层序地层格架，通过对5条关键露头剖面的详细高精度层序特征分析，认识到：剥蚀面上的粗碎屑岩或与之可区域对比的其它沉积是层序底部边界附近的主要沉积特征；在盆地沉积环境中，砂泥岩发育，厚层、块状砂岩与泥质岩类的突变组合是低位体系域的主要沉积特征；湖进体系域以厚层泥岩夹砂岩为主，有时夹厚度较大的重力流砂体；高位体系域为砂泥互层沉积组合，以进积式叠加样式为主；最大湖泛面多为泥岩，但其厚薄不一。

Trehalase plays an important role in glycogen accumulation in the formarion of diapaused eggs. At the beginning of diapause, glycogen phosphorylase is the key enzyme to glycogen decomposition and the formation of sorbitol and glycerol, whereas at the stage of diapause termination, NAD-sorbitol dehydrogenase is the key enzyme to sorbitol decomposition and glycogen re-synthesis.

在滞育卵形成过程中，海藻糖酶对糖原的积累起着重要的作用；在滞育开始时，糖原的分解与山梨醇、甘油的形成，糖原磷酸化酶是关键酶；在滞育解除时，山梨醇的分解与糖原的再生成时山梨醇脱氢酶(NAD-sorbito1 dehydrogenase)是关键酶。
