It s a type of authorization assertion - a statement that says that this individual can retrieve those files if it s signed by the earth system grid authority 这是一种授权声明如果一个用户通过earth system grid权威进行了签名，那么这表明该用户可以检索这些文件。
After a theoretical investigation , the thesis then suggests corresponding strategies to balance the unbalance trend of the village man - earth system from both perspectives of small - area and individuals 从微观地域、微观个体视角，提出了村域人地关系系统相应的调控措施。
So the organizations trust the earth system grid to do the access control for them and make sure that the access is only granted to users with appropriate rights 因此，这些组织信任earth system grid ，让它为他们实现访问控制，并确保访问权限只会授予那些具有适当权限的用户。
The limitation of this kind of model lies in one - grade absorber . in addition , the simplified linear roller - earth system can not really reflects real conditions 这种模型的局限性在于只有一级减振系统；另外，压路机?土壤模型简化成线性系统无法较真实的反映实际的非线性系统。
Dlese ( digital library for earth system education ) is a community - supported digital library dedicated to the collection , enhancement , and distribution of materials that facilitate learning about the earth 为地球系统教育数字化图书馆)是一个支持数字化图书馆，致力汇集、提高和发行地球材料的社区。
It also shows that earth system is very complicated and casually , and has close relationships with humans daily life . well organization and suitable choices should been done by both teachers and students on 它的学习，需要师生在共同探索新知的发展过程中完成对学习内容的选择、组织，实现探究型课程的构建。
The proposed concepts of " anthroposphere " and " anthropocene era " represent the latest development of earth system science , which further emphasize the role of human being in the changing earth system 研究证明,今天,人类的社会和经济活动的范围之广和强度之大,已经足以开始对整个地球的气候和生态系统产生显著的影响。
In connection with the construction of lightning protective earthing system in residential area , the application of non - metal earthing module was introduced and the experience learned in practice was summarized as well 摘要结合居民小区防雷接地系统工程建设，介绍了非金属接地模块在工程中的应用，总结了实际经验。
Difference from traditional earth science , earth system science faces more complex problems and needs cooperation of sciences from various fields and huge expenses on equipment instrument 摘要地球系统科学研究目标宏大、投资强度大、多学科交叉、需要昂贵且复杂的实验设备，已经从传统地球科学发展成为“大地球科学” 。
Because of the above consideration , the author puts forward one kind of nonlinear vibratory roller - earth system with two - grades absorbers and does some research work on simulation by means of the software - matlab 基于以上考虑，作者在本文提出了一种二级减振结构的压路机?土壤的非线性模型，并对该系统用matlab软件进行了动力学仿真。
