define vt. 1.为…立界限,限定,规定。 2.(弄)明确。 3.为…下定义,定界说。 be well defined 划分明白。 define one's meaning [position] 明确自己心意[立场]。 ill-defined duties 权限不明的任务。 a well-defined word [figure] 意义明确的文字[轮廓分明的图像]。 the defining moment 决定性时刻。
Windows contains a pre - defined set of performance counters with which you can interact ; some of these are found on all windows 2000 computers and some are custom to specific applications and are found only on certain computers Windows包含一组预定义的性能计数器,您可以与它们进行交互;它们中有些存在于所有的windows 2000计算机上,有些是为特定应用程序定制的,只存在于某些计算机上。
While instance authority levels are used as a mechanism to assign a pre - defined set of administrative rights to a group of user accounts , privileges are explicitly assigned to individual users or groups to allow them to perform specific activities on database objects for example , to create and drop an index 实例权限级别这种机制用于将一组预先定义的管理权限授予一组用户帐号,而特权是明确分配给单独用户或组的,允许他们在数据库对象上执行特定操作(例如,创建和删除索引) 。
Due to the development of 1c technology , now a complex system can be integrated in a chip called system on chip ( soc ) . the design of soc needs new design methodologys and modeling tools . systemc is an open c + + modeling platform promoted by the open systemc initiative , which consists of a well defined set of c + + classes and a simulation kernel , supporting design abstractions at the register - transfer , behavioral , and system levels . the advantages of systemc include the ability for hardware - software co - design , the ability to exchange ip easily and efficiently , and the ability to reuse test benches across different levels of modeling abstraction 系统级芯片的设计需要新的设计方法和建模工具。 systemc是osci ( opensystemcinitiative )组织制定和维护的一种开放源码的c + +建模平台,它由一个定义良好的c + +类库及仿真内核组成,支持对系统进行寄存器传输级,行为级和系统级的描述。 systemc的优点包括对软硬件联合设计的支持,更高效和方便的进行ip交换,以及在不同的抽象模型间复用测试基准的能力。
