查询词典 primitives

Authentication schemes are one of the most useful and fundamental primitives in public key cryptography which applies cryptographic methods to achieve the security services such as authenticity, integrity and nonrepudiation.

随着计算机和计算机网络的快速发展，信息安全已经成为信息社会急需解决的问题。

And The Last of the Nuba, an elegy for the soon-to-be extinguished beauty and mystic powers of primitives whom Riefenstahl calls "her adopted people," is the third in her triptych of fascist visuals.

最后的努巴人》作为对濒临灭绝的原始人的美和神秘力量的挽歌，可视为里芬斯塔尔的法西斯视觉三连画[12]的第三部分。

We take into account the onedimensional and multidimensional data partition methods, physical storage structures and further more how to parallelize them. And the implementation of primitives and basic algorithms of parallel databases are analyzed and designed.

应用先进的动态规划，网络流规划和分解协调方法，保证了整体的优化效果，可以取得明显的经济效益，并有满意的计算速度，本文提出的主问题解法，可以考虑时变的启动耗量，达到整体算法的一致性，这是以往方法难于办到的。

But for this exercise, we are assuming that we are only passing around simple primitives, and no stateful object is implied.

但这项工作，我们假设我们只通过简单的原语左右，没有状态的对象是不言而喻的。

The characteristics of image moments can be applied in manyfields. We apply Tebechbief moment characteristic to match replace of using graycharacteristic as primitives. An area moment has the property of unsensitive to transition,rotation and sealed change of area, the property of area moment is applied in the areamatching approach in our thesis, combined with a new constraint, and a novel area-basedmatching approach is proposed.

文中对Tchebichef正交矩能对图像进行精确重建的原理，利用点矩特征作为匹配基元对图像进行匹配，得到了较好的效果，并讨论了利用图像重建误差图像进行匹配的可能性和有效性；最后通过矩对区域的平移、旋转和尺度变化的不敏感特性，讨论了基于不变矩的区域匹配方法，通过引入相对位置约束提出了一种新的匹配策略。

System.out.println("a.length="+ a.length); System.out.println("b.length ="+ b.length);// The handles inside the array are // automatically initialized to null: for(int i = 0; i nbsp;b.length; i++) System.out.println; System.out.println("c.length ="+ c.length); System.out.println("d.length ="+ d.length); a = d; System.out.println("a.length ="+ a.length);// Java 1.1 initialization syntax: a = new Weeble { new Weeble, new Weeble }; System.out.println("a.length ="+ a.length);// Arrays of primitives: int e;// Null handle int f = new int[5]; int g = new int[4]; for(int i = 0; i nbsp;g.length; i++) g = i*i; int h ={ 11, 47, 93 };// Compile error: variable e not initialized://!

句柄。此时，编译器会禁止我们对这个句柄作任何实际操作，除非已正确地初始化了它。数组b被初始化成指向由Weeble句柄构成的一个数组，但那个数组里实际并未放置任何Weeble对象。然而，我们仍然可以查询那个数组的大小，因为b指向的是一个合法对象。这也为我们带来了一个难题：不可知道那个数组里实际包含了多少个元素，因为length只告诉我们可将多少元素置入那个数组。换言之，我们只知道数组对象的大小或容量，不知其实际容纳了多少个元素。尽管如此，由于数组对象在创建之初会自动初始化成null，所以可检查它是否为null，判断一个特定的数组&空位&是否容纳一个对象。类似地，由基本数据类型构成的数组会自动初始化成零、null或者false。

The Far Voxels [10] system, for instance, exploits the programmability and batched rendering performance of current GPUs, and is based on the idea of moving the grain of the multi-resolution surface model up from points or triangles to small volumetric clusters, which represent spatially localized dataset regions using groups of graphics primitives.

Far系统，充分利用了当前GPU的可编程能力与批处理能力，基于的思想是将表面模型的多分辨率的粒度从点或三角形转移到小的体簇，这些体元是使用空间区域的一组图元进行表达的。

Moreover, a contour smoothness constraint enforces consistency of primitives in the hallucinated image by a Markov-chain based inference algorithm.

一个基于马尔科夫链的推理算法用来增强图像中的轮廓平滑性。

After packing the parallel executable tasks in the task graph, the PEPs are generated in which the communication and synchronization primitives are inserted automatically.

对该任务图中的可并行执行任务进行并行封装，形成若干可并行执行包，并在其中自动地插入通信与同步原语。

For the characteristic of complex machining kinds and generous man-hour datum in manufacture enterprise,computer aided time quota predetermining system based on primitives was developed.

针对制造型企业加工种类复杂，工时数据量大的特点，开发了基于基元化理论的工时定额管理系统。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
