It adopt technique by preventing from coping screen in postil 、 siginate and seal. It can siginate for manuscript and stamper basing on PKI by 1024 RSA arithmetic,assure distinguishing and preventing disavow.It can find nonlicet sophisticate of attacker by data fingerprint,protect data facticity and integrity.

其中手写批注、签名和电子签章采取了防截屏拷贝处理技术，基于国际公认的公钥基础设施体系，通过采用RSA算法（1024位）对手写笔记和印章进行数字签名，能保证手写笔记和电子印章的可鉴别性，防止对操作的否认与抵赖，同时利用数字指纹技术能精确的发现攻击者对文档的非法篡改，以保护数据信息的真实性和完整性。

Finally, this paper introduces two kinds of blind watermarking algorithms, and then a new blind watermarking algorithm based on the nonuniform quantization is presented.

最后，本文介绍了两种数字图像盲水印技术，然后提出一种新的基于块均值的非均匀量化数字水印技术。

My calculation is based on notional figures ,since the actual figures are not yet available.

我是按估计的数字来计算的，因为还没有确切的数字。

My calculation is based on notional figures , since the actual figures is not yet available.

因尚无实际数字，我是根据估计的数字计算的。

My calculation is based on notional figures,since the actual figures are not yet available.

The orthograph maps coded according to certain specification and the geological interpretive maps can directly input the digital explorative apparatus linked with GPS. On the fieldwork the geo-workers can carry out real-time, high-accuracy position and then write down the description of geo-objects, thus the method can greatly reduce labour intensity, enhance the working efficiency and the mapping quality, and improve the research precision, research degree and research cycle of traditional surveying in deed.

按照一定规格编码的数字正射遥感影像地图及其地质解译图可以直接输入野外数字采集器，并与手持GPS连接，在野外现场实时高精度地定点和描述记录，从而大大降低野外地质工作者的劳动强度，提高工作效率和填图质量，真正意义上改善了传统区域地质调查的研究精度、研究程度和研究周期。

It attempts to identify the true owner by hiding perceptually invisible information inside the digital data. In this thesis, for the purpose of protecting the Intellectual Property Rights of digital images, a Discrete Wavelet Transform based digital watermark algorithm is described.

在这个背景下，如何防止具有版权的数字数据在未经允许的情况下，被非法的使用或是传播，这就提出新的研究的课题：就是如何运用现有的理论和技术，更好的解决数字产品所有者的合法权益的保护问题。

This article introduced the conception and structure of virtual instrument and presented a new kind of digital phasemeter based on virtual instrument technology.

介绍了虚拟仪器的概念及虚拟仪器的形成，提出一种新型的数字相位计——基于虚拟仪器技术的数字相位计。

So far, the development of digital photogrammetry, both in theory and in practice, mainly around the use of air photogrammetric mapping topographic maps, and for digital close-range photogrammetry little studied.

到目前为止数字摄影测量的发展，无论在理论上还是在实际上，主要是围绕着利用航空摄影测量测绘地形图，而对于数字近景摄影测量的研究甚少。

They go to town. Would you just ask them?

他们在城里你能问他们吗？

Ossein pretreated for a2 weeks period exhibited the maximum% yield incase of bone gelatin, while the yield from intact skin was higher than that realized incase of de-scaled skin.

预处理时间达2星期的骨胶原表现出最高的骨明胶百分产量，然而从未处理鱼皮中得到的产率比去鳞的鱼皮得到的要高。
