Development of optical manufacturing, especially aspherical manufacturing, boosted the developing of space optics. Aspheric testing for large departures from reference wavefronts becomes the bottleneck of optical manufacturing. Off-axis TMA system presented in space cameras for large field, high resolution, long focal length challenges the manufacturing and testing for aspheric components .

光学制造技术的发展，尤其是非球面加工技术的兴起，促进了空间光学的发展，大视场、高分辨率、长焦距的航天相机离轴三反系统设计的引进对非球面的加工和检测都是很大的挑战，非球面的检测技术越来越成为光学加工的瓶颈，本文从检测角度出发，提出了基于电子虚拟样板的非球面检测技术概念，建立电子虚拟样板的数学模型。

In electronic moire phase-shifting virtual plane technology, we began to research testing for the large departures from referent wavefronts and change the pattern of Offner Null testing in conventional aspheric testing, finally present the idea of electronic virtual plane.

在电子莫尔虚拟样板中，改变了传统非球面检测Offner零位检测手段，而采用直接对被测表面进行采样，获得虚拟样板的检测技术。

Secondly, the method to implement complex function with JSAI is analyzed. Then, resolved the problem of number-input by making number panel in virtual scene and resolved the problem of anamorphic dynamic undee graphics with the technology of multithreading and the method of making buffer at client.

其次，分析了使用JSAI接口实现复杂交互功能的方法；利用在虚拟场景中构建数字面板的方法解决了虚拟场景中数字输入问题；使用多线程技术和在客户端开辟缓冲区的方法解决了状态数据丢失及动态持续波形图失真的问题。

The corresponding geological, hydrogeological and professional models are set up by using the immersion sense, interaction with computer as well as realtime forecast function of VRT so that hydrogeological conditions, groundwater flow, groundwater quality , environmental geological problems such as land subsidence, sea water intrusion, soil desertification, soil salinizationalkalization, swampiness and the development tendency of cone of depression caused by groundwater exploitation, can be represented in the virtual environment.

利用虚拟现实技术沉浸感、与计算机的交互功能和实时表现功能，建立相关的地质、水文地质模型和专业模型，进而实现对含水层结构、地下水流、地下水质和环境地质问题（例如地面沉降、海水入侵、土壤沙漠化、盐渍化、沼泽化及区域降落漏斗扩展趋势）的虚拟表达。

On the two sills, however, virtual economy emerges thus fanning the modern economic society.

然而就是在这两块基石上滋生出虚拟经济来，于是构成了虚拟的现代经济社会。

The method comprises: when mobile station initiates a joint attach request or a route area/location area renewing request, if the MSC/VLR selected by the serving SGSN needs to be transferred to other MSC/VLR due to heavy load or reset, it returns a location renew acceptance message carrying virtual NRI to the serving SGSN; the according to the NRI carried in the location renew acceptance message, the serving SGSN decides if the MS needs to be transferred to other MSC/VLR; the serving SGSN reselects the serving MSC/VLR in node pool, and re-initiates a location renewing request to transfer the MS to other MSC/VLR.

当移动站发起联合附着或路由区/位置区更新请求时，若服务SGSN选择的MSC/VLR因负载过重或重启等原因需要将MS转移到其他MSC/VLR，则向服务SGSN返回携带虚拟NRI的位置更新接受消息；服务SGSN根据接收的位置更新接受消息中携带的虚拟NRI判断需要转移MS到其他MSC/VLR，服务SGSN在节点池中重新选择服务MSC/VLR，重新发起位置更新请求，将MS平滑地转移到其他MSC/VLR进行附着或位置区更新流程。

In order to improve the operator's ability of distinguishing, diagnosing, and solving printing failures, a simulation printing failures learning system was established on the applying platform of a virtual printing press. Operator can learn how to distinguish the types of printing failures, to find the causes, and to solve the problems from the simulating printed products on a virtual printing press.

为了提高操作者对印刷故障的识别、诊断和排除能力，通过建立在虚拟印刷机使用平台上的印刷故障学习系统，使学习者能够在脱离物理样机的情况下，根据虚拟印刷品学习判断印刷故障的类型、产生的原因和解决方法。

For instance, GNSS can be used to correct the odometers errors which are brought by skid and slip. Virtual balise and virtual signal can be achieved. It can reduce the cost of the train positioning system greatly by reducing trackside equipments and workload of maintenance. GNSS (Global Navigation Satellite System) develops quickly.

GNSS(Global Navigation Satellite System)可以提高列车定位的性能，例如采用GNSS技术可以对里程计打滑、抱死产生的误差进行校正；可以实现虚拟应答器、虚拟信号机，减少轨旁设备及维护工作量，大大降低系统成本。

The research of neural network realization can be traced back to 60's. It processes along with two avenues: fully hardware realization and virtual realization. Scientists have developed many neurochips supporting fully hardware realization. Neurocomputing simulating supporting environments, neurocomputing accelerators and parallel neurocomputing systems also have been developed for virtual realization of neural network.

神经网络实现技术的研究可以追朔到六十年代，该项研究一直是沿两个方向开展，即神经网络的全硬件实现和神经网络的虚拟实现，科学加们也研制出了许多支持神经网络全硬件实现的神经芯片，以及支持神经网络虚拟实现的各种神经计算软件模拟环境、加速器和并行神经计算机系统。
