When an order is form in position machine, the needed breeds and quantity of cigarette will be established and thesequence and time of cigarette sorting in an order will be also established, so before sorting an order, the order'length can be compute, but before sorting an order, the order's space is existenced as a virtual space, thus supposed a virtual space which loaded finished cigarette and order when virtual space arrive the corresponding sorter, plc control the time parameter and activated the sorting, and the sorter sorting cigarette to virtual space, an order accomplished.

对件烟行走时间进行了建模并提出了一种烟草自动分拣算法，当订单在上位机生成后，所需烟品种及数量随之确定，因此订单中所要分拣的烟分拣的次序及分拣的时刻也就可以确定，所以在订单分拣之前，订单的长度是可以计算出来的，而在未真正分拣之前，订单的长度是一个&虚拟存在的空间&，应用逆向推理的过程可假设一个装成品烟和订单的&虚拟空间&，当&虚拟空间&到达对应的分拣机位置时，通过plc对订单中件烟时间参数的控制，分拣机自动分拣件烟至&虚拟空间&完成订单分拣，该算法实现方便并能节约大量的硬件成本，对其他一些物流分拣行业也具有一定的推广价值。

It adopts the single chip computer control calculation meritorious service capacity, and parameters such as real power, reactive power, meritorious service rate element, tension fundamental harmonic virtual value and tension harmonious wave virtual value and so on these are separation to the calculation branch to the measurement that on the basis of the scattered integration formula in immediate future scattered Fourier transformation, the exchange basseted on to power system parameter sampling idea was achieved to adjust all the journey moreover the frequency alternating current frequency and the tension virtual value as well as the electric current virtual value in the way of software .

From the above seems to show the failure, the author estimated that the fault is mostly the work of the subsidiary CRT circuit damage occurred because the cathode-ray tube voltage of the focus is very prone to failure similar to the above phenomenon, the phenomenon that gave rise to such failure is due mainly to display work over time, then the CRT focus very near the jack attached to a lot of dust very easily, which encountered wet dust easily lead to the air tubes of focus very significantly decrease the performance of socket contacts, then a cathode-ray tube focus to the natural voltage decline will be affected down, so that we could monitor the performance will be prone to poor focus, image display is a relatively vague.

从上面的显示故障现象来看，笔者估计该故障现象多半是显像管附属的工作电路发生了损坏，因为显像管的聚焦极电压十分容易发生类似上面的故障现象，引起这种故障现象的原因主要是显示器工作时间一长，那么显像管的聚焦极插孔附近很容易附着不少灰尘，这些灰尘遇到潮湿的空气后容易导致显像管的聚焦极插孔接触性能大大下降，那么一来显像管的聚焦极电压自然就会受到影响而下降下来，这样的话显示器也就容易出现聚焦性能不好、图象显示比较模糊的现象了。

This paper analyzed the advantage and disadvantage of three sound wave focus methods, that is lens focus, curved autofocus, and phased-array focus on the base of draw lessons from supersonic focus technic, consequently preferred and designed the infrasonic phased-array focus system.

文中在借鉴超声波聚焦技术的基础上，分析了透镜聚焦、曲面自聚焦、相控阵聚焦等三种声波聚焦方法的利与弊，从而选用和设计了次声相控阵聚焦系统。

This study suggests that 1 Virtual museums should provide information contents based on users' requirements and therefore satisfy users' needs 2 The design of virtual museums has to focus on the usability and enhance the information flow from virtual museums to users. 3 The museum staff needs to create a virtuous circle between a museum's online and physical spaces.

依据本研究结论提出以下建议：（1）对於虚拟博物馆之资讯内容提供应依据使用者的需求而定，以满足使用者之资讯需求为目的；（2）在虚拟博物馆的网站功能设计方面，应注意网站之好用性设计，避免任何干扰使用者接收资讯的错误；（3）加强与实体博物馆的策略合作，协助使用者架构更具学习效果的博物馆经验。

Virtual Museums, like physical museums, should be developed to fulfill the missions such as educational activity, exhibition, recreation and research. However, most of the studies in virtual museums merely focus on topics such as technique, user interface and educational support services, only a few studies concentrate on users' experience in virtual environment.

虚拟博物馆本应承袭实体博物馆的展示、教育、娱乐与研究使命而发展，然而目前研究重心却多偏重於技术发展、系统好用性及如何支援正式学习之相关议题，关注使用者如何在虚拟环境中经历自发性的学习者尚属少数。

Result: In 489 rut CT natural cases discover lacuna-focus. In no-easy diagnostic shadiness lacuna-focus 502 cases, using HRCT diagnosed in deed 300 lacuna- focus ,bogus lacuna-focus 202 cases, at one time discover HRCT of up to snuff brain -organise-configurable show then rut CT preponderance.

结果：有489例常规CT正常的病例中发现了腔隙灶，在遇到的502例不易诊断的可疑病灶中，经HRCT确诊的真正腔隙灶300例，伪腔隙202例，同时发现HRCT对正常脑组织结构的显示要较常规CT优越得多。
