针对有色Petri网在建模能力方面的限制进行若干扩展，提出了一种扩展有色Pertri网，增加了容量限制及阈值弧函数，这将丰富CPN模型的语义，增强CPN对系统的描述能力，有助于大型复杂系统的建模，在此基础上证明了ECPN与CPN从可达空间的角度来说两者之间的等价性。

According to calculation of obstacle degree, the obstacle factor of sustainable land use was analyzed in detail. The factors such as per capita agricultural gross output value, per unit area yield of grain, reed land rate, agricultural land rate and degree of townish are the main obstacle factor ofKey words: land use; sustainability; obstacle degree; The Yellow River Delta

研究结果表明：在34个因子中人均农业总产值、粮食单产、芦苇地占地率、农业用地率、城镇化水平是黄河三角洲可持续土地利用的主要障碍因素，其中芦苇地占地率在1996年以后始终是第一障碍因素，而人均农业总产值的限制主要出现在1998年之前，之后对可持续土地利用未构成障碍；粮食单产和农业用地率的影响主要出现在1996年以后；林草覆盖率、公顷耕地农机总动力和农村电气化水平在一半以上的年份对可持续土地利用构成障碍；在1994年之前，农民人均收入障碍度较大，是主要的障碍因素。

For a long time it has been operated mainly under a passive protection --"the limited protection", which highlights protection and dispises using,thus hinderes the development of the life and production within the ruins, and limites the function of the site to play a greater role.

汉长安城遗址长期实行以&限制型保护&为中心的单一被动保护模式，这种重保护、轻利用的方式阻碍了遗址内居民生产、生活的发展，限制了遗址功能的发挥；另外随着城市建设速度和遗址外改革步伐的加快，对遗迹本体保护及遗址环境安全造成了一定的冲击，因此如何协调遗址保护与利用的关系、实现遗址可持续发展成为亟待解决的问题。

Apart from its unique performance properties and environmental benefits the Victrex PEEK-based honeycomb provides numerous other advantages including excellent impact resistance; unlike an aluminium or thermosetting honeycomb, PlastiCell's honeycomb will not remain deformed by accidental impacts during machining or assembly of the part and, due to the material's high temperature performance, the honeycombs can operate continuously up to 220°C (428°F, a thermoformable honeycomb core allows for the production of parts with short cycle times using an autoclave-free process. There is no size constraint as it is possible to make an endless honeycomb using PlastiCell's manufacturing process. Part size limitation is dictated by the hydraulic press platen size.

除了其独特的性能特性和环境效益外，VICTREX聚醚醚酮基蜂窝芯材还有很多其它优点，比如优良的耐冲击性，不像铝或热固性蜂窝芯材，PlastiCell蜂窝芯材不会在部件加工或安装期间由于受意外撞击而变形，因为该材料具有高温性能，（此蜂窝芯材的操作温度可连续达到220℃（428℉），生产热压成型的蜂窝芯材的周期短，不使用高压反应釜加工，没有尺寸限制，用PlastiCell工艺可以生产连续蜂窝芯材，液压模板的尺寸限制部件的大小。
