也就是说

Different from the case of strict minimal siphons in a net system, the number of elementary ones is bounded by the smaller of place count and transition count. Based on the ideas mentioned above, this thesis proves that the set of elementary siphons is not unique, while different ones may lead to different control results.

本文在此研究的基础上，论证了网系统中的基本信标的不唯一性，控制不同的基本信标可以得到不同的控制效果，进而提出了最优基本信标的概念并给出了相应的计算方法，应用这一计算方法可以在多项式时间内求得一组最优基本信标，也就是说，控制该组基本信标相对于其他的基本信标可以使得系统Petri网模型具有最多的可达状态，这在实际中，意味着系统具有更大的灵活性。

Digital business card printing and membership card production, is also known as variable-data business card printing and membership card production, this means that every image is varioust embossing process.

This means that attention will be super-model think a 20% increase in profit may reduce the 20% probability of error, which means that the combined increase of 40% chance of success.

也就是说关注超思模型将增加20%的盈利可能，减少20%的错误概率，两者相加意味着增加了40%的成功机会。

In that poem I cut out snippets from a source text, Erving Goffman's Asylum , mostly focusing on the words just before and after the period, in other words the interstitial dynamics of the text, the literal place of transition from one sentence to the next.

在那首诗中，我从欧文·高夫曼的《精神病院》中分解摘录，主要专注于停顿之前或之后的词汇，也就是说专注于文本间隙之间的内驱力，专注于前一个句子到后一个句子之间过渡的文字排列。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。
