Severe inflammatory reaction can in- jury the body. Thereflore, retarding synthesis of PAF, increasing catabolism of PAF or blocking the combination of PAF and its re- ceptor might be the appropriate treatment. Hitherto, antagonists of PAF have been studied extensively. More than a hundred of such antagonists have been reported, some of them having even been used in clinic and having presented an optimistical prospects, especially natural antagonists BN series and kadsurenone, which have shown sound effects in both basic and clinical experiments.

因此通过阻止PAF合成，增加PAF分解和阻止PAF与其受体结合发挥生物效应可以作为一种适宜的治疗手段，PAF受体拮抗剂研究已成为热点，天然及人工合成的PAF拮抗剂种类很多，已报道有一百种以上，有些已进入临床应用，具有较好的前景，尤其是天然拮抗剂BN系列（以BN52021为代表）及海风藤酮巳在基础及临床研究中取得了可喜成果。

It is first found that there is an important difference in order-disorder of crystalline structure between the artificial pitchblende and natural pitchblende. Unlike natural pitchblende in which uraninite nanocrystals arrange in order, the artificial pitchblende only contains disorderly uraninite nanocrystals.

在国内、外首次发现此类人工合成沥青铀矿和天然沥青铀矿在晶体结构的有序—无序上存在重大差异：天然沥青铀矿中的纳米级晶质铀矿为有序排列，而人工合成沥青铀矿中的纳米级晶质铀矿则为无序排列。

In this algorithm, the product of two huge primes is the secret information, which is further converted into n natural numbers and then encoded into planted plane cubic tree structures which are embedded into the software codes as software watermark.

水印嵌入的入程是：首先将两个大质数的乘积采取中国剩余定理划分成n个天然数，然后再将这n个天然数编码入n个平面环路树PPCT构造中，将这些构造的构建代码嵌入软件代码中。
