Combining the performance evaluation (activity, selectivity and stability) and the characterization of the catalysts (XRD, TPD, FTIR and the pore structure measure), it can be concluded that :(1)The activity of modified β is higher than MCM-22, but the selectivity of ethylbenzene is lower about 3% than that of MCM-22;(2)The mounts of diethylbenzene and the other by-products are higher 1.7 times and 1.5 times than these of MCM-22 respectively;(3)The catalytic performance of zeolite mixture is nearly equal to modified β, but the selectivity of ethylbenzene is higher about 0.5% than that of modified β;(4)The catalytic activity of zeolite is mainly correlated with the number of acid sites, strength and distribution, and the distribution of products is determined by the binding energy of ethylbenzene and the pore structure, while the stability of catalyst is affected by the amount of poly-ring aromatic alkylate and the pore structure.

以性能评价和特性表征（XRD、TPD、FTIR和孔结构测定）相结合的方式，对上述三种催化剂性能比较的结果表明：（1）改性的活性明显高于MCM-22，但乙苯选择性却低于MCM-22绝对差约3%；（2）改性(上二乙苯和其他副产物的生成量分别约为MCM-22上对应值的1.7和1.5倍左右；（3）混合型催化剂的性能与改性相仿，但乙苯选择性提高0.5%左右；（4）对乙苯合成，沸石催化剂的活性主要取决于其B酸中心数、酸强度及酸分布，产物分布则取决于催化剂表面的乙苯脱附能垒值和孔道结构，而稠环芳烃的生成量和催化剂孔道结构是影响催化剂稳定性的主要因素。

Increasing the calcining temperature at 1500℃ 5h, the morphologies of the product became the big and wide vermiform-fiber form particles, the length was about 2.5 μm, and the width was about 700 nm. In addition, the vermiform-fiber form particle could be found in the filtrated precipitate with the additional ammonium sulfate. If the ratio of ammonium sulfate to alum is above 1, the vermiform-fiber form particle was formed. After calcined at 1500℃ 5h, the particle grow up to 2μm. Adding ammonium sulfate was also reduced the particles size of alumina because the surface area of the products was increased by increasing the quantity of ammonium sulfate.

在明矾与氨水沉淀物经过滤后再额外添加不同硫酸铵的比例，1200℃ 1hr煅烧后，发现添加硫酸铵比例在1以上，其型态亦为蠕虫状纤维，当以1500℃ 5hr煅烧，蠕虫状纤维型态粒子亦变为又大又胖，其粒子尺寸长度约为 2 μm 宽度约为 500 nm；且将煅烧1200℃ 1hr测其比表面积值，会随著硫酸铵的添加量增加，粉体的表面积会增加且粉体变细，添加硫酸铵比例为 4 者所得粉体粒径最小，从比表面积所得结果估计约 150 nm 。

"There's a little known and not that well investigated finding that if you have an amnesic person who can't remember the past, they're also not at all good about thinking about what they might be doing tomorrow or envisioning any kind of personal future," McDermott explains.

麦克德尔莫特解释到，"一项鲜为人知的调查研究发现，假如你是一个不能回忆过去的健忘者，那么你也将在考虑明天可能会做些什么或者预见个人未来方面表现欠佳"。

"There's a little known and not that well inestigated finding that if you hae an amnesic person who can't remember the past, they're also not at all good about thinking about what they might be doing tomorrow or enisioning any kind of personal future," McDermott explains.

McDermott解释道："之前的这些研究发现健忘症患者不仅记忆力不好，而且他们的预知力也很差，他们不善于规划明天的活动或者展望以后的人生。"

In the model of tumor cells metastases with cell line A673, 10〓 tumor cells can be detected after only one ampliation with outer primers, which means we can find 1 tumor cells in 10〓 normal PBMC, and enlarged again with inner primers, 10〓 tumor cells can be detected, which means we can find 1 tumor cell in 10〓 normal PBMC. In the simulative model of tumor cells metastases with RNA, 10〓 tumor cell can be detected that is to say we can find 1 tumor cell in about 10〓 normal PBMC. In all 15 samples of 11 patients, 2 patients'EWS/FLI1 expressions were negative, no evidence of metastases was found followed up by 8 months and 30 months respectively. Semi-quantitative study was used to detect the expression level of EWS/FLI1 mRNA in the other 9 positive patients, and metastases occurred in 6 high-level expression patients in 2-24 months after the operation, no evidence of metastases in the other 3 low-level expression patients up to now.

应用A673细胞系建立的肿瘤转移模型，单独应用外引物进行一次扩增，可以检测到10〓级肿瘤细胞，即可以从10〓个正常细胞中检测到1个肿瘤细胞；而在此基础上再次应用内引物扩增，则可以检测到10〓级肿瘤细胞，即可以从10〓个正常细胞中检测到1个肿瘤细胞；在用RNA模拟的肿瘤细胞转移模型中，两次扩增可以检测到10〓级肿瘤细胞，即可以从10〓个正常细胞中检测到1个肿瘤细胞。11例患者的15份标本中，2例没有检测到EWS/FLI1 mRNA的表达，分别随访8个月和30个月，没有发现临床转移的证据；对其余9例阳性表达的病例进行半定量的研究，6例EWS/FLI1 mRNA高表达的病例，分别在术后2-24个月发生转移，而3例EWS/FLI1 mRNA低表达的病例，则至今没有发现转移的证据。
