254. Mechanical test results must be evaluated in conjunction with catalyst activity, selectivity, and stability data.

255. Its chromatographic characteristics including column efficiency, operating temperature range, thermal stability, polarity and selectivity were studied,(http:///selectivity.html) and its separation mechanism was discussed.

256. This process relies on a catalyst of high selectivity and week activity.

257. The results have shown that the series of catalysts have higher acid catalytic activation, stability and selectivity to lower fatty ester.

258. The catalyst has high catalytic activity and excellent stability, both the conversion rate of TAME and the selectivity of isoamylene can be over 99%.

259. Must of the funds with high weekly return result from their excellent portfolio selectivity and have excellent anti-drop ability as well.

260. As the kernel of the 2th-order cyclic statistics variables theory, the spectrum relativity and frequency selectivity are investigated.

261. The method has high selectivity, high sensitivity and high accuracy, which could realize high sensitive analysis of trace organophosphorus pesticides in liquor.

262. Hence a higher para-xylene selectivity in isomerization reaction of xylene on ZSM—5 molecular sieves is verified based on the experimental results.
