1. The main manifestations of the syn- drome are:(1)Peripheral polyneuropathy.

2. Applying this equivalent mechanism to make tooth—shape syn- thesis, the original, theoretic, and practical tooth shape equation is derived.

3. The byproduct copper sulfide was transformed into copper oxide by roasting, which was cyclically used in the next syn- thesis.

4. Two principal respects are embodied in the computer-aided optimum syn- thesis or design for planar linkages.

5. Objeclive To study the hemodynamic and neurohormonal changes in patients with vasovagal syn- cope during the head-up tilt (HUT) table test the triggering mechanisms of syncope.

6. Based on the researches of syn drome of TCM, it was pointed out that the standardization study of syn- drome of TCM was the key in the new environment.

7. Polyphenylene oxide was successfully added to phenolic resin during the syn- thesis process by using a modifying agent XPY, and a new modified environmental phenolic plastic was made.

8. This review describes recent advances in the synthesis of C_2-symmetric chiral bis (oxazoline) ligands and the utility of its metal complexes in the catalysis of asymmetric syn- thesis.
