In the titration experiment of NMR and IR spectroscopy, we can understand how sensors binding with metal ions: the two carbonyl group and crown ether group cooperated in binding with metal ions. Furthermore, by altering the "oxygen" atoms of crown ether to "sulfur", we can change the binding affinity to the soft metal: cupper. It shows 60-fold enhancement of fluorescence.

In the presence of NaH and in DMF, the acyclic crown ethers 1a and 1b were synthesized by the reaction of di-or triethyleneglycol ditosylate and o-methoxymethoxybenzyl alcohol, which was obtained from salicylaldehyde via the protection of the hydroxyl group with chloromethyl methyl ether followed by the reduction of the formyl group with NaBH4. The hydrolysis of 1a and 1b with dilute hydrochloric acid provided the diphenolic type acyclic crown ethers 2a and 2b respectively in good yield.

Heddewigii, Dianthus barbatus L, Dianthus latifolius, Dianthus caryophyllus and Dianthus chinensis var. liaotungensis, with relatively high fructification rates and certain traffic tolerance, showed little difference in ecological adaptability and exhibited an average seedling height of 20cm and a mean crown size of 23cm, and pruning during the late growth period could obviously promote flowering and reduce the seedling height by 3cm. While Dianthus barbatus L. and Dianthus phlox subulata, with relatively low fructification rates and higher traffic tolerance, had an unobvious difference in ecological adaptability, which present an average seedling height of 14cm and a mean crown size of 36cm, and pruning during the late growth period could promote flowering to some extent and reduce the seedling height by 2cm.

其中，大红石竹、锦团石竹、五彩石竹、五寸石竹、浓香石竹、重瓣石竹品种间差异小，平均苗高20cm，冠幅23cm，结实率相对高，有一定耐践踏能力，在生长后期进行修剪能很好的促进开花并降低株高3cm；常夏石竹和美国地被石竹品种间差异小，平均苗高14cm，冠幅36cm，结实率低，耐践踏能力稍强，在生长后期进行修剪能较好地促进开花并降低株高2cm。

Dealing with whether to keep or to rcmove activity tooth tissue valve of upper one third of rout diastema can be divided into experiment group and control group. Experiment group: keeping activity tooth tissue valve and restore it as told above. Control group: extracting activity tooth tissue valve. And then treat it in a routine way as root-canal therapy, restoration with baked-porcelain crown and metal crown.

After being loaded with horizontal retraction force at various height, displacement and stress distribution of anterior teeth was not well-distributed. Labiolingual displacement of incisors varied from crown lingual tipping to lingual translation and lingual controlling root movement, while canine mainly showed crown lingual tipping. The displacements of teeth increased with the length of hook but their moving tendency remained unchanged. Stress distribution in PDL was in accordance with teeth displacement.

2水平向后牵引力的作用点升高时，上前牙的位移和应力分布趋势各不相同：切牙的唇舌向位移由冠舌向倾斜逐渐变为舌向整体移动和舌向控根移动，尖牙则以冠舌向倾斜位移为主；前牙位移量随牵引力高度增加而增大，但位移趋势较为稳定；牙周膜应力分布与其位移趋势相一致。

Comparing with traditional cultivation system (two seasons planting cucumber with fallowing in summer), planting leafy vegetable anti garlic in summer increased the yields of the two crops anti the soil microbial biomass carbon content, total microbial population, and sucrase activity, decreased the amounts of soil nematode and root-knot nematode, and maintained a relative high Shannon-Weaver index. Planting crown daisy, garlic, and spinach in summer increased soil sucrase activity by 8.9%, 89.5%, and 36.9%, and the planting of crown daisy and garlic also increased the Shannon-Weaver index by 7.7% and 9.4%, respectively.
