The cold-shock treatment with ozonated water (ozone concentration 2 mg/L, dipping 5 min in the 1 ± 1 ℃cold water) reduced quantities of bacteria and funguses of winter-jujube, and decreased the rate of loss weight, and extended shelf-life of the fruit. By the ultrastructures of winter-jujube pericarp, cold-shock treatment with ozonated water could clean out the waxiness of crackle and lenticel, which is helpful for exchange of fruit internal CO2 and air, and inhibit accumulating of ethanol concentration.

臭氧水冷激处理(臭氧浓度为2mg/L，浸泡时间5min，水温1±1℃)可以明显降低冬枣表面细菌和真菌的数量，减少失重率，延缓冬枣硬度的下降，提高冬枣的货架期；从微观结构观察发现，臭氧水冷激处理可以清洗冬枣表皮裂缝和皮孔的蜡质，有助于枣果内部CO_2气体的排逸，从而延缓了冬枣的酒化；此外，冷激处理可以明显降低冬枣表面残留的农药：如马拉硫磷、氯氰菊酯和溴氰菊酯农药的含量，提高枣果的食用安全性。

The molecular charge distribution of the reactivator is affect the reactivating efficacy directly. Moreover its association with hydroximic acid dissociation constant pAa closely, and it will have a great impact on reactivating ability indirectly.(3) There is likely to exist front molecular interaction between Cholinesterase Reactivators and OPC-inhibited AChE, the action sites mainly lie on the aromatic ring, the substitute R and the hydroixic acid group. They act on the aromatic residues of AChE by Π-Π conjugation .(4) The reached results by Comparative Molecular Field Analysis is useful to design new higher efficacy derivatives for 1, 2, 4-oxadiazole class nonquaternary Cholinesterase Reactivators.

2复能剂分子的电荷分布直接影响复活活性，同时对肟酸解离常数pKa具有重要影响，间接影响复活能力；(3)复能剂与磷酰化酶可能存在前线轨道作用，作用部位可能主要在芳香环及其取代基R和肟基上，与AchE的芳香族残基发生л-л电子作用；(4)通过比较分子力场法研究可以指导1，2，4-oxadiazole类非季铵肟胆碱酯酶重活化剂新化合物的合成，可能得到活性更高的复能剂。

Phosphate porous starch and PVA were cross linked by methenamine and boric acid Crystal area was serious destroyed by esterification and cross linked. 6 Biodegradation experiment was carried out with soil-burying method.

5红外光谱和X-射线衍射的结构分析表明：在改性淀粉的羟基上引入了磷酰基团，并未破坏原淀粉的基本化学结构；交联剂在改性淀粉和PVA之间形成了C-O-C化学交联键；酯化和交联反应均有较强的淀粉晶区破坏作用。

The correlation between BMD and age, medical history, menopause duration, BMI, FBG, HbAlc, was analysed student's t test, analysis of variance and coefficient of multiple correlation were used. Results\ BMD decreased in all 80 patients with type 2 DM, of whom 36 (45%) were diagnosed as having OP.
