A novel polymer of Poly(diglycidyl maleate-co-stearyl methacrylate) was synthesized and its structure was characterized by ~1H NMR. Its self-assembly behavior was studied in different solvents. It was found that vesicles and tubule-liked aggregates can be obtained through self-assembly of P(DGMA-co-SMA)/THF/EtOH system. And spheral aggregates were obtained in P(DGMA-co-SMA)/THF/H_2O system while the spheral aggregates were converted into rod-liked aggregates and line-liked aggregates after aged for different time.

合成了带含环氧基侧链和十八烷基侧链的聚(马来酸二缩水甘油酯-co-甲基丙烯酸十八酯)，用~1H NMR对所得的共聚物进行了表征；研究了其在选择性溶剂中的自组装行为，发现P(DGMA-co-SMA)／THF／EtOH体系可以通过自组装形成囊泡形自组装体和支化的管状自组装体，P(DGMA-co-SMA)／THF／H_2O体系最初自组装形成球形自组装体，随着陈化时间的延长，球形自组装体逐渐融合成长条形自组装体和线形自组装体；探讨了自组装过程的机理，建立了可能的自组装过程模型。

The results showed that heat treatment had no obvious effect on main linkage way of the system. Between 500℃and 900℃, the crystal phase CaF_2 was precipitated firstly, with the rising of temperature and the prolonging of time, crystal phases such as Al_2SiO_5、Ca_2SiO_4 and Ca_3(PO_4)_2 were precipitated sequentially and the powder was changed from dispersive spheroidic to irregular strip that linked each other, and congregated to irregular mass, gradually.

热处理对体系的主体键连方式无明显影响；在500-900℃温度范围内，粉体优先析出CaF_2晶相，随着加热温度的升高及保温时间的延长，依次析出Al_2SiO_5、Ca_2SiO_4、Ca_3(PO_4)_2等晶相，粉体由分散的近球形颗粒转变成相互粘连的不规则带状，并逐渐聚合成不规则块状；固结体抗压强度逐渐增加后趋于平缓。

It was found that levels of IFN-γ and NO in splenocyte supernatants stimulated by PRBC or LPS from DBA/2 mice were remarkably higher than those of 1640 culture group,and they increased gradually with culture time.

结果表明以PRBC或LPS刺激后，DBA/2小鼠脾细胞上清液中IFN-γ和NO水平随培养时间的延长均有不同程度的提高，但BALB/c小鼠48h培养组的IFN-γ和NO水平仅比24h培养组略有升高。

Lift along with reaction temperature and the extension of time, in synthesizing child, miscellaneous photograph decreases, steatitic brilliant granuality increases Mg-Al water gradually.

随反应温度升高和时间的延长，合成产物中杂相减少，Mg-Al水滑石晶粒度逐渐增大。

In 30rain group, diminished or absent immunostaining cells appeared, but still located in subendocardial layer and papillary muscles.

到缺血4小时，心肌细胞则出现全层细胞的完全脱失并随着缺血时间的延长，脱失面积增大。

Results Lorcainide at concentration of 0.62mg/L,1.25mg/L and 2.50mg/L had a tendency of decreasing the incidence of arrhythmia during ischemia (P＞0.05),and at 1.25mg/L and 2.50mg/L significantly decreased incidence of arrhythmia during early reperfusion (P＜0.05).Its antiarrhythmic effect was accompanied with elevation of subendocardial threshold,significant abbreviation of action potential duratin in subendocardium and subepicardium,and complete or partly delay of transmural conduction time of pulses.

结果 劳卡胺分别在0.62mg/L、1.25mg/L及2.50mg/L剂量时使缺血性心律失常发生率轻度降低(P＞0.05)，后2种剂量使再灌注早期心律失常发生率明显降低(P＜0.05)；降低心律失常发生率同时可提高心内膜下心室肌兴奋阈，延长心内、外膜下心室肌细胞动作电位时程，延迟或部分延迟冲动跨壁传导时间。

Retinal neovascularizationincreasingly extended with the time of RRD,and developed into vitreousand subretinal space,no iris neovascularization was seen.

随着脱离时间的延长，新生血管范围逐渐扩大并长入玻璃体和视网膜下腔，未见虹膜新生血管。

So that the low temperature ion sulphurization technique can extend the service life of machine parts such as bearings, cutting tools, cylinder liners and piston rings of engine, gears, rollers, steel rings, etc.

渗氮＋渗硫复合处理可使渗硫层的持续时间显著延长，并能在各种速度条件下非常明显地提高表面的抗擦伤性能。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
