Compared with other methods, the effect on preservation of the cut flowers, pretreated in 100 ml/L benzalkonium bromide for 3 hours, was obvious. The fresh flower weights increased slowly, few or none leaves were wilting after transplanted into water for 6 days. Etiolation of the leave slowed down and almost 90% leaves kept fresh after 12 days. The flower buds blooming speed also slowed down, 50% of flower buds were opened, petals were kept fresh, the stems of cut flower were unbent, and none flowers were drooped after 15 days.

与其他预处理相比，在100 ml/L溶液预处理3h，瓶插后鲜重一直呈缓慢上升趋势；6d后，极少数叶片发生萎蔫，叶片黄化速度也很缓慢，约90％的叶片12d后还可以保持新鲜；花蕾开放速度也缓慢，15d后仅有50％的花蕾开花，且花瓣挺阔，无枯萎迹象，而且茎干挺直，不弯颈；保鲜效果明显高于其他的预处理。

To examinate the thermal properties by TGA、DSC and figure out the maximum decompose temperature which survey the range of liquid crystal temperature. We synthesize conjugated polymer successfully and these emitted blue fluorescence. Hope this experiments will supply well-contribution in field of organic light-emitting diodes.

以TGA、DSC测定其热性质，并了解到由TGA的5%热重损失温度再进行测出液晶温度范围，我们成功的合成出具有良好的加工性的共轭性分子，发光性质都出现在蓝光领域，愿在有机发光二极体的领域上有重大的贡献。

Besides, Dalian has been being an important industrial city of our country since 1930's. Both heavy-duty and handiwork industrials are located here, such as machinery, metallurgy, ship manufacture and salt process, shell glyptic and so on.

作为东北老工业基地，大连一直都是我国重要的工业城市，聚集了大量的机械、冶金及船舶制造等重化工业，以及海盐加工、贝雕等手工制品业，而且历史悠久，其中不少规模庞大的厂矿都是在日俄侵占时期开办的，极具社会历史文化价值。

The results of the experiment indicated that the average body weight of gosling and daily gain were higher significantly in low energy treatment than in high energy treatment (P.01), and under a certain level of energy, body weight and daily gain went up with the increasing of the level of protein and feed conversion ratio was improved.

本次试验表明低能组的平均体重和日增重要极显著的高于高能组(P＜0.01)，在能量水平一定的条件下，体重、日增重随着蛋白质水平的提高而提高，同时料肉比也得到一定程度的改善。

The influence of mechanical activation on the crystal structure and leaching behavior of hemimorphite was investigated by SEM, particle distribution analysis, TG-DSC analysis and XRD analysis.

通过浸出动力学实验、扫描电镜分析、粒度分析、热重－差热分析、X射线衍射分析探讨机械活化对异极矿晶体结构和浸出行为影响的规律。

Ceramics and soldering iron. With white and blue porcelain and powder colors, Wu created the nonobjective half-length statue, bright and vivid in color. Through repeated application of symbols in Chinese traditional ceramics, the ornaments on the household wares were finally turned into a cultural symbol of extremely simplified human figures. That is how Wu handled the transformation from traditional to modern.

青花和粉彩的近乎抽象的陶瓷半身人像，被赋予鲜艳的色彩，传统陶瓷提炼的符号不断重复，从附着于器物用品的装饰转而成为极简的现代人形的文化符号特征，完成了现代与传统的对话，是颠覆也是重生。
