通过在聚酰亚胺的主链中引入庞大侧基（9，9-二苯基芴）形成轴状聚酰亚胺，同时提高聚酰亚胺的溶解性和热稳定性；庞大的侧基又能阻止链的堆砌，避免生色团荧光链间淬灭；通过加入第二种二酐单体合成三元缩聚型聚酰亚胺，调控荧光性二酐在聚酰亚胺中的含量，降低生色团在聚酰亚胺中的浓度，来避免生色团荧光浓度淬灭，增加聚酰亚胺的固态荧光量子效率；通过使用热稳定性好的稠环生色团苝和吖啶来避免共轭类生色团（如含双键或三键的生色团）在高温下热交联及氧和水的破坏。

The results showed with the increasing of NaCl concentration, the phenomenon of carnification could be found in the leaves of Arabidopsis thaliana . Under the stress of NaCl lower than 100 mmol/L, the tissue structure of root had no distinct difference from the control. When the concentration of NaCl was higher than 250 mmol/L, the stained color of safranine was deep but not even, and color in fibrovascular tissue and peripheral cortex cell were deeper than that around fibrovascular tissue.

当NaCl浓度小于100 mmol／L时，根组织结构与对照未表现出明显的差异；但当NaCl浓度达到250 mmol／L时，根组织结构对番红染料的着色较深而且不均匀，维管组织和外围皮层细胞着色较深，而维管组织周围的细胞着色较浅。

The result showed that the biomass, plant height, dry weigh, carnification, K(superscript +) content and K(superscript +)/Na(superscript +) ratios of I. lactea var. chinensis decreased with increasing NaCl stress, while root/shoot ratios and Na(superscript +) content increased. The water content and carnification degree of roots in all treatments were higher than shoots, which, however, was not significantly related to salt concentration.

试验结果表明：在NaCl胁迫下，随著胁迫浓度的增加，马蔺生物量、株高、干重、肉质化以及K含量、K/Na比值降低，同时根冠比、Na含量增加：各盐处理区根系含水量和肉质化程度大於茎叶，但与盐浓度的相关性不大。

Calcium alginate gels. So, the concentration of calcium solution may increase to 300 mmol/L, which has no influence on the growth of cartilage cell, and can enhance the intensity of calcium alginate gels.

因此固化剂氯化钙的浓度可以提高到300 mmol/L，该浓度不仅对软骨细胞的生长无影响，而且能适当提高藻酸钙凝胶的机械强度，可以作为一种较理想的软骨组织工程支架材料。

Vase-life of gerbera flowers was extended by addition of either 50 or 100mgL-1 carvacrol and either 1 or 2mgL-1 SNP from 8.3 to 16d.

非洲菊的瓶插寿命可通过添加进浓度为50或100mg/L的香芹酚或者浓度为1或2mg/L、介于8.3至16级别的SNP溶液来得到延长。

The method for direct preparation of sodium caseinate from Qula was iwestigated, soaking and washing conditions were studied and compared, Analysis on factors influencing test such as material concentration, washing times, soak temperature and soak time was carried out.

采用曲拉直接浸洗法制取酪朊酸钠，进行浸洗工艺条件研究比较，对原料浓度、水洗次数、浸泡温度、浸泡时间等影响因素进行试验分析，确定最佳工艺条件为：原料浓度11%，浸泡温度45℃，浸泡时间3.5h，水洗3次，最终产品乳糖含量为0.35%。

Less amount of essence if used in floral water, about 5 percent (including 5%), a large amount of alcohol is used, but the density is low and a small amount of cassia oil needs to be added, herba agastachis oil and other raw materials need to be added, a large amount (over 5%) of essence is needed for perfume, less alcohol is used, but the density is high.

花露水香精用量少，在5％（含5％）以下，酒精用量多，但浓度低，且要加入少量桂皮油、藿香油等原料；香水香精用量大，在5％以上，酒精用量少，但浓度高。

Because of the effect of catabolite repression and synergistic mechanism between pructs, the degradation of succinonitrile is promoted while the degradation of alkanes is inhibited in the mixed system of culture medium.

废水中烷烃质量浓度低，烷烃降解菌不能发挥其高效的降解作用，丁二腈质量浓度较大，降解效果明显，9h降解率可达到100%；腈纶废水经混合菌9h处理后，田氏去除率仅为29%，说明实际废水是个很复杂的体系，仅依靠个别高效菌株难以达到理想的整体处理效果，必须构建更多种类的具有协同作用的高效菌群，才能在实际应用中取得满意的结果。
