The catalysing system has higher stability both in resin solution storage and in heat-resistance.

叔胺类催化剂的加入能加快体系的共聚和固化过程，提高树脂溶液的贮存稳定性和固化树脂的热稳定性。

MethodsDross were purged from Luohanguo extract with water by ZTC1+1 clarifier, mogroside were isolated by D101 macroporous resin, decoloured on a D301R weak alkaline ion exchange resin.

方法用ZTC1+1澄清剂除去罗汉果水提液中的杂质，以D101大孔吸附树脂分离罗汉果甜苷，D301R弱碱性离子交换树脂脱色。

ResultsD101 and HPD-100 resins had good property to absorb and desorb TFG.

结果D101和HPD-100大孔吸附树脂对红凤菜总黄酮具有良好的吸附分离性能，吸附快、解吸附容易，性能优于其他树脂。

When 4％ NaOH, which is three times volume of the resin, is selected as the desorbent, the flow rate is 1BV/h and the temperature is 60℃, over 99. 7％ phenol on the resin can be desorbed and the recovery is more than 95％.

用3倍树脂体积、温度为60℃的4％NaOH溶液作解吸剂，控制1BV/h的解吸液流速，可使树脂的解吸率在99.7％以上，95％以上的苯酚得以回收。

Seventeen resins were selected to compare their performances in adsorbing and desorbing monosubstituent in the mixture. Experimental results showed that HZ-841 resin possessed higher selectivity and desorption capacity.

比较了17种树脂对β-环糊精单甲苯磺酰化产物的吸附特性，确定了大孔弱极性吸附树脂HZ-841对单取代物具有较高的吸附选择性和良好的脱附性能。

This thesis focuses on the photosensitive complexes from diazo resin and phenolic resin and layer-by-layer self-assembly multilayer films based on DR.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
