Transformation into active enzymes occurs as one or more peptide bonds in the zymogen are cleaved.

活化作用即是打断原分子内的一个或多个键。这作用受不同的催化或受的活化型本身的催化。

SEM and TEM observations indicate that the prior austenite deformation not only refines the allotriomorphic ferrite grain but also promotes the nucleation of intragranular ferrite, both of which in turn contribute to the refinement of granular bainite cluster including its ferrite platelets and MA islands.

SEM和TEM观察表明，奥氏体形变不仅细化仿晶界型铁素体，而且促进先共析铁素体在原奥氏体晶内形核，从而有利于细化粒状贝氏体晶团及其内部的铁素体片条和MA岛。

Accelerated cooling (60℃/s) to 400℃ refines the allotriomorphic ferrite grain but retards the nucleation of intragranular ferrite with its distribution on prior austenite grain boundary as well as the volume fraction of bainite increased, and the strength increased but the elongation decreased and yield ratio became much higher on the steel.

当冷速增加到60℃/s且卷取温度为400℃左右时，铁素体在晶内形核受到抑制，铁素体沿原奥氏体晶界分布，晶粒得到细化，贝氏体体积分数增加，强度有较大的提高，但延伸率较低，屈强比较高。

Results In model group, alveolitis increases (much inflammatory cell infiltration), pulmonary interstitial fibroblast increases.

结果］模型组7d时肺泡腔内大量炎性细胞浸润，可见少量成纤维细胞，Ⅰ型细胞受损，Ⅱ型细胞明显增生；28d时肺泡炎减轻，肺间质和胸膜层胶原纤维明显增多。

These results suggested that the lung Fib were activated and produced excess HA, resulting in the excessive accumulation of HA within the lung at the stage of alveolitis during the process of pulmonary fibrosis. However, increased HA synthesis of lung Fib and increased HA levels in BALF merely reflect the intensity of alveolitis and the disease activity rather than the degree of pulmonary fibrosis.

以上结果提示：肺Fib在肺纤维化的早期肺泡炎阶段就处于活化状态，产生HA增多，导致肺内HA的过多聚积，肺Fib产生HA增多和BALF中HA水平的增高可反映肺泡炎的强度和疾病的活动性，但并不能反映肺胶原代谢或纤维化的程度。

After the carboxymethylation,the solubility of pachyman in the water was significantly increased,its β-D-glucan characteristic absorption peak at 890 cm-1 became weak obviously,and its methylene vibration absorption peak and CO antisymmetrical stretch vibration absorption peak appeared at 1 333 and 1 606 cm-1 respectively,which indicated that the carboxymethylation succeeded.The analysis of AFM results showed that CMP molecules existed in different morphology under different solution conditions,and that the concentration,ionic strength and solvent physical chemistry characteristics of polysaccharide solution had effects on the CMP chains conformation and the action mode between different molecular chains.The phenomena were considered to be related to hydrogen bond association and intramolecular and intermolecular electrostatic interactions of CMP.

结果表明：经过羧甲基修饰，茯苓多糖在水中的溶解性显著增加，890 cm-1 处的β-D-葡聚糖特征吸收峰明显减弱，1 333 cm-1 处出现次甲基振动吸收峰，1 606 cm-1 处出现〖JG(〗C〖ZJLX，Y〗O〖JG)〗非对称伸缩振动吸收峰，表明羧甲基化成功；原子力显微镜分析表明：在不同溶液条件下，CMP分子以不同形态存在，多糖溶液的浓度、离子强度及溶剂的物化特性均能对CMP的分子链构象及链间相互作用形式产生影响，推测可能与CMP分子内、分子间的氢键缔合及静电作用有关，CMP分子与云母基底间的吸附及静电作用也会对CMP的分子链构象及图像质量产生影响。
