One of the main clinical characteristics is the decreased protein synthesis with increased proteolysis.

氧化应激是机体氧化产物超过机体抗氧化防御能力一种应激状态，可以导致细胞、组织和器官的损伤。

Effects of Psoralea corylifolia L.extract on the defensive enzymes on cucumber were studied and the results showed that activities of peroxidase,polyphenol oxidase, phenylalanine ammonialyaseof cucumber leaves were increased to highest level after 7 to 9 days at 40 mg/L and 400 mg/L.

补骨脂粗提物处理两叶一心生长期的黄瓜幼苗，补骨脂提取物在40mg/L和400mg/L浓度下，黄瓜体内过氧化物酶、多酚氧化酶、苯丙氨酸解氨酶等一些防御酶活性均在处理后7d～9d达最高。

Forβ-l,3-glucanase,its activity increased to peak level after 2 to 5 days and was 2.02 and 1.34 folds of check,then decreased rapidly and resumed to normal level after 5 and 9 days.Generally Psoralea corylifolia L.extract may enhance the activities of chitinase andβ-l,3-glucanase in cucumber leaves,then induce the enhancement of activities of defensive enzymes.

从所测定的几种酶活性变化时间来看，补骨脂提取物处理黄瓜幼苗后，首先，使黄瓜体内的几丁质酶和β-1，3-葡聚糖酶等病程相关蛋白活性升高，然后在两者的作用下，诱导了黄瓜体内过氧化物酶、多酚氧化酶、苯丙氨酸解氨酶等一些防御酶活性的提高。

Objective To explore the relation between delusion and defense mechanism of schizophrenics in a psychodynamic view.

目的 从精神动力学角度探讨精神分裂症患者的妄想与心理防御机制的相互关系，为临床心理治疗和康复训练提供理论指导。

"We have identified some fortification walls with gates on the inland side of Korphos-Kalamianos, which does suggest that the town had at least some role as a fortress, possibly to protect the harbor," Pullen said.

Instead of being confined within the walls of fortified cities, which the Romans considered as the refuge of weakness or pusillanimity, the legions were encamped on the banks of the great rivers, and along the frontiers of the barbarians.

罗马军团不在防御坚固的城镇中驻扎，——罗马人认为城堡是软弱和怯懦的庇护所，——而是通常在大河的沿岸扎营，紧邻着野蛮人的边界。

The strong local loyalties which had been a positive feature of the Commune now became something of a disadvantage: instead of an overall planned defence, each "quartier" fought desperately for its survival, and each was overcome in turn.

很强的本地忠诚度在过去曾是公社的一个有利因素，现在却变成了某种不利：没有一个统一的有计划的防御，每个街区为了自己的生存各自为战，最后被一个接一个地攻破。

The application of queuing theory in the calculation of penetration probability of defence system is analyzed.

系统分析了排队论在防御系统的突防概率计算方面的应用，指出了它的局限性和存在的问题。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
