So the present study was taken to compare the differences in the mechanisms of dissipating excess light energy in cucurbit crops and to study the differences in both the ROS metabolism in root system and the photosynthesis among six cucurbit crops with different temperature tolerance growing at different root-temperatures. The main results are as follows: 1、The species specific response of three cucurbit crops with different heat-tolerance: warm-adapted cucumber, heat-tolerant sponge gourd and heat-sensitive figleaf gourd to diurnal changes in air temperature and irradiance intensity were investigated in a typical summer sunny day. Three cucurbit species were compared using parameters in gas exchange, chlorophyll fluorenscence, photon allocation and photosynthetic electron flux.

因此，本试验以温度敏感性不同的瓜类作物为材料，研究了夏季自然条件下不同物种间在耗散过量光能的主要机制差异；探讨了它们对不同根际温度在根系活性氧代谢及地上部光合作用等方面的生理响应差异，所取得的主要结果如下： 1、在夏季晴天条件下，三种温度敏感性不同的瓜类作物：喜温的黄瓜，耐热性的丝瓜与热敏感的黑籽南瓜在气体交换、叶绿素荧光、光能分配及光合电子流对一天中温度与光照环境变化的响应上存在物种间差异和日变化特征。

Therefore, an un-derstanding of the maintenance of the stationary waves is a prereq-uisite for a thorough understanding of the low frequency transients.The Eliassen-Palm cross-section and the three-dimensional waveactivity flux, which was derived by Plumb (1985) for the linear quasi-geostrophic stationary waves in a zonal flow, are ...

分析结果表明，Plumb通量和EP剖面图，不仅可以用来诊断波作用在三维空间的传播、波动与纬向平均气流之间的相互作用，而且也可以用来诊断非线性作用的显著性，在利用它们对于观测资料进行诊断分析时，应当充分注意到非线性作用的影响。

The variations of machine parameters, due to operation temperature, saturation level of rotor flux , rotor time constant, etc., lead to poor dynamic performance and incorrect stationary point of operation.

由于系统运行过程中的温升、磁饱和等因素会导致电机的参数发生变化，参数变化势必会影响拖动系统的动态性能并且可能会导致系统的不稳定运行。

The error in magnitude of the stator flux is 1 if it is two low and 0 otherwise.

错误严重的，如果定子流量120低的。

Direct torque control has excellent dynamic performance, but it has large ripple on stator flux and electromagnetic torque.

It is suggested that TDS can be used as a new method for the analysis of pedogenesis and climatic change.

总之，热处理过程中磁化率的变化能非常灵敏地反映磁性矿物的转化情况，而且，这种转化往往与样品所经历的土壤化作用强度密切相关，因此，TDS可做为分析成土作用强度和古气候变化的一种新方法。

Therefore, in this chapter, I will research into the conflict and contradiction of the paternity. Also, in this novel, the father's behavior of "He who loves well chastises well." is quite suspicious, one of the reasons is that the father thought his son belonged to him. And then, this thesis quoted Lacan's theory to touch upon that someone who has accepted the concept of patriarchal society, he will be influenced for his whole life. That also reveals that human being has no choice sometimes in this society.

因此本章会先就父子关系的冲突与矛盾做深入的探讨，小说中的父亲似有对儿子爱之深责之切的行为，其原因可能在於父亲将儿子视为所有物所致；其次，论文将引用拉冈相关理论，讨论在父权社会中，不论身分为何，只要是已受父权社会观念根深蒂固影响的人物，终生都将受其所苦，此也揭示出人生存於社会上的无奈。
