In particular, it is unknown how the relevant neural substrates function as a network to mediate perspective-taking during the task requiring understanding other's belief. The current work first developed a new psychological paradigm that excludes potential confounds such as the processing of language, biological motion, episodic memory and causal coherence in the paradigms used in previous studies. I recorded neural activities associated with mental inference task using functional magnetic resonance imaging and electroencephalography in order to investigate the functional roles of several brain areas (i.e. precuneus, MPFC, etc.) that engage in understanding other's belief. I also proposed a computational model based on the neuroimaging results that simulated the neurocognitive mechanism underlying cortical dynamics in correct judgment of other's belief.

The reseach on activity changes of SOD, POD and CAT during the somatic embryogenesis of Y35 showed:(1) The activty of SOD was from 52.98 to 133.20 U·g-1·h-1, and remained a rising trend after early single embryo forming, this revealed that SOD might be positively correlated to the differentiation of embryogenic cell and the development of somatic embryo.(2) The activty of POD was from 0.05 to 0.50 U·mg-1·min-1, ascended firstly and desceded later, and was highest in embryogenic callus and lowest in late single embryo , this revealed that POD might be positively correlated to the division and differentiation of proembryo mass, while negatively correlated to the development of PEMⅢto late single embryo.(3) The activty of CAT was from 0.86 to 2.81 U·mg-1·min-1, showed an up-down-up trend, reaching to the highest peak at the time of early embryo formating and decreasing to the lowest at the time of early cotyledonary embryo formating, this revealed that CAT might be positively correlated to the development of early single embryo, while negatively correlated to the formation of middle single embryo and early cotyledonary embryo.The changes in activty of SOD, POD and CAT indicated these three antioxidant enzymes coregulated the differentiation and development of embryogenic cells during Larix somatic embryogenesis.4. Differentially expressed cDNA libraries of the stages of proembryo mass and somatic embryo maturation were successfully constructed by suppression subtractive hybridization.

The normally brominated Baylis-Hillman adducts were formed as the major product at low temperature. While at room temperature or heating, the α,γand β,β-dibrominated compounds were formed as the major products using 3-butyn-2-one and methyl propiolate or propynenitrile as substrate, respectively.

第三，我们用生物化学方法，选取海洋中广泛存在、众多水产动物的常见致病菌-溶藻弧菌作为天然反应原感染文昌鱼，从另外一个角度探讨并丰富文昌鱼体液中的八种炎性蛋白的急性时相反应，结果显示，与LPS感染文昌鱼相比，六种正APPs的浓度变化幅度相对较小，曲线相对平缓，但仍然呈正急性时相反应，蛋白电泳也证实了这一点；而二种负APPs：RBP和白蛋白(Albumin，ALB)浓度实验周期内总体呈下降的趋势，呈负急性时相反应，结论与上述LPS相同。

The square wave or corrected sine wave auto inverters have many limitations. When supplying to inductive load (such as electric fan, electric drill etc.), a square wave or corrected sine wave auto inverter produces too much harmonic current which makes the load seriously heated and even damaged. When supplying to capacitive load or rectificative load such as notebook PC, mobile phone charger etc.

But in practical operating, overvoltage caused by reignition of the vacuum switching device frequently appears, and it result in damage of the capacitor bank or the switchgear itself. Ensuring the switchgear against reignition and installing a protective device are two main approaches to avoid the phenomenon. In this paper, a study on overvoltage caused by reignition due to capacitor bank switching with the vacuum switching device and its preventive measures are carried out. The main work which has been done and researches are as follows: 1. The producing mechanism of overvoltage and its influence factor are analyzed. It is pointed out that single-phase reignition is the main reason for damage of the switchgear and two-phase reignition is the main reason for damage of the capacitor bank,so overvoltage of single-phase reignition and two-phase reignition are the emphases of prevention. 2. Analysis of the special working condition of the operating switch for capacitor bank is carried out. It indicates that the vacuum switching device is difficult to realize no-reignition under this operation condition, so it is more practical to adopt protection devices. 3. Analyses of protection effect of RC and MOA and their shortages are carried out. It shows that the two methods can only restrain effectively overvoltage caused by single-phase reignition, and they cannot protect the capacitor bank when reignition of two-phase occurs. 4. The operation principle of G-R damping device is analyzed and discussed emphatically.

本文针对真空开关投切电容器组时因重燃而产生的过电压及其防治措施进行了研究，所开展的主要工作和研究结果如下： 1、对过电压的产生机理及其影响因素进行了分析，指出单相重燃是导致开关设备损坏的主要原因，而两相重燃则是导致电容器组损坏的主要原因，因此单相重燃和两相重燃过电压是防护的重点； 2、对电容器组操作开关的特殊运行条件进行了分析，指出在这种运行条件真空开关难于实现不重燃，因此采用保护装置更具有现实意义； 3、对RC与MOA的保护效果和存在的不足进行了分析，指出这两种方法均只能有效抑制单相重燃过电压，而不能在发生两相重燃时保护电容器组； 4、重点对G-R阻尼装置的工作原理进行了分析和讨论，指出该装置接入后线路中将会出现两种频率的高频振荡，而电容器组上的过电压是由这两种振荡共同决定的； 5、根据对上述两种振荡的分析指出存在一个最佳电阻值使得过电压最低，并提出了电容器组电压和最佳电阻值的近似求解方法； 6、使用电气暂态分析软件MATLAB对G-R装置的保护效果进行了仿真计算，证实该装置确实可以有效抑制重燃时的电容器组过电压； 7、根据仿真与近似计算结果的偏差提出了近似计算的修正方法，经过修正后的过电压计算结果与仿真结果吻合较好； 8、对G-R装置中放电装置G与阻尼电阻R的要求进行了分析，指出采用编织电阻和真空间隙可能是最佳选择。
