To better establish relationship between spectra and efficiency, the efficacy part of corals and sponges were taken, active parts studied. NMR techniques and multivariate statistical analysis were used. Data showed that separation of active parts was reasonable and effective. ~HNMR samples of coral and sponge samples of active parts were systematically identified. This work provides technical foundation and basis for spectroscopic follow-up studies.

Here,the spectral characteristics of(E)-3,5,4'-Trihydroxystibene were analyzed, using NMR experimental techniques including !H NMR,APT(Attached Proton Test), HMBC and etc.The structure of the testing compound is not complex,but it is highly Symmetrical and contains a relatively few number of protons.This would cause troublesome to the NMR structural illustration.In this work,the correlation information was exposed from the experimental spectra,the spectral characteristics including some "artifacts" were explained.Finally,the structure of the testing compound was provided reasonably.

The interaction of human serum albumin and folic acid was studied using fluorescence spectroscopy, UV absorption and synchronous fluorescence spectroscopy in the pH 7.4 Tris-HCl buffer system at different temperatures. The research shows that these interactions result in the endogenous fluorescence quenching of HSA, which belongs to a static quenching mechanism. The quenching rate constants, the binding constants and the binding sites of the static quenching were calculated. The distance between the body (HSA) and receptor (folic acid) and the efficiency of energy transfer were obtained to be 1.77 nm and 0. 052 65 respectively, based on the theory of Forster nonradiative energy transfer. And according to the thermodynamic parameters calculated the binding of HSA and folic acid is mainly attributed to the hydrophobic interaction, partly static force. Further more the synchronous fluorescence spectrum was utilized to investigate the conformational transformation; The decline result of the hydrophobic nature around Trp demonstrates that the folic acid is in the hydrophobic cavity of HSA.

200 college students′ cognition of the necessary ability of mental health were investigated by interviewing, and a model was set up to show the configuration of the cognition. What highlighted on were as follows:(1)the college students′ cognition of the necessary ability of mental health was built up by self-regulation, learning, social problem-solving and social interaction;(2)the four aspects were independent but correlative.

175 graders from 3 to 6 were selected from one primary school to explored that if and how the cognitive load influenced the strategies selection of pupils' distributing working memory resources in solving the running- arithmetic problems. The results showed: Intrinsic cognitive load did influence the strategies selection of pupils' distributing working memory resources. In the strategies selection, cognitive load effected the cognitive performance, but for the lower graders the effect is not remarkable. For the sixth graders, the effect is remarkable. In the accuracy of the strategies, the effect of cognitive load reduced by the grades. And in the efficiency of the strategies, cognitive load did influence the strategies.

175 pupils(3,4,5 and 6 grades respectively)were sampled from a primary school to explore the strategies of pupils' distributing working memory resources in solving running-arithmetic problems.The results showed: The strategies of pupils' distributing working memory resources were multiple. There were at least eleven strategies which subjects used for distributing working memory. Strategies differed in aspects of accuracy and solution time.The external strategy is superior to the internal strategy and the associative strategy of internal and external. Strategies used were quite different in solution time. Higher graders were more likely to select more efficient strategies than lower graders.

以初一到高三274名中学生为被试,以连环数认知运算为实验材料,对中学生工作记忆资源的分配策略进行了考察,结果表明:中学生工作记忆资源的分配存在多种策略,且具有多样性;外部策略的正确性高于内部策略和内外部结合策略;中学生使用不同策略解决问题的反应时差异显著;以学生的策略选择的百分比和策略的正确率与解题速度为指标综合考察学生的策略选择来看,中学生较倾向于选择正确率较高的策略.

Objective: The current study was conducted to explore the features of ill-emotion of primary pupils. Methods:3,315 pupils from grade three to six were sampled from three different regions all over the country,and their anxiety, depression, loneliness, hostility and fear were examined. Some related statistics were conducted. Results: There were differences between regions and grades in ill-emotion of primary pupils. Conclusion: The emotion state of participants was quite good.

对24名7～18岁的儿童青少年进行脑电图记录,比较其在静息状态和记忆状态下脑电α波特点.结果表明:1)记忆状态下被试α波分布的熵值明显升高;2)记忆状态下α波平均频率显著上升;3)记忆状态下11,12,13Hz等高频脑波所占比率显著上升;4)高频脑波所占比率的上升在前脑和左脑更加明显.

用ET技术对24名7-18岁的儿童青少年进行了静息状态和记忆状态下脑电超慢涨落特点的比较研究,结果表明,在记忆状态下:(1)被试S1、S2频率明显下降,记忆成绩好的被试这一特点更为明显;(2)男生左脑功率明显下降,女生右脑功率明显上升;(3)左脑优势被试左前脑功率下降,右脑优势被试右前脑功率上升.

采用问卷法对北京、新疆、重庆、浙江、河南共6015名高中生的不良情绪状态进行了研究。结果表明，高中生的焦虑、抑郁、孤独、敌对、恐惧等五种不良情绪的状态均处于中等程度，随着年龄的增长，高中生不良情绪的这五个方面表现出较为一致的变化特点：随着年龄的增长，其不良情绪的状态呈缓慢上升的变化趋势，高二学生的抑郁、孤独、敌对、恐惧等不良情绪状态显著高于高一学生；高三学生的五种不良情绪状态均略高于高二学生，但是来达显著性水平，高中阶段的五种不良情绪未出现显著的性别差异。
