心理治疗还是药物治疗

心理治疗与药物治疗是精神病领域的两种治疗模式。心理治疗模式认为，个体精神状况正常与否主要受情绪、人格等心理因素影响，精神疾病由后天环境和生活经历所致；药物治疗模式则认为，精神病及各类神经症都有其生理基础，大脑机能的缺陷是导致精神疾病的主要原因，因此主张用药物进行治疗。尽管两者在精神病治疗中都有自己的优势与不足，但是在科学一统天下的今天，生物学模式似乎成了治疗的主流。要想最终解决心理治疗与药物治疗之争，科学预测精神病治疗的未来及新世纪心理治疗的命运，必须首先解决：（1）心理学的学科体系问题；（2）精神疾病的界定问题以及（3）心身关系问题。

再辉效应对T9A钢显微组织和机械性能的影响

研究了T9A钢铅浴淬火时,再辉效应对其显微组织和机械性能的影响.在珠光体转变温度范围内等温时,随着等温温度的降低,引起塑性下降的原因是再辉效应促发颗粒状或短片状珠光体形成;在上贝氏体转变温度区,由于出现再辉效应产生的温度爬升现象,使试样温度升至屈氏体转变温度区从而形成上贝氏体和屈氏体的混合组织,使得强度增高曲线出现平台或稍有下降,且塑性发生下降,同时,还对等温淬火的定义提出了新的看法,绘出了反映实际情况的共析钢C-曲线上的组织形成图。     

大学生口算能力的实验研究

为考察大学生的口算能力,我们随机选取30名大学生为被试进行口算的实验研究,主要结论如下:(1)大学生的口算速率在加、减、乘、除法之间存在差异,从快到慢依次为:除法,借位减法,不借位减法,不进位加法,进位加法,乘法;(2)口算的广度从大到小依次为:不进位的加法广度,进位加法广度,不借位减法广度,借位减法广度,除法广度,乘法广度;(3)大学生口算的速度和广度既无显著的专业差异,也无显著的性别差异.     

Experimental Observables on Nuclear Liquid Gas Phase Transition

Progress on nuclear liquid gas phase transition （LGPT） or critical behavior has been simply reviewed and some signals of LGPT in heavy ion collisions, especially in NIMROD data, are focused. These signals include the power-law charge distribution, the largest fluctuation of the fragment observables, the nuclear Zipf law, caloric curve and critical exponent analysis etc.     

Theoretical study on the lithium bond interaction of furan homologues C_4H_4Y (Y=O, S) with LiCH_3 via DFT and MP2

The optimizations geometries and interaction energy corrected by BSSE of the complexes between C4H4Y (Y=O, S) and CH3Li have been calculated at the B3LYP/6-311 G** and MP2/6-311 G** levels. Three complexes were obtained. Abnormally, the calculations showed that all the C10—Li14 bond lengths increased obviously but the blue-shift of C10—Li14 stretching frequency occurred after formed complexes. The calculated binding energy with basis set super-position error (BSSE) and zero-point vibrational energy corrections of complexes I―III is ?45.757, ?35.700 and ?39.107 kJ·mol?1, respectively. The analyses on the combining interaction with the atom-in-molecules theory (AIM) also showed that a relatively strong lithium bond interaction presented in furan homologues C4H4Y---LiCH3 systems. Natural bond orbital theory (NBO) analysis has been performed, and the results revealed that the com- plex I is formed with n-σ type lithium bond interaction between C4H4O and LiCH3, complex II is formed with π-s type lithium bond interaction between C4H4O and LiCH3, and complex III is formed with π-s and n-s type lithium bond interactions between C4H4S and LiCH3, respectively.

Solid-state Synthesis of Carbon-nanostructures

1 Results In addition to single wall and multiwall carbon nanotubes[1], several structures,which are more or less related to fullerenes,including carbon nanohorns[2a], carbon nanospheres[2b] and onion like carbon structures[2c] have been reported.A new simple straight forward method to access some of these structures is the solid-state pyrolysis of different organometallic complexes in a sealed vessel,which led so far to carbon nanotubes[3a,b], carbon nanocables[3c] and onions[3d].     

Applications of Transition Metals in Organic Synthesis and Polymerization

1 Results Classic oxidants require rigorous control of the experimental conditions added with the problem of lack of selectivity. Catalysis by transition metals with environmentally safe oxidants provides synthetic routes to minimize pollution by giving environmental benign by-products. Fe (Ⅵ) is a powerful and a selective oxidant with Fe(Ⅲ) as a by-product, while hydrogen peroxide is clean with water as the only by-product. Separation of sodium or potassium ferrates requires tedious processes. Associat...
