Three-dimensional(3D) electrode technology is a competitive water treatment technology owing to its high catalytic efficiency, low energy consumption, and promising development. The introduction of a third electrode on the basis of a 2D electrode system forms a 3D electrode system, and the introduced third electrode is also known as the particle electrode. Particle electrodes in3D electrode system are generally in the form of particles or crumbs that be filled in between the cathode and anode. The core of the3D electrode system is the particle electrode, so the selection of particle electrode materials is the focus of the research of 3D electrode technology. Carbon-based materials are widely used as particle electrodes in 3D electrode technology because of their advantages of large specific surface area, good adsorption performance, high chemical stability, and low price. In this review, the research progress of carbon-based materials as particle electrodes for degrading organic pollutants in recent years is collected, the principle of3D electrode technology is introduced, along with the classification of particle electrodes and the current research status of carbonbased particle electrodes, and the challenges and future development of carbon-based particle electrodes in wastewater treatment are summarized.

Onion-like Fullerenes were produced at high-temperature in vacuum. The morphology of the carbon nano onion-like fullerenes was examined and characterized by high-resolution transmission electron microscopy (HRTEM). It can be seen that the nano-sized, onion-like fullerenes possess high degree of graphization. The results suggested that the catalyst is the main factor affecting the size and yield of the fullerenes. The method is very promising for simple mass production.

Rice plants would more frequently suffer from high temperature (HT) stress at the grain-filling stage in future. A japonica rice variety Koshihikari and an indica rice variety IR72 were used to study the effect of high temperature on dynamic changes of glutamine synthetase (GS) activity, glutamate synthase (GOGAT) activity, glutamic oxalo-acetic transminase (GOT) activity, glutamate pyruvate transminase (GPT) activity in grains and grain nutritional quality at the grain-filling stage. Under HT, the activities of GOGAT, GOT, GPT and soluble protein content in grains significantly increased, whereas GS activity significantly decreased at the grain-filling stage. In addition to the increase of protein and amino acids contents, it was suggested that GOGAT, GOT and GPT in grains played important roles in nitrogen metabolism at the grain-filling stage. Since the decrease of GS activity in grains did not influence the accumulations of amino acids and protein, it is implied that GS might not be the key enzyme in regulating glutamine content in grains.

以三氧化铬(CrO_3)与石墨为原料,利用真空热处理方法制备了三氧化二铬(Cr_2O_3)石墨的插层化合物(GICs)。运用X射线衍射(XRD)分析石墨插层化合物。结果表明:经热处理后,在1400℃时CrO_3与石墨形成了纯5阶的石墨的插层化合物。XRD分析表明,对网状层面结构的天然石墨,可以利用物理的方法使一些非碳反应物(原子、分子、离子、或粒子团)插入石墨层间,从而改变石墨的层面结构,使产物出现新的物理性质和化学性质。X射线光电子能谱(XPS)分析和表征了Cr离子以3价的形式存在于石墨插层化合物中。

Aimed at the deficiency of the mechanism of management and consultation, an idea of an internet-based Virtual Diagnosis Center （VDC） for machine fault is proposed, and the key elements of remote consultation are abstracted. Around the key elements, the construct scheme and cooperative mechanism among experts of VDC are designed. According to the diagnosed object, the context knowledge of a fault machine, fault cases and ActiveX-based analysis tools are integrated into a multimedia consultation environment in VDC to enhance the efficiency of expert consultation. Simultaneously, the technique of push subscription in a SQL Server is utilized to collect machine condition data in an enter- prise machine condition database, which ensures the security of the database. The VDC system in Xi＇an Jiaotong University has been applied to remote diagnosis of a blower in Wuhan Iron and Steel Corporation and the system construction reasonableness and the running stability are verified.

众所周知受精是物种繁衍的重要一步。不同于具有体内受精特性的物种，很多海洋无脊椎生物直接将精卵排放到自然水体中，不具有复杂的交配行为，不存在生物个体水平上的性选择（Sexual selection），其受精率主要依赖于水中精卵的相互作用。在理想状态下从生物物理学角度考虑，具有生殖细胞自由排放（Free—spawning）特性的水生生物，其生殖细胞在受精过程前散布于三维立体空间内，

在我们的日常审美经验中常常能够发现审美可以引起悲伤,而且不需要转化为愉悦,悲伤本身就有独立的审美价值。这种在审美中所激发的悲伤,首先是非功利性的,不是具体的肉身痛苦,不源自对象以其实存对我们生命的伤害;其次这种悲伤是纯粹的,是凭借我们内心的感受而直接发生的,无目的性,非概念性,无关乎价值判断;这种悲伤也具有一种绝对性,它是无缘由的,无条件的,却又是普遍的,甚至具有一种形而上学性。这种无功利的、纯粹的、绝对的悲伤,可以称之为“自由悲伤”,从而与康德推导出的“自由愉悦”相对。审美有两种样态,一种追寻自由愉悦,一种追寻自由悲伤,前一种审美让我们追求精神的解放,体验自由,而后一种审美让我们追求个体心灵的确证与醒悟,回归自我。自由的自我,或许是两种审美的共同归宿。
