浅析包装中色彩运用的文化原则

从某种程度上讲,包装是对产品的一种定位和阐释。心理学有关研究表明,人的视觉器官,在观察物体时,最初的20秒内色彩感觉占80%,而形体感觉占20%:两分钟后色彩占60%,形体占40%;5分钟后各占一半,并且这种状态将继续保持。可见,包装给人的印象多么迅速、深刻、持久。国外学者曾有过一项研究,发现由广告媒体招徕的顾客中,有33%的人在销售现场会选择包装吸引人的品牌,包装重要性不言而喻。可以说,包装的素材、形式和色彩等因素综合在一起,将产品引伸至一个深层的文化氛围。     

Integrated Personal Mobility Architecture: A Complete Personal Mobility Solution

The high expectations and demand for users to access the Internet from anywhere at anytime has made user mobility an important part of the design and development of the next generation mobile communications and computing. Traditionally user mobility has been divided into two areas: Terminal Mobility and Personal Mobility. In recent years terminal mobility has focused on the movement of the terminal and developed extensions to IP protocols such as Mobile IP. In contrast, personal mobility has only received limited attention, and is somewhat lagging behind. This research has either focussed on personal mobility in communications or personalisation of operating environments. As a result, to date no framework for providing true personal mobility has emerged. In this paper, we introduce a new personal mobility framework called IPMoA (Integrated Personal Mobility Architecture), which integrates both aspects of personal mobility to provide a complete personal mobility solution, and illustrate the viability of this approach through a proof-of-concept implementation.     

浅谈水闸安全检测

通过对华东沿海地区80年代以前修建的一些在役水闸工程的系统安全检测和分析,发现了水闸工程存在的安全隐患,同时也了解水闸工程尚有的潜在能力。提醒水闸管理部门,在役水闸满足目前社会发展需要的同时,还必须高度重视水闸的安全生产运行和管理。水闸安全检测就是利用先进的检测手段,为业主及时、高效、经济和高质量地解决水闸工程存在的实际问题。     

甲基丙烯酸三氟乙酰氧乙酯的聚合

对甲基丙烯酸三氟乙酰氧乙酯(TFAOEMA)的阴离子聚合及原予转移自由基聚合进行了研究。常用的阴离于引发剂如丁基锂、1，1-二苯基已基锂等很难引发TFAOEMA的阴离子聚合，而碱性较弱的引发剂如三乙基铝却容易引发，且产率较高。以氯化亚铜、五甲基二乙基三胺、溴代丙酸乙酯为引发体系的TFAOEMA的本体原子转移自由基聚合符合活性聚合特征。但在四氢呋喃为溶剂的原子转移自由基聚合中却存在活性中心失活现象。以末端含卤素的聚甲基丙烯酸甲酯为大分子引发剂，引发TFAOEMA的原子转移自由基聚合，得到了含氟双嵌段聚合物。     

水溶液辐射分解产物对金属材料腐蚀的影响

实验研究了水辐射分解作用对高放废物深地质处置容器材料的影响。在高放废物深地质处置库附近的地下水,受辐射线作用后分解出氧、氢和氧化产物(例如H_2O_2等),于是在高放废物容器周围形成一个氧化场,导致高放废物中的某些重要放射性核素(例如U,Np和Tc)易溶于水,并向远域迁移。本实验中的含FeSO_4(0.13 mol/L)水溶液在吸收剂量为0、20、60、180、500kGy的射线作用下,其氧化还原电位(Eh)值由+357mV增至+414 mV;在不同吸收剂量的射线作用下,金属Cu、金属Al、0.357 mv金属Fe和不锈钢(后者是我国拟采用的高放废物包装容器材料),在水溶液中的氧化侵蚀强度,分别比在无辐射情况下的大0.2-6.1倍。     

Many-body effects and electron tunneling in metal-insulator-p-type semiconductor structures

Investigation of the tunneling conductivity σ _d(V) of structures made on a highly doped, narrow-gap p-type semiconductor HgCdTe reveals an abrupt increase in this quantity at voltages corresponding to the start of tunneling into the conduction band. It is shown that the observed functions σ _d(V) cannot be described in the framework of a model based on single-particle tunneling. It is proposed that the abrupt increase in σ _d(V) is attributable to tunneling into exciton states. Fiz. Tekh. Poluprovodn. 32, 1069–1072 (September 1998)

A study on the anodic protection of Titanium evaporators in Al2(SO4)3 solution

The feasibility of the anodic protection of titanium evaporators in Al₂(SO₄)₃ solution was studied by the measurement of polarization curves, weight loss, solubility of passive film and AC impedance. The protection parameters and efficiency were determined. In addition, the practical technology of anodic protection was studied by screening reference electrodes and auxiliary cathodes. Throwing power was also measured. Four rows of tube-type evaporators of titanium have been anodically protected in situ. Field tests lasting more than one year show satisfactory results.
