Analyses of two nominative proxy signature schemes proposed by Seo et al.(2003) and Huang et al.(2004) are given in this paper. The results show that neither the scheme has the property of strong unforgeability.

摘要该文分析了Seo等(2003)和黄振杰等学者(2004)提出的两个提名代理签名方案，指出这两个方案都不具备强不可伪造性。

It is not clear, however, to what extent these mechanisms might overlap because there is some evidence that the local stimulus of more frequent milking can, in turn, cause more nutrients to be delivered to the udder at the expense of other tissues (DePeters et al., 1985; Kazmer et al., 1986), although there is no evidence of major repartitioning comparable to that seen with growth hormone injections.

Bauman 和弗农，1993它不清楚，然而，到什么范围因为有比较时常发生挤奶的当地刺激能，依次的一些证据，所以这些机制可能重叠，引起要递送到乳房的较多的营养物牺牲其他的薄纱织品(DePeters 及其研究同仁，1985； Kazmer 及其研究同仁，1986)，虽然没有对于主修科目的证据再分配可比较的对那与生长荷尔蒙注入一起见到。

在冠状窦起搏周长为300 ms和静脉给予1 mg/kg氟卡胺后，在房扑组病例中SD2均由上至下进行性延迟，指示第二个心房波激动主要是由间隔激动沿三尖瓣环逆钟向兴奋右房游离壁所致，显示出跨界嵴传导功能性阻滞。

These skills are originally chosen to parallel the aptitudes defined by the GATB and the occupational titles set by Chang et al.(2000) and Wu et al.(2001).There were four sets of work samples developed in the first year including: janitor, baking assistant, supermarket aid, and assembling worker work samples.

接著，选取其中最常从事之职务编制工作样本，已初步选取清洁员之擦拭能力，烘焙助手之面团裁切与饼乾制作，超商助手之货品检视、货品上架与搬运、出货点数，与组装作业员在分类、装袋及塑胶装罐生产线所涉及之各项能力完成系列工作样本编制。

Presence of water in the reedbed is important to provide the fish prey that bittern rely on in Britain (Gilbert et al.,2003; Gilbert et al., 2005), however British female bitterns are not restricted to feeding near the nest and will regularly fly up to 2 km to find food for their young.

水出现在reedbed是重要提供鱼牺牲者苦汁在英国(等Gilbert依靠， 2003年； Gilbert等， 2005)，然而英国雌性麻鸭子不限于哺养在巢附近，并且通常飞行2 km发现他们的年轻人的食物。

These units do not store large amount of energy but the power capacity should be considerable. A medium SMES example is the one installed in Tacoma, Rogers et.al.(1) and Boing et.al.

其所储存能量并不大，但应有相当的功率容量，安装于Tacoma (见参考文献1)和Boeing （见参考文献2）的SMES就是中型SMES的例子。

Objective: Pino et al reported that strip lesions were produced when the distance between two probe was 2 to 6mm, and it resulted in unipolar lesions when they were spaced more than 6 mm apart. However, in clinical studies and some other reports, bipolar radiofrequency treatment was also effective when the distance was 10mm. Therefore, we duplicated Pino et al's experimente to study the lesion morphology when the distance of two radiofrequency cannulae was arranged between 2 and 10mm.

目的： Pino等人的研究发现双针间距在2-6mm之间时双电极之间可形成带状毁损，而8mm、10mm间距时双电极针成为独立的电极毁损，而在临床研究及某些文献报道中可以看到双电极间距在10mm时治疗同样有效，因此本文重复Pino等人的实验，研究双针电极间距在2-10mm时双针射频毁损形态。

The pressures produced by these species are generated throughout the stem, but can co-occur with some degree of root pressure Ewers et al. 2001, Sperry et al.

压力产生的，这些物种所产生的整个干的，但可以一起合作，出现某种程度的根压（ ewers等， 2001 年， sperry等人1988 年年）。

The effects of various structure parameters of gemini surfactants such as nature of the hydrophilic head groups,nature and chain length of the hydrophobic tail groups,nature and chain length of the spacer groups,and nature of the counter ion et al.on their dissolution properties,surface activity,micelle morphology,foaming performance and lime soap dispersing power et al.were summarized.

综述了双子表面活性剂亲水头基的性质、疏水尾基的性质及长度、连接基的性质及长度、反离子等结构参数对其溶解性、表面活性、胶束形状、起泡性及钙皂分散能力等的影响。双子表面活性剂是一类新型表面活性剂，具有临界胶束浓度低、表面活性高、增黏能力强等一系列优异性能，这些优良性能使其具有良好的应用潜力。

In other words, from historical perspective, socialism has experienced a history of over 100 years from utopian socialism put forward by Saint Simon et al and Marx's scientific socialism to the socialist countries founded byLenin, Mao Zedong et al, and to the disorganziation of Eastern European socialism and China's socialist reform, but it is not a simple review of the history, it is, however, an _expression of the survival experience and visual experience of the artists living in socialist China.

换句话说，尽管从历史的角度看，从圣西门等人的空想社会主义，马克思的科学社会主义，到列宁、毛泽东等人把社会主义的观念变为现实的社会主义国家，再到东欧社会主义的解体和中国社会主义的改革，社会主义已经走了一百多年的历史过程，但是本展并不是这一历史的简单回顾，而是要表达生活在社会主义中国的艺术家们的生存体验和视觉经验。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
