On the poet's choice, mainly be decided by two standards, one is the popularity and influences of works; two is the meaning of the creations development that it create for the whole colony. Owing to above two standards, the writer chooses seven writers to launch the treatise, they are Jidi Maja, Jimu Langge, Luwu Laqi, Ma Deqing, Aku Wuwu , Asu Yuer, Eni-Mushashijia. In discussing the process, the writer used the nationality and Poetics of the poem as the latent clues, emphasized to inquiry into three main roads and three main realms. On the article structure, the full text mainly is divided into two parts, one is the concrete imago analysis to each poet creations, two is upon the analytical foundation the integration of the theories, with this the treatise could be united into an organic whole. In regard to the conclusion, we educe the characteristics of the colony is deep consciousness to the nation culture, also extensive exploration and attention to poetics. The blemish is the inside emotion and sensibility is similar or duplicate and that the creation pattern is narrow. The main develop threads of the colony are upon the female clan culture the diverse poem skill investigation, its nation culture value tropism present the rising spiral type of return- leave- return again.
在研究方法上,本文以意象分析法为贯穿全文的主要方法,通过对意象的具体分析来透视凉山诗群的诗歌世界;在诗人的选择上以其作品的影响力及意义为标准,选择了这一诗群的七位诗人展开论述,他们分别是吉狄马加、吉木狼格、倮伍拉且、马德清、阿库乌雾、阿苏越尔、俄尼·牧莎斯加;在论述过程上,笔者以诗歌的民族性和诗性作为前后贯穿的潜在线索,着重探讨了这一诗群创作的三个主要倾向和三个主要领域,前者详论,后者略述,具体表现在对前三位诗人的论述以诗人论的形式详细展开,探讨他们所代表的凉山诗群发展过程中的三个主要创作倾向,即民族文化的深层开掘、诗艺的实验性探索和艺术哲学的尝试性建构,对后四位诗人的论述则以主题的方式展开,探讨他们所代表的凉山诗群在爱情诗、乡土诗和文化诗三个领域的探索;在文章结构上,全文主要分为两大板块,一是对各位诗人创作的具体意象分析,二是在前文分析的基础上进行理论的整合,以此将前面散珠似的论述贯穿成一个有机整体;在结论上,我们通过整合得出:1、凉山诗人群新时期以来诗歌创作的大致发展脉络:在母族文化的基质之上的多元诗艺探索,其民族文化价值取向呈现为回归—离去—再回归的螺旋式上升形态;2、新时期彝族凉山诗人群汉语诗歌创作的特点,即民族文化意识的深层自觉,对诗性的关注和探索;3、新时期彝族凉山诗人群汉语诗歌创作的缺陷,即情感意蕴的雷同和创作格局的狭小。

At the same time, combining with the actual condition of delivery pipeline of our country and some prevalent leak detection and location methods, this paper raised a method, which is based on wavelet analysis and negative- pressure-wave to detect and locate the leakage. Jobs in the paper are as follows:As affected by gas density, pressure, specific heat and pipe material, the velocity of negative-pressure-wave improved depending on the energy conservation. At one time, taking the affection of velocity of gas flow, the location formula was modified in some degree.When locating the leaks with location formula, the iterative approach algorithm was adopted as a new method to increase the location accuracy level of system.Multi-scale decomposition and reconstruction of wavelet transform is utilized to filter the noise of negative-pressure-wave, which was brought by leakage. With the capacity to detect the signal singularity fast and accurately, wavelet transform was used to catch the break point of pressure signal. The work improved the accuracy of At in location formula, accordingly improved the location accuracy.Wavelet is a suitable tool for signal analysis. The distinct character is that the mother-wavelet is of optional. That means choosing different mother-wavelet will get different analysis result. So we studied how to choose mother-wavelet and its scale for signal singularity detection. The method is to choose a wavelet by regularities of the wavelet and the signal.Finally, a plan, which bases on SCADA system for inspection and detection of natural gas leakage, is proposed in the article.
其中,主要进行了以下几方面的工作:针对泄漏产生的负压波在管道中的传播速度受媒介的密度、压力、比热及材质等因素的影响,而非声波在空气中传播的速度,本文利用能量守恒原理,对其进行了修正;考虑到管内气体流速对压力波速的影响,对原始的负压波定位公式进行了一定程度的改进,并在利用定位公式进行泄漏点定位时采用逐步迭代逼近算法,提高了系统的定位精度;利用小波变换的多分辨率分解和重构技术,对采集到的管道发生泄漏时产生的负压波信号进行了降噪处理;并利用小波变换技术对信号奇异点的快速、准确的识别能力,对经上述消噪后的负压波信号进行了奇异点捕捉,精确捕捉的结果提高了定位公式中上下游站点采集到的负压波奇异点的时间差△t的精度,从而进一步提高了定位的精度;考虑到小波变换是一种基波可变的信号分析工具,也就是说,不同的小波基波对信号分析的结果将有很大差别,这势必影响最终的处理结果,因此,我们又对比分析了本课题中小波基及尺度的选择问题,依据规则性系数相似性原理对母小波的选择进行了探索性研究;最后,还提出了基于SCADA的泄漏检测与定位系统的软件开发构想及系统的嵌入方案。

Painting which is the mainstream of the western art is extremely representational in the aspect of the space concept. But relieves combine the paintings'complanation with sculptures'extensity .so we decide to research the process of the evolvement and the interaction between paintings and sculptures. We expect to discuss the space and art expression in the western art and relieve ,so I can have a further comprehension about the space of optical art. The comprehension can not only help us understand the traditional western paintings and relieves better, but also make us comprehend the space concept of modern art better, to set the artistic creations of contemporary paintings and relieves into action.
油画,作为西方绘画的主流形式,在空间形态的表现上极富代表性,而浮雕兼具绘画的平面性与雕塑的实体空间性,因此,我选择研究油画与浮雕在空间上的演变过程及其相互影响,以期可以从一个侧面来探讨西方绘画与浮雕中的空间观和艺术形态表现,从而对视觉艺术的"空间"有更深一个层次的了解,这不仅有利于我们理解传统的西方油画和浮雕,也能使我们更好地理解现代艺术的空间观念,进而更好的推动当代的油画和浮雕创作。

objective to investigate the existence of the erythropoiesis inhibitors.methods the present study included twelve undialyzed esrd patients with anemia.the sera from the uremic patients were added to cfu-e and bfu-e culture in the concentrations ranging from 1.25% to 5%.in vitro cfu-e and bfu-e growth in the presence of sera from esrd patients was compared with in the presence normal human subjects with the use of normal mice bone marrows.results the effects of the sera from uremic patients on cfu-e and bfu-e colony growth in concentrations ranging from 1.25% to 5% were investigated to be dose-dependent.the effect increased with the concentrations increasing of the sera(p<0.05).there were not significant inhibitory effect on the cfu-e and bfu-e growth of mice bone marrow in vitro from sera of the normal subjects.conclusion the erythropoiesis inhibitors exist in uremic sera which has a dose-dependent inhibitive effects on the growth cfu-e and bfu-e of normal mice bone marrow cells.

The major findings are:⑴During the intelligence test for the three groups of students, for half of the students or most of the students their scores on the all-including scale, the language scale and the performance scale all increased to various degrees;⑵From the analysis of the relationship between intelligence and reaction time, it is found that the result of this study confirms the existing views that there is a negative correlation between intelligence and reaction time, and the negative correlation is more evident when it is choice reaction time;⑶Different motor skills have different influences upon children with lower intelligence. Though the difference is not large, the average increasing percentages in the sample T tests for the three groups before and after the experiment show that the effect of open motor skill is the best, that of the synthetic motor skill or the open-closed is the better, and that there isn't a marked change in the closed motor skill trainees;⑷While analyzing the result of the experiment, it is found that the scores on the performance scale are higher than the scores on the language scale, especially in the open motor skill group, which tells us that the intelligence improving effect of physical training is realized to a greater extent through increasing their performance abililty.
