At first, the last low-frequency image after wavelet decomposition can be an initial approximation of the next low-frequency image. It is tested and verified that the last low-frequency image can diffuse and converge to the next low-frequency image. On the other hand, the next low-frequency image can also diffuse and converge to the last low-frequency image. Above process just presents the gradual variation of wavelet decomposition and reconstruction.
首先,用小波分解后下层的低频图像作为对上层低频图像的一个初始近似,验证了由上层低频图像经方向扩散方程可逐渐扩散收敛到下层的低频图像;反过来,由下层低频图像经方向扩散方程亦可逐渐扩散恢复到上层低频图像,这正体现了小波分解与重构的渐变过程。

The study wanted to make clear the index of freeze injury to Lichi. Low temperature data of Fujian province recent years and now, information about freeze injury of lichi in survey and literature were gathered, refering to photo and corresponding low temperature data about five county in winter in 1999 that provided by guangxi research institute of meteorological disaster mitigation; by statistic methods dealing with above information gave the result on the extreme low temperature data gathering by thermometer screen and the freeze injury grade of lichi; correlation analysis on data of freeze injury and the extreme low temperature indicated that the temperature of no freeze injury and slight freeze injury and moderate freeze injury and serious freeze injury and most serious freeze injury is respectively -0.3℃ and -1.9℃ and -3.1℃ and -3.8℃ and -4.1℃; Difference of teperature between every freeze injury grade of lichi turned to disappear when grade increased.
为了弄清给荔枝树造成损害程度低温指标,收集了福建省近几年冬季考察的低温资料、荔枝树低温冻害调查资料和有关参考文献中记载的荔枝树冻害资料、同期的低温资料,参考广西壮族自治区气象减灾研究所1999—2000冬季5个县荔枝树冻害的照片资料和相对应的低温资料;经统计处理整理成同时同地荔枝树的冻害级别与百叶箱中的最低气温资料;据荔枝树的冻害资料和最低气温资料进行相关统计分析,经相关分析表明:它们可以用一元二次方程进行拟合;荔枝树的无冻害、轻冻害、中冻害、重冻害、严重冻害的最低气温分别为-0.3℃、-1.9℃、-3.1℃、-3.8℃、-4.1℃;荔枝树各个冻害级别之间温差随着冻害级别的提高而缩小。

In chapter two, three and four, we have a stationary description ofpolysyllable words in One Hundred Buddhist Parables as objectively as possible. Forexample, its number, frequency, components, structure, new words with their newmeanings and so on. As for the later two aspects, we have complete counts by meansof statistics. Through the conditions of polysyllable words, we can have a generalidea of the development of vocabulary in the South and North dynasties. We combinefixed quantity study with fixed quality study.
在第二、三、四章中,我们对《百喻经》中的复音词尽可能客观地作了一个静态描写,如它的数量、频率、组成、结构和新词新义等方面,其中后两者都是用数据统计方式,穷尽式地对《百喻经》中复音词的各种结构和新词新义的数量进行统计,这样可以使我们通过本书的复音词概貌来基本了解整个南北朝时代词汇发展的大致情况,把定量研究和定性研究结合起来。

他以今年初的雪灾为例,现在公路的信息归交通部门管,交通事故归公安部门管,天气情况由气象部门把握,运输煤炭要经工业部门调控,运输蔬菜要经农业部门调控。灾难期间向北京运蔬菜一事,就要劳动几个部门召开会议,电视讲话,指令保障运输路线的畅通。假如用SOA架构,完全能够只用一个统一的应急指挥中心,但是这方面的工作仍然没有足够的推动力。

Through lots of tests, the new technology of preparing the polymeric ferric aluminum silicate sulfate by using the waste-acid of Ti02-industriy and the coal fly ash has been designed. The highest Al-acid stripping rate can be achieved by the waste sulfate acid under boiling degree for 1. 5h when the mass ratio between NaCl and Coal Fly ash is 0. 05:1, as well as that between Coal Fly ash and Waste Acid ratio is 1:10. By means of the oxidation-polymerized reaction under 40-50*C and normal pressure, using NaNCkas catalyst and air as oxidation, the polymeric ferric aluminum sulfate can be obtained. The poly-silicic acid is polymerized with soluble glass in the optimum conditions of pH=5-6 and the concentration of Si02 is about 3%. The inorganic high molecule coagulant of PFASS is synthesized with the poly-silicic acid into the solution of polymeric ferric aluminum sulfate.
