The white low-density powder of the the sodium salt of polyaspartic acid was got by dropping the hydrolyzable solution to wiscked high speedly carbinol which Consumption amount is about 3-6 times to the amount of solution, the powders density is about 0.35g/ml.4 Polyaspartic acid was characterized by NMR and IR.5 The scale inhibition behavior of polyaspartic acid was studied and result shows: The calcium carbonate inhibition rate is up to 99% at the dosages of 12.5mg/ Land when pH value is 9.0, Ca2+ concentration is 120mg/L and HCO3- concentration is 366mg/L.6 The primary design was put forward for industrialized production of PASP.

Dye can bring a little color to life, most clothing is color with dyes, modern manufacture dyes can be costly, natural dyes from plan t and animal products have been used since ancient times, so this week, we describe by natural way to dye world, the advice comes from information written by Jenny Tim of the intermedial technology development group in Briton, this anti group is now called practical action, there are several messages to put dye onto material, the vent message for example, can be used to dye wool with onion skins, for this example, use 100 grams of natural wool, the wool must be clean, leave it overnight in water and liquid soap, then wash it with clean water that is a little warm, gently out the water, a solution called a moderant is used in the dying process, a moderant helps fix the dye to the material, traditionally moderants were found in nature, wood ash is one of example, but chemical moderants such as ironare popular today, iron is so would in many stores, it is often mixed with queen of daughter, a finding powder commonly used in cooking.
使用染料可以为生活带来更多的色彩。许多的布料都是通过染料来上色的。现代工业制造的染料通常都非常的贵,从古时起,人们就知道从植物或者动物产品中提取天然染料。这周,我们就来讨论一下如何用天然的方法来给羊毛着色。这一建议来自英国中级技术发展组的Jenny Dean的信息。这一古老贫穷的小组现在被称为实用性活动。把染料加到材料上有几种方法。其中之一是大桶法。举例来说,就是用洋葱皮来染羊毛。这一例子中,用100g的天然羊毛。羊毛必须清洗。用液体肥皂浸泡过夜。然后用温的干净的水冲洗它。轻柔地把多余的水分压挤出来。一种叫做媒染的溶剂也用于染洗过程。媒染是用来固定染料和材料的。传统的方法是,媒染是来天然的,比如木灰。但是像明矾这样的化学媒染在今天也是很流行的。明矾在许多商场都有出售。它通常和一种经常被用于烹调的粉状物-酒石混在一起。我们用多一点点的辛苦,来交换多一点点的幸福

In this paper, the 3-D finite element relocating mesh method is used to calculate the temperature field and the thermal creep stress field of spillway dam and mid level outlet dam in certain roller compacted concrete gravity dam, sensitivity analysis have been down with different parameters, such as placing temperature, the location of cooling pipe, cooling temperature, time for water supply, ascended-layer of concrete, intermissive time and different placing time, and the commendatory construction scheme have been put forward in such analysis; according by the test result on the two scheme of concrete aggregate combination (basalt as coarse aggregate and limestone as fine aggregate, basalt as coarse aggregate and basalt as fine aggregate), simulation analysis on temperature field and thermal creep stress field of the commendatory construction scheme have been down, and analysis have also been down on temperature field and thermal stress field of the two different aggregate combination, the result indicates that the spillway dam and mid level outlet dam which adopted these two aggregate combination can both satisfy the require of design crack resistance in concrete, furthermore limestone as fine is better than basalt as fine aggregate; the effect of summer water storage and winter water storage on the temperature field and thermal stress field have been analyzed, comparing with winter water storage, in summer water storage scheme the maximum tensile stress at abnormal concrete in upstream fill is decreased by 0.1~0.3MPa and there are no evidence change of the maximum tensile stress at other parts, which indicate that summer water storage is avail for the crack resistance of upstream fill; according to the simulation calculating result and comparing temperature simulation calculating results and temperature controlling measures of some similarity projects both completed and construction, synthesis appraise have been carried to the design temperature controlling measures of dam, and the temperature controlling measures of this project have been brought forward, all these have great reference value on the design of temperature controlling measures and the optimization of the construction scheme.
本文采用三维有限元浮动网格法仿真计算程序,对某碾压混凝土重力坝的溢流坝段和中孔坝段分别进行了三维有限元温度场和温度徐变应力仿真计算分析,对浇筑温度、冷却水管的布置方式、冷却水温、通水时间、浇筑升程和间歇时间、不同开始浇筑日期等参数进行了敏感性分析,在此基础上提出了推荐的施工方案;根据两种骨料方案(玄武岩粗骨料+灰岩细骨料方案;玄武岩粗骨料+玄武岩细骨料方案)的混凝土性能试验研究成果,对推荐的施工方案进行了温度场和温度徐变应力仿真计算,并对比分析了两种不同骨料情况下的温度场和温度应力,结果表明溢流坝段及中孔坝段采用上述两种骨料均能满足混凝土的抗裂设计要求,且灰岩细骨料优于玄武岩细骨料;计算分析了夏季蓄水和冬季蓄水对坝体温度场和温度应力的影响,夏季蓄水方案与冬季蓄水方案相比,坝体上游变态混凝土区域最大拉应力小0.1~0.3MPa,其他部位最大拉应力无明显变化,夏季蓄水对坝体上游面混凝土的抗裂有利;根据仿真计算成果并通过比较国内一些已建和在建的类似工程的温度仿真计算成果及采取的温控措施,对大坝的设计温控措施进行了综合评价,并提出了该工程的温控措施,对温控设计和优化施工方案具有重要参考价值。

We chose 30 type milli-needle as tools after routine sterilization. Usually we pick levelly 0.5-0.8 inch at Baihui, 1. 5 inch at Jiaji, 1-1. 5 inch inclinedly to the nose tip at Fengchi, 1-1. 5 inch inclined at Jianjin, 1-1. 5 inch at Shousanli. After obtaining gas by rotating method, we used moxibustion at Baihui by lighting the moxa strip, and put the acupuncture and moxibustion therapeutic instrument (made in shanghai, G6805-Ⅰ) at other acupuncture points. We chose thin and dense wave and adjust the current strength according to endurance of the patients, and 20 minutes each time, one time every other day, 15 times a course.

The economist Menzie Chinn, using purchasing power parity exchange rates, reckoned the renminbi's undervaluation to be 40%. But, after the World Bank revised China's GDP in PPP terms downward by 40%, that undervaluation disappeared. Nick Lardy and Morris Goldstein suggest that the renminbi was probably undervalued only by 12-16% at the end of 2008. And Yang Yao of Beijing University has put the misalignment at less than 10%.
经济学家陈庚辛基于购买力平价的计算显示,人民币汇率被低估40%,但如果考虑世行用购买力平价对中国GDP的调整,高估的40%几乎全部抹平;拉迪和戈德斯坦的结论是人民币被低估12%~16%(截至2008年底);北京大学姚洋的计算显示只有不到10%。
