The partial least-squares regression model is built up to forecast crop leaf water potential of estival maize.Thirdly, atmosphere aspect, the low water age has been forecasting by R/S method of fractal theory in Si Chuan middle region. The chaotic behavior of agriculture meteorologic factors (average temperature, max temperature, min temperature, temperature of the earths surface, evaporators, precipitation, relative humidity, sunlight time) time series is investigated using the phase-space reconstruction technique, and the delay time and relation dimension and min embedding dimension and Lyapunov exponent and Kolmogrov entropy is calculated. The atmosphere water potential is calculated by surveyed data, and the day change law of atmosphere water potential and the relation between it and sun radiation has been discussed.

结果表明，各形态氮月均浓度之间差别较大，具有明显的季节性，原因主要与人类活动、降水强度及频次、风向、地理位置以及氮氧化物自然排放有关；湿沉降的TN组成以TIN为主（51.38％-98.96％），TIN又以NH^＋ 4-N和NO^- 3-N特别是NH^＋ 4-N为主，降水天气系统的路径在很大程度上影响着降水中各形态氮的组成；降水量与各形态氮浓度均呈较弱的负相关（P〉0.05），而NH^＋ 4-N与NO^- 3-N、TON均呈显著正相关（P〈0.05），它们可能具有同源性。

In this work, according to the fact that the precipitation of ferreous and ferric iron to form magnetite nanoparticles is the fast reaction, we designed a new forced mixing route to prepare magnetite using nitrogen press in T type of tube to reach the intention of mixing in microscale and avoiding oxidation.

The results showed that three reasons caused the failure of the fibre materials:1the fibre materials transforming into powder which was caused by the precipitation of mullite at high temperatures;2cracking and spalling of the refractory coating and refractory fibre felt;3low strength of the refractory fibre flet.

结果表明：硅酸铝质耐火纤维在高温下析出莫来石晶体导致纤维材料的粉化，耐火涂层和耐火纤维毡的开裂、剥离脱落，耐火纤维毡强度很低是导致纤维材料失效的3个主要机理。研究结果为新型耐火材料的研制或改进提供了重要依据。

Although the quality of day lily of Qingyang city is best in the whole country, the day lily is planted fragmentarily at the residence, roadside, bank of the canal, low bank of border, and district of field, and also do not form the best product region and suitable planting technology. The product region environment condition of day lily in Qingyang city was analyzed from2001 to 2005, the advantageous product regions of day lily in Qingyang city was planned, and planting technology of day lily was studied. The main result of study were as follows:First. Qingyang city belongs to dry agricultural region, its solar radiation is quite rich, but the water resources is short in all district, the agricultural production depends on the natural precipitation.

生产的黄花菜质量在全国名列前茅，但是庆阳的黄花菜多在宅旁、路边、渠岸、田边地埂等零星地进行生产，没能形成优势产区，对栽培技术研究也较少。2001年～2005年我们分析评价了庆阳市黄花菜产区环境，进行了黄花菜优势产区区划和旱作栽培技术研究，主要研究结果如下： 1 庆阳市太阳辐射比较丰富，水资源缺乏，农业生产靠天然降水，属旱作农业区，河流大部分水质较好，灌溉水源基本未受到污染。

When Gluma is applied in vivo, two reactions occur: first, GA reacts with part of the serum albumin in dentinal fluid, which induces a precipitation of serum albumin; and, second, the reaction of GA with serum albumin forms dihydropyridinium, whose disproportionation gives rise to free radicals, and the free radicals induce the polymerization of HEMA.

首次提出Gluma的脱敏机理为：当Gluma涂在过敏的牙本质上时，首先戊二醛交联牙本质液中的血清蛋白并产生沉淀；同时戊二醛与血清蛋白的反应产生二氢吡啶盐，它发生歧化反应，歧化过程中会有自由基产生，从而引发HEMA 聚合，生成另外一部分沉淀，这两部分沉淀共同堵住牙本质小管，起到了脱敏作用。
