The ammonia volatilizing of fertilizer is suit to the dynamic equation as Y=a+bt, the coefficients in the equation are related to the kind of fertilizer, temperature and water content of soil, and the dynamic equation about ammonia volatilization including water and temperature and the is developed. In addition, the dynamic equation about ammonia fertilizer affected by interaction of water and temperature is gotten.

A conveyor belt should not pass through a partition between a grade A or B area and a processing area of lower air cleanliness, unless the belt itself is continually sterilised e.g.

传送带不可以穿过A/B级区和其他低洁净度处理区域的间隔，除非传送带被持续的灭菌。

A series of perovskite oxides are synthesized by means of blend deposition using the nitrate of A and B as the raw materials, and ammonia or sodium carbonateas sedimentation .A includes alkaline-earth metals such as Mg, Ca, Sr, Ba and rare-earth metalsLa; while B includes transition metal Cr, Mn, Fe, Co and Ni.

本文以A，B的硝酸盐为原料，以氨水或碳酸钠为沉淀剂，利用混合沉淀的方法合成了系列钙钛矿型氧化物。A选碱土金属元素Mg、Ca、Sr、Ba等及稀土金属元素La；B选过渡金属元素Cr、Mn、Fe、Co、Ni等。

On the other hand, as illustrated in Picture B and D, the price drop would become material objects' price drop because of the continuous flow syphonage capital. Pictures stood by Picture B and D can become anti-syphonage theory pictures. The syphonage pictures and anti-syphonage pictures can simply stand for two converse investment opportunities. Under normal situations, commodity's syphonage capital flow can demonstrate a slow increasing situation in the long run. But the situation is usually affected by supply-and-demand situation in the middle and short run. Especially in the type of gurantee sum exchange, the supply-and-demand situation is a major factor affecting commodity price even in a price dominated market. The commodity's ultimate price will comparatively alter when the outer influence changes, and sometimes the price may change to a completely converse direction as expected. In case of the above case, we need to observe and research the influential factors. However the research is not like the Butterfly Theory research on slight variables. Syphonage theory deems that if continuous observance extends more than a certain percentage, such as 10% influential factor, and we continue researching, immediately putting 10% influential factors into research scale, we could finish the all-round research on commodity price analysis.

其中，图A和C表示的图形我们成为正向虹吸图形，B和D代表的图形成为反向虹吸理论图形，这种正向虹吸图形和反向虹吸图形分别可以简单代表两种相反的投机机会，在正常情况下，商品的这种虹吸资金流从远期看会表现出缓慢的上升走势，但在中短期，走势经常受到供求关系影响，特别在保证金交易的品种中，即使是价格操纵的市场中，供求关系也是影响商品价格的主要因素，这种以供求关系为主导的市场中，虹吸终值并不是一成不变的，在外在影响因素发生变化时，商品终值也会相应变化，有时甚至会改变到和预期截然相反的方向，这就需要我们经常对相关影响因素进行跟踪和研究，这种研究并不象蝴蝶理论分析的微小变动因素，虹吸理论认为只要连续跟踪超过一定权重，比如10％影响权重的因素，并持续研究，及时将超过10％影响因素事件纳入调查范围，既可完成对商品价格分析的全面性探索。

The Circulation-hydrogenation Compressor Model BLC-305/A is an important equipment with Hydrogenation devices, which is imported by Lanzhou Petrochemical Company Refinery. Due to high-speed rolling periodically, the spare parts of this compressor, to a varying extent, show a lot of signs of wear and tear. Especially, the axle sleeve of the rotor axle of the compressor is so worn to the greatest degree that its work efficiency decreases by a big margin. Machinery Factory of Lanzhou Petroleum Processing and Chemical Complex has undertaken this task to repair the rotor.

BCL—305/A型循环加氢压缩机是兰州石化炼油厂从国外引进的一台用于加氢装置的重要设备，该设备经长周期的高速运转，零部件均有不同程度的磨损，特别是压缩机转子轴上的轴套磨损程度最大，使整机效率大幅度下降，兰炼机械厂承担了这项转子修复任务。
