TRIZ的40个发明原理在化工行业中的体现 总被引:2,自引:2,他引:0
TRIZ理论是Altshuller在分析了大量专利的基础上提出的,40个创新发明原理是其中的重要内容之一,包括分割、抽取、局部质量特性等原理。理论认为尽管很多专利虽然来自不同国家、不同领域,而且解决的也是不同的问题,实现的是对不同系统的改进,但是,这些专利是利用了某些相同的方法。也就是说,很多的原理和方法在发明的过程中是重复使用的。笔者根据发明原理的内容并结合工作实际,归纳总结了TRIZ的40个发明原理在化工行业中的实际体现。 相似文献

“发明问题解决理论”(TRIZ)的起源出自于前苏联对工程和实用专利的分析。因此,“发明问题解决理论”(TRIZ)的40条发明原理的创建可用于解决工程问题。之后,人们做了大量的工作,试图将这些发明原理的应用范围扩大到非工程领域.例如:商业、个人或健康方面的“软”问题。 相似文献

我们熟知的液体比重测定法已有好几种,但欲得到准确与精密的结果倒是一个大难题。最近美国化学会所发表的测定液体比重新法解决了这个困难,它的操作既简捷,结果又准确。这个发明在化学工业的发展史里将占一重要地位,因为它的精细结果能准确到小数点後第四位,除掉这几个优点外,仪器的装置非常简单,操作的人不需经过特殊的训练。仪器的装置是一个直径相等的细长弯玻璃管,管的两端垂直平行,下端安插入烧杯A与B内,两管间置一米突尺,管的顶部中点则与一真空抽气机(Vacuum pump)相衔接。烧杯A内盛已知比重之液体(Sp.gr.A.),烧杯B内置欲测比重之液体(Sp.gr.B.)。装置就绪後,将玻璃管内之空气,用抽气机徐徐抽出,烧杯内之液体则因管内之空气排出而上升,共上升之速度与液体之重量成反。比待升至 相似文献

Mixing in a partially filled beaker or conical flask using oscillator shaker tables is routinely used for cultivation of biological cells. The present study seeks to gain a better understanding of fluid flow inside a beaker on a shaker table and the fluid motion influence on the mixing of cells within the fluid medium used for their cultivation. The imposed oscillatory motion on the beaker induces free surface deformations, which may cause laminar and low shear flow environments thus uniformly mixing the fluid medium. The low shear and uniformly mixed cell culture medium are requirements necessary for optimum cellular growth. In this study, fluid flow due to periodic and horizontal circulatory oscillations at a beaker boundary has been analyzed both numerically and experimentally. A partially filled beaker was modeled as a circular cylinder, and the cell culture medium was modeled as an incompressible fluid with a free and deformable liquid interface. The three-dimensional numerical model that can resolve the free surface deformation was based on finite difference scheme based on the “Marker-and-Cell” method. The method was used to determine the free surface deformation, its coupling to the flow dynamics within the beaker, and the resulting stirring effects. To verify the numerical model and validate the results, a simple flow visualization experiment was performed using an ion laser sheet to optically section flow chamber and reveal the flow pattern. The flow patterns obtained using numerical simulations were similar to those obtained experimentally through flow visualization. This study provides useful information that can be used to optimize the operation of a shaker table necessary to mix uniformly the cell culture, ensuring cell growth. In addition, this model can be extended to study the mixing processes in any chemical reactions within a partially filled container subjected to oscillatory forces. 相似文献

The acidity of low and high free fatty acid containing feedstock varieties and biodiesel production intermediary products
were tested using a variety of standard methods by the use of manual and automatic titration apparatus. The objective was
to select the optimal test method for intermediary products in biodiesel processing and to optimize the selected technique
by reducing the extent of bias. We found that there are two major reasons for variations in electrode potential readings.
Colloid chemistry has an impact on the initial phase of titration by breakage and reformulation of the partially disperse
system. Electric and magnetic fields in the titration beaker were the main reasons for sensitive fluctuations in electrode
potentials in the potential range of interest for acid number readings. Refluxing the analyte with the diluting solvent proved
to be an efficient technique to offset the influence of colloid processes. Addition of a filter electrolyte to the titration
solvent allowed the filter fluctuations to be related to changes in uniformity of electric and magnetic fields in the titration
beaker. Addition of filter electrolyte improved signal reliability than shading the external noises by wrapping the titration
beaker in aluminium foil. Mathematical interpretation of potential readings revealed the extent of improvement in electrode
potential fluctuation by the techniques employed. Both the aqueous and non-aqueous titration are suitable for accurate testing
the acid number of biodiesel feedstock and intermediary products. 相似文献
