不实用性

Therefore, photoelectric conversion efficiency of the current restrictions on the amount of solar energy use for electric cars, solar energy directly, as if the momentum will lead to a solar panel the size is too large, inconvenient to install, plus the cost of Too high, its usefulness would be greatly reduced.

由此可以看出，光电转换效率限制了目前对太阳能量的利用，对于电动车来说，若直接以太阳能作为动力，将导致太阳能电池板的面积过大，安装不方便，再加上成本过高，其实用性将大大降低。

第三部分是对于组合实物期权评估方法的案例分析。论文将组合实物期权评估方法应用于以ABC公司战略性投资为背景的案例中，验证了组合实物期权评估方法在不确定条件下投资决策中所具有的实用性。

The simulation results showed that the neural network model given in this paper is capable of forecasting the behavior of nucleation rate exactly and rapidly, and the maximum relative error does not exceed 5.9% as compared with measured values.

仿真结果表明，利用文中所提出的神经网络模型能够较准确、快速地预测结晶成核速率的变化，预测值与测量值的最大相对误差不超过5.9%，表明该网络预测模型有很大的实用性。

Flocculation+0.45μm filter is selected as the pretreatment of the method proposed here.(9) A set of standard methods for ASMs COD characterization is suggested in the thesis and it advantages are:①Respirometry is adopted to measure RBCOD and SBCOD;②SI is determined from raw wastewater and so there is no influence of inert products;③Heterotrophic biomass in wastewater is measured;④The key instrument used in the standard methods-hybrid respirometer, has high automatic level and friendly user interface which simplifies the respirometry. So the suggested standard methods are practical.(10) According to the suggested standard methods, the influent COD of a wastewater treatment plant in Chongqing, China, is characterized.

9提出一套表征城市污水COD组分的标准化方法建议，其特点在于：①以呼吸测量作为RBCOD和SBCOD的测量方法，与以往以物理化学方法为主的做法有着本质区别；②对原水直接进行分析测试来获得SI组分，不受溶解性惰性产物的干扰；③考虑了污水中活性异养微生物组分的单独测量；④所依赖的核心仪器-呼吸测量仪具有很高的自动化程度和简单友好的用户界面，使原本复杂的呼吸测量实验及其结果的分析统计简单化，所建议的标准化方法具有很好的实用性。

The experiment was carried on in 2004-2006 year in the Shandong Longkou and the Shandong Institute of Forestry Science courtyard, Research was carry on how to reduce the cost in view of the low reproduces coefficient, low rootage and transplanting, not formed the scale to produce, the perfect group cultivates and the seedlings technical system to the factorization to carry on to the optimized so the technical system effectively reduce the single cost.

本试验于2004-2006年在山东省龙口复发中纪和山东省林业科学院院进行，针对组织培养过程中繁殖系数低、生根率和移栽成活率低，没有形成规模化生产，达不到规模效益等问题造成生产成本高的原因进行研究，完善组培苗的生产技术工艺，对苹果砧木工厂化育苗技术体系进行了优化调整，建立起了一套实用性强的高效工厂化育苗技术体系从而有效地降低单株成本。

This method is right radiation network, through Y-△ commutation makes the spur track number of each node is from beginning to end 1, assure to won't produce infuse element in iteration process thereby, attain ideal optimize number effect, and small, program writes the workload of this method simple, have stronger practical.

该方法对辐射型网络，通过Y-△变换使各节点的支路数始终为1，从而保证在迭代过程中不会产生注入元素，达到理想的优化编号效果，且该方法的工作量小、程序编写简单，具有较强的实用性。

Further more, most analysis lacks sufficient statistic data as a strong support.Most of the analysis refer to or directly quote other foreign works and therefore the conclusions are less practical and convictive.

尤其重要的是，由于我国对雇员流动的数据统计资料不足，这些分析大多参照或引用国外同行资料得出，因而其结论实用性、说服性不强。
