Concurrent Engineering absorbs computer technique , database technique , network technique under the support of CAD, CAM, CAPP and CAE, considers conception form , scheme analyses , detail design, production, after service , production rejects all factors, resolves effetely lots of defects such as difficulty of data exchange , design changing frequently , cost high, long cycle for design and so on.

摘要并行工程是在CAD，CAM，CAPP和CAE等技术支持下，吸收了当前迅速发展的计算机技术、数据库技术、网络技术，在设计时综合考虑产品开发中的概念形成、方案分析、详细设计、生产制造、售后服务、产品报废等所有因素，有效解决了系统之间数据交换难，设计更改频繁，成本高，设计周期长等缺点。 DFM是并行工程的关键技术之一，在设计一开始就把制造系统的因素添加到设计过程中去，并从制造可行性的角度对设计进行分析评价，使设计满足制造要求，降低加工时间和生产成本。

And this article divides the farmers into three grades in the point of qualitative and quantitative views, and according the principle of econometrician, using the way of Oaxaca analysis, choosing and analyzing the controllable variables in the maize process, in order to find the main ingredients which forming the difference about the behaviors of maize producers based on the different maize grossing zones.

本文通过对南北三省农户玉米生产的投入和产出情况进行实地调查，首先比较分析了不同收入等级农户、不同地区农户和不同土地等级玉米生产的成本和收益情况；然后从定性和定量的角度将农户分为三个等级，再从农户等级和不同玉米种植区的角度出发，根据计量经济原理，运用OAXACA分解分析方法，选择农户玉米生产中的可控制变量对其进行分析，以找出形成农户玉米生产行为差异的主要影响因素。

针对目前小合成氨厂碳丙脱碳存在的问题，详细分析了影响碳丙脱碳装置正常生产的因素，总结了 90年代以来人们在解决生产实践中诸多问题的经验和方法，对碳丙脱碳工艺作了总结与评述。

The conclusions are drawn as follows: the region is lacking of the social consciousness and atmosphere of non-polluted vegetable standardization production and consumption; the quality and efficiency of production is low; the marketing mechanisms for "high price and good quality" is not built yet; the systems of supervision and measure mechanisms for non-polluted vegetable is not established; extension service and industrialization governance can not be offered for the greenhouses vegetable production; the production scale and trade mark for local products need to be perfected; farmers low quality in science and technology and so on.

结果认为，主要存在着无公害蔬菜标准化生产和消费的社会意识和氛围不浓，产品质量和生产效益相对较低；蔬菜"优质优价"的市场机制还未建立，蔬菜质量监督检测机构尚未形成；日光温室蔬菜无公害标准化生产的推广服务体系尚未建立，产业化组织机制发育不健全；日光温室蔬菜生产规模小，品牌产品缺乏；农民文化水平偏低等五个方面的制约因素。

To this day , a lot of innovative researches focus on the production of the bamboos, the biological and abiological factors of restricting the bamboos' production, the nutrient cycle of the forest system, the relationship between the bamboos' clonal growth and regeneration of the system, the hypothesis for the bamboos' bloom mechanism etc. But the results were too confused, make the ecological process of the bamboo forest be unclear, and this is not enough to conserve panda and its habitat.

目前，各专家学者围绕大熊猫主食竹的生物量生产、制约大熊猫主食竹生物量生产的生物因素和非生物因素、大熊猫主食竹群落系统的养分循环、大熊猫主食竹种群的克隆生长与群落更新、大熊猫主食竹开花机理假说等方面作了大量的研究，但研究结果还具有许多不确定性，这对大熊猫主食竹群落系统生态学过程的深入了解还非常不够，同时也很难满足大熊猫及其栖息地保护的需要。

The finding of our research indicates that the different institutions of land create different incentive to the persons who engage in the agriculture. At the same time, the change of benefit space is caused by the movement of price and finical impacts on the activity of farmers. Hence, the change of institution plays an important role in the agricultural economic growth after China' s reform and opening.

分析的结果是，在农业生产中实施的不同土地制度对从事农业生产的人们形成不同的激励，而在农业生产和经营中推行的价格、财税制度变革又以形成的利益空间影响从事农业生产和经营的人们的积极性，因此，制度变迁是中国改革开放后农业增长的决定性因素。

Control factors of VRLAB in manfacturing process were discussed, and the reasons for control the factors were analyzed. The results show that iron in lead should be control in 0.000 7%, oxidizability of lead should be controlled in ±5% require...

通过查阅文献并结合生产实际，对VRLAB生产过程中需要控制的因素加以论述，并论述了控制这些因素的原因，指出铅粉中铁杂质含量宜控制在 0 。0 0 0 7%以内，铅粉的氧化度应控制在要求指标的± 5 %以内，灌酸密度应控制在技术要求的± 0 。0 0 5g/cm3 以内。

I.S.P is the typical complex and continuous production process.
