The information integrated pattern based on PDM/PLM in the course ofmanufacture is put forward. Under the constraints of building CAPP platform, thearchitecture of CAPP platform is established. The models of decision making andfunction for process planning are given. Then the development means of CAPP basedSmarTeam are extracted.3. The structure of modular product life cycle is established. Toward the divisionand planning of the General Modules oriented product family, theCAD/CAPP integrated model of flexible module based on feature and CAD/CAPPmapping model based on process planning match board are set up. The keytechnologies of Solidworks/SmarTeam/CAPP integration are studies.4. From the point of view of process match board and step match board, theprocess of creating to process planning match board is studied. As an example, themachining process planning of up beam of hydraulic press machines is used tointroduce the establishment of process planning match board by means of inferencebased on expert knowledge. The organize model about the process planning matchboard oriented product family is brought forward.5. The multi-decision methods of CAPP system based on analytic hierarchy aregiven.. On the basis of uniform data model, the sub-machining process planning ofpart is auto-created by means of analytic hierarchy, The step decision methods basedon AHP is put forward.6. For the design/manufacture information in the course of product life cycle, thetree structure based on Object-Oriented and static model based UML are founded. Themethod of establishing design/manufacture information management system isbrought forward. The commercial PLM software—SmarTeam is regarded asdevelopment platform, on basis of which, the design/manufacture informationmanagement system is built, and the multi-view mapping technique ofdesign/manufacture information model is studies.7. A computer-aided CAPP platform based on PDM/PLM is founded, and itsstructure, function, work flow is illustrated. Some example of the system areintroduced.

Because the strength of springwood was very low, the strength of board which included more springwood was low. The main reason why there was no difference in wet compressing shear strength between quarter-sawn board and flat-sawn board was that quarter-sawn board had a lot of pits on radial cell wall and in flat-sawn board xylary rays were transversely cut and left a lot of pores which provided a kind of tunnels for water.

造成柞木径切板的反复煮沸压缩剪切强度与弦切板的反复煮沸压缩剪切强度没有显著性差别的主要原因是柞木细胞壁径面上的纹孔很多，而弦面上的木射线在经刨削后是横断的，留下许多孔隙，这使得弦径向均有成为水分通道的孔隙，造成柞木径切板的反复煮沸压缩剪切强度与弦切板没有显著性差别。

Edit in what defend Jian measure respect, the main opinion that gathers before this includes: It is to suggest not to lengthen the orgnaization that protect Jian to doing poineering work board the superintend and director of the company guides period, card inspect can think through research, because do poineering work board company dimensions is relatively lesser, management stability is relatively inferior, lengthen superintend and director to guide appropriately period be helpful for active and reliable roll out do poineering work board, reason did not grant to adopt; 2 it is to suggest exempt does poineering work board company IPO in those days namely the responsibility of the person that protect Jian of deficit, card inspect can think via research, although do poineering work board the company is managed not stable, but if the company appears on the market in those days with respect to deficit, can produce baddish effect to the market, because this cannot loosen the responsibility of pair of people that protect Jian to find out; 3 it is to suggest to unlock person of the delegate that protect Jian to sign odd number to measure limitation, meeting general is keeping next card watch in be being arranged related Jian system, give further research, hear opinion of orgnaization of Jian of be bailed out, make arrangement jointly.

在保荐办法的修订方面，此前收集到的主要意见包括：一是建议不要延长保荐机构对创业板公司的督导期，证监会经过研究认为，由于创业板公司规模相对较小，经营稳定性相对较低，适当延长督导期有利于积极稳妥推出创业板，故未予采纳；二是建议豁免创业板公司IPO当年即亏损的保荐人责任，证监会经研究认为，尽管创业板公司经营不稳定，但如果公司上市当年就亏损，对市场会产生较坏的影响，因此不能放松对保荐人的责任追究；三是建议放开保荐代表人签单数量限制，下一步证监会将在保荐制度相关安排中予以进一步研究，听取保荐机构意见，共同做出安排。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
