To me , a badly optimized program means that it has a bug 對(duì)于我來(lái)說(shuō),一個(gè)優(yōu)化不好的程序就意味著該程序有bug 。
With the relatively advanced software , an optimized program was worked out to optimize the drawing direction 并利用較先進(jìn)的軟件,編制了優(yōu)化程序,對(duì)拉伸方向進(jìn)行優(yōu)化。
Finally , data acquisition , error calculus and error compensation are carried out by means of optimizing program designing , which prepare for the subsequent analysis adequately and reliably 最后通過(guò)軟件優(yōu)化編程,完成了系統(tǒng)的數(shù)據(jù)采集、誤差計(jì)算及誤差補(bǔ)償。為后續(xù)處理做了充分、可靠的準(zhǔn)備。
In the articulation space , we optimize time ; form module by adopting b spline curve , which including speed and acceleration constraint . we make use of mainly compound form optimizing program to find optimal solution 在關(guān)節(jié)空間中,針對(duì)時(shí)間的進(jìn)行優(yōu)化,采用b樣條曲線來(lái)構(gòu)建優(yōu)化軌跡模型,把速度和加速度約束因素包括進(jìn)來(lái),利用復(fù)合形的優(yōu)化程序?qū)ぷ顑?yōu)解,符合要求的優(yōu)化精度。
So it is appears important to analyse capability of this structure , the people can compute all kinds of complex structure ’ s response under different sorts of exact load on current software , but the source program of the computing question , which is “ black box ” , on the contrary , fepg can get the source program , which can provide preference for the optimization of structure , even embed in the optimizing program and save much time of compiling program , linking to ga to identify the load can get the good result . so the problem is solved to alleviate the deadweight and the optimize design of the structure , as well as improve its secure capability 對(duì)格柵結(jié)構(gòu)進(jìn)行力學(xué)分析就顯得至關(guān)重要,盡管利用通用有限元軟件能夠計(jì)算結(jié)構(gòu)承受任意可以準(zhǔn)確描述的載荷作用下的響應(yīng)問(wèn)題,但內(nèi)部計(jì)算卻是“黑箱”操作,利用fepg可以得到計(jì)算源代碼,能夠?yàn)閮?yōu)化程序提供參考甚至可以嵌入其中,節(jié)省繁瑣的有限元計(jì)算編程內(nèi)容,結(jié)合遺傳算法進(jìn)行載荷重構(gòu),往往會(huì)收到很好的效果,這就解決了由于工作環(huán)境比較復(fù)雜,引起響應(yīng)的載荷難以直接測(cè)量得到的難題,從而為結(jié)構(gòu)優(yōu)化設(shè)計(jì)和提高安全性能的提供了保障。
Then , depended on the expressing / feature / optimizing module under ug software , the compensating area parameters on the out place of side - plate for balancing action could be realized , and at the same time the close connecting parameter optimizing with 3d modeling could be carried out as well , finally the results from optimizing program were coincident with the parameters of the imported pumps 進(jìn)而利用ug軟件的函數(shù)表達(dá)式和特征建模及優(yōu)化模塊,實(shí)現(xiàn)齒輪泵補(bǔ)償面基本參數(shù)的優(yōu)化設(shè)計(jì)和軸套(側(cè)板)三維參數(shù)模型自動(dòng)生成的無(wú)縫連接,所得結(jié)果與引進(jìn)泵的基本參數(shù)比較吻合。
In china , the relic industry began to realise the importance of informationization recently , now facing the challenge of the new century it needs informationization , so relic bureau of shanxi province and beijing taijihuaqing information system ltd developed cooperatedly the relic information colligation platform . basing designing and developing that platform , the question for study has made some practice and study on some facts , such as software unified process , visualized modeling , optimizing program , the technique data mining and data warehouse 我國(guó)的文物行業(yè)信息化起步比較晚,面對(duì)新世紀(jì)的挑戰(zhàn),迫切需要走上信息化的道路。為此,山西省文物局、北京太極華青信息系統(tǒng)有限公司聯(lián)合開(kāi)發(fā)了山西文物綜合信息平臺(tái)。本課題在設(shè)計(jì)與開(kāi)發(fā)本系統(tǒng)的基礎(chǔ)上,從統(tǒng)一軟件開(kāi)發(fā)過(guò)程、系統(tǒng)的可視化建模、程序優(yōu)化技術(shù)、數(shù)據(jù)挖掘技術(shù)、數(shù)據(jù)倉(cāng)庫(kù)技術(shù)等幾個(gè)方面做了相關(guān)的研究與實(shí)踐。
It helps to know the status of program running and program communication . it gives intuitive references to find out performance bottlenecks and advices to optimize programs . to validate the applicability and validity of the system , the parallel program performance of combustion processes of liquid rocket engine is monitored and analyzed by using the analysis system 為了驗(yàn)證系統(tǒng)的實(shí)用性和有效性,運(yùn)用該分析系統(tǒng)在機(jī)群上對(duì)液體火箭燃燒過(guò)程仿真程序進(jìn)行了監(jiān)測(cè)與性能分析,預(yù)測(cè)了程序的執(zhí)行和通信時(shí)間,定位了該程序的性能瓶頸,給出了優(yōu)化建議。
Valuable conclusion in engineering are drawn for practical design . the method of getting reasonable prestress degree for suspendoem which is restricted by intergral stability was discussed . optimizing programs are developed with the axis force and joint displacement of upper dome as object function respectively , the effective method of prestress degree for suspendoem which is 探討了穩(wěn)定約束的弦支穹頂鋼索合理預(yù)應(yīng)力度的優(yōu)化方法,分別以網(wǎng)殼桿件內(nèi)力、節(jié)點(diǎn)豎向位移和節(jié)點(diǎn)垂直向下位移為目標(biāo)函數(shù)編制了優(yōu)化程序,得到了整體穩(wěn)定約束的弦支穹頂結(jié)構(gòu)確定鋼索預(yù)應(yīng)力值的可行方法。
