【正文】 這種類型的事故分析是通過分析事故的共組或子群來開展。然而研究人員的興趣較少集中在這個最后的結(jié)果本身，而是多在進程更多的結(jié)果（或不結(jié)果）的事故。另外，在雙向表，卡方總可以分解成零件表互動的作用。該程序的描述，也可以使用，如果發(fā)生意外乃根據(jù)數(shù)的特點找到有前途的安全目標。對于這些時期的總和泊松率則等于為這些地方的泊松率的總和。信息的主要來源是國家數(shù)據(jù)庫及其統(tǒng)計學(xué)處理系統(tǒng)。必要的增加數(shù)據(jù)類型也能更好的解釋交通中存在的危險因素。事故分析是應(yīng)用非常有限的分析，是前瞻性分析和回顧性分析，能夠?qū)π麻_發(fā)的交通安全系統(tǒng)和特殊過程的安全措施進行評價。（5）有限元模型的建立，在激光焊接過程中的冷卻速率的情況下預(yù)熱的20和40倍以上的馬氏體形成的臨界冷卻速度。斷裂路徑（通過HAZ）此標本圖14中可以看出（D）。在焊接熱影響區(qū)的亞區(qū)的顯微硬度分布與焊后熱處理之前，在熱影響區(qū)的亞區(qū)的屈服強度一致，如Lee等人的工作報告。MS（馬氏體開始）SA508鋼溫度大約是420176。在隨后的快速冷卻過程中，任何新產(chǎn)生的奧氏體將被淬火形成馬氏體。C／min（15176。冶金不同分帶的微觀組織轉(zhuǎn)變熱分析的結(jié)果進行了驗證，發(fā)現(xiàn)與實驗結(jié)果吻合良好?？諝獾膶α鲹Q熱系數(shù)， [ 38 ]。在三維實體模型，利用ANSYS軟件生成的38337個節(jié)點和41040個單元（）。解理斷裂被證實在這些基礎(chǔ)材料和激光焊接試件的斷裂與低吸收的能量在?40176。C和45 J在?20176。為了highlight的散射的結(jié)果對激光焊接specimens，這三個測試的結(jié)果是市場在每個溫度圖13和圖14。所有的拉伸破壞發(fā)生在遠離焊接區(qū)域的。在FGHAZ組織包括汽車回火馬氏體細晶粒馬氏體。接頭可以分為幾個不同的區(qū)域，如冶金，熔合區(qū)（FZ）在中心，熱影響區(qū)（HAZ）與基體材料（BM）。使用氬氣保護氣體，氣體流速為12升/分鐘和8升/分鐘，分別保護使用的頂部表面和在焊縫側(cè)的焊縫。缺口位于熔合區(qū)，以測試激光焊接樣品的焊接金屬的韌性。分別。根據(jù)參考文獻[ 22 ]計算調(diào)查的鋼的CE，并給出：從表1看出，SA508 CE 。冷卻速率在不同的子區(qū)域?qū)⒋_定相變發(fā)生在連續(xù)冷卻轉(zhuǎn)變組合焊接過程中（CCT）在調(diào)查中對鋼圖。[ 16 ]報道常規(guī)看到3 kJ /毫米每通過一個熱輸入SA 508級3鋼的焊接。工業(yè)用新方法在有限元程序LSDYNA 971實現(xiàn)關(guān)鍵詞： 核鋼穩(wěn)壓器 壓水反應(yīng)堆 反應(yīng)堆壓力容器 結(jié)構(gòu)完整性 焊接韌性SA508鋼通常用于民用核反應(yīng)堆的關(guān)鍵部件，如反應(yīng)堆壓力容器。這標志著一個管理問題，也許可以通過引進更靈活的分區(qū)和增加地方政府的責(zé)任范圍和土地的財產(chǎn)權(quán)來解決。我們獨特的數(shù)據(jù)集包含社會經(jīng)濟、人口和空間。HTTP：// OPENCV。的z校正圖像是從z中減去坐標XIR的計算等式所。我們得到了N次測量，正從深度圖像全部校準點，圖7（d）。我們聯(lián)想Kinect的坐標系與紅外相機，因此得到RIR=我和CIR=03D點XIR構(gòu)造從測量[X，Y，D]在深度圖像通過并投射到RGB圖像作為其中，存款保險計劃是由等式給出的失真函數(shù)。幾個實驗對象不同結(jié)果形狀如表1所示。圖3（a）。我們建立在以前的工作之上，并設(shè)計了一個精確的校準程序的基礎(chǔ)上考慮的幾何模型，以及作為一個額外的校正程序會計“學(xué)習(xí)”對于剩下的非建模誤差。我們通過整合演示的Kinect校準的功能它變成一個SFM管道，其中三維測量從運動的Kinect被變換成一個共同的坐標系統(tǒng)通過從比賽計算相對姿態(tài) 彩色攝像機。（IR）投影儀，紅外照相機和RGB攝像頭。 深度解析圖3（b，c）表示深度分辨率的函數(shù)距離。的深度圖像目標是通過其白邊表示。2，第3顯示內(nèi)部參數(shù)和圖圖6顯示效果在攝像機的扭曲。與單反一對立體聲（左，右）與3D完全校準重建在平面校準目標點。的標準偏差殘差下降。 Michael Kazmin2 Published online: 7 July 2015 International Atlantic Economic Society 2015 JEL Classification This research note explores the link between farmland conversion and existing land regulation in conclude that land regulation is lagging the new market trends in the transition economy of market forces continue to penetrate the economy, apparent managerial and statutory problems with regard to local landuse planning and regulation preclude more effective use of to the need for attracting investment in agriculture, the Russian Ministry of Science and Education provided funds for our research project that involves primary data collection and econometric analysis of the interdependencies between governmental policies and farmland unique dataset contains socioeconomic, demographic and spatial geographic 2010 data for 39 municipal districts in the Moscow metropolitan econometric analysis of this data set is used to explore the relationship among farmland quantity, its assessed value, the share of privatized farmland, farmland tax,and landuse zoning in the simultaneous equations the Russian market for real estate has developed quickly, the market for agricultural land is still deals are limited, partly because of the lingering uncertainty about farmland property stateowned farmland is still Moscow regional data suggest a strong positive relationship between the fraction of privatized farmland and farmland acreage, although the fraction of individually and collectively privatized farmland is only 57 %.The direct sale of farmland to foreigners is prohibited decreasing potential foreign investment as a result, the area occupied by agricultural lands has been steadily decreasing and deteriorating in the period 1990 to 2005, tillable lands in Russia have shrunk by million hectares( % of tillable lands).Lacking experience and adequate knowledge, local governments are stuck with the land conservation policies available to the former particular, in an attempt to contain the loss of prime farmland, the regulators retain old landuse zoning laws prohibiting the change of land , strong development pressures and widespread corruption often annihilate the desirable effect of results of our econometric analysis indicate that the proximity to Moscow city and population growth both have a significant negative effect on the amount of farmland, even in the strictlyzonedfor agriculture districts, suggesting strong urban pressure in the capital region of estimated elasticity of farmland acreage with respect to population growth is ? corrupt practice of illegal changes in land status is reflected in the fact that the lands still classified as farmland in the Federal Register of Land are turned into residential or industrial signals a management problem which could be perhaps resolved by the introduction of more flexible zoning and an increase in the range of responsibilities of local governments and their property rights to other economic instrument indispensable in land policy, land assessment, is also based on the former practices of the Communist period following a federally mandated general formula that takes into account soil productivity criteria, topographic features of the landscape, and the presence of irrigation, but still has little in mon with the market price of the agricultural land tax is calculated as the percentage of the assessed value of farmland, which is often below its real market value, local authorities are not interested in developing local agricultural infrastructure or increasing agricultural land base because they will not be able to reap any significant tax benefits from with the low federally mandated upper limits on tax rates( % of the assessed value of agricultural and residential lands)this leads to insufficient local tax revenues and overreliance on intergovernmental to our data for the Moscow region, although localities tend to impose the maximum allowable tax rate, the average share of land tax revenues in local budgets is a mere 5 %.It is not surprising as the average assessed value of farmland across municipalities is 1000 times less than the ongoing average sales price, according to data we insignificant local land tax revenues caused by the underestimated land value lead to insufficient local infrastructure investment, which further suppresses the value of farmland and hastens
