有限責(zé)任公司是一家全國(guó)性的綜合類證券經(jīng)營(yíng)機(jī)構(gòu)，總部位于上海，目前在全國(guó)范圍內(nèi)擁有48家證券營(yíng)業(yè)部、 11家證券服務(wù)部，營(yíng)業(yè)網(wǎng)點(diǎn)數(shù)量在全國(guó)100多家專業(yè)券商中位居前10名。 - Some features of the engineering control network demand special applications of gps in road and bridge engineering , for example , particular requirement of accuracy on some aspect that results in distribution of net points and sometimes bigger height difference of points , consideration of staking out in construction in the design of engineering control network , application of independent engineering coordinate system , and use of engineering mean height surface as the projection surface of computation
由于工程控制網(wǎng)的一些自身特性，如施工控制網(wǎng)要考慮施工放樣的方便，或某一方面精度的特定要求，網(wǎng)點(diǎn)分布不夠均勻，點(diǎn)間高差有時(shí)較大；采用工程獨(dú)立坐標(biāo)系，并且往往以工程平均高程面為計(jì)算投影面等等，使得gps在路橋工程中的應(yīng)用也有一些特殊性。 - In this article , we use idea of turning dispersion into convergence and put all the well ' s points into the same unit net to think about it . and answer three questions of the distribution of well drilling by the way of searching for groups of points . fincite - step - searching underthe condition of translationg fcoordinate system or revolving coordinate system . to first question . we find two algo - rithms and make use of data that is given to find the solution . we seek coorlinate of net point is co . 361 , 0 . 461 ) and mostly four old well ' s points are utilized at the same time by first algorithim , which are no . 2 , no , 4 , no . 5 , no . 10 . by second algorithm , we rechon the coordinate of net point is co . 390 , 0 . 505 ) . and that mostly four old well ' s points are utilizld which are no . 2 , no . 4 , no . 10 . to second question , we turn it into the first question by angling awt the center of net point . we seek that mostly six old well ' s points are utilized at the same time , which are no . 1 , no . 6 , no . 7 , no . 8 , no . 9 , no . 11 , when net is angled 0 . 78 radian . and net point is translated to ( 0 . 75 , 0 . 076 ) ( at nwe coordinate system ) . to third question , wefind a necessary and sufficient condition and affer algorithms , at last , we analyse algorithms
運(yùn)用化分散為集中的思想,把所有的井點(diǎn)都放在同一個(gè)單位網(wǎng)格內(nèi)考慮.在坐標(biāo)可平移、旋轉(zhuǎn)的條件下，利用尋找點(diǎn)群、有限步驟搜索法，對(duì)鉆井布局的三個(gè)問(wèn)題進(jìn)行了解答.對(duì)問(wèn)題一，給出了兩個(gè)不同算法.并對(duì)題目提供的數(shù)據(jù)進(jìn)行了求解，算法1得到的結(jié)點(diǎn)為（ 0 . 361 , 0 . 461 ） ,最多有4個(gè)舊井點(diǎn)被同時(shí)利用，它們是第2 、 4 、 5 、 10個(gè)井點(diǎn);算法2得到的結(jié)點(diǎn)為( 0 . 390 , 0 . 505 ) ,最多有4個(gè)井點(diǎn)被利用,它們是第2 、 4 、 5 、 10個(gè)井點(diǎn).對(duì)問(wèn)題二，以結(jié)點(diǎn)為中心旋轉(zhuǎn)一定的角度后，歸結(jié)為問(wèn)題一進(jìn)行求解，求解結(jié)果為當(dāng)網(wǎng)格傾斜角為0 . 78弧度（相對(duì)原坐標(biāo)系） ，結(jié)點(diǎn)平移到（ 0 . 75 , 0 . 076 ）點(diǎn)(在新坐標(biāo)系下) ，可被同時(shí)利用的最多舊井點(diǎn)為6個(gè)，它們是第1 、 6 、 7 、 8 、 9 、 11個(gè)井點(diǎn)，對(duì)問(wèn)題三，我們給出了充要條件，并給出了算法.最后還分析了算法的優(yōu)劣性
