解釋
擴張距離-
Due to the superiority of long - distance audio - visual education, under " science and education strengthening national power " and " developing education, increasing the citizens " scientific literacy level " of national policy ' s leading, in the new history period, the long - distance audio - visual education will take on the duty of people education, quality education, creativity education etc. and under the state of the nation it will exerting superiority that any medium does not for rapidly increasing people ' s scientific li teracy level, widely spreading science and culture, scientific idea, science consciousness
遠程視聽教育以其良好的物質技術基礎，在國家「科教興國」和「普及教育、提高全民素質」政策的指導下，將在新的歷史時期擔負起全民教育、素質教育和創新教育等方面的責任，發揮其他任何媒體不可比擬的優勢，對我國全民素質的提高、科學文化的普及、科學觀念和科學意識的深入人心有著不可低估的作用。 -
Spread spectrum code emitted by navigation station has correlative operation with the signal produced by receiver, through measuring the place of maximal correlative function, we can measure the spreading time of the navigation station ’ s signal, so we can measure the distance between navigation station and receiver
區域導航利用導航臺發射的擴頻碼與接收機產生的本地信號進行相關運算，通過測量相關函數最大值的位置，來測定導航臺信號傳播時間，從而測定導航臺到接收機的距離。 -
These kinds of ? tronger ? algorithms do not need to retrieve correspondence and branching problems. the contour - spreading algorithm is proposed to calculate distance field quickly within the complexity 0 ( n ). the intermediate surface is generated by linear approximation, while in conventional methods, it is tiled between a designated layer of contours and the original lower slice or upper slice of contours
和傳統方法比較，它們生成的曲面都是精確通過采樣點，但是對于中間曲面的生成（在有分枝問題和對應問題時）方式不同，傳統方式是指定中間層的位置，在中間層按一定方式生成一個輪廓線，然後分別與上下層進行曲面鑲嵌，而基於距離場技術的方法則是通過線性插值的方式來產生中間曲面。 -
During designing hardware circuit, we have used the supreme limitation to raise driving - ability and raise the distance of measurement to returning ware by taking some measurements just like multi - polar enlarging, according to the ultrasonic characteristic of index attenuation when it ' s spreading because we need to measure longer distance ( from several meters to dozens of meters )
在硬體電路的設計中，由於需要測的距離較長（幾米到十幾米） ，針對超聲波振幅在傳播時呈指數衰減的特性，最大限度地提高驅動能力，對回波進行多級放大，達到了設計要求。
