And with the strongly polar activated water, even the amount of cement ia decreased to 10 percent, the mechanical performance of the concrete is improved too. of course, the increase rate is different with different parameters, these parameters include discharging energy, discharging times, the distance between the two electrods, and so on
雖然受實驗條件所限，作者未能做大量的實驗並進行全面的分析，但所有實驗數據都顯示出電液壓脈沖方法能提高混凝土的抗壓強度； 2 、利用強極性活化水攪拌混凝土，在節約水泥量達10 %的情況下，其抗壓強度仍有一定程度的提高。 -
Although it was in an unparalleled superiority, america ' s hegemonism policy falls into dire straits from either itself or the tendency of globalization and multi - polar international society. but at first, we must confess that there is still a distance between american ' s current forces and the attempt to be hegemony in the world
《 a碩士學位論文wmairsdiesis盡管美國有著無可比擬的實力優勢，但是不管是從美國自身的角度還是從全球化和多極化的國際社會發展趨勢來看，美國的霸權主義政策都面臨著困境。 -
Then, the minimum circumscribed circle and shape principal orientation of the object region are calculated ; and the object region is divided into some blocks in the polar coordinate, which uses the center of the minimum circumscribed circle as the origin and the direction of the shape principal orientation as the direction of the polar axis, and the features of all subblocks are extracted to compose shape histograms and then smoothed ; then, combined with global features to synthetically represent the content of the image ; finally, a new image similarity is used to compute the distance between images
首先對商標圖像進行預處理，得到規則二值圖像;計算目標像素的最小外接圓和圖像的形狀主方向;在以最小外接圓圓心為原點、形狀主方向為極軸方向的極坐標中將圖像分塊，提取各子塊特徵，構成形狀直方圖並平滑處理;再結合全局形狀特徵來綜合表示圖像內容;最後採用新的相似性度量方法計算圖像間距離，實現商標圖像的準確檢索。 -
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。
