By the end of 1995 china had set up 175 zoological gardens and zoological exhibition sites in public parks, 227 artificial breeding centers for wild animals, more than 60 large botanical gardens and 255 wild plant gene and cell banks to ensure the continuation of rare and endangered species of plants and animals, including the giant panda, chinese alligator, chinese sturgeon, white - flag dolphin, manchurian tiger, crested ibis, cathay silver fir, dovetree, cycas revoluta and camellia chrysantha tuyama
到1995年底，中國共建動物園和公園動物展區175個、各種野生動物繁殖中心（場） 227個，建立大型植物園60多個、野生植物引種保存基地255個，使大熊貓、揚子鱷、中華鱘、白暨豚、東北虎、朱? 、銀杉、珙桐、蘇鐵、金花茶等珍稀瀕危動植物得到保護。 -
My father was endeavoring to pierce with his eager looks the remotest verge of the horizon, examining attentively every black speck which appeared on the lake, while my mother, reclining by his side, rested her head on his shoulder, and i played at his feet, admiring everything i saw with that unsophisticated innocence of childhood which throws a charm round objects insignificant in themselves, but which in its eyes are invested with the greatest importance. the heights of pindus towered above us ; the castle of yanina rose white and angular from the blue waters of the lake, and the immense masses of black vegetation which, viewed in the distance, gave the idea of lichens clinging to the rocks, were in reality gigantic fir - trees and myrtles
我的父親坐在一個大洞前面，目光凝視遙遠的地平線，聚精會神地仔細觀察湖面上的每一個黑點，我母親靠在他身邊，頭枕著他的肩胛，而我就在他的腳邊玩耍，帶著天真的好奇心眺望著巍然屹立在地平線上的賓特斯山，那白皚皚稜角分明從蔚藍的湖面上高高聳起來的亞尼納堡，以及那一大片黯黑青翠從遠處看以為是附著在巖石上的苔蘚實際上卻是高大的樅樹和桃金娘。 -
Based on the normal equation algorithm to fir system identification and wavelet iteration, a method to estimate the wavelet from the third - order cumulant of field data is developed. due to the fact that higher order cumulant retains the phase information of the signal, and can suppress the gaussian noise ( color or white noise ) naturally, we can improve the time resolution via inverse filtering the wavelet estimated
本文在基於高階累積量的fir系統辨識基礎上，利用觀測信號的三階累積量對探地雷達子波進行估計，提出一種簡單的迭代演算法改善了波估計性能，據此進行反褶積，改善反射信號的信雜比和時間解析度。
