作品精心設計，巧意雕琢，一對栩栩如生的鴛鴦雕刻細致生動，似在水中追逐戲嬉，喁喁私語的甜蜜樣子，真是羨煞人也，兩只鴛鴦的背上分佈著些許綠白色，更顯精美迷人，作品上面巧用美艷的翠色精心巧雕在精美大氣的荷葉，葉脈細膩流暢，工藝細致自然，美艷的翠色分佈合理精湛，荷葉中間巧用黑色翡翠摘雕出兩只栩栩如生的小青蛙，摘色干凈自然，更顯生動逼真。The use of interferometer to detect and analyze laser radiation is well known, but when the intense ratio of the laser radiation to the background natural light radiation is too small, the laser radiation cannot be detected. a novel more sensitive method for detect of wideband weak incident laser in strong background noise is introduced in this paper. the optical unit uses two wedge interferometers and two line array detectors. the incoming light radiation is divided into two beams and through the interferometers
在被動激光偵察告警中，對微弱脈沖激光信號的探測是一個難點。當探測距離相當遠或視場內接收的背景光輻射很強時，脈沖激光信號到達探測器的能量很小，會淹沒在強大的背景光信號中而探測不到。本論文提出了一種探測微弱脈沖激光信號的方法，可對強烈背景光中的激光威脅信號進行探測和告警，並給出其波長參數。In this paper the methods of chronically implanting microelectrodes, combined electrophysiology with behavioral learning in vivo, were used to study the effects of low frequency stimulation ( lfs ) of the dorsal norepinephrine bundle ( dneb ) on the learning - dependent long - term potentiation ( ld - ltp ) at the hippocampal mossy fiber synapses onto ca3 pyramidal neurons. paired - pulse technique at the intervals of 75 - ms, 150 - ms and 300 - ms was used as the test stimulation. the results showed as follows : 1
本實驗運用慢性微電極埋植技術和電生理學結合行為學的在體研究方法，以配對脈沖檢測（間隔分別為75ms ， 150ms ， 300ms ）為檢測手段，探查了低頻（ 1hz ， 5hz ）刺激去甲腎上腺素背束（ dorsalnorepinephrinebundle ， dneb ）對大鼠苔蘚纖維- ca3 （ mf - ca3 ）突觸上習得性長時程增強（ learning - dependentlong - termpotentiation ， ld - ltp ）及動物行為習得的影響。Xikuangshan type copper ore deposit named those fe - cu deposits hosted in yinmin formation, kunyang group, which located in kunyang rift valley and the edge of southwest yangzi platform. the best example is xikuangshan allotment, luoxue ore area, dongchuan, yunnan. the type deposit spread in south kunyang rift valley, include dongchuan, wuding - luoci, yuanjiang, yimen, huashengping, hongmenchang and so on
稀礦山式銅礦是指賦存在昆陽群因民組地層中的銅鐵礦床，其大地構造背景屬于元古代裂谷帶，大陸裂谷是超大型銅等多金屬礦形成和分佈的有利環境，在裂谷下部常發育異常地幔和巖漿源，裂谷空間上的多層次性使礦床具有明顯垂向分帶特徵，其演化時間的長期性、脈動性和繼承性便於多期成礦作用相互疊加、礦質的高度聚集。In frequency - domain, the background mode that has the most contribution to the buffeting energy of the structure is calculated using the background modal analysis method, thus the rms of the dynamic responses of long - span grid roofs is obtained. on the other hand, the rms of the dynamic responses is also obtained by direct integral method in time - domain. after the comparison of the results of two methods, several important conclusions can be made
在頻域內，採用背景模態分析法，通過計算得到對結構振動能量貢獻最大的一階背景模態，從而得到結構脈動響應的均方根值；在時域內，採用直接積分法求出結構響應的時間歷程，並且通過統計，同樣得到結構脈動響應的均方根值。This specimen of a pigeon, being dissected along the middle line of its belly, whose chest and abdoment walls, chest bone, right leg, right side chest muscle and its artery and vein, as well as the portion of liver being removed, the left side chest muscle being turned outward with all intestines being pulled outside, was fixed on the board
本標本沿鴿腹部中線剖開，切除胸腹壁、胸骨、右後肢等，及部分肝以及右側的胸動、靜脈和胸肌；左側胸肌翻向外側，大小腸從體腔內拉出體外，標本背向襯板固定。The national highway of hurong is a backbone artery of the national west - east direction, and the traffic main artery of the development of the west regions, following the rising of our country high grade highway networked, the problem about geology of mountainous area of the highway building is becoming outstanding. so the paper puts forward the integrated control countermeasure to the slope stability, through taking the state specific geological environment of enshi area as the background, regarding the south lidu landslide as the research object, and using the method of finite element analysis
滬蓉國道是國家級東西方向的主幹動脈，是西部大開發的交通要道，隨著我國高等級公路網路化的興起，山區公路建設面臨的環境地質問題也日益突出。本研究論文就是以恩施州特定的地質環境為背景，以南里渡滑坡為具體研究對象，通過運用有限元分析的方法，對山體斜坡穩定性進行分析並提出綜合防治對策。分享友人
