The results from the processing of h / hcs - 017 multibeam echo sounder data has shown that this combination method can detect a wide horizontal range up to 75 angle to the vertical and obatain the so called ultra - wide coverage detection the precision of measurements has been given under 0 . 3 % generally when surveying angle is under 60 ? angle in simulation data , while under 0 . 5 % for deep sea detection in the same angle range therefore this method accomplishes high precision measurements 在海試數據處理中,將wmt法和相位差法聯合使用。 h hcs - 017海試數據的處理結果表明相位差海底檢測方法在淺海時可以處理到75的邊緣波束,實際上已經實現了水深測量的超寬覆蓋。測量精度在仿真時小于60工作范圍一般小于0 . 3 ;在該角度工作范圍,深海數據也達到了0 . 5 ,實現了高精度測量。

Multibeam echo sounder system is a kind of sea bed surveying instruments which can work efficiently and accurately its development originally bases on single beam echo sounder this kind of system is very suitable for massive sea floor surveying the technique behind multibeam echo sounder system has achieved its maturity with time passage 多波束測深系統是一種具有高效的、高測量精度的用于海底地形測繪的設備,它是在回聲測深儀的基礎上發展起來的,特別適合于大面積的掃海測量工作。

Objective : to investigate the method and effect of reserved splenectomy on severe traumatic spleen rupture . methods : 31 cases of severe traumatic spleen rupture were retrospectively analyzed . 6 cases were treated by ligating spleen artery with splenorrhaphy , 13 cases by ligating spleen artery with partial splenectomy , 12 cases by splenectomy with autologals spleen transplantation in epiploon , follow - up of all patients was completed from 1 year to 5years . results : all patients recovered . no patients died from surgical operation . patients could work after operation and the susceptibility to disease didn ' t increase . b supersonic inspection showed that : splenic infarction didn ' t exist in patients treated with binding spleen artery , echo sound was heard from transplanted spleen in patients treated with splenectomy and autologous speen transplantation in epiplom . conclusions : it is feasible for patients with severe traumatic spleen rupture to treat by ligating spleen artery with autologous spleen transplantaion in epiploon , which can efficiently control hemorrhage and maintain the function of spleen . splenectomy with autologous spleen transplatation in epiploon is an efficient method to make up furthur function of spleen after splenectomy 目的探討嚴重創傷性脾破裂保脾手術治療的方法及效果.方法回顧性分析嚴重創傷性脾破裂31例保脾手術治療的臨床資料, 6例行脾動脈結扎+修補縫合術, 13例行脾動脈結扎+部分切除術, 12例行脾切除+大網膜自體脾組織移植術.全部獲得隨訪,隨訪時間1 5年.結果本組全部治愈出院,無手術死亡病例.術后均恢復勞動能力,無感染易感性增加, b超檢查提示:脾動脈結扎者無脾梗死情況,脾切除+大網膜自體脾組織移植者在移植部位可見脾組織回聲波.結論對嚴重創傷性脾破裂病例,行脾動脈結扎+修補縫合或部分切除術是可行的,即能迅速有效地控制脾破裂出血,又能維持脾臟功能.脾切除+大網膜自體脾組織移植術是全脾切除術后彌補脾功能的有效方法

“ navigating the craft is also made much easier because it is equipped with state - of - the - art thermal imager , global positioning system , echo sounder , radar , electronic chart plotter and gyrocompass 新警輪的操作亦更加靈活,新船設有先進的熱能深測器、全球定位儀器、測深器、雷達、電子海圖及電羅盤。

Based on the instrument of h / hcs - 017 multi - beam echo sounder developed independently by us , this dissertation studied aspects of different kinds of techniques related to multi - beam surveying 本文在我國獨立開發的h / hcs - 017型條帶測深儀產品的技術基礎上,對有關的多波束測深技術進行了研究。

Each of the songs originates from the life experiences of the two and echoes sound and feelings that seem to well up directly from the depths of their hearts 每一首歌都源自他們對生活的體驗,內心深處的回音和情感都在歌中表露無疑。

She told me : “ echoes could be heard when there are obstacles in front of you . you should listen carefully to the variations among the echoed sounds . 她告訴我前面有障礙物的時候就會有聲音反射過來,你要仔細聽聲音的變化。

It is important to eliminate or degrade the effect caused by the beam width of echo sounders and reflect the true seabed 為提高海底地形的測量精度,應消除或減弱波束角效應影響。

He tried it ; but in the darkness the distant echoes sounded so hideously that he tried it no more 他叫了幾聲,可是黑暗中,回聲聽起來十分可怕,他只好停下來,不再叫喊。

In bathymetric survey , the recorded seabed is distorted due to the beam - width of the echo sounder 摘要在海底地形測量中,由于波束角效應導致探測的海底地形存在失真。
