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 . 她告诉我前面有障碍物的时候就会有声音反射过来,你要仔细听声音的变化。
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 每一首歌都源自他们对生活的体验,内心深处的回音和情感都在歌中表露无疑。
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 本文在我国独立开发的h / hcs - 017型条带测深仪产品的技术基础上,对有关的多波束测深技术进行了研究。
" 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 新警轮的操作亦更加灵活,新船设有先进的热能深测器、全球定位仪器、测深器、雷达、电子海图及电罗盘。
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 目的探讨严重创伤性脾破裂保脾手术治疗的方法及效果.方法回顾性分析严重创伤性脾破裂31例保脾手术治疗的临床资料, 6例行脾动脉结扎+修补缝合术, 13例行脾动脉结扎+部分切除术, 12例行脾切除+大网膜自体脾组织移植术.全部获得随访,随访时间1 5年.结果本组全部治愈出院,无手术死亡病例.术后均恢复劳动能力,无感染易感性增加, b超检查提示:脾动脉结扎者无脾梗死情况,脾切除+大网膜自体脾组织移植者在移植部位可见脾组织回声波.结论对严重创伤性脾破裂病例,行脾动脉结扎+修补缝合或部分切除术是可行的,即能迅速有效地控制脾破裂出血,又能维持脾脏功能.脾切除+大网膜自体脾组织移植术是全脾切除术后弥补脾功能的有效方法
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 多波束测深系统是一种具有高效的、高测量精度的用于海底地形测绘的设备,它是在回声测深仪的基础上发展起来的,特别适合于大面积的扫海测量工作。
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 在海试数据处理中,将wmt法和相位差法联合使用。 h hcs - 017海试数据的处理结果表明相位差海底检测方法在浅海时可以处理到75的边缘波束,实际上已经实现了水深测量的超宽覆盖。测量精度在仿真时小于60工作范围一般小于0 . 3 ;在该角度工作范围,深海数据也达到了0 . 5 ,实现了高精度测量。
