According to earth - bound and space - bound observations , the black drop is confirmed to be a mere optical illusion caused by the earth s atmospheric turbulence and insufficient resolution of small telescopes 根据世界各地及卫星的观测，黑滴现象是由于地球大气层的扰动及部分望远镜的解像力不足而产生的光学假象，并非由金星的大气层造成。
Examining the simulation results , the deformation of sheet metal would affect the magnitude of electromagnetic force , and the corners of sheet metal had worse formability because of the insufficient electromagnetic force and flash 由模拟结果可知，成形过程工件的变形会明显的影响电磁力的大小；同时，无预成形板材角落之成形性受到电磁力不足与馀料太多的影响，成形较其他部位差。

Problems in using screw - crane in fields and water resources engineering were analysed with examples of engineering project . based on this , a method was presented . by using double - hook screw - crane and connecting two screw - cranes by an intermediate bearing and a gear coupling , the problem of inefficiency in door - closing was solved . the double - hook screw - crane could work synchronously 以具体工程为例，在分析了螺杆启闭机在农田水利工程中应用时存在的问题及原因的基础上，提出采用双吊点螺杆启闭机，用中间轴与齿轮联轴器把2台螺杆启闭机连接起来的方法，成功地解决了单吊点启闭机闭门力不足的问题，实现了双吊点螺杆启闭机工作时的同步
At last , the paper evaluates modernization of towns in county administrative areas by quantitative way . it points out many problems at present in the span of scale alteration . for example , the ability of convergence is limit , land - use per - person exceeds normal standard , a lot of towns are lack of fund , the infrastructure lags behind 最后，以全省222个重点中心镇为研究对象，对县域城镇的现代化水平进行定量化评估，指出县域城镇规模变动过程中所面临的问题，如人口吸纳力不足、人均用地严重超标、城建资金匮乏、基础设施滞后等，并提出了进行制度创新、增强城镇集聚能力等对策和建议。
Where the shoe pinches of the repair success is all right combination of young and old concrete . presently , most of the researches inside and outside country made the two into one to against force through felt . in practice , however , it ca n ' t obtain ideal bond capacity only depend on adherence . thus , this paper bring forward a young method to make up the lack of felt capacity - use mechanical joint element to link young and old concrete 新老混凝土之间的良好结合是混凝土修补成功的关键所在，目前国内外的研究中绝大部分是通过二者的粘结作用使其结合成为整体共同受力。而实际工程中仅仅依靠粘结力往往达不到理想的结合程度。因此，本文研究的是加强新老混凝土结合，弥补粘结力不足的一种新方法，即采用机械连接件将新老混凝土结合在一起的方法。
The qualifications punishment though has the malpractice of penalty to be surplus , deter ’ s power to be insufficient and so on , but because it has unique function in the special prevention aspect as well as complied with the penalty ’ s leisurely , the non - inprisonment worldwide development tendency , the qualifications punishment no matter all has the very high research value in the fundamental research domain and in judicial practice 资格刑虽然存在刑罚过剩、威慑力不足等缺陷,但由于其在特殊防卫方面的独特作用以及顺应刑罚轻缓化、非监禁化的世界发展趋势,资格刑不仅在理论研究领域还是在司法实践中都具有很高的研究价值。
As the reinforced concrete highway bridge built in 1960s ? 70s in china , the load - bearing capacity of xingtan bridge is insufficient clue to the increasing traffic and the overloading of trailers and container vehicles . on the other hand , the bridge was wore out and damaged . so , a perfect retrofit scheme needs to be carried out in order to meet both safe and economical demands 同我国六七十年代建造的钢筋砼公路桥梁一样，普遍存在因交通量增大、拖挂运输车、集装箱车辆超载运输等原因造成桥梁承载力不足。加之桥梁老化、破损，迫切需要对旧桥进行技术改造，采用加固补强使其达到既能安全行驶，又节省投资。
