Considering the limitation of the shock experiment of a drop hammer, a shock simulation experiment platform is used to test the shock characteristics of isolators.

针对落锤冲击试验的不足，提出了减振器冲击特性的模拟台测试方法。

But this year is different, Paimaishi quotations, there are short cold market, everyone carrying around measuring calculators, drop hammer is going to be gathered to offer their own new price, more cautious than in the past.

而今年却不同，拍卖师报价后，总有短时间的冷场，大家拿着计算器左右衡量，到快要落锤时才举牌报出自己的新价，比过去谨慎多了。

The dynamic contact of the drop hammer with the laminate was simulated by geometric contact model provided by ABAQUS/Explicit code.

在冲击动态接触过程的处理上，则采用了ABAQUS中主从面几何接触模型，直接利用冲击物的初始速度条件和几何边界条件，将落锤冲击与复合板的变形和破坏进行联立求解。

Impact loading is applied by drop hammer rig.

在落锤装置上进行了充满水的圆柱壳经受大质量低速轴向撞击作用时屈曲过程的实验研究，记录了经受撞击时冲击力和液体内压的时程曲线。

The experiments include low speed compression, drop hammer and SHPB impact test. Some important phenomena and experimental data are obtained from the experiments. These experiments had rarely been done before, for example, the impact experimental result under higher speed has not been reported in the academic journals.

实验包括低速压缩实验、落锤冲击实验和SHPB冲击实验；通过实验得到了一些重要的实验现象和资料，这些实验有些在国内是首次进行的，尤其是泡沫塑料较高速度的冲击实验，国外的报道也极为少见。

Because of its simplicity and convenience in use, drop hammer test machine is increasingly turned into the situation of important test equipment for studying impact capability of isolator.

落锤试验方法，因装置结构简单，操作方便，现已成为在隔振器冲击性能研究领域中重要的手段。

Compared with the shock experiment of the drop hammer, the experiment method accords with the principle of shock isolation, and hence the shock testing results are better reference parameters for the engineering application.

相比落锤冲击试验而言，本测试方法符合冲击隔离原理，因而测试结果对于工程应用具有更好的参考价值。

I felt a drop on my head.

我感觉到有雨滴落在我的头上。

Have one of them fly over and drop them in my yard. I don't care.

让其中一根羽毛飘过并落在我的院子里，我不管，就要这样。

The playoffs are very difficult, made 60 first-round win over the Jazz, the second round to drop 1 to 3 give the Suns, but even under the three Rocket City.

季后赛也很艰难，首轮战胜了取得60胜的爵士队，第二轮以1比3落于给太阳队，但火箭连下三城。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
