I've been to bat 35 times and have only three strikeouts. That tells me that I am hitting the ball, but everything I hit seems to be an out. Out, out, out, and I don't know why. I can't do anything about it. All I can do is keep trying to hit the ball hard every time I go to bat.

在我 35 次的打击当中只有三次三振，这说明我能打到球，但是都跑到别人的手套里去，出局再出局，我不知道为什麼，我无法做什麼改变，我能做的是当我在站在打击区时，继续努力击中球。

Taking a general view of the paper, major innovative ideas and returns are as follows: The main innovative ideas are as follows: 1. The paper put forward the new idea that combine water-saving drilling with rotary percussion drilling creatively according to the present situation of water resource lack seriously and the background of implementation of state geological survey strategy. 2. The working principle of new designed system of water-saving hydraulic percussion device completely different from traditional hydraulic percussion device, the system can carry out rotary percussion drilling on the condition that no surface water be consumed, and achieve the purposes that saving surface water, cutting cost and improving drilling efficiency. 3. The design conception of steel ball percussion device is very novel, the percussion device is durable, with a simple structure, at the same time drilling efficiency would be improved highly and drilling cost would be reduced greatly when drill with the steel ball percussion device.

综观全文，论文的主要创新点及研究成果如下：主要创新点： 1、结合我国许多地区水资源严重短缺的现状以及国家实施地质大调查战略的背景，创造性地提出了&节水钻探&和&回转冲击钻进&结合起来的新思维； 2、设计出的节水型液动冲击器系统，其工作原理跳出了传统液动冲击器要消耗大量地表水的原理模式，在基本不消耗地表水的情况下便能实现回转冲击钻进，达到节约地表水、降低成本、提高钻探效率的目的； 3、设计的球体冲击器构思新颖，克服了同类产品冲击功传递效率低的弊端、且结构简单、经久耐用，可大幅度提高钻探效率、降低钻探成本。

While a ball mill is working, balls in the mill are lifted, and then are thrown away with a certain velocity to collide raw material. But at the same time, balls and underboarding are also got collision which may make balls and underboarding fracture. Considering the tough lubrication condition and dust and prills have easy access to meshing zone of gears, the heavy abrasion on gear surface often appears in the upstage gear of open-gear transmission of ball mill.

当球磨机正常运转时，磨球被提升到一定高度后抛落，以一定的速度对物料产生冲击而粉碎物料，同时也对磨球和衬板自身产生冲击，这可能造成磨球和衬板的破球磨机的末级开式齿轮传动，由于润滑条件差，粉尘、金属颗粒容易进入啮合区，齿面常常出现严重磨损，导致齿廓形状发生变化，最后因齿厚磨损过多而折断。

Once you've marked the positions of the ball, VideoGraph generates a data table that gives the ball's coordinates and velocity as a function of time.

一旦您标记的立场球， videograph生成一个数据表，让球的坐标和速度作为一个时间的函数。
