When the poisonous pesticide is degraded, it is likely pollute soil and water. If the underground water level is within 6 meters to the ground, the eluviated pesticide may pollute the underground water. Thus we have to be cautious when using pesticide

一切的化合物都具有毒素，当施药隐埋后应考虑到农药对土壤、水体降解过程中，药剂施用毒土形成后的向下淋溶径流降解，当地下水位距地面6米范围内时，向下淋溶径流降解的农药就有可能对地下水造成污染，故所应持极其注重态度对待。

The paper presented a new way for the sideway fine feed of cutting piston ring groove : After cutting the groove bottom,the cutting tool make a sideway fine feed of cutting along the groove width to restore the groove width to correct dimension and the cutting tool life being prolonged.

提出了一种精切活塞环槽时刀具侧向微进给方案：在切槽刀具切到槽底后，再作一个微量的侧向进给运动，对环槽的一侧进行微量切削，使加工后的环槽宽度恢复到理想尺寸，达到延长刀具寿命的目的。

The research results show as follows: if the gas pressure is fixed, the seepage velocity of briquets drops at first and rises later with increasing axial stress, and increases after peak stress.

研究结果表明：恒定瓦斯压力时，在某一围压下，峰前渗流速度随轴向应力先减小后缓慢增大，到达峰值应力后，随轴向应力的减小而增大。

The simulation results shows that when the hydroforming for real axle housing needs two bulge processes and the specific value of the two bulge ratio is about 1, the result is the best one; To obtain an appropriate route of loading force need adjust internal pressure and axial compression force for many times and according to the failure, the size of the two forces which has been mentioned can be rapidly and rationally adjusted; Because of good greasing conditions influencing largely, reducing the friction between tube blank and die inside surface as well as possibly not only makes more materials flow into the bulge area but effectively diminishes the axial compression force; The good or bad characteristics of tube blank material is also one of the decisive factors and when material is selected, we first consider its' formability.

模拟结果表明，当后桥壳需要两次进行胀形，两次胀形比比值约等于1时，胀形结果最好；合适的加载路径要经过多次调试，能根据胀形缺陷对内压力和轴向力的大小进行迅速地合理调整；良好的润滑环境对后桥壳液压胀形的影响巨大，要尽量减小管坯与模腔内壁的摩擦力，不但使更多的材料流入胀形区，而且能有效的降低轴向力的大小；管坯材料性能的好坏也是影响胀形的决定性因素，选材时首先要考虑材料的成形性。

Hotel brokers dragged staggering pace, with a look of exhaustion luggage into the station, one that is open to police to borrow money that is太岁头上动土encountered fraud syndicate, police did not believe the beginning, after the investigation turned out that name of the hotel brokers before working in Hong Kong to Taichung, after work has been unable to find a new job, spend money and helpless body, and want to go home but no money to ride, forced only to adults for help we the Boli Shi, raising more than 500 police vehicles block the money to the hotel brokers , good people to do in the end, and also patrol car with the hotel brokers to the station to ride bow deeply to the police adult Thank you kindly, hotel broker promised to find a job after returning Kaohsiung made money, some Taichung peace will return to the police station to thank the police who help him.

酒店经纪拖著蹒跚的步伐，带著行李一脸疲惫走进派出所，一开口就是要向员警借钱以为是太岁头上动土，遇到了诈骗集团，员警一开始还不相信，事后调查原来这名酒店经纪日前到台中港打工，工作结束后一直找不到新的工作，无奈身上的钱又花光了，想回家却没钱坐车，不得已只好向咱们的波丽士大人求助了，员警集资五百多块的车钱给酒店经纪，好人做到底，同时还用巡逻车载酒店经纪到车站搭车深深一鞠躬谢谢好心的警察大人，酒店经纪允诺回高雄后找到工作赚了钱，一定会回台中安宁派出所来谢谢帮助他的员警们。

The provisions of the zone system, there are still a problem: If you travel around the world from west to east, across every time zone, we will forward your table set aside for an hour, so that when you are 24 time zones across the back place, you just forward of the table also allocated 24 hours, which is the same the second day of a part-time; the contrary, when you travel around the world from east to west after lap, your table is indicative of the same day before the part-time .

规定了区时系统，还存在一个问题：假如你由西向东周游世界，每跨越一个时区，就会把你的表向前拨一个小时，这样当你跨越24个时区回到原地后，你的表也刚好向前拨了24小时，也就是第二天的同一钟点了；相反，当你由东向西周游世界一圈后，你的表指示的就是前一天的同一钟点。

The simulations for the obtaining result in Ku wave band show that the size of the pricipal target affects greatly both the forward sactter and the backward scatter. The influence of the targets around shows definite periodicity. The second scatter field minishes with the increase of distance between two targets. The more near the forward area the rounding target is, the bigger its affect is.

结果表明：本目标的尺寸对前向散射和后向散射均有较大的影响，周围目标的影响呈现出一定的周期性，二次散射随着目标间距的增大而减小，周围目标离前向散射方向越近，对前向散射的影响也越大。

Experiments show that it is realizable to use the two-component OEHF-LDA in backward scattering mode.

本文对二维OEHF—LDA用于后向接收的可行性进行了探讨和试验并获得成功，这是采用小功率激光器实现后向散射接收二维LDA测量的首次尝试。
