In this paper,the effect of pre-stress on peen-forming is studied by experiments,the results show that pre-stress can change the relationship between pre-deformation and pre-stress shot peen deformation,and that 0.05%～0.1%pre-strain is comparetively suitable to improve the spanwise rectilinearity of shot peen-forming configuration surface.

文摘：对预应力喷丸成形进行了试验研究，指出预应力可以改变其对应的预变形与预应力喷丸变形之间的大小关系，在以改善喷丸型面纵向直线度为主要目的的预应力喷丸成形中，预应变取值0.5/1000～1/1000较为适宜。

The investigation has declared that the fuel injection with BQ fuel pump had higher injection pressure, bigger fuel supply rate and shouter fuel supply duration, which would cause the fuel injection quantity and the fule-air mixture to increase during ignition delay period, the pre-mixed combustion to become acutely, and finally result in increased power levels of noise.

研究表明，装配BQ喷油泵，喷油系统的喷油压力较高，供油速率较大和供油持续时间缩短，使得滞燃期的喷油量增加，滞燃期内形成的可燃混合较多，预混燃烧剧烈，导致整机噪声声功率级增加。

The calculation of melt shear rate , jet stretch ratio and spinneret back pressure was analyzed and discussed, which decided the diameter and L/D ratio of spinneret.

分析了涤纶长丝生产中喷丝板选用的相关理论，对熔体的切变速率、喷丝头拉伸比、喷丝板背压的计算方法进行分析讨论，认为 3个参数可作为选择喷丝板微孔直径和长径比的依据，并举实例进行了验

In the experiment, the TiO2 nanoporous films were made dy using multiple sprinkling technique in the home-made sprinkling box instead of the doctor blade method. The multiple sprinkling technique can quickly produce the TiO2 film and easily control its thickness, i.e. transmittance. The multiple sprinkling technique made TiO2 films receive the result that the higher heating temperature and the longer heating duration, the better photoelectric conversion efficiency . The experimental data show that the sprinkling technique is better than the doctor blade and the DSSC integrated with the photoelectrode ca.

实验中自行制作喷雾箱，以多次喷雾的方式制作TiO2多孔膜，取代传统的刮刀涂布法，达到快速制作及容易控制膜厚或膜之透光率的目的，当藉由喷雾法所制作的奈米TiO2多孔膜烧结温度越高时，其光电转换效率也越好，烧结时间越长，DSSC光电转换效率越佳，整体之效果，喷雾涂布法有较优於刮刀涂布法的效果。

In order to solve the problems, the experiments were carried out to study the effects of MET on the physiological and agronomical characteristics and yield of peanut. We hoped to find out the best PP333 density treatment and the best application period.

本试验应用多效唑对花生进行处理，一方面研究喷施不同浓度多效唑对花生生理性状、农艺性状、产量性状的影响作用，旨在寻找适宜的喷施浓度；另一方面比较分析不同时期喷施的效果，确定多效唑喷施的最佳时期。

Other cause can be vibrations of the print head letting small air bobbles inside the print head preventing the ink head of firing one ore more nozzles, also change of cartridges can let a little bit of air inside the ink system, in case of missing nozzles it will look like white line within the print, then push the pump bottom for a few seconds, please have a JetMaster tissue in front of the head when using the pump, otherwise you are facing ink all over your machine, the ink can spray more than one meter out of the print head using this function, so please use it carefully.

喷印头的振动释放的小茸球在喷印头中阻塞喷头的一个或多个喷嘴的射击，同时和的变化会使一点空气进入油墨系统，避免喷嘴的缺失。然而当喷嘴丢失时，喷印看起来像白线，这时推动操作泵底部数秒。请在顶端前有Jet Master棉纸时，使用操作泵，否则油墨会溅到机器上，可溅出喷印头1米多。因此，请谨慎使用。

But for the second type of peened specimens, the moderate-peening regime is stricter and the over-peening stage comes earlier than that for the first type of peened specimens.

第Ⅱ类喷丸试样较第Ⅰ类喷丸试样的适度喷丸规范要严格，而且其过喷丸情况也易于出现。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
