First, the phenomenon of the projectile-retarded mechanism of moving plates is introduced, the conditions of the projectile-retarded mechanism of moving plates is analyzed. By a number of numerical simulations, the residual length and residual velocity of the rod which penetrate the fixed plate is contrasted with those of the moving plate. Under the different velocity of moving plate, the relationship between the effect of the projectile-retarded moving plates with thickness and intersection angle of the projectile-retarded moving plates is achieved, and the most optimal thickness and intersection angle is gotten.

首先介绍了运动板抗弹作用的现象，分析了产生运动板抗弹作用的条件，利用数值计算的方法，对比了长杆侵彻固定靶板和运动靶板后长杆的剩余长度和剩余速度，分析了不同的运动板速度条件下产生运动板作用的条件，得出了运动板抗弹效果与靶板厚度和夹角的关系，得到了产生运动板抗弹作用的最优靶板厚度和夹角。

Sometimes, the value of the printed on a flat brush wheel pressure too seriously, to gauge side must increase resistance paper La poorly in this case, you should set the oblato brush round of adjusting screw meanders by inverse rotation axis until the brush, and then press stop to pre-senile meanders turn 1 ~ 2 go, so that the brush can turn in the rotation on paper with the same ease even better.

有时，负纸版上的扁毛刷轮压得太轻，给侧规处事补充必定的阻辛而变成纸弛不推不到位，在这种环境下，答不兵扁毛刷轮的调度螺丝按逆时钟标的目的不静弹，直至毛刷轴罢手不静弹，然后按顺时钟标的目的不静弹1～2不停，使毛刷轮在纸背上能不静弹自若不离算调度好了。

Shotgun shell, such as buckshot shell and shotshell, is different from general cartridge. It has a plastic wad in which many ball shots are loaded.

霰枪弹不同于一般枪弹，以鹿弹和霰弹为例，它有一个塑料弹托，弹托内一般装有数个球形弹子。

The shell magazine in the feeder aims at how to realize the cannon-shot automatically running. A well designed shell magazine will reduce the difficulty of automatic gun, and it also boost up the feasibility of the gun.

Present the rebounding ratio, and analyse the relationship of degree of slope,rebounding value and stability, point out that rebounding ratio is a important factor of effecting the stability of slope, and discuss the relationship of lumpiness ,rebounding value ,rebounding ratio, JRC ,height of slope and the degree of slope, confirm the influencing degree of all kinds of factors to the degree of slope, and the order is lumpiness,rebounding value,rebounding ratio,JRC and the degree of slope.

提出了回弹比，分析其与坡度、稳定性间的相关关系，指出回弹比是对边坡稳定性影响的一个重要因素。确定了各因素对坡度的影响的重要性依次是块度、回弹值、回弹比、JRC和坡高。

The research results show as follows. As plastic deformation increases, the Young's modulus of material continuously changes. This variation law is able to be described using a piecewise linear function .Hardening model and whether the variation is considered or not make great effet on springback prediction. It is proved that the springback prediction result which adopts the elastic-plastic constitutive model based on INLK hardening model and the variation of Young's modulus is considered, is more close to experimental result. After the sheet metal undergoes multiple bending, the corner radius and bending height also affect springback greatly.But the effect trend is different. At the same time, the reliability of springback research using numerical simulation is proved.

研究结果表明：材料弹性模量随塑性变形的变化是不断变化的，该变化规律可用分段线性函数进行描述；强化模型及考虑弹性模量变化与否对回弹预测有很大的影响，基于INLK强化模型和考虑弹性模量变化的弹塑性本构模型对回弹的预测结果与试验最接近；多次弯曲中圆角半径与弯曲高度对板料变形后的回弹有较大影响，但影响趋势不同；证明了数值模拟方法对回弹研究的可靠性。

In the case of attack by KE Projectiles the interceptors are exploded in front of them, to tilt them downwards so that they strike their targets yawed and therefore with much reduced penetration capability.

在动能弹攻击的情况下，拦截弹在动能弹前面爆炸，并使动能弹向下倾斜，因而动能弹攻击的是一个偏斜的目标，这就大大减小了侵彻威力。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
