我试一下啊：
第一问,第二问你都知道：求导得到-F,令F=0得平衡态；
第三问：怎样才能使质点达到无穷远处；
力F在区间（0,a/b）内力的方向为负,其余都为正,所以粒子只要克服此段力的做功就可以达到无穷远处,否则会作周期运动,
所以E大于力在区间里做的功：dW = F* dx；解得W=b^2/(2a)-b^4/(3a^3)

就是解微分方程,初值都给了
1 ds/dt=6sin2t直接分离变量
ds=3sin2t d(2t)积分得s=-3cos2t+C
t=0,s=0,得C=3,于是s=3-3cos2t
when t=π/2,s=3-3cosπ=6
2.d^2s/dt^2=π^2cosπt 直接积分两次
ds/dt=πsin(πt)+C1
s=-cos(πt)+C1t+C2
when t=0,v=8, => C1=8
when t=0,s=0, => s=-1+C2=0,=>C2=1
so: s=8t+1-cos(πt)
when t=1, s=8+1-cosπ=10

粒子的初始能量是
En=h^2n^2/(8mL^2)
因为势垒是缓慢移动的,所以满足绝热近似条件,因此粒子仍处于该本征态上,所以
F=-dE/dL=h^2n^2/(4mL^3)=2En/L
考虑经典粒子
因为En=mv^2/2
所以v=根号下(2En/m)
p=mv=根号下(2mEn)
粒子与势垒碰撞后以相同的速度反弹回去,所以与一个势垒两次碰撞的间隔是
t=2L/v=2L/(根号下2En/m）
则碰撞频率是
f=1/t=根号下(2En/m)/2L
在一次碰撞中改变的动量是2p,所以单位时间内动量改变量即F是
F=2pf=2根号下(2mEn)*根号下(2En/m)/2L=2En/L
和前面的结果是相同的.

其实只要做粒子的对称点
(-2,1,3)
(2,-1,3)
(2,1,-3)
再算对称点与(2,2,2)的距离即可
当然还有反射两次的
对称点为
(-2,-1,3);(-2,1,-3);(2,-1,-3)
反射三次的
对称点为(-2,-1,-3)
没有反射更多次的了,因为反射与对称点是一一对应的

A.24m B.12m C.32m D.16m E.2.0m Please help! 迷茫的烟雨1年前1: shellylu 共回答了26个问题 | 采纳率92.3%

v=dx/dt=2(6.0)t+3(1)t^2 =12t-3t^2
a=dv/dt=12-6t
Now,the question need you to find out the position of the particle when its acceleration is zero.
Hence,
if a=0,
0=12-6t
t=2s
Then,you need to substitute t=2s into the original equation x = 6.0 t^2 − 1.0 t^3.
x=6.0(2^2)-1.0(2^3) =24-8 =16m
Hence,when the position is 16m,the acceleration will be 0

英语翻译AbstractA three-dimensional particle dynamic analyzer (3 英语翻译 Abstract A three-dimensional particle dynamic analyzer (3D-PDA) was employed to measure the gas-solid two-phase flow in a lab-scale square cyclone separator with downward gas-exit.Several cases of different inlet velocity and particle concentration were studied.The particle used in the test was glass bead of mean diameter 30-40 p,m.Discussion was given on the distribution of flow vector,mean velocity,turbulent intensity and kinetic energy of both gas and particles of different diameter at different position in the separator.It was found that the center of the flow field deviated from the geometric center of the cyclone.The flow fields had the feature of Rankine eddy,i.e.,strongly swirling region in the central part and pseudo-free eddy region of weak swirling intensity near the cyclone wall.Local vortex existed at the corners where the flow changed its direction sharply.When the cyclone wall was heated and the suspension temperature was elevated,the flow field became more uniform than that under room-temperature condition.The local vortexes at the corners were weakened and the swirling intensity became poorer which led to decreased total mean separation efficiency from about 81 % to 76.5%.The right-side wall facing the suspension inlet gave the major contribution to the separation efficiency,where the largest downward velocity was measured.Back-flow (upward velocity) was found around the center of the separator above the gas-exit.The quasi-laminar motion of particles enhanced the turbulent motion at the corners due to particle-particle or particle-wall collision, which led to the local peak value of the turbulent kinetic energy and turbulent intensity.The corner was one of the major regions to cause pressure drop and was found to be beneficial to particle separation mainly because the strong fluctuating flow consumed much of the kinetic energy of both the particle and gas. ⑥2006 Elsevier B.V.All rights reserved.

用一种三维粒子动态测试仪（3D-PDA）来测量实验室规模并带有下出口的方形旋风分离器的固气两相流的流场.试验中针对不同的入口速度和颗粒直径进行了研究.试验中玻璃粒子直径分布在30-40pm.本文主要针对在不同直径下的气固两相的流速,湍流强度和动能分布进行了讨论.研究中发现,流场的中心偏离都发生在气旋的几何中心处,流路区域中发现了朗肯涡流.例：强气旋在中心区域发生气旋墙,区域漩涡流场在角落处改变方向处急剧下降.当旋风分离器壁被加热而且气流温度上升时,流场变得比在室温情况下更加稳定.区域漩涡流场在拐角处被削弱,整体的分离效率也从81%降到了76.5%.右侧壁的入口处提供了最大的分离效率,最大的下落速度也发生在此处.回流（上升速度）在出气口的角落处发生.粒子的准基层运动在转弯处被增强,撞击侧壁,导致了湍流动能和湍流强度的原址峰值.拐角是造成这种压力的主要原因.同时,拐角也是有利于增强粒子分离的一个波动因素,因为气体和粒子大部分的流量都转变成了动能.

A particle travelling in a straight line passes a fixed poin A particle travelling in a straight line passes a fixed point O with a velocity of 8m/s and an acceleration of -2m/s^2.it moves in such a manner that t seconds after passing O its acceleration,f m/s^2,is given by f=a+bt.during the first second after passing O it moves through 9m.calculate the value of a and of b. 一个粒子以8m/s的速度直线经过O点，加速度为-2m/s^2。这样行驶了t秒后它的加速度f m/s^2，关系是f=a+bt。第一秒它行驶了9m.求a和b的值。 答案是a=-2 b=12 zhouchunhui1年前3: 咖啡豆7568 共回答了21个问题 | 采纳率100%

设O点即为出发点,则a0=-2m/s^2.看f的表达式就知道加速度的曲线为一条直线,所以经过t秒后加速度f=a0+bt=a+bt,则a=-2.(令t=0)
f=-2+bt,t点速度即对加速度的积分,且V0=8,求得V=b/2*t^2-2t+8,同理位移S即对速度求积分,也即速度曲线与X坐标轴围成的面积,S=b/6*t^3-t^2+8t,令t=1,则S=b/6-1+8=9,所以b=12.

In order to find out the effect of pH on the particle size and zeta potential, HA/CS-plasmid nanoparticles prepared with CS:HA weight ratios of 4:1, for example, were prepared by changing the pH value of the nanoparticle solution from 5.5 to 8.0 shortly after preparation.

1. 位置函数X(t)描述一件物体沿x轴运动, x = -6t^2 + 4, 其中x的单位是米, t的单位是秒.问:
该物体会在 (A) 甚麼时候; (B) 哪裏瞬时停下?
解:
x = -6t^2 + 4两边对t取微分:
dx/dt = -12t, dx/dt就是速度v
那麼当t = 0的时候物体瞬间静止, 其位置x = -6*0^2 + 4 = 4(米).
2. 如果一个物体的位置由x = -5t^3 + 20t所描述, 其中x的单位是米, t的单位是秒, 问:
(A) 甚麼时候(如果可能的话)物体的:速度为0?
(B) 甚麼时候(如果可能的话)物体的:加速度速度为0?
(C) 甚麼时间段内物体的加速度为负?
(D) 甚麼时间段内物体的加速度为正?
解:
x = -5t^3 + 20t两边对t取两阶微分:
dx/dt = -15t^2 + 20 (dx/dt = 速度v)
d2x/dt2 = -30t (d2x/dt2 = 加速度a)
(A) 令dx/dt = 0, 15t^2 = 20, 即t = 2根号3/3 (秒) 时速度为0
(B) 令d2x/dt2 = 0, -30t = 0, 即t = 0时加速度为0
(C) 令d2x/dt2 < 0, -30t < 0, 即 t < 0时加速度为负
(D) 令d2x/dt2 > 0, -30t > 0, 即 t > 0时加速度为正

Abstract:Discrete fuzzy PSO (D-FPSO) algorithm based on Continues fuzzy PSO is proposed in this paper.According to this new algorithm,charisma is defined to be a fuzzy variable,and more than one particle in each neighborhood is allowed to influence others to a degree that depends on its charisma.Shift-neighborhood and mutation is employed to improve convergence speed and avoid to becoming trapped in the local optima.D-FPSO is evaluated on the TSP problem,comparing performance to other methods based on PSO.© 2009 IEEE.
