发帖数: 5546 | 1 一般人们更关心弹头结构,弹道,point blank range,MV,Energy,BC,Wind drift啥的,也
是有道理的。因为传统的含铅弹头，从便宜的core-lokt/fusion,到适合lighter
framed deer的SST/Ballistic-Tip,到penetration和expansion都好的Accubond/
Partition等等，连结构和杀伤机理不同的Berger的猎弹也算上，他们的minimum
impact velocity一般就是1800fps. 弹头以大于等于这个速度命中猎物有效区域，会很
可靠地expansion，获得厂家设计弹头时预期的wound channel,energy transfer
blablabla.......总之尽量快速人道地杀死猎物。即使一些MV/BC双低的口径，打一些
重弹头，自己JBM算一下，也会发现1800fps一般出现在400码+，比如这个308win 180gr
Partition, Velocity在大约450码时掉到1800fps：

50-200，16-45反套遮光罩。
K100D在包内显小，但我喜欢有点空的。由于是近三角形的包，包底略显拥挤，但
有很好的pad分隔，并不担忧。
外侧的拉链口袋内做了三个平行的多层pocket，能放手机，存储卡，备用电池，滤镜
等。
Sling背带肩膀及后背部分比较厚实，分担压力。腰带可藏于包背内，可惜的是可能
为了便于Sling，腰带设计仅为单层细带子，仅起到使背包贴合后背的作用。我觉得
重的背包应该有腰带来分担压力，由肩带来保证贴背。可能今天我同时背了电脑包，
所以肩膀还有点吃力。包两侧有宽带，可以挂Accessory Case。
网上没找到Velocity 8x的详图，今天实地看了，才知道V 8x的顶盖是由拉链开合，
并且拉链开口朝内，方便把包转于胸前放取gears，同时也有一定安全性。这点与V8
朝外的塑料扣锁不同。顶盖边缘覆于包外，能起到一定防水渗入的作用。另外顶盖内
上层还有一个拉链包，也可存放点镜头盖，存储卡什么的。
决定选择V8x的原因之一是感觉做工 |

“斥力子理论”对物理学的影响1
庄一龙
近年来，由中国学者创立的“斥力子理论”，经过中国科学院《科技促进发展》《
科技成果管理与研究》、《科技中国》、《中国科技财富》、《中国科技成果》等主流
科技杂志报导后，引起了学术界广泛重视。那么，这一理论究竟有那些观点震动了学术
界，值得人们如此关注呢？
“斥力子理论” 是一种新物质作用理论，实际上也是一种物理哲学理论。它的代
表性文章是《论“斥力子”的存在及其意义》，另外还包括《相对性效应和牛顿定律的
本质》、《物理学中精细结构常数的理论推导与解释》等几十篇论文。同牛顿的苹果从
树上掉下来的万有引力理论相对应，这是一个可称作“苹果如何转移到树上去的‘万有
斥力’理论”。该理论认为，地面的物体一旦动起来，不管方向如何，都具有一种挣脱
地球引力的能力，就好象物体吸收了一种对抗万有引力的物质那样。“斥力子理论”把
普朗克能量子看作是一种对抗引力的实物粒子，称它为“斥力子”，并认为物体运动状
态的改变就是由于吸收或释放斥力子造成的。
在思维方法上，它有两个根本突破：其一,是把抽象的能量概念实物化，使能量有

发帖数: 119 | 35 有可能是velocity saturation effect.因为你的bias voltage比较高，那些channel短
的可能有carrier velocity saturation,导致实际的Id降低，等效于Vt增加；channel
长的（比如10um)没有velocity saturation,这时Id与W/L成比例。这也解释为什么L很
大时，"Vt"就稳定下来，不再降低。你的这些channel长度和bias可能导致一部分L小的
器件受velocity saturation影响，一部分L大的器件不受velocity saturation影响。L
越小，由velocity saturation 导致的Id的降低越大。
你可以试试设比较低的Vgs 和 Vdsat，在很低电压的情况下，velocity saturation 也
许不会发生，这时Id会按W/L成比例变化。
其它可能的影响因素有：contact resistance (or series resistance) 和effective
