都打到driving range尽头的barrier net上。我好奇的问他最远打到多远，他微笑这说
大约可以300+。说完便演示了一个。球actually飞过了约30尺高的barrier net。 关键

发帖数: 4534 | 3 为啥担心5.56的穿透力，小口径速度快，弹体破裂的早，对家具和墙的穿深比手枪霰弹
还小呢。
要嫌对intermediate barrier穿深不够，还有barrier blind弹药。
然后为啥AR比不过专用的猎枪？ chuck hawk写过一篇打猎精度的文章，200码取中小型
猎物, 2 moa的水平足以，何况像样点的AR都sub moa了。
AR的结构也容易保持精度，没有软的木头/composite枪身和glass bedding, 不怕碰撞
而丢失精度， 也不怕泡了水木头发顶枪管，装个快拆镜架和备用铁瞄，就算镜子摔坏
了也不影响枪的使用。 这些在野外都是比较常见的问题吧？
难道AR不适合打猎是因为颜色是黑的？ |

防晒霜分为物理防晒和化学防晒, 物理防晒就是摸到脸上的是一层物理barrier, 主要

突然好了呢？有没有数据做依据呢？其实除了他成绩突然好了之外，没有数据说他体力
好。成绩好了是因为他本来技术就在那里，一个心理因素，一个是饮食引起的过敏因素
，而找到所谓过敏因素其实很大程度也在心理上给小德以暗示，就是他从前总差那么一

变好就是doping相关，我就不那么认为。纳豆伤退是因为吃药怕查出了，小德一直在打
是因为吃药体力变好，没查出来是因为吃的要太高级了，还没有上禁药list。这样的话

具体看你草坪的现状和土壤结构和成分。core aeration的目的是减轻soil compaction

理论上说，如果你的第一次fertilizer里面有pre-emergent除草剂的话(e.g. Scott

如果不做core aeration，你可以用液体的soil conditioner,(Nitron A-35 or

原因一是，女性在性欲上比男性更加克制自己，被动的而不是主动的。也就是属于在沉

而不是把两者区分对待。
二是，性欲需要有一定的barrier才能被激发，比如某种tension,禁忌，power的悬殊，
陌生等，两个女性之间更容易达到intimacy，从而使激发性欲的barrier消失了，而异

Synchronization and memory coherency (memory barrier). Had vector been

on these two methods. It's enough to declare the relevant vars as volatile.
But pre-1.5 volatile semantics was different, and synchronized was the only

然后在主程序中定义一个函数，用来wait，你那个boost的barrier也在主程序中声明，
通过这个函数来等待。就是说，这个barrier的等待不是分别在两个dll中，而是统一通
