发帖数: 908 | 1 HANDGUN AMMUNITION:
SELF DEFENSE
Ammunition manufactured in the United States is among the finest in the
world. For intended defensive uses, the gun owner will not go wrong in
selecting ammunition produced by the most widely recognized manufacturers.
These include CCI/Speer, Cor-Bon, Federal, Remington, and Winchester.
Allow no margin for error in protecting one's life. Avoid potentially
unreliable ammunition that is hand loaded, re-loaded, or of dubious quality
foreign manufacture when ch... 阅读全帖 |

发帖数: 578 | 2 US made AK74 receiver sucks, don't buy it unless you want to call the
manufacture for repair. My IO AK74 receiver and rivets started to deform
after only shooting less than 60 rounds. I called IO and they sort of
admitted that and told me that's the reason why they stopped making AK74. |

blank”是从保加利亚来的。还有枪管也是保加利亚的。
"Each SAM7R receiver is milled from a hot-die hammer forged receiver blank
by the Arsenal Co. of Bulgaria. Other milled-receiver AKs are machined from
bar stock, but Arsenal’s hot-die hammer forging produces stronger and finer
-grained steel. Internal voids and cooling deformations are eliminated by
the 5-ton hammer forging process." |

发帖数: 2243 | 11 my current blade is Hurricane Hao, old version. There are several reasons I
choose it:
1. Best RPB blade. My back hand (mainly RPB) has been improved a lot after

2. Excellent deformation when you hit a ball
3. Nice loop blade. The loop given by this balde is more stable and spnning
than other blades I tried.
4. Nice and solid hand feeling.
5. Comfortable to hold. My hand is not large, this blade is just fine for
my hand.
Only one defect: not that good in short control. |

发帖数: 1389 | 14 it can't be real. the surface of clay court is much harder than tennis ball.
and tennis ball is too light processing less energy even it travels at high
speed. therefore, before the tennis ball can dent the ground, itself deforms
. in addition, the landing angle is so sharp that ball will roll upon the
contact and the pressure built up inside will be strong enough to lift thing
as light as a tennis ball back into the air. |

发帖数: 30533 | 15 Ok, found the specifics:
It's Prince Magnesium Pro 110. 12.1 oz. Claimed 110 head size, actually
about 103. Head light (not sure how many points). Grip size 4 1/2.
It was made in the same era as the POG, but one level cheaper.
Wood
Aluminum
Magnesium
Graphite
Boron
It feels almost as elbow friendly as the POG. However, the frame tends
to deform over the years, since Magnesium is not as strong as graphite.
Other than that, it should feel quite like the POG.
So for $2 I got:

发帖数: 7271 | 16 Even for table tennis, you should be able to generate more spin when you use
softer sponge or blade because it allows the ball to stay longer on the
racket.
Tennis is the same. Given that everything else is the same, dense string and
smaller head size give you less deformation and shorter contact time, hence
less spin. Of course, different string property (e.g., softer or gauge or
so on) will affect how much spin too.

Wilson Graphite Force 85: actual head size around 88, strung

than Sting, probably 55-60?
Prince Magnesium Pro 110: actual head size around 103,
strung weight 12.1oz, very HL (more than 5). Stiffness unknown,
probably 50-55? (too flexible, the head even deforms)
Head LM Radical 98: actual head size around 95, strung weight
11.2oz, 4pt HL (feels less HL than that) |

发帖数: 10373 | 20 Before workout, the muscle is stiff, cool and fragile. Dynamic stretch helps
the blood flowing and makes the muscle warmup. Static stretch will reduce
force output so it is really bad to do it before the workout.
After workout, static stretch deforms the muscle tissues, and increases the
tolerance for pain. It is very good for recovery and the next day exercise. |

发帖数: 85 | 22 the amount of deformation of the clay court or hard court would be minimal
with a DROPPED ball (which only has the vertical component), so almost all
of the bounce would be due to the nature of the ball and not of the surface.
But we are dealing with a tennis in the game, so the increased friction of
clay courts help to 'redirect' the forward momentum of the ball upward
causing a higher bounce. |

In case you friend still wants to argue about the Hawkeye projection,
you can ask him why the projection has never been exactly circle, which
it should be the very moment it starts to touch the ground. In fact,
Hawkeye has taken into account the angle of the ball approaching the

人很有限，到2020年，全球讲英语或学英语的估计20亿人中，母语为英语者将只占15%
。事实上，现在的英语交谈，已有一大半是使用洋泾滨。
中国估计有3亿人(相当美国人口总数)会读写英文，可是缺少口语练习机会，正宗英文
老师又少，更助长洋泾滨英文发展。
这种情况可能导致愈来愈多口语英语，变得愈来愈像中国话。中国人和其他亚洲人的英
语发音，已有各种微妙和显著不同。
在中文语法影响下，英语文法特有的一些附加字词(例如在问句前面加do或did)可能消
