真的是这样。"soft is harder" 我也发现了，好几次我就是打深上旋到中路，来回几
下，他就先失误了。或者轻轻打角度，反倒很有用。这就是为什么我说我也回moonball
给他的原因。
其实我有时也知道他喜欢什么球不喜什么球，好多good shot给他救回后，就是钻上了
牛角尖，非要让自己发力打死他。心里总在较劲要打更快，更大角度一定要让他接不回
来，结果自己先失误了。
在回答你的问题 "How's your serves? How is your chip or slice? How is your
volley? how is his volley?"
My 1st serve:
40% of match time, I hit with angles (normally backhand) and speed around
70MPH with around 30-40% success;
10% of match time, I hit without angles and with speed around 80MPH around

那我得live up to my rep. =P
第一分最后那个miss, 就是我所说的， 如果你能把那球看做 "it's just a shot,
play for the next shot", 你可能会选择drive dtl and go to the net. 我认为那球
其实该打dtl. 对手被你前一球打开了， 很被动， 他急于回防， 他反手不如正手，
虽说dtl离他人近，但most likely it will be behind him. 而且也不用打太猛。 感
觉你把这球看成easy shot, finish shot, attack shot了， 把他往死里抽， 因为你
这心态， 你的整个人tight了--》脚步没调整--》spacing 不好的猛抽---》 悲剧
第二分。。。打得不错，欢乐结束 =）
第三分最后那球我觉得你如果要打他正手， 这球你该step in (close stance), drive

发帖数: 6757 | 5 我觉得还是准备， 普遍WSN的问题。
正手， 我觉得你的引拍还是主要靠右手伸出去， 最好是多用肩和左手。 当你转肩（
胸对着side fence）时， 你的拍子基本没动，还在胸前或偏左手边一点。当你开始转
肩时，左手该送/推拍向后/向右 （这时右手基本还是空握，保持放松）， 送过胸后右
肩顺势后移， 右肘也是顺势向后拉开些。 但右肘基本还是有些弯的 (你的看上去有些
刻意的伸直，lose time, easy to get tight).
joker fh (start from 1min mark)
http://www.youtube.com/watch?v=XenZjoDCU8Y
-->注意他一转肩，拍子已经在胸的右边了， 转肩和左手送拍是同时进行 （make time)
反手，可以说是同样问题. 肩转的同时，左手就该拉拍了， 这样你才有时间把拍拉的
和地面基本垂直 （help with racquet drop as you swing)。你可以试着尽量把左肘
抬高些。 老费基本是引拍左肘抬的最不高的一个了 ，但他抬得还是比你高。 :P

You can try to find another player with his chin this close to shoulder in
the same side view angle, and the head tilt. Perhaps baby Federer is like,
Nadal is somewhere close.
Here is the comparison at about same angle between Federer (0:09, 0:14) and
Djokovic's(0:04, 0:25 etc), you can calculate the stance and average turning

发帖数: 6757 | 7 终于静下心看了lz的和其他大侠们的意见。我非常认同 WatermanCT 的意见, 当我看时
，这也是我想说的意见之一(he beat me to it). it's always easier to move
forward to hit a ball than falling back.
stroke 而言， 不容易说， 你有些球的stroke 有问题是因为你站太前， 对手球深，
你一时来不及而造成的， 特别是反手。 有几个正手打得很不错。 准备最好能够再早
些。 要看stroke的话， 这个角度不是最佳。。。 真要analysis 动作的话, 你换个
camera 角度， 让人喂球。 不过lz的stroke 不是什么特别大的问题。
cross court 问题， 用 semi-western, western grip, 打cross court 都有些
tricky. 看了你几个cc, especially on the run, 一个普遍的问题(including
myself),是stance. 你基本是右脚在左脚后方relative to the baseline.... 阅读全帖 |

Basically, what is that when I volleyed the ball very close to the net and
sideline in a very small angle, the opponent would usually chip it back
cross the net (angle to angle). Occasionally, he may just pops it up and
hoping to be over your head. This time I was right there waving my racquet

发帖数: 6757 | 9 Between deep middle or deep angle, that's more of game plan. Which is more
aggressive or more risky really has to do with your positioning and how that
shot came about (changing of angle ) frankly i think the way to approach
this is have a game plan, your movement should evolve around that. You
choice of angle or middle should let your subconscious decide.

进攻时你要什么球也可以喊：5/4/3/2/1/slides/cross......
后排的有A/B/C/D/pipe

会有人盯住setter二次球，对方扣球出界时，你要是手摸到了要喊touch，这样崩出去

发帖数: 46 | 40 求问器材版各位有经验之士，思睿 sirui W-1204 carbon三脚架是不是性价比最高的三
脚架了？
我真的不是托，就想做点功课研究一下，加上球头预算在500以内，需要便携总重量在1
.5公斤以内，广角16-35和100-400这样的长焦都能使用的一个三脚架，需要中轴能够取
下来，最好一个脚能够取下来变成 monopod，然后要 carbon，要旋钮式固定脚架，可
以换钢钉用到冰面上。看了一圈，貌似这个 w-1204比较满足我的条件，和大家交流，
也希望大家多提建议：
Waterproof leg design protects your tripod from water damage.
Ergonomic Leg Angle Locks for fast adjustment - even with wet or gloved
hands.
Lightweight 10 layer 100% Carbon Fiber for added strength, increased load
capacity and vibration reduction.

发帖数: 1524 | 41 Put projection of D on AC with right angle
Put projection of F on AB with right angle
Put projection of E on BC with right angle
you got two groups of right triangles,totally 6
you will find it soon AB=AC=BC with those right triangles |

http://splitsider.com/2011/11/talking-to-molly-mcnearney-the-co
One of the most hot button issues in comedy right now is the lack of women
writing for late night. Molly McNearney is the only woman who currently
writes for Jimmy Kimmel Live, but she is also the co-head writer. Molly
chatted with me about how she got her start in comedy, her favorite bits
that she’s contributed to the show and what it’s like being a woman behind

发帖数: 787 | 43 I am certainly no math whiz, but "the angle with regard to XXX" does not
sound very good.
you can say one of the two things below:
1. X and Y form a 45 degree angle.
2. The angle between X and Y is 45 degree.

发帖数: 1968 | 45 以上是我从科普角度发文的，。呵呵，其实我是做quasicrystal的，虽然不是做不粘锅
的。
严格来说，浸润或不浸润对应着讲表面能的大或小，contact angle的小或大。只要是
纳米结构，在几何上面，就应该会让小于90度的contact angle变更小，大于90度的
contact angle变更大，所以对于水不浸润的材料，纳米结构能加强其的对水不浸润性
，这是显然和不奇怪的。但是一般hydrophobic不浸润水的材料，都是浸润油的，怎样
做到2者都不粘，就需要很特殊的结构来组合亲水和亲油的材料。而某些Quasicrystal
合金到底是怎么做到的，具体结构如何，我还没有读过一篇清楚的专业论文，也许是专
利和商业机密。只是，这样的合金锅确实早就有了，而且很贵。不过学物理的人还是有
点好奇，细节的结构到底是怎样的。 |

发帖数: 469 | 46 But if you decide to buy 50' TV, why would you care plasma cannot be
small, etc? I guess cost/picture quality makes more sense, and this is
exactly where plasma is better.
One additional advantage of plasma: the view angle is way better than LCD,
even though both claim around 178. In reality, LCD TV's picture quality
drops miserably for any angle other than 90, while plasma has uniform
picture in any angle. |

我在这儿买过不少。有很多种SATA cable. right angle, left angle,带latch.
flexible的，各种长度，质量还不错，价格也还可以。monoprice没那么多选择
90度转角头主板和硬盘上都可以用，不过一般用在硬盘上。我的lian li机箱用left
angle的接在硬盘上走线比较方便，干净。 |

发帖数: 736 | 48 谢谢Soar答复。刚做了功课：
TN (Twisted Nematic，扭曲向列) ，属于早期技术most
common technology and also the oldest。优势是response fast，low price。
最大的缺点是the color shifts at wider viewing angles。
In-Plane switching (IPS，平面转换），成本高，最大优势是noticeably better
color reproduction as well as much better viewing angles...keep colors
constant, even in sharp angles。 |
