TOPIC: MEAT
Cooking meat
Cooking meat is all about producing the right texture and flavours.
Texture concerns the structure of meat.
Flavours are all about chemistry –the Maillard reaction.
Components of muscle
Water: 75%
Protein: 18%
Fat: ~4-10%, varies among different types of meat
Carbohydrate: just over 1%
Vitamins, minerals, various organic compounds…

朗诵很棒!以这样的朗诵,就是文盲也能欣赏好诗吧。:-)
“What a million filaments”根据下一个stanza,应该指诗人的肉体(body)。至于为
什么以“filaments”来代表肉体,个人可以理会不同。例如漂亮的油画:如果你不欣
赏画的内涵而只是欣赏其外在,那么再美丽的画也不过是一堆filaments的集合。例如
夜晚的光明:如果你不体会光明的伟大,那么光明无非就是电灯里的若干filaments。

那个中文翻译真是悲剧啊。。。所有的翻译都是悲剧。西方似乎很少有专门的“翻译家

碳纤维的故事, 你外行了
http://en.wikipedia.org/wiki/Carbon_fiber
Synthesis
Each carbon filament is made out of long, thin filaments of carbon sometimes
transformed to graphite. A common method of making carbon filaments is the
oxidation and thermal pyrolysis of polyacrylonitrile (PAN), a polymer based
on acrylonitrile used in the creation of synthetic materials. Like all
polymers, polyacrylonitrile molecules are long chains, which are aligned in
the process of drawing continuous filaments. A common method

I bought 16/17/18 hexpoly + 16/17 Multi-filament to try first.
CC bought sample pack to try. I did not want to try too many.
After hybrid 6 sets, I prefer 18 hexpoly. But Multi-filament
broke too often for me (4 broken in a month). Now I am trying
to use hexpoly only. But I did buy a reel of 18 hexpoly + a
reel of 16 Multi-filament. I am thinking to use hybrid only in
double matches. The feel is much better. For regular practice
and singles, I will just use pure hexpoly.

Maybe it depends on the type of strings?
I used to use prince problend, always broke the main. I could see that the
main wore everytime i played (and eventually broke when the string became
too thin).
When I play with Babolat Xcel, the cross string does not wear out. Rather it
got squeezed such that the multi-filament does not stick together. Once the
multi-filament is not together as one string, it breaks quickly.

Hi there,
Sorry for bothering. I have a question about E-beam heating on STM machine.
We currently plan to use E-beam heating at the machine but it seems like the
machine has only radiative heating function. Now we need to modify the
power supply and filament a little bit to realize E-beam heating. The way is
to float the current power supply and bias the filament. Does anyone have
relative experience before? It will be perfect if you also use Omicron's

銀河系中心驚現神秘「絲線」 來源不明
https://youtu.be/p3YcJ6cotcE
銀河系中心出現神秘「絲線」,科學家至今未找到形成原因。
據澳洲科技網站ScienceAlert 12月21日報導,科學家早在2012年發現該結構,近期又
獲得更清晰的觀察圖像,但是仍無法找到解開其成因的答案。
科學家使用美國國立射電天文台(NRAO)的望遠鏡,看到這些「絲線」飄散在銀河系中
心附近,長短不一,並將它們定義為NRF(非熱射電纖維,non-thermal radio

報導說,比如有一條長約2.3光年,與銀河系中心存在著密切的位置關係。在圖像上,
銀河系中心像人的咽喉,這條「絲線」像插入咽喉中的魚骨,十分可怕。
科學家起初認為是磁場力產生的「絲線」結構,但是隨著更多絲線的發現,以及它們的
怪異分布方向,科學家很快拋棄了磁場源的設想。
這些絲線似乎與銀河系中心的超級黑洞有聯繫,因此有人設想它們是由粒子組成,且被
