1, 公司概况和产品:
A123 Systems 的网页:http://www.a123systems.com/company
它生产的是Lithium-Phosphate可充电电池,有如下优点:
1 环保,无污染,称为绿色能源:
2 电压高, 一只3.3V, 可大电流冲•放电:(10 到 20C 放电)
3 循环寿命长,2000次左右,一般二次性电池在大电流下是500 – 800 次:
4 最后也是最重要的是:使用安全,不会爆炸燃烧。
2,公司的潜力和优势:

Phosphorus is a key element in all known forms of life. Inorganic phosphorus

molecules such as DNA and RNA where it forms part of the structural
framework of these molecules. Living cells also use phosphate to transport
cellular energy in the form of adenosine triphosphate (ATP). Nearly every

养水真是一个需要耐心的活。 nitrite 这一个星期一直徘徊在0.25-0.5ppm左右。 直
到昨天才降到0ppm. 准备再养两天再换水, 让菌落稳定下来。现在水质的参数是:
11/13/2016
pH: 7.8-8.0
ammonia: ~0 ppm
nitrite: ~0 ppm
nitrate: 40ppm
calcium: 400ppm
phosphate: 0ppm
KH:6-7
temperature: 79F
salinity: 1.024
add ammonia every day to rise its concentration to 1-2 ppm.
KH值有点低, 应该在8-12之间, 不知道是不是因为还在cycle还是加了盖子的原因,
准备看看到时候换水能不能恢复。
由于用的是dry rock和蒸馏水, 水里硅和磷含量几乎没有, 估计爆褐藻的几率应该很

If you take a pY peptide and try this, you will not be able to
see the loss of phosphate group easily. The phosphate group on
the Tyr residue is really stable. However, this phenomenon is
true for pT and pS peptides because they are much less stable.

二、农业部查询转基因大豆安全证书
农业部在2011年第一次答复我们最初查询要求时说:批准美国孟山都公司转基因大

Mercedes did not. BH is stuck. BYD does not have the nano technology to
make EV grade iron-phosphate batteries.
No companies in the world has that capability to make it on industrial scale
.
Understand that?
BYD won by using manual labor to replace automation, the exact reverse of
progress in modern industrial production.
You think that has future?
Again, EV grade need tight uniformity at nano evel for the particles. No
one can do it yet, at industrial scale. Not even the Germans.
