以上亲水部分,请问那个滤膜会不会吸附蛋白呢?很担心损失样品。
在用透析方法做脂质体的时候,还发现一半蛋白进入不了磷脂形成脂质体,而是溶在缓

Champion spark plug shells (the threaded part) use an extruded steel to
maintain exact tolerances. The extruded shell goes through a cold rolling
process to form the threads. This prevents sharp edges which could cut new
threads into aluminum cylinder heads. Once the shell is formed and threaded,
it is zinc-plated to extend its life and reduce the chances of seizure in
aluminum cylinder heads. Our latest technology combines Tin Tac" and
ULTRASEAL'M coatings... 阅读全帖 |

路透报导,美国商务部22日宣布对中国进口的无缝钢管徵收32%至98%不等的惩罚性关税。商务部在21日已表示正在调查中国挤压铝材 (extruded aluminum products)是否有倾销之嫌,或因为政府补贴及其他补助等因素,造成以不合理的低价出售情形。
美商务部在声明中说,提出立案申请的是美国钢铁工会和铝型材公平贸易委员会。数据显示,2007年至2009年,美国从中国进口的铝型材增长 90%,2009年的进口额约为5亿1400万美元。
但中国商务部立即抨击美国的这项举措,表示「强烈反对滥用贸易救济」,并呼吁华盛顿勿採取伤害全球贸易复甦的保护主义措施。
22日,中国商务部也宣布一项课徵反倾销税的措施,包括对从美国、欧洲、俄罗斯和台湾进口的聚己内醯胺纤维,或称尼龙6切片,课徵最多可达96.5% 的反倾销税。商务部网站22日公告说,即日起进口经营者在进口原产于美国、欧盟、俄罗斯和台湾的进口尼龙6切片时,应依据公告中列明的各公司税率向中国大陆 |

两年前,一名加州的铝业公司的高管聘请飞行员飞越谢拉戈达山脉(Sierra Gorda)脚下
墨西哥城镇圣何塞伊图尔维德(San José Iturbide),对一家位于沙漠深处的工厂进行
航拍。
这组照片包含令人震惊的发现。大约100万吨铝材整齐地摆放在被铁丝网围住的工厂内
。这批货物的价值在20亿美元左右,大约占全球库存总量的6%,足以生产220万辆福特F
-150汽车或770亿个啤酒罐,此事迅速引起了美国铝行业的关注。
如今这批铝材成了中美贸易关系新的矛盾来源。美国铝行业的公司高管们指称,这批神
秘存货是一名中国顶级富商阴谋的一部分,试图藉此操控国际贸易体系。
美国行业组织铝挤压材协会(Aluminum Extruders Council)的主席亨德森(Jeff
Henderson)称,他确信中资铝业巨头中国忠旺控股有限公司(China Zhongwang
Holdings Ltd., 1333.HK, 简称:中国忠旺)试图通过取道墨西哥来掩盖货物的原产地

1)你说的对,z6是泛指c6z6,组里都z6叫惯了。另外,13年的z6确实是全铝车身,但13
viper是10年开始设计的,那时候还只有老z6参考。老z6应该是刚车身,因为z6和
viperspace frame的supplier是同一家。supplier来公司报告的时候,把viper和z6的
frame摆在一起,还有点像。不过新z6的全铝车架才和刚车架的viper重量差不多,说明
viper当时的减重还是有成效的,而且更重要的是还有进一步减重的潜力。至于v8,我
猜viper以后也不会有,没有什么比发动机更体现跑车血统和个性。再说,菲克也不靠
viper挣钱,旗下还有法拉利,玛莎拉蒂呢。在跑车这块,我觉得个性比销售更重要
2)即使全铝车架,也可用镁合金的一体化dash/cowl。全铝车架是extruded sheet
metal,而dash和cowl一体设计只能用die cast,这决定了dash/cowl是螺栓固定到车架
上的子系统而不是不是焊接上的一体化设计。在镁和铝都可以die cast的时候,镁更轻
