要求：
1. 安全、操作方便；
2. 空间要大，既有恒温培养箱；另外还要有足够大的存储和操作台的空间。
3. 性价比高；
以前实验室都是用 Coylab 的；但感觉有时候会漏气。
不知道大家有没有别的可以推荐的？BACTRON 的怎么样？谢谢！ |

temperature ranges (you can find out the equilibrium constant based on the
heat of solution).
Usually 1 day will be enough to reach equilibrium in a closed chamber of
course it depends on the kinetics (the relative size of the salt solution
evaporation surface and the volume of the closed space). |

和Alban Berg，特别喜欢后者的，他们有一种坚实有力的激情，在勃拉

As of some one gently rapping, rapping at my chamber door.

Only this, and nothing more."

这是一家视网膜专科研究所的网站：http://retinaspecialty.com/about-us/research/product-development/。这这里你可以看到药物送达视网膜的4种方式：直接注射，滴眼药水，全身给药和在眼睛周围埋至药物。至于是通过血循环还是非血液循环，我们不讨论。我认为两种都有。

在美国洛杉矶华人聚集区之一的蒙特利公园市，一项眼科健康调查（CHES：CHINESE
AMERICAN EYE STUDY）正在华人社区中展开。
奇怪的眼科检查
在美国定居多年的华人王丁（化名）参与了这项调查，现在他开始为这个调查感到百思
不得其解：“说检查眼睛为何要获取我的血样和DNA？”。
这一切要从9月说起，王丁当时接到CHES工作人员的电话，征询他是否愿意参加这项眼
科健康调查计划。60多岁的王丁眼睛不太好，当他看到这样的免费服务，而且又是当地
一家有名的眼科医院检测，他满口答应下来。
在当地，眼科检查至少要收取65美元的挂号费，如果再加一些眼科治疗，费用可能在几
百美元甚至上千美元，王丁说：“CHES不仅不收费，而且还承诺25美元的车马费。”对
很多像王丁这样的普通华人来说，这是一个诱惑。
王丁在电话里答应检查后，调查组的工作人员来到王丁的家里，对王丁的年龄、遗传病
