我在Minnesota,冬天很冷,暖气基本24小时开着。humidity设得高,有利于保护木地
板,可是早晨起来窗户上都有水汽;humidity设得低,窗户上倒没有水汽,但是木地板
又要裂开。有一点可以肯定木地板裂开跟湿度有关,夏天除非被太阳直接晒,否则木地
板不会裂开。
不知大家在冬天怎么保护好木地板?
另外,买了一个有steam sanitization 既可以当 mop,又有vacuum功能。先用vacuum吸
木地板,然后打开steam, mop木地板。可是买房子时的agent说,用带steam mop 木地
板不好,有水蒸汽通过裂缝进入木地板,也会出现问题。
版上也有人提到,对新的木地板,先要弄一保护层,然后才能拖地板。
这么说,买那种带steam sanitization 的vacuum岂不是没有什么用?
木地板出现裂缝,也不知怎么弄,还是不管,等到夏天自己就会缝合?
问了一堆问题,谢谢答复。

Seller's disclosure
Attic, Basement and Crawl Spaces
Are you aware of any water leakage, accumulation or dampness within the
basement or crawl spaces or any other areas within any of structure on the
property?
SELLER 打了勾,我以为是漏水去询问,她加的解释
At one time slight dampness observed due to humidity,No leakage ever
observed.
后来跟AGENT沟通, 对方LISTING AGENT 是新手,Seller 估计比较诚实
这个At one time slight dampness observed due to humidity是哪儿都有吧》》》第
一次买房没经验,特来这请教。看来问题不大。

Temperature sensors can definitely fit into a small cavity, e.g.,
theromcouple. Now sure about humidity sensor.
Intuitively, I believe there are lots of temperature sensors in bare dies,
since they can be wrapped in a package and the heat can still sip though. I
am not sure how a humidity sensor can be sold in bare die, since the
sensing part most probably would need to be exposed to outside, and I doubt
there would be any IC with exposed die...

按照科学规定室内温度是不得高于72的 否则会有人生病
Owing to variations in humidity and likely clothing, recommendations for
summer and winter may vary; a suggested typical range for summer is 23 °C (
73 °F) to 25.5 °C (78 °F), with that for winter being 20 °C (68 °F) to
23.5 °C (74 °F).[2] Although by other considerations the maximum should be
below 24 °C (75 °F) – and for sick building syndrome avoidance, below 22
°C (72 °F).[2]

开,建议我用mdf的。但4.25" chaleston crown moulding mdf 的profile远不如pine

running joints instead of simple butt joints. 但又不知怎么和中国师傅解释这些

这种计算humidity的公式很奇怪,
LA is NOT HOT all the time!!! People think it is like Florida or NY in the
summer. It is not. In most areas of LA, it is hardly ever less than 60 and
rarely more than 80. It cools down at night and you almost always need at
least a light sweatshirt - even in the summer.
The more inland you are the warmer it is. And the Valley is much hotter.

What do you need to know about reducing humidity with your central AC unit?
Humidity in the winter is a good thing. Humid air holds more heat, keeps you
healthy, keeps those pesky winter bugs at bay, and keeps your furniture
from drying out. But what about during the summer? It’s a whole different
story.
Humidity holds heat, which means humid air works against your air

Humidity, the amount of moisture in the air, is relevant to
plant growth. Humid conditions and still air are very
conducive to fungal and bacterial infections in potted
plants. Keep plants in places with good air circulation as
the air is fresh and not stagnant, and the humidity is

多。
硅酮不是热塑性的,有很多聚合的方法,所以打印应该不成问题。比如家用的sealant
大管子我猜是跟空气里的水蒸气接触以后自发聚合的。
The air temperature and humidity in the air can affect how long a silicone
caulk takes to cure or an acrylic caulk to dry. A silicone caulk will cure
slower when it is cool and the air is dry (low humidity). An acrylic caulk
will dry slower when it is cooler out or more humid. Make sure to vary your
wait time based on the humidity level.
