ZT 守住清贫，就守不住家 小姨说，人生就像打麻将，起先你抓了一张牌留在手里，满以为这盘能整个杠上花，结果到最后，就是这张牌拖累了你没能和成。 姨夫就是小姨抓错的那张牌。 我见过小姨刚高中毕业时的照片，她穿淡黄色连衣裙，靠着一棵斑驳的白杨树，白净的脸上带着婴儿肥，露出一双充满浪漫与幻想的眼睛。 那时候的小姨酷爱言情小说，最喜欢的作家是琼瑶和严沁。恰是这一年，村支书带着一个刚毕业的师范生来写计划生育...

智能割草机专用标准，iec60335-2-107{ed1.0}2012.pdf
智能割草机专用标准，iec 60335-2-107，
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of machines when operated as in normal
use taking into account the manufacturer's instructions. It also covers abnormal situations that
can be expected in practice and takes into account the way in which electromagnetic
phenomena can affect the safe operation of machines.
This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the machine is connected to the supply
mains. However, national wiring rules may differ.
If a machine within the scope of this standard also incorporates functions that are covered by
another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as far
as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
