The best ink in the off-time after opening the packaging end use, not to open the ink on the outside when not in use Add to carton packaging, the cartridge so as to avoid talking about the dust falling into the hands of the next use of the dust caused by plugging into the nozzle first, the head following a reset state of ink wash sponge pad, open the front cover, press the Print Paper knife, move out, the hair can not suction clean cloth towel or sponge the ink pad, a large amount of about 10 days, then wash first, because each sponge pad is printer ink wash drawing of fatigue, if the dust and fatigue more ink will be solidified with the protection of Garra and print images will be the first flush, if the plug was found, and if the use of cleaning 3 seconds is not normal use, we must enter the printer maintenance menu kk2 or use kk1 cleaning, large format printers and a small printer operation principle is similar, if the correct maintenance and use, it will increase the service life, which Like is like a car, but also for us to maintain and are familiar with it

墨水最好在拆开包装后断时间内使用完，不要把打开的墨水放在外面，不用时包装好放入纸盒内，以免墨盒嘴上落入灰尘，下次使用时灰尘进入喷头造成堵头情况，喷头复位状态下面有一个洗墨海绵垫，打开前盖，按下打印切纸刀，往外移，用不起毛的纸巾或布吸干净海绵垫的墨水，用量大的话大约在10天清洗一次，因为海绵垫是打印机每次冲洗时吸取疲墨水的，如果灰尘多就会和疲墨水凝固在一起，对墨头的保护和打印头冲洗会有影像，如果发现堵头情况，如果使用清洗3秒还不能正常使用，我们要进入打印机的维护菜单用kk2或kk1清洗，大幅面打印机和小打印机的操作原理是差不多的，如果正确的维护和使用，它的使用寿命就会增长，这也好比一辆轿车一样，还要我们去维护和熟悉它

Dust and aspiratory dust were monitored personally on the full-mechanized mining work face, full-mechanized tunneling work face and gun tunneling work face in the coal mine to investigate the harm of aspiratory dust to the workers underground.

针对呼吸性粉尘对矿井工人身体健康的危害，对煤矿综采工作面、综掘工作面、炮掘工作面等进行分工种个体性的全尘和呼尘监测，测定了各工作面粉尘的浓度、粉尘分散度和SiO2浓度。

These samples were collected along a main street across the urban area and a mountain route from foot to the top. Results demonstrate that the main magnetic minerals in the street dust are magnetite, maghaemite and haematite with some paramagnetic minerals. Plots of Mrs/Ms vs. Bcr/Bc and Xfd % vs. X ARM/SIRM indicate that the main grain size of magnetic minerals in the street dust are pseudo single domain. The results reveal that the Lanzhou city is more polluted in spring than in summer. The main pollution sources are anthropogenic activities （81.9%） and natural dust （18.1%）, especially the former. The spatial distribution of pollution is controlled by the topography and weather conditions.

结果表明，兰州市街道尘埃中磁性矿物含量较高，主要磁性矿物是铁磁矿、磁赤铁矿和赤铁矿，并伴有少量顺磁性矿物；磁性矿物粒度主要是准单畴；市区污染春季较夏季严重，春季高频率的强沙尘暴可能带来了更多的磁性矿物；兰州市污染物的沉积和分布在很大程度上受到气象条件和地形地貌格局的影响，市区每个盆地东端高于其它地区；兰州市污染以人为活动产物为主，人为活动贡献约为81.9％，其中包含交通约22.6％的贡献，自然降尘贡献约为18.1％；特殊的地形和气象条件，使得兰州市区的大气环境容量比平原城市的环境容量小得多，进而导致严重的大气污染。
