可倾斜的

A rotary separator of vacuum cleaner is composed of a dust collecting container, an opening-closing cover, and a separating plate dividing the dust collecting container into upper space and lower dust collecting chamber.

要約 本发明属于一种真空吸尘器用的旋转分离装置，包括含有异物的空气流入其内形成螺旋流的集尘箱，可开闭集尘箱的盖，集尘箱内设有分离板，分离板与集尘箱的下侧内周面严密地结合，在分离板的下部形成集尘部；分离板是中心开有开口部的圆锥状，从上面的圆周向下倾斜形成引导部，引导部的最下端有引导异物流入到上述集尘部的流入孔。

Because the direct roof of the No.92 ore-body is the backfilling of the No.91orebody which is the cementing materials or non-cementing materials, and there are no-filled mined-areas in someplace. So there are large-scale hidden troubles on the top of the No.92 slowly inclined large and thick ore-body, then we must find a new mining technology which aims at the complex mining condition of the No.92 ore-body. The cutting nature of the No.92 ore-body is very poor, so choosing the rational drilling and blasting parameters and enhancing the overall technological economic benefits are also the urgent problems waiting to be solved in the exploitation of the No.92 ore-body. The No.92 ore-body, thin lodes and the exploitation process of the No.91orebody influence each other, the geo-pressure phenomena aggravates obviously in case of the mined-areas increase constantly, and the geo-pressure problem will be more and more serious when the No.92 ore-body be exploited on a large scale in the next step.

由于它的直接顶板就是开采91号矿体时的胶结或者非胶结的空区充填体，部分地段甚至是未充填的采空区，使92号缓倾斜厚大矿体的上部形成大范围的隐患区，因此，必须针对92号矿体复杂的开采技术条件，寻找新的采矿技术与工艺。92号矿体的可凿性极差，选择合理的凿岩爆破参数，提高凿岩爆破工作的总体技术经济效益，也是92号矿体开采急待解决的问题。92号矿体与细脉带、91号矿体开采相互影响，目前在采空区不断增大的情况下地压显现有明显加剧的趋势，在下一步92号矿体大规模开采时，地压问题将越来越严重。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
