炮眼

The other bank of the stream was open ground - a gentle acclivity topped with a stockade of vertical tree trunks, loop-holed for rifles, with a single embrasure/ through which / protruded the muzzle of a brass cannon / commanding the bridge.

河对岸是一片迹地，一片平缓的斜坡，斜坡顶有一道木桩直立的排栅，排栅上开着枪眼，有一架黄铜大炮从唯一的一个炮眼上探出炮口对着铁路桥。

The gunports were made with boolean substraction operation.

炮眼的制作应用了布尔运算。

In combined with the blasting parameter design for the sectional blasting with a full length borehole in the coal bunker,the paper certified the rationality of the millisecond time set by the method.

根据爆破自由面形成的时间和破碎岩石飞行的时间，探讨了深孔爆破各作用炮眼的合理延期时间；同时结合全深度一次钻孔分段爆破煤仓的爆破参数设计，验证了利用该法确定微差时间的合理性。

It is indicated that using the grade 2 coal mining permissible water-gel explosive at condign work face are provided with better blasting results and higher safety, and the arrangement of combining big cutting-borehole with small rest borehole can attain better blasting efficiency and smooth basting result.

试验表明：在条件允许的工作面使用煤矿许用二级水胶炸药具有较优的爆破效果和较高的安全性：采用大直径掏槽炮眼和小直径其它炮眼相结合的炮眼布置形式，可达到较好爆破效率和光爆效果。

By applying in seven spot, the directional control blasting technology by using slotted cartridgc has been confirmed that can increase the distance of hole in perimeter 50% on present basic, the ratio of half hole scar to 85%～95%, and the utilization ratlo of shot hole 10%.

通过在山东、山西、安徽、河南等省的七个矿区现场应用，证实了采用切缝药包定向断裂控制爆破技术，可使周边眼间距在现有基础上增加50％以上，周边眼的炸药单耗降低30～50％；循环炮眼数减少15～25％；炮眼利用率提高了10％以上；半眼痕率提高到85～95％；周边不平整度小于100mm，这一指标是目前国内外岩巷生产中最佳指标；每米岩巷掘进成本可降低200元以上，展现了定向断裂爆破技术广阔的应用前景。

Blasthole logging and supervision of blasthole sampling.

记录炮眼数据，并监督炮眼采样工作。

Circulation measurement of one-meter blasthole goes up with the increases of circulation explosive charge when circulation length of blastholes keeps the same, but the enhancement extent relatively becomes small with the increase of circulation blasthole length.

5在循环炮眼长度一定的情况下，增加循环装药量，单位炮眼进尺将得到提高，但提高的幅度随着循环炮眼长度的增加而相对地减小。

All gun- ports were open and the muzzles peeped wickedly from them.

所有的炮眼大开，炮口凶狠地从炮眼里伸出来。

All gun-ports were open and the muzzles peeped wickedly from them.

所有的炮眼都开着，炮口不怀好意地从炮眼里向外窥探。

All gun - ports were open and the muzzles peep ed wickedly from them.

所有的炮眼都开着，炮口不怀好意地从炮眼里向外窥探。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
