It was pointed out that the diameter of the powder core of safety fuse was themain factor for its combustibility by a discussion of the combustion mechanism of the black powder, and the on-line testing significance of the diameter of the powder core was also described inthis paper.

文章通过对黑火药燃烧机理的探讨，指出黑火药药芯直径是影响导火索燃烧性能的主要因素，阐明了药芯直径在线检测的意义，并扼要介绍了一种光电式检测器的工作原理及其应用。

Generous smell of prune, blackberry, black cherry, peony, and scrubland.

The experiment of tagging and releasing Sparus macrocephalus was carried out in 2004,2005 and 2006 using three tagging methods of coded wire tag,visible implant elastomer tag and scutcheon tag respectively in the Zhoushan sea area.

2004年-2006年分别采用金属线码标记、荧光色素可见式标记和挂牌标记三种方法，在舟山海域进行黑鲷标志放流试验，三年内共放流标志黑鲷17 616尾，平均体长131。

The mortality and lost tag rate of scutcheon tag is the highest of all, The fish with visible implant elastomer tag and scutcheon tag were recaptured in the same year and the recapture rate were 0.16 % and 0.64 % respectively, and there was no recapture of fish with coded wire tag. All the results showed that in the open sea area the recapture rate was low, and the wire tag was not fit for the tagging and releasing of Sparus mcicrocephalus. Otherwise, the migration area of the tagged Sparus macrocephalus was small and the longest distance was 15 nautical miles and the territorial habitat was distinct. In addition the tagged Sparus macrocephalus grow slowly in 2 months after being released and then grow faster.

结果表明：挂牌标记的死亡率和脱标率最高，荧光和挂牌标志鱼只获得当年回收，回捕率分别为0.16%和0.64%，没有捕获金属线码标志鱼，说明在开放性的水域，总体回捕结果不佳，金属线码标记法不适合黑鲷放流；标志黑鲷移动范围不大，最远不超过15海里，栖息地具有明显的区域性；标志鱼放流后2个月左右生长缓慢，此后生长加快。

The experiment of tagging and releasing Sparus macrocephalus was carried out in 2004, 2005 and 2006 using three tagging methods of coded wire tag, visible implant elastomer tag and scutcheon tag respectively in the Zhoushan sea area. In 3 years, 17616 Sparus macrocephalus with average body length of 131.9 mm and average body weight of 46.46 g were tagged and released.

2004年－2006年分别采用金属线码标记、荧光色素可见式标记和挂牌标记三种方法，在舟山海域进行黑鲷标志放流试验，三年内共放流标志黑鲷17 616尾，平均体长131.9 mm，平均体重46.46 g。

Solar collectors for the selective absorption of high-coating the introduction of Germany technology into the market, this new type of titanium-based and quartz-blue coating, a one-time use of ionizing coating process, as opposed to the widespread use of The black chrome plating and black nickel coating, in terms of performance on an unparalleled advantage.

用于太阳能集热器的高选择性吸收体涂层引进德国技术进入市场，这种新型的基于钛基和石英的蓝色涂层，采用了一次性电离涂层工艺，相对于普遍使用的电镀黑铬和黑镍涂层来说，在性能上具有无可比拟的优势。

Based on generator self excitation theory and the characteristics of black-start, we choose this simple method to be the criterion of generator self excitation problem in black start. Later, simulation of hydraulic generator self-excitation study is given.

从适用於黑启动快速这一特点出发，在已有的方法中选择了一种简单的近似方法来作为黑启动研究中自励磁产生与否的判据，从自励磁现象本质出发进行了阐述，并对水轮机组自励磁产生的暂态过程进行了仿真计算。

With reading a mass of the documents about the rolling resistance and wet anti-grapping, there are 11 types semisteel belt tyres formularies designed in this paper by changing carbon black and SBR1502/SBR1712/BR9000 blending ratio, which answer for the actual demands of the tyre industry and have a certain extent engineering practicability.The DMA curves of 11 types tread rubber materials used in tires with the changes of temperature have been obtained by using Dynamic Mechanics Analysis technique on NETZSCH DMA242 instrument.

本文采用动态力学分析法，使用NEZSCH公司生产的DMA242型实验仪，获得了11种胎面胶的DMA温度曲线，从炭黑和生胶配比变化两方面，分组对不同系列的胎面胶的储能模量—温度曲线和损耗因子—温度曲线进行了分析比较，并参照1#胶料，对11种胎面胶—10℃～10℃和50℃～80℃的tanδ进行比较，讨论了炭黑及SBR1502/SBR1712/BR9000并用比的改变对胎面胶滚动阻力、湿抓着力的影响；在动态力学分析实验的基础上，还获得了11种胎面胶的生热率曲线，并分组进行了比较，研究了配方与生热率的关系。

When a diamond is dark gray, a very dark green or truly black, it is referred to in the trade as a "black diamond." Such a stone may be opaque to nearly semitransparent.

当一个钻石是灰黑，极深绿还是真正黑色这是指在贸易作为"黑钻石"这种石头可能接近半透明不透明。
