点火

The first hot firing test of a reduced-scale demonstration version of a staged-combustion rocket engine has recently been achieved at the Lampoldshausen test facility of DLR.

he effect of the spark energy on the emissions was investigated on a small LPG SI engine (125 mL, 4stroke, watercooled, singlecylinder, with electronically controlled fuel injection).

结合四冲程、水冷125 mL单缸电控喷射摩托车发动机，对LPG在小型点燃式发动机上应用时，点火能量的改变对发动机排放的影响进行了试验研究。

However,it is the dissipa-tive mechanism,i.e.the mechanism of energy localization that attracts one′sattention for the problem of shock initiation.Since the test result of shock initia-tion about fine-grain explosive charge does not support hot spot ignition model,the author of this dissertation advances that the mechanism of energy localiza-tion is coincident with phonon-fracton crossover of fractal network for ultra-fine-grained charge and,moreover,analyzes the relation between shock sensi-tivity and porosity,which is consistent with shock Hugoniot curve for porousmaterials.

由于超细颗粒压装炸药的冲击起爆实验不支持热点点火模型，为此、本文提出对于单晶颗粒半径为微米以下量级的药床，冲击起爆的能量局域化机制与分形网络中弱局域化声子向强局域化分形子的渡越对应，并且根据这一机制分析了超细颗粒药床的冲击感度和孔隙度的关系，结果与多孔物质冲击压缩的P-V图吻合。

Results show that the propellant with α-HMX is easy to be ignited and its gas generation brisance and combustion rate is lower than that with β-HMX, and the burning rate pressure exponent of the propellant with α-HMX is 0.1 higher than that with β-HMX and mechanical properties of the propellant with α-HMX is worse.

结果表明：含α-HMX发射药点火容易，其气体生成猛度和燃烧速度比含β-HMX发射药的小，含α-HMX比含β-HMX发射药的燃速压力指数高0.1、力学性能差。

Ten minutes after blast-off the green light flashed and the chimpanzee was instructed to alter the course of the rocket slightly, to take infra-red photographs of Sweden and to repair the radio transmitter.

点火十分钟后，绿灯亮了，黑猩猩接到指令要稍稍改变一下火箭的飞行路线，拍下瑞典的红外线图片并修理一下无线电接收器。

The comparison between the solid bipropellant firing results and the monopropellant firing results appears to be quite good.

固体二元推进剂和单元推进剂的点火试验结果是很相近的。

While the ignite strategy of impulse engine is based on the measuring of shell roll angle.

而脉冲发动机的点火策略是以弹体的滚转角测量为基础。

I will set fire to Zoan, and inflict punishments on Thebes.

使帕特洛斯变为旷野，在左罕点火，对诺施行惩罚。

Plastic having a flammability rating of V-1 or better should meet the 15-second glowing wire without ignition.

塑料有易燃等级或更好的V-1应满足15秒发光的电线没有点火。

Also from 1954, this is another McCoy "9" but with a glow plug ignition.

此外，从1954年，这是另一种麦考伊& 9 &，但与辉光堵塞点火。

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。
