In this paper a thermodynamic method has been used to calculate the efficiency of coal liquefaction based on various kinds of coal. It is assumed that hydrogen source (both enthalpy and hydrogen) is provided from the same kind of coal, when it is converted into transportable fuel, Tue results from calculation for the most kinds of coal indicate that inorder to upgrade coal to fuel of H/C=1.6~2.2 the actual fraction of coal used for liquefaction is about 60~75%.

In this paper a thermodynamic method has been used to calculate the efficiency of coal liquefaction based on various kinds of coal. It is assumed that hydrogen source (both enthalpy and hydrogen) is provided from the same kind of coal, when it is converted into transportable fuel, Tue results from calculation for the most kinds of coal indicate that inorder to upgrade coal to fuel of H/C=1.6~2.2 the actual fraction of coal used for liquefaction is about 60~75%. According to the International Classification of Hard Coal, the coal class 4, 5, 6 and 7 have higher liquefaction effeciency; but the lignite containing much more oxygen gives the poor percentage effeciency.

本文假定在煤加氢液化制造液体燃料的过程中,原料煤和氢均由同一种煤提供。通过热力学计算,比较了我国几个煤种的煤炭在液化过程中液化效率的理论值。计算结果表明,液化效率大约在60~75%之间,其中,按国际硬煤分类的4、5、6、7类煤(相当于我国煤分类法中的气煤、肥煤、长焰煤、弱粘煤等)液化效率高,褐煤则由于含氧量高而液化效率低。

A newly discoved nitramine——1, 3, 3, 5, 5, 7, 7-hexanitro-1, 5-diazocydic octane(here after HCO),showing a property similar to HMX, is discussed in this investigation. The oxygen content of HCO is higher than HMX, and no crystalloblastesis has been found while being heated up to its melting point at 250℃ The theoretical specific impulse for HCO monopropellant is 269.28 s., 4 s., higher than HMX. Smokeless propellants with HCO all show to give higher specific impulse (theoretical) than those with HMX. Many new...

A newly discoved nitramine——1, 3, 3, 5, 5, 7, 7-hexanitro-1, 5-diazocydic octane(here after HCO),showing a property similar to HMX, is discussed in this investigation. The oxygen content of HCO is higher than HMX, and no crystalloblastesis has been found while being heated up to its melting point at 250℃ The theoretical specific impulse for HCO monopropellant is 269.28 s., 4 s., higher than HMX. Smokeless propellants with HCO all show to give higher specific impulse (theoretical) than those with HMX. Many new features are shown besides the relatively higher theoretical specific impulse. HCO propellants show much lower pressure exponent (a decrease of 0.109 without catalyst, or of 0.148 with the addition of catalyst; HMX propellants show a decrease of 0.129 with catalyst). It is certain that a even lower pressure exponent can be expected when suitable catalysts are being used. As a new type of smokeless propellant therefore, it is worthy of further investigation.

本文研究一种与奥克托金(HMX)相类似的新型硝胺化合物——1,3,3,5,7,7-六硝基-1,5二氮杂环辛烷(简称HCO)。这种硝胺炸药比HMX含氧量高,熔点250℃,加热时,在250℃温度范围内无晶型转变。HCO单元推进剂标准理论比冲比HMX单元推进剂约高4s。以HCO取代HMX作为无烟推进剂的高能添加剂,其理论比冲都高于HMX无烟推进剂。这种推进剂的燃烧性质比HMX无烟推进剂有明显改善,压力指数比HMX无烟推进剂低得多。无催化剂时,压力指数下降了0.109;加催化剂时,压力指数下降了0.148。而HMX推进剂只下降0.129,改进催化剂,其压力指数有可能进一步下降,故这种推进剂是有发展前途,值得进一步研究的新型无烟推进剂。

The defects formed in carbon rich CZ and EFG silicon after a 900℃, 160 or 560 minlong. phosphorous diffusion were studied with TEM. Besides misfit disfocations, numerousprecipitates were observed in the junction region in both materials. However. no precipitateswere found in the bulk. The precipitales in CZ had a larger strain field than those in EFG.The difference in the extent of the strain field of precipitates in CZ and EFG silicon can beascribed to the higher oxygen content in CZ silicon. It appears that oxygen is involved in theSi-self interstitial promoted precipitation of carbon.

用TEM研究了经900℃,160或560分钟磷扩散退火后的富碳CZ单晶硅和EFG(Edge-defined Film-Fed Growth)硅带中的缺陷。除错配位错外,在上述两种材料的P—N结区,均观察到大量的沉淀粒子,但在体内区域未发现沉淀粒子。CZ单晶硅结区内的沉淀粒子尺寸比EFG硅带中的大,它可归结为CZ单晶硅中含氧量高,氧增加硅中自间隙原子浓度,从而促进了碳的沉淀。
