The primitive Material which the Earth consists of is probably IAB iron meteorite (core of the Earth) and H-group chondrite (mantle of the Earth). When the experimental temperature is higher than 1300℃, noticeable magmatic differentiation took place in the Jilin chondrite, and this is quite similar to the process of the formation of the core and mantle of the Earth.

The primitive Material which the Earth consists of is probably IAB iron meteorite (core of the Earth) and H-group chondrite (mantle of the Earth). When the experimental temperature is higher than 1300℃, noticeable magmatic differentiation took place in the Jilin chondrite, and this is quite similar to the process of the formation of the core and mantle of the Earth. The metal-sulfide components within chondrite would sink to the core. During melting and recry-stallization of the Jilin chondrite the partial FeO in olivine can be reduced and Fe 0 formed. These metal Fe also would move to the core.Some large parent meteorite bodies seem to have undergone such a process leading to the formation of some iron meteorites and achondrites. The Fe-Ni-S phase in the experimental products may serve as a indicator in identifying the cosmic chondrules.

组成地球的初始物质很可能是IAB铁陨石及H群球粒陨石,非均匀吸积形成地球以后,除由岩浆分异作用使幔中金属-硫化物下沉到原始地核外,在还原条件下还有部分Fe是由橄榄石中的FeO还原为Fe°而提供的并加入于地核内.对于大的陨石母体,由于内部加热或其表面受冲击加热而发生熔融和岩浆分异,导致形成某些铁陨石及无球粒陨石或7型岩石类型的球粒岩石.实验产物中的Fe-Ni-S相可作为判别宇宙球粒的标志之一. 我们曾报道过吉林陨石热变质实验研究结果~[1],根据在高温高压条件下吉林陨石的岩浆分异作用,初步探讨了类地行星金属与硅酸盐分离的机制及其核-幔的形成过程~[2].最近,我们对吉林陨石全岩熔融实验产物中的硅酸盐矿物及金属相进行了较系统的电子探针分析和研究.本文试图根据其实验产物的矿物成分特征进一步探讨组成地球初始物质的演化过程及普通球粒陨石与某些铁陨石和无球粒陨石的成因联系.

To counter the explosion in borehole of well Chuan-48 without open fire source, the reasons causing such an explosion are analysed in this paper, namely: under high pressure conditions in the borehole, a little air can form an explosive gas and both the static charge collection at well bead and adiabatic compression of the air in the lubricator can be turned into firing condition. In view of this, the measures for preventing such an accident are given out.

The present work has studied the effect of hyperbaric N_2-O_2 saturation diving at the depths of 36.5 meters and 50 meters on ventilatory response to CO_2.13 healthy men were tested and divided into two groups.Rebreathing method was used to measure the ventilatory responses.During N_2-O_2 satura- tion diving,Po_2 was constant about 0.30ATA.When the ventilatory respon- ses to CO_2 were measured,Po_2 was about 0.93ATA,and Pco_2 was about 0.07 ATA.others were Nitrogen in the inhaling gases.Beside,the partial press-...

The present work has studied the effect of hyperbaric N_2-O_2 saturation diving at the depths of 36.5 meters and 50 meters on ventilatory response to CO_2.13 healthy men were tested and divided into two groups.Rebreathing method was used to measure the ventilatory responses.During N_2-O_2 satura- tion diving,Po_2 was constant about 0.30ATA.When the ventilatory respon- ses to CO_2 were measured,Po_2 was about 0.93ATA,and Pco_2 was about 0.07 ATA.others were Nitrogen in the inhaling gases.Beside,the partial press- ure of CO_2 of the end-tidal was measured.The results were as follow: 1.The slope of ventilatory response to CO_2 declined with the rise of ambient pressure in all of the subjects. 2.The intercept of ventilatory response to CO_2 did not change at the different depth. 3.Under the hyperbaric environment the increase in the partial press- ure of end-tidal CO_2 was more significant than the control. All changes of slope of ventilatory response to CO_2 and partial pressu- re of the end-tidal CO_2 could return to the values of sea level at the end of decompression.It was suggested that under hyperbaric condition the de- crease of slope in ventilatory response to CO_2 might result either from in- crease in respiratory resistance or from change in sensitivity of CO_2 in re- spiratory centre or both.

本工作研究了36.5米和50米氮氧饱和暴露对人体二氧化碳通气反应的影响。用重复呼吸法测定了两组共13名健康男性受试者的二氧化碳通气反应。氮氧饱和条件下的氧分压维持在0.30绝对压左右,而测定通气反应时的吸入气中的氧分压是0.98绝对压,二氧化碳分压是0.07绝对压,其余为氮气。此外,还测定了受试者的终末潮气二氧化碳分压。实验结果表明:1.二氧化碳通气反应随压力升高而下降。2.二氧化碳通气反应曲线的截距在不同深度均未见有明显的变化。3.在高压条件下,静息状态的终末潮气二氧化碳分压比常压对照值有明显的增加。高压下的二氧化碳通气反应的下降和终末潮气二氧化碳分压的升高,在减压返回海平面后均能恢复到常压水平。高压下的这些变化,可能是呼吸中枢对二氧化碳敏感性的改变所致,也可能是由于呼吸阻力增加引起的呼吸功增加所致,或是两个因素叠加的结果。
