Shock wave compression technique has play an important role in the understanding of the material composition thermodynamic state and physical properties of the earth ' s ulterior . in this article , the stabling of high - pressure phase of one of the main candidate materials of the earth ' s lower mantle ? enstatite ( mg0 . 92 , fe0 . 08 ) sio3 were investigated through the experimented measurement of hugoniot equation of state , and together with thermodynamic calculation and analysis 本學位論文以沖擊壓縮技術為手段，從測量其hugoniot物態方程入手，結合高壓物理和熱力學理論分析，較深入地研究了下地幔中的一種主要候選組分頑火輝石( mg _ ( 0 . 92 ) ， fe _ ( 0 . 08 ) ) sio _ 3在與下地幔大致相當的溫度壓力條件下的相態-鈣鈦礦型結構的相穩定性。 |

The main work and achierement are as following : ( 1 ) by using shock impedance matching technique and electric probe method , 5 shots of impact experiments were conducted to measure the hugoniot equation of state for enstatite ( mg0 . 92 , fe0 . 08 ) sio3 with the average initial density 3 . 05g / m3 from shock pressure 50 gpa to 115gpa , using two stage light gas gun 本文研究取得的認識主要有以下幾點： ( 1 )用阻抗匹配法和電探針技術在80 115gpa壓力范圍內對平均初始密度為3 . 05g / cm ~ 3的頑火輝石樣品進行了5發hugoniot狀態實驗測量。 |

( 4 ) the hugoniot of the mixture of mgo ( mw ) and sio2 ( st ) were calculated by the additire principle of hugoniot for mixture , and compared with the experimental hugoniot of enstatite . the results shows that there exists large difference between both d - u relationship and p - n curve for the two hugoniot 516u （ 4 ）用混合物hugongiot線的疊加性原理計算了mgo （ mw ）和引。 （ st ）混合體系的hugongiot線，經過與頑火輝石實驗hugongiot數據對比，無論是從心關系還是從一產關系上看兩者均有較大差距。 |

Considering that no phase transition of enstatite with perovslite structure were found during these static high pressure experiments , the consistence of the bulk modulus also supports that the high pressure phase of perovskite structure of enstatite is stability between 50 - 140gpa 考慮到靜高壓下的數據是在實驗中未發現頑火輝石高壓相有相變的情況下得到的。因此，動高壓與靜高壓實驗數據的一致性支持了在80 ? 140gpa壓力內預火輝石的高壓相保持穩定的觀點。 |

The linear relationship between shock wave velocity d and particle velocity u of our samples were obtained : d = 3 . 701 + 1 . 527u there the unit of relocity is km / s . no phase transition shows for enstatite with perovskite structure according to the experimental linear d - u line up to 110gpa 實驗結果表明，在80 115gpa壓力范圍內本文所用頑火輝石的沖擊波速度d與粒子速度u可用線性關系： d = 3 . 247 + 1 . 626u來描述。 |

So it is impossible for enstatite to decompose to oxides between 50 to 140gpa . ( 5 ) the bulk modulus k0s and its first derivative of pressure k0s “ were calculated from the experimental hugoniot data , by using eularian limit strain theory 3 ）根據本文頑火輝石hugoniot實驗數據（結合前人的實驗數據l用歐拉有限應變理論計算得到的頑火輝石零壓炸彈性模量及其對壓力的一階導數為： k叮一266gpa ， k ； ，二4 |

( 3 ) by using the new method put out in ( 2 ) , hugoniot data of no - porous samples of enstatite ( mg0 . 92 , fe0 . 08 ) sio3 which initial density is 3 . 273g / m3 , were reduced and the modified hugoniot data shows very small dispersivity （ 3 ）用（ 2 ）中提出的新方法，對前人和本文的頑火輝石hugongiot實驗數據進行了初始孔隙度修正。結果顯示，不同研究者所得的hugongiot數據的分散性大大減小。 |
|
The relationship between shock wave velocity and particle velocity of no - porous enstatite can be expressed as : d = 3 . 771 + 1 . 516u where the unit of velocity is km / s 可以認為，從p phugongiot數據看，在50 160gpa范圍內，頑火輝石的高壓相是穩定的。 |
