2Nd, thorough analysis: The Earth may say is an extremely marvelous thermonuclear reactor, when the earth interior pressure achieved certain critical, in the Earth material may decay the nuclear matter is called as the thermonuclear material, can have the thermonuclear reaction, thus has the huge energy, then the melted partial materials, form the rock magma are the liquid state materials, this response stratification plane is possibly many stratification planes, first possibly is located between the earth's crust and the mantle, upward next two transfers, displays for the light density material diastrophism as well as density upper mantle material phenomena and so on solidification; Under second possibly is located between the mantle and the core, the pressure is more formidable, causes not not easily to have the thermonuclear reaction thermonuclear material to have the response, forms the relative quite stable liquefied material level, simultaneously is upward next two transfers, forms the counter-flow phenomenon which the high density under mantle as well as the high density core material contact liquefies and is far away cools; These material periodicity regular movements and so on convection as well as Earth polar axis rotation are possibly the basic source powers which the terrestrial magnetic field produces.
深入剖析:地球可以说是一个非常奇妙的热核反应堆,当地球内部的压力达到一定的临界,地球物质中可衰变的核物质统称为热核物质,就会发生热核反应,从而产生巨大的能量,进而融化部分物质,形成岩浆即液态物质,这个反应层面可能是多个层面,第一层可能位于地壳与地幔之间,向上下两边对流,表现为轻密度物质的地壳运动以及中密度上地幔物质的固化等现象;第二层可能位于下地幔与地核之间,压力更为强大,引起不易发生热核反应的热核物质发生反应,形成相对比较稳定的液化物质层,同时向上下两边对流,形成中高密度的下地幔以及高密度地核物质的接触液化和远离冷却的对流现象;这些对流以及地球极轴自转等物质周期性规律性运动可能是地球磁场产生的根本源动力。

The results indicate that the different thermal expansions and elastoplastic properties and distributed randomness of various mineral particles composed of oil shale will lead to the nonuniformity of thermal field, deformation field and stress field in heating process, which makes the particles of oil shale deform incompatibly: and the release of product pyrolysis results in irreversible damages of oil shale material and structure. These are the main reasons for the thermal fracture of oil shale. When oil shale is heated through thermal conduction, temperature transfers slowly, so the spacing between heating well and production well should not be kept too long. When difference exists in oil shale reservoir's properties, heating well should be chosen in the high conductivity region. Oil shale's stratification is vital for developing permeation zone in in-situ retorting. Oil shale will generate additional expansion force as it reaches its pyrolysis temperature, and stratification will be cracked first, so the oil shale stratification should be utilized to enhance its permeability.
研究结果表明:组成油页岩各种矿物颗粒热膨胀和弹塑性性质的不同及其分布的随机性,导致油页岩加热过程中温度场、变形场和应力场的非均匀性,使得油页岩颗粒间变形不协调和油页岩热解产物释放引起油页岩材料与结构性能发生不可逆的劣化损伤,这是油页岩发生热破裂的主要原因;热传导方式加热油页岩,温度的传递比较缓慢,加热井和生产井的间距不宜过大,对油页岩储层性质存在差异时,注热井应选择较高热导率的区段;油页岩的层理对油页岩地下原位开发形成渗透带至关重要,油页岩达到热解温度会产生附加的膨胀力,首先在层理处开裂,应充分利用油页岩层理赋存条件改造其渗透性。

The aim of this study was to develop a novel amphiphilic functional block poly(ε-caprolactone) bearing ketone groups MPEG-b-P(OPD-co-CL. 2-oxepane-1, 5-dione was copolymerized with ε-caprolatone in which methoxy poly (MPEG, Mn=5 000) and stannous octoate were used as initiator and catalyst, respectively. The syntheses were conducted by bulk and solution polymerization. 1H NMR results showed that peak position and splitting of the polymers synthesized through solution polymerization were consistent with theoretical data, demonstrating the products were designed block copolymers. While in the bulk polymerization, polymer peak position was changed due to their high reaction temperature, suggesting their structural variation.

The pilot study shows that the ammonia dissociation/synthesis reaction is inherently free of any potential side reaction problems, and also offers phase separation of products. The carrier of heat store is liquid. and is very interesting for long-term storage as it can be carried out at room temperature with no energy losses, Its theoretics energy storage density reachs 66.5kJ/mol, which outclasses sensible or latent heat storage. In comparison to other thermochemical energy storage, ATCES needs lower temperature in endothermic reaction(only 650℃), but It can produce over 550℃ high temperature stream in exothermic synthesiser. Furthermore, the heat store/recovery can change with adapt to the heat source/load automatically, and offers coninuous(24 h) production of heat, These advantages will see a rapid increase in the adoption of large-scale concentrating solar thermal power generation.

Whereas the seismic thermal lithosphere is about 150km thick, which means the Tarim lithosphere is not steady and became thinner. In this paper, writers analyzed the Tarim lithosphere thinning mechanism based on the tectonic thermal evolution quantitative method, and discussed three possibilities:the hotter India asthenosphere intruded under the Tarim lithosphere and made the Tarim lithosphere became unsteady;the bottom of Tarim lithosphere is heated by friction of the atheonosphere flow and washed off by the hot asthenosphere; the Xizang lithosphere delamination induced the convection, and the upflowing mentle heated the bottom of the Tarim lithosphere and make it enthinning.
本文利用构造热演化方法对塔里木岩石圈减薄的热演化过程进行了定量分析,探讨了塔里木盆地岩石圈减薄可能的三种机制:印度板块与欧亚板块碰撞后青藏高原岩石圈底部的软流圈较塔里木盆地岩石圈底部的软流圈的温度要高,青藏高原的软流圈地幔向塔里木盆地岩石圈底部侵入形成的热扰动使得塔里木盆地岩石圈底部的温度升高;塔里木岩石圈与其下流动的软流圈的摩擦剪切生热导致其岩石圈地幔底部温度升高,使得岩石圈底部发生热侵蚀,从而使得与软流圈接触的岩石圈地幔不断地加入到软流圈地幔;在塔里木盆地岩石圈的下部,青藏高原的岩石圈在该处发生了拆沉,从而诱发的软流圈地幔对流,上升的软流圈地幔流使得岩石圈地幔的温度升高而熔融,成为软流圈地幔。
