Further, we investigated the possible impact of SDP on ENSO event in interannual scale by researching the anomalous characteristics of sea temperature, wind, convergence and divergence, total cloud amount, radiation and so on. The results showed that the influence of SDP on ENSO involve not only the process of positive and negative air-sea feedback, but also the interaction between atmospheric circulation over tropical and subtropical, specially the eastward propagation of anomalous zonal wind from the equatorial Indian Ocean to the Pacific Ocean. Otherwise, it also relates, to some extent, to the transition of large-scale climatic mean flow over the Indian Ocean and Pacific Ocean.
进一步,本文通过分析SDP事件前后期海温、高低层风、低层辐合辐散、高空云量和辐射等的变化特征研究了南印度洋偶极型海温异常在ENSO事件中的作用,结果表明:SDP在ENSO事件中的作用不仅涉及海气相互作用的正负反馈过程,还与热带和副热带大气环流之间的相互作用有关,特别是与东南印度洋海温变化所引起的异常纬向风由赤道印度洋向赤道太平洋传播的过程等有十分直接的关系;同时,SDP对ENSO事件的影响在很大程度上还依赖于大尺度平均气流随季节的变换。

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。

通过数值分析,模拟了塔中Ⅰ号断裂带和塔中45井三维模拟区O〓灰岩的构造应力场和应变场,结果表明:研究区主应力方向为北东~南西向,第二期的构造扭动使其由北向东发生了一定的偏转,但总的方位变化不大;O〓~S~D时期,塔中地区构造运动较强,研究区大部分处于高应力状态,岩石破裂程度较高,而岩芯观察结果也证实了这一结果,即O〓灰岩地层中早期形成的构造结构面比较发育,单个结构面的规模也较大;C~P时期,岩石的破坏程度较早期有所提高,主要表现在两个方面,一是各局部区岩石的破坏程度普遍有所提高;二是各个级别破裂区的分布范围相应地扩大了;研究区应力分布表现出明显的不均匀性,特别是剪应力,无论是O〓~S~D时期,还是C~P时期,都有很大的差异性,特别是在小断层的端部,剪应力比较集中,而且在断层的两盘,剪应力方向和大小都变化极快。

The results showed that glucose and fructose are primary soluble sugars from night to 10: 00 a.m. in mature leaves, but during 13: 00 - 16: 00 p.m., stachyose becomes the most abundant oligosaccharide, this diurnal change is mostly due to the tempestuous fluctuation of stachyose concentration in mature leaves. During photoassimilate transportation, the p rimary soluble sugar in phloem sap is stachyose. When transportation is finished, sucrose becomes the main sugar in phloem sap. Cucumber leavesmay store photoassimilate in the forms of starch, glucose, fructose, stachyose and sucrose at night. The concentrations of glucose, fructose and stachyose in phloem sap are much lower than in leaves at that time. There may be some unique mechanisms modulating source-sink translocation by which soluble sugars in leaveswere prevented from loading into the phloem further during night.
结果表明夜间至上午10: 00,葡萄糖和果糖是叶片中主要的可溶性糖,而下午13: 00至16: 00,水苏糖成为成熟叶片中含量最高的可溶性糖,这种变化主要由叶片中水苏糖含量剧烈的昼夜变化引起;当黄瓜同化物从源叶向外运输时,韧皮部汁液中的可溶性糖以水苏糖为主,运输完毕后则以蔗糖为主;黄瓜成熟叶片在夜间以淀粉、葡萄糖、果糖、水苏糖、蔗糖等各种形式贮藏尚未运出的同化物,而此时韧皮部汁液中葡萄糖、果糖、水苏糖的含量极低,可能有特定的源库调节机制阻止叶片中的可溶性糖在夜间进一步向韧皮部中装载。

Based on the simulation data, the effects of clearances, damping coefficient and the rotation speed on the dynamic behaviors are studied: compared with ideal mechanisms, mechanisms with clearances are less stable; as for mechanisms with clearances, when the crank rotates at the speed of 100rad/s, the actual clearances are always above the radium of clearances, axle pin and axle cover keep contact throught the rotation; when the crank rotates at the speed of 20rad/s, mechanisms are in an unstable state, at an angle of about 300, the actual clearances are below the radium of clearances, pairs lose contact, which results in collision between them; with the speed of 20rad/s, when damping coefficient is assumed 175Ns/m, distinct separation and collision happen between pairs; when damping coefficient is assumed 220Ns/m, separation and collision are controlled.
在含间隙机构中,当曲柄以100rad/s转动时,运动副间隙始终大於半径间隙,轴销与轴套始终保持连续接触;当曲柄以低速20rad/s转动时,系统处於极不稳定的震荡状态,在转至300°左右时,运动副间隙小於半径间隙,脱离接触,发生明显的分离碰撞现象。在含间隙机构中,曲柄以低速20rad/s转动,当取法向阻尼系数为175Ns/m时,副元素发生明显的分离碰撞现象;当取法向阻尼系数为220Ns/m时控制了副元素的分离,副元素一直处於连续接触状态。
