During the process of long-time adaptive evolution, wetland plants adopted a series of special strategies to acclimate to salt stress. The main strategies are: 1 life history adjustment, e. g., to adjust seed germination time, implement seed dormancy and viviparity, and change reproductive manner to escape from direct salt stress, 2 morphological adjustment, e. g., to adjust biomass allocation pattern, age stem, defoliate, and carnify vegetative organs to isolate the redundant Na(superscript +) to the inactive-metabolism shoots or exclude the Na(superscript +)from tissues; 3 anatomic adjustment, e. g., to sink stoma, develop aerenchyma, and thicken cuticle and phellogen to maintain normal photosynthesis and respiration; 4 physiological and biochemical adjustment, e. g., to exclude and excrete salt, compartmentalize ions, adjust osmosis, do selective absorption, regulate hormones, and induce antioxidative enzymes to maintain the osmotic equilibrium and eliminate the active oxygen in cell; and 5 molecular level adjustment, e. g., to start up many salt-induced genes to regulate the metabolic responses to salt stress.

在长期的适应进化过程中，湿地植物形成了多种适应盐胁迫的策略，主要有：1生活史方面，植物可通过种子萌发时间的调整、种子体眠、胎生、繁殖方式的改变等逃避盐度的直接伤害；2形态学方面，植物可通过生物量分配模式的调整、茎的老化、落叶及营养器官的肉质化等将多余的Na隔离到代谢不活跃的茎中或将其排出体外；3解剖学方面，植物可通过气孔下陷、发达的通气组织、增加细胞木栓层、角质层及栅栏组织的厚度等以维持植物正常的光合作用和呼吸作用；4生理生化方面，植物可通过离子区隔化、拒盐、泌盐、选择性吸收、渗透调节、激素调节及抗氧化物酶的诱导等来维持细胞内正常的渗透压，清除胞内活性氧分子；5分子水平方面，植物可通过多种与盐胁迫相关的基因来调控细胞内的多种代谢反应。

Nietzsche"s political philosophy is not piled up a dish of messy sand by maxim form, the writer thinks that Nietzsche"s political construction has his continuous logicality. It"s an expression of political philosophy that is constructed on the base of force will and life will, it makes life reach at a transitional bridge that can supply condition for the salvation of art. Thus, there are three understandings here. Firstly, politics is an objective expression of power will, also is an external expression of power will. The real politics depends on power will and services to their requirement and regulation; Secondly, the life faces on the double crises, on the one hand, the life falls into denial of Christian morality. Morality of Christianity presumes another world that life never touch for. This is world of soul belief and pursue, meanwhile, life is depreciated and degenerated as "evil", so the value of life suffers from misunderstanding and denial. Things of presence are subverted as things of exeunt."Uprising of slave in morality" results in the denial of ",master morality, at the same time, although modern democratic politics that based on morality of Christianity makes person return secular life and makes life identity and trite. This kind of politics creates privation of special vulture and race. On the other hand, internal requirement of power will results in the crisis of life because the characteristics of power will is continuous making and destroy.

尼采的政治哲学并非是以格言形式堆积而成的一盘散沙，笔者认为，尼采的政治建构有其一贯的逻辑性，体现为其政治哲学是建构在强力意志或生命意志基础上的并使生命达至艺术拯救提供条件的一座过度性桥梁，对此有三层理解：首先政治是权力意志的一种客观体现，是全力意志的一种外化，真正的政治必须立足于权力意志之上并服务于其要求和规定；其次，生命面临着双重危机，一方面，生命陷入基督教道德的否定之中，基督教道德设定了一个生命遥不可及的彼岸世界，这是灵魂信仰和追求的世界，同时生命被贬堕为"恶"，这样，生命的价值遭到误解和否定，在场的事物被颠覆为退场的事物，"主人道德"被否定，这是"道德上的奴隶起义"的结果，同时基于基督教道德之上的现代民主政治虽然使人回到了尘世，但是又将生命齐一化和平庸化，造成特殊文化和特殊种族的缺位，而正是这种文化和这种种族才能真正地肯定生命；另一方面，生命的危机是权力意志内在的要求所致，因为权力意志的一个特质就是连续地生成和毁灭，就生命本身就是权力意志而言，毁灭就是其必然的命运。

Hence, we first analyzed and studied the kinematics and dynamics of PDC bit, and that are utilized to analyzed how to hame cutters by PDC bit whirlpool. Onthe based of this, we do the cutting experiments. With the test, we not only think over the influence to force actting on cutters in rock nature, drilling parameter, cuttersdensity distributed, and also wear state of cutters and PDC bit appearance. Because the PDC bit's cutters are repeaded by polycrystalline-diamand and tungsten carbide, the specific property of PDC wear are not alike that of polycrystalline-diamand and not alike tungsten carbide.

因此，本文首先分析研究了PDC钻头的运动学和动力学，并利用分析的结果对PDC钻头的涡动是如何损坏切削齿的进行了探讨；在此基础上，进行了PDC钻头切削齿的受力实验，在受力实验研究中，不仅考虑了岩性、钻进参数、布齿密度等对切削齿受力的影响，而且考虑了切削齿不同的磨损状态、钻头的冠部形状对切削齿受力的影响；PDC钻头的切削齿是由聚晶金刚石层和碳化钨底层复合而成的，它的磨损特点既不同于金刚石的磨损又不同于碳化钨的磨损，因此，在分析了复合片磨损机理的基础上，进行了PDC钻头切削齿的磨损实验。

The results show that the compound conductive fiber has typical structure of sheath-core consists of black greened polyaniline electric conductive deposition as the skin and the white polypropylene matrix fiber as the core, which makes the compound fiber preferable physical mechanical property. The intensity and the elongation ratio of the electric conductive fiber are decreased but the thermal stability is enhanced after modified. The compound fiber has the good acid resistance but poor base resistance. The thermal stability of the compound fiber prepared by 4-methyl-benzene sulfonic acid is better than that prepared by hydrochloride acid. Moreover, the compound fiber can be re-doped by other organic or inorganic acid after freed from the adsorbed acid. Furthermore, the electric conductivity of the compound fiber decreases with the temperature increasing but hardly changed with the humidity. The adsorptive ability and therefore the content of the polyaniline, the constant of electric conduction, and the durability of the compound fiber can be enhanced by thinning the diameter, section heteromorphosis, section heteromorphosis and plasma treatment of the surface or blending with COPET of the fiber.

Phase-lagged cyclic boundary condition is implemented by a novel method in conjunction with the developed sliding interface technique to accurately simulate the arbitrary pitch ratio rotor/stator interaction without any modifications of the physics of the problem. It's for the first time to compose the computational area into one structured grids including both rotor/stator of centrifugal or axial turbomachinery with arbitrary pitch ratio. This method can eliminate the iteration of boundary conditions on the sliding interface and calculate the unsteady flow within rotor and stator simultaneously.
