尼亚加拉瀑布的水流冲下悬崖至下游重新汇合之后，在峡谷里继续翻滚腾跃，在不足2公里长的河段上以高于大瀑布的流速每小时35.4公里跌荡而下15.8米的落差，演绎出世界上最狂野。最恐怖。最危险的漩涡急流，又冲进深38的漩涡潭，然后一个蛟龙翻身，经过左岸加拿大的昆斯顿。右岸美国的利维斯顿，冲过"魔鬼洞急流"，沿着最后的"利维斯顿支流峡谷"由西向东进入安大略湖。

Would God I were the tender apple blossom That floats and falls from off the twisted bough, To lie and faint within you silken bosom, Within your silken bosom as that does now! Or would I were a little burnish'd apple For you to pluck me, gliding by so cold, While sun and shade your robe of lawn will dapple, Your robe of lawn, and you hair's spun gold. Yea, would to God I were among the roses That lean to kiss you as you float between, While on the lowest branch a bud uncloses, A bud uncloses, to touch you, queen. Nay, since you will not love, would I were growing, A happy daisy, in the garden path; That so your silver foot might press me going, Might press me going even unto death.

愿神将我化为纤弱的苹果花由交错的枝干飘零而下停驻沈溺在你温柔的胸怀那温顺一如今日的胸怀或愿是那光亮的小苹果让你摘下，轻轻抚拭点点树影洒向你宽松的软洋纱长袍软纱长袍，金色秀发啊，愿神让我身在玫瑰花丛当你流连其中我就能俯身吻你在低低的枝桠上有一朵含苞蓓蕾一朵含苞花蕾，轻轻地触碰了你，我的女王唉，当你不再爱了，我也将成长长成一株快乐的雏菊，隐身於花园小径中而你的银白纤足却会踩著我向前行你那无情、致命的步伐呀。。。

At the normal state, porphyrin molecules do not have EPR signal. However, light excitation may cause a transition of porphyrin molecules from singlet to triplet. At the same time, the change from diamagnetism to paramagnetism occurred to porphyrin molecules. In this case, the two un-paired electrons are nearby each other and cause a strong interaction, giving EPH signal with sharp peak at g = 2.000. The g value increased with an increase in electron cloud density.

Through designing of composition and structure of the bioactive graded coating,innerstress and its distribution in the coating were analyzed and calculated, the resultsshowed that when composition distribution coefficient n was 1.5, a reasonable stressdistribution could be got, that was at the beginning of deposition the suspension containingrichly BG granules was used so that a rich BG granules layer, a good transitional layerbetween BG layer at the bottom and the coating could be obtained at the titanium alloy side,the bottom of the coating; the stress value near the interface and surface and its character,pressure stress or tensile stress, were decided by the character of its composition itself.Changing composition distribution coefficient n could only change the variation tendency ofstress in the coating, but did not change the stress distribution rule in the coating. Thethinner the coating is, the sharper stress variation in the coating is, which does not mean thatthicker coating is better because the thicker the coating is, the little the permitteddeformation of coating is, so the coating thickness should be thinner, for example, about50μm for bending applications, but for applications only bearing pure shear stress, such asroot of tooth implant, the coating can be thicker little, for instance, about 80～100μm. The study on electrification characteristic and electrophoresis deposition of HAand BG granules in aqueous and non-aqueous solution system found that EPD almost didn'toccur in aqueous solution system. However, because HA granules take position charges inabsolute alcohol, a homogeneous EPD be carried out on the cathode titanium alloy slice, but taking negative charge in absolute alcohol the BG granules not be deposited on the cathode. A guided HA crystallizing, 100～300nm, on surface of the BG granules be realized by metathetical reaction, which cover BG granules with HA microcrystals and make the covered BG granules taking position charges in absolute alcohol, sequentially realize the EPCD of the BG and HA granules on the cathode, so it is feasible to make a titanium alloy/BG/HA bioactive graded coating by making use of EPCD technology. The corrosion experiment of rich boron bioglass coating and plasma spray coating showed that split phase, rich boron and rich silicon phase, occurred during its preparation. In basic medium the corrosion behavior of 〓 BG coating showed uniformity corrosion, the corrosion mostly occurred at rich boron phase area, therefore batch formula design of BGshould avoid the occurring of split phase. The corrosion appearance of plasma spray coatingappeared a non-uniform corrosion, mostly occurred at the edge of the laminated HA moltendrops, and emerged an accelerated corrosion tendency, which will easyly lead to corrosioncrackles extending to the interface and the happening of osmotic interfacial corrosion, thatmay be one of the major reasons leading to the coating cracking-off in the later period. Thetesting results of thermal expansion coefficient of 〓 and 〓BG showed the thermalexpansion coefficient of 〓 BG matched with that of titanium alloy better, and 〓 BG couldsinter with titanium alloy into densification enamel layer at low temperature (720℃).

将Ti6Al4V合金在1000℃下进行真空热处理会降低其力学性能，且合金内的V元素会向表面富集，因此，钛合金真空热处理和表面涂层的烧结温度不能过高，即应低于其相转变点；通过对生物活性梯度涂层的组成和结构的设计，分析和计算了梯度涂层内的应力大小和分布，结果表明：对于本研究，当成分分布系数n=1.5时，可以获得较合理的涂层力学性能，即在沉积开始时，采用富含BG颗粒的悬浮液，以便在钛合金侧获得同底层BG有良好过渡的富BG涂层；梯度涂层界面和表面的应力大小、性质由材料组成本身的性质决定，改变成分分布系数，只能改变涂层内应力变化的趋势；涂层的厚薄不影响涂层内的应力分布规律，但涂层越薄，涂层内的应力变化越快，但这并不意味着涂层越厚越好，因为涂层越厚，涂层允许的变形越小，对于应用于弯曲受力部位的涂层而言，涂层应薄一点为好(50μm)；而对于仅纯受剪切应力的部位，如牙根种植体，涂层可适当加厚(80～100μm)；通过对HA和BG颗粒在水溶液体系和非水溶液体系中的带电特性和电泳沉积的研究发现，它们在水溶液体系中很难发生电沉积；在无水乙醇溶液中，HA颗粒带正电，可在阴极钛合金片上发生均匀的电泳沉积，而BG颗粒则带负电荷；利用复分解反应法，可以制得100～300nm的HA，通过诱导HA在BG颗粒表面结晶，可对BG颗粒进行表面包覆，获得了被HA包覆的BG颗粒，改变了BG颗粒表面的带电特性，使BG和HA颗粒在无水乙醇中均带上正电荷，从而实现了HA和BG颗粒在阴极上的共沉积。

He bid me observe it, and I should always find , that the calamities of life were shared among the upper and lower part of mankind; but that the middle station had the fewest disasters, and was not exposed, to so many vicissitudes as the higher or lower part of mankind; nay, they were not subjected to so many distempers and uneasiness either of body or mind, as those were who, by vicious living, luxury and extravagancies on one hand, or hard labour, want of necessaries, and mean or insufficient diet on the other hand, bring distempers upon themselves by the natural consequences of their way of living; that the middle station of life was calculated for all kind of virtues and all kinds of a middle fortune; that temperance, moderation, quietness, health, society, all agreeable diversions, and all desirable pleasures, were the blessing attending the middle station of life; that this way men went silently and smoothly through the world, and comfortably out of it, not embarrassed with the labour of the hands or of the head, not sold to the life of slavery for daily bread, or harassed with perplexed circumstances, which rob the soul of peace, and the body of rest; not enraged with the passion of envy, or secret burning lust of ambition for great things; but in easy circumstances sliding gently through the world, and sensibly tasting the sweets of living, without the bitter, feeling that they are happy, and learning by every day's experience to know it more sensibly.

他嘱咐我，只要用心观察，到处都可发现：生活的灾难是由上层和下层两类人分担，而中间阶层灾难最少，不会像那两类人那样，要经历那么多的荣辱变迁，商海浮沉。中间阶层也绝不会像阔佬那样，因骄奢淫逸、挥霍无度而狂躁不安、身心俱损；也不会像穷人那样，因劳累辛苦、缺吃少穿，以及这种穷苦生活自然而然带来的种种后果而焦急不安、忧心忡忡。他说，中等生活最能保持各种美德和一切正常而适中的享受，中等人的生活经常是安定富足的。他说，和睦和富裕是中产阶层的随身伴侣。他说，和善、谦虚、宁静、健康、社交、各种正当的娱乐、各种有益的消遣，都是降临到中等人头上的福份。他们就这样默默地、但又是顺利地、当然也是舒服地走过人生的旅途，不受劳力和劳心之苦，也不必为每天的面包而卖身为奴，或被困境搞得身心疲惫；也不会因心怀嫉妒和好大喜功而野心勃勃、贪婪无度，而是在轻松的环境下平静地度过一生，有意识地品尝着生活的甜美，没有痛苦，只感到幸福，并且通过日益增多的经验，越来越有意识地去学会品尝和感受幸福。

Only with such characteristics, the movement equations can be expressed as matrices, and the idea of transforming the movement equations to the simplest form through a nonlinear transformation can be realized;(2) The form of Zi =Yi + YTH2i Y + Y7H3i Y(2)+ Y(2)T H4i Y(2)+ YTH5i Y(3) is adhibited in the nonlinear transformation, so that the multivalued problem caused by the nonlinear transformation is avoided, and the higher order transformation can be taken next;(3) The fourth order nonlinear transformation matrices H21,H31,H41 and H51 are derived, by which the original movement equations of electric power system is transformed to Jodan form in Z space;(4) By use of the fourth order nonlinear transformation, the approximate expression of the stability boundary is obtained, in Z space it is Z1= 0,in Y space it is Y1 + YTH21 Y + YTH31 Y(2)-i- Y(2) TH41 Y(2)+YTH51 Y(3)= 0;(5) The criterion used in this paper to judge whether the system critical unstable is simple and quick;(6) The method used in this paper is a direct method, and no need to construct an energy function.

正是由 于电力系统的运动方程具有这样的特性，才能写成矩阵的形式，通过非线性变换将电力系统的运动方程变换为最简单的线性形式的思想才能得以实现；（2）将通常运用于电力系统暂态稳定性分析的Normal Form变换的形式由 Yi＝ Zi＋ ZTh2riZ变形为 Zi＝ Yi＋YTH2iY＋YTH3iY（2）＋Y（2）TH4iY（2）＋YTH5iY（3），从而使得在对持续故障轨线实施同样的非线性变换以确定临界切除时间时，避免了非线性变换带来的多值性的问题，而只有在没有多值性问题的困扰下，才能采用较高阶的变换：（3）推导出了将原始电力系统系统的运动方程变换到Z空间的约当形式的非线性变换矩阵H21、H31、H41、HS1：（4）在运用四阶了「线性变换的情况下，给出了受扰动后系统的稳定边界的近似的解析表达，在Z空间为Z1=0，在y空间为： Y1+YTH21Y+YTH31Y(2)+Y(2)TH41Y(2)+YTH51Y(3)=0 （5）确定临界失稳的判据简单、快捷：对于一个复杂的电力系统，其稳定边界是相当复杂的一个高维曲面，即便是已知系统稳定边界的解析表达，要求出系统持续故障轨线何时与这一高维曲面相交，在数学上几乎是不可能实现的。

With the dose of 7.04 mC/cm2, ODT/Au will become a more strengthened structure and then form a negative resist in the correlation with cross-linking from alkyl matrix, partial breakdown of S-Au bonding and surface adsorption by air-borne species. Thus, it can obtain a gold pattern via gold-etching process. Besides, as a result of massive breakdown of alkyl matrix and S-Au bonding from ODT/Au under irradiation with doses of 64.06 and 128.13 mC/cm2, ODT SAMs would form a loose-packed structure on the gold substrate. The ODT/Au becomes less resistive for gold-etching and a positive gold pattern would form after gold-etching.

结果发现：以50 eV 低能量电子在照射剂量7.04 mC/cm2微影并曝露於大气后，受到来自於ODT/Au碳链间的交联、部分的S-Au键结破坏以及照射后立即曝露大气所吸附於表面的碳氧化物种的共同影响下，ODT SAMa於Au膜基材上将形成更紧密复杂的结构而作为负型阻剂，经后续湿式蚀刻15分钟后将显影出来Au的负型图案；当提升照射剂量至64.06及128.13 mC/cm2后，由於ODT/Au上碳链及S-Au键结的大量破坏，将使ODT/Au结构不能稳固且紧密地排列於Au膜基材上，显影时Au蚀刻液将容易穿过ODT SAMs抵达S/Au界面而移除Au，而形成正型图案。

A locomotive is designed to be almost indestructible — in this case, a 160-tonne construction of cast and welded steel. Each piece must be taken out by hand with blowtorches. The breakdown will happen from the top down in three steps.
