He has theconsciousness of the death innerly, the childhood girlfriend's deathmade Humbert think the death uniquely;the death is unique to him, Lolita is the "time" for him. the death to him is not dread anymore and itchanges into metaphysical power;he heads for the death with the relationto Lolita, because in the relation he clearly feels that the being'sabsurd and brutal, he inevitably loses the past and the future ,so thedeath is not only the release but also the surpass for Humbert.To Lolita , she finally loses her meaning when trying to use thetime. The trip to the death is the certain result for her looking downon the rule of the time;she is most interested in the future;but herexperience with Humbert in fact have killed her who should be morevigorous, she just dies on the "now" time;and it also snatches herfuture, so Lolita is just from one nothingness-condition to another;Lolita can not grow in the right meaning and her life is not full enoughbecause she can not use the time rightly. Lolita costs too much for herlife just because she bantered the time and wanted to use the time toexceed all the control.So finally, the two people's fate is the death, with the time's pushing forward.

For the tracking system, the means that can intellectively assist the fault diagnosis and maintenance is significant. Then we can avoid relying heavily on the experiences of the engineers and can reduce the probability of the event that engineers climb up to the antenna with heavy instruments when the faults turn out. For the data channel, to get the high-qualified remote sensing images, we need to get the quantitative data about how the factors influence the BER of Receiver .The data can help the design of receiver and the evaluation of the performance of a receiver.

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。

The Lynn White debate, which begun when White called for a rethinking of Christianity or its replacement by a nonWestern religion, has proved an obstacle to dealing with the environmental crisis The defense of Christianity that followed inhibited Asian and comparative environmental ethics in the West and did not produce environmentally useful results Whenever the relationship of religion and the environment was raised, the discussion quickly shifted to the issue of Christian responsibility for the environmental crisis The problem with the debate is that in many important ways, the White thesis is correct: Christianity is indeed responsible to a significant degree in that Christianity desacralized nature and it supported policies politically in the Middle Ages that encouraged now harmful human population growth and promoted science and technology, much of which has proved to be environmentally problematic There was nevertheless a second tradition of which Saint Francis of Assisi was a part that was environmentally friendly and that could be useful in rethinking Christianity environmentally It is however unlikely that Christianity will prove useful in the development of an environmental ethic in nonWestern countries or that nonWestern religions will succeed in producing an environmental ethic in the West It is therefore important that religious scholars move beyond assigning blame for the environmental crisis and find ways for the major world religions to help develop environmental ethics as best they can within their own cultural spheres
林恩怀特争论始于怀特关于对基督教进行重新思考或者由非西方宗教取而代之的呼吁。林恩怀特争论已经被证明成为处理环境危机的一个障碍。由此而起的对基督教的辩护制约了亚洲和其他比较环境伦理学在西方的发展,没有产生对环境有益的结果。无论何时,当人们谈及宗教和环境的关系的时候,讨论都会迅速转向有关基督教对环境危机责任的讨论。这一争论的关键在于,怀特的论文在很多方面是对的:基督教的确在相当大的程度上造成了自然的世俗化,并且在中世纪,基督教在政治上对现在看来有害的人口增长的政策提供了支持,促进了科学和技术的发展,很多诸如此类的政策已经被证明对环境是有害的。但是,基督教还存在另一种对环境友好的传统,Assisi城的&圣芳济&运动就是其中一例,这种传统也许对于从环境角度重新认识基督教是有益的。但是,对于非西方国家环境伦理的发展,基督教将很难能够有所作为,非西方宗教也不大可能成功地在西方产生出某种环境伦理。因此,对于研究宗教的学者们而言,重要的是要走出谁应该为环境危机受到指责的争论,找到世界各主要宗教如何在其各自的文化范围内对发展环境伦理提供最佳帮助的方法。
