位置精度对发动机寿命的影响

发动机多采用换件工艺进行大修,即将主要运动件大部或全部换为新件,而且多为标准件。经大修后的发动机,其工作寿命大约仅为新产发动机的一年,这并不是被换上的新件的精度,而是基础件的变形所造成的位置经度降低所引起的。通过试验研究探索位置精度对工作寿命的影响,找出其规律以及可采取的措施。     

Richard Lewontin and the “complications of linkage”

During the 1960s and 1970s population geneticists pushed beyond models of single genes to grapple with the effect on evolution of multiple genes associated by linkage. The resulting models of multiple interacting loci suggested that blocks of genes, maybe even entire chromosomes or the genome itself, should be treated as a unit. In this context, Richard Lewontin wrote his famous 1974 book The Genetic Basis of Evolutionary Change, which concludes with an argument for considering the entire genome as the unit of selection as a result of linkage. Why did Lewontin and others devote so much intellectual energy to the “complications of linkage” in the 1960s and 1970s? We argue that this attention to linkage should be understood in the context of research on chromosomal inversions and co-adapted gene complexes that occupied mid-century evolutionary genetics. For Lewontin, the complications of linkage were an extension of this chromosomal focus expressed in the new language of models for linkage disequilibrium.

What's nu? A re-examination of Maxwell's ‘ratio-of-units’ argument,from the mechanical theory of the electromagnetic field to ‘On the elementary relations between electrical measurements’

This re-examination of the earliest version of Maxwell's most important argument for the electromagnetic theory of light—the equality between the speed of wave propagation in the electromagnetic ether and the ratio of electrostatic to electromagnetic measures of electrical quantity—establishes unforeseen connections between Maxwell's theoretical electrical metrology and his mechanical theory of the electromagnetic field. Electrical metrology was not neutral with respect to field-theoretic versus action-at-a-distance conceptions of electro-magnetic interaction. Mutual accommodation between these conceptions was reached by Maxwell on the British Association for the Advancement of Science (BAAS) Committee on Electrical Standards by exploiting the measurement of the medium parameters—electric inductive capacity and magnetic permeability—on an arbitrary scale. While he always worked within this constraint in developing the ‘ratio-of-units’ argument mathematically, I maintain that Maxwell came to conceive of the ratio ‘as a velocity’ by treating the medium parameters as physical quantities that could be measured absolutely, which was only possible via the correspondences between electrical and mechanical quantities established in the mechanical theory. I thereby correct two closely-related misconceptions of the ratio-of-units argument—the counterintuitive but widespread notion that the ratio is naturally a speed, and the supposition that Maxwell either inferred or proved this from its dimensional formula.

狭义相对论不变性初探

狭义相对论声称（一切）“自然定律对于洛仑兹变换具有形式不变性（或协变性）”。但是，本文的审查得出的结论是：（１）作为洛仑兹变换直接推论的尺缩钟慢说本身就自相矛盾，是混淆了感觉与存在，表现效应与（内在的）物理效应的产物；（２）关于光速不变原理的“验证依据”都是不足为据的，因为有关它们的论证都违背了洛仑兹变换的导出前提，特别是直接违反了光速不变性；（３）洛仑兹变换的推导有严重错误，它是在错误的前提下通过错误的推导得出的错误结果；因此──—“皮之不存毛将焉附”，“自然定律对于洛仑兹变换具有形式不变性（或协变性）”是不成立的。此外，文中还讨论了著名的“质速关系”，揭示了它的真相。     

相对绝对论

仅根据光速不变原理就可严格地导出允许绝对静止系存在的坐标变换,这种新变换的成立决定了以光速不变为前提之一可以得到“爱因斯坦Ｅｉｎｓｔｅｉｎ相对论”、“固有时间与空间无关的相对论”和“相对绝对论”三种理论,本文通过比较上述三咎理论发现只有相对绝对论才是自给的。
