本論文的目的是確定中國新石器時代至青銅時代大型玉料開料片切割技術。玉是一種堅硬的石頭，在礦物學上只有軟玉和硬玉才是真正的玉。其他所有看似玉的珍貴石料由於包含不同的化學成分，故此只能被稱為美石。玉石工藝源於石器製作技術，當中包括打製和磨製技術。本論文集中於研究摩擦技術。片切割的運作是通過摩擦作用從而磨掉玉料的一部分。玉器上的三個常見的切割技術包含片切割，柔性線切割和旋轉切割（陀切割和鑽孔）。這些技術都應用在玉石和珍貴的美石 。中國考古出土大量的大型長薄片狀的玉器和珍貴的美石製品。這些成品，半成品和廢品都開展示出證據不同的切割技術的表現。然而，如何進行大型開料的片鋸切技術至今仍然沒有具系統性的說法。考古學家和科學家們都各自提出了不同的見解。 本文通過實驗考古片切割大型蛇紋石以及其他切割實驗比較與文獻研究，探討不同種類的切割技術。實驗結果與考古出土文物會進行比較和分析。此外，解玉砂和水在鋸切過程中發揮著重要的作用。提高工件的切割的效率，而水同時發揮降溫作用看到，以防止由不斷摩擦產生的過熱引起破損。這項研究還包括研究選定的帶有片切割跡的三星堆玉器標本。這些文物提供了一個很好的線索來比較從實驗考古所產生的切割痕跡。 / The purpose of this thesis is to determine how large-scale blade sawing on jade was performed during the Neolithic Period till the Bronze Age in China. Jade is an ornamental hard stone that specifically applied to nephrite and jadeite, the metamorphic rocks. Those look-a-like jade and other gemstones can only be called precious hard stones due to their different chemical components. Jade work originated from flint knapping techniques, which included percussion and rubbing of the lithic technology. This research concentrates particularly rubbing techniques. Blade sawing is an abrasive motion that through rubbing (polishing) which leads to part of workpiece being worn away. The three common sawing techniques on jade are blade cutting, string cutting and rotary cutting (wheel cutting and drilling). These techniques are applied to both jade and precious hard stones. The Chinese archaeological field works unearthed numerous of large-long-flat-thin shaped jade and precious hard stone artifacts. These finished artifacts, semi-finished items and debitages indicate the strong evidence of different sawing technique performances. However, how blade-sawing technique was performed still uncertain. Archaeologists and scientists suggested different methods. In order to examine large scale-blade sawing technique, this thesis through experimental archaeology on sawing serpentine to simulate the operation of large scale blade sawing along with literature review of other sawing experiments. Experiment results along with the archaeological context and distribution of artifacts are analyzed. Furthermore, sand, an abrasive agent, and water play important roles in the sawing process. Abrasives increase the effectiveness of sawing on workpiece, while water cool down the saw itself to prevent breakage caused by over heat from continuous rubbing. This research also includes studying the selected specimens from Sanxingdui Site with blade sawing evidence. These artifacts provide a good clue to compare the cut marks from the experimental object. / Detailed summary in vernacular field only. / Cheung, Yu Ling. / Thesis (M.Phil.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 96-103). / Electronic reproduction.

We have used the optical polarization properties of BL Lacertae objects to gain insights into the range and physical causes of their extreme and spectacular observed properties. This dissertation consists of three parts. In Part I we provide an introduction to BL Lacs and other active galactic nuclei. In Part II we present the result of an extensive monitoring program of the optical polarization of x-ray selected BL Lacs (XSBLs). In Part III we present the results of the most extensive optical polarization survey so far undertaken. Our study of the optical polarization properties of XSBLs confirms that the BL Lac candidates found in x-ray surveys like the Einstein Extended Medium Sensitivity Survey meet the requirements for membership in the class of BL Lacs. In addition to having featureless optical spectra, the majority of the XSBLs are also variable in their flux output and have intrinsic and variable polarized emission. Although x-ray selected BL Lac candidates have proven to be BL Lacs, the characteristics of their optical polarized emission are different from those of the classical radio selected BL Lacs. The XSBLs have lower maximum percent polarizations, a lower duty cycle, smaller variations in flux, and a greater tendency to have preferred angles of polarization than radio selected BL Lacs (RSBLs). We discuss the consequences of these differences and their consistency with the "beaming" model first proposed by Blandford and Rees (1978). Our optical polarization survey is the most extensive survey of its kind ever undertaken. The survey is complete to a B magnitude of 20 and covers 560 square degrees. Our sensitivity to polarized objects is a function of survey field. We did not find any confirmed BL Lacs or highly polarized quasars, but we are able to constrain the surface density of the various populations of polarized objects. For example we are able to rule out at the 90.0% confidence level the presence of a population of radio quiet BL Lacs or highly polarized quasars (with optical flux and polarization properties similar to radio selected BL Lacs) that would have a cumulative surface density of 0.03 per square degree down to a B magnitude of 20.
