This paper attempts to explain floatability classification parameters of coals through the theoretical data of float and sink in comparison with flotation efficiency.

本文嘗試利用煤在重液中分離所得的理論指標與煤的浮選效率的比較關係來探討煤的浮選性分類指標。

By discussing the basic hypotheses about the continuous orbit and discrete orbit in two research directions of the background medium theory for celestial body motion, the concrete equation forms and their summary of the theoretic frame of celestial body motion are introduced. Future more, by discussing the general form of Binet's equation of celestial body motion orbit and it's solution of the advance of the perihelion of planets, the relations and differences between the continuous orbit theory and Newton's gravitation theory and Einstein's general relativity are given. And by discussing the fractional-dimension expanded equation for the celestial body motion orbits, the concrete equations and the prophesy data of discrete orbit or stable orbits of celestial bodies which included the planets in the Solar system, satellites in the Uranian system, satellites in the Earth system and satellites obtaining the Moon obtaining from discrete orbit theory are given too.

在深入研究引力理論及廣義相對論的基礎上，通過討論天體運行背景介質理論的連續軌道及離散軌道這二個研究方向的基礎假設，介紹了天體運行軌道的具體方程形式及理論框架概要；進一步地通過討論天體運行軌道Binet方程的一般形式及其行星近日點進動角的解，給出了連續軌道理論與Newton理論及Einstein廣義相對論的聯繫與區別；通過討論天體運行軌道的分維擴展方程，給出了包括太陽系行星、天王星衛星、地球衛星、繞月航天器等在內的離散軌道方程及其預言資料。

NF 77 is a light duty cutting oil for all general operations of non-ferrous metals including cuprous metals, aluminium and their alloys. NF 77 contains special lubricity fortifiers to impart quick release of chip from tool. The low viscosity ensures the good cooling and flushing properties, which are essential for high speed machining.

NF 77 是一款專為非鐵金屬而配製的切削油，適用於銅金屬、鋁金屬及其合金的一般輕度切削，含有特殊潤滑添加劑，使屑片容易與刀具分離，低的黏度確保了足夠的冷卻及沖屑性能，都是高速切削所必需。

NF 99 is a heavy duty cutting oil for all general operations of non-ferrous metals including cuprous metals, aluminium and their alloys. NF 99 contains chlorinated additives, fatty oil and special lubricity fortifiers to impart quick release of chip from tool even under extreme high cutting pressure. The low viscosity ensures good cooling and flushing properties, which are essential for high speed machining.

NF 99是一款專為非鐵金屬而配製的切削油，適用於銅金屬、鋁金屬及其合金的重負荷切削，含有氯化物、脂肪及特殊潤滑添加劑，增進其極壓及潤滑性能，就算在高切削壓力下，也能使屑片容易與刀具分離，低的黏度確保了足夠的冷卻及沖屑性能，都是高速切削所必需。

Guatemala：地马拉

地帶,橫跨瓜地馬拉(Guatemala)、貝利斯、墨西哥(Mexico)、宏都拉斯(Honduras)和薩爾瓦多(El Salvador)部份地區,分別以三個互相隔 離的區域為中心──齊阿巴斯和瓜地馬拉高原的南部高地、太平洋潮濕的沿海平原與薩爾瓦多西部、墨西哥灣伸展到貝利斯一帶及宏都拉斯的熱帶森林區.
