Emeralds are also cut in many other , mainly classical shapes , but if the raw material contains a large number of inclusions , it may often be cut into a gently rounded cabochon , or into one of the emerald beads which are so popular in india 祖母绿也可切割成不同的型，主要是传统的造型，而瑕疵较多的宝石往往是被切割成半圆弧面型
The system , with a centralized heating design , has a wide range of applications , both for manufacturing of small volume but multiple shapes of packing products and large volume production of a single product 采用了多面型集中干燥系统的设计方案，产品适应性广，既可以适合多品种小批量的工业产品包装材料生产，又可以适应单个品种的大批量生产。
Based ongeological condition and mechanics propertie s of open - pit footwall slope rock in xinqiaopyrite mine , the stopes stability is analysed by calculation of double slide face typefailure mode with limit equ ilibrium theory 基于对新桥矿露采下盘边坡的地质概况和岩石物理力学性质分析，采用极限平衡理论，通过双滑面型破坏模式的计算，对边坡作了稳定性分析。
There are intensive structural and magmatic hydrothermal movement with obvious zonal surface shape alterations , which are demonstrated by silicified function , sericitization , potassium , epidotization , hornstone , etc . the ore structural fabric mainly behaves in form of filling action with minerals such as pyrite , chalcopyrite , salenite , blende and electrum , which typomorphic feature shows a hypothermal pattern of metallogeny 呈面型蚀变，分带特征明显。矿区内矿体规模巨大，矿石组构主要为以充填交代作用为主，矿石矿物主要为黄铁矿、黄铜矿、闪锌矿、方铅矿和银金矿。而且矿物的标型特征显示了低温成矿的特点。
Absolute distribution of laser beam intensity is gotten from comparative distribution . the absorption coefficient of material is calculated by measuring transmissive ratio . the influences on temperature increment , stress and phase of laser beam are computed with different time , window cooling , window rotating , shape and material of window , distribution of intensity 由近场光斑相对分布得到其绝对分布，测量窗口透过率，求得材料的吸收系数，在此基础上计算了出光时间长短、窗口有无冷却、是否旋转、窗口材料及面型、光强分布形式对窗口温升、应力和光束位相的影响。
Therefore , it is necessary for guaranteeing the quality of steel plate to detect and repair the roll profile timely and exactly . this paper presents the sonic circulation and multi - pulse echo principle and designs roll profile ultrasonic measurement system based on the analysis of 3d surface measurement technology and roll profile measurement methods 本文在分析了三维面型检测的发展现状及目前辊型的检测方法的基础上，提出了声循环多次脉冲反射测量原理，并以此为基础设计了上位机化的超声波辊型测量系统。
Abstract : because the shenfu - dongsheng mine area is located in intermediate of arid and semiarid zone , its ecological environment is very fragile . based on the fragileeco - environmental , the coal mining and construction have brought out some new environmental problems . man - made debris flow problems is the most serious of them which caused by coal mining , construction of railway and highway as wellas exploiting stone . through a great deal of experiments of artificial simulation setting water rushing to two types of slope debris flow and debris flow gully in shenfu - dongsheng mine site , the characteristics is favourable to formation of debris flow ; ( 2 ) the waste gangue is easy to initiate and is main solid material of debris flow in this area ; ( 3 ) the whole debris flow process could be observed through the model simulation experiment of debris flow gully . at present , this experiment method is the best way to analyze debris flow genesis and process 文摘:神府东胜矿区位于黄土高原北部干旱半干旱过度地带,由于煤田的大量开采,诱发了大量的环境问题,尤以人为泥石流最为严重.本文以神府-东胜矿区人为泥石流为研究对象,采用人工放水冲刷模拟实验的方法,分析了坡面型和沟谷型泥石流源地松散体起动、产沙、泥石流过程的特性,所得结论为: （ 1 ）放水历时长、强度大,有利于泥石流的形成; （ 2 ）弃土石渣易起动,是该区泥石流固体物质的主体; （ 3 ）沟道型泥石流放水冲刷模拟实验,便于观测泥石流的全过程,坡面型泥石流放水冲刷模拟实验,利于统计产沙、观测侵蚀形态
