It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

矿石中天然固有的杂质严重影响其后来的质量。矿石的形成是地质变迁的结果，包括地壳运动，火山爆发，沉积作用，冰河作用和风化等等，在这些作用下，生成了火成岩，火山杂岩，水成岩和沉积岩等，一些矿石是由于这些作用共同形成的，这就是自然界中没有纯净矿石的原因。由于这些原因的存在，需要用分离技术和器械，也就是矿石加工设备对矿石进行的分割，迄今为止这些矿石加工设备已经不能够满足冶金工业的需要，科学家们力图用激光把冶金工业提高到一个新的水平。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

没有什么能比矿石中的杂质更能影响的矿石质量了，矿石是由包括地壳运动，火山喷发，沉积作用，冰川作用，风化作用等地质变迁形成的，在这些运动中，又形成了火成岩，火山混合物，水成岩，沉积岩等，其中还有一些岩石是以共生状态存在的，这就是为什么天然纯净矿石罕见，同时也是急需分离技术和仪器，即矿石加工装置和设备的原因，由于这些还远远未能满足冶金工业的需求，科学家们正竭尽全力试图通过激光分离将选矿技术提升到一个新的高度。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

没有什么比矿石形成之前就存在的杂质对矿石品质的影响更为重大。矿石是火成岩、火山群、水成岩、沉积岩等成形时，在包括地壳运动、火山爆发、沉积、冰蚀、风化等地质变化的作用下而形成的。而有些地质变化在一个发展阶段中存在共生现象。自然界无杂质岩石缺乏的主要原因在于需要分离技术和设备来完成，即：需要选矿设备和装置。而迄今为止，这些设备还难以适应冶金业的需要，虽然科学家们尽一切努力用激光分离技术将冶金业提高到一个新的高度。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

影响矿石质量的关键是其所含杂质的多少，其成色高低受一系列地质变迁，如地壳运动，火山爆发，沉积运动，冰川运动及风化侵蚀等作用影响，经过高温成岩，火山熔岩，含水岩，水成岩等过程形成，部分以共生态存在。自然界纯矿石稀少，因此我们需要使用分离技术和设备，即筛矿装置和器械，但目前的设备已不能满足冶矿业的需求，科学家们正试图以激光筛选使选矿技术达到一个新的水平。

"Working satisfaction can reduce absence and dimission, it also can reduce the rate of accidents."

&工作满意可以减少缺勤、离职，并可以降低事故发生率。&

Aromatic dinitro compounds were reduced irrespective of the presence or absence of β-CD in sodium hydroxide solution, which revealed particularity of aromatic dinitro compounds.These reactions have advantages below over past research results of aromatic nitro compounds:(1) The synthetic method using water as the reaction medium may

这些反应与过去人们对硝基化合物反应的研究结果相比，具有以下优点：(1)反应在水介质中进行，避免使用辅助有机溶剂和金属催化剂，是环境友好的清洁反应，比较符合绿色化学的发展要求；(2)反应中所用的β-环糊精无毒，价廉，易得
