According to existent condition, it is available to the grinding quality of the cutting tool when the grinding feed is optimized to about 10μm.

在现有条件下，当其优化为10μm左右时对刀具刃磨质量比较有利。

The experiment and the research indicate that:(1) Through the Hot-Continuous-Rolling production technics under small reduction ratio of 4.04 and 5.08, the rectangular continuous-casting billet of 235×265mm can be used to produce big size steel stick of Φ140mm and Φ 125mm whose macrostructure and mechanical properties meet the standards, this technics is viable;(2) This rolling technics can make the deformation penetrate to the center of the billet by low temperture and low velocity and big roller diameter and large reduction quantity at every pass and optimum design and arrangement of rollers, which is the key of Hot-Continuous-Rolling technics under small reduction ratio;(3) The sending technics used in Xining Special Steel Co.,Ltd can not use waste-heat of billet adequately, but the sensitive temperature section of A1N or sulphides or inclusions separating out is avoided, creating a favorablecondition for insuring good surface quality of final rolled steel;(4) The Hot-Continuous-Rolling technics under small reduction ratio has a close relationship with the billet quality control and the hot sending process control and the cooling control after rolling.

通过实验研究表明：(1) 235×265mm矩形连铸坯分别采用4.04和5.08的小压缩比热连轧生产工艺，所生产的Φ140mm和Φ125mm的大规格棒材，其低倍组织和机械性能均符合标准要求，该工艺是可行的；(2)本实验所采取的低温低速、大辊径大道次压下量轧制工艺加上轧辊孔型的优化设计与配置，可以使加工变形渗透到铸坯的中心，这一点是实现小压缩比热连轧生产工艺的关键；(3)西宁特钢在红送过程中虽然铸坯余热未能得到充分的利用，但是有效地避开了A1N、硫化物的析出及夹杂物偏析的敏感温度区，为保证最终轧材良好的表面质量创造了有利的条件；(4)小压缩比热连轧生产与铸坯质量控制，热送过程控制以及轧后冷却控制密不可分。

本方法充分运用了岩石抗拉强度低，和高压水对岩石有利渗透作用的条件，从而达到岩石裂纹的产生与扩展，直到最后劈裂。

In the National Natural Science Fund Project, supported by the Institute through 10 years in a row on the lake dried up Ebinur region of proliferation and the accumulation of observations and sampling analysis found that,Lop Nur, the Ebinur Lake, Xinjiang艾丁湖region is the main source of salt dust, from the bottom of the lake dried up Ebinur region of dust is an important source of salt dust material, Salt in the region of the frequency of dust storms has created extremely favorable conditions.

据中科院新疆生态与地理研究所吉力力阿不都外力研究员介绍，在国家自然科学基金项目支持下，该所通过连续10年对艾比湖地区干涸湖底的扩散和堆积进行观测和取样分析发现，罗布泊、艾比湖、艾丁湖地区是新疆盐尘暴的主要策源地，源自艾比湖地区干涸湖底的粉尘是重要的盐尘暴物质来源，为该地区盐尘暴的频发创造了极为有利的条件。

In the first exploration stage,several plays were divided vertically in order to show the characteristics of petroleum accumulation more clearly.With the assurance of source rock,the main play and prospect targets were chosen quickly by the assessment of reservoir,cap rock,migration passageway,seal ability of the faults,structure characteristics,favorite traps and the allied conditions.Good exploration result has been obtained in Melut Basin.

在确定油源的前提下，通过对储层、盖层、运移通道，断层封闭性、构造、有利圈闭及配套条件等方面的快速分析，迅速确定了主力成藏组合和主力成藏带，优选了勘探目标，在苏丹Melut盆地取得良好的勘探效果。

The fan delta, sand beach, sand bars and turbidite fan in the TST of SⅡ and SⅢ sequences are the most favorable exploration targets because of favorable source - reservoir - seal assemblages. Since the high - stand system tract in SⅡ sequence has good source - reservoir assemblage and is covered by the regional seal of SⅢ sequence, the hydrocarbon accumulation in this area is controlled by the local seal rock. The HST of SⅡ sequence becomes the second favorable exploration target zone. Because the scales of the sand bodies of alluvial fan and braided river in low - stand system tract of SⅡ and SⅢ sequences are limited, the formation of a large hydrocarbon accumulation is difficult.

良好的生储盖配置使SⅡ层序、SⅢ层序水进体系域的扇三角洲、滩坝及浊积扇砂体成为本区最佳勘探目标层。SⅡ层序高位体系域生储条件配置好，又有SⅢ层序区域盖层的整体封盖，油气聚集受局部盖层直接控制，可成为较有利的勘探目的层。SⅡ层序、SⅢ层序低位体系域的冲积扇、辫状河砂体体积规模较小，难以形成大油气藏。

In my opinion, it is beneficial for us to attend English classes provided that the teachers are qualified.

在老师合格条件下，以我所见，上英语课我们是有利的。

At present, laser process technology develops fast, since a laser light can obtain many good characteristics such as good direction, high energy density to focus the beam at a micrometer level, small pulse width ranging from dozens of Nanoseconds to dozens of Picoseconds, heating material immediately, decreasing heat effect on materials and so on.

由于激光束具有良好的方向性和高能量密度，可将光束聚焦到微米量级；由于激光束的脉冲宽度可达数十纳秒到数十皮秒，能够快速加热，对材料的热影响效应减小；因此，激光的以上优点为微加工提供了有利的条件，同时也促使激光加工技术迅速发展。

As the flag state relaxed to facilitate the naturalization conditions, coupled with their administrative, technical and social matters almost not control flag of convenience vessels, which reduces the ship's operating costs, so that owners be able to escape the obligations of the relevant international treaties so that they competition in international shipping, in a good position, which has been welcomed by national shipowners, have put their flag state vessels to facilitate naturalization.

由于方便船籍国宽松的入籍条件，加上它们在行政、技术及社会事务上几乎不对方便旗船进行管制，这降低了船舶的营运成本，使船东得以逃避有关国际条约的义务，使他们在国际航运的竞争中处于有利地位，因而受到了各国船东的欢迎，纷纷把他们的船舶入籍方便船籍国。
