对湘南锡矿形成的地质背景和找矿方向进行研究，不仅能解决锡矿找矿中存在的许多重要的科学问题，为进一步寻找锡矿资源指出方向，而且对认识湘南地区地质构造演化史、探讨花岗岩类及其锡矿床的形成环境也具有特别重要的意义。

Quartz - vein type and greisen - type associated with tungsten, and porphyry - type are major types of Sn deposits, In recent few years, a new type of tin deposit- clastic altered rock type has been discovered, which made new development in tin - probing.

赣南地区是闻名于世界的钨锡矿产区，区内锡矿主要有与钨矿共生的石英脉型、云英岩型，斑岩型，隐爆层间裂隙带型等类型，近年来，又发现了锡矿新类型——破碎蚀变岩型，使本区找锡又有了新的进展。

The Maoping tungsten-tin deposit is located in the eastern section of Nanling metallogenic belt, the Chongyi-Dayu-Shangyou tungsten polymetallic ore concentration area and at the front part of the Tianmenshan rock mass extension with a north trend. Greisen and the quartz vein are the main tungsten-tin mineralization types in the mine area.

茅坪钨锡矿床位于南岭成矿带东段，位于崇－余－犹钨多金属矿矿集区西华山－杨眉寺区段中北部的天门山－红桃岭矿田，为天门山岩体向北倾伏延伸的前锋部位；矿区钨锡矿化类型主要有云英岩型和石英脉型两种。

L the normal zonning in order of greisen type tin deposit 〓tourmalite type tin deposit 〓 cassiterite quartz type tin deposit 〓cassiterite sulfide tin deposit copper-lead-zinc 〓 sulfide deposit 〓lead-zinc sulfide deposit 〓antimony deposit, which may be related to the high-level em placement of the intrusions;2 the reversed zoning in order of lead-zinc deposit 〓copper-lead-zinc deposit 〓tin polymetallic deposit, which may be result from the descending of heat centre of the intrusions with their cold and solidification.

该成矿系列的矿床在空间上有序分带，即以岩体为中心的顺向分带为：云英岩型锡矿床〓电英岩型锡矿床〓锡石石英型锡矿床〓锡石硫化物型锡矿床〓铜铅锌金属硫化物矿床〓铅锌硫化物矿床〓锑矿床，逆向分带为：锡多金属矿床〓铜铅锌硫化物矿床〓铅锌硫化物矿床，造成这种分带现象的内在因素是高热能且富含矿热液的黑云母花岗岩的高侵定位和岩体热中心的向下移动。

The technological flow for directly preparing sodium stannate from the low grade tin ore (containing tin 20%￣30%) has been studied.

研究了用低品位锡矿（含锡20％～30％）直接制取锡酸钠的工艺流程，即把锡矿先进行还原焙烧，然后用NaOH溶液浸出，最后把溶液浓缩结晶制成锡酸钠产品。

Through study on the typochemical composition and the association features of typomorphic minerals of stannite, silver-bearing stannite, hocartite and canfieldite, this paper provides some information for this deposit's geneses, deep blind silver mineralization and prospecting in this mine and its vicinity.

文章通过广西凤凰山银锰矿床中S－Fe－Cu－Ag－Sn系列矿物黄锡矿、含银黄锡矿、银黄锡矿、硫银锡矿的化学成分标型、标型矿物组合特征的研究，为该矿床的成因、深部隐伏银矿化、矿区及其外围的找矿提供了一定的信息。

Tin-bearing minerals in the Dajing tin-polymetallic deposit are cassiterite and stannite.

大井锡多金属矿床含锡矿物为锡石和黄锡矿，产于3个成矿阶段和5种矿石类型中。

To 2412Ma. but also certificates the multicycle and inheritance of tin mineralization in the region; moreover, it provides an instance for marine exhalative tin mineralization associated with mafic magmatic activity.

此举不仅将我国锡矿成矿时代从800Ma左右推前至2412Ma左右，而且证明了该区锡矿化的多旋回性和继承性，也提出了一个与镁铁质岩浆活动有关的热卤水锡矿化的实例。

Economic globalization has expanded the international community to use the scope and tin resources, intensified the world's tin ore resources for the countries in the world a better understanding of tin ore resources to the important position and role.

有高手帮我翻译一下我的论文摘要，无限感激！谢谢摘要：经济全球化扩大了国际社会利用锡资源的范围和方式，同时加剧了世界对锡矿资源的争夺，世界各国进一步认识到了锡矿资源的重要地位和作用。

Historically, Sungai Lembing was a rich and famous town, as the main producer of tin in Pahang.

锡矿博物馆－林明镇是个很富有和著名的市镇，因为它是彭亨州的主要锡矿生产区。

No clear conclusions can be made about the predictie alidity of specific measures, they found, except for criteria for the underuse of drugs for cardioascular disease.

除了心血管病不合理用药标准外，对于特定评价方法的预测效度没有明确的结论。

The third and last is that almost all of them, being infinite in number, have been impostures, and by idle and crafty brains merely contrived and feigned after the event past.

第三、即最后一点是：几乎所有这些不胜枚举的预言都是欺人之谈，都是在事件过后由无聊而狡猾的脑筋推测与凭空捏造的。
