A basic fact about sets is that there are two sets only when their memberships differ. The membership of the set of things that are phlogiston is exactly the same as the membership of the set of things that are Devil-dealing Salem witches. In each case, there are none. So in each case the set of instances is the set with no members, the null set.

按集合观，不承认这里有不同的共相，因为基础事实是，两个集合不同当且仅当成员不同，而这两个集合是相同的，因为都是没有成员的集合，即空集。

Its main features were: the flowering branch 70~170 cm; the inflorescence is racemes or simple panicle; the axis of inflorescence is thick, and the node is distict; there are 4~5 florets in a spikelet, and the spikelet is non-stem; small rachis internodes glabrous, and the pikelet like a stick; there are 2 membrane glume; the lemma is longer or equal to the palea; there are 2 squamas, and 6 stamens; its ovarium like ovatum; there are 3 brushy tigmas; did not see the caryopsis; flowering February-March.

The finite element models of two types of machine guns are set up, mainly based on the 3-dimensional beam elements, partly based on boundary elements. Modal experiment plan of the machine guns is designed and their modal analysis experiments are done. The inherent properties of structural vibration and dynamic response properties for type-02 14.5 mm anti-aircraft machine gun and type-89 12.7mm machine guns are completely realized through the method combining theory and experiment, and many valuable conclusions are obtained.

建立了以三维梁单元为主，边界元为辅的高射机枪和重机枪有限元模型，设计了模态试验方案并进行了两支枪的试验模态分析，采用理论与实验相结合的分析方法，全面揭示了 02 式 14.5mm 单管高射机枪和 89 式 12.7mm 重机枪的结构振动固有特性和动力响应特性，获得了许多有价值的结论。

Firstly, urban space's development course and actuality of space's patterns are reviewed contrastly in the paper abroad and home. Then, existing problems of urban space at present in our country are discussed stressly:"Ten Faulty Expressions in Writing" of urban construction;"the Movement of Beautifying City" in china; the problem of urban characteristic; the problem of reforming of old city; the problem of residential segregation. The above problems' formed reasons and countermeasures are put forward. Then, the example of Xi'an and its existing problems of urban space and several countermeasures are analyzed in the paper. The transformation of three sections realized in the planning thought of urban space is put forward: from "elitism" to "plebeianism"; from mega-urban project design to "daily living space" and from "technology first" to "human-oriented".

论文首先从中西方城市空间形态的演变历程入手，对比分析了国内外的空间形态现状，重点论述了当前我国存在的城市空间问题：城市建设"十大败笔"；中国"城市美化"运动；城市特色问题；旧城改造问题以及空间分异问题，分析了其形成原因并得出了解决途径，然后对西安进行了实例分析，总结出其城市空间存在问题并提出几点对策，接下来提出了城市空间规划理念应实现的三个方向的转变：从"精英主义"向"平民主义"理念转变、从大尺度城市设计向"日常生活空间"营造转变以及从"技术至上"向"以人为本"理念转变。

On the basis of a study and elaboration of data, some important conclusions are presented:(1) ruby deposits in marbles occur in the plutonic metamorphic zones of orogens where deep fault structure is developed;(2) ruby-bearing rocks are calcic crystalline marbles, rather than magnesian marbles;(3) amphiboles in ruby-bearing rocks are not tremolites, but silica-poor, alumina-rich and chrome-bearing calcic amphiboles, such as chrome-bearing magnesio-sadanagaites; and (4) the deposits are genetically of thermodynamical metamorphism type, rather than of pneumatolito-hydrothermal type or skarn type.

目前，对于与此类型矿床找矿相关的若干成因问题的认识，还相当模糊，主要表现在以下几方面：①对此类型矿床的产出构造背景认识不清；②认为含矿岩石为镁质大理岩或镁质夕卡岩；③认为含矿岩石中与红宝石共生的角闪石为透闪石；④认为此类矿床的成因类型为"气成一热液型"或"夕卡岩型"。本文在实际研究(王礼胜，1996)和文献资料整理的基础上，分别对这些问题给予了澄

Secondly, two methods are combined into a 2D classifying method and again the current highway information foundation data elements are classified in 2 Dimensions. The problems in data element set are pointed out and also the expand idea is put forward. The key properties of 2D classifying data element are studied.

将2种分类方法结合形成二维数据元分类方法，并对现有公路信息基础数据元重新进行了分类，指出存在问题并给出了数据元扩充的思路，对二维数据元的关键属性进行了研究。

Chen your appointment as factories on the Chinese side. and the POLA and LUIGI you then sent from Italy to help your management, However, their management is very problematic, as a manager, do not say anything, personal qualities are most important, do not know how to respect other people who are not qualified to be respected, they treat people too hypocritical. I think people are no boundaries between class hours, which of them is right, but they are right staff attitude serious harm to us, Ironically apt to have spoken to the people to speak, the people do not like them regardless of whether those individuals will have arbitrarily denied it, exclusion or expulsion.

小陈是您聘用做为工厂的中方代表，而POLA和LUIGI是您从意大利那派来协助您的管理，可是他们的管理实在是很有问题，身为一个管理员，其他什么都不说，个人素质是最为重要的，不懂得尊重别人的人是不配被人尊重的，他们对待人太虚伪了，我想人与人相处是没有国界阶级之分的才对，但是他们对员工的态度严重的伤害了我们，动不动就以讽刺的口吻跟人说话，不喜欢的人他们就不管那个人能力的好坏就随便否认，排斥甚至开除。

My baby is so big, but fat, body weight reached 25 kg, I am just up to him when the points are generally water, nine did not feed him milk thick of things which are 10:00 after eating sweet potato polenta Add Shrimp Powder, liver powder, what, or add vegetables, foam, and then between infants, probably around 56 when the complementary eat, eat anything, vegetables Mo肉沫, ah fish, shrimp ah, what eat, huh, huh, what has to eat what ah rice, congee for what to do with kind of a custard or steamed, and thus we can regulate appetite, but remember the baby things eating meat immediately after the Do not let him sleep , one will let him play, or one will be running walker, digestion digestion to avoid eating "bad" after on the do not eat, and sometimes also added three complementary, morning and afternoon hours to find fruit, are generally 1 hours after a meal to make him have to add fruit, a variety of eat, huh, huh, including what kind of tomatoes cucumber, bite him immobile grinder can be used to give him a crumble or juice pressed out, I also each days in milk to give him increase in one or two probiotics, and I gave him all熬粥with thickness, and a variety of coarse grains of pulses are for Endure, my baby is now very robust, does not make the basic problems also bless your baby healthy and happy!

我的孩子也是这么大，不过很胖，体重达到了25斤，我早上刚起来的时候一般都是给他点水喝，九点以前不喂他稠的东西都是喝奶，都是十点以后才吃红薯玉米粥加虾粉，肝粉什么的，或者加蔬菜沫，然后中间吃奶，大概五六点左右的时候再吃辅食，什么都吃，蔬菜沫肉沫，鱼啊，虾啊，什么都吃，呵呵有什么吃什么，米粉啊，粥什么的换着样的做或者蒸个蛋羹，这样也调节食欲，但是记住了孩子吃完肉类的东西后别让他马上睡觉，要让他玩一会，或者用学步车跑一会，消化消化免得吃"坏"了以后就不吃了，有的时候也加三次辅食，上午和下午找时间加水果，一般都在饭后一小时做有给他添加水果，各种各样的都吃，呵呵包括黄瓜西红柿什么的，他咬不动的可以用研磨器给他弄碎了或把汁榨出来，另外我每天都在牛奶里给他加一到两次益生菌，而且，我给他熬粥都是粗细搭配的，各种粗粮豆类都换着熬，我的孩子现在很健壮，基本不闹毛病，也祝福你的孩子健康快乐！

It is found that there is a mineral association, micro-crystal muscovite and phengite, in this deposit. The mineral assemblage contains about 80% micro-crystal muscovite and about 20% phengite. Their crystallinity is very high and their polytype is 2M1. Both of them are dioctahedral because the d and b of micro-crystal muscovite and phengite are 0.1502 nm, 0.9012 nm and 0.1505 nm, 0.9030 nm, respectively. For their d and b are larger than those of common muscovite, the reason why Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+) are high in the ore is that Al(superscript 3+) in the octahedron is replaced by Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+), and this is a phengite series mineral association formed through isomorphic replacement.

该矿物组合中的微晶白云母和多硅白云母结晶度高，多型为2M1，其含量分别为80%和20%左右；二者都属二八面体型白云母类矿物，但d060和b值偏大，微晶白云母的d060=0.1502nm，b=0.9012nm，多硅白云母的d060=0.1505nm，b=0.9030nm；微晶白云母矿铝含量较低、铁镁含量较高，其原因是白云母晶体铝氧八面体中的Al离子被Fe、Mg等离子所取代，这一矿物组合是通过矿物类质同象作用所形成一种多硅白云母系列矿物。

Again some tw*ty immigrants are exactly like what you described--illegal this and illegal that--these people are the ones who give us a bad name...you can't say these things are "what we are actually doing behind the door"--that is called "prejudgement" which i think it might spells as "prejudgment" spot the difference!

我的 comments可能有点过于讽刺，但是没有恶意， lkcn有权说他/她要说的，为什么我不可以？何况我没有讲错，是那些不正当的immigrants给了大部分良民 bad names。。。但是他/她不应该将所有的immigrants归类为不法份子。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
