A large range of IRZ and intense fluctuating velocity area around the boundary of IRZ is measured and thought to be important to keep the excellent ignition and combustion characters of the new kind swirl burner. Together with temperature trace method, different structure and operation parameter of the burner are studied in this paper about their effects on turbulent and mixing characters of swirling jet. The structure variation includes different blade angle, use of central gear shape baffle, variable outer length and angle of lean primary air outlet, use of wedge outlet of lean primary air.

采用上述两种测量方法并结合热质比拟温度示踪的方法，本文对径向浓淡旋流煤粉燃烧器喷口结构和气流流动参数的变化对旋流流场的流动、混合、湍流脉动特性的影响进行了深入研究，研究了旋流叶片倾角大小、中心齿型扩锥、淡一次风扩口外伸长度和扩角的变化、淡一次风楔形扩口、直流二次风扩口角度的变化对出口旋转射流流动特性的影响，研究了一次风率和旋流二次风率运行参数变化的影响规律。

Some conclusions are followed:(1)the reaction ratio of boron is 12% in primary combustion;(2)the degree of agglomeration can be decreased adopting boron coated with AP;(3)the content of oxygen is very important for afterburning efficiency;(4)the afterburning efficiency will be changed with different air-gas ratio;(5)the head distance of after-burning chamber is increasing, the circumfluence in the head of after-burning chamber is stronger and the distribution of fuel backward the after-burning chamber is more well-proportioned.(6)the combustion efficiency of DR will be improved by increasing the area of fuel nozzle.(7)the angle between dual air-inlets have complex influence with the combustion of DR.

通过本项研究，取得如下结论：（1）一次燃烧硼反应比例在12～15％之间；（2）AP包覆硼，可以降低硼结团度，有利于一次燃烧喷射效率的提高，也有利于硼在补燃室进行二次燃烧；（3）进气空气中的氧含量对二次燃烧非常重要；（4）对于一定配方的含硼富燃推进剂，不同的空燃比，二次燃烧效率不同；（5）补燃室头部距离的增加能增强补燃室头部回流以及提高燃料在补燃室后段分布的均匀性；（6）在一定范围内，增加一次燃气喷嘴面积能提高冲压发动机燃料的燃烧效率；（7）进气道夹角对补燃室内燃料的燃烧影响复杂。

On the base of theorial study,ore experiment is made and feasible grind granularity and medicament system and the flow of Galenite flotation firstly is ascertained.

在优先选铅浮选过程中，经一次粗选，一次扫选，两次精选，所得到铅精矿中铅的品位达66.04%，铅的回收率为87.31%，银的回收率为70.40%，在浮选锌时，一次粗选，两次扫选，两次精选，所得锌精矿中锌的品位58.26%，锌的回收率为82.13%，银的回收率为19.36%，取得了银的总回收率达89.76%较先进的指标。最后，对浮选药剂与方铅矿、闪锌矿和银矿物的作用机理进行了深入探讨与分析，认为本实验中所使用的抑制剂和活化剂不会对银矿物的回收产生不利影响。

If we split up, I will be afraid to go out, Because no matter where, Have our memories, Everywhere I go I carry my乱逛of holding you, Looked at me with tears and I will be sad with you, Accompanied me crazy happy I accompany you, To say I am sorry I love you and you hesitate to half-day, Me into the future and your hard efforts to this end you Students will meet every time I think of the band you I am afraid to go to school afraid to go home two first-line of you, Almost all the money is spent on me for you, Because I have prepared a surprise for their happy and half-day to you, Even if there is a lot of baggage would not let you carry one, Crowded subway, holding my hand tightly for you, In the cold wind or rain, the rover will be waiting for me or you, Have taken the trouble to accompany me shopping for my clothes you choose to make any suggestions, Winter and summer vacations every year with me once you travel, Chaos because I play,乱吃things you get into the act, Every time I have been engaged in the collapse were still forgive me every time I come to see me inclusive of you.

如果我们分手了，我一定会害怕出门，因为无论到哪里，都有我们的回忆，背着我牵着我到处乱逛的你，看着我流泪会陪我一起伤心的你，陪着我发疯陪着我快乐的你，为了说一句我爱你而不好意思犹豫半天的你，把我纳入你的将来并为此拼命努力的你，每一次同学聚会都会想到把我带上的你，害怕我担心上学回家两点一线的你，几乎把所有的零花钱都花在我身上的你，因为给我准备了惊喜而自己开心半天的你，即使有一大堆行李也不肯让拎一件的你，拥挤的地铁里紧紧牵着我的手的你，在凛冽的寒风又或者飘泊的雨中还是会等我的你，陪我逛街不厌其烦地为我出主意选衣服的你，每年寒暑假陪我出去旅游一次的你，因为我乱玩，乱吃东西，胡作非为而大发雷霆的你，每一次都被我搞的崩溃却依旧每一次都原谅我包容我来找我的你。

The invention is characterized by the positive electrode material in which plural primary particles are flocculated and a secondary particle is formed, and the touch length of the primary particles is equivalent to 10 to 70% of the length of the whole periphery on the section of the touched primary particles.

该正极材料的特征在于：多个一次粒子凝聚而形成二次粒子，在该二次粒子的断面中，相对于上述一次粒子在上述断面中的全周的长度，上述一次粒子相互结合的长度为10-70％。

Again and again awakened from the dream, again and again in the dream of her by name, but I miss the mind in the wind around, add to the pain of my heart?

In that time, he was already very sick. But that was not the only time. In the past year, the condition of my dad wasn't stable. It happened few times that doctor told us to be ready with bad situation. Until now, I just unclearly remember, 2nd of March was the last day he got very sick and also that was the last time I saw him alive.

在那个时候，他已经病重了；但是他病重也不仅仅是那一次了，在过去的一年里，爸的病情并不稳定，多多少少也有出现过医生通知家人做好心里准备的情况，就现在才恍惚过来，2号那一次是他的最后一次病重，也是我最后一次看见活着的他。

My son 5 years old, when two-year-old on the occasional nosebleeds, small, 4-year-old when more than three months on the stream once every 10 days for half a year and a half months ago on the flow time, and also more than the original, to the hospital, said blood tests are normal, the point of medicine at the children do not love the beginning of .8 month almost 32 days on stream, but also very large, went to the hospital check, blood test or normal, open points syrup, and eat Chinese medicine granules, not a week, drug use is also a day on the 15 o'clock a sudden nose bleeding out, exhausted all the methods normally used only finally stopped, six o'clock in the morning and a stream, though not at night, and also have more than the original (the child was afraid I worry that the deal did not tell my own, I was based on the many large blood on the ground and pumping his college paper used judgments), or normal blood, the cream of the point that no matter, I was pleased, but the children come back again every day flow, and sometimes more than once or twice a day, which is a headache for two days and asked him if he do not understand how that specific pain law, is not the teacher the past two days that he said he did not love school is really a headache or a headache, I was to determine if a teacher said he does not love the child's school is a small trick.

5岁男宝宝经常流鼻血，最近两天又说头痛怎么办我的宝宝5岁了，两岁多的时候开始就偶尔流鼻血，量少，4岁多的时候开始三两个月就流一次，半年前开始隔十天半月就流一次，并且也比原来多，到医院验血说都正常，开点上的药水宝宝不爱点。8月分开始几乎三两天就流，还非常多，又去医院查，验血还是正常，开了点药水，和吃的中药颗粒，没到一周，还正用药，一天夜里3点就突然鼻子向外大量流血，用尽了平时用过的所有方法才好不容易止住了，早上六点又流了一次，虽没有夜里多，也是比原来都多(宝宝怕我着急，这次没告诉我自己处理的，我是根据地上的许多大血滴和他用过的纸抽团判断的)，血还是正常，开了点药膏，说没什么事，我挺高兴的，可是宝宝回来又是每天都流了，有时一天还不止一两次，这两天说是头痛，问他又说不明白具体怎么疼法，是不是老师这两天说他他不爱上课就说头痛还是真的头痛，我正在判断中，如果是老师说的他就不爱上课当然是宝宝的小把戏。
