POLO杯改制后的首站比赛8月在位于肇庆的广东国际赛车场展开，经过14圈的激烈较量，起点车队23号车手杜军及陈萧亮分获1.4T组和1.6L组第一回合决赛冠军。当日上午8点30分，POLO杯开始第一次自由练习，参赛车手十分珍惜时间均从一开始就驶上赛道，上午天气晴朗、赛道状况不错，车手们的练习成绩相对也比较出色；由于中午要进行排位赛，车手们在练习时不仅是熟悉赛道，更多的是提前模拟一下排位的情况。在中午进行了排位赛中，车手们上午练习调整的效果凸显；作为小钢炮级的1.4T组中，盛时贷RSR车队5号车手张嗛尚表现出色，在第二圈就以1分36秒565的成绩排在Q1的首位；北京锐思车队7号贺泽昱很快在第三圈做出1分36秒920的成绩位列第二，相对Q1，Q2比赛显得更为激烈，各车队参赛车手均卯足劲头，不断刷新最快单圈成绩；经过激烈竞争，最终ADK车队的27号车手戴灵昊夺得杆位，LINKY-racing车队的1号车手张亚琦位居第二，盛时贷RSR车队的5号车手张嗛尚列第三位；1.6L组方面，58号车手李麟、28号车手杨硕和33号车手张尧生分列前三位。下午由于一场暴雨来袭，正赛推迟至17点15分开始。狂风骤雨突袭后的赛道变得湿滑，对车手们形成不小的考验；赛会出示湿地牌，参赛车辆使用韩泰轮胎Z207雨胎，发车后1.4T组盛时贷RSR车队4号车手张嗛尚和LINKY-Racing车队4号车手邓保维率先取得先机，暂列第二、第三位；第十位发车的盛时贷RSR车队3号车手刘奕凭借实力一度追至第四位；很高兴遇见你车队25号车手李微、ADK车队8号车手陈义霖分列第五、第六位；此时的赛场仍飘着零星的雨点，赛道湿滑，事故频发，赛会出动了二次安全车；经过14圈的激烈拼争，最终起点车队23号车手杜军赢得1.4T组第一回合决赛的冠军，陈萧亮则成功摘取1.6L第一回合决赛桂冠。赛后，赛事组委会特邀中国汽车运动联合会的赛事总监张涛召开临时车手会，结合第一回合决赛中出现的事故，为车手们详细解读了比赛规则。赛车事故的出现就说明了车技和赛手的心理素质以及赛车的性能都属于事故原因之一。车技和赛车手们的心理素质只能靠他们自我提升和把控，而赛车的性能我们可以借助外部条件去完善。众多赛车故障中，普遍的故障都可以得到解决，需要说明的是发动机曲轴的故障还可以借助钨合金曲轴配重去改善；钨合金密度大可达18.6g/cm3，是锻钢曲轴和球铁曲轴密度的2倍多，则钨合金曲轴体积相对轻量化，从而节约成本；锻钢、球铁曲轴配重以及钨合金曲轴配重，钨合金曲轴配重的物理性能最好，其一在于钨合金材料的曲轴配重不与任何物体发生反应，从而抗腐蚀性更强延长了曲轴的使用寿命，其硬度和抗拉强度也较高，最重要的是钨合金材料的曲轴配重无毒无污染,再次满足了汽车曲轴配重材料的环保要求。钨合金曲轴配重优良的性能、低成本和工艺的日臻完善,已几乎完全取代了各种材料的曲轴配重。本站比赛是POLO杯改制后的首站比赛，从当日的赛况来看，参赛车队和车手对目前的比赛环境正在逐步适应中，相信赛手们用钨合金曲轴配重后赛车会更加猛力而迅速。

Precipitation method includes co-precipitation method and chemical precipitation method. Using precipitation method produce nano tungsten trioxide there will get a smaller powders particle diameter and more uniformity than using ammonium paratungstate producing tungsten trioxide powder. Prepared process as follows: First, mixing 1ml / L of Na2WO4 solution and Na2SnO4 solution then dropped this solution into boiling dilute H2SO4 with slowly, in this process should stirring constantly. Then aging, washing, filtering, drying and calcining to obtain SnO2-WO3 gas sensing powder materials. When doped 5% SnO2 additive can inhibit WO3 crystal grains to the growth and also can increase its gas sensing degree. Using chemical precipitation method to produce nano tungsten trioxide there is the process: Firstly, weighed 3.0g Na2WO3 and 0.005g one hundred and sixty thousand trimethyl ammonium bromides (CTAB) then make them dissolved in 10ml of distilled water. Then take 3ml solution dropwise adding to 5ml 3mol • HCL L-1with slowly. The solution was stirred for 1 to 2 hours after centrifugation the precipitate. With distilled water and acetone repeatedly washed it, and the resulting precipitate was placed in an oven at 80 ℃ dried to obtain precursor. Finally, the precursor was placed 300 ℃ muffle furnace, to obtain a nano tungsten trioxide.

有了密度大體積小、高硬度耐腐蝕的鎢合金漁墜子搭配其他釣具，接下來就是尋找好的黑魚釣點；釣黑魚雖不用打窩，但在遊釣過程中，也不可能滿溪潭釣，選擇易於黑魚藏身、尋食之處施釣能達到事半功倍的效果。以下幾點是釣黑魚的最佳釣點選擇：就能多獲魚。1.草邊明水處：有些黑魚藏在水草的邊緣，可在水草前方的明水處下鉤，輕點輕拖；如周圍有黑魚，點拖一二下就會咬鉤；同時釣者還要注意水草中的動靜，如有黑魚轉身，就要多點拖幾下，等待黑魚吞鉤。2.草洞口：有的溪潭草多且厚，就要找草洞口下鉤，草洞口氧氣足，也是黑魚捕食的好地方；如果發現洞口有黑魚開溜的情況，應迅速將鉤投入草洞中，上下拖拉抖動，開溜的黑魚離洞不遠，當它看到誘餌，會立刻殺個“回馬槍”。3.溪潭岸邊明水處：有的溪潭沿邊無草，有的只有稀疏的草，有的東一大塊草，西一大塊草，在岸邊有許多明水處，只要無人驚動，此處是常有黑魚設伏等食吃的；釣者可在近岸1米左右的水面點動拖拉，常會有黑魚咬鉤。4.浮萍下麵好釣魚：有的溪潭水面被浮萍覆蓋，而黑魚就藏在浮萍下麵，釣者可在浮萍下拖釣，往往可釣獲可觀的黑魚。5.時到中秋，有菱角的溪潭，大面積菱秧敗落，只留下東幾棵，西幾棵，有的遠離岸邊，釣者可用長竿長線輕拋鉤至菱盤邊拖釣。總之，以上兩種釣點的選擇還必須根據水情、魚情等情況，隨機應變，靈活操作。

Non-sag tungsten wire diameter incandescent bulb poor consistency is an important reason to make the optical parameters of the ultra-poor, and some will affect the life of the lamp. Apply a small amount of tungsten in addition to high-temperature furnace used for heating materials, tubes of the heater and the composite stiffener endures, most of them for the production of incandescent lamps and tungsten halogen lamps and gas discharge lamp filament electrodes. For use as a gas discharge lamp cathode tungsten or tungsten rods, in order to reduce the electron work function, should be 0.5 to 3% of thorium, called thorium tungsten filament. Because Thorium is a radioactive element, pollute the environment, instead of useful cerium thorium wire made of tungsten or tungsten cerium rod. But the evaporation rate of cerium, the gas tungsten or tungsten filament cerium rod can be used for small-power discharge lamp. Once tungsten by high temperature recrystallization becomes very brittle, in case of a shock or vibration can easily break. In some of the requirements of high reliability electric light source products in order to prevent filament breakage, often joined in the anti-sag tungsten wire 3 to 5% of rhenium, called tungsten-rhenium wire, which can make the extension of tungsten brittle transition temperature drops to room temperature or below. This is a very strange effect of rhenium, has not yet been able to find a substitute element rhenium, tungsten produce the same effect. Tungsten at room temperature have good acid and alkali capacity, but in the humid air easily oxidized, so fine tungsten wire can not be stored for too long in a humid environment. Also tungsten at 1200 ℃ and down to begin with the carbon from the reaction of tungsten carbide, so the filament to burn hydrogen treatment should pay attention to this issue, tungsten or graphite lubricant react with the surface, the filament would become brittle fracture.
