Spline shaft gear is our life and production, one of the more common shaft, which is composed of three parts by the spline, flat shaft, gears, connected by means of spline points: inside and outside Spline Spline, by type, : rectangle spline and Involute Spline, Spline Shaft power transmission shaft than the other products, because the hole axis with the hub directly and evenly produced more tooth and slot, the joint acceptance more uniform; by shallow groove, the tooth root stress concentration of the small shaft and hub to weaken the strength of less; more teeth, the larger the total contact area, which can withstand greater loads; axis parts with the axis of neutral, and this high-speed and precision machinery is very important; -oriented, and this dynamic linking is very important, also has good gear transmission, the number of teeth because it more closely meshing gears meshing with the gear gap between the small role: The main control of the speed of mechanical operation, as well as mutual energy transfer, the use of the gearbox.
花键齿轮轴是我们生产生活中比较常见轴类之一，它由三部分组成花键、平轴、齿轮，按花键的联接方式分：内花键和外花键，按种类分：矩形花键和渐开线花键，花键轴力的传递性要强于其他轴类产品，因为在轴上与毂孔上直接而均匀地制出较多的齿与槽，故联接受力较为均匀；因槽较浅，齿根处应力集中较小，轴与毂的强度削弱较少；齿数较多，总接触面积较大，因而可承受较大的载荷；轴上零件与轴的对中性好，这对高速及精密机器很重要；导向性好，这对动联接很重要，齿轮也具有良好的传递性，因为它的齿数较多，啮合紧密，齿轮与齿轮之间啮合间隙小，作用：主要控制机械运作的速度以及能量相互的传递，使用于变速箱中。
In comparison with bugle shaped nozzle, bifurcated nozzle downward jet angle 45°, cow-nose nozzle and three-hole nozzle, in all, the last two are better than the former and bifurcated nozzle downward jet angle 45 is better than bugle shaped nozzle; Cow-nose nozzle is helpful for guaranteeing the product's quality, in order to protect jet flow from eroding the strand at narrow face, gain uniform temperature distribution at cross section and decrease heat flux, adding the block's width to 100 mm. Three-hole nozzle is advantageous to increase flux and casting speed, but should avoid weak shell thickness in the center broad. In the real production, setting the SEN's immersed depth or plugging the hole at the bottom can adjust the flow and temperature distribution in the mold.
对比喇叭形水口，双侧孔水口(45°)，牛鼻子水口和三孔水口，总的说来后两者优于前两者；而双侧孔水口(45°)又优于喇叭形水口；牛鼻子水口和三孔水口比较各有特点，前者对保证铸坯质量有利，为防止流股对窄面的冲击，增加挡块宽度到100 mm，可使结晶器横截面上温度分布更加均匀，降低窄面热负荷；后者对增加流量，提高拉速非常有利，但要防止中孔射流过强导致铸坯中心坯壳变薄，在实际生产中可通过控制水口浸入深度或塞住浸入式水口的底孔来调节结晶器中的流动与温度分布状态。

The results show that 610 ℃ is the key point of the temperature—viscosity relationship of aluminum foam. While the melt temperature is below 610 ℃, the viscosity elevates greatly with decreasing temperature. While melt temperature is above 610 ℃, the viscosity elevates slowly with decreasing temperature. The uniform of foaming agent is improved with increase of melt temperature, stirring speed and dispersing time. However, the aggregation of TiH2 still exists stirred at rotation speed 3000 r/min for 30 s. Three approaches are found to be effective to improve the uniform of TiH2 in the melt route precursor: disperse TiH2 in the viscosity-temperature non-sensitive area of aluminum alloy, density the cast precursor by pressing, and use a rotation speed higher than 3000 r/min.

The company had stabilized the Web system that ran 1 year to appear recently performance issue, answer speed very slow, the system registers new module ceaselessly, increase new module to be able to bring certain load every time, because the configuration file to load of a large number of module and itself of initiative data cache took up, be a large number of content, bring about leave an user the operation memory space is little cause, best method uninstalls no use namely module and clear cache data, but leader or the small effect code that insist to ask to check code and eliminate wasteful memory, the system is older, this thing is done can not allow easy, breathe out ah... when be being checked, the type assembles to having data in discovering a method return have 2 kinds of kind, null and New List, the system is developed by a lot of people, according to looking to was opposite apparently on code these detail form uniform standard, also can understand nevertheless... look for a person to ask casually, after telling them next, normative respect is united as far as possible, return Null as to the problem above or found array of an empty content, because the system is strong occurrence memory problem, united an opinion almost, with Null... really such?
最近公司一个已经稳定运行了1年的web系统出现了性能问题，响应速度非常慢，系统是不断注册新的模块的，每次增加新模块都会带来一定负载，虽然很快就断定是由于大量模块的配置文件加载与初始数据缓存本身占用了大量内容，导致留给用户操作内存空间小造成，最好的办法就是卸载无用模块和清理缓存数据，但领导还是坚持要求检查代码并消除浪费内存的低效代码，系统比较大，这件事做起来可不容易，呵呵…在检查的时候，发现方法中对无数据集合类型的返回有2种方式，Null和new List，系统是由很多人开发的，根据代码上看很明显没有对这些细节形成统一的规范，不过也能理解…随便找人问了问，然后告诉他们以后规范方面尽量统一，至于上面的问题返回null还是创建一个空内容数组，由于系统刚出现内存问题，几乎统一了意见，用null吧…真是这样吗？
