均衡的作用是“削峰添谷”,就是说使用均衡有三种思路,1:使用均衡来平衡声场的缺陷,可以用音频信号发生器来测试,方法是将信号发生器发出的对应均衡器的各频率音频信号接入系统中,在声场中放一电容话筒来接收,通过均衡器各频率的推子来平衡各个频率。或者放一比较熟悉的音乐,以对音乐的了解来调试均衡的各个音域2:用均衡器来调节特殊的声场效果,比如DJ和大型演唱会的调整就是不一样的,均衡也可以用来调整乐器的音色,多听,慢动手,慢慢就会调的,当然,事先得记住各个音源的共振峰。3:用来抑止反馈,这个比较简单,有的均衡自带反馈侦测,哪个频率发生回受,哪个频率点上的指示灯就会点亮,如果没有这个功能,就只能看经验和耳朵了。

一道不等式证明题(用柯西不等式证的)的一些疑问

你的答案显然是不对的逻辑上有错误就举个最简单的例子吧B+1>=B,B<=1难道B+1就恒大于1吗,显然不一定啊你的那个题目:分析:既然你已经用柯西,一步反向,这样的话我们第一步不能用柯西不等式了我是这么做得:第一步因为yz<=(y^2+z^2)/2,zx<=(x^2+z^2)/2;xy<=(x^2+y^2)/2这样的话左边就>=2/3(sigmax^2/(y^2+z^2))根据齐次性,不凡令x^2+y^2+z^2=1,x^2=m,y^2=n,z^2=r那么sigmax^2/(y^2+z^2)=sigma(m/(1-m)根据f(x)=x/(1-x)的下凸性质得到sigma(m/(1-m)的最小值就出来了。

赤藓糖醇可以长期吃吗 赤藓糖醇能长期吃吗

1、赤藓糖醇可以长期吃的。赤藓糖醇是新一代健康糖醇,能量值为0,人体摄入不增加脂肪。赤藓糖醇是小分子的甜味剂,它不被机体内酶系统所代谢,不会影响正常的糖代谢,所以可以吃。 2、而且食用后血糖水平和血液胰岛素水平不会发生明显变化,肥胖人群和糖尿患者可以放心食用。 3、有些爱吃甜食有怕胖的人群选择0度活性糖最为餐桌甜味调味料,替代蔗糖制作低热量的甜食,这种0度活性糖其主要配料也是赤藓糖醇。

做MTT时,96孔培养板细胞浓度该是多少?

博凌科为解答:我觉得细胞的浓度并不需要那么精确,关键是接种于每孔的细胞数就大致处于同一水平。比如我做MTT,起初用的细胞浓度为5000/ml,每孔100ul,培养3天观察,发现细胞数太少,各孔OD值反面难于比较。后来我换用 10000/ml,结果就很好。当然细胞数也不能太多,这其实取决于你细胞的生长速度,生长快的细胞,可接种浓度低点。这主要是使细胞增殖率不致受处理因素之外的其他因素影响,比 如接触抑制,营养竞争。总之,做MTT时细胞数应较低,目的就是为了排除其他因素的影响,以使每孔细胞生长情况尽可能地反映出处理因素的影响。细胞接种的浓度和你的实验目的、要求、细胞种类、处理因素的特殊要求都有关系。没有简单的,每孔接种多少的一个标准。当然,可以用楼上建议的浓度开 始摸索。同时,注意肿瘤细胞核正常细胞的生长数度也不一样,前者生长快,后者慢,细胞数的量也有讲究。到底多少合适,得根据你的实验具体要求来摸索。我做 b16转染时,因为脂质体要求细胞融合度为30%-50%,曾经没孔接种过300-500个细胞,效果非常好,
