内容:基于物理和化学过程,因此表达受内外环境调节,不
稳定。
,拥有人工智能的独立的人才是最可怕的,因为人具有本能,而这个本能的表达在个体上具有不稳定性,会受到情绪的强烈影响。,幸运的是,虽然本能在个体上表达不稳定,但是在群体上基本是稳定的:正是因为SpaceX的每一个员工都有相似的本能,因此其中一两个精神失常的人(比如Musk)轰炸五角大楼的决定会被其他人阻止。,因此,要维护社会的和谐稳定,我们就需要禁止每一个个体拥有过多的能力,比如我们禁止很多国家拥有核武器、大规模杀伤性武器,比如我们禁止个人拥有枪支弹药,实际上都是为了把这些能力集中在集体手中,以避免个体本能表达的不稳定造成的危害

内容:10.25J,平均加速度23688.31第四级平均离开速度:76.42m/s,40.29J,ΔE=10.87J,平均加速度24332.90根据以上数据可以发现,能量一直是在平稳的增加中,加速度变化也非常稳定,没有用的原因主要是基于以下考虑:首先这是用于积累实验数据的测试机,薄膜电容最接近理想电容,在系统调试时可以较少考虑电容的影响;其次是即使在军事等实用中,体积并不是一个大的问题,性能稳定是最重要的。

生物学
内容:与事实作比较:稳定性的程度;突变的不连续性 最后,让我们用生物学的事实同理论的描述作比较。,物种将会抛弃这些个体,并将通过自然选择把稳定的基因集中起来。 ,突变体的稳定性有时是较低的 至于在我们的繁育试验中出现的、被我们选来作为突变体以研究其后代的那些突变体,当然不能指望它们都表现出很高的稳定性。,温度对不稳定基因的影响小于对稳定基因的影响 这一点使我们能够检验我们的突变可能性的公式:t=cEXP(W/kT)(我们还记得,t是对于具有阈能W的突变的期待时间。),例如,一个不稳定的突变体的X射线突变率,平均起来并不高于稳定的突变体。

内容:很多同学忽略了(看一下反激开关电源原理就懂得了)4.电弧形状很重要:金黄的电弧音质反而没有紫色的电弧音质好 我想可能是等离子体冷却需要时间吧 电弧不要追求长,虽然电弧长度和音量正相关,把电弧长度拉到能自主击穿且稳定即可,以空载时候没有较大的咝咝声为准5.电极很重要:尤其是阴极 实验的时候阴极发热很大,连铁钉长时间都可以烧红 但是我发现烧红的阴极音质反而更好了 电弧更稳定了 另外球星的阴极比尖的阴极要好6.周围环境也很重要

内容:调整失调电压的源极电阻RS中采用了可调电阻,但电阻每次调整后都需要1min以上的稳定时间,在此期间失调电压会持续变化,导致调压不准确。,这次改用开关电阻阵列+可调电阻的方案来处理电压失调,几乎消除了可调电阻稳定过程对测量的影响。,然而,如果继续使用可调电阻,则输出电压是不可能稳定下来的。
