Care Internet only Guest of a rich ---------------------------------------------------------------------------- It is Laozhou below the comment to this article and oneself view 1, the ignorance to adversary, this has been mentioned above big head, look down on adversary, the product that perhaps does not understand adversary, dynamic; The idea with a lot of new as a result flatter oneself, actually others had been done early 2, the ignorance to the industry, this also is above had mentioned; Nevertheless besides newest trends, academic, product, a lot of people lack his analysis and judgement to the industry of the place, the result can resemble myna be being become euqally only a microphone, meet only in products plan respect blindly imitate 3, the ignorance to oneself, in the specific details that the person often is immersed in him place easily to do, see very local thing only, edit to wait not to understand to technology, design normally for example, and the thing that the technology puts the view in program, code only; And if do not know structure of catenary of oneself product characteristic, target, job,wait more the thing of global sex, the problem is done not have in traditional automation line job, greater value cannot be produced in the job that gives priority to with mental work in Internet, cannot obtain progress 4, the spokesman that likes to do people, no less than is big say, the individual the habit serves as the habit of broad user, arrive deep really rarely however in the user, listen the think of a way of themselves, like to use affirmation very much, of course, certain, natural such positive statement, support without real data at all however 5, nearsightedness, impatient.

只关心互联网梁铁欣的一篇博客----------------------------------------------------------------------------以下是老周对此篇文章的评论和自己的看法 1、对对手的无知，这是大头上面提到过的，看不起对手，或者不了解对手的产品、动态；结果很多自以为新奇的点子，其实别人早就做过了 2、对行业的无知，这也是上面提到过的；不过除了最新动态、理论、产品外，很多人对所在的行业缺乏自己的分析和判定，结果就只会像八哥一样当个传声筒，在产品设计方面则只会一味的模拟 3、对自己的无知，人往往轻易陷入自己所做的具体细节里，只看到非常局部的东西，例如编辑通常对技术、设计等不了解，而技术则只把目光放在程序、代码的东西；而假如不了解自己的产品特色、目标、工作链结构等更全局性的东西，在传统的流水线工作中没有问题，在互联网以脑力劳动为主的工作中则无法发挥出更大的价值，无法取得进步 4、喜欢做人民的代言人，正如大头说的，将个人习惯作为广大用户的习惯，却很少真的深入到用户中去，倾听他们自己的想法，很喜欢用肯定、当然、一定、自然这样的肯定词，却根本没有实际的数据支持 5、短视，急躁。

In this article two functional modes of the Fly-back Converter (Continuous Conduct Mode and Discontinuous Conduct Mode) are particularly analyzed, which include their characteristics, applications, the critical pattern of two functional modes is argued, both the exact boundary from the angle of circuit parameters is crystallized, at the same time, basic principle of PFC under the DCM mode is introduced, which settle theoretical basis for the subsequent design; by establishing the mathematic model of the converter, a further investigation of the configuration is made, qualitatively and quantitatively, analyzed to settle exactly theoretical basis for the subsequent emulation and the experimental parameter; from the angle of steady-state analysis, the transfer function of the system is deduced to establish dynamic small-signal state equation, emulating the system with the help of matlab, then according to the simulation result and the theory of PFC revise the system, lastly, we adopt the project which add a zero-pole compensator to the voltage loop, by this way, a satisfied system performance is gained and the PFC scheme is ensured successfully; finally, based on the previously-done work, we combining with the situation of specific design requirement, acquired the numerical value of each unit devices in this converter

From the special viewpoint of information and belief, our analysis finds that through refusing free information the current self can restrain future selves' ill tendency when the external information are static stock. This conclusion can be supported by finite or infinite horizon model as well. When external information are dynamic flow, current self's controlling instrument is forestallment, sometimes he would invest even under negative net present value. Selective memory can also serve as a controlling instrument, current self selectively convey information to future selves.

本文选取了信息与信念这一独特视角，深入探讨现期自我的控制手段，研究发现：当信息为静态的存量时，现期自我可通过拒绝外生信息克制远期自我的不良倾向，该结论在有限期或无限期模型中均成立；当信息为动态流量时，时间不一致矛盾将侵蚀等待的期权价值，现期自我会以抢先行动的方式拒绝进一步信息，甚至采取NPV为负的行动；现期自我也可通过选择性记忆向远期自我传递信息，这就是信息传递阶段的控制手段。
