The study probe into at when extreme rainfall happenning incident research purpose department on city, estimate its flow of flood crest to defend and provide disaster relief the reference carried on the exercise of in follow-up ; While estimating the the depth of extreme rainfall , use separately: World Meteological Organization statistic method, storm transposition and dew point adjustment method and average recurrence interval rainfall depth factor method, inquire into and act as river valley wutu the upper reaches of Keelung and collect in the water area separately, wutu station with flood-diversion stands in the Huo-Shao-Liao station before Yuan-Shan-Tzu flood-diversion, the depth when the extreme rainfall happens separately, step forward and mix the set of design hyetograph by extreme rainfall ,finally,mix geomorphologic instantaneous unit hydrograph afterwards, in order to estimate the flow of flood crest produced cause by extreme rainfall incident .

本文之研究目的系探讨当极端暴雨事件发生於都会区时，推估其洪峰流量以作为后续防救灾演练之参考。在推估极端暴雨之降雨深度时，分别采用：世界气象组织统计法、暴雨移置与露点调整法及平均重现期距雨量因子法，分别推求当基隆河流域五堵上游集水区，员山子分洪前之火烧寮站与分洪后之五堵站，分别发生极端暴雨时之雨量，进一步将极端暴雨量套配设计雨型，最后再搭配地貌型瞬时单位历线模式，以推估因发生极端暴雨事件而产生之洪峰流量。

S1 is then changed to position 1. The voltage stored on C1 is inserted between the output and inverting input of the amplifier and the output of the amplifier changes by VIN to maintain the amplifier input at the input offset voltage. The output then changes from (VOS + IbiasR2) to (VIN + IbiasR2) as S1 is changed from position 2 to position 1. Amplifier bias current is supplied through R2 from the output of the amplifier or from C2 when S1 is in position 2 and position 1 respectively. R3 serves to reduce the offset at the amplifier output if the amplifier must have maximum linear range or if it is desired to DC couple the amplifier.

接着 S1 拨到位置 1，使 C1 的电压加在放大器的输出端和反相输入端之间，(由于电容端电压不能突变，所以)输出端的电压将产生大小等于 VIN 的变化，使放大器输入端维持输入失调电压，即当开关 S1 从位置 2 拨到位置 1 时，输出端电压将从(VOS + IbiasR2)变为(VIN + IbiasR2)。S1 处于位置 2 时，放大器的偏置电流是由输出端经电阻 R2 提供的，当 S1 转向位置 1 时则由 C2 提供。R3 的作用是降低输出失调电压，如果要求放大器具有最大的线性范围，或者采用直流耦合，就应该使用该电容。

If a phototypesetter is an intermittence type, the memory of controller is used only to buffer a section and the buffer of whole page lattice is unnecessary. If a phototypesetter is an uninterruption type, a section of lattice is only generated and buffered for every time and then be converted into black-white sectional information, whose information quantity is much less, by microprogram for buffering whole printed sheet. On scanning, the black-white sectional information is real-restored into lattice to output.

当照排机是"走走停停"类时，控制器的存储器只需缓冲一段，而不必缓冲整版点阵；当照排机是"不许停顿"类时，则用分段方法每次只生成一段点阵并缓冲，然后用微程序把这一段点阵转换成信息量少得多的黑白段信息作整版缓冲，扫描时在实时下把黑白段信息复原成点阵输出。

Interestingly, corporate managers have no trouble understanding that point when they are focusing on a business they operate: A parent company that owns a subsidiary with superb long-term economics is not likely to sell that entity regardless of price."Why," the CEO would ask,"should I part with my crown jewel?" Yet that same CEO, when it comes to running his personal investment portfolio, will offhandedly - and even impetuously - move from business to business when presented with no more than superficial arguments by his broker for doing so. The worst of these is perhaps,"You can't go broke taking a profit." Can you imagine a CEO using this line to urge his board to sell a star subsidiary? In our view, what makes sense in business also makes sense in stocks: An investor should ordinarily hold a small piece of an outstanding business with the same tenacity that an owner would exhibit if he owned all of that business.

有趣的是企业经理人在认定何者才是自己本业时，从来就不会搞不清楚情况，母公司是不会单纯因为价格因素就将自己旗下最优秀的子公司给卖掉，公司总裁一定会问，为什么要把我皇冠上的珠宝给变卖掉，不过当场景转换到其个人的投资组合时，他却又会毫不犹豫地，甚至是情急地从这家公司换到另一家公司，靠的不过是股票经纪人肤浅的几句话语，其中最烂的一句当属，你不会因为获利而破产，你能想象要是一家公司的总裁用类似的方式建议董事会将最有潜力的子公司给卖掉时，就我个人的观点，适用于企业经营的原则也同样适用于股票投资，投资人在持有一家公司的股票所展现的韧性应当与一家公司的老板持有公司全部的股权一样。

Nor was the party over in 1938 for an investor： Though the $40 invested in 1919 in one share had turned into $3，277 by the end of 1938， a fresh $40 then invested in Coca-Cola 16 有趣的是企业经理人在认定何者才是自己本业时，从来就不会搞不清楚情况，母公司是不会单纯因为价格因素就将自己旗下最优秀的子公司给卖掉，公司总裁一定会问，为什么要把我皇冠上的珠宝给变卖掉，不过当场景转换到其个人的投资组合时，他却又会毫不犹豫地，甚至是情急地从这家公司换到另一家公司，靠的不过是股票经纪人肤浅的几句话语，其中最烂的一句当属，你不会因为获利而破产，你能想象要是一家公司的总裁用类似的方式建议董事会将最有潜力的子公司给卖掉时，就我个人的观点，适用于企业经营的原则也同样适用于股票投资，投资人在持有一家公司的股票所展现的韧性应当与一家公司的老板持有公司全部的股权一样。

First, when there is no-risky security but no consideration on transaction costs, based on the concept of asymptotic returns rate, we present the concept of asymptotic efficient frontier of portfolio and its determining method.

当有交易成本存在时，我们说明：若标的股票的投资比例在非交易区域时，投资者不需要进行交易；而当股票投资比例超出非交易区域时，投资者需要进行交易使标的股票的投资比例回到非交易区域内。

Crysalline shape and behavior were investigated by polarizing microscope and wide angle X-ray diffraction spectrum.The results show that the value of impact strength is maximum while tensile strength,flexural strength,modulus and vicat softening temperature are least when the content of β form nucleator is 0.05 phr.

结果表明，当β成核剂的含量在0.05份时，冲击强度达到最大值，而拉伸强度、弯曲强度、模量、维卡软化温度等达到最小值；当β成核剂含量为0.05份以下时，随着β成核剂含量增加，PP中β晶结晶度大幅度上升，同时α晶结晶度大幅度下降；增加β成核剂用量至大于0.10份时，β晶结晶度略为下降，而α晶结晶度上升，但总结晶度随着β成核剂含量增加呈现上升趋势。

Few grown-ups come out well in this story. Hungarian officials were callous and uncomprehending. Friends proved unreliable. Mr Marton's American employers dithered, while American diplomats doubted the Martons' reliability. Mr Marton's bravado remains incomprehensible, even to his adoring daughter 50 years later. In the midst of it all are two little girls, precociously aware of the dramas swirling around them, left crying on the pavement when their mother is snatched from their home to join their father in jail. A Utah couple, reading that the girls were being brought up by strangers, offered, in vain, to adopt them.

在这个故事里很少有成年人可以被释放，匈牙利政府是无情的、毫不谅解的，朋友被证明是靠不住的，当美国外交官们怀疑Marton夫妇的可靠时，Marton先生的雇主也动摇了，Marton先生的逞能是难以理解的，即使50年后对他的令人尊敬的女儿也是如此，在这其中，戏剧性的场景围绕着他们，当这两个小女孩的买卖被逐出同它们的父亲到监狱会和时，她们被哭泣着遗弃在街头，一对犹他州的夫妇读到这对女孩被陌生人带大时，他们主动提出无偿收养她们。

So I might be of the brake when I come over the ledge and on the brake on this rock when I get some good traction and then and then off when the traction is a kind of loose, and definitely off the brake when I come down at this corner and I going to make a direction change, so my front wheel can roll fluently with traction.

这里有土会让煞前煞时打滑不过这个石头可提供煞车抓力，所以当我过岩石时我会放掉煞车，然后上这个石头有比较好的抓地力后再刹车，然后当抓地力减弱时再放掉煞车，我下这个转角一定放掉煞车而且我要转弯，所以我前轮可以流畅的滚过且能抓地。

Here is some dirt that is pretty slippery to get on the front brake hard in these places but for instance here is a rock that is going to provide good traction. So I might be of the brake when I come over the ledge and on the brake on this rock when I get some good traction and then and then off when the traction is a kind of loose, and definitely off the brake when I come down at this corner and I going to make a direction change, so my front wheel can roll fluently with traction.

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
