TV set in every home has not been merely among imaginary depiction in fantasy fiction, coming true nowadays as it has become even a thing that can be thrown away without pity. Therefore, number as the basic privilege, most entertainment corporations utilize it as the access to profits by broadcasting ads, movies or other programmes. As the proportion of atmitting and using people against the none-users is high, in most country, the TV can be grouped into one of the main medium concomitant with the peak of radio.
Main medium as we group it, it contains main infro. . The ken broaden by TV is undeniable. Without trudging in the igneous desert we "wow" the pyramid at home, no danger from sharks we visit coral reef with our mouth in shape of O and wearing pants and T-shirts, we have a glance of the Arctic, holding a cup of ice-cream. Broden easily, broaden fast, that's what TV bring to us.
Inferior things, however, are brought by TV as well. Left the violence on TV, which should be concerned by the government, unsaid but the health concerned by the every of us is undermined by long term watching TV. Albeit it is so, this is never to say that we should banish TV, as the advantages overweigh the counterpart.

The role of transistor Transistor, is one of the most common basic components, the role of main transistor current amplification, he is the heart of electronic circuit components, are essential components of large scale integrated circuit is transistor. Transistors are the basic institutions of a semiconductor substrate in the production of the two in close proximity of the PN junction, the two blocks of semiconductor PN junction is divided into three parts, the middle part of the base area, on both sides of part of the emitter and collector areas, arrangement of There are two PNP and NPN, from the corresponding electrode leads the three areas, namely e base emitter and collector b c. Between the emitter and the base region of the PN junction is called the emitter, collector and base region of the PN junction between the collector called. Very thin base region, while the emitter thick, impurity concentration of large, PNP-type transistor emitter "launch" the hole, its moving direction and current direction, and therefore the arrow to where the emitter; NPN-type transistor emitter "launch "is the free electron, its moving direction and current in the opposite direction, so the emitter arrow out. Emitter arrow out. Arrow points to the emitter PN junction in forward voltage is under the direction of conduction. Silicon germanium transistor and PNP transistor has two types of type and NPN type. Transistor is a control element, the role of very large transistors, can be said that without the invention of the transistor is not the modern information society so diverse, tubes, his predecessor, but the size of a large tube enormous power, has now been eliminated. Transistor size is mainly used to control current to total emitter Connection Example (signal from the base input, the output from the collector, emitter grounded), when the base voltage UB has a small change, base current IB will follow a small change, subject to the control of base current IB, the collector current IC will be a great change, the greater the base current IB, the greater the collector current IC, whereas the more base current small, the collector current is also smaller, which control the base current the collector current changes. However, changes in the collector current changes than the base current is much greater, and this is the current amplification transistor. Just said is the transistor current amplification effect, and its essence is the transistor base current can change slightly to control the volume of the larger collector current variation. This is the most basic and most important transistor characteristics. We will ΔIc / ΔIb as the ratio of current amplification transistor, with symbol "β" said. Current amplification factor for a transistor is only a fixed value, but with the transistor's base current when the work of change there will be some modifications. According to our analysis of the role of transistors it can become weak signal strength of the signal must, of course, continue to follow the conversion of energy conservation, it is only the power of the signal energy into the energy Bale. An important parameter is the transistor current amplification factor β. When the transistor's base, adding a small current, the collector can get a current is injected into the current β-fold, that the collector current. Collector current with base current of change, and small changes in base current can cause large changes in collector current, which is the transistor's amplification. The role of transistor switches are electronic, with the other components also constitute the oscillator, in addition to the role of regulator transistor there. 【譯文】 晶體三極管的作用 晶體三極管，是最常用的基本元器件之一，晶體三極管的作用主要是電流放大，他是電子電路的核心元件，現在的大規模集成電路的基本組成部分也就是晶體三極管。
三極管基本機構是在一塊半導體基片上制作兩個相距很近的PN結，兩個PN結把正塊半導體分成三部分，中間部分是基區，兩側部分是發射區和集電區，排列方式有PNP和NPN兩種， 從三個區引出相應的電極，分別為基極b發射極e和集電極c。發射區和基區之間的PN結叫發射結，集電區和基區之間的PN結叫集電極。
基區很薄，而發射區較厚，雜質濃度大，PNP型三極管發射區"發射"的是空穴，其移動方向與電流方向一致，故發射極箭頭向里；NPN型三極管發射區"發射"的是自由電子，其移動方向與電流方向相反，故發射極箭頭向外。發射極箭頭向外。
發射極箭頭指向也是PN結在正向電壓下的導通方向。硅晶體三極管和鍺晶體三極管都有PNP型和NPN型兩種類型。
三極管是一種控制元件，三極管的作用非常的大，可以說沒有三極管的發明就沒有現代信息社會的如此多樣化，電子管是他的前身，但是電子管體積大耗電量巨大。

歷史老照片不能說的秘密慈禧軍閥明末清初**晚清knowledge base in this paper is partially based on these data. On the hand, Dornerburg developed a method to judge different faults by rating pairs of concentrations of gases, e.g., CH/H, GH/C3H4, with approximately equal solubility and fusion coefficients. Rogers established mare comprehensive ratio codes to interpret the thermal fault types with theoretical thermodynamic assessments. This gas ratio method was promising because it eliminated the effect of oil volume and simplified the choice of units. Moreover, it systematically classified the diagnosis expertise in a table form. Table 1 displays the ratio method as proposed by Rogers. The dissolved gas may vary with the nature and severity of different faults. By analyzing the energy density of faults, it's possible to distinguish three basic fault processes:overheating(pyrolysis), corona(partial dischatge) and arcing discharge. Corona and arcing arise from electrical faults, while overheating is a thermal fault. Both types of faults my lead to deterioration, while damage from overheating is typically less than that from electrical stress. Infect, different gas trends lead to different faulty types, the key gas method is identified. For example, large amounts of CH and H are produced with minor arcing fault 4 quantities of CH 2aid C2H2 may be a symptom of an arcing fault. 3. THE PROPOSED DIAGNOSTIC EXPERT SYSTEM This study is aimed at developing a rule-based expert system to perform transformer diagnosis similar to a human expert. The details of system processing are described below. 3.1 The Proposed Diagnostic Method Diagnosis is a task that requires experience. It is unwise to determine an approach from only a few investigations. Therefore, this study uses the synthetic expertise method with the experienced procedure to assist the popular gas ratio method and complete practical performance. 3.1.1 Experienced Diagnostic Procedure The overall procedure of routine maintenance for transformers is listed. The core of this procedure is based on the implementation of the DGA technique. The gas ratio method is the significant knowledge source. Some operational limitations of the gas ratio method exist. The ratio table is unable to cover all possible cases. Minimum levels of gases must be present. The solid insulation involving CO and CO are handled separately and the gas ratio codes have been developed mainly from a free-breathing transformer. Other diagnostic expertise should be used to assist this method. Norms, synthetic expertise method and data base records have been incorporated to complete these limitations. The first step of this diagnostic procedure begins by asking DGA for an oil sample to be tested. More important relevant information about the transformer's condition, such as the voltage level, the preservative type, the on-line-tap-changer(OLTC) state, the operating period and degassed time must be known for further inference. Norms(criteria) Set up by TPC power transformers' gas characteristic data are then used to judge the transformers' condition. For the abnormal cases, the gas ratio method is used to diagnose transformer fault type. If different or unknown diagnosis results are found from these ratio methods, a further synthetic expertise method is adopted. After these procedures, different severity degrees are assigned to allow appropriate corresponding maintenance suggestions. 3.1.2 Synthetic Expertise Method The ratio trend, norms threshold, key gas analysis and some expertise are considered as different evidences to confirm some special fault types. In other words, more significant evidences have been collected for some special fault type, better assessment of the transformer status is obtained. The ratio trend can be seen as a modification of the conventional gas ratio and key gas method. Obviously, the above gas trends should be incorporated with other evidences under the experienced procedure for practical use. Norms threshold, the gassing rate, the quantity of total combustible gas(TCG), the TPC maintenance expertise and the fuzzy set assignment are all important evidences considered in the synthetic diagnosis. Other expertise based on a transformer historical data base is also used to analyse the characteristics of a case transformer. Section 3.4 gives some details of these rules. 3.2 Expert System Structure The proposed diagnostic expert system is composed of components, working memory, a knowledge base, an inference engine and a man-machine interface. Working memory (global data base) contains the 。
