电路 2 电路或电网络由以某种方式连接的电阻器，电感器和电容器等元件组成。如果网络不包含能源，如电池或发电机，那么就被称作无源网络。换句话说，如果存在一个或多个能源，那么组合的结果为有源网络。在研究电网络的特性时，我们感兴趣的是确定电路中的电压和电流。因为网络由无源电路元件组成，所以必须首先定义这些元件的电特性。就电阻来说，电压-电流的关系由欧姆定律给出，欧姆定律指出：电阻两端的电压等于电阻上流过的电流乘以电阻值。在数学上表达为： u=iR (1-1A-1)式中 u=电压，伏特；i =电流，安培；R =电阻，欧姆。纯电感电压由法拉第定律定义，法拉第定律指出：电感两端的电压正比于流过电感的电流随时间的变化率。因此可得到：U=Ldi/dt 式中 di/dt =电流变化率，安培/秒； L =感应系数，享利。电容两端建立的电压正比于电容两极板上积累的电荷 q 。因为电荷的积累可表示为电荷增量 dq 的和或积分，因此得到的等式为 u=，式中电容量 C 是与电压和电荷相关的比例常数。由定义可知，电流等于电荷随时间的变化率，可表示为 i = dq/dt。因此电荷增量 dq 等于电流乘以相应的时间增量，或 dq = i dt，那么等式(1-1A-3)可写为式中 C =电容量，法拉。

But after all this is the biggest mark that beauty left, people can not at all think over this is actual beauty or not, or just the unction that beauty left incidentally. Before knowing beauty, people have to accept beauty passively, only by now this material beauty is true and reliable, only it still maintain a hope of exploring the knowability of beauty, which means the research on it can have a specific result.

但这毕竟是美留下的最大痕迹了，人们根本无法考虑这是不是真实的美，以或是美偶然留下的虚情假意，在未认识美之前，人们只能被动地接受美，这时也只有这点具体的美才算是真实可靠的，也只有它还保留着一份探求美的可知性的希望，也意谓着对它的研究必然会有一个具体的结果。

adopting the method of demography and historical georgraphy,andon the basis of the administravie division of county and an imaginary fu,this article reconstructs china's abnormal death roll during the period of 1959-1961, which amounts to 32,500thousand.and we will find a great negative correlationbetween the death roll of 1959-1961and that of 1851-1875.this article believesthat,it is not the average resources and food in different regions,but the folk"historical memory"about famine that leads to this special result.

内容 摘要：本文采用人口学和历史地理学的方法，以县级政区为基础，以虚拟的&府&级政区为单位，重建1959-1961年中国各地非正常死亡人口数。计算结果表明，1959-1961年中国的非正常死亡人口多达3250万。将1959-1961年的分府死亡人口与1851-1875年的分府死人口进行对比，可知两个时代的人口非正常死亡呈强负相关。本文认为，造成这一奇特结果的原因在于民间关于饥荒的&历史记忆&，而与各个区域人均拥有的资源及粮食无关。

The analysis result shows that the basement fault anomalies control a few major large hidden batholiths and their associated orefieldsthat the anomalies of cover structure confine most Cu-Au deposits and Fe-Cu deposits within their scopethat the geochemical anomalies and lithofacies-paleogeographical anomalies are major geological factors leading to trataboundness of some Cu-Au depositsthat the anomalies of rock operties provide the favorable chemical and physical conditions for the ore-forming process, including the seepage, circulation,convergence and deposit of ore-bearing hydrothermal solutionthat the anomalous ctive stage of Mesozoic magmatite is almost consistent with the major mineralization epoch of the Fe,Cu deposits, and the structure of multi-levels,and the zoning in magmatic system determine the spatial distribution of the mineralization system.

由分析可知基底断裂异常控制了本区若干重要规模较大的隐伏岩基及伴生矿田，而盖层构造异常控制铜金矿床和铁铜矿床的空间位置地层的地球化学异常和岩相古地理异常是造成一些铜金矿床层控性的主要地质因素盖层的岩性异常为含矿热液的渗流、循环、聚集和矿质沉淀等一系列成矿作用提供了有利的物理和化学条件中生代岩浆岩的异常活动期也是本区主要的铁铜成矿期，岩浆岩系统的多层分枝和分带性结构控制了本区成矿系统的三维空间分布。

通过测定DMIR反应系统中的固定化糖化酶的表观动力学参数可知，其表观米氏常数分别为游离酶的米氏常数的2.845倍和固定化酶本征米氏常数的1.39倍，最大反应速度分别是上述二者的0.189倍和0.335倍；而与间歇搅拌反应罐系统中的动力学参数相比较，DMIR中测得的表观米氏常数和最大反应速度分别是间歇搅拌反应罐系统下的0.55倍和4.82倍。

According to the experimental results, both the conducting area and material of current collector slices have great influence on the performance of micro PEMFC, especially the former one. The increment of cell's performance is finite by increasing the gas reheats temperature. The performance is better for open ratio 75% compared with 50% and 67%. The concentration polarization is improved by increasing the air flow rate at high current density and if the GDL diffusive capability in the latter cell could be promoted, the differences between these two cells' performances would be reduced.

由实验结果可知，集电片的导电面积与材料对於电池性能有显著的影响，尤其是前者；对於增加反应气体的再热温度，微型燃料电池增加的性能有限；双极板开孔率75%相较於开孔率为50%与67%有最佳的性能曲线；增加阴极气体空气的流量，可以改善高电流情况下的浓度极化现象，所以若我们能增加气体扩散层的扩散能力，则可以减少两者的性能差距。

In comparison of news professional labor with other ones, it can be found that news ethics is paid more attention to though it comes into being late, that it is greatly influenced by the morality of historians, and that it is applicable partly to pressmen of all kinds though wholly to those of some social class.

新闻道德既有一般职业道德的共性，又有其独特的个性，从新闻职业劳动的特点以及与其他职业的比较中可知：产生的时间晚、被关注的程度高、受&史德&的影响深以及普遍性与阶级性并存是新闻职业道德独具的特点

Features that remain constant throughout recorded language history are identical with language universals encountered in modern languages. Thus, we find changing inventories of phonemes but complete constancy in the basic phonematic mode of signaling. All languages are and have been phoneme-language throughout the documented past. Sound analogy or sound imitation is never encountered un-phonematized.

在历史的纪录中，恒定的特徵在所有语言中是普遍相同的，现代语言也不例外，因此我们发现音素的存留虽有改变，但是在发出信号的基本音位调式上是完全恒定的，由历史纪录可知，所有语言都是以音素为本的语言，声音的类比和声音的模仿永远都是音素化的。

According to the campus general satisfaction survey aimed at teachers and students of Dali Senior High School, Taichung County, ambient lighting of north/south-facing buildings is better than that of east/west-facing ones; old Fu-tien and You-cing Buildings are more superior to new buildings in ventilation and sound insulation. Most of the items about the general impression on campus reveal a higher satisfaction rate. 65.7% of the teachers and students agree to the statement that "I like my school as a whole."

在台中县立大里高中师生对整体校园满意度调查的具体成果为「南北向大楼的自然采光优於东西向」；「旧建筑的福田楼及友情楼在通风效果及隔音效果上均优於新建筑」；在校园整体感觉方面大部分项目满意的比例皆高於不满意的比例；「综合而言我喜欢我的学校」，同意的占65.7%，可知大部分师生对台中县立大里高中是能认同的。

The moon shines from the gloom to the fog which rise up with the moon shining afar singing love songs to the people guiding the setting moon unexpected sorrow for this Singing the night feel sad Spring River Tiber, who lifts as Reed transpiration of water vapor in the search for tomorrow's dinner one person dinner only accompanied by an eating moon's bed watching for the moon also could not help feeling so sometimes on the road we can see the moon and talk I youth under short-term impact on the beautiful quiet now because it is lonely depressed mood, I often like the moon phases as turbulent as Tide or I may be bleak moon children....

月亮闪亮著从沉沉的雾气中升起来月亮闪亮著为远方唱著情歌的人指路残月生出的忧伤让今晚歌唱的人备感伤心月夜泛舟的人撩开芦苇在水气蒸腾中找寻明天的晚餐一个人的晚餐只有陪著月亮吃了一个人的床让月亮看著也有些惋惜所以禁不住有时就对著月亮倾诉心事可知我的青春短暂月影下美好的宁静现在因孤单却令人惆怅我的情绪常如月亮的圆缺如潮汐般汹涌或暗淡我也许是月亮的孩子。。。。
