To summarize molecular, morphology, chromosome and pollen characters, the conclusion was reached that Epimedium was an nd monophyletic taxon. To divide the genus into any groups would be artificial. It is proposed that the disjunction by space, climate and seas were the main reason of respectively differentiation of each group by the view of geographic and climate changes in the temperate zone of the world. Because of its evolution-conservation, the disjunction did not bring about obvious divergence on the level of molecular and morphology.

综合分子特征和形态、细胞学、孢粉学等性状，提出淫羊藿属是一个进化上极为保守的、自然的单系的植物类群，进行属下任何阶元的划分都将是人为的，从旧世界温带的地质变化及气候变迁的角度推测，空间、气候和海洋的隔离是产生类群各自分化的主要原因，但由于其进化上极度保守，这些隔离尚未产生出类群间形态上和分子水平上的明显趋异。

The whole PWM circuit contains two subcircuit, the front-end is PWM module that make up of the counter that based on nine MOSFET True-Single-Phase-Clock D flip-flop; the back-end is demodulated module, which is consist of a three order Chebyshev low-pass filter used trans-conductor capacitor. All the subcircuits are simulated. At last, an approving simulated result of the whole circuit is given too.

在调制部分，利用九管单相时钟D触发器构成计数器，并由此组成了脉冲宽度调制电路，同时给出了在典型温度下的仿真结果；在解调部分，介绍了低通滤波器从无源到有源的设计方法，设计了三阶切比雪夫低通跨导电容滤波器，同样给出了相应的仿真结果；最后，作为将脉冲宽度调制电路和滤波器作为整体电路，以脉冲调频波为输入进行了仿真，取得了令人满意的结果。

In this paper, four sections located respectively in Yadong-ZhergerLa in central Himalaya, Pai-Zaqu reach of Yalung-Tsangpo River, west slope section of NamuLa and east slope section of DuoxiongLa in Eastern Himalaya Syntaxis were chosen, and conventional and laser ~(40)Ar/~(39)Ar methods were used to build the framework of thermal evolution history of central-east part of Himalaya orogen, for the purpose of revealing the secret of uplif of central-east Himalaya.In Yadong district in central Himalaya, a retro-metamorphic high-pressure granulite and its country rock were focused and conventional ~(40)Ar/~(39)Ar tests were done.
