Movement trajectories of electrons under complex field and state parameters when electrons return to the dielectric surface are obtained by simulation,such as impact energy and return time. Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron,and there is an emergence angle in which the electron has the maximum trajectory length and impact energy.

研究发现：电子出射角度对其运动状态有显著影响，电子存在运动轨迹最大的某一出射角度，该角度下电子拥有最大的撞击能量；微波电场幅值的增加将使电子撞击能量增加，返回时间减小，微波电场相位的变化使电子的撞击能量和返回时间呈周期振荡，这从本质上解释了电子数量在二次电子倍增过程中以微波频率两倍周期振荡的原因；随着微波频率的增加电子将由简单的类抛物线运动转变为复杂的振荡运动。

Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron, and there is an emergence angle in which the electron has the maximum trajectory length and impact energy, Impact energy will increase and return time will reduce as increasing the amplitude of electric field, and both parameter would oscillate with the phase of electric field, which can essentially explain that multipactoring electron number oscillates in twice the frequency with the increase of microwave frequency, electron trajectory will change from parabolic-like movement to complex oscillation.

The biological characteristics and parameters for different geographic populations of Anastatus japonicus Ashmead in the eggs of Antherea pernyi were compared with the method of life table. The results show that the fecundity properties parameters of Vietnamese population including the net reproduction rate (R0), intrinsic rate of increase, finite rate of increase, doubling time, number of eggs laid per female, preoviposition period and oviposition period are superior to Guangxi, Guangdong and Hainan population.

应用生命表技术对荔蝽平腹小蜂Anastatus japonicus Ashmead不同地理种群以柞蚕卵为繁殖寄主的条件下的重要生物学指标和参数进行测定和比较，结果表明，越南种群的主要生殖力指标，包括净生殖力（R0）、内禀增长率、周限增长率、种群倍增时间、单雌产卵量、产卵前期和产卵历期均比广西、广东和海南种群的理想；4种群的雌蜂寿命、羽化率和雌性比率则没有显著差异。

实验中采用扫描法测量光斑的能量分布，通过柔性铰链机构带动微米级小孔以很小的步距对成像微光斑进行精确的二维扫描，用光电倍增管接收扫描采样的微弱光信号，再以低噪声的I/V转换电路和电压放大电路处理取样信号后送入计算机处理，就可准确地复原光斑的能量分布。

And we by the NDR curve of the IV curve can be observed, NDR device has a very special non-linear phenomenon, Usually composed of a non-linear circuit components are usually chaotic phenomenon, so we raise our six different structure in addition to the new frequency, and to explore the phenomenon of chaos, and the use of the cycle of chaotic phenomena in addition to the frequency multiplier effect achieved .

As gloomy as China's pollution picture looks today, it is set to get significantly worse, because China has come to rely mainly on energy-intensive heavy industry and urbanization to fuel economic growth. In 2000, a team of economists and energy specialists at the Development Research Center, part of the State Council, set out to gauge how much energy China would need over the ensuing 20 years to achieve the leadership's goal of quadrupling the size of the economy.

中国的污染图景已然灰暗无光，然而它却将朝更糟的方向发展，因为中国已经到了主要依赖高能源消耗重工业和城市化助燃经济增长的阶段。2000年，一组国务院发展研究中心的经济学家和能源专家，开始计算今后20年为达到领导层的经济总量4倍增长目标所需的能源消耗。
