Generation of Nonlinear Force Driven Blocks from Skin Layer Interaction of Petawatt-Picosecond Laser Pulses for ICF

The discovery of the essential difference of maximum ion energy for TW-pslaser plasma interaction compared with, the 100 ns laser pulses led to the theory of a skin layermodel where the control of prepulses suppressed the usual relativistic self-focusing. The subsequentgeneration of two nonlinear force driven blocks has been demonstrated experimentally and inextensive numerical studies where one block moves against the laser light and the other block intothe irradiated target. These blocks of nearly solid state density DT plasma correspond to ion beamcurrent densities exceeding 10^(10) A/cm^2 where the ion velocity can be chosen up to highlyrelativistic values. Using the results of the expected ignition of DT fuel by light ion beams, aself-sustained fusion reaction front may be generated even into uncompressed solid DT fuel similarto the Nuckolls-Wood scheme where 10 kJ laser pulses produce 100 MJ fusion energy. This new andsimplified scheme of laser-ICF needs and optimisation of the involved parameters.

The Dynamic Simulation of Rotary Inertia on Light vehicle-Slope I

According to formula we can simulate their driven force and acceleration on the slope.The mechanical formula is used to obtain force and theoretical dynamics in the slope.The driven force decreases when rotation increases.When power increases the acceleration increases.it reduces when its weight raises.It is found that the a will decrease as slope becomes high from 5 to 11°to 22°,which fit the formula too.Meantime as the radius is high from 0.3m to 0.4m to 0.47m a will be low.The needed force will increase as the slope decline becomes big at the same power.

The Simulation on Dynamic of Rotary Inertia and Engine’s Inflamer in Light Vehicle

According to formula we can simulate their driven force and acceleration.The mechanical formula is used to obtain dynamics is used to simulate.The driven force increases when torque increases and tire diameter decreases.We need torque to increase so this is our plan.Acceleration raises when torque raises and it reduces when its weight raises.With the decreasing of radius of road the centripetal acceleration is increasing in the condition of light vehicle.It is that it decreases sluggishly before 0.35m/s2 then it maintains a steep decline to 0.62m/s2 and at last becomes sluggish again.It is valued that the economical efficiency about consumed fuel under different power.In the time of 0.2hr the fuel inflamer inclines sharply first then turns stable.It is the smallest value.Beyond it the fuel maintains a high value all the time.The discharged pollution gas decreases with the decreasing initial temperature.The low initial temperature is good to fuel gas.Meantime the smallest incline range is 300~350K which explains that it is the most save one.

The Simulation of Dynamics and Consumed Fuel on Rotary Inertia of Vehicle

According to formula we can simulate the driven force and acceleration of a car.The mechanical formula is used to obtain torque value and theory dynamics is used to driven force.The driven force increases when torque increases and tire diameter decreases.Torque increases when power increases and rotation decreases.Acceleration raises when torque raises and it reduces when its weight raises.It is valued that the economical efficiency about consumed fuel under different power.9 times of efficiency promotion are attained before vehicle arrives 0.5 h,on the other hand 2 times of little efficiency promotion has been attained in driving time between 0.5 h and 1 h even after 1 h.

Atomic dispersion of bulk/nano metals to atomic-sites catalysts and their application in thermal catalysis

Supported metal-group materials are commonly utilized as state-of-the-art catalysts in industry.Atomic-sites catalysts(ASCs)have attracted increasing attention in catalysis owing to their 100%atom efficiency and unique catalytic performances toward various reactions.In particular,atomic dispersion of bulk and nano metals has become the focus of research and development in the synthesis of ASCs.Over the past decade,burgeoning interests have been paid to atomic dispersion in ASCs and their applications in catalysis.However,to the best of our knowledge,the systematic summary and analysis of atomic dispersion were rarely reported.In this review,recently developed ASCs by atomic dispersion were discussed in terms of synthetic atmosphere,driving force,applications in thermal catalytic reactions.Perspectives related to challenges and directions as well as design strategies of ASCs in atomic dispersion were also provided.

4100万年印度季风增强和扩张的古地理控制

印度季风是亚洲季风的主要水汽来源.但截至目前我们对印度季风的形成演化和内在驱动机制的理解仍十分有限.有关印度季风新生代早期形成的报道均在热带季风区,受控于赤道辐合带的季节摆动,而与青藏高原隆起无关.然而,此区以外准确定年的印度季风记录对于揭示印度季风如何扩展并了解其驱动因素至关重要.位于亚热带云南的古环境记录揭示始新世早期的干旱气候环境在4100万年时突变为季节性湿润环境,指示印度季风在4100万年时已到该区.综合集成分析认为印度与亚洲板块的完全碰撞及其导致的古地理巨变(新特提斯海关闭、副特提斯海急退、高原南部边界快速北移和高原中部隆升),可能共同推动了印度季风在约4100万年时的增强和向北扩展.
