The article first theoretically analyzes the principle that microcavity reduces threshold 、changes resonant modes of output light and enhances unidirection of the random laser.Then study the structure parameters of different microcavity by transfer matrix.Based on the theory of Maxwell equations and the rate equations, analyze the principle that microcavity reduces the threshold by FDTD method: Changing the confined position,reducing relaxation time and increasing reversing particles, also simultaneously study the influences of the threshold and output light modes by different microcavities and random intensity of random medium.

首先从理论上分析了利用微腔降低随机激光器阈值、改变出射光振荡模式、提高出射光准直性的原理，然后利用传输矩阵法模拟研究了不同的微腔应具有的结构参数，最后以麦克斯韦方程和速率方程理论为基础，利用时域有限差分法分析了利用微腔降低阈值的原理：改变局域化位置、缩短弛豫时间及增大粒子数反转，同时也模拟研究了微腔、随机介质的随机强度对阈值及出射光波模式的影响。

Instead of a "moment" of change, China needs structural and long-term reforms: placing the Communist Party under the rule of law, unshackling the media and Internet, allowing religious adherents to freely practice their faiths, ceasing harassment of civil-society groups that work on AIDS and the environment, and addressing modest calls for accountability in the political system.

而不是&瞬间&的改变，中国社会需要结构性的和长期的改良：将中国共产党的地位置於法律之下，恢复媒体和互联网自由，允许信教徒能够自由地践行他们的宗教信仰，停止对防治艾滋病和环境保护社会团体的管制，建立一种更加谦和的政治体制。

The objective of Echo company is to meet up with these men that have been dropped off at a single LZ. These 5 dropped technicians will turn the colour of the first arriving player and will change controls. Once escorting these men to the hangar within the airfield is finished, these airdropped units will activate a truck and get in. Once these men are into a truck, the truck will change control to AI, and will begin following the player who had 'rescued' them.

回声小组的目标是接触这些被空降在一个降落地区的人员，这5个被空降的技术人员将会将颜色改变为第一个到达他们位置的玩家颜色并将控制权交给该玩家，一旦成功护送这些人员到达机场，他们将会启动并登上一辆卡车，卡车的控制权将会交给AI，并且卡车将会跟随&拯救&了这些人员的玩家。

The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.

并且得出，每个树种在树冠内相对高度上的叶量的垂直分布是不同的，天然次生林阔叶树种的叶量在树冠的上部(0.3CL以下)所占比例很小，约占10%左右；在树冠的中部以及中下部(0.4CL～0.8CL)，叶量所占比例最大，几乎集中了整个树冠60%～75%的叶量；而在树冠的下部(0.8CL以下)，几乎占很少的叶量，大约10%左右。5、采用Hegyi竞争指数来表现次生林内林木的竞争关系，并且根据竞争圈的大小和林木在竞争圈内的分布位置、大小与距离来计算有效的竞争木，并不是传统意义上的全部竞争木；本研究提出用树冠叠加指数来表示林木与周围树木的树冠竞争情况，并采用等树冠投影面积法把树冠分为5级，这样计算的树冠叠加指数更加与现实林分相符。6、本研究基于乘除法的思想，用多样性混交度、聚集指数、竞争指数和树冠叠加指数构建了天然次生林择伐空间优化模型，设计了10个与林学意义相一致的约束条件，并采用0-1整数规划的思路，在LINGO9.0软件中使用了隐枚举法对目标函数求得最优解。7、以M702标准地为应用实例，具体计算出了每株采伐木，经过择伐后，目标函数值按模型设计的要求发生了极大的改变，增加了5倍多，说明了最后这个解的优良性，满足了设计的要求。

In order to investigate whether the lysine 188 residue in the XRCC4 is chemically modified by the enzyme SIRT2 or not, I apply site-directed mutagenesis to alter this lysine to either arginine or glutamine, which mimicking the non-acetylating or fully acetylating of lysine residue.
