The CVD is an important index to indicate tree diameterdifferentiating.On basis of dynamic change and tendency of CVDamong trees in stand,three models of square CVD are proposed.i.e.,basic model,stand factor model,and thinning effects model.All threemodels are of mechanism,asymptotic characteristic,and invariance forprojection length.Futhermore,there are compatiability and extremevalues in thinning effects model for thinned and unthinned stands.

直径变动系数是描述林木直径分化的重要指标，根据林木直径变动系数的动态变化和趋势，本文提出了直径变动系数平方动态变化的三个模型：基本模型，与林分因子相关的模型，考虑间伐效应的模型，上述三个模型均具有一定的机理性、渐近性和步长不变性，特别是考虑间伐效应的模型为间伐林分和未间伐林分的相容性模型，它还具有相容性和极值性。

Since we are concerned primarily with the future,it would be better to take no notice of tradition.

文章主要讲了人类的发展离不开变化，传统在变化的世界中有正反两方面的作用，而较好的做法是接受传统所提供的帮助，同时要认识到它的局限性。

In the process of immigration of eastern Sichuan and western Hubei, at least three issues are worthy of noting: one, the settlers had a difficult trip, life was unstable and crafts was extremely difficult in the mountain region in early time; two, Land disputes are more common in initial time of immigration, occupying boundary, subleasing, reselling and looting land often caused fights even murder, which shows early highly complex relation of immigration in community; three, immigrants plays a very important role in the development of local economy. If the local economic development can be divided into four stages, the fourth period (that is, from the middle of the 18th century to the 19th century) is the most important period for immigration, is the period of fastest development of economy and is the period of the local economic development the largest impacted by immigrants.

初期移民社会至少有三个问题引起本文注意，首先、移民们行程艰难，到达深山地区初期的生活很不稳定，劳作极其艰辛；其次、土地纠纷是初期移民社会较为普遍的现象，蒙混占界、转租转卖、抢占土地往往引起群殴甚至酿成命案，初期移民社会围绕土地争夺而展开的各种关系极为复杂；三、移民给当地社会经济带来了较大的变化，如果可以将唐宋至十九世纪末当地经济的发展分为四个时期，那么，第三个时期(即十八世纪中叶到十九世纪)是移民的重要时期也是当地经济发展最快的时期，移民对经济发展变化的影响是很大的。

In the whole growth period of spring wheat, the response was different in yield and phase growing on climate change, such as the appearing time of sprouting, jointing, tasselling and maturity being ahead but milking being postponed. That is to say, it shortened the spring wheat's nutrition growth stage of seedingsprouting, elongated the sproutingjointing stage, cut down the generative growth in the jointingtasselling phase, prolonged the tassellingmilking stage, and shortened the milking~maturity stage. These finally resulted in the shortening of whole growth period.

在春小麦整个生长发育过程中，其阶段生长和产量对气候变化的响应不完全一致：气候变化使该地区春小麦出苗期、拔节期、抽穗期和成熟期的出现时间均提前，而乳熟期出现时间推迟，导致播种—出苗期的营养生长阶段缩短、出苗—拔节期的营养生长阶段延长、拔节—抽穗期的生殖生长阶段缩短，抽穗—乳熟期的生殖生长阶段延长，乳熟—成熟期的生殖生长阶段缩短，最终造成全生长期缩短。

在春小麦整个生长发育过程中，其阶段生长和产量对气候变化的响应不完全一致：气候变化使该地区春小麦出苗期、拔节期、抽穗期和成熟期的出现时间均提前，而乳熟期出现时间推迟，导致播种－出苗期的营养生长阶段缩短、出苗－拔节期的营养生长阶段延长、拔节－抽穗期的生殖生长阶段缩短，抽穗－乳熟期的生殖生长阶段延长，乳熟－成熟期的生殖生长阶段缩短，最终造成全生长期缩短。

These influences include altered neurodevelopment of the brain, cognition, and behaviour; exacerbation of the comorbidities due to decades of medically intractable epilepsy; and possible acceleration of common age-associated changes, leading to uncertain and understudied outcome in old age.

这些影响包括大脑、认知和行为的神经发育的变化；长期难治性癫痫引起的并存症的恶化；可能的年龄相关的常见变化的加速，导致了年老时的不明确的后果。

For the problem of the ratio of inner to outer diameter of long tube, according to the "residual core" in the target plays an important role in DOP of long tube penetrator, the analytical model of long tube pentration in semi-infinite homogeneous steel target is established and calculated to devide three kinds of different scopes, the rule of varied by the ratio of inner to outer diameter is analyzed. The patterns of penetration of the yawed tubular against a normal homogeneous semi-infinite target is established, the size and direction of "residual core" is analyzed, under the different impact yawed, the regularity of variations in the yawed of the tube and depth of the penetrateion is described during the penetrateion against the plate.

The average linewidth enhancement is the latent physical attribute of SOA that is the groundwork to investigate the OSP based on cross phase modulation of SOA.

平均线宽增强因子是SOA的本征物理属性，它不随输入信号的改变而改变，而器件有效线宽增强因子则是系统相关的，它决定了脉冲的相位变化和增益变化的关联度，是研究基于SOA相位调制效应的光信号处理问题的基础。

This paper presents a wind vane sensors without the use of cases, combining with gyroscopes and hill-climbing algorithm to control the yaw institutions, can accurately capture the wind direction signal, rapid-conditioning the cabin of the deflection angle, so that wind generators wind wheel normal direction of the wind direction and change is always consistent for maximum capture of wind energy control strategies.

针对风力发电机组的风向变化绝对值小于15°的风能捕获率问题，提出一种在不使用风向标传感器的情况下，采用陀螺仪和爬山算法相结合的方法来控制偏航机构，能够准确的采集到风向信号，快速调节机舱的偏转角度，使风力发电机风轮法线方向与变化的风向始终保持一致，实现最大捕获风能的控制策略。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
