State variables at left end of time interval and costate at right end of time interval were taken as independent mixed variables, and the state and costate variables inside the time interval were approximated by Lagrange interpolation. Nonlinear optimal control problems were replaced by nonlinear equations through dual variable principle, and the symplectic algorithm for solving nonlinear optimal control problems can be obtained at the same time.

以时间区段一端状态和另一端协态作为混合独立变量，在时间区段内采用拉格朗日插值近似状态变量与协态变量，然后利用对偶变量变分原理并将非线性最优控制问题转化为非线性方程组的求解，最终得到求解非线性动力学系统最优控制问题的保辛数值方法。

Our results showed that 1, 8-Naphthyl imide could improve the properties of natural oligonucleotide in resisting nuclease and binding the targeted sequence by covalently linkage at the end of oligonucleotide. Moreover, our results also showed that the antigene oligonucleotide could specifically cleave the targeted double DNA sequence by modification of naphthyl imide at the 3'end of oligonucleotide.

体外结果表明萘二酰亚胺对寡核苷酸的共价修饰可以提高天然寡核苷酸抗核酸酶降解能力，提高寡核苷酸与靶序列结合的稳定性以及使寡核苷酸具有选择性结合和切断靶DNA的功能。

Secondly, we choose the proportion of shares held by institutions as dependent variable, and we use log of the total asset, volatility, beta, Jensen Index, debt-to-asset ratio, dividend yield, turnover ratio, years listed in exchange and HS300 Index dummy as explanatory variables. Then we set up a multiple regression model. Finally, we use the cross-sectional data from the end of 2006 to the end of 2007Q3 to test the relationship between the explanatory variables and the proportion held by institutions.

具体方法如下：首先，在已有研究成果的基础上，对我国机构投资者的审慎性持股偏好提出了两个假设；其次，以机构持股占个股流通盘的比例为因变量，以公司的总资产对数值、波动率、贝塔值、Jensen指标、资产负债率、股息率、年度换手率、上市年限为解释变量，并在引入沪深300虚拟变量后，建立了多元线性回归模型；最后，采用我国证券市场迎来历史性大牛市、机构投资者发展最为迅猛的2006年末-2007年3季末的四个横截面数据，对各解释变量与机构持股比例之间的关系进行了实证检验。

Part three: An experiment study on the repair of peripheral nerve injury by NT-3 gene modified neural stem cells objective To investigate the effective treatment of peripheral nerve injury with NT-3 gene modified neural stem cells, to explore the feasibility of the treatment by means of gene transfection Methods 54 SD rats were divided evenly into 3 groups. The sciatic nerve transected model were made and sutured end to end with epineurium. The neural stem cell without NT-3 gene or with NT-3 gene modified were injected into triceps muscle one time a week, saline injected as control group. The nerve trunks of stomas and triceps muscle were acted as specimen three weeks、six weeks and nine weeks after operation.

Posada admitted by the end of last year some hitters were sitting too much on Wang's sinker, and that, combined with whatever drop his bread-and-butter pitch lost by the end of last year, made Wang more hittable, not just very predictable.

小波承认在上个赛季的最后，一些打者锁定了小王的伸卡球，这使以伸卡球为主的小王输掉了上赛季最后的比赛，更多的球种也使小王更耐操，不会简单的被猜中。

Picker-wheel support structure was used in strip label papers of tobacco industry, but it had appeared some problems: picker-wheel vibrates easily, label paper was picked insecurely, and double-shafts generated deformation and linear bearings wear easily. The ultimate cause was founded by analyzing linear bearings stress from statics and dynamics. The original structure of double-shafts one-side support was replaced by two-side support with one fixed end and one free end.

针对FOCKE350S条盒商标纸拾取轮总成支撑结构拾取轮易振动、商标纸拾取不可靠、双轴易弯曲变形、直线轴承磨损快的情况，从静力学和动力学的角度分析了直线轴承磨损快的根本原因；并将原来双轴单侧支撑结构改为双轴双侧支撑，采用一端固定，一端游动的支撑方式。

This ain't a love song 歌手:bon jovi this ain't a love song bon jovi i should have seen it coming when roses died should have seen the end of summer in your eyes i should have listened when you said good night you really meant good bye baby, ain't it funny, how you never ever learn to fall you're really on your knees, when you think you're standing tall but only fools are "know-it-alls" and i played that fool for you i cried and i cried there were nights that died for you baby i tried and i tried to deny that your love drove me crazy, baby if the love that i got for you is gone if the river i cried ain't that long then i'm wrong, yeah i'm wrong, this ain't a love song baby, i thought you and me would stand the test of time like we got away with the perfect crime but we were just a legend in my mind i guess that i was blind remember those nights dancing at the masquerade the clowns wore smiles that wouldn't fade you and i were the renegades, some things never change it made me so mad 'cause i wanted it bad for us baby now it's so sad that whatever we had, ain't worth saving if the love that i got for you is gone if the river i've cried ain't that long then i'm wrong, yes i'm wrong, this ain't a love song if the pain that i'm feeling so strong is the reason that i'm holding on then i'm wrong, yeah i'm wrong - this ain't a love song i cried and i cried there were nights that i died for you baby i tried and i tried to deny that your love drove me crazy baby if the love that i got for you is gone if the river i cried ain't that long then i'm wrong, yeah i'm wrong - this ain't no love song if the pain that i'm feeling so strong is the reason that i'm holding on then i'm wrong, yeah i'm wrong - this ain't a love song by lune the end JTL 很长时间Love Is A Pain (I don't cry)(I don't cry)(I don't cry)(I don't say) As time gose by

你身边的那个人看起来会比我做得更好放你离开的那个冬天，痛苦了好久，但是都没有用了开始我小心地走向你，你用阳光般的微笑接受了我的心那么想见你，落下了泪，但是（I don't cry）现在什么也无法说想说爱你，现在不再是我的你有的时候给我的问候的电话我说现在过得很好这样的话，但舌头无法像以前看到了我变瘦的样子，你也会吃惊放你离开的那个冬天，痛苦了好久，但是都没有用了开始我小心地走向你，你用阳光般的微笑接受了我的心那么想见你，落下了泪，但是（I don't cry）现在什么也无法说想说爱你，但现在不再是我的你如果对我说你回来吧我会再次抱着你如果只想看我一次，我会把空位子留给你说不定那个时候是我们两个再一次没有办法地擦肩而过的命运我这样疼痛，你也会非常疼痛的，那个时候你也说没有办法我的没有用的自尊心非常非常的后悔没有你，度过了很长时间，只一个人没有你，我忍受着，得生活下去，我没有自信那么想见你，落下了泪，但是（I don't cry）现在什么也无法说想说爱你，我想再见到你，但现在好象一切都结束了希望好久以来积攒的记忆，到什么时候都不会在时间里被埋没祝你幸福

The plastic go down the hopper smoothly and is gripped by the thread of the screw. It is forced to go toward the direction of the gear end along with the rotation of the screw. A mechanical transferring process is formed. During the running of the plastic from the feed port to gear end, a high pressure is formed in the process of plastic curing due to the gradual decreasing of the thread depth and the resistance of filter gauze, splitter plate and gear end. The high pressure helps to press the raw material and improve its heat conductivity performance and the quick melting of the plastic, at the same time, the gradual increasing pressure can help the gas which is among material particles exhausted from the air holes.

在压力升高的同时，塑料一方面被外部加热，另一方面塑料本身在压缩、剪切、搅拌的运动过程中，由于内磨擦力也产生了大量的热，在外力和内力的联合作用下，塑料温度逐渐增高，其物理状态也经历了玻璃态--高弹态--粘流态的变化，一般地说来，在加料段中主要是玻璃态，在螺杆螺纹逐渐减少的中间部分压缩段中，物料主要处于高弹状态，同时也逐渐的熔融，而物料到压缩段后部和化段作用处于粘流态了，这时我们称塑料已完全塑化了，由螺杆推力作用将塑化的塑料定压定量的从机头中挤出。
