But after about a month to restore the root system, the leaves of nitrogen, phosphorus and potassium contents in treatment 5, 6, 7, 8, 2 gradually higher than the control. This is because the absorption of fertilizer during this period shown to promote on the elements, and with the passage of time the processing elements continue to be reduced to a leaf until the latter part of the growing season is also higher than the control.3.The pH value in rhizosphere soil of treatments poplar plantation were lower than that in non-rhizosphere soil, but the content of organic,available nitrogen, phosphorus, potassium, utility cuprum and utility zincum were all higher than those in non-rhizosphere soil.

但是经过大约一个月的根系恢复，处理5、处理6、处理7、处理8、处理2叶片中的N、P、K逐渐高于对照，这是因为施肥对元素的吸收在这一期间开始表现出了促进作用，并且随着时间的推移各处理中元素含量持续降低至落叶，直至后期的生长季节也高于对照。3、各处理的杨树林地根际土壤pH值均低于非根际土壤，而有机质、碱解氮、速效磷、速效钾、有效铜和有效锌的含量均高于非根际土壤，与其它处理相比，80cm两侧断根施肥处理的根际土和非根际土壤速效养分含量最高，差异达显著水平。

To settle the problem, this article brings about a hybrid algorithm by combining the mean shift and the particle filter tracking technique on the basis of the color histogram distribution. By adopting the strategy that the number of particles is adaptively determined, it amalgamates the virtues of the two techniques. It reduces the computational cost and ensures the performance simultaneously.

该文基于颜色直方图分布，引入自适应选择粒子样本数的采样策略，有效地融合传统Mean shift算法的简单快速和粒子滤波跟踪算法的抗遮挡的优点，在保证跟踪效果的同时减少了跟踪的总体时间花费，有效提高了设计的跟踪系统的实时性。

In addition to mapping the connection pattern among the 100 billion-or-so neurons, the scan would probably also have to register some of the functional properties of each of the synaptic interconnections, such as the efficacy of the connection and how stable it is over time (e.g. whether it is short-term or long-term potentiated).

除了描绘1000亿左右个神经元的连接模型，扫描过程可能还必须得记录每一个突触互联的一些功能特性，如连接的效率和它稳定所需的时间（例如，连接是短期有效还是长期有效）。

The motion scope judgement search method based prognosticating the search beginning point, it utilizes the time relativity and the space relativity of block to prognosticate the search beginning point, and adopts the different search pattern according to the block motion scope, the search efficiency is close to the Three Step Search, which proves the feasibility of researching the new efficient motion estimation algorithm according to the characteristic of block motion to use the different search methods; In the end, this paper evaluates the advantage and disadvantage of the different fast algorithms through the data get from the experiment, it will have some reference value to bringing the new and effective motion estimation fast algorithm in the later research.

基于预测起点的运动幅度判断搜索法，该算法利用块的时间相关性和空间相关性来预测搜索起点，根据块的运动幅度大小分别采用不同步长的搜索策略，搜索效率比较接近三步法，证明了根据块运动的特性以结合运用不同的搜索算法来研究有效的运动估计算法的可行性。最后本文通过实验得来的数据来定量地分析评价各快速算法的优缺点，对今后提出新的更有效的运动估计快速算法具有一定的参考价值。

The efficiency and its indurability of the wrinkle alleviation was investigated.resultsamong all the cases, the efficient rate reached 100%,of which 74% are perfect results.the mean efficency indurability was 6～7 months.conclusionlocal botulinum toxin a injection is proved to be a effective method in the treatment of upper facial dynamic winkles.

结果：1周后返院复诊患者126例，93例显效，33例有效，治疗有效率100%，平均维持时间为6～7个月。结论：a型肉毒毒素注射用于治疗面上部动力性皱纹安全有效，但应严格掌握适应证。

The fuzzy T-S model was much more precise than the neural network model for burning through point based on process parameters. The rise time and regulating time of the fuzzy predictive control method were respectively 9 min and 18 min which were both much shorter than those by using the fuzzy control method for burning through point in lead-zinc sintering process.

结果表明：模糊T-S模型能有效抑制垂直燃烧速度不确定性的影响，具有较高的辨识精度，能够满足工业现场生产指导的需要；此外，烧穿点的模糊预测控制方法比单纯的模糊控制调节时间短、超调量小，能快速有效地响应烧穿点的变化，具有一定的应用价值。

The research finally suggested that it is difficult to its follow-up check after collision , and write down all accident details in advance , the deck log will be recorded in detail , adopt stating with the shipowner unanimously in accident , various kinds of fact reports , if time and environment is permitted obtaining the information of the other ship , the endorsing of letter of commitment of responsible ship is required , as stated by the safety management rule of international marine stipulates , the shipowner is besides must manage her ship fleet to set up a set of safety system of feasible monitor procedure , and it will so as to ensure do effective risk management , in order to reduce the injury of humanlife and environment , it can accord with management the ship owner continued forever.

研究最后建议船舶碰撞后其真相追查不易，事先记下所有事故细节，航海日志均要详细记载，事故发生与船东采取一致陈述，各种事实报告，若时间、环境许可应取得对方船之资料，乃至碰撞责任承诺书之签注。国际海事安全管理规章规定，船东除必须为其管理船队建立一套可行安全作业流程外，更要建立一套有效之监督机制，以确保一切航海动态均在安全控管机制之下，做有效之风险管理，以降低人命与环境之伤害，方能符合船东永续之经营。

Degradable biomedical membrane is a biological barrier membrane, whose mechanism is to segregate the inflamed or trauma from the tissue and prevent the fibroblast inrushing the traumatic surface. And the controllable degradation time can assure the trauma of insulating until metaplasia. The membrane can effectively avoid the adhesion.

生物可降解医用膜作为生物屏障膜可有效防止术后粘连，其作用机理是将炎症或损伤部位与周围组织隔离开来，阻止周围组织中成纤维细胞对创面的入侵，而其降解时间的可控性能保证有效隔离直到损伤部位再上皮化，从而达到预防粘连形成的目的。

The prevention of human immunodeficiency virus is still no effective vaccine, antiviral therapy can not be effective to remove the virus from the body, and the existing HIV diagnostic kit to confirm the time required for longer, which is very expensive.

预防人类免疫缺陷病毒目前仍然没有有效的疫苗，抗病毒治疗也不能有效的将病毒从体内清除，并且现有的HIV确认试剂盒诊断所需的时间较长，价格昂贵。
