By using the animalcule experimental technology, we have, on one hand, confirmed the better methods of MIC of camphor and on the other, ascertained that calyx canthus oil can work through immunity adjusting rather than anti-epiphyte.

加上当时课业和GT备考的压力也比较大，所以在之后的很长一段时间里都没能学到什么实际的研究经验，只是对实验室的几个主要研究方向有了初步的了解。

According to the change of the enemy\'s quantity and the qualitative theory of the differential equation, we research the spruce aphides and its predator system. At the same time, we discussion the spruce aphid multiplication model when the natural enemy quantity is a certain value and the periodic oscillating model whose the quantity of the natural enemy changes along with the time. Obtains the stability condition of the balance point and the limit-cycle existing condition, the system presents the dissipative structure\'s character. Finally it explains that this theoretical analysis has certain practical significance regarding the preventing and controlling harmful insect.

第五章，松毛虫与其天敌的关系是食饵和捕食者的关系，根据天敌数量的变化，利用微分方程定性理论，研究松毛虫与天敌系统，讨论天敌数量为一定时的松毛虫增殖模型和天敌数量随时间变化的周期振荡模型，得到正平衡点全局稳定性和极限环的存在条件，通过计算机模拟，说明周期振荡的捕食模型能够呈现典型的时间耗散结构特征，对于防治害虫有一定的实际意义。

As the impact of time, current parameters such as number of factors, thus indicating the valve opening angle and the actual location is not easy to achieve synchronization, often apparent error.

由于影响时间、电流等参数的因素很多，因此显示的开启角度与阀门的实际位置不易达到同步，经常出现明显的误差。

Model RWM within the ARSIS concept (Ranchin and Wald 1999) and the P+XS algorithm (Anonymous 1986). A comparison of the synthesised images demonstrates the possible misinterpretation that can result from an non-appropriated method. A quantitative assessment is then performed of the synthesised images. These two comparisons enhance the quality of the method derived from the ARSIS concept.

RWM-ARSIS 方法(Ranchin and Wald，1999)和 P+XS 算法[1](Anonymous 1986)对三峡工程三斗坪大坝区的多时相高空间分辨率的SPOT图像(获取时间为1990，1997和1998年，包括全波段P图像和多波段XS图像)进行融合处理，在提取测区地面动态变化信息的同时，从理论和实际应用的角度探讨了不同数据融合方法的效果。

Using real data from a seismic exploration, we achieved the migration sections of converted wave beneath volcanic area, and it is proved that the method is effective for computing common asymptotic conversion point and pre-stack time migration.

实际资料的成像结果表明，本文采用的近似转换点计算以及转换波叠前时间偏移方法是有效的。

Simplier and more efficient ion extraction methods for atomic vapor laser isotope separation AVLIS were evaluated using a 2-D electron-equilibrium model to compute and compare three electrostatic methods the parallel electrode method, the Π type electrode method, and the improved M type electrode method.

为探索用于原子蒸气激光同位素分离AVLIS的简单有效的离子引出方法，用二维流体理论电子平衡模型计算比较了3种静电场方法平行板电场法，Π型电极法，改进M型电极法计算发现，二维流体理论电子平衡模型并不能很好地描述Π型电极法对另外两种静电场方法，计算了不同外加电压、不同的初始原子密度和不同的目标同位素丰度等条件下的离子引出情况从计算结果可以看出，改进M型电极法不论是从离子引出时间还是从碰撞损失率，都要比平行板电极法好得多当外加电压较高或初始原子密度较高时，这种好处就更加明显因此，改进M型电极法是一种可供实际采用的比较好的静电场方法

In every policy, there must be some security authentication information,such as one policy Authorizer, one Licensee, one TimeStamp, one LifeTime and a digital Signature, and some policy management information:At last, this paper designs and implements a HywaveGuard models instance based on Windows OS.

每个策略都有策略发布者，接受者的证书，策略制定的时间戳及有效期，同时还要附上发布者的数字签名，这些信息用于保证策略的安全验证；每个策略还可包含策略管理命令及策略内容，这些信息用于保证有效的策略管理与节点间通信。最后，针对当前网络的实际情况，本文在Windows系统平台上设计与实现了HywaveGuard防火墙模型的一个实例。

In the whole process of the work, one step was linked with another closely, and no rubbish data were created, the procession of calculating coefficients and of outputting the final map realized autoimmunization, saved much time, improved the precision of the classification, and the outcome of the classification objectively reflect the local fact of Liwu county.

在整个工作过程中，各环节步步相扣，不产生垃圾数据，参数计算和成果图的输出实现了自动化，节约了时间，提高了精度，等别划分的结果客观准确的反映了当地的实际情况。

Although the Preissman scheme of KP equation is multisymplectic, it took too efforts to realize, Hence we elimate the auxiliary variable by a trivial computation and obtained the multisymplectic forty-five points scheme of KP equation. And then, we test this forty-five points scheme on soliton and solitary waves over long time intervals, the numerical results shows the propagation and interact of soliton and solitary waves.

但是在实际的数值实验中，由于需要计算共轭动量的值，Preissman格式需要占用的计算内存比较大，计算时间比较长，因此我们在数值格式中消去共轭动量，最后得到与多辛Preissman格式等价的一个多辛45点格式，我们用这个格式进行了数值实验，数值实验结果很好地显示了孤立子和孤立波的传播与碰撞。

Seemingly technical questions related to the form of the tax, exemptions, rates, and timing turn out to be bound up intricately with the normative principles at stake.

表面看来，技术问题涉及税收、豁免、税率、时间选择等形式，实际却是与危如累卵的标准化原则有着密切关系。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
