可以解的

When the Hamiltonian system is introduced into the research of dynamic buckling in cylindrical shells, the problem uses dual variables in Symplectic space instead of variables in traditional Euclidean space. The symplectic eigenfunction expansion method gives out an exact solution space. So many problems are solved, which can not find the solution in traditional methods.

将哈密顿体系引入结构的动态屈曲研究中，其意义在于将结构的动态屈曲研究从传统的欧几里得几何空间进入到由原变量和对偶变量组成的辛几何空间之中，从而使辛本征函数展开的直接解析法得以实施，这样就可以求解许多以往半逆凑合法无法求解的问题，并且所得到的解空间是完备的。

其次，在对基于模糊聚类的识别方法研究中，根据各种热解参数在油气层预测中的影响程度，给出了构造模糊相似矩阵的几个有用的公式，以及改进的模糊聚类传递闭包法；根据每个样本点对分类的不同作用，提出了一种改进的模糊C均值算法；试验结果表明，这两种方法都可以有效地提高分类精度。

Identical data inequilibrium stats and similar shock-induced reacting flow fields are gained for tworeaction models when projectile velocity is 3km/s. In this case, the molar fraction ofdissociated methane is so small that the frozen flow or a very simple reaction modelcan well describe the flow field of weakly shocked methane. As projectile velocityincreases, molecular methane is readily dissociated and some stable products are formed. Only do the numerical results of the 40 reactions involving13 species approach to the corresponding experimental results.

计算表明，当飞片速度低(3km／s)时，两种反应模型给出冲击状态参数的结果基本一致，因为这时甲烷气体冲击波后的成分变化很小，说明可以用更简单的化学反应模型描述高温甲烷的化学反应过程；当飞片速度增大时，甲烷分子迅速的离解，反应产物容易形成稳定的化合物，只有13组元40反应模型的计算结果才能与实验结果接近。

By analyzing numerically the disks around a young stellar object and a black hole, we can obtain: the dissipation can not be neglected as a magnetic field is in small threshold value; in Keplerian disks, the magnetic field is smaller, the dissipation caused by anomalous viscosity and anomalous resistivity deviates from the ideal more greatly; the dissipative effects on magnetic instability become smaller as the radius r becomes larger.

通过分析年轻恒星周围和黑洞周围吸积盘的数值解可以得到：在磁场比较小的一段阈值内，这种耗散过程是不可忽略的；而且，磁场越小，由反常黏滞及反常阻抗引起的耗散过程对磁不稳定性的影响就越大；离中心体的距离r越大，耗散过程对磁不稳定性的影响越小。

On the days when dessert is a name given to a handful of chocolates and a little preserved ginger, when macedoine de fruits is the title bestowed on two prunes and a piece of rhubarb, then the orange, however sour, comes nobly to the rescue; and on those other days of plenty when cherries and strawberries and raspberries and gooseberries riot together upon the table, the orange, sweeter than ever, is still there to hold its own.

首先，橘子是日常生活中的常客，即便客观事实可能并非如此，但至少在水果店里，橘子确实是四季都有供应。）曾几何时，甜点仅仅就是一把巧克力加上一丁点腌制的姜，两个西梅脯加上一块大黄茎居然也美其名曰为水果什锦。那么相比之下，不管有多酸，橘子都可以说是解了燃眉之急，极大地丰富了人们的餐桌。又曾几何时，在那些衣食富足的年月，餐桌上樱桃，草莓，覆盆子和醋栗大聚会，好不热闹，但即便如此，橘子也依然能占有一席之地，而且此时的橘子吃起来无疑是最甜的。

This paper focuses on the stability study of Rhizopus oryzae IFO4697 when used for the methanolysis of renewable oils for biodiesel production. The results showed that water content was important for achieving high catalytic activity and good stability of the biocatalyst. The optimum water content was found to be 5%-15%. Both particle size and desiccation methods showed no obvious effect on the stability of the biocatalyst. With GA cross-linking pretreatment, the stability of the biocatalyst could be improved significantly. When Rhizopus oryzae IFO4697 repeatedly used for next batch reaction, direct vacuum filtration was found to be a good way for the maintenance of good stability of the biocatalyst.

The best theoretical solution to a partitional clustering problem is to find all possible partitions and choose the partition that minimizes the objective function. However, the enumeration of all possible partitions is impractical even for data sets of moderate size. Therefore, as an alternative, most partitional approaches use an iterative optimization technique. And this could be cause local minimum.

本文在分析了目前聚类的基本方法的基础上，指出以K平均法等为代表的分割聚类虽然理论上找到类的所有划分并使得目标函数最小就可以获得最优解，但由于对于相当尺度的数据集列举所有可能的划分并不现实，因而多数分割方法采用迭代优化技术作为变通。

The speed-sensorless vector control and the identification of motor parameters in this paper are the two novel research of vector control.Using asynchronous machine's mathematic model in three-phase static reference frame, this paper has derived it's mathematic model in two-phase static reference frameand in two-phase rotating reference frame, and got the coordinate transformance formulus based on the constant magnetic force and power force, by compared different field orientation methods, we can find that field orientation at rotor field can realize the decoupling of the stator current flux component

无速度传感器矢量控制和电机参数辨识是矢量控制的两个新的研究方向，本文利用异步电机在三相静止坐标系下的数学模型推导出两相静止坐标系、两相同步旋转坐标系下的数学模型，根据磁动势守恒和功率守恒的原则，得出各坐标变换公式；通过不同磁场定向方式的比较发现，异步电机按转子磁场定向时定子电流励磁分量和转矩分量可以比较方便地实现解耦。

Because I always believe that we must treat the current artists by the modern life experiences, therefore we can find obvious or unconspicuous relations about every element of the opuses with the modern life.
