D. Declaration of nonprimitive types such as String, Vector ans so on allocates memory space for the object.
但是严格来讲此题的答案有待确定,因为只有原始类型的实例变量和类变量的声明在类对象被创建/类被加载时完成内存的自动分配,而原始类型的局部变量必须显式初始化,从这点来看原始类型的局部变量没有被自动分配内存,SL275中只提出了非原始数据类型的变量必须使用new Xxxx完成内存的分配而没有指出原始数据类型的变量是否在声明时即自动进行内存分配,而从局部变量不能在显式初始化前使用这点来看在声明时没有进行内存分配。

A computer-aided local transient flow property measuring system was developed using a high speed CCD camera coupled with optical fibers in order to study the Gas-liquid-solid three-phase jet loop reactors. SnO2 crystal films were orientally deposited on the alkoxysilane molecule-coated hydroxyl glass substrates so as to prepare surface-marked particles as the tracers. An image analysis system was established to identify different phases. Stroboscopic photography was utilized to extend the measure range. The developed measuring and analysis system was capable of determining accurately the local transient flow property in a G-L-S jet loop reactor. Based on the above system, local transient flow properties of gas, liquid, and solid phase were measured and studied the influences of fluid property, operation and configuration parameters on the reactor.

After some generations the population diversity would be greatly reduced and the algorithm might lead to a premature convergence to a local optimum. To circumvent these shortcomings, the chaotic dynamic system is introduced in the studies of chemometric algorithms. The chaotic mapping itself is very sensitive to the initial state in a manner similar to the statistical randomness but with its underlying patterns appearing to be phantasmagoric in a deterministic style.
神经网络是一个优异的非线性建模工具,但其突出的缺点就是潜在的预收敛到局部最优点或过拟合导致的错误预报模式;遗传算法用于优化过程其目的是为了避免陷入局部最优点,但事实上由于在传统遗传算法的进化过程中只有少数最好的成员被保留下来用于产生子代成员,经过一定代数的进化后群体成员的多样性就会显著下降,也很可能过早收敛到局部最优点。

Neural networks based on local sequence and amino acid component with the best structures and linear equation are constructed. The results of testing to the networks indicate that the forming of cis-proline has distinct relationships with local sequence and amino acid component. A new method for peptidyl prolyl cis/trans conformation prediction based on the theory of support vector machines was introduced. The SVM represents a new approach to supervised pattern classification and has been successfully applied to a wide range of pattern recognition problems.
