The main idea of this optimization is to strip the vtable initialization code from abstract class for abstract class the vtable is empty, while it is initialized in contructor

这一优化的主要思想是，以剥夺从抽象类的虚函数表的初始化代码（抽象类中的虚函数表是空的，而它在构造器初始化

Accounting on the cash basis does not really reflect the revenue and expenditure as well as the creditor rights and debt; fixed asset without depreciation increases the asset spuriously; the unreasonable write-off of invisible assets; the acceptance of non-cash assets donation increases the expenditure spuriously; the basic construction uniline account calculation can not reflect the finance, revenue and expenditure comprehensively, completely and correctly.

现行高等学校会计制度存在以下不足：收付实现制的会计核算基础不能真实反映高校的收入支出以及债权债务状况；固定资产不提折旧虚增了高校的资产；无形资产的摊销欠合理；接受非现金资产捐赠业务的会计处理虚增支出；基本建设单列账套核算不能全面、完整、准确地反映高校的财务状况和收入支出情况。

Results Being compared with the normal group, the PDS mice showed a slower growth of body weight and a lower body temperature, a shorter mean retention time of chyme in digestive tract and faster gastric emptying velocity, a lower gastrin content, and a higher motilin content. Also splenic and thymus indexes were found to follow a downtrend in the PDS mice. Three dosages of SJZD showed a restoration effect on the above all indexes, and the high dosage was the most effective one, especially.

结果脾虚证小鼠体重增长缓慢，体温降低、消化道内食糜平均滞留时间缩短、胃排空加快、胃泌素的量降低、胃动素的量升高，脾脏和胸腺指数降低。3种剂量的四君子汤对脾虚证小鼠以上各指标的变化均有明显的矫正作用，以高剂量效果最佳。

Void Rays are also great to do an attack on their base while you have a diversionary force distracting them in another place.

当你有单位在另一个地方牵制住对手的时候，你的虚光舰同时也可以对他们的基地进行攻击。2～3艘虚光舰可以比同等资源下的飞龙更快的摧毁母巢。

The thesis analyzed chiefly on on law of physical sign disposition of deficiency of spleen-QI in pedo-eczema.Using pykno-analysis, data has been analyzed. We got 23 physical signs of statistical significance,and had non-conditional logistic regression analysis to them. We got 11 physical signs of great value in pedo-eczema diagnosis,including dim-coloured anthema, athrepsy body, weak pulse, diarrhea , etiolate complexion,light texture of tongue,soft skin, house-wife hand,dim qichi, fissured tongue, bluish tendon in shangen etal.And contrast with former diagnostic criteria of deficiency of spleen-QI published by TCM administration bureau, unearch part of the unnoticed physical signs.

论文着重分析了小儿湿疹脾气虚证的体征分布规律，采用频数分析方法，对数据进行统计学分析，分析出其中具有统计学意义的23项体征，并对其进行非条件性logistic回归分析，得出对小儿湿疹诊断具有重要价值的疹色暗淡，形体消瘦，脉无力，便溏，面色萎黄，舌质淡，尺肤松软，手掌纹理增多，气池暗，裂纹舌，山根青筋等11项体征，并与以往国家局的脾气虚证证候诊断标准对照，从而发掘出部分以往未被重视的体征。

A new technique is presented in this paper for frequency estimation of single real sinusoid at a low computational cost using the real parts or imaginary parts of Fourier coefficient s.

提出了一种利用信号离散傅里叶变换系数的实部或虚部来构造频率修正项的新算法，算法只需傅里叶系数的实部或者虚部的最大值附近的3个DFT系数来构造频率修正项，避免了复数运算从而有效减少了运算量，同时算法的频率估计精度接近CRLB(Cramer-Raolow bound)。

将选择施加在&虚结构&控制点上的虚载荷作为形状优化的设计变量，并将它与无网格Galerkin法相结合来开展结构形状优化研究，采用罚函数法来施加边界条件，通过直接微分法建立了结构形状优化的离散型灵敏度分析算法，利用无网格法研究了节点坐标关于设计变量导数的计算。

A simple model was developed to investigate the generation mechanism of virtual cathode oscillation microwave based on space-charge effect under small signal condition.

采用小信号理论，在考虑到透射、反射束电子不同作用下，分析了虚阴极振荡器产生微波的机制，获得了计算微波主频的方法，讨论了增强束波作用效率的方法，并提出一种新型结构的虚阴极振荡器。

The optical potential of a nucleon in the nuclear medium is identified with the nucleon self-energy.

核子的光学势等价于核子在核介质中的自能，论文中RMOP的实部用G=V+AG在DBHF方法下计算得到，虚部则采用二级G矩阵极化图的虚部。

Attempts to correlate this metric output with both experimental target detection probability and detection time yield rather good results.(2)Based on the Search_2 dataset provided by TNO Human Factors Research Institute of Netherlands, via a simple mathematical model, the target structure similarity measure is used to quantitatively describe the effect of background clutter on the human false target detection probability.

2以目标结构相似性尺度为背景杂波度量因子，以荷兰TNO人类因素研究所提供的Search_2试验数据库为基础，通过构建数学模型的方法，定量分析了背景杂波对观察者目标虚警概率的影响，并在此基础上，讨论了人眼视觉在背景杂波干扰下的虚警概率表征模型。
