Because of their intrinsic characteristics of hard computability, they cannot be solved accurately by efficient algorithms up to now. Since these problems have many applications in real situations, it is quite important to find some applicable algorithms.

由于难计算是这类问题的固有性质，因此它们目前尚无法用有效算法精确求解，但这些问题在现实领域中有着许多广泛的应用，因而寻找其实际而有效的算法就显得颇为重要了。

If singular value curve is convex in the coordinates 'k' of maximum peak of curvature spectrum, then the number of effective singular values is k; if singular value curve is concave in the coordinates 'k', then the number of effective singular values is k-1, and this rule is tested by the signal processing examples.

如果奇异值曲线在曲率谱最大峰值的位置坐标k处是凸出的，则有效奇异值的个数为k；如果奇异值曲线在k处是凹进的，则有效奇异值的个数为k-1，通过信号处理实例证实了这种结论。

This makes the Group hard to operate concertedly. Accordingly, how to set up a control mode which applies to the subsidiaries and establish an effective management framework to realize the resource collocated availably has become an urgent task.

Are highly dependent on applications satellites. With the development of times and technology, the strategic instruments of the US global hegemonism transform are changing from export control, trade embargo, finance sanction, full-scale sanction, no-fly zone for aircrafts to NSLZ, and even the military strike from the outer space. By using them concertedly, the US can prevent and control the effective flow of material, personnel, currency, labor and information in or out of other nation in the four dimensions of land, sea, sky and electromagnetism.

随着时代和技术发展，美国全球霸权主义战略工具逐渐从出口管制、贸易禁运、金融制裁、全面制裁、飞机禁飞区、发展到"卫星禁发区"直至自外空进行军事打击，多种手段相配合就能够有效阻止和控制别国陆、海、空、天、电磁四维空间中的物资、人员、货币、劳务、信息的国际、国内有效流动。

Study on how to ensure reasonable guarantee level based on share risk principle makes good sense for optimization of resources, protection of customers' benefits, incentive firms to rational investment, improvement of production and operation efficiency of concessionaire.

基础设施特许经营是实现政府与企业合理分工与合作的一种有效方式，可以有效解决当前我国基础设施发展中的政府财政资金不足与生产经营效率不高等问题。

This paper uses mixture density networks to forecast the time-varying conditional density values of financial time series, and puts forth a new numerical algorithm to calculate Expected Shortfall. The application in Hong Kong Hangseng index approves that Value-at-Risk at high probability levels is accurate, and that it also has good forecasting ability in fluctuation. MDNs can effectively describe the empirical distribution of returns and the volatility mechanism, and is a new model for measuring financial market risk.

基于混合密度网络模型估计金融时间序列的时变条件密度，提出采用数值模拟方法计算Expected Shortfall的新途径，对香港恒生指数的实证研究表明，VaR的预测精度在高端分位点较好，模型评估指标反映出预测效果良好，混合密度网络可以有效地描述收益的经验分布统计特征和波动规律，是一种有效的金融市场风险测量模型。

The calculation of the relative curvature and the distance of corresponding points of effective area of gear flanks to the face cone of the honing wheel proves that the effective area locates totally within the boundary of engagement.

通过对诱导法曲率和珩磨轮上与齿面有效工作区对应点到珩磨轮面锥的距离的计算，保证了齿面上的有效工作区域全部落在啮合界限以内。
