Properties of efficient portfolios and the efficient frontier to the model are systematically analyzed. Our main results concerning the properties are: every efficient portfolio can be solved by minimizing portfolio risk under a given level of portfolio return or by maximizing portfolio return under a given level of portfolio risk; on the efficient frontier, the risk is a convex and strictly increasing function of the return and the return is a concave and strictly increasing function of the risk; the utility function on the efficient frontier can be expressed as a quasi-concave function of the risk or the return if the investor's utility function is quasi-concave.

从理论上系统地对该模型下的有效投资组合和有效前沿的性质进行了分析，结果表明：每一个有效投资组合可通过在给定期望收益水平的条件下最小化投资组合风险来获得，或者在给定风险水平的条件下最大化期望投资组合收益来获得；在有效前沿上，风险是收益的严格单调递增凸函数，收益是风险的严格单调递增凹函数；当投资者的效用函数是拟凹函数时，则有效前沿上的效用可表达成风险或收益的拟凹函数。

Secondly, a joint pricing and capacity allocation model is formulated considering bulk demand. Chance constrained programming is used to transform the stochastic model. Numerical examples show our model and method is more near the simulation results than the deterministic programming and bigger learning coefficient leads to higher profit contribution.

接着，建立了考虑批量需求的BTO模式下制造企业定价与能力分配的集成模型，利用机会约束规划方法对此随机模型进行转化和求解，算例仿真表明机会约束规划方法较确定性规划方法更好地反映了随机连续需求的分布和波动特征，其期望利润贡献与仿真结果更接近；学习效率越大，最优价格越低，接受订单数量越多，期望利润贡献越高。

Two kinds of DPA estimators are given by way of Nonstandard Analysis andprobability parameter sampling,respectively.One kind of DPA algorithm,based on a sample pathof GI/GI/l system,can estimate simultaneously EST and expected busy period length gradient.

分别从非标准分析和概率参数抽样方式的角度建立了两类DPA估计量，特别地，前一类DPA估计量可以同时估计顾客的期望系统时间和忙期期望长度的梯度。

The impacts on the diameter levels V and VI were indicated as abnormal increase of survivorship, negative values of mortality and decrease of mean life expectance whereas the impacts on the diameter levels III and IV were opposite to the levels V and VI. The survivorship curve of the Quercus variabilis population was fit with Deevey II.

静态生命表分析较好地反映出栓皮栎种群生长历史中的消长过程，清楚地透视出20年前坑木择伐对种群动态的长期影响，即径级V和VI（直径8~12 cm）存活株数异常增加、存活率提高、死亡数和死亡率出现负值以及平均期望寿命降低；而相应地对径级III 和IV带来与径级V 和VI相反的作用。

One, study character is in us in education, discover not hard, the student's study, dependence is very strong, always be used to a teacher all-around specific arrangement, once give them time, a lot of students appear not know what to do, faineant even; is studying a method, be used to machinery repeating, face the study rhythm during study and capacity, times feeling gets tired of the study mood; that dealt with; him student to affect them with the expectation fixed position of parent impropriety many students and parent often the study result with the static state, regard only hope as orientaton, not to be pooh-poohed makes dynamic analysis at whole to learning process, undertake ego is adjusted scientificly....

一、学习品质在我们在教学中，不难发现，学生的学习，依靠性很强，总习惯于教师全方位具体布置，一旦把时间交给他们，很多学生就显得无所适从，甚至无所事事；在学习方法上，习惯于机械重复，面对学习期间的学习节奏和容量，倍感疲于应付；学生本人和家长不适当的期望定位影响了他们的学习情绪；不少学生和家长往往以静态的学习成绩，作为唯一的期望取向，不善于对学习全过程作出动态分析，科学地进行自我调适……。

When it was all over in October 1946, and ten defendants had been hanged messily in the Palace of Justice's gymnasium, this first Nuremberg trial stood as the judicial Everest of those who hoped, as Jackson did, that the rule of law could punish, if not prevent, the atrocities of war.

当1946年10月一切结束、10位被告在&正义宫&健身房被不体面地绞死时，纽伦堡这次首开先河的审判耸立为人们所期望的正义之巅（直译是正义之珠穆朗玛峰）。亦如杰克森所期望的：对于战争暴行，即使法律不能防止，也应能惩罚。

The big stores have a professional Santa Claus, white-bearded, red-mantled, black-booted, perspiringly presiding over a "Magic Cave" or a "Toyland", and solemnly noting the Christmas Eve requirements of hundreds of exited children.

每家大商场都安排有专职的圣诞老人。他们蓄着白胡须，身披红斗篷，脚踏黑靴，汗流浃背地主管着&魔洞&或&玩具天地&，并郑重地记下许多兴奋不已地孩子们在圣诞夜期望得到的东西。

Such a choice provides the convenience to analyze the working and repair processes in power system operation, and the possibility to estimate failure frequency and unsupplied energy in the system.

在模拟方法上，本文首次应用条件数学期望和条件分布的概念和方法，提出了以状态持续时间的期望代替其模拟采样值的想想，显著地降低了可靠性指标统计量的方差。

You may continue to exceed onlookers' expectations but shall always fall short of the boss' expectations.

你可能不断地让超越别人的期望，但是却总是达不到老板的期望。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.
