This paper discussed almost everywhere upper semiconvergence of optimal solution set of empirical approximations for stochastic programs.

本文对随机规划经验逼近最优解集的几乎处处上半收敛性进行了研究。

Firstly, an empirical approximation model of stochastic programming is obtained by replacing the probability measure of original program with empirical probability measure. Sequentially, the constrained stochastic programming is transformed into an equivalent unconstrained stochastic programming. Finally, using the epi-convergence theory, the almost everywhere upper semiconvergence of optimal solution set of empirical approximations for stochastic programming is obtained.

首先通过经验概率测度替代初始规划的概率测度得到随机规划的经验逼近模型，然后将带有约束的随机规划问题转化成与其等价的无约束的随机规划问题，最后利用上图收敛性理论，给出了随机规划经验逼近最优解集的几乎处处上半收敛性。

The reconstruction problem is ill-posed, so two optimal criterions, the least module and the smoothness criterion base on Tikhonov regularization technique, are introduced into reconstruction algorithm. Many regularization parameters choice strategies are investigated, and the TPA(Two—Parameter Algorithm) strategy which is based on the Morozov discrepancy principles, is implemented in two regularization reconstruction algorithms.Numerical experiment results show that the nonnegative and smoothness constraint condition can overcome the difficulty of iteration semiconvergent, preconditioned technique can improve convergence rate and reconstruction accuracy, smoothness regularization criterion can meliorate ill-posed problem of reconstruction and enhance iteration stability, and the TPA is an effective strategy of regularization parameters choice.

数值试验表明：在共轭梯度法中引入非负约束和光滑约束改善了迭代的&半收敛&性，非负约束保证了解的非负性，光滑约束抑制了重建解的振荡现象，约束算法的重建精度与无约束算法相比大幅度提高；在约束共轭梯度重建算法中引入预优技术，可以加快算法的收敛速度，提高迭代的稳定性和重建精度；引入光滑准则的正则化技术可以有效改善图像重建问题的不适定性，加快迭代的收敛速度，提高迭代的稳定性和图像重建质量，计算正则参数的TPA算法在闪光照相图像重建中是有效的。

Than between the rN-ELISA and IDEXX ELISA kit (90.8%), therefore the rNM-ELISA was selected as a optimal method to prepare kit for determine antibodies to PRRSV. The storage life of the rNM-ELISA kit at 4℃ and -20℃ was 12 months at least by adding protein stabilizer to reagents in the kit, this provided pig industry for our country with a serodiagnostic method which had advantages of high sensibility、strong specificity、long period of validity、safety and no shedding PRRSV.

将建立的rN-ELISA和rNM-ELISA分别与IDEXX ELISA试剂盒进行比较检测327份猪血清，结果rN-ELISA和rNM-ELISA的特异性差异不大，rNM-ELISA与IDEXX ELISA试剂盒的阳性符合率相对较高（92.3％），选择rNM-ELISA作为制备PRRSV抗体检测试剂盒的方法。

The experimental results indicated that the addition of yellow serofluid had better nitrogen source effects than carbamide with its optimal addition level as 2 %(cell concentration increased by 18 %, bud ratio increased by 16 %, and liquor yield by alcohol fermentation increased by 2.2 %), which could settle the problem of environment pollution induced by direct discharge. The use of yellow serofluid in the production of alcohol from cassava could increase alcohol content in fermenting solution and liquor yield by 14.2 %Vol and by 35.5 % respectively.

结果表明，添加黄浆水作为酒母培养的氮源效果优于尿素；最适添加量为2 %；成熟酒母发酵液中细胞浓度比尿素作营养盐时提高18 %，出芽率提高16 %，酒精发酵出酒率提高2.2 %；可解决直接排放带来的环境污染问题；用于木薯原料酒精发酵，发酵液中酒精度可达14.2 %Vol，原料出酒率为35.5 %。

We don't want to biopsy more than once," he said, adding that this strategy is viable because "the kids we follow are in the medical system, so we can afford to be patient and try to determine the optimal time for biopsy with serial serologic tests.

我们不希望活检次数超过一次，&他补充说，这一策略是可行的，&我们随访的患者均在全美医疗系统中，因此，我们可通过耐心地进行多次血清学检查以试图确定活检的最佳时间。

The acidity of HZSM-5 was due to the non-framework aluminum species, i.e., SiAl. The intensity of acid sites of HZSM-5 declined while the quantity of acid sites increased with dehydration temperature, with optimal intensity and quantity of acid sites and maximum toluene conversion of 28.2% at dehydration temperature of 400℃.

HZSM-5分子筛的酸性变化主要是由于非骨架铝物种SiAl的变化而引起，随着脱水温度的升高，HZSM-5分子筛酸中心的强度下降，但酸中心数量增加，当脱水温度为400℃时，HZSM-5分子筛的酸中心强度和数量达到最佳，甲苯转化率为28.2%。
