结果表明：随着淀粉乳浓度的增加，FBRM测得的淀粉颗粒粒径呈现先增加后减小的趋势，当浓度达到10%时，粒径大小趋于稳定；在高浓度淀粉乳中，搅拌速率对淀粉颗粒粒径的影响较为显著，在低浓度淀粉乳中，则没有显著的影响；采用浓度小于50%的乙醇和异丙醇以及高于75%甘油作为介质时，可以得到较为稳定的粒度分布；不同种类淀粉颗粒的粒径分布曲线趋势不同。

Firstly, based on the stability criterion for the nominal discrete singular time-delay system, a sufficient condition for the existence of the static output feedback controller in terms of linear matrix inequality with linear matrix equality constraint is established, which ensures that the resulting closed-loop system is regular, causal and robustly asymptotically stable, and the static output feedback controller is designed by the feasible solution of the linear matrix inequality with linear matrix equality constraint.

首先基于标称离散广义时滞系统的稳定条件，以受限线性矩阵不等式形式，得到闭环离散广义时滞系统正则、因果且渐近稳定的充分条件，同时利用受限矩阵不等式的可行解给出静态输出反馈控制器的设计方法；然后采用矩阵的正交补，把求受限线性矩阵不等式的可行解问题转化为求严格线性矩阵不等式的可行解；最后的数值实例说明了所给方法的有效性和正确性。

在此基础上进一步从这几类影响因素出发，分析了国际短期资本对我国经济金融系统的影响，并得出了短期资本的流入会打破原有经济的稳定，在国家为了恢复经济稳定的过程中，国际和国内目标实现发生了矛盾，而这一矛盾的根源就在于我国经济的外向依赖性的结论。

The replacement of toxic and volatile organic solvents as reaction media or an efficient catalyst with environmentally acceptable alternatives are an area of tremendous importance in modern organic synthesis. Basing the review about solid-phase synthesis with simple separation, the liquid phase organic synthesis supported by the solution polyethylene glycol and the chemical reactions in the medium of PEG, herein we are going to study the synthesis of 1-amidoalkyl-2 -naphthols in presence of the solution catalyst or the solid catalyst and the synthesis of thiourea in PEG-400 medium.

对工程区右岸地下引水洞室群的围岩稳定性进行系统研究，可以控制工程投资，提高施工质量和支护设计精度；分析评价洞室围岩的整体及局部稳定性，消除洞室稳定的潜在危害，对保证地下洞室的施工安全、围岩的长期稳定以及优化设计具有十分重大的工程实践意义。

Treatments were as follows: fertilization during leaf-expansion period, fertilization during green-leaf period, and no fertilizer. Results showed that individual leaf area, thousand-leaf weight, and leaf distribution were relatively stable with little influence from fertilization. Fertilization during leaf-expansion compared to the green leaf period significantly increased leaf number, leaf weight per plant, and leaf area index. Fertilization during led-expansion also significantly increased the total weight of leaves corresponding to each branch. The 14th to the 17th branches had the largest number of leaves in the canopy with fertilization increasing the weight of each branch but not changing the center of the canopy.

结果表明：毛竹单叶面积、千叶质量和叶片分布受施肥的影响较小，是较为稳定的指标；展叶期施肥处理（处理1）能显著增加单株立竹的叶片数量，到7月底，其单株立竹叶片总质量和叶面积指数分别比绿叶期施肥（处理2）提高14.8%和13.7%，比不施肥提高27.6%和24.5%；冠层14~17档是单枝叶片数量最多的区域，施肥能增加各枝盘叶片的质量，但对林冠重心的分布无影响；单叶叶面积稳定后（6月），处理1的叶绿素测定值和光合速率显著高于处理2和对照，而处理2与对照间无显著差异。

Suetonius wrote, concerning the long months following Nero's death, that the empire "for a longtime had been unsettled, and as it were, drifting, through the usurpation and violent death of the three emperors, was at last taken in hand and given stability by the Flavian family."
