查询词典 after a time

In this scheme, the description of unitary evolution and quantum measurement is unified and the quantum control operation is represented by probability state transition. The algorithm works as follows. At first a measurement is applied on the system. If the state after collapse is not the desired eigenstate, then system evolution will go on. After a period of time, the system is measured again. The process will go on like this until we get the desired eigenstate by measurement. Finally the system is driven to the target state with admissible control as before.

4把本征态能控性概念进一步向前发展，提出了概率能控性的概念，将幺正演化和量子测量这两种量子控制手段统一的用概率状态转移来描述，并针对一类特殊的本征态能控的系统，提出了幺正演化和测量交替进行的量子反馈控制策略：如果单步测量所得到的本征态不是期望的本征态，则让系统以这一本征态作为新的初态进行下一步的幺正演化，然后在适当的时候再次测量，让系统塌缩到某一本征态，如此重复进行，直到达到期望的目标态为止。

After a little: after a short period of time.

However, after that time, six patients died, four of whom had taken infliximab. The causes of death in those taking the drug included histoplasmosis 4 weeks after the final infusion; Listeria encephalitis 3 years afterward; prostate cancer 3.5 years afterward; and natural causes 10 months later. The two who received placebo died from a suicide and a cerebrovascular accident.

但在这之后，6例患者死亡：其中英夫利昔单抗组4例——1例患者在末次输注4周后死于组织胞浆菌病、1例患者3年后死于李斯特菌脑炎、1例患者3.5年后死于前列腺癌，1例患者10个月后自然死亡；安慰剂组2例患者分别死于自杀和脑血管意外。

After a long time lonely life,i met a good guy maybe it's a largess god gave me,at the same time i found here came the happiness again.

This paper took the paddy soil after saving-water irrigation as the object,which is from Taian town of Yangzhou city, selected microtomy to get undisturbed soil samples respectly between two periods(before irrigation and after harvest), built up the analytical technique of numerical picture system.It also set up the analysis index of macropore structure,such as the number of macropores N, the macroporosityφ,the area A, the perimeter P and so on. Meanwhile make analysis contrast about horizonal distribution among 4cm, 6cm and 8cm scanning areas, vertical differences per 2cm unit and contrast in time between different periods.

本文选取扬州市泰安镇节水灌溉后稻田土壤为研究对象，采用切片法取开灌前和收割后的原状土样，运用数字图像制备技术，获取大孔隙数目N、大孔隙度Φ、面积A、周长P等分析指标，对4cm、6cm和8cm扫描直径内大孔隙作水平向差异性分析，对2cm单位深度上作垂向差异性分析以及对两个不同时期作时间差异性分析。

The princess, who had never liked Pierre, and had cherished a particularly hostile feeling towards him, since after the old count's death she had felt herself under obligation to him, had come to Orel with the intention of proving to him that in spite of his ingratitude she felt it her duty to nurse him, but after a short time she felt, to her own surprise and annoyance, that she was growing fond of him.
