Based on the established database for poplar and birch, the developed color measurement-matching system is used to carry out imitation of precious wood species such as Dalbergia fusca Pierre, Dalbergin bariensis Pierre and Juglans.

利用建立的杨木和桦木基础数据库，进行黑酸枝、红酸枝和黑胡桃等珍贵树材仿真，分别修正0~2次后即能达到要求，所模仿的珍贵木材材色与天然木材材色相近，着色均匀，色差小。

The results showed choosing the diameter as 1.0~2.0cm thick root segment, the length is above 15cm, using 108 Sheng Gen Fen or Du Gen Su to declinate cuttage, the survival rate can reach to 70%,And they can become independent plant.

结果表明：选择直径为1.0~2.0cm粗的根段，长度为15cm以上，使用108生根粉或杜根素药剂处理后，进行斜向扦插，成活率能达到70%以上，并成为独立的植株。

As the density of Al and Cu was quite difference,it was apt to delaminate and restrain the process of alloy by wet milling.The case was improved when dry milling,though it would be some reunite with the time of ball-milling prolonging.(2)The best technique parameters of high energy ball milling to prepare metastable powders of Cu-Al alloy were;the addition of Al powders was 1% in quality,the powders of Cu-Al were completely alloyed after high energy ball milling for 20 h.

1提出采用高能球磨制备Cu-Al合金粉的有效方法，认为由于Cu和Al的密度相差比较大，采用以液态酒精为过程控制剂的湿磨时，容易发生分层，抑制了合金化，采用干磨时，以硬脂酸为过程控制剂，虽然随球磨时间的延长会发生轻微的团聚，但能达到良好的合金化效果。

Plant Virology 2 S T. H. Chen, FThe course will give conventional and molecular level of plant viruses in order to help the students to get much theoretical and practical knowledge about plant virology. The contents cover the molecular structure of virion and genome, virus isolation, dentification and purification, transmission, variation,ecology, nomenclature and classification, diagnosis and control.

本课程除传统植物病毒学范畴外，并涵盖从分子层次讨论植物病毒之构造，引起之植物病害，田间发生及防治，期能达到理论与实务并重；内容包括植物病毒分子层次的构造及核酸组成，病毒分离、鉴定与纯化，在寄主体内之增殖及转移，媒介传播、遗传及变异，其引起之病害及田间发生生态与防治。

Experimental results show that this method can localize multiple dipolar sources easily. The speed of MEG source localization can be improved greatly and the accuracy of source localization is satisfactory.

实验结果表明，此方法可实现多个脑磁图源的定位，并且速度大大加快，同时又能达到所要求的定位精度。

Many methods are used to solve nonlinear problems, their rate of convergence is quick, for example, Newton-moser method, King-werner method, they are attentioned widely because of the quick rate of convergence. While these methods are used to solve singular problems, the rate of convergence is slow, it is discommodious for us to solve practical problems.

有许多方法在求解非奇异问题时，它们的收敛率是很快的，有些甚至能达到二次收敛，例如Newton-Moser法、King-werner法，这是所熟知的，因其收敛速度快，并且简单易用而广受重(来源：AB17C论文dddd网www.abclunwen.com)视。

因此，依据当地的自然条件和资源条件最大限度地重新开发利用塌陷地，使采煤塌陷地在生态修复以后能达到最佳的生态、社会和经济效益，满足矿区可持续发展的需要，是目前迫在眉睫、亟待解决的问题。

A large drop in hardness appears in as deformed samples at a temperature 45 ℃ lower than the start temperature of the exothermal peak after isochronal annealing, indicating that the recrystallization and grain growth process is closely relatine to annealing time and temperatur.

出现明显晶粒长大的温度较DSC曲线显示的放热峰起始温度低45℃左右，这主要是由于变形组织的回复再结晶过程是退火温度与时间的函数，降低处理温度并延长处理时间能达到与高温短时处理相同的效果。

Because the UHE γ-rays are strongly attenuated by the extragalactic background radiation field of the infrared and 2.7K microwave photons.

因为1～100TeV的初级宇宙γ光子在穿过宇宙学距离时，将遭到宇宙红外背景光子和微波背景光子的强烈吸收而不能达到地球大气顶部。

Though Therese was not like her foundress, St. Teresa of Jesus, has left no explicit treatise on prayer, Camelite writer think that : Prayer is the main element of Therese's spirituality, her "Little Way" is a path leading to God, which can be united with God.

虽然小德兰并没有如她的会祖圣耶稣德兰，写下很多有关祈祷的著作；不过圣衣会的神修作家都认为：祈祷是小德兰神修的主要素材；她的神修方法──「爱的小路」，就是一条朝向天主的捷径，能达到与主结合。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
