I give everybody to introduce some behind-the-scenes plotting, the strawberry use also to calculate few, fruits and so on apple, peach, grape, banana, so long as shifts to an earlier time going on the market, and has the appearance, many are depending on the ripener accelerate ripening, I chats with a relational good commerce when she tells me to say her to stock with goods when only looked that the strawberry and the freshness, is a price again, but also which kind has, does not have the environmental damage she not to ask, the customer mostly also only cares about this difference, even if because the present price has fallen half, also the very few some people buy oneself to eat, majority of has bought the attireGives a present to the gift box.

我给大家介绍一些黑幕，关于草莓，我跟一位关系不错的商贩聊天时她就告诉我说她进货时只看草莓的个头和新鲜度，再就是价钱，还有在哪种的、是不是无公害她都不问，顾客大多也都只关心这两样，因为即使现在价格降了一半，也很少有人买回家自己吃，大部分都是买了装到礼盒中送礼。草莓用催熟剂还算少的，苹果、桃子、葡萄、香蕉等水果，只要是提早上市且有卖相的，多是靠催熟剂催熟的，且催熟剂用的量更大，我提醒大家注意，换季水果少买。

We draw the following conclusions:(1) among three artificial woodlands, Robinia pseudoacacia had the most microbial biomass and activity;(2) there were no significant effects of the different artificial woodlands on soil microbial diversity.

总之，3种人工林相比较，种植刺槐林与其它两种人工林相比更有利于提高微生物的量及代谢活性，微生物的功能多样性受不同树种的影响较小。

Histological and cellular research on rachis of healthy and inoculated spikes of the mutants at the different stages showed that, structure and developed tendency of cortical sclerenchyma tissue and green tissue and fibrovascular tissue in the rachis were alike between the mutants and their donors at anthesis stage, which also showed no apparent difference in the inoculated spikes'rachis between the mutants and their donors, major difference was that the mutants had less hyphae number than their donors.

对抗赤霉突变体的健康穗及接种穗的穗轴细胞组织学研究结果显示，抗性突变体与其感病亲本的花期健康穗轴在皮层厚壁组织、绿色组织及维管组织结构上基本一致，不同发育时间的变化趋势也一致；接种处理后，抗性突变体与其感病亲本的穗轴组织在各方面的变化趋势相一致，变化量也无明显差异。

The SDC and DTA were used to determine the phase transformation temperature of gray cast iron with various nitrogen content.

After comparing the model result with the record of prehistoric earthquakes along the Shanchiao fault and the depth of Tertiary basement, we suppose that the seismism of Shanchiao fault should have left-lateral slip portion and it was more active in the north fault section in the Taipei basin.

另外，我们将模拟的结果与古地震的错位记录和台北盆地第三纪沉积岩的基盘深度分布相比较，结果显示过去以来山脚断层的活动在台北盆地西北侧或更北方的断层面上有较大的滑移量，且具有左向滑移的分量。

The parameters of X-ray sensitometry ,such as sensitivity,gradation,gamma,fog,and resolving power,granularity,silver contents of emulsion layers of films and total thickness of coating layers of films produced in Russia and by foreign companies and the quality classification of these films by using recommended Russian standard of quality classifi.

介绍了无损伤检测用射线技术胶片的质量分类国际标准和俄国标准的要点，做了俄国国产和国外射线技术胶片的 X射线感光测定和解相力、颗粒度、含银量以及乳剂层厚度的检测，将这些胶片按推荐用于俄国的分类标准做了分类。

The relationship of ore-forming fluid salinity-aqueous cation lg demonstrated that water-rock reaction was also one of the potential gold deposition mechanisms besides mixing with meteoric water. All of these were consistent with that sericitization and pyritization hydrothermal alteration were extensively/intensively distributed (as high as 33%), gold grade linearly correlated with degree of alteration,∑REE depletion and δ〓O enrichment

成矿流体盐度-液相主要阳离子组分1g演化规律研究表明，除与大气降水的混合-稀释外，水-岩相互作用也可能是造成金沉淀的重要因素，这与本文所研究金矿床中绢云母化、黄铁矿化等热液蚀变广泛发育(可高达33％)，Au品位与热液蚀变程度、REE亏损量及δ〓O富集规模表现出较为明显的线性关系等一系列地质事实相吻合

In this paper, the law of change of nitrogen content in the metal of welding seam under different forms of shielded flow is studied by means of Laser shadowgraph flow field showing equipment and the gas pulse-chromatography.

本文采用激光阴影法流场显示装置和脉冲—色谱气相分析仪，研究了不同气流形态下焊缝金属中含氮量的变化规律。
