The pleunm anti-static insulated material housing prevents short circuit led by the contact of welding spot and the metal channel of word sign. At the same time, the circuit uses particular constant current design and lightning arrester. Silicon rubber leads between modules of anti-aging and anti-cracking guarantee the long-term work in bad environment of open area while the low resistance of lead reduces the affection to the emitting brightness of LED by voltage drop.

其外壳采用阻燃防静电绝缘材料，可防止 PCB焊点与金属字槽壳的接触而产生短路，同时电路采用独特恒流电路设计及雷电吸收装置，模组间连接线采用软硅橡胶导线，在恶劣的户外恶劣环境下长时间使用，导线不会老化脆裂，同时导线内阻比较小，降低压降对LED发光亮度的影响。

After treatment of 50℃ for 1 minute, Fvi decreased to 70% and further reduced to about half of its control during following readaptation to room temperature in 60 minutes.

小麦叶片经50℃1分钟高温胁迫后，其Fvi降至对照的70％，在随后室温下60分钟内又降至50％。

The method includes the following steps: firstly, a spherical neighborhood of present sample points is established by using the geometric spherical-modelling theory and all the sample points contained in the spherical neighborhood are adopted as candidate neighbor points, thus not only preserving the effectivity of the dimension reduction capability when data sets are sparse but also getting the advantages of low-sensitivity to isolated points and good stability of the preserved topological structure; then a data relevance matrix more matching semantics can be obtained by relevance measurement based on route clusters to update the candidate neighbor points in the spherical neighborhood and optimize the regular neighborhood space of the present sample points, thus improving the phenomenon that the dimension reduction of sample sets provided with folded curved faces is apt to suffer the integrated-structure distortion in case of heterogeneous data distribution.

首先利用几何开球原理建立当前样本点的球状邻域，将包含在球状邻域内的所有样本点作为候选近邻点，不但能够保持在数据集稀疏情况下的降维性能的有效性，而且具有对孤立点敏感性不高、保留拓扑结构稳定性好的优点。然后利用基于路径聚类的相关性度量得到更符合语义的数据相关性矩阵，用来对球状邻域内的候选近邻点进行更新，优化当前样本点的规则邻域空间，改善了当数据不均匀分布时在带有折叠弯曲面的样本集上降维容易出现整体结构扭曲的现象。

On the basis of analyzing characteristic of Daqing crude oil and according to mechanism of PPD, the graft copolymer of EVA and octadecyl maleimide was synthesized.

本文结合大庆原油的物性特征，在降凝机理的指导下，以EVA的烷基马来酰亚胺接枝反应，合成了一类新型原油降凝剂。

The 0-40cm soil layer soil mean value looked that mixes by the interlacing broadcasts the lawn soil ulmin, the alkaline hydrolysis nitrogen content to be highest; The fast-acting phosphorus, the fast-acting potassium are highest by the unicast awnless brome lawn content; The colleague mixes broadcasts lawn pH to be biggest.

不同播种方式下土壤有机质、碱解氮、速效磷含量在0-40cm各土层内呈现随着土层深度的增加而降低的趋势，均以0-10 cm土层土壤含量为最大；同行混播和隔行混播草地速效钾呈现降低的变化趋势，单播无芒雀麦草地则呈现先降后增再降的变化趋势，以0-10 cm和20-30 cm土层土壤含量为最大，均为80，并与其它土层间达到极显著差异；pH则呈现出增加趋势。0-40cm土层土壤平均值来看以隔行混播草地土壤有机质、碱解氮含量最高；速效磷、速效钾以单播无芒雀麦草地含量最高；同行混播草地pH最大。

Home page is absent the first, major person thinks the website falls authority, when this lets exchange friendship to link very nerve-racking, others Site issues your website, if discovery is not in the first, some websites that say you with you fall counterpoised to be not done, some pays no attention to you directly.

首页不在第一，大部分人都认为网站降权，这个让交换友情链接的时候很伤脑筋，别人site下你的网站，要是发现不在第一位，有的就跟你说你的网站降权了不做了，有的就直接不理你。

The results were as follows: 1 at normal or high temperature, the selected asphaltene dispersant could reduce the association of asphaltene molecules, 2 hydrogen-transfer of FCC decanted oil and its sub-fractions were evaluated by using anthracene and 9,10-dihydroanthracene as chemical probes, one of sub-fractions could be taken as hydrogen-donor.

本文首先从渣油生焦的关键组分沥青质入手，为热处理降蜡筛选抑制生焦的添加剂，在生焦率低于0.1w%的前提下，提高热裂解降蜡的深度。

In situations where it is not possible to reduce the farrowing house temperature, consideration should be given to feeding diets with a reduced heat increment.

在无法降低产仔圈舍温度的情况下，应考虑饲喂能降低热增耗的日粮。

When the flag is half-masted, both flags are half-masted, with the US flag at the mid-point and the other flag below.

说清楚点：一是不是刚降了中间的国旗。还来不及降旁边的？然后就拍下了这样一张照片

While the oscillating flow cycle-averaged pressure drop for a Nylon wire screen regenerator is larger than that for a stainless steel regenerator, which is 3 to 5 times higher than that in a steady flow.

这一结果与其他相关文献的结论基本吻合。对於非金属蓄冷器，发现它的平均压降要大於金属蓄冷器的平均压降，是相同条件下稳定流动的3~5倍。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
