渐变

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.

最近，在南秦岭旬阳盆地下古生界铅锌矿集区内的志留系梅子垭组地层中首次识别出一条近东西方向延伸长达10余千米的钠长石沉积岩带，与地层整合产出，渐变过渡，厚层块状，条带状，角砾状构造，均粒微-细晶结构，内碎屑结构；其化学成分以富含SiO2，Al2O3及Na2O为特征，富Fe，Mn，贫Co，Ni，Cu等微量元素；该钠长石岩的∑REE，LREE，HREE均较围岩偏低，具明显Eu亏损的特征。

Leaves , stems and buds of colored-leaf trees are colorful , they are white, or yellow , or red, or orange etc., some colored-leaf trees are of two kind of colors, such as golden sprinkle in green leaves, or with golden edge, or different color in two faces of a leaf , some colored-leaf trees with leaves gradual changing amang yellow ,orange , red , purple.

彩叶树种的叶片、茎、芽等色彩丰富，或银色、或黄色、或红色、或橙色……有些彩叶树种表现出复色如洒金、镶边、异色等，有些体现出黄、橙、红、紫等色彩渐变过程。

Theoptimal conditions were as follows: amidulin 1.25%,CaCO_3 0.05%, yeast0.6%,NaC1 0.7%,KH2PO4 0.3%. The stability of antagonistic substance produced by Q6 was studied. Theactivity of the inhibitive substance was influenced when time and temperaturewaxing. In 100℃for 30 minutes,the inhibitive zone diminished distinctly, but thesubstance still had inhibitive effect on the pathgen. In pH 3.0～above 9.5 forovernight or treated by Proteinase K, the inhibitive zone is not changed.

对其拮抗物质进行了温度、酸碱度和酶三个方面的稳定性试验，当温度达到55℃以上时，随着温度和时间的变大，抑菌圈逐渐变小，但直到100℃，30min时，对病原菌的生长仍有抑制作用；pH3.0～9.5以上静置过夜后，拮抗物质对病原指示菌产生的抑菌圈几乎没有发生变化；经过蛋白酶K处理后，拮抗物质对病原指示菌产生的抑菌圈不变。

Recently, people already do many research to shotdetection. But it still have many issue not to solve due to video peculiarity, such ashow to confirm the accurate translate frame, how to detect the amphibolous gradualshot translation, how to select suitable automatic threshold, those still have auniversal effectively method.

近年来人们已经对镜头检测做了大量的研究，但由于视频的特性，镜头检测中还有很多问题没能很好的解决，例如如何确定精确的镜头转换帧，如何检测变化不明显的渐变，如何自动地选取合适的自适应阈值都还没有一个通用有效的方法。

So VEGF is an important reason during anamorphism of hepatocirrhosis.

这说明，在肝硬化渐变中，VEGF起着重要作用。

In this paper, a waveguide-based 1×2 power-combining structure at Ka-band using double antipodal finline-to-microstrip transitions is proposed, and the optimal tapers are analyzed by using spectral domain method.

The closed loop control system simulation was carried out based on ARX model and BP neural network prediction model to prove the feasibility of this method.

为了进一步验证该方法的有效性，设计了梯形、渐变哑铃形和突变哑铃形三种不同形状的工件，以代表实际焊接过程中不同的散热条件。

The measurement results show that the intensity increases rapidly with discharge voltage at a lower voltage range, but the speed slows at the higher voltage range, for constant gas pressure of 130 Pa; and the intensity increases backwardly with gas pressure at constant discharge voltage of 6.4 kV.

实验数据显示，保持气体压强p=130 Pa不变，在电压较低时，光谱强度随电压增长较快，在电压较高时，光谱强度增长较慢；保持放电电压U=6.4 kV不变，光谱强度随气压增长逐渐变小。

The results demonstrated that the fractional conversion and reaction rate were rapidly increased in the initial curing reaction. The higher the curing temperature, the higher the fractional conversion and reaction rate was. With increasing of the curing temperature and time, the fractional conversion and reaction rate decreased and became constantly. The initial curing reaction was a first order reaction. The apparent activation energy and frequency factor of curing reaction used G- capryl ester was bigger than that of used G-oligomer.

结果表明：固化体系在研究的固化温度下，转化率和反应速率在固化反应初期增加快速，温度越高增加越快，随着固化时间的延长，这种变化逐渐变慢，并最终趋于恒定；初期固化反应为一级反应，反应初期的表观活化能和指前因子大小顺序为G-预聚体＞G-辛酯。

After the study of the change of diversity, abundance and structure of foraminiferal faunas, three phases of the foraminiferal evolution have been recognized during the latest Cenomanian to Sa...

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
