The reaction mechanism between nickel ion and butynediols in the electroless plating process was analyzed. The results show that the change of BOZ concentration is a quasi first-order reaction, the change of the nickel ion concentration is related to the BOZ density, and this change belongs to a higher order reaction. The reaction rate equation was determined as dC/dt=-8.585×10^(-4)+1.188×10^(-4)t-4.64×10^(-6)t^2+5.8×10^(-8)t^3-2.3×10^(-11)t^4. The activation energy of this process decreases as temperature increases, and it decreases with the BOZ concentration as 64-423 mg/L, it increases with the BOZ concentration as 123~240 mg/L. The S value is positively correlated to temperature, when the temperature is 80℃, the reaction rate and S value are the largest; while when the temperature is above 80℃ and BOZ concentration is over 160 mg/L, S value and the reaction rate decrease gradually.

结果表明，镀液中BOZ浓度的变化是准一级反应，镍离子的浓度变化与BOZ的浓度有关，属多级反应，其反应速率方程为dC/dt=-8.585×10^(-4)+1.188×10^(-4)t-4.64×10^(-6)t^2+5.8×10^(-8)t^3-2.3×10^(-11)t^4，反应体系的活化能E随温度的升高而减少，随BOZ浓度的变化而变化：当BOZ浓度在64~123mg/L时，E线性减少；在123~240mg/L时E线性增加。S随温度的升高而增加，当温度达到80℃时S值最大，反应速度最大；当温度超过80℃，BOZ浓度大于160mg/L时，蝎的值逐渐减少，反应速度降低。

Website content, you whether to raise a website collect a page, add data bulk, and collect data wildly, such very short during it is pretty good, but such station is dropped very easily by search K, the database of the search often meets the content of a capture and him database content is compared relatively, the content that should discover you is similar or similar, light demote, depilate again, want to write the word that fills data, acquire as far as possible some of content related to the website, have alternative accretion, some of content that enrols a person to like major quite is copied on relevant website, had better add some achieve formerly, such more denounce search spider to like.

七、网站内容，你是否为了提高网站的收录页面，添加数据量，而疯狂采集数据啊，这样很短的期间是不错，但这样的站很轻易被搜索k掉，搜索的数据库经常会把抓取的内容与他数据库内容相对比，当发现你的内容相似或者相仿，轻则降级，重则拔毛，要想填充数据的话，尽量添置些与网站相关的内容，有选择性的添加，在相关网站上拷贝些比较招人喜欢专业的内容，最好添加些原创的，这样更讨搜索蜘蛛喜欢。

The results showed that there were two kinds of grains in the cells,one was large and had low electron density,Gl for short,while the other was small and had high electron density,Gh for short.The latter ones had a circle around it which can be seen through the microscope.During the aroma releasing period,the shape of the two grains changed distinctly,which led to the inference that Gl was the leucoplast,the store-room of aroma precursors or energe substances,and that the Gh was probably the lysosome which is related to the enzyme system?s aroma producing.The circle around Gh is the formed fragrant constituents and the aroma forming is the result of the interaction of Gh and Gl .

结果发现，茉莉花瓣细胞中存在电子密度较低、体积较大的颗粒和电子密度较高、体积较小的颗粒（分别简称为Gl和Gh颗粒），并在Gh颗粒周围存在清晰的晕圈；在茉莉花释香过程中，两种颗粒在形态上均发生明显的变化，推测Gl颗粒可能是白色体，是茉莉花香气前体物或能量物质的贮存器，Gh颗粒可能为溶酶体，与香气形成的酶系统有关，Gh颗粒周围存在的晕圈可能是香气物质，香气物质的形成是Gl和Gh颗粒相互作用的结果。

One reason is that the model is an algebra method and it is based on the theory of minimal element. It can give more credible proof. Another reason is that the model tries to prove security of protocols, rather than check them. Thirdly, the model is simple and easy to use, and proof can be finished by manual. Moreover, graphic description makes its proof more comprehensible. Fourthly, there is much research work related to the model, which gives me a good springboard.

A new picorna-like virus was isolated from dead Evtropis oblique larvae deceased from NPV infection. Electron microscopic observations of purified virions were non-enveloped isometric particles with diameter of 26nm. The virions contain two capsid proteins: 31.5kDa and 28.8kDa, the amount of later is 2.5 times more than that of the former. Analysis of 3′terminal sequence of EoPV clone identified that it can encode RdRp and has eight conserved motifs. Homology analysis shows that it is closely related to Perina nuda picorna-like virus.

The metal elements of the volcanic-hosted massive sulfide deposit have two sources, the copper and zinc are derived from rhyolitic magmas whereas the lead are probably related to old sediments overlying the rhyolites.(4) It is suggested here that the volcanic rocks hosting massive sulfide deposit in the north Qilian orogen, which are previously considered as a bimodal suite of Neo-proterozoic to middle Cambrian age in a continental rift, are virtually related to subduction magmatism in Ordovician age, and there might have no continental rift magmatism of Neo-proterozoic to middle Cambrian in the north Qilian.

Th/Ta比高(5.0～11.7)，εNd为较大的负值(-2.6～-8.4)，流纹岩的形成可能是两个端元组分混合的过程、或是上地壳混染的结果，形成在活动陆缘环境；(3)北祁连块状硫化物矿床成矿金属物质具有两种来源，Cu、Zn等来源于流纹岩，而Pb的来源可能与古老沉积物有关；(4)本文认为，前人厘定的北祁连新元古代-中寒武纪赋存块状硫化物矿床的大陆裂谷双峰式火山岩应是与俯冲作用有关的奥陶纪火山岩，说明北祁连可能不存在新元古代-中寒武纪的大陆裂谷活动。

The Paleoproterozoic Beidahe Group-complex remains as continental shivers in the interior of the North Qilian orogen. In its early stage of development, there occurred abundant amphibolite. The protolith of the amphibolite is basalts. The Alk-∑FeO-MgO plot, REE features and Rittmann index show that the protolith belongs to the calc-alkaline suite and exceptionally shows the subalkaline character. The rock is characterized by higher Al2O3 and ∑FeO and lower Mg#, indicating that it has a higher degree of compositional evolution and that the formation of volcanic rocks is related to activation of older crust. Highly fractionated REE patterns and amphibolite on the Ti-Zr-Y plot, Ni-FeO/MgO plot and Ta/Yb-Th/Yb plot all indicate the characteristics of volcanic arcs and active continental margins. On the geochemical diagram of basalt, the overall REE features are in the main analogous to those of calc-alkaline island-arc basalt, with Sr87/Sr86=0.71617–0.72033,Nd143/Nd144=0.512414–0.512495 and εNd=–2.79 to –4.37,εSr=245.78–305.3, showing that the magma was derived from the crust or subjected to contamination with the lower crust below the continent.

提要：以大陆碎块形式残存于北祁连造山带内部的古元古代北大河岩群早期发育有大量的斜长角闪岩，其原岩为玄武岩，Alk—∑FeO—MgO图解，REE特征，里特曼组合指数等均显示斜长角闪岩属钙碱性系列范围，个别显示弱碱性，斜长角闪岩具有较高的Al2O3，∑FeO和低的Mg#，这些特点反映其成分演化程度较高，表明火山岩的形成与古老地壳的活化有关，有较强分异的稀土元素分配模式，在Ti—Zr—Y图，Ni—FeO/MgO图解和Ta/Yb—Th/Yb图解上斜长角闪岩均显示火山弧或活动大陆边缘的特点，在玄武岩的地球化学形式图，稀土元素整体特征与钙碱性岛弧玄武岩基本相同；87Sr/86Sr=0.716 17～0.720 33， 143Nd/144Nd=0.512 414～0.512 495，εNd=-2.79～-4.37。

微波炉所用塑料器皿的彩釉含铅，但溶出的铅量与所盛放食品的 pH 值、烹调温度和时间有关。

The theory of Yin-Yang timely related was summariged by the ancient schoiars, Under the directing of the theory that man, as a macrocosm, is conerned with the macrocosm. It is the core of the theoretical system inthe canon of Medicine, and it reflect. the life rhythm which is synchronous with the change of human life activity and four seasons in the nature, embodys the concept of wholism that man and nature are united.

&时藏阴阳&理论是《内经》理论体系的核心，它是古人在&天人相应&思想指导下，通过长期的实际观察总结出来的，它反映了人体生命活动与自然界四时阴阳消长变化相同步的生命节律性，体现了人与自然的统一整体观。

SAGARU" has the meaning "Move Backwards" in Japanese V2 that express the direction of descent. This is due to the mechanism "Perception of the depth". On the contrary, the meaning "Move Backwards" is not included in the meanings of Chinese "V-sia". It appears it is because place noun related to "V-sia" expresses "SOURCE" excluding the limited places such as "Sea, river, water, well, and trap". Therefore, it is against the mechanism "Perception of the depth.

日文中表示下降方向之后项动词中「─SAGARU」可表示「后退」，这也是因为人类的视觉机制之一的「深度知觉」所造成的，相反地在中文的V下的意义中并没有「后退」这样的意义存在，这应该是因为与V下连接的处所名词除了像「海、河、水、井、陷阱」这些少数的场所之外皆为「起点」，也因为这样而不符合「深度知觉」这视觉机制。
