Thus the chemical composition of intermediate A is that of nickel nitrate tetrahydrate, that of intermediate B is of nickel nitrate dihydrate, that of intermediate C is of the monohydrate whilst that of D is anhydrous nickel nitrate.

因此，中间产物A的化学成分是四水硝酸镍，中间产物B的化学成分是二水硝酸镍，中间产物C的化学成分是一水化物，而中间产物D的化学成分是无水硝酸镍。

The Ni and Zn-doped spiculate α-FeOOH were prepared by the coprecipitation method and citric acid method using FeCl2、Zn(NO3)2、Ni(NO3)2 and NaOH as raw material and spiculate α-FeOOH as intermediate. Then they successively were enwraped by citric acid complex of the Ni and Zn and heat treated to get spiculate nano-Ni0.5Zn0.5Fe2O4. The particles size and slenderness ratio of spiculate nano-Ni0.5Zn0.5Fe2O4 were successfully controlled by the doped mass of Ni and Zn in the coprecipitation process.

以FeCl2、Zn(NO3)2、Ni(NO3)2和NaOH为原料，借助针状α-FeOOH做为中间体，有效的把共沉淀法和柠檬酸法相结合，制得掺有镍和锌的针状纳米α-FeOOH，在其表面包裹镍和锌的柠檬酸络合物后，经热处理制得了针状的纳米Ni0.5Zn0.5Fe2O4 ，并通过控制共沉淀法过程中镍和锌的掺入量，有效的控制了针状纳米Ni0.5Zn0.5Fe2O4 的粒径和长径比。

The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.

试验结果表明，长期在高温条件下服役，铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体，长期高温单边渗碳形成大量富铬碳化物，促使镍富集并起泡形成瘤状物，催化含碳气体的分解；表层瘤状物使辐射管表层疏松，表面积扩张，加快了碳向基体的渗入，提供了碳化物持续长大的条件，并引起沿碳化物周边开裂和奥氏体基体严重萎缩；合金元素的重新分布造成主合金元素铬和镍产生两极分化，镍和硅的富集促使石墨化，与侵入的氧形成内部氧化空洞和膨胀疏松，最终导致构件穿孔失效。

Our grab nickel production, nickel is mainly used to crawl Hard fine powder , red clay minerals such as highly viscous due to the recent nickel Hard fine powder , red clay and other minerals to be widely used, so Many major ports on the existence of such a problem, in which the ore handling when loading and unloading there is a low efficiency, has been a lot of ore grab adhesive wall, our company in order to solve this dilemma has been studied and produced by such a professional crawl very sticky ore grab, the principle is: grab the lowbeam calculated to increase the adoption of two pieces of solder, including the specific location of board and grab the bucket to create a circular flap, so Open grab discharging, the fight is on board, including the body wall from the top down (no contact with body panels Doo), to stick the body in fighting the viscous wall down, including mine, so, which greatly improved the handling grab the efficiency of ports and factories to solve the problem, which is purpuratus grab a patent, other manufacturers can not be produced.

我公司生产的镍矿抓斗，主要用来抓取镍矿、铁精粉、红粘土等粘性很强的矿石，由于近来镍矿、铁精粉、红粘土等矿石在被人们广泛使用，因此，许多大港口就存在着这样一个问题，在装卸这此矿石的时候，存在着装卸效率低，抓斗内壁被很多矿石粘着，我公司为了解决这一难题，现已研究并生产出来这种专业抓取很粘的矿石抓斗，原理是：在抓斗的下承梁上通过计算得出要加焊俩块括板的具体位置，并要把抓斗的斗瓣做成圆形，这样在抓斗打开卸料时，括板就在斗体内壁从上而下，把粘在斗体内壁的粘矿括了下来，所以，这就大大提高了抓斗的装卸效率，为港口和工厂解决了这一难题，这种抓斗是紫石的一项专利，其它厂家是无法生产出来的。

The 1%-Ni-doped TiO_2 calcined at 400℃has the best photocatalic ability.An indigo carmine solution of 10 mg/L was completely photodegraded in 50 minutes in the presence of as-obtained photocatalyst under visible light.A series of structure analysis,such as XPS,TEM,are employed to investigate the structure of the Ni/TiO_2 composite in details.The results indicate that at the lower temperature,instead of the simple interface compounding reported by some references,the Ni ions could be inserted into the crystal lattice of TiO_2,and form the innovative material.
