Similarly, the AMR begin to increase and then decrease with increasing the thickness d of the seed layer, and has a maximum value at a critical thickness d of 5.32nm. Compared to the permalloy films deposited on Ta seed layer ,the AMR enhancement of 10%-46% is observed in the permallay films deposited on (Ni0.82Fe0.18)1-xNbx seed layer.(2) The coercivity Hc1 obtained for magnetic field H applied paralley to the easyaxis is large than Hc2 for H applied perpendicular to the in-plane easy axis, and both of coercivity are consistent with the change of x.

2沿样品易轴方向的矫顽力Hc_1比难轴方向的矫顽力Hc_2大，两者随Nb原子的百分含量x的变化是一致的，饱和磁化强度Ms随x的增大先增大后减小，在x=27.1％处，Hc_1和Hc_2都比较小，而Ms则达到最大；种子层厚度d不能明显改变坡莫合金薄膜的磁性能；与以传统材料Ta为种子层的坡莫合金薄膜相比，以Ni_(0.82Fe_(0.18)_(0.829)Nb_(0.271)为种子层的坡莫合金薄膜的矫顽力只有轻微减小，但是Msg 以w讪Fq.t）lkNk为种于层的坡莫合全薄膜的各向异性戳电阻及磁性能研究却要大，mk坡莫合金层厂度！

The author considers that improving the resistance against pulverization and against corrosion of alloy is the direction for raising the durability of alloy electrode material.

提高合金在非钝化条件下的抗腐蚀性及抗粉化性是合金化改善合金循环稳定性的方向。

The present Cu-20Ni-25Co alloy forms a continuous of Co2O3 layers over the surface of alloy because Cu-20Ni-25Co alloy formed by adding Ni to Cu-Co alloy decrease the critical concentration of forming reactive component oxides.

这主要归因于向Cu-Co合金加入了第三组元Ni，降低了合金表面活泼组元形成氧化物所需的临界浓度，促使合金表面由混合氧化物膜向单一活泼组元氧化物膜的转化。

Using JDM-30 strain gauge measurement and 4192A impedometer, effect of magnetization field and stress on the magnetostrictive properties d33, k33 and μ of the Fe83Ga17 alloy are measured.

The ballistic experiments of tungsten long-rods penetrating composite laminates and steel target are investigated. The experimental results show that the penetration performance of torqued long-rod is stronger than that of non-torqued rod.

本文首先进行了钨合金杆弹侵彻有限厚度的钢靶和复合靶的侵彻实验，实验结果表明预扭转钨合金杆弹侵彻贯穿能力比未扭转钨合金杆弹要高。

The amount of Ni and Cr released from specimens coated with gold was much fewer than those from unplated specimens (P .05), which meant the stability of Ni-Cr alloy on the surface was improved. The biocompatibilities of gold-coated Ni-Cr alloy were better than the uncoated alloy, though there was no difference in biological ranking.

说明其耐电化学腐蚀能力明显提高；镀金后镍铬合金试件的镍离子、铬离子析出量降低，表面稳定性有了显著性提高；无氰镀金法镀金的镍铬合金生物相容性良好，从数据上比较优于未镀金镍铬合金，但生物学评级上无显著性差异。

The alloy was prepared through melting gold, silver, palladium, tin, indium, ruthenium, zinc, germanium in the high frequency induction furnace protected by argon and then deaerating the crude alloy at vacuum.

在参考国外配方和大量成分筛选的基础上，最终确定的烤瓷合金成分为Au70.7wt％Pd11.8wt％Ag13.9wt％Sn0.5wt％In3.0wt％Zn0.1wt％及Ge和Ru。合金主要特点如下：（1）合金不含Ni、Cd、Be等有毒元素，生物安全性良好。

And the strengthening mechanism can be described as follows: WC cemented carbides have interlaced short-clubbed grain, and in the bend strength test, the microcrack generates at WC/WC grain boundary, and may be blocked by interlaced fine-clubbed grains during extending, which induce the intergranular pulling-out. Due to the pulling-out mechanism, fracture-extend energy is greatly expended, thus bend strength is increased. The wear mechanism is groove wear and spalling of WC grains.

热机械合金化合成的WC-Co硬质合金比传统方法制备的同类WC合金具有更高的强度，其机理是：热机械合金化合成的WC合金具有交替排列的短棒状组织，在三点弯曲试验中，微裂纹萌生于WC/WC晶界位置，受到交错排列的短棒状晶粒的阻碍，裂纹扩展以短棒状晶粒的拔出方式进行，极大地消耗了裂纹扩展的能量，从而提高了弯曲强度；合成试样的摩擦磨损过程以犁沟磨损和WC颗粒的剥落为主要特征。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
