A chromium free conversion coating at least equivalent in corrosion protective quality to conventional chromate conversion coatings can be formed on metals, particularly cold rolled steel, by a dry-in-place aqueous acidic liquid comprising: a component of anions, each of said anions consisting of at least four fluorine atoms and at least one atom of an element selected from the group consisting of titanium, zirconium, hafnium, silicon, and boron, and, optionally, ionizable hydrogen atoms, and optionally, one or more oxygen atoms; a component of cations of elements selected from the group consisting of cobalt, magnesium, manganese, zinc, nickel, tin, zirconium, iron, and copper; the ratio of the total number of cations of this component to the total number of anions of component being at least 1:5; sufficient free acid to give the composition a pH in the range from 0.5 to 5.0; a component selected from the group consisting of phosphorus-containing inorganic oxyanions and phosphonate anions; and a component selected from the group consisting of water-soluble and water-dispersible organic polymers and polymer-forming resins and, preferably, also including a component selected from the group consisting of tungstate, molybdate, silicotungstate, and silicomolybdate anions.

通过对包含以下成分的含水酸性液体进行干燥，可以在金属上形成无铬的转换涂层，该涂层与普通铬酸盐转换涂层相比，至少在抗腐蚀质量上等效：$_一种阴离子成分，所述各个阴离子包括至少4个氟原子，至少选自钛、锆、铪、硅与硼元素中的1个原子。任选地可离解的氢原子，任选地1个或多个氧原子；$_一种选自钴、镁、锰、锌、镍、锡、锆、铁与铜元素的阳离子成分，上述成分的阳离子总数与成分内的阴离子总数之比至少为1∶5；$_足够的游离酸以使该组合物的pH值在0.5～5.0的范围内；$_一种选自含磷的无机含氧阴离子与膦酸盐阴离子的成分；$一种选自水溶性与水可分散性有机聚合物与聚合物形成的树脂的成分，优选还包括一种选自钨酸盐、钼酸盐、钨硅酸盐与钼硅酸盐阴离子的成分。

In his first year as a Dodger (1991), Butler earned a roster spot on the National League All-Star team, and finished 7th in MVP voting. During the 1995 season, Butler was signed as a free agent by the New York Mets. In August 1995, Butler rejoined the Dodgers in a trade for Dwight Maness, and Scott Hunter. After finishing the season with the Dodgers, he again became a free agent and returned to the Dodgers.

在加入道奇队的第一年(1991)， Butler就获选明星球员，并且在年度最有价值球员的投票中排名第七。1995年间Butler被纽约大都会队签下，但是球季中道奇队利用Dwight Maness与Scott Hunter又将Butler换回道奇队。1995年球季结束后，Butler再度成为自由球员，他选择继续为道奇队效力。

Results The results showed that the total cantharidin contents in the samples of Meloidae were 1 to 9 times the free cantharidin contents. The total cantharidin contents were generally higher than 2.0% of dry body weight and the free cantharidin contents were all less than 1.7% of dry body weight in Mcloidac.

芫菁体内总斑蝥素的含量为游离斑蝥素含量的1-9倍，总斑蝥素的含量一般多于虫体干重的2.0%，而游离斑蝥素的含量均低于虫体干重的1.7%。

A Ni-Cu based cladding was thus deposited, where the powdered Ni1015 was provided for the laser cladding process to form a smooth surface layer bonded metallurgically with Cu substrate, whose grain-refining microstructure is homogeneous, compact, void-free and crack-free.

用5 kW CO2激光器，通过优化激光工艺参数，在结晶器用铜合金表面预置添加SiC晶须的镍基自熔合金(Ni1015)粉，制备出表面平整、组织均匀致密、无气孔和裂纹等缺陷、与基体为冶金结合的Ni-Cu激光熔覆层。
