But the tragedies of Virginia Tech-and Columbine, and Nickel Mines, Pennsylvania, where five girls were shot at an Amish school last year-are not the full measure of the curse of guns. More bleakly terrible is America's annual harvest of gun deaths that are not mass murders :some 14,000 routine killings committed in 2005 with guns, to which must be added 16,000 suicides by firearm and 650 fatal accidents (2004 figures).

不过，枪支所带来的祸害，并不完全体现在弗吉尼亚理工大学及科隆布恩和宾夕法尼亚镍矿（去年5名女孩在一所教会学校遭枪杀）发生的悲剧上，更为触目惊心的是美国每年有很多人死于非大规模枪杀案--2005年大约有14000人死于枪击，此外还有16000人吞枪自尽以及650人因枪支走火不幸殒命（2004年统计数字）。

The same pontiff and, at his suggestion, the General of the Society of Jesus, Goswin Nickel, immediately invited Bolland to Rome, promising him a rich harvest of materials.

同时，教宗，在他建议下，一般的社会上的耶稣， goswin镍，立即邀请bolland到罗马，答应他一个收获丰富的材料。

Boric acid is used in nickel plating, and would presumably be a constituent of rinse water.

硼酸用于镀镍，大概也是漂洗液的一个组成部分。

Stem corrosion problem is to be paid more attention to the problem of accumulated rich production experience, often by nitriding, boride, chromium, nickel and other surface treatment to improve its corrosion resistance, corrosion resistance and wear abrasion performance.

阀杆防腐问题是被人们所重视的问题，积累了丰富的生产经验，常采用渗氮、渗硼、镀铬、镀镍等表面处理工艺，提高它的耐蚀性，气动控制阀耐蚀性和耐磨擦伤性能。

First we found some limitation lying in the chemical metathesis, especially in the controlling of the quality of the product and the velocity of the reaction. In the following research, we did some comparison experiment of synthesizing various nickel boride nanocrystal in the same principle, but by the two methods respectively.

另外，在试验过程中，我们逐渐发现了化学交换法的局限性，尤其在对反应进程和反应产物质量的控制方面的缺陷，并进一步通过分别用两种方法合成纳米硼化镍颗粒，合成原理相同，但反应产物相应发生较大变化。

The Jussi ore shoot is exceptional also in that it contains considerable amounts of millerite and bornite.

洁西矿结的另一特点，是它含有相当数量的针镍矿及班铜矿。

Vanadium, boron, nickel, silicon and other elements are present in very small amounts in the body.

钒，硼，镍，矽和其它元素存在於非常小的数额在体内。

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。
