However, methods and references for difference equation are relatively less. The new method proposed in this paper transfer the complex boundary value problem into the existence and uniqueness of the solution of the linear equations. For linear case , we obtained the necessary and sufficient conditions for the existence and uniqueness of the solution for the BVP; For the nonlinear case ,we got a series of new sufficient conditions by using contraction mapping theory and cone theory .

而差分方程边值问题的研究方法和文献还很少，文中新的研究差分方程边值问题的方法是将复杂的边值问题求解转化为代数理论中的线性方程组解的存在和存在唯一问题；对线性情形，较容易地获得了边值问题的解存在以及唯一的充分必要条件，而对非线性情形，则通过压缩原理和锥理论等各种不动点定理，获得了一系列新的充分条件。

The MIDI standard identifies 18 instruments, including noise effects (e.g., telephone, air craft), with unique numbers. For example, 0 is for the Acoustic Grand Piano, 12 for the marimba, 40 for the violin,73 for the flute, etc.

We reviewed the progress in soil analysis for readily available nitrogen, phosphorus and potassium made in the last 20 years, such as the application of salicylic acid and test strip for nitrate analysis, Mason Jar for nitrogen analysis , malachite green for phosphorus analysis, and flow analysis for different element based on different reactions.

从文献检索结果和国内土壤氮、磷和钾测定的实际来看，我国在土壤氮、磷和钾测定方法研究、测定仪器的开发与生产方面与国外仍有较大差距，土壤养分测定工作的差距主要在以下几个方面：(1)研究人员少。

Both of the thermophiles were motile by means of lophotrichous flagella and had high growth rate on medium containing cellulose. Optimal growth occured at 60℃ for the two thermophiles and at PH 7. 5 for Y, PH 7. 37. 5 for W strain. Y strain produced yellow pigment in cellulose medium and had yellow-colored, round or watery colonies in cellulose agar. The colonies of W strain were white -colored and similar in form to that of Y strain. The mesophile, Clostridium sp. B, was motile with peritrichous flagella. The colonies grown on cellulose agar were white and round with slightly undulate margins. The optimal growth temperature and PH of B strain were 40℃ and 7. 0-7. 2, respectively. All of the three Clostridia fermented varieties of carbohydrates and in cellulose media produced the similar end-products: CO〓H〓, ethanol and acetic acid. The DNA compositions were 34 mol% for Y and B, 35 mol% for W strain.

嗜热菌y与w在含纤维素的培养基中生长迅速，其最适生长温度均为60℃；最适PHy为7.5，w为7.3-7.5.y菌在纤维素培养基中产生黄色，在纤维素琼脂中菌落为黄色并呈圆形或流动粥样。w菌落为白色，但形状与y菌类似，嗜温菌B在纤维素琼脂上菌落为白色，圆形，边缘呈微小波状，最适PH与温度分别为7.0-7.2和40℃，三支菌都可发酵多种碳水化合物，且在纤维素培养基中产生同样的产物：CO〓H〓，乙醇和乙酸，三者DNA组成分别是y为34mol%，w 35mol%，B 34mol%。

Diffusion coefficients for metol and p-benzenediol were 2.1×10 cm^2/s and 2.7×10^6 cm^2/s, respectively. The electrocatalysis mechanism has been studied. ATR-FTIR was used for the characterization of the ME/Au SAMs. The oxidation currents were linear in the range of 1.0×10^(-7)~1.0×10^(-4)mol/L for metol and 6.0×10^(-6)~6.0×10^(-4)mol/L for p-benzenediol, with the correlation coefficients of 0. 9992 and 0.9996 by differential pulse voltammetry, and detection limit 2.0×10^(-8)mol/L and 1.2×10^(-6) mol/L for metol and p-benzenediol, respectively.

Now, I don't want to give you the impression that I'm a great musicologist, but I'm a lot better than what I was described as for a long, long time; you know, people said I only knew three chords when I knew five…I feel that, you know, the enormous luck I've had in being able to make a living, and to never have had to have written one word that I didn't want to write, to be able to have satisfied that dictum I set for myself, which was not to work for pay, but to be paid for my work-just to be able to satisfy those standards that I set for myself has been an enormous privilege.

现在我可不想给一个我是伟大音乐家的映象，很长时间以来，我就一直比我被别人形容的要强太多了。比如当他们说我只知道三和弦的时候，我已经知道五个和弦了。。。。。。我觉得我非常幸运，可以演现场、对我不想写的歌一字不写、可以对我为我自己设定的要求感到满意--不为了钱而工作，而是他们为我的工作而付钱。BBC Radio 1采访。1994
