The two existent general strategies of nanocrystal preparations are an organometallic synthesis based on the high-temperature thermolysis of the precursors13-19 or on a dehalosilylation reaction,20,21 and the synthesis in an aqueous medium using polyphosphates22 or thiols23-27 as stabilizing agents.

二个 nanocrystal 准备的存在一般策略是以先驱者 13-19 的高温度 thermolysis 或 dehalosilylation 反应为基础的一个有机金属的综合，20，21 和在以 polyphosphates 22 或 thiols 23-27 作为稳定代理人的一种水的媒体中的综合。

In many industries, a large electricity heating equipment, such as heat treatment for the heating furnace for melting metal protective resistance furnace and the different uses thermoregulation boxes, people need their temperature monitoring and control, using single chip them control not only has control of convenient, simple and great flexibility characteristics, charged with temperature and can significantly increase the technical indicators, which can greatly enhance the quality and quantity of products.

很多行业中都有大量的用电加热设备，如用于热处理的加热炉，用于融化金属的坩锅电阻炉及各种不同用途的温箱等，人们都需要对它们的温度进行监测和控制，采用单片机对它们进行控制不仅具有控制方便、简单、灵活性大等特点，而且还可以大幅度提高被控温度的技术指标，从而能够大大提高产品的质量和数量。

Acquisitions of 2001 2001 年的购并案 A few days before last year's annual meeting, I received a heavy package from St. Louis, containing an unprepossessing chunk of metal whose function I couldn't imagine. There was a letter in the package, though, from Gene Toombs, CEO of a company called MiTek. He explained that MiTek is the world's leading producer of this thing I'd received, a "connector plate," which is used in making roofing trusses. Gene also said that the U.K. parent of MiTek wished to sell the company and that Berkshire seemed to him the ideal buyer. Liking the sound of his letter, I gave Gene a call. It took me only a minute to realize that he was our kind of manager and MiTek our kind of business. We made a cash offer to the U.K. owner and before long had a deal.

就在去年股东会的前几天，我收到从圣路易寄来的一个大包裹，里面装了一块看不出做何用途的金属，包裹里还有一封信，署名 Gene Toombs-他是一家叫做 MiTek 公司的总裁，他解释说 MiTek 是专门制造这玩意儿的世界级领导厂商，也就是用来做屋梁的连接板，他进一步表示 MiTek 的英国母公司有意出售这家公司，他认为 Berkshire 应该是最合适的买家，我相当欣赏他写这封信的语气，所以当下打电话给他，几分钟的谈话，我就发觉他是属于我们类型的经理人，而 MiTek 也是我们想要的公司类型，于是我们报了一个价给其英国母公司，没多久后就正式成交。

First, we synthesized a new monomer,1-(3\'-aminopropyl)-4-acrylamido-1,2,3-triazole hydrochloride,via click chemistry and its block copolymer with NIPAM, PNIPAM-b-PAPAT,via RAFT polymerization.On the basis of the reaction between amine groups of the PAPAT block and glutaric dialdehyde,core cross-linked and shell cross-linked micelles with inverted structures were prepared at 25℃and 50℃,respectively.

借助于PAPAT嵌段上含有的氨基及PNIPAM嵌段的LCST效应，我们在其20℃和50℃的水溶液中分别制备了CCL胶束和SCL胶束，进一步地，我们利用由Click反应产生的1，2，3-三氮唑环对金属的强络合和稳定作用，分别对CCL胶束的内核与SCL胶束的外壳用金纳米粒子进行选择性修饰。

Then, it analyses the effects on some natural parameters such as alloy transfer coefficient, surfacing layers, welding current and arc voltage etc.. It confirms the fitting ageing technique. Also, it discusses the microscopic structural transformation back and forth ageing and the effects on hardness change of overlaying metal by some alloying elements including C, Cr, V, W, Mo, Ni, Mn, B, Re through OM, SEM and X-ray diffraction analyses. Finally the abrasive resistance, red hardness, thermal fatigue property and anti-high temperature oxidability are investigated in experimentation.

A multiplayer chip LC resonator was fabricated using planar inductor and parallel plate capacitor. Because lumped inductor has small Q value and there is stray parameter effect in high permittivity substrate, the Q value of chip LC resonator is not high. Resonators based on λ/4 stripline with end short circuited were designed and fabricated. Input and output pads, coupled to the stripline using gap-coupling capacitor, are in the same layer with the center conductive strip. This new structure is very convenient for manufacturing in comparison with the conventional structure.

采用间隙电容耦合结构实现的谐振频率为1.8GHz四分之一波长终端短路带状线单端口谐振器的Q值最大值为225，谐振频率为1GHz双端口谐振器的Q值为83，谐振频率和Q值与耦合间隙、带状线的厚度和耦合引线长度有关；二分之一波长带状线谐振器的Q值和四分之一波长相比较尺寸较大，由于导电带较长，造成金属的损耗增加，从而导致谐振器的Q值较低；带状线结构的谐振器频率调节困难，本文提出了改变接地端的宽度实现谐振频率的微调方法，可实现频率调节量约1.5%。

Hence, the welding machines to be used for short circuiting transfer, make use of a variable choke system which can be tuned for different wire sizes, The frequency of the metal transfer may be of the order of 50 to 200 per second.

因此， 用于短路的焊接的机器转移，利用可能被为不同的电线尺寸调试的一个易变的阻塞门系统，金属的频率转移可能具有50到200 每秒的命令。
