On the basis of the summarization of MCM-Cs main features and its assembly and packaging technologies, the paper puts stress on relatively deepgoing studies in practically advanced MCM-C assembly process technologies as gold ball wire bonding, IC chip gold ball stud bump making, IC flip chip bonding and underfilling, in high reliability MCM-C packaging process technologies as integral LTCC substrate packaging, hermetically metal sealing, and also in the basic technological process of MCM-C assembly and packaging. Later on, it presents the effectively engineering development of two high level actual module products--a high-density monolithic processor system MCM-C , a high-speed data collecting and processing system MCM-C. Lastly, it briefly introduces various common methods of quality inspection and reliability test of MCM-C assembly and packaging in engineering practice.

Patent, and then the blade-to-blade flow was computed by solving the two-dimensional steady Navier-Stokes equations, finally, overall performance and internal flowfield characterization were obtained and analyzed.2. As to radial matching between blade sections, preliminary investigations were developed from three aspects such as stall margin customizing technique, control technology of tip clearance flow, prediction model and control technology of corner separate.a On basis of reviewing on methods of achieving the goal of stall margin in design process of fan and axial-flow compressor, in conjunction of understandings on "Sweep/Dihedral", stall margin customizing technique was put forward; two-dimensional performance prediction method for stall margin customizing was developed, it can consider influences of radial stacking patterns of blade sections and axial distances between blade rows conveniently and rapidly.b A simple model for tip leakage mixing loss of unshrouded blades for compressible flow was presented.

二、叶片基元展向匹配方面，本研究从影响负荷最大化的叶身展向积迭注：原(来源：ABC论文35网www.abclunwen.com指掠弯是裕度定制的一部分，为方便论述，本文将此统一论述为裕度定制、叶尖间隙、叶片与端壁角区这三个最重要因素出发，探讨了各因素影响负荷最大化的机理，并由此给出了最大负荷设计过程中的技术措施和努力方向。1从掌控风扇/轴流压气机裕度方法回顾入手，探析了美国和俄罗斯裕度控制方法及相应特点，结合对&掠/弯&因素的认识提出了裕度定制技术：并开发了能够体现裕度定制思想的二维特性预估方法，可在二维层面下方便快捷地考虑以掠/弯为代表的叶片基元展向积迭以及叶片排间轴向间距带来的影响；2借鉴Denton关于不可压叶尖泄漏损失的理论分析，推导出适用于可压缩流动的叶尖泄漏掺混损失计算的基本关系式。

The area is small to the highest ( conversion efficiency 13 - 15%, some have achieved more than 20%) of monocrystalline silicon solar energy cell conversion efficiency, and output power is big, and stability is good, grows ( generally can reach more than 20 years ) service life, but the raw and processed material cost height, the weak light specific property is wronger, and production technology is complicated, hence the selling price is also higher; The polycrystalline silicon solar energy cell is basic identical with the function characteristic of monocrystalline silicon solar energy cell; The conversion efficiency of non- brilliant silicon solar cell than hangs down ( simples about 6 - 8%), the area is than greatly, but because of his raw and processed material cost than hanging down, can be easy to big area industrialize production, what will have hope to be used the generally big area to generate electricity from now on most will be this kind of application that battery is along with manufacture technique and new material, in a single day the practical package photoelectricity conversion efficiency of its big area achieves more than the 10-15%, and the price of every tile electric power-generating equipment is fallen 1 - 2 U.S.dollar of time, and just is enough to that the solar energy cell efficiency that big area the getting extensive use will constantly replace in now convention certainly special use and the laboratory of sources of energy s will high get many.

单晶硅太阳能电池转换效率最高（转换效率13～15%，有的已达到20%以上），面积小，输出功率大，稳定性好，使用寿命长(一般可达20年以上)，但原材料成本较高，弱光特性较差，生产工艺复杂，故售价也较高；多晶硅太阳能电池与单晶硅太阳能电池的性能特点基本相同；非晶硅太阳能电池的转换效率较低（约6～8%左右），面积较大，但因其原材料成本较低，可便于大面积工业化生产，今后最有希望用于一般大面积发电的将是这种电池。随着制造技术和新材料的应用，一旦它的大面积实用组件光电转换效率达到10-15%以上，每瓦发电设备的价格降到1～2美元时，便足以大面积得到广泛应用并将不断取代现在常规能源。当然特殊用途和实验室中的太阳能电池效率要高得多。
