Diacetyl is signal products of ripeness of beer fermentation and proper content of higher alcohols could make beer products full and mild in taste, but excessive higher alcohols not only bring beer peculiar smell but also make beer toxic and ebriety caused by alcohols, so superscale of diacetyl and higher alcohols had become restrictive factors and outstanding contradictions of improving beer qualities, especially in producing low cost beer products fermented by elevating fermentation temperature, shortening fermentation period and increasing content of subsidiary materials.

双乙酰也是啤酒发酵成熟的标志物质，过量的双乙酰给啤酒带来不愉快的"馊饭味"，而适量的高级醇可使酒体丰满圆润、口感柔和协调，但高级醇含量过高，不仅会给啤酒带来异杂味，还易发生醇类中毒，导致醉酒。因此，双乙酰和高级醇超量已成为制约啤酒质量的重要因素，特别是在提高温度、缩短周期、增加辅料的低成本快速发酵中，这一问题更加突出。

Although a mechanism that allow multi-user to edit the same data file can improve the data updating performance and promote the creating and cooperation of geographic data, the so-called version updating conflict problems that arise from the inconsistency of geographic data due to different editing behaviors must be considered beforehand.

一个允许多使用者同时更新同一地理资料档案的机制固然可提升资料更新的效率，并且促进地理资料的建置与分工，然而建置一个多使用者编辑之多版本地理资料库却也势必面临各种编辑者不同的编辑行为可能导致地理资料的不一致，而产生所谓的『版本更新冲突』。

同时，对造成这种状况的因素做了研究分析，农户的生计金融资本和劳动力资本的缺少是造成这种状况的内在因素；市场、制度和政策外部因素可直接或间接改变农户生计资产的配置状况，导致农户采取不同的生计策略。

Before, it was typical that each application used alone its own database due to the limitation of software tools of developing and technologies of application designing. In this case, repeated construction, lack of flexibility, inextensibility, not meeting users need to be changed and difficulty of maintenance were brought about.

在以往，由于软件开发工具和系统设计技术的限制，在系统建设中，都是一个系统一个库，这样就导致了大量的重复建设，而且系统缺乏灵活性，开发的软件几乎不具有可扩展性，不能适应用户需求的变化，维护起来也非常的困难。

The soil cutting experiment indicates that the interior friction angle and the shear intensity of soil is reduced;and the maximum principal stress is decreased due to the vibration load;it induces the decrease of digging resistance.

从理论上研究了振动掘削岩土的减阻机理，土壤剪切试验结果表明，振动载荷能够使土壤的内摩擦角变小、抗剪强度下降、最大主应力值减小，从而导致挖掘阻力降低；对土壤在静态载荷和振动载荷作用下的失效过程进行了对比仿真实验研究，可知土壤在振动加载的条件下强度显著下降，并提前于相同条件的静态加载而破坏，同时跟踪X方向的载荷发现，振动掘削最大掘削阻力可降低50%。

On the basis of Raman and FTIR spectra research on melt structure and water solubility mechanism in albite glasses, we can make the following conclusions:(1) Higher pressure (1bar-2. 0GPa) can lead to below frequency region (50-650cm〓) shift to higher frequency and become narrower, and result in high frequency region (850-1300cm〓) move to lower wave number and become narrower at the same time. These are consistent with the decrease of average T-O-T angle and distribution scope of bond angles (0). In addition, the intensity of 580cm〓 band decrease with increase of pressure and the changes are obvious while pressure is in the range of 0.8-1. 0GPa. And these result from the"collapse"of the planar three membered -containing rings within the glass structure.

通过对高温高压下钠长石熔体结构及水在钠长石熔体中溶解机制的Raman和FTIR光谱实验研究，可以得出以下结论：(1)随着压力升高(1bar-2.0GPa)NaAlSi〓O〓熔体玻璃Raman光谱的低频区(50-650cm〓)不断变窄并向高频方向移动，同时高频区(850-1300cm〓)不断变窄且向低频区方向移动，这表明随着压力升高T-O-T键角不断减小，并且分布范围变窄，T-O-T键角这种变化从而可使T-O键的力常数减小，导致键强减弱；另外，580cm〓谱峰强度随着压力升高不断减弱，并在0.8-1.0GPa时最为显著，这是由于在0.8-1.0GPa时包含的平面三元环结构的"垮塌"造成的。

With the development of Immunology, its theory and technique application in the field of Otology, it is known gradually that inner ear is not immuno- privileged organ, it has the capacity of immuno- response defence and regulation. In certain circum- stances, the tissue of inner ear may become an autoantigen, which stimulates immune response of inner ear, induces inner ear lesions, causes Autoimmune Inner Ear Disease . Investigation into the inner ear immunity has opened up a new way of studing uncertain inner ear diseases.

随着免疫学的发展，免疫学理论和技术在耳科领域日益广泛的应用，使人们逐步认识到，内耳并非免疫"豁免"器官，它具有免疫应答、免疫防御和免疫调节能力；在某些病理情况下，内耳组织可成为自身抗原，激发内耳免疫反应，导致内耳损害，引起自身免疫性内耳病，对内耳免疫学的探讨，已为不明原因的内耳病的研究开辟了新的途径。

Experimental results indicated tobacco seedlings became more vigorous while leaves exceeding 5cm were cut by 1/3, showing more obvious overcompensation responses, and these seedlings grew quickly after transplanted, there quality and production value were increased.

试验表明，剪叶时剪去5cm以上叶片的1/3有利烟苗产生超越补偿效应，可明显提高烟苗的成苗素质，促进烟株的早生快发，提高烟叶的烤后产值和质量；剪叶程度增加，明显降低烟苗成苗素质，抑制烟株的生长；不剪叶则导致烟株严重早花。
