多变化的

From many experiments conducted by the author on the dynamic behavior of soil inrecent years it has been found that the propagation velocity of elastic wave,shear modulus andthe coefficient of subgrade rigidity in homogeneous soil tends to vary with depth.

近几年来，作者在对土的动性能所作的多次实验中，发现匀质土中弹性波的传播速度、剪切模量、地基抗压刚度系数有随土层深度而变化的现象。

Over 58% of respondents forecast higher R spending in the next 12 months, as compared to the previous 12 months, with the highest forecast by North East Asian respondents (66%) and nearly half (48%) of respondents in the Americas do not expect any change in their R budgets.

与此前12个月的研发费用相比，超过58%的被调查者认为未来12个月中此项支出将有所增加，其中东北亚的被调查者中，有66%均认同此观点。然而，48%的美国被调查者称他们此后12个月的研发费用不会有太多变化。

The fast development of science technology makes the products and production equipment can outdate easily. The market quota or marginal profit can be "robbed" by rivals immediately. The life cycle of a product is much shorter. As the society becomes richer and richer, the characteristics of market demand can be concluded as small volume, diversification, and variability.

科学技术的飞速发展，使得企业产品和生产设备很快就会过时，所占有的市场份额或边际利润顷刻间被竞争对手"抢走"，产品寿命周期大大缩短；随着社会富裕程度的逐渐提高，市场需求将呈现小批量、多品类、易变化的特点。

Lower estrogen level in females and lower testosterone level in males have been proved to be risk factors for AS. But organisms regulation and responsion to sex hormone level is an exquisite and complicated process with individual difference. It is not so simple as imaged by externally regulate sex hormone balance to prevent or delay the occurrence of AS. Great disputes exist in whether supplement of sex hormone, especially estrogen, can delay the occurrence and development of AS.

女性低雌激素状态，男性低睾酮状态已被多个临床研究证实是AS的易患因素之一，但由于机体对性激素水平的调节以及机体对性激素水平变化的应对是一个相当精细和复杂的过程且存在个体差异，试图通过外在地调整性激素平衡来预防或延缓AS发生并非象想象的那么简单，人为地补充性激素尤其是雌激素能否延缓AS发生与发展目前存在着争议。

An artificial neural network model is set up to depict relation between the self-ignition duration and sulfur content, ash content,oxygen consumption rate,carbon monoxide as well as carbon dioxide generation rate of coal at different temperature of self heating process.

根据煤的硫分、灰分以及煤自燃过程中的耗氧速率、CO和CO2产生率等随温度变化的序列值与煤自然发火期之间存在的密切对应关系，建立了前向多层人工神经网络模型，用已有的煤自然发火实验数据对网络进行训练，得到了神经元间的联结强度，从而准确地表征这种对应关系。

Combining many subjects technological development,such as immunology, chemistry,radiation and shadowgraphy,thoroughly inquires the changeing relation of cells structure and funtion,furtherly clarifes the materials effect on cell,It is the developing direction in the future that evaluates the biotic materials compatibility in cedd-culturing method.
