In this paper we combining connecting tunnel project of Subway Line 4 at Xidan-lingjing bystreet in Beijing. To aim at the difficulties of building large-span connecting tunnels in the fine sand layer, through roads and underground pipelines, construction nearby buildings and other project difficulties. Using theoretical analysis, numerical simulation, field tests and other research methods to comprehensive and systemic research the stratum deformation mechanism and process control techniques of shallow excavation method, and a series of results were obtained. Firstly, use the stochastic media theory to analyze the stratum deformation mechanism, concretely analyze the analytic equation of surface horizontal displacement and deformation which were caused by the excavation of single-hole and double-hole tunnel, and further discussion on ground settlement, vertical deformation, surface horizontal displacement and horizontal deformation. Analyzing the main influence factors of surface displacement, and combined with practical work to proof the theory which was applied to shallow buried single-hole tunnel in fine sand layer was scientific.

Results The axial length of eyeball was gradually decreased during the adult years of life accompanying with the increases of corneal and lens refractive powers and a decrease of anterior chamber depth fur maintaining a emmetropia status, and the steepness and thickness of lens, shallowness of anterior chamber contributed to emmetropia by decreasing the refractive index of lens.

结果 随着年龄增大，眼轴逐渐变短，但同时伴有角膜、晶状体屈光力的增大及前房深度的变浅以维持正视状态，晶状体的增厚、曲率的变大及前房的变浅可能通过屈光指数的减小同样维持了正视状态。

The superficial blood vessels could cross two or more pulmonary lobules, and the pleural superficial blood vessels and the interlobular blood vessels were mutual transitional. The outlines of lobules composed of vascular networks were various in size and form, and the lobular septa were also different in depth. The subpleural arterioles could be divided into arteriole, terminal arteriole, precapillary arteriole and capillary in turn according to the branching sequence of themselves. The plate-like, sieve-like and web-like vascular networks occurred in the subpleural microvascular networks.

胸膜面浅层的血管可以跨越两个或多个肺小叶表面，浅层的血管可与小叶间隔的微血管之间相互移行；由微血管网形成的肺小叶的轮廓大小不等、形态各异，小叶间隔的深度也有所不同；胸膜下微动脉可根据逐级分支的顺序将其分为微动脉、终末微动脉、毛细血管前微动脉和毛细血管；胸膜下毛细血管网中可见板块状、筛网状和网络状血管网。

With maturity, the coat color may lighten, so that a born black may become any shade of gray from black to slate to silver, a born brown from chocolate to sandy. Blues and fawns also show shades from dark to light.

成熟以后，被毛颜色会变浅，出生为黑色的狗，颜色会变成不同深度的灰色：从黑色到蓝灰色到银色；出生为褐色的狗，颜色会变为从巧克力色到沙滩色等不同深度的颜色；出生为兰色和驼色的狗也会变成从深到浅不同深度色调的颜色。

In the course of the extension of subsoiling mini-till,small shar-ed subsoiler is screened from 8 kinds of tillage practices to carry outshallow plowing and interval subsoiling,shallow plowing is 7-8 cmdeep.and at the interval of 35 cm,the subsoiling is 20-35cm deep.Thus,the co-exitence of loose and compact tilths is created(ratiobetween the loose and compact tilths is 3:4).Owing to the unchan-ge of surface soil position,water,fertilizer,aeration and heat are incoordination,and yield increase is stable.when...

在试验推广深松少耕法的过程中，从八种耕作措施中筛选出用小铧杆尺深松犁，进行浅翻间隔深松，浅翻7—8厘米，间隔35厘米，深松20—35厘米，创造的虚实并存的耕层(虚实比8∶4)，由于表土位置不变，水、肥、气、热协调，增产效果稳定，种小麦、大豆平均增产分别为21.6%和15.5%；而且还有节省油料、降低成本，不用大量增添新的耕作机具的优点，并具有明显的抗旱、抗涝、防止土壤风蚀、水蚀的结果。

In this paper, we propose a new approach to spoken Chinese understanding which combines statistical and rule-based methods. In this approach, the semantic classification trees which are built by the semantic rules automatically learned from the training data are used to disambiguate key words related to the sentences' shallow semantic meaning, and then, a statistical model is used to extract the whole sentence's domain action.
