Then considering earth rotation and 6-DOF movement,the expression of absolute velocity and absolute acceleration for vehicle centroid are deduced by using transform of vector derivative.

与陆基固定垂直发射条件不同的是，潜射弹道式飞行器是在运动着的潜艇这样的动基座上进行发射的，为了保持发射时潜艇的可操纵性以及发射后使发射艇尽快离开发射位置，发射艇要有一定的速度。

The immunoregulation activity of SPG-1 mainly existed in the part of sugar chain, but keeping its molecular structure intact had some effects on its immunoregulation activity; SPG sulphation had reducing effects on the immunoregulation of SPG-1, whereas, after medium and low acetification of SPG, the immunoregulation of SPG was enhanced. Conversely after high acetification, the immunoregulation of SPG-1 decreased, that is, after introducing sulfuric and acetic acid base in SPG-1, its immunoregulation changed. All of these indicated the structure of SPG-1 was closely connected with its immune activity.⑤.

甘薯糖蛋白SPG-1的免疫调节活性主要在其糖链部分，但保持分子结构的完整性对其免疫调节的活性有一定的作用；甘薯糖蛋白硫酸化对甘薯糖蛋白SPG-1的免疫调节有降低作用，而中、低度乙酰化后，可提高甘薯糖蛋白的免疫调节作用，高度乙酰化后则降低其免疫调节作用，即甘薯糖蛋白引入乙酰基和硫酸基团后，其免疫调节活性发生了改变，这些均表明了甘薯糖蛋白的结构与其免疫调节活性有密切的关系。

The upper mounting block (140) has a socket (148) for holding a tow bar (80) and slots (170A/170B) for mounting a luggage carrier (70), both of which have legs (78A-F) which are lockably inserted into receiving slots (90A-C) in the stirrup members (92A/92B).

上方安装块（140）有一保持一牵引杆（80）用的插口（148）和安装一行李载重架（70）用的诸狭槽（170A／170B），它两具有可锁定地插入支座件（92A／92B）上的诸接收狭槽（90A－C）内的诸支腿（78－F）。

Since 2003 year, in two major ways, funds and lands have the governments macro-controlled the whole industry in order to keep the estate industries healthy and sustainable growth and evade the risk. Since funds and lands are the understructure upon which the estate companies have developed, the government control concerning them have made the whole industry faced a critical financing hardship. Consequently, many companies which used to extremely depend on bank credits are confronting the financial pressure. Many middle and small enterprises are even facing the problem of maintenance. Accordingly, under the background of the present macro-control, the debates and research over the diversity of estate companies' financing mode are abundant in its realistic meaning.

为了保持房地产行业健康、可持续发展，规避房地产金融风险，我国政府自2003年以来主要从资金和土地两个方面对房地产行业进行了宏观调控，由于资金和土地是房地产开发企业赖以生存的基础，多管齐下的调控措施打破了房地产开发企业原有的开发模式和融资模式，使得房地产开发企业普遍遭遇融资困境，过去以银行贷款为主要融资方式的房地产开发企业普遍面临资金压力，许多中小型房地产开发企业甚至面临生存问题，因此，在当前宏观调控背景下，探讨中小型房地产开发企业融资模式多元化问题具有很强的现实意义。

A backing bar assembly (20) has a plurality of positively positionable backing bar units (40) which are retained within an inverted U-shaped housing by semi-cylindrical lifters (68) which are adjusted by adjustment screws (60) connected to the housing.

一种靠背梁组件(20)，具有多个通过半圆柱形的提升机构(68)保持在一个倒置U形的腔室内的可适当定位的靠背梁单元(40)，提升机构通过与腔室相连的调节螺丝(60)进行调节。

可以方便地保持对从 CD 光盘到其它媒体拷贝的音乐文件的跟踪，并且在Report Writer 当中的媒体列表报告当中显示了在可重写音乐混合上花费的时间。

Article 144 The Government of the Hong Kong Special Administrative Region shall maintain the policy previously practised in Hong Kong in respect of subventions for non-governmental organizations in fields such as education, medicine and health, culture, art, recreation, sports, social welfare and social

第一百四十四条香港特别行政区政府保持原在香港实行的对教育、医疗卫生、文化、艺术、康乐、体育、社会福利、社会工作等方面的民间团体机构的资助政策。原在香港各资助机构任职的人员均可根据原有制度继续受聘。

George Bush, son of a Republican congressman from Texas, was certainly not the kind of young man likely to oppose the war. He chose to enter the Texas Air National Guard, where he was in a part-time flight training program that kept him associated with the military yet also safely distant from Vietnam.

小布什，得州共和党议员的儿子，当然不会是那种可能反对战争的年轻人，他选择了参加得州空军国民警卫队，在那儿接受非全天的空中飞行训练，这使他保持了与军队的联系，可又很安全地远离越南。

In real terms, this means that the 6.8mm SPC has the same relative trajectory as the 5.56mm (which allows for the M468 to be fired and treated essentially like a 5.56mm M-16), but with 50% more stopping power, and a bullet speed of 2650 feet per second from a sixteen and one-half inch barrel, delivering 1715 foot-pounds of energy, with a six hundred meter effective range.

这意味着6.8毫米SPC彈藥在保持与5.56毫米彈藥相对相同的弹道的同时却拥有多出50%的停滞能量，而这样一枚弹丸由一根16英寸半长的枪管中射出时，秒速高达2650英尺，释放1715尺磅能量，并且其有效射程可达到600米（如果M468可以在基本上像M-16一样射击、处理5.56毫米枪弹以作为对比的话）。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
