The invention also relates to a nozzle body (31) comprising a nozzle outlet which is disposed on the combustion chamber side end thereof, a nozzle needle (33) which is arranged in an axially displaceable manner and/or which can is actuated in a longitudinal recess (32) of the nozzle body (31); a throttle disk (25) which is arranged between the nozzle body (31) and the control valve (20) and which is closed on the rear end (oriented away from the nozzle outlet) of the longitudinal recess (32). Said throttle disk forms an opening stop for the nozzle needle (33) which co-operates with the rear front surface (orientated away from the nozzle outlet) of the nozzle needle (33) and defines the opening stroke of the nozzle needle (33), and a control chamber (45) formed between the rear nozzle needle front surface and the throttle disk (25), said control chamber being hydraulically connected to a pressure connection (29) which is used to supply fuel.

During the process of the fore mentioned analyses, some tentative works as follows were done.(1)On the basis of the fundamental of spatial analytic geometry, the basic method for displaceable block searching was put forward and the relevant program was written. With this program one can easily search out all the displaceable blocks and omitting of blocks, which is very common in searching blocks manually, can be avoided.(2)The coefficient of stability of blocks with failure mode II-2(that is, sliding on a single sliding surface, but confined by near intersecting line )was deduced.(3)The multi-cavern effect of Laxiwa underground caverns was studied on the assumption that all of the caverns were full face tunneled at the same time.(4)The stability classification scheme of rock mass surrounding large scale underground caverns was established. In addition to inherit the merits of the method of engineering geological

在完成上述工作的过程中，本论文主要在以下几个方面进行了一些探索：①基于空间解析几何原理，提出了块体搜索的基本思路并编制出相应的程序，基本实现了块体搜索的自动化，既大大缩短了块体搜索时间，又能防止因人工搜索引起的遗漏；②推导出Ⅱ-2型(单滑面滑动，但受侧限面约束)块体的稳定性系数计算公式；③以数值模拟方法论证了拉西瓦地下厂房洞室群全断面一次开挖时群洞效应的具体特点；④以岩体质量、开挖效应、群洞效应和次生灾害效应为评价指标，建立了&大型地下洞室群围岩稳定性分类&方案；该方案既继承了水电行业规范&围岩工程地质分类&法的优点，又综合考虑了大型地下洞室群的工程特点。

Results Masses were located at the branch of common carotid artery,so the interval between external and internal carotid arteries was enlarged.Low echoic substantial masses with clearly boundary were found.The bigger masses always grew around carotid arteries.More color flow signals were detected in the masses and most were arterial flow.

结果 颈动脉体瘤肿块位于颈总动脉分叉处，颈内及颈外动脉间距增宽，瘤体常呈实质性低回声，边界清晰，较大瘤体常围绕血管生长；彩色多普勒超声显示肿瘤内丰富彩色血流信号，以动脉血流为主，能显示瘤体与颈动脉的关系。

Haploid spores are mostly, but there are a small number of diploid , such as the brown algae and some species of Ectocarpus are still on the sporophyte produces diploid mitosis after the swimming spores, which germinate directly to produce sporophytes.

孢子大多为单倍体，但也有少数为二倍体，如褐藻中的水云等一些种类还在孢子体上经过有丝分裂产生二倍体的游动孢子，它直接萌发产生孢子体。

In this paper, cholinergic neurons was mapped in the two kinds of birds (Emberiza rutila and Fringilla montifringilla) by using immunohistochemical method.The soma size and cell density of cholinergic neurons in the three song control nuclei, the higher vocal center, the robust nucleus of the archistriatum and area X, were measured and compared. Here we discussed the distribution of cholinergic neurons and their effect on the process of song producing and song learning.

本文以中国北方地区常见的两种鸣禽栗鹀和燕雀为材料，应用免疫组化方法，对两种鸣禽发声控制核团，即上纹状体腹侧尾核或高级发声中枢、古纹状体粗核、X区内胆碱能神经元的胞体大小和胞体密度进行了观察测量，旨在探讨胆碱能神经元在发声控制核团内的分布情况及其在鸣啭产生和学习过程中的作用。

Epiphytic bacteria were isolated from sporophytic thallus collected from Qingdao and Dalian or gametophytic filaments stored in our lab of Laminaria japonica. Identification was done using both traditional physiological and biochemical way and molecular method. Phylogeny tree was established based on 16S rRNA gene sequence analyses, and some sequences of epiphytic strains from both sporophyte and gametophyte were different from all the sequences already exit and could be the new species.
