The changing climate first affects the structure of alpine timberline at an autecological level, and further affects the movement of the timberline as a whole.

气候变化首先从个体的水平影响林线的内部结构，然后才影响到作为整体的林线的推移，因此研究乔木个体生理活动与气候条件之间的关系，对于研究高山林线对气候变化的响应具有重要意义。

Having noticed that the number indicating the greatest depth was apparently in the centre of the map, I laid a rule on the map lengthwise, and then breadthwise, and found, to my surprise, that the line of greatest length intersected the line of greatest breadth exactly at the point of greatest depth,notwithstanding that the middle is so nearly level, the outline of the pond far from regular, and the extreme length and breadth were got by measuring into the coves; and I said to myself, Who knows but this hint would conduct to the deepest part of the ocean as well as of a pond or puddle?

发现那记录着最大深度的地方恰恰在湖心，我用一根直尺放在最长的距离上画了一道线，又放在最宽阔的地方画了一道线，真使人暗暗吃惊，最深处正巧在两线的交点，虽然湖的中心相当平坦，湖的轮廓却不很规则，而长阔的悬殊是从凹处量出来的，我对我自己说道，谁知道是否这暗示了海洋最深处的情形之正如一个湖和一个泥水潭的情形一样呢？

The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

骨肉瘤基本影像表现为骨质破坏、骨膜反应、瘤骨和软组织肿块。49例X线表现为成骨型19例，溶骨型13例，混合型17例；X线对骨质破坏、骨膜反应、软组织肿块、瘤骨和Codman三角的检出率分别为61.2%、95.9%、71.4%、73.5%和27.7%；10例CT表现均可见骨质破坏、软组织肿块及瘤骨，CT对骨膜反应、筛孔征和Codman三角的检出率为90%、90%和11%；CT对显示细小肿瘤骨和筛孔征最敏感，但对Codman三角的显示不如X线平片；32例MRI表现为骨髓腔内正常的骨髓高信号被肿瘤信号所取代，T1WI呈低～等信号，T2WI呈混杂信号，7例合并出血，24例中央坏死囊变，32例增强扫描均呈不均匀强化及瘤周可见水肿区。

Mathematical model of the cavity of three-tipped cycloidal pump was established, and the structure and characteristics of the novel three-tipped cycloidal pump were analyzed.

论述了三尖摆线的形成及其参数方程，并付其特性进行了研究，建立了三尖摆线泵型腔的数学模型，分析了新型三尖摆线泵的结构和特性。

On the basis of analyzing the characteristics of new typed FA planetary transmission of cycloidal needle-wheel, a set of force bearing analysis theory of tooth surface with the modification of tooth profile of cycloidal gear was put forward.

在分析FA新型摆线针轮行星传动特点的基础上，提出了一套摆线轮齿形修形下的齿面受力分析理论，并采用MARC工程软件对针齿和摆线轮齿面的接触状态进行了有限元分析，结果证明了受力分析理论的正确性。

These are thread objects corresponding to "alien threads", which are threads of control started outside the threading module, such as directly from C code. Dummy thread objects have limited functionality; they are always considered alive and daemonic, and cannot be join ed.

有线程对象对应于alien线程，这种线程有线程模块外面启动，例如直接调用c代码Dummy线程对象有被限制的个功能，通常他们都是活的和守护的，并且不能被joined。

The results showed that: 1 The survival curve of the population conformed to the type of Deevey-Ⅲ; 2 With an increase in the population mortality ratio and a decrease in the survival rate, the mortality ratio greatly increased in ages 0-40 years, reaching 89.7%; 3 There existed two peaks of mortality in the lifespan, one was from seedlings to young trees (0-40 years) and the other in the adult stage (180 years).

结果表明：1岷江上游林线地段岷江冷杉种群存活曲线趋於Deevey-Ⅲ型。2林线地段岷江冷杉种群生存率呈单调下降趋势，生存率下降趋势前期高於后期，说明岷江冷杉种群幼苗死亡率高，种群后期比较稳定。3林线地段岷江冷杉林整个生长期中出现了两个死亡高峰期，一个出现在幼苗向幼树过渡时期（0~40年），另一个出现在中龄时期（180年）。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
