It belongs the kind of complex bridges because its liner changes usually and the weight condition is also complex, except bear moment and shearing force, there are larger torsion and doubled moment, as a result, crankle、warping and aberration would happen.

这种异形桥梁结构是受力很复杂的一种桥型，其线性变化多端，结构受力复杂，除承受弯距、剪力外，还有较大扭矩和翘曲双力矩的作用，即使外荷载的作用通过梁的剪切中心，也将发生弯扭组合变形，同时伴随有截面的翘曲和畸变。

When, for example, an enemy machine gun sets up somewhere within 75 to 200 yards of the defending line, and brings it under punishing fire, it will be eliminated in most cases by the enterprise of a firer with one of the heavier weapons, rather than by the mobile aggressiveness of two or three riflemen.

周口店北京人遗址位于北京市西南房山区周口店镇龙骨山北部，是世界上材料最丰富、最系统、最有价值的旧石器时代早期的人类遗址。1921年至1927年，考古学家先后三次在"北京人"洞穴遗址外发现三枚人类牙齿化石，1929年，又发现了北京人头盖骨化石，以及人工制作的工具和用火遗迹，遂成为震惊世界的重大考古发现。1930年在周口店遗址还发现距今约2万年前的山顶洞人化石和文化遗物。

We prove in this paper that topological entropy is zero, in systems of equivariant mapping, that systems of compression mapping, and systems of the homeomorphism of unit circle onto itself, while the toppological entropy is positive, that extensible mapping in the compact toppological metric space.

证明了在一般的紧致度量空间上，等距映射的系统，压缩映射的系统，单位圆上的自同胚映射的系统等的拓扑熵都为零，而可扩映射的系统有正的拓扑熵。

The research work done is presented as follows:Compound dewatering technique of vacuum tube well is an effective technology for solving the dewatering problems of aquitard and interface relict water according to physical simulation test and field test. The variation laws, such as degree of vacuum, pore water pressure in different strata, have been studied. The results show that there is a certain scope of influence of vacuum in strata, and the vacuum degree in the horizontal direction decreases gradually with the increase of the distance from the main well; the change law of degree of vacuum in the vertical direction increases firstly and then decreases with the depth of soil strata, and changes with different soil nature and depth; changes of pore water pressure in soil strata has also shown a similar law of degree of vacuum.

主要研究工作如下：通过室内物理模拟试验和现场试验均证明了真空管井复合降水技术用于解决弱透水层和界面残留水疏干难题的有效性；并且对不同地层中真空度、孔隙水压力等变化规律进行了研究，发现地层中真空度均有一定的影响范围，且真空度在水平方向上随距主井距离的增加而逐渐降低；在垂直方向上真空度随深度总的规律是先增加后降低，并随土层性质及深度的不同而变化；土层内孔隙水压力也呈现出与真空度类似的变化规律。

In addition to Blair's original description for comminuted fractures and fracture dislocation of the body of the talus, it also provided a functional and durable ankle joint in various lesions of the ankles.关键词, osteoarthritis , tuberculosis , rheumatoid arthritis , equinus deformity

我们的结论是：除了贝尔氏本人初期所提出的运用於距骨粉碎性骨折及骨折性脱臼外，贝尔氏踝关节固定术亦可运用於各种不同的适应病，而且可以得到一个有功能的且可以持久使用的踝关节。

Boehmeriae were studied, and the results indicated that the zoospores of P. boehmeriae could be inactivated obviously by irradiating with 30W ultraviolet light 50cm away from the culture dishes tested and that 95% germination of zoospores could be restrained by 30W ultraviolet light treatment for 40sec.The mycelium growth from mycelium discs of P. boehmeriae were inhibited mostly by 30W ultraviolet light treatment for 20min. Afterwards, the inhibitive rates were decreased with the rise of the treatment time, which showed that the mycelium discs of P. boehmeriae had produced flexibility to ultraviolet rays after being irradiated by certain dosage of ultraviolet light.

研究了紫外光对苎麻疫霉生物学特性的影响，结果表明，30W的紫外灯管距培养皿50cm照射处理对苎麻疫霉的游动孢子具有明显杀灭作用，紫外光照射40sec可以抑制95%的游动孢子萌发；紫外光照射20min对菌丝块的菌丝生长的抑制率达最大，以后随着处理时间增加，抑制率却有降低的趋势，说明苎麻疫霉的菌丝块，经一定剂量紫外光照射后对紫外线产生了适应性。
