The prevalence and abundance of the acanthocephalan exhibited very similar and significantly seasonal change patterns in O. uncirostris and H. bleekeri bleekeri. The infection levels were higher in autumn and winter, but lower in spring and summer. However, the infection levels in Z. platypus kept stable all the year round. There were significant differences among the overall abundance of the acanthocephalan in the three host populations. Nevertheless, the frequency distribution of the parasite in the three kinds of fish was over-dispersed in most seasons and in total as measured by the variance to mean ratio. The variance to mean ratio was not found related to the infection levels.

在感染率和感染丰度方面，寄生于马口鱼和油的木村小棘吻虫呈现出显著的季节变化：秋冬季节感染率和感染丰度都比较高，而春夏季节则比较低；与此不同的是，寄生于宽鳍鱲中的木村小棘吻虫则全年都维持着较稳定的感染水平；木村小棘吻虫种群在三种宿主体内的总体感染丰度差异显著，但都呈聚集分布，三者的方均比与感染率和感染丰度之间无显著相关关系。

Thischaracteristic of Atriplex canescens is consistent with that of many local species. TheLCP of Atriplex canescens in different treatments (light, medium, no and heavy watersoil stress) are 314.8μmolm~(-2)s~(-1)、272.5μmolm~(-2)s~(-1)、176.7μmolm~(-2)s~(-1)、143.1μmolm~(-2)s~(-1), respectively, which indicates that the LCP of Atriplex canescens is reducingwith the escalation of soil water stress. This tendency is favorable for Atriplexcanescens under drought stress to maintain certain photosynthesis even in weaksunlight so as to ensure the survival of itself, and keep balance between maintainingwater content inside and its photosynthesis.

四翅滨藜在不同土壤水分胁迫下的光补偿点：轻度土壤水分胁迫、中度土壤水分胁迫、无土壤水分胁迫和重度土壤水分胁迫下的光补偿点分别为，314.8μmolm~(-2)s~(-1)、272.5μmolm~(-2)s~(-1)、176.7μmolm~(-2)s~(-1)、143.1μmolm~(-2)s~(-1)，说明四翅滨藜的LCP随着土壤水分胁迫的加重而呈现降低的趋势，这种变化有利于处在干旱胁迫中的四翅滨藜在光强较弱的条件下仍然能维持一定的光合作用，以满足植物自身生命活动所需，同时也可以使植物在保持体内水分和进行光合作用之间寻找平衡。

By testing the free response of MRE, the eigenfrequency and the attenuation factor of the structure were obtained.

实验结果指出，实验结构的无阻尼固有频率和MRE的剪切模量随着磁场的增加而增加直到磁饱和；实验结构的阻尼比和MRE的损耗因子随着磁场的增加极缓慢的减小；MRE在磁场作用下，剪切模量变化最大为60％。

Then the experiment of the thickness and deviation dependent shows the continue networks model is more seemlier, in which the amorphous lattice is the same of a single crystal, but its bond distance and bond angle have a little change.

而我们的池厚与分散度关系的实验已说明了厚池中键长键角不归一，当小球标准差为8.4％时，键长键角的变化可以用连续网络的非晶模型来描述，此模型的非晶结构的骨架与单晶相同，但键长键角有小量的无规性。

Methods①The minimum inhibitory concentration and the minimum fungicidal concentration of citral against C.

方法①参照NCCLS M27A方案中的微量液基稀释法测定柠檬醛和氟康唑对原始白念珠菌的最低抑菌浓度和最低杀菌浓度；②采用多步诱导法，观察在含梯度浓度(1～50MIC)柠檬醛培养基上连续转种的白念珠菌MIC的变化情况，以氟康唑作为阳性对照，同时设空白对照和溶媒对照；③将敏感性下降的诱导株在无药培养基上连续转种10次后，检测其MIC值；④测定柠檬醛对氟康唑敏感性下降诱导株的MIC值。

Methods Through their treatment and concrescence,125 cases of floating knee injury were analyzed retrospectively,and the different treatment and time were selected according to their different typing and fracture position,and then decide functional exercise after operation according to this plan.

回顾分析125例浮膝的治疗及愈合情况，得出不同的分型及有无合并伤，选择不同的治疗方法和时机，并由此决定术后功能锻炼的时间和方法，因而对日后膝关节功能的恢复和受伤初期全身情况的变化产生不同的影响。

It greatly enhanced the damping force of shock absorber and it is convenient to replacing the foam metal inside this typed shock absorber and it is possible to replacing foam metal of different structure according to different requirements of damping force.

由于该种减振器的阻尼力在一定范围内可由外部磁场快速无级调节，而且这种变化是瞬时可逆的，因此近年来对它的研究和应用开发得到了相当的重视。

The frequency-dependent sensitivity coefficients with respect to the parameters of the radial layers are computed quantitatively. Comparing the horizontal permeability with the vertical permeability, the horizontal mobility plays the predominant role over the entire frequency range. The Stoneley wave is more sensitive to the velocity of the horizontally propagating SH wave than the flexural wave.

利用灵敏度曲线定量研究了不同频率下地层各个参数对相速度和衰减系数的贡献大小，主要结果显示模式波的衰减受水平渗透率影响明显，而垂直渗透率的变化对模式波几乎无影响；斯通利波对水平向传播的横波速度比弯曲波的灵敏度高。

The results indicate that MM5 has effect on predicting the strong clear-air turbulence, but no effect on predicting the thunder storm. The beginning and ending time, strength variation tendency and wind direction of the strong clear-air turbulence can be forecasted well by mesoscale model.

结果表明，中尺度模式对雷雨大风基本无预报能力，但对晴空系统性大风有很强的预报能力，模式可以对晴空系统性大风的出现时间、强度变化趋势和风向提供较准确的预报，对晴空系统性大风的结束时间也有一定的预报能力。

We show that the atomic c.m motion dont affect the atomic spectrum phase sensitivity when there is no correlation between atomic cm. motion and the field. With the increase of the average energy for atomic cm. motion, the peaks of the emission spectrum move towards each other, their heights change according to the state of the field and atomic motion. While there is correlation between atomic c.m.

当原子质心运动与光场无关联时，原子质心运动不影响原子发射谱对原子偶极矩和光场相对相位的敏感性，随着原子质心运动平均能量的增加，原子发射谱峰间的相对距离变小，峰高的变化与原子质心运动和光场所处的状态有关。

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).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
