In this paper, the factors that may cause crack breaking of concrete pavement of several built highways were analyzed systematically and thoroughly. From analysis to site experiments and calculation, it is believed that crack breaking is mainly caused by factors as follows: 1 、 Unqualified sedimentation and losing stabilization of the roadbedinduced crack in the early; 2、 Construction technology、 materials and incorrect treatment methodswere adopted;3 、 Crack breaking induced by thermal stress; 4、 Water cant circulate makes crack cause;With regard to the afore-mentioned problems, corresponding preventive measures, qualified control indices and site control approach are presented based on analysis theory and site experiments.

本文在全面系统地分析已建成的高速公路水泥混凝土路面产生的原因的基础上，通过现场试验及计算分析，确定了高速公路水泥混凝土路面裂缝的主要影响因素有以下几个方面： 1、路基的不均匀沉降、失稳是早期裂缝产生的主要因素； 2、施工工艺、材料问题及养护方法不当； 3、温度应力产生的裂缝； 4、排水不畅影响裂缝产生；针对上述问题，通过理论分析及现场数据提出相应的质量控制目标、现场控制方法。

The field measurement of solar array can analyze and assess the power efficiency of solar energy station. However, the traditional method does not be used widely in characteristics test and assessment of solar energy station because of its inconvenience and bulkiness.

太阳电池阵列的现场测试可以有效地分析和评价光伏电站的发电效率，但是由于传统的现场测试方法具有体积庞大、现场测试不便等缺点，使得这种方法未能在太阳电站的性能测试和评价工作中得以应用。

The relationship between in situ target strength and depth of chub mackerel was established by selecting the length composition of mackerel was larger than 90%. Results showed that the in situ target strength of chub mackerel was changed significantly depend on depth up to 8.7 dB. And it indicated that the measurement of in situ target strength of fish with swim bladder should be modified by the relationship of target strength and depth, especially in chub mackerel, it may be led to overestimate the standing crop to 7.4 times of the assessment.

将科学鱼探所收录到的白腹鲭声学资料使用线性回归来检定现场标物反射强度与样本所在水深关系，检定结果显示出白腹鲭在不同水深时所反射的现场标物反射强度均会随著深度改变，并且呈现负相关的显著水准(p.01)，现场标物反射强度变动有8.7dB差异量，对白腹鲭鱼群现存量会超估7.4倍的差异。

Preserved for more than 5,700 years, the structure was found in an ancient peat bog next to the Belmarsh prison in Plumstead, a suburb of East London near the banks of the River Thames .

封存了5700年仍然如此完整，而在挖掘现场找到其中的原因了：因为挖掘现场是在普拉姆斯特德的贝尔马什监狱一个沼泽地里，这个是位于东伦敦泰晤士河旁边的一个郊区。挖掘现场是在位于东伦敦泰晤士河沿岸郊区Plumstead的Belmarsh监狱附近的古代泥炭沼泽地里。

On the basis of study on a couple of prevailing fieldbus,combined with the development of fieldbus-based simulated monitoring system of marine engine room in Qingdao Ocean Shipping Mariners' College,which the author joins,the design and technical features of fieldbus systems are analyzed,the advantages to adopt fieldbus technology in narine engine room are discussed,the basic operating principle of LonWorks fieidbus is approached,the structural scheme of LonWorks bus-based monitoring and alarming system simulator of marine engine room is proposed,and the buildup and function thereof are detailedly expounded to some extent.

本文结合作者参加的青岛远洋船员学院机舱监测报警模拟系统的科研工作，在研究了当今流行的几种现场总线的基础上，分析了现场总线系统的结构特点和技术特点，论述了在船舶机舱中采用现场总线技术的优越性，探讨了LONWORKS总线的基本工作原理，提出了基于LONWORKS总线的船舶机舱监测报警模拟系统的构造方案，并对该监测报警模拟系统的组成、功能等进行了比较详细的论述。
