Through this experiment,it was measured that average diameter of the fundamental frequency light is 2.33 mm in the pattern of ordinary krypton pump,while in he pattern of the laster- diode bar pump the average diameter is only 1.25 mm,and the light field of the later also took on the standard Gaussian distribution,therefore formed the high-bright...

通过实验测量到普通氪灯泵浦方式中基频光的平均直径为2.33 mm，LD 阵列对称泵浦方式中基频光的平均直径仅为1.22 mm，并且呈现标准的高斯分布，形成了高亮度激光输出。实验研究了 Nd：YAG 调 Q 固体激光器的重复频率对 KTP 倍频晶体转换效率的影响。并且，在基频光平均功率11.2 w时，经 KTP 晶体倍频产生5.11W 的532 nm 绿光输出，光-光转换效率达到45.6%。

The results show that propellers operating in front of the liquid-cooled engine nacelle had higher take-off efficiencies than when operating in front of the radial engine nacelle; the peak efficiency was higher only when spinners were employed.

结果表明，在前面的推进器发动机实现了液体冷却效率更高的起飞了在前面比运行时的光线的引擎实现最高效率较高；只有当纺纱被聘用。

The results showed that the grain yield of winter wheat with two-irrigation was higher than that with one-irrigation with the same nitrogen application rate and method. Compared to one-irrigation,the grain number per spike in two-irrigation was higher,the 1000-grain weight was lower, the water wastage was higher, but the WUE was lower. The yield was not affected significantly by nitrogen rates and the methods. Within the nitrogen rate of 157.5-295.5kg/hm2, the lower NUPE and Nitrogen Productivity declined with nitrogen rate increasing. NHI was not lower than the others at the lowest nitrogen rate of 157.5kg/hm2. The accumulation of NO3--N in soil was significantly and positively correlated with the nitrogen application rate. NO3--N in one-irrigation was distributed mainly in the top layer (0-80cm), but it was inverse in two-irrigation.

结果表明，施氮量和施氮方式相同时春浇二水冬小麦的产量高于春浇一水，二水穗粒数较一水高，千粒重则低于一水，一水耗水量较少，水分利用效率明显高于二水；同一水分下不同施肥量及施肥方式对产量的影响差异不显著，同一施肥方式下在157.5-295.5kg/hm2范围内，施肥量越大，氮素生理效率和氮肥生产力越低，施氮157.5kg/hm2时，氮收获指数均处在最高或较高水平；土壤硝态氮残留量与施氮量呈显著正相关，成熟期一水条件下土壤中硝态氮主要集中在上层(0~80cm)，二水条件下则主要分布在中下层。

Little risk, high returns, great oversubscription and high turnover of Initial Public Offerings are long-standing obvious features of Chinese capital markets, which damage the market efficiency and the resource allocation efficiency.

This paper mainly inquired into the characteristics of the ferment bed pig - raising technique and its applying in realizing the cleaner production of pig farms. ferment bed ; cleaner production ; pig - raising technique ; waste treatment

但由于发酵床技术主要靠微生物降解猪场废物，而目前所使用的菌种分解效率不是很高，使得单位面积饲养的猪数量有限，另外由于猪舍是半开放式的，受外界的环境变化的影响，如何使菌种在不同的气候条件下都能发挥较高的效率也是一个需要解

Simultaneous heating and quenching with high power medium frequency equipment for parts of long shaft,adopting special induction coil and adjustable induction coil and self tempering ,will improve on medium frequency quenching quality of the parts and raise obviously productivity,thereby cause the enterprise to obtain fine product quality,high productivity and Low production cost.

Therefore,tapping potencial of remaining oil to improving oil recovery,the recognition of reservoir intraformational heterogeneity in channel sandbodies is proposed and the main targets of reservoir IOR in channel sandbodies of mature oilfields are pointed out as follows:①shutting off strongly-waterflooded intervals to control ineffective circulation of injected water;②strengthening water washing in medium-waterflooded intervals in order to achieve the aimed waterflood efficiency and even to exceed it;③enhancing injection-production consistency and injector-producer ratio of non-waterflooded or weakly-waterflooded intervals for the propose of realizing effective displacement and imporving conforma nce.

根据我国东部主力油田储层绝大多数都属于河道砂体，注水开发进入高含水阶段后，层内剩余油超过层间剩余油，层内矛盾上升为主要矛盾这一特点，从挖掘层内剩余油潜力出发，提出要重新认识河流砂体储层层内非均质性，并指出高含水期河流砂体储层改善采油目标主要有：①封堵强水洗段，控制注入水无效循环；②加大中水洗段注水冲洗强度，达到目标水驱效率，并有可能超过目标效率；③提高未、弱水洗段的注采对应程度和注采井数比，达到有效驱替，提高波及程度。

As the primary factor, alkabinity should condition were acquired. As the primary factor, alkabinity should be below 12g/L; the desulfurization effect is optimum when the ratio of tannic and sodiumm metavanadate was 1.5-2; the high absorption temperature is unfavour for desulfurzation 30~40癈 was proved to be effective through experiments.

并得出碱度是影响其脱硫效率的主要因素，总碱度控制在129几以下比较适宜；拷胶和钒在脱硫过程中只是起催化作用，且得到二者比例满足1.5一2时，脱硫效果最佳；温度对脱硫效率的影响主要是在较高温度下会促进副产物 NaZSZO3的生成，所以脱硫反应器中的温度不能太高，经实验证明一般控制在30一40℃。
