A better algorithm and corresponding real time implementation scheme are proposed. By methodic arranging the clocks of CPU and AD/DA, the scheme can not only scale the pitch in two octave range effectively, but also process the real time input audio for synchronous scaling output. The experimental results on Windows platform indicate the modest CPU and memory consumption, so as to meet the requirement of real time applications.

And the conditions in cell suspension culture of Mikania micrantha were studied. The results showed that sucrose was the compatible carbon sucrose, and 30g/L sucrose concentration can satisfy the growth of Mikania micrantha cell; ammonium was absorbed under different sucrose concentration that haven't demonstrated significant specificity, and was completely absorbed on the lag phase and the early logarithmic phase; while nitrate was mainly absorbed on logarithmic phase. The density-dependent of Mikania micrantha cell starting to grow and density-inhibited of cell growth were proposed, the fittest inoculating quantity of Mikania micrantha in cell suspension culture was 40g/L.

并对微甘菊细胞悬浮培养条件进行研究，结果表明，微甘菊细胞生长适宜的碳源是蔗糖，并且较合适的蔗糖浓度为30g／L；在不同蔗糖浓度下氨基氮的吸收差别不大，氨基氮在迟滞期和对数期前期已基本消耗完毕，对数期生长主要利用硝基氮，因而提出，在微甘菊细胞液体悬浮培养中，氮源可以采用初始低氨基氮浓度，对数期中间维持高硝基氮，而且对数期中逐步流加少量的氨基氮；微甘菊细胞迟滞期分裂启动存在密度依赖现象，对数期生长存在密度抑制现象，最适接种量为40g／L。

Cub-carrying also occurs among some other myrmecophagous mammals; therefore one explanation is that cub-carrying is necessitated by myrmecophagy since myrmecophagy entails a low metabolic rate and high energy expenditure in walking between food patches.

幼崽携带行为在其他食昆虫的哺乳动物中也存在；因此，一个解释是幼崽携带行为是食昆虫类哺乳动物所必须的，因为食昆虫类哺乳动物通常新陈代谢率很低而在不同的食物地之间穿行的消耗很高。

However, during borehole grouting pile construction of the present, round section piles are used universally. Generally speaking, the boreholes are drilled by a large diameter round piling bit. Because of the restriction of factors of the mud pumps, and drilling equipments, and drilling technique, it would result in such problems as fol lowing: a bigger cutting area and overlarge cuttings volume, and more hole bottom sediments, difficult cuttings discharging, and serverely repeat cuttings breaking, and using more concret grouting amount, and lower drilling speed, faster bit wearing, and longer working period, bigger material and labor ex haust, and higher engineering cost, unreasonable ratio of loading capacity to volume of pile foundation, and lower comprehensive economic benefits, and so forth.

然而，钻孔灌注桩施工中，目前最为普遍采用的是圆形断面桩基，一般采用大口径圆形基桩工程钻头，由于国内生产的泥浆泵、钻具及钻进方法等因素的限制，从而使钻孔破岩面积和体积过大，造成孔底沉渣过多，排渣困难且排浆量大，重复破碎问题突出，混凝土灌注量大，直接反映为钻进效率低、钻头磨损快、施工工期长、材料能耗和劳动消耗大、工程成本较高、桩基荷载能力与体积比不合理、综合经济效益不理想等，这些问题严重影响和制约着钻孔灌注桩施工技术的发展和进步。

It has ultra-low energy consumption when compared to other peristaltic pumps and maintains higher flow rates from a smaller pump size.

和其他蠕动泵相比，它还有着极低的能量消耗，以相对小的泵身拥有相对高的流速。

On the Japanese island of Okinawa, for example, people have a strikingly low rate of mental disorder—and Okinawans are notable fish eaters, even by the standards of a piscivorous country like Japan.

比如，在日本冲绳，罹患精神系统疾病的人口比率出奇的低，以日本的鱼类消耗水平来衡量，冲绳人对鱼类的喜好也是首屈一指的。

In order to make oil-extracting water meet the requirement of producing polymer solution,polyvinylidene fluoride is examined to treat oil-extracting wastewater to reach this goal.

一方面，由于配制聚合物需要大量的低矿化度清水，消耗大量的水资源；另一方面，聚合物驱油同时也产生了大量的含聚合物及油的污水。

Due to the professionality in this area for two decades, we have an effective cost control system, hence that we can offer a competitive price to achieve the Double Win Cooperation.

由于我们&精而专&的专业模式使得在操作优势产品时所消耗的成本更低，因此我们能够提供更具竞争力的价格，以期达到与客户双赢的目的。

Oncidium on 15 hrs light period and night break treatments exhibited heavier fresh and dry weights, lower total soluble sugar content in pseudobulb because nutrient translocated for inflorescence development, however water content was no significantly different. After treatment of 9 hrs and 12 hrs light period, the total soluble sugar content in pseudobulb of Oncidium was higher than other treatments because of consuming less nutrient transfered from pseudobulb due to poor inflorescence development and the quality of inflorescence also showed worse.

以15小时电照周期处理与暗期中断处理之植株乾鲜重较重，含水量则无明显差异，而假球茎内的全可溶性糖含量则较其他处理组低，因为花序发育时，假球茎内的碳水化合物转移到花序，以提供花序发育所需之养分。9小时电照周期处理组与12小时电照周期处理组方面，因为其花序品质较差，消耗的养分较少，故其假球茎内的全可溶性糖含量较高。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.
