Results showed that the specific activity of nitrile hydratase per dry cell weight in engineered Rhodococcus strains driven by Ptac, Pami-1, Pami-2 and PlacZ was 7.5, 6.3, 5.3 and 1.8 times of that in the wild, respectively. It indicated that these promoters could be well recognized by RNA polymerase of Rhodococcus.

结果表明，启动子Ptac、Pami-1(7 bp SD-ATG间隔)、Pami-2(13 bp SD-ATG间隔)和PlacZ在紫红红球菌ATCC 33278中启动表达腈水合酶的比酶活分别是野生菌株的7.5、6.3、5.3和1.8倍，表明这些启动子都可以被红球菌的RNA聚合酶所成功识别。

Blood pressure, heart rate and their variabilities were measured in conscious, unstrained rats and middle pregnant rats. BRS of heart rate control was measured by using a bolus intravenous injection of phenylephrine (5 μg/kg).

在清醒、自由活动状态下测定妊娠SD大鼠和正常对照SD大鼠的HRV、BPV和自发性BRS；静脉注射去氧肾上腺素(5μg/kg)以测定压力反射对心率的控制功能。

In this paper, the reason of this phenomenon is firstly analyzed. Secondly, an algorithm of combining weight at high layer is proposed for SD, aiming to reduce the probability of accessing into the high layer of the tree in the searching process of SD so as to decrease the complexity.

在分析了这一现象的原因后，本文提出了在高层对权值进行合并的一种球形译码算法，因为其减小了译码搜索过程中对树的高层节点的访问的概率，由此降低了搜索复杂度。

This research take late-maturing variety adzuki bean Jihong-4 as the experiment material, After the photoperiod inducement at different leaf ages treatment, the result showed that the activity of NR under LF treatment is higher than CK treatment on the whole, and is lower than SD treatment; The content of the dissociation amino acid under these three treatments show a descend trend along with the leaf ages accretion, but the inducement increasing the content of dissociation amino acid, different leaf ages leaves show some difference, and alternating rise with SD treatment; Inducement can reduce the content of soluble sugar, and continuous inducement shows a accumulation effect; 2LF is the most sensitivity stage for soluble protein under photoperiodic inducement, From this stage, each leaf indumenta can reducing the content soluble protein, but continuous inducement reducing rising it.

本研究通过光周期诱导的方法，对中晚熟品种冀红4号红小豆进行不同叶龄进行处理，结果表明：所有叶龄处理下硝酸还原酶活性基本高于自然光处理而低于连续短日照处理下的；随着叶龄增大，各处理游离氨基酸总量均呈下降趋势，但光周期诱导可提高游离氨基酸含量，不同叶龄表现有所差异，与连续诱导交替上升；诱导可降低可溶性糖的含量，并连续诱导出现累积效应；2LF是光周期诱对可溶性蛋变化最敏感的时期，这个时期起单个叶龄诱导可降低可溶性蛋白含量，但连续诱导却可提高；LF处理下的类胡萝素总体含量高于另两个处理，而LF处理下的叶绿素含量在仅3叶龄前高于CK处理下的，随后出现下降趋势。

RESULTS Ouabain-like immunoreactivities were observed abundantly in the inner zone of adrenal cortex, known as the zone reticularis of SD rats and Macaca mulattas; weakly in the posterior pituitary of SD rats, but nothing in the hypothalamus.

结果 在大鼠和恒河猴的肾上腺皮质内侧网状带细胞中可以观察到丰富的哇巴因免疫反应阳性物质，垂体后叶有较弱的哇巴因免疫反应阳性物质，而下丘脑并未发现有哇巴因免疫反应物质存在。

It was found that water uptakes and swelling ratios of SPPBES increased as the increase of SD and temperature,and oxidative resistance decreased as SD and temperature increased.

SPPBES的含水率和溶胀率都随着磺化度和温度的升高而增大，耐氧化性随磺化度和温度的升高而降低。

Formal training classes had the highest response (M=4.41, SD=0.848). Of these delivery method, more than one-third (35.3%) of respondents perceived on-the-job training was the most effective learning activity, while nearly two-thirds (64.7%) perceived computer-based training courses were the least effective learning activity. As to using outside vendors for training programs, the summated mean of 3.15 (SD=1.241) indicated that outside vendors were only 'Sometimes' used to provide training.
