采用X射线荧光、X射线衍射、热膨胀等分析手段对比研究了安阳商代陶水管的制作工艺,发现陶水管化学成分中各类熔剂的质量分数均略高于对比陶片中熔剂的质量分数,CaO、K2O、MgO等助熔剂与A l2O3的质量比进一步证实该现象,而这种差异性则外在地表现为陶水管的气孔度低于对比陶片以及陶水管热膨胀曲线中出现玻璃化现象,该结果表明陶水管原料应为一种易熔粘土,或者在沉淀粘土中人为地掺和了草木灰类掺和料,这有利于陶水管烧制与成型,有助于熔剂在熔融状态下,较好地进入陶水管中的空隙,使陶水管变得更加致密,一定程度上有利于防止陶水管的渗水,显示出陶水管制作工艺的特殊性。

小麦不同品种向籽粒供应氨基酸水平的差异。籽粒蛋白质含量高的93-52各营养器官中的游离氨基酸含量均最高,说明93-52籽粒蛋白质合成所需底物供应充足,即源足,因而其籽粒游离氨基酸含量最高。鲁麦21和济南17相比,鲁麦21叶片中的游离氨基酸含量虽略高于济南17,但茎鞘和穗中的游离氨基酸含量却明显比济南17低,并且在后期鲁麦21营养器官中游离氨基酸滞留的多,向籽粒中的转移程度低,即流不畅,是造成鲁麦21籽粒游离氨基酸含量低的主要原因之一。

The effects and mechanism of GABAergic neurons, NOergic neurons, opioid peptide and cyclic adenosine monophosphate in the nucleus reticularis thalami on sleep-wakefulness cycle of rats and the effects and mechanism of the 5-HTergic nerve fibers project from the nucleus raphes dorsalis to RT on sleep-wakefulness cycle of rats were investigated with the methods of brain stereotaxic, nucleus spile, microinjection and polysomngraphy.1. The effects of GABAergic neurons in RT on sleep-wakefulness cycle of rats1.1 Microinjection of 3-mercaptopropionic acid (3-MP, a kind of glutamate decarboxylase inhibitor) into RT. On the day of microinjection, sleep only decreased a litter. On the second day, sleep marked decreased and wakefulness marked increased. On the third and fourth day, sleep and wakefulness stages resumed to normal.1.2 Microinjection of gamma-amino butyric acid (GABA 1.0μg) into RT enhanced sleep and reduced wakefulness compared with control; while microinjection of L-glutamate (L-Glu, 0.2μg) decreased sleep and increased wakefulness; microinjection of bicuculline (BIC, 1.0μg), a GABAA receptor antagonist, enhanced wakefulness and reduced sleep; microinjection of baclofen (BAC, 1.0μg), GABAB receptor agonist, had the same effects as GABA.2. The effects of NOergic neurons in RT on sleep-wakefulness cycle of rats2.1 Microinjection of L-arginine (L-Arg, 0.5μg) into RT decreased sleep compared with control, but there were on statistaical difference between L-Arg group and control; while microinjection of sodium nitroprusside (SNP, 0.2μg), a NO donor into RT, sleep marked decreased and wakefulness marked increased. Microinjection of nitric oxide synthase inhibitor, N-nitro-L-arginine (L-NNA, 2.0μg) into RT enhanced sleep and reduced wakefulness.2.2 After simultaneous microinjection of L-NNA (2.0μg) and SNP (0.2μg) into RT, SNP abolished the sleep-promoting effect of L-NNA compared with L-NNA group; after simultaneous microinjection of L-NNA (2.0μg) and L-Arg(0.5μg) into RT, we found that L-NNA could not blocked the wakefulness-promoting effect of L-Arg.3. The effects of opioid peptide in RT on sleep-wakefulness cycle of rats3.1 Microinjection of morphine sulfate (MOR, 1.0μg) into RT increased wakefulness and decreased sleep compared with control; while microinjection of naloxone hydrochloride (NAL, 1.0μg), the antagonist of opiate receptors, into RT, enhanced sleep and reduced wakefulness.3.2 After simultaneous microinjection of MOR (1.0μg) and NAL (1.0μg) into RT, the wakefulness-promoting effect of MOR and the sleep-promoting effect of NAL were not observed compared with control.4. The effects of cAMP in RT on sleep-wakefulness cycle of rats Microinjection of cAMP (1.0μg) into RT increased sleep and decreased wakefulness compared with control; microinjection of methylene blue (MB,1.0μg) into RT enhanced sleep and reduced wakefulness compared with control.5. The effects of the 5-HTergic nerve fibers project from DRN to RT on sleep-wakefulness cycle of rats5.1 When L-Glu (0.2μg) was microinjected into DRN and normal sodium (NS,1.0μg) was microinjected into bilateral RT. We found that sleep was decreased and wakefulness was increased compared with control; when L-Glu (0.2μg) was microinjected into DRN and methysergide (MS,1.0μg), a non-selective 5-HT antagonist, was microinjected into bilateral RT, We found that sleep was enhanced and wakefulness was reduced compared with L-Glu group.5.2 When p-chlorophenylalanine (PCPA, 10μg) was microinjected into DRN and NS (1.0μg) was microinjected into bilateral RT, We found that sleep was increased and wakefulness was decreased compared with control; microinjection of 5-hydroxytryptaphan (5-HTP, 1.0μg), which can convert to 5-HT by the enzyme tryptophane hydroxylase and enhance 5-HT into bilateral RT, could block the effect of microinjection of PCPA into DRN on sleep-wakefulness cycle.

It should be noted that not only in the complex perovskite like BaO3,(X=Mg, Zn, Co, Ni, Mn: Y=Nb, Ta) but also in the compounds with tungsten bronze structure such as Ba6-3xLn8+2XTi18O54, they are consisted of corner-sharing oxygen octahedra and the ratios of ion in B site to ion in A site are usually larger than one.
值得注意的是业已开发出来的材料不论是复合钙钛矿BaO_3,(X=Mg,Zn,Co,Ni,Mn;Y=Nb,Ta)还是钨青铜结构,它们都是由氧八面体共顶连接,而且氧八面体内、外阳离子比例都等于或略大于1,因此,我们推测在B位与A位阳离子比例略小于1的类钙钛矿结构中极有可能存在具有优良介电性能的新材料。

Speaking more generally, I ask that future priests, from their time in the seminary, receive the preparation needed to understand and to celebrate Mass in Latin, and also to use Latin texts and execute Gregorian chant; nor should we forget that the faithful can be taught to recite the more common prayers in Latin, and also to sing parts of the liturgy to Gregorian chant.
总而言之,我要求未来的司铎们,从他们进入修院接受陶成之日起,就要做好通晓拉丁语并能用拉丁语举祭的准备,要使用拉丁语课本,咏唱额我略。我们也不能忘记信友们,他们通过培训是可以用拉丁语诵念更多的日常祈祷经文的,也可以用额我略调咏唱礼仪中部分内容。真理、智慧與慈悲的光輝,請護佑我直至永恆!
