The purification procedure described in this paper is quite simple. Addition of CaCl〓 helps to maintain oxygen activity and aggregate the membranes so that they can be conveniently pelleted in a short time by normal centrifugation instead of ultracentrifugation.

在提取液中加入一定浓度的Ca〓（Ca〓既有助于维持类囊体膜的放氧活性又可以使类囊体膜在较低的离心速度下使类囊体膜得到凝集沉淀），从而在较短时间内、在高速离心的情况下得到了纯度较高并具有较高放氧活性的发菜类囊体膜。

Spikelets 3–5(–6) mm, dark purple; glumes lanceolate, subequal or lower glume slightly shorter than upper, lower glume 1-veined, upper glume 3-veined, scabrid, apex acuminate; callus hairs ca. 1/3 length of lemma; lemma 3–4.5 mm, papery, hyaline at margins and apex, sometimes scabrid; apex irregularly 4-toothed; awn arising from upper 1/3 of lemma back or above, 1–2.5(–6) mm, straight or slightly curved; palea ca. 2/3 as long as lemma; rachilla conspicuously penicillate, 1.5–2 mm, including hairs up to 5 mm. Anthers 1.4–2.3 mm.

小穗3-5(-6)毫米，深紫色；披针形的颖片，近等长或下部颖片稍短于上面，下部颖片1脉，3脉，粗糙的上面颖片，先端渐尖；约的胼胝体毛1/3段外稃；外稃3-4.5毫米，似纸，透明的在边缘和顶，有时粗糙；不规则的先端4齿；芒生于上面外稃背面或在上部的1/3，1-2.5(-6)毫米，直或稍弯曲；大约2/3的倍于外稃的内稃；显著具毛撮的小穗轴，1.5-2毫米，包括头发可达5毫米花粉囊1.4-2.3毫米。

Petals yellow; flowers ca. 7 mm; middle outer sepal and apical appendage of keel pocketlike; stems without leaf scars and lenticels; leaf blade membranous, elliptic-lanceolate, ca.

A number of microplants with spherical, triangular, polyangular and boat-like shapes have been found both from the early Palaeoproterozoic Dashiling and Qingshicun Formations (ca. 2500- 2400 Ma) of the Doucun Subgroup of the Hutuo Group and the late Palaeoproterozoic Changzhougou and Chuanlinggou Formations (ca. 1800 -1700 Ma) of the Changcheng Group in North China. According to the features of these fossils, such as size, external shape and internal structure, they may belong to unicellular eucaryotic planktons.

在华北地区古元古代滹沱群豆村亚群的大石岭组、青石村组(约2500～2400 Ma)和长城群的常州沟组、串岭沟组(1800～1700 Ma)中存在着大直径的球形和形态呈三角形、多角形及船形微古植物，根据它们的大小、外部形态和内部结构等综合判别，它们可能属于单细胞真核浮游生物。

About the same time, CA was very strong too. Under the support of Big Sister Anita Mui, CA had also made many super stars. Its achievement might not be as big as Polygram, but it was very powerful too.

在差不多同期的华星唱片亦不遑多让，在梅艳芳这位大家姐扶助下，不断力捧出不少巨星，虽然成绩未及乐坛班霸宝丽金，但气势绝不逊色。

Ca 2+ at 1 64 mmol/L markedly increased ethanol tolerance of a self_flocculating fusant of Schizosaccharomyces pombe and Saccharomyces cerevisiae. After 9 h of exposure to 20% ethanol at 30℃, no viability remained for the control whereas 50 0% remained for the cells both grown and incubated with ethanol in Ca 2+_added medium.

生长阶段和冲击阶段均添加 1 6 4mmol LCa2 +能显著提高自絮凝颗粒酵母于 30℃在 2 0 %酒精冲击下的存活率，经过 9h冲击，对照组的存活率为 0 ，而添加Ca2 +试验组的存活率为 5 0 0 %，表明添加适当浓度的Ca2 +能显著提高菌体的耐酒精能力。

In the visual system, 5-HT/TPH-like immunoreactiveneurons (ca.35 per hemisphere) were mainly situated between the optic lobe and lateralprotocerebrum, the neurites of which either descended into the optic neuropils or ascendedinto the protocerebrum, thus possibly integrating the optic lobes and other brain regions. Inthe protocerebrum, 5-HT/TPH-like immunoreactive neurons (ca. 25) mainly distributed dorsalto the protocerebrum beside the Kenyon cells. Their axons directly projected into theprotocerebrum as well as the optic lobe.

TPH阳性神经元的类型、数目、分布位置、投射区域与5-HT基本相同。5-HT/TPH阳性神经元在视觉系统主要分布于视叶与侧前脑之间，每侧大约有35个，其轴突及分枝或下行进入视叶或上行进入前脑。5-HT/TPH阳性神经元在前脑分布于前脑背方、肯氏细胞两侧，大约有25个，轴突主要投射到蕈形体和中央复合体的广泛区域，另有个别神经元轴突下行投射进入视叶形成广泛分枝。

Culms to ca. 5 m, to 3 cm in diam.; internodes terete, 33–40 cm, initially densely pruinose, yellow-brown and unevenly dark gray powdery when old; wall ca. 8 mm thick; supra-nodal ridge more elevated than sheath scar.

秆与5米的约，在3厘米直径；节间圆柱状，33-40厘米，浓密最初具粉霜，黄褐色和不均匀深灰色敷粉老时；壁约8毫米厚；超级节的脊比鞘痕更多的隆起。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
