Particular configurations on bedding planes and on the surface perpendicular to the bedding planes lead to different explanations for the genesis of these silty dykes:(1) they are considered as the oldest trace fossils of metazoan according to the spindle-crack of siltstones on the bedding plane and the sand-filling tube configurations on the surface perpendicular to the bedding plane;(2) they are considered as the liquefied sand-veins induced by earthquake according to the sinuous configuration of siltstone dykes on the surface perpendicular to the bedding plane and the obvious liquation feature.

由于该粉砂岩岩墙在层面上和层内具有特别的形态，因而对其成因具有多种解释：在层面上呈纺锤状粉砂岩裂缝以及在层内呈砂质充填管形态，从而被认为是最古老的后生动物遗迹化石；在层内呈弯弯曲曲的粉砂岩岩墙以及明显的流体化作用特点，所以又被解释为地震振荡作用形成的液化砂岩脉。

Stamens 5, usually inserted at base of corolla tube and adhering to stigma head to form gynostegium; filaments usually connate to form a tube enclosing ovaries; anthers 4-celled (Periplocoideae and Secamonoideae) or 2-celled, often with a membranous apical appendage; pollen tetrads contained loosely on a spatulate translator with a basal corpusculum, or pollen united into waxy pollinia, each attached through a caudicle to the retinaculum between adjacent anthers to form a pollinarium, pollinia 2 or 4 per pollinarium.

雄蕊5，着生于花冠筒的基部，与柱头贴生，和柱头粘生，形成合蕊柱；花丝通常合生成管包围子房；花药4室(Periplocoideae和Secamonoideae)或者2室的，通常有一膜质的顶端附属物；四合花粉松散地着生于匙形的载粉器上，具有着粉腺体，或者花粉合生成腊质的花粉块，通过花粉块柄与系接于着粉腺上，每个花药有花粉块2个或4个。

According to the classifing method of Geldart,ultrafine powders belong to group C particles.It is difficult to fluidize because of such cohesiveness.However,it was discovered recently that some powders can be fluidized smoothly through forming larger agglomerates at high gas velocity,and the fluidization quality of some powders can be improved by external force.

按Geldart的分类法，超细粉属难流化的C类颗粒，但近年来的研究表明，某些超细粉在高气速下可以形成较大的聚团，而以聚团形式实现平稳流化；对在高气速下难以流化的超细粉，人们通过引入外力场等方法来改善其团聚特性，提高流化质量。

It was found that the pemeability of the dust core was almost a constant in the frequency range from 1KHz to 100KHz,and the quality factor Q of dust core increased with increasing frequency.It was also found that Q became higher at the frequency over 50KHz in comparison with that of permalloy in higher frequency.

结果表明，在测量的频率范围内(1KHz-100KHz)，该粉芯的磁导率几乎不随频率变化而变化；粉芯的品质因数Q随频率的增加而增加，在较高频率时有着比坡莫合金粉芯还要高的值，具有应用价值。

That is, the business card printing and membership card making thousands of pieces of paper, in particular domestic uncoated paper or book paper occurs paper wool, paper powder in the rubber roller, imprinted on the edge of the paper and paper Mao superdirective (direction to bite or to drag-and-shoot direction), the not equal to the linear speed of the roller, only in the cylinder lining after business card printing and membership card when, in the rubber roller paper coated maoba non-directional well, then this data is only lining is the best, that is, until you reach the drum running as business card printing and membership card making ink plates and blankets, as well as on the status of the delivery is the best.

即制卡和会员卡制作几千张纸(出格是舶来胶版纸或书刊纸)后不离会不入现纸毛、纸粉粘在橡皮滚筒上，若痕迹边际的纸粉、纸毛有不圆向性(向咬口不圆向或向拖梢不圆向)，则表明不有到达滚筒线速度不不等，只有在滚筒包衬后制卡和会员卡制作时，在橡皮滚筒上纸粉纸毛堆得不有有不圆向性，那么这栽包衬数据才是最恶的，亦即滚筒调动到了运转最恶环境，制卡和会员卡制作历程洋油不朱在印版、橡皮布以及纸张上的传达是最恶的环境。
