A mechanism that interprets this phenomenon was proposed as follows : the adsorbents can interact with phospholipid of ldl through calcium ion cross - linking of the phospholipid phosphate groups of ldl and the carboxyl groups of sde ligands . on the other hand , the electrostatic interaction between the positive charge of the phospholipid choline nitrogen of ldl and the negative charge of carboxyl groups of sde ligands is enhanced by the calcium cross - linking of the phosphate groups of neighboring phospholipids in ldl 其可能的原因是:在吸附體系中如存在大量的cay ,一方面ca可以作為橋梁連接ldl所含磷脂極性頭部的磷酸基團和吸附微珠配體上的孩基;另一方面又可交聯相鄰磷脂間的磷酸基團,從而促進ldl所含磷脂極性頭部的膽堿n ”與配體竣基的相互作用。

It has high selectivity in adsorpting water , polar molecule or polarizable molecule on account of the existing of mighty coulomb field and polar interaction in the internal of crystal cave of zeolite , the high electric field gradient and the uneven surface caused by the exposure of exchangable cation of equilibrium framework negative charge in framework structures 由于分子篩晶穴內部有強太原理工大學碩士學位論文摘要大的庫侖場和極性作用,再加上骨架中大量平衡骨架負電荷的可交換陽離子的暴露造成的高電場梯度及表面的不均性,使其對水、極性分子及可極化的分子具有高選擇的吸附性能。

It is found that the surface potential of the negative charge bits are higher than those of the corresponding positive ones . when ferroelectric polarization switching occurs , the potential difference becomes even more remarkable . the origin of this phenomenon traced to the existence of internal field within the interface layer which is near the ferroelectric / electrode interface 研究發現pzt薄膜表面的電荷沉積與薄膜-底電極界面層內部的界面電場存在密切聯系,由此我們建立了一個界面電場模型,定性地解釋了pzt薄膜表面電荷沉積的非對稱現象。

The incorporation re3 + ions creates si - o - re bonds , which are more resistant to attack from water and may also reduce the concentration of silanol groups . furthermore , the presence of re in tetrahedral positions creates a negative charge on the surface of the pore walls , which repels the oh “ ions that catalyze the hydrolysis of siloxane bonds D ) rehms介孔固體其合成和焙燒樣品的凹stmasn ’ mr譜明顯不同于純硅樣品,樣品展示一個寬的共振峰,化學位移在6 。 101卯m和1llnnm ,對應于q ’和q ‘硅環境。

By static tests , studied the uf characteristics of the uf membranes , which have two kinds of intercept molecular eight , and made from pes , pek , spes and spk , in treating black liquid from basic straw pulp . the result showed : at the condition of static contacting , the pes and spes spk are polluted by composition of black liquid in a less degree , and the pek is in the heaviest edgree . the sulphonaled membranes with higher negative charge have better uf characteristics of black liquid . the uf membranes characteristics of 20 thousand intercept molecular weight are superior to 50 thousand intercept molecular weight 通過靜態試驗,研究了兩種截留分子量的聚醚砜、聚醚酮、磺化聚砜/聚醚砜、磺化聚砜/聚醚酮等超濾膜處理堿法草漿黑液的超濾特性,結果表明:靜態接觸條件下,聚醚砜及磺化類膜受黑液組份的污染程度較輕,聚醚酮膜的污染程度最重;荷負電性較高的磺化類膜具有較好的黑液超濾特性;截留分子量2萬的超濾膜特性要優于5萬的膜。

Have “ cancer disposition “ the temperament that the person must note to correct his , want to strengthen confidence to oneself , reinforce culture , learn psychology to adjust , reduce mental negative charge , reach the state with broad bosom gradually , this has important sense to preventing cancer 有“癌癥性格”的人一定要注重糾正自己的性格,要對自己增強信心,加強修養,學會心理調適,減輕精神負荷,逐漸達到胸懷寬廣的境界,這對于防癌有重要意義。

Additionally strong electrostatic attraction formed between the metallic cations and the anionics with a large number of negative charges on the terminal groups , which provided the synthesis of some nano - particles of complex structures with inducting skeleton 此外,由于陰離子表面活性劑端基帶有大量負電荷可以與金屬陽離子產生較強的靜電吸引作用,為一些復雜結構的納米粒子的合成提供了誘導骨架。

In essence , the beam pushes the lighter electrons away from the heavier positive ions , which in turn get left behind , creating a region of excess positive charge and a region of excess negative charge [ see box above ] 基本上,這會將較輕的電子從較重的離子中推開,這時候較重的離子會略為落后,而創造出一個帶有較多正電荷的區域及另一個帶有較多負電荷的區域(參閱上方在電子泡泡里) 。

Namely , the electric field at the drain - side edge of the gate decreases with the increasing of negative charge density in the surface , so the breakdown voltage of gaas mesfet ' s will increase 表面受主態的增多使表面負電荷密度增大,表面聚集的負電荷可以分散漏側柵邊緣處的電力線密度,減弱了柵靠漏一側的電場強度,擊穿電壓提高。

When the electric voltage between the positive and negative charges is large enough , discharges take place between clouds or between cloud and the earth s surface , and lightning is said to have occurred 當正負電荷之間的電壓到達某程度時,云與云之間或云與地面之間就會出現放電的現象,發出強烈閃光,這就是我們平時見到的閃電。

About how the electric charges in the nuclear stars are accumulated , especially negative electric charges that are similar to the nuclei with negative charges , this could be arranged by god 至于中子星上的電荷是怎樣聚積起來的,特別是負電荷,這相當于帶負電的原子核(反物質) ,這個問題也許是上帝安排的吧。

Zwitterion an ion with both a positive and a negative charge . amino acids and form zwitterions : the amino group has the form - nh3 + and the acid group is ionized as - coo - 兩性離子:既帶有正電荷又帶有負電荷的離子。氨基酸就是這樣一種離子:氨基基團為- nh3 +而羧基端為- coo - 。

In addition , after the binding of mp - 11 with la3 + , mp - 11 with the positive charges would diffuse toward to the glassy carbon electrode with the negative charge easily 另外, la ’ ”與mp刁1的鍵合使mpll帶正電荷,易向帶負電荷的玻碳電極擴散,進一步促進了mp

Qualitatively , the equations mean this : electric fields point out from positive charges and into negative charges , and magnetic fields curl around currents ( moving charges ) 定性地看,這個方程組意味著:電場是由正電荷指向負電荷,磁場圍繞著電流即移動的電荷。
