本文首先介紹了固體激光器多模運轉的速率方程，結合二次諧波的產生方程，給出了內腔倍頻固體激光器的動態方程。By ensuring that all inner surfaces of the valve are kept constantly wetted and vented to the upstream side when the valve is in the closed position, we have eliminated the conditions required for gas accumulation and caustic crystallization in the body cavity
為了確保所有閥門的內部表面能夠經常保持濕潤狀態，並在閥門關閉期間能將次氯酸鈉排出到上游位置，我們已經消除了閥腔內氣體積累和結晶體產生的必要條件。Spermal ultrastructure the sperm ultrastructure of the macrobrachium rosenbergii and exopalarmon carinicanda holthuis analogical, the whole sperm looks like a inversed umbrella, it has a main body, a spike and a little bit cytoplasm. there are some vesicle exist in the m. rosenbergii sperm nucleus. the relatively length of the spike of the e
各種細胞器數量在精子發生過程中逐漸增多，其中內質網以粗面內質網為主，線粒體于初級精母細胞階段始出現，膜輪結構在次級精母細胞中出現，精細胞早期的上述細胞器分化成電子密度高的前頂體腔，並逐漸分化形成方形頂體。The work mainly consists of four parts : the first part is to use oxidation and lpcvd technique to produce sio2 mask film and si3n4 insulation film in order to enhance the heating efficiency of micro chamber, and guarantee the carry out of the reaction. the second part is to use the combination of dry etching and wet etching to produce reaction micro chamber, it is the container which carry out the pcr reaction, and dna sample carry out amplification reaction here. the third part is to use the sputtering, photolithography to produce heaters and temperature sensors which heat the reaction micro chamber and provide the temperature condition for the pcr reaction
