rat density
解釋
鼠密度-
Because it well reserves the chemical stability of inorganic glass, it has the following features : low density, low thermal conductivity, vapor impermeability, no water absorption, incombustibility, protection from mould and rat eating, high mechanical strength but easy to cut and able to bear all kinds of chemical erosions except the hydrofluoric acid
由於它完全保留了無機玻璃的化學穩定性，具有容重低導熱系數小不透濕不吸水不燃燒不霉變不受鼠嚙機械強度高卻又易加工，能耐除氟化氫以外所有的化學侵蝕。 -
Primary culture of rat preadipocyte were prepared from the epididymal, inguinal and perirenal the fat pads of male normal, healthy, 15 - 20 days sprague - dawley rats. the preadipocyte grew better under the condition of 37, 95 % humidity, 5 % co2, ph 7. 0 - 7. 2, centrifuged at 1000r / min, m199medium, and 10 % fetal bo vine serum, seeded at a density of 4 l04, 5 l04, / cm2. oil red o staining was the special method to distinguish adipocyte from other cells, gimsa and he could determine the stage of the adiopcyte differentiation through the number of lipid drop, size and the position of the nucleolus of the staining fat cell
經過多次實驗，確定本實驗室大鼠前體脂肪細胞的最佳培養條件是：溫度為37 ，濕度為95 ， co _ 2濃度為5 ， ph值為7 . 0 7 . 2 ，離心力為1000r / min ，培養基為m _ （ 199 ）培養基，胎牛血清濃度為10 ，合適細胞接種密度為4 10 ~ 4 、 5 10 ~ 4個/ cm ~ 2 ，染色結果表明：油紅o染色是鑒定脂肪細胞的特異方法， gimsa和he染色可根據不同區域染色程度、著色差別判斷細胞核的位置及脂滴大小、多少，觀察大鼠前體脂肪細胞分化過程中的形態變化，進而確定脂肪細胞的分化階段。 -

In cradle while cut down divides low - grade forest, notice to do authority of nice area branch and low layer vegetation clear the job, can reduce rat already kind concealment place, destroy mouse kind live condition, reduce rat kind density, can reduce miscellaneous bush to wait again at the same time right young forest competition, those who be helpful for forest is hale grow and shift to an earlier date closing cheng lin, the forest land after yu ren is shut goes against rat kind habitat, can rise to control rat to feel the effect that produces greatly
在撫育伐除劣等林木的同時，注重做好地面枝權及低層植被的清理工作，既可減少鼠類的隱蔽場所，破壞鼠類生存條件、降低鼠類密度，同時又能減少雜灌木等對幼林的競爭，有利於林木的健壯生長和提前郁閉成林，郁人閉后的林地不利於鼠類棲息，可以起到控制鼠害大發生的作用。 -
