After analyzing purple soil sampled from neijiang, leshan ofsichuan provinec and yuanmou of yunnan province, the contrast results of microbe quantity feature between surface and subsurface purple soil were obtained as follows. the content of soil organic matter, total and available nitrogen, phosphorous and potassium of surface was higher than subsurface, not relating to the type of purple soil and soil utilization way. the quantity of microbe _ bacteria, actinomyces and mould in surface purple soil was higher than subsurface, which indicated that the organic matter and airy condition in surface soil was more suitable for microbes growing. there was the same tendency in profile change of microbe quantity in purple soil located in temperate _ humid climate of sichuan basin in contrast with dry _ hot climate of yuanmou, yunnan. the nutrient situation of purple soil in sichuan basin shown that state of surface was better than subsurface, while in yuanmou of yunnan the state was on the contrary due to the degradation of surface soil
實驗室對四川內江、樂山和雲南元謀不同類型紫色土表層和亞表層微生物數量特性的比較分析表明：土壤有機質、氮磷鉀全量及其速效量均表現為表層高於亞表層，與紫色土類型和利用方式無關；三大類土壤微生物細菌、放線菌和黴菌數量均表現出表層高於亞表層，表明紫色土表層的有機質和通氣性優于亞表層，適宜於這三大類微生物生長；溫濕氣候條件下的四川盆地和乾熱氣候條件下的雲南元謀其紫色土微生物數量的剖面變化具有相同的趨勢，唯土壤營養狀況在四川盆地紫色土中表現為表層優于亞表層，而在雲南元謀紫色土中由於表層土壤的退化作用表現為亞表層優于表層的相反情況。 -
The control system of mould level is crucial to improve the slab quality in the continuous casting process, pid controller is used in the traditional mould level control, and it has some defaults, such as : at the start - up or finishing period of casting or during the changeover of tundish, pid control has a bad effect, its overshoot is large and its transient time is long ; the erosion of the tundish stopper and the submersed nozzles lead to the accuracy of control become bad ; the abrupt falloff of block in the submersed nozzles makes the level acutely fluctuate, and pid control can not overcome the disturbances resulted from the change of casting speed
結晶器液位控制系統是提高連鑄產品質量的關鍵環節，傳統的連鑄機液位控制方法採用常規的pid控制，存在如下不足：開始、結束澆注和換中間罐澆注時，控制效果差，超調量大，過渡時間長；塞棒頭和浸入式水口被腐蝕后引起控制精度差；浸入式水口堵塞物的突然脫落所引起的液位劇烈波動；無法克服拉速波動引起的擾動。 -

Comparing the color of dot with the standard color plate on the indicating card, the blue dot shows the relative humidity is securtiy, but the pink dot shows the relative humidity is insecurtiy, so you need to change the desiccant to avoid the mould of goods
把圓點所呈的顏色與指示卡上的標準色版對照，若呈藍色則表示相對濕度是安全的，若呈粉紅色，則表示相對濕度不安全，為防止貨物發霉請更換乾燥劑。 -
Surface hardness is strengthened by use of plasma nitriding technique to change microstructure of mould surface. on the basis of that, the major research works accomplished in this paper are as follows. hardness, resistant attrition, fatigue strength, resistant erode and resistant die burn of the materials are enhanced and the life of the mould is increased by five to ten times
本人根據近年來模具工業的快速發展，模具的表面工程越來越受到普遍重視，利用等離子滲氮技術可以改變模具表面的組織結構使表面硬度得到強化，提高了材料的硬度、耐磨性、疲勞強度、抗腐蝕能力及抗燒傷性，使模具的壽命提高5 - - 10倍。
