根据现有转炉设备条件，通过热力学计算确定转炉前期脱磷温度范围，并在现场实验中掌握好倒渣时机、渣碱度、加料量和出钢温度，确定最佳脱磷工艺。

objectiveto discuss the effect of the self-made negative pressure suction device in preoperative preparation of wound repair.methods27 patients who suffered soft tissue defect received the treatment of negative pressure suction device and underwent debridement during the time of dressing change, after 7 to 30 days （average 15.6 days） therapy, these wounds were repaired with skin grafts or flaps.resultsall of these patients' wounds became cleaner and smaller than before, and granulation tissue were fresh, the dermatoplasty or skin flap transplantation operations were successful.

目的：探讨自制简易负压吸引装置在创面修复术前期准备中的治疗作用。方法：对27例有皮肤软组织缺损的患者采用自制的简易负压吸引装置治疗，并在每次更换负压装置时进行清创。经过7～30日，平均15.6日的治疗后，在创面上行二期游离植皮或皮瓣转移修复术。结果：27例患者经过治疗后创面清洁，面积较前缩小，肉芽生长新鲜，游离植皮或皮瓣转移修复均一次性获得成功。

The core supposition in Zhu Guangqian's earlier works on aesthetics is to"purify the heart and soul", to make man"refined", thus indicating a strong spirit of secularity. On the other hand, he argues for"aesthetic detachedness","emotion-centeredness" and"the artistry life", manifesting an ideological trend identical to the modern western"aestheticism".

朱光潜前期美学论著的核心命题之一是"洗刷人心"，使人"脱俗"，具有比较强烈的入世精神；但是，他又主张"审美超脱"、"以情为本"、"人生的艺术化"，显露出与西方现代"审美主义"相似的思想倾向。

The main contributions are summarized as the following.Firstly, assuming demand is segmented by order lead time, a joint pricing and capacity allocation model is formulated considering scenario-based demand. Due to the stochastic discrete variable in the model, robust optimization is used to solve the model. Numerical examples prove our model and method reflect the stochastic characteristics of demand and provide more pratical pricing and capacity allocation policies than other methods of deterministic and stochastic expectation programming methods especially when the capacity is tight.

本文的创新之处概括为如下几个方面：首先，假设制造企业根据交货提前期对市场细分，建立了考虑需求情境的BTO模式下制造企业定价与能力分配的集成模型，利用稳健优化规划方法对此随机模型进行转化和求解，算例仿真表明随机优化规划方法较确定性规划和随机期望值规划方法更好地反映了随机离散需求的分布和波动特征，更加接近实际运作情况；产能越紧张，各类需求的价格差距越大，三种规划方法给出的最优策略差距越大。

There were detestably close synapses between homologous chromosomes during thellateprophase and early metaphase in mitosis of somatic cells.

发现在其有丝分裂的晚前期、中期阶段，咯对同源染色体都在进行联会。

Diakinesis The last stage of the PROPHASE in the first division of MEIOSIS.

终变期：减数分裂第一次分裂前期中的最后一个阶段。

Prophase may be divided into successive stages termed leptotene, zygotene, pachytene, diplotene, and diakinesis.

前期可被分为连续的阶段：细线期、偶线期、粗线期、双线期和终变期。

In evl-14 mutant animals, synaptonemal complexes were detectable at the pachytene arrest, but more than the usual six DAPI-staining positive structures were seen in diakinesis, suggesting that EVL-14/PDS-5 is important for the maintenance of sister chromatid cohesion in the late prophase.

这一结果提示EVL-14／PDS-5对于在减数分裂的晚前期维持姐妹染色单体粘连是十分重要的。

But the proportion of diapause increased if the eggs laid by females in all day light.
